We find that early-life cognition, especially for those with very low IQ scores, and schooling have a relationship with late-life financial literacy. If the trend continues towards very individualized retirement planning, with definedcontribution plans and private savings dominating much of retirement income, we will need to generate strategies to help these vulnerable populations with more limited cognitive functioning manage this increasingly complex financial world. The research reported herein was performed pursuant to a grant from the U.S. Social Security Administration (SSA) funded as part of the Financial Literacy Research Consortium.

Center for Financial Security WP 10-1 Early-Life Schooling and Cognition and Late-Life Financial Literacy in the Wisconsin Longitudinal Study While Americans are increasingly left to save and invest on their own for retirement, there is considerable evidence that many Americans are lacking the skills to effectively complete this task. One-third of adults in their 50s say they have failed to develop any kind of retirement saving plan at all (Lusardi 2003). Surveys of financial literacy find that most respondents do not understand basic financial concepts, including topics such as bonds, stocks, mutual funds, compound interest, loans, and mortgages (Agnew and Szykman 2005; Bernheim 1995, 1998; Hogarth and Hilgerth 2002; Mandell 2004, 2007; Moore 2003; NCEE 2005). Consumers are also ignorant about social security and work-related pensions, two of the most important components of retirement wealth (Chan and Huff Stevens 2003; Gustman and Steinmeier 2004; Mastrobuoni 2005). Consequently, in recent years, programs and initiatives have been developed to promote financial literacy and provide financial education to United States consumers. Most of these interventions have focused on providing specific financial skills to specific subpopulations (Collins and O’Rourke, forthcoming; Lyons et al. 2006). The results from these different programs and populations have been generally positive, but small (Bernheim and Garrett 2003; Collins and O’Rourke, forthcoming; Bernheim, Garret, and Maki 2001; Lyons et al. 2006; Way and Ang 2010). These studies are also only focused on short-term interventions and measure short-term outcomes (Collins and O’Rourke, forthcoming). Thus, while targeted and short-term financial literacy initiatives have blossomed and been the subject of research, we know much less regarding whether and how more generalized education (i.e., math and reading skills) and general cognition (i.e., IQ, which is in part shaped by schooling) impact financial literacy. Does having a low IQ in early life lead to poorer financial literacy and thus greater financial risk in late life? Consequently, this study examines the links between early-life cognition and schooling experiences and late-life financial literacy. Is early-life cognitive ability and schooling associated with financial skills later in life? This study employs an innovative approach to measuring financial literacy. In short, we capture individuals’ knowledge of their own financial situations, which is a prerequisite for good financial behavior. While our original goal was to look at a range of events across the life course, we decided to focus more tightly on early-life experiences, especially schooling and cognition. Because of this focus on early life, instead of emphasizing cognitive decline, we emphasize the relationship between education and IQ, providing a rich picture of these earlier life circumstances and their implications for late-life financial literacy. Future work will explore how later-life events help mediate these early-life predictors. Schooling and Financial Literacy The contrast between focused financial literacy intervention and general schooling as a means to producing better financial skills is based on a broader debate within human capital theory regarding the relative importance of general versus specific skills. Human capital theories emphasize that it is general skills, rather than specific skills, that schooling is so effective at producing (Becker 1962; Schultz 1962). But a recent debate has emerged about whether high rates of college completion are necessary or whether some students would be better off focusing on more skills-specific training, such as trades, as opposed to the general skill set offered by higher education (Lerman 2009; Vedder 2007). A similar, though less contentious debate, has focused health research. Should interventions to improve health emphasize general skills achieved via schooling or should interventions be targeted and focused on improving healthy behaviors and effective medical care use (Link and Phelan 1995)? In short, there has been a tension between the effectiveness of more general training received in primary, secondary, and postsecondary schooling versus more specific training targeted to enhance a range of life outcomes. To date, however, while the literature devoted to financial literacy can demonstrate a growing level of information regarding task and subgroup-specific interventions, there is much less research examining the broader effects of schooling and cognition. While intervention studies have demonstrated links between short-term, targeted learning intervention and positive outcomes, no studies have closely examined the secondary school experience (Barron and Staten 2009; Bell et al. 2009; Devaney et al. 1996; Lyons et al. 2006; Varcoe and Wright 1991; Wallace et al. 2010; Way and Ang 2010). And while nearly all studies find that more years of schooling in early life are linked to financial well-being and literacy across the life course (Cole and Shastry 2009; Lusardi and Mitchell 2007a), no studies have examined how or whether things like academic performance and particular kinds of coursework are linked to financial literacy. And only recently have some studies begun to explore the relationship between cognition and financial literacy. In part, this more recent literature has been catalyzed by findings that link cognitive ability to wealth (Lusardi and Mitchell 2005; Banks and Oldfield 2007; McArdle et al. 2009). The findings from studies focused on the link between cognition and actual financial literacy have been more mixed. Alan Gustman and colleagues (2010), utilizing the Health and Retirement Study (HRS), found no link between cognitive numeracy measures or fluid intelligence and knowledge of one’s pension plan and social security rules, such as eligibility ages and plan values. Fluid intelligence is the general capacity to think logically and solve problems in novel situations, while crystallized intelligence is the depth and breadth of an individual’s knowledge and his or her ability to actually use that knowledge. Contrastingly, Sumit Agarwal and Bhashkar Mazumder (2010) found that individuals with higher Armed Services Vocational Aptitude Battery (ASVAB) scores, which are more strongly correlated with crystallized intelligence, were less likely to make financial mistakes. In short, those with higher scores were less likely to use a credit card for a transaction after making a balance transfer on the account or inaccurately estimate the value of a home on a home equity loan or line of credit. Thus, prior research has not fully evaluated how the detailed schooling experience (i.e., academic performance and coursework) and general cognition (which is affected by schooling) may impact financial literacy. For example, does having a comprehensive slate of math classes help facilitate financial literacy across the life course (Peters et al. 2006)? Do strong basic literacy skills, as measured by the number of English courses one takes in high school, bear any relationship to financial literacy skills later in life? Does general cognitive ability, measured in early life, help predict later-life financial literacy skills. While Gustman and colleages (2010) also focus on financial literacy in late life, their cognitive measure was taken in late life. Cognition, however, especially fluid intelligence, changes as people age. Perhaps developing general knowledge and cognition in early life is a critical part of developing strong financial behaviors that are evidenced in late life. The argument that general cognitive skills, most of which are developed through general schooling, will positively affect financial literacy is based on the premise that what we need to know to be effective at financial management changes over time. For example, today, effective retirement financial planning requires an understanding of defined contribution plans, private investment accounts, and the nuances of social security policy. But in 30 years, policy and employment changes may require a very different set of skills. General cognitive skills, as opposed to very specific skills training, allow people to adapt and pick up new skills. In short, it provides people with the fishing rod, as opposed to the fish. If there is a link between these early-life schooling and cognitive measures and later-life financial literacy, this implies the importance of strong general schooling (including math and general literacy skills) to help prepare students not only for the job market, but to effectively manage their financial lives in an increasingly complex and ever-changing financial and policy context. The Challenge of Measuring Financial Literacy In recent years, while efforts have been made to promote financial literacy and provide better financial education to consumers, the term ‘financial literacy’ has been used without a clear consensus of what it constitutes and how it will lead to greater financial security. Researchers have attempted to create measures, however, that can be used to measure program impact and understand generally what predicts ‘financial literacy’ (Fox, Bartholomae, and Lee 2005; Lyons and Scherpf 2004; Lyons et al. 2006; Schmeiser et al. 2010; U.S. Government Accountability Office 2004). Though measures of financial literacy employed have varied considerably, they broadly fall into two groups, knowledge based and behavior based. Knowledge-based measures include things such as whether individuals can calculate compound interest or know the difference between a stock and a bond (Hilgert et al. 2003; Holden et al. 2010; FINRA 2003; Moore 2003; NCEE 2005; Lusardi and Mitchell 2007a, 2007b, 2007c; Lusardi 2008a, 2008b; van Rooij et al. 2007). This approach to measuring financial literacy assumes that if consumers have basic tools, they can use them to make better financial decisions. For example, a NASBE (2006) report argued that financial education is like all types of education, in which teaching the basics helps to develop the building blocks individuals need to make good financial decisions throughout their lives. Alternatively, measures can be action based, measuring whether individuals exhibit good financial behaviors (Moore 2003; ANZ Bank 2008; Lusardi and Tufano 2009). These kinds of measures capture things such as levels of financial debt, participation in pension plans, or adequacy of retirement savings. To be sure, some studies have examined the validity of the knowledge-based measures by using them to predict behaviors like retirement savings and debt levels (Lusardi and Tufano 2009; Lusardi and Mitchell 2009). Generally, however, the measures themselves do not overlap and capture both knowledge and behavior, although there is some evidence that they are correlated. We utilize a measure of financial literacy that supplements these existing measures with the virtue of being drawn from questions that are asked on many surveys. That is it does not depend on ‘financial literacy’-specific variables. In short, we attempt to capture an individual’s knowledge of his or her own financial situation. Our survey measures how knowledgeable individuals are regarding their own assets, their retirement savings, and their immediate financial resources. We know of only one other study that has attempted this approach (Gustman et al. 2010). Having knowledge of one’s own finances is a prerequisite for making good financial decisions. Further, unlike a more general knowledge-based measure, this measure gets at the knowledge individuals require to manage their own finances. A virtue and criticism of our measure is that it measures not only knowledge, but behavior as well. This reflects one of the controversies, discussed in this paper, about the appropriate measures of financial literacy—is it about knowledge, which may never be activated, or about behavior that achieves the literacy goals? Our measures reflect the efforts individuals have made to be precise and active in their financial life. There are likely many well-educated individuals who can identify the difference between a stock and a bond, but cannot say how much they have in their checking accounts. There are likely many who formally understand compounding but, even though on the verge of retirement, do not know how much their pension will be worth. That said, of course having complete knowledge of one’s existing financial situation does not guarantee good financial decisions. Individuals may know they have very low assets relative to their debt and still overspend, for example, or may know about their debt precisely because they have overspent in the past. One could argue, however, that these are still more financially knowledgeable individuals. And, we would argue, it is nearly impossible to make good financial decisions if one is not aware of one’s basic financial resources. Data and Methodology There are no better data available in the United States than the Wisconsin Longitudinal Study (WLS) to test the links between early-life schooling and financial skills in late life. The WLS encompasses a cohort of 10,317 Wisconsin high school graduates mainly born in 1939. The sample is generally representative of white, non-Hispanic high school graduates across the United States. Survey data were collected in 1957, 1964, 1975, 1992/3, and 2003/5. It is the longest-running longitudinal sample in the United States, with the first wave of data collected when the respondents were seniors in high school in 1957 and the most recent wave of data collected in 2004 when the respondents were in their mid-60s. It is the only United States data set with administrative and prospective data that allows one to explore the links between early-life schooling and financial literacy. While surveys such as the HRS collect measures at multiple time points for a sample of older Americans, the WLS includes a broad array of early-life schooling characteristics (including years of schooling, course content, and school performance and interest) not included in other studies of older Americans. One weakness with the WLS, however, is that it is a homogenous sample of white Wisconsin high school graduates from 1957. While this has obvious disadvantages, a relatively homogenous sample can help rule out unobserved variable effects that would arise from birth cohort, education level, and geographic area correlates. Though many observed variables can be accounted for, such as sex, there are numerous correlates, such as cultural differences, which are harder to account for but which are still potential confounders. While the original WLS sample contains over 10,000 respondents, this study analyzes just over half of that original sample (6,276 cases). Cases lost to follow-up include almost 1300 respondents who had died by 2004; approximately 1400 cases who refused to answer the phone survey in 2004, in which key questions for our analysis were asked. The remaining missing cases were lost due to information missing on key covariates (educational attainment and course content) or on the outcome measure. The WLS has been ongoing for over 50 years, making sample retention an obvious challenge. Yet, compared to the Panel Study of Income Dynamics (PSID), which lost 50 percent of its sample to attrition over a period of 21 years between 1968 and 1989 (Fitzgerald et al. 1998), the WLS has had strong sample retention. Outcome Measures. We developed a set of measures to establish whether or not individuals exhibit good financial skills and knowledge of their individual finances. We defined three measures based on the 2003/5 survey data. Descriptions of the variables are presented here. Appendix A discusses additional details regarding sensitivity analyses to test the validity of these measures. These measures are: • Percent of asset questions to which the respondent gave a precise answer • Knowledge of amounts in checking, savings, and money market accounts • Knowledge of the value of retirement accounts The first measure is intended to capture the respondent’s overall awareness of his or her current financial situation. This WLS-constructed measure is a simple accounting of the percent of total asset categories held by the respondent (and spouse, if married) for which the respondent can provide an exact dollar amount when asked in a series of 12 questions. Asset categories include property, account balances in retirement plans, and life insurance cash values. We include in our sample only those cases that completed the full series of asset questions. Respondents who refused to answer at least one asset question comprised about 10 percent of the full sample and were excluded from our analyses. The second measure is intended to capture day-to-day financial awareness. We construct a binomial variable from the answer to the question, ‘If you added up all of your and your spouses’ checking accounts, savings accounts, or money market funds, about how much would they amount to right now?’ The variable is coded as 1 if respondents provided a value and 0 if they stated that they did not know the amount. Respondents also had the option to refuse to answer. Just under 10 percent of the sample refused to answer this question and were thus excluded from these analyses. The final measure is intended to capture long-term financial planning skills. Are individuals aware of where they stand in relation to their retirement income plans? Individuals are asked whether they or their spouse ‘have any retirement plans that accumulate an account balance—examples include IRAs, 401(k)s, and profit-sharing plans.’ Approximately 75 percent of the sample reported having such a plan. Respondents were then asked ‘If you added up all of your and your spouse’s retirement plans that accumulate an account balance, about how much would they amount to right now?’ About 20 percent of those who reported that they or their spouse had such accounts reported that they didn’t know the value. Another 10 percent refused to answer and were thus excluded from the analyses. A binomial variable is defined for those with such a plan that is equal to 1 if the respondent reports a value and 0 if the respondent reports that they don’t know the value. Covariates. This first set of independent variables is intended to capture basic cognitive ability and the early acquisition of skills that are likely to enhance the ability of individuals over their lifetimes to read about, understand, rigorously critique, and act on complex information. Childhood Cognitive Ability/IQ. These scores, available through school district administrative records, are derived from the Henmon-Nelson Test of Mental Ability, which was administered to high school students in Wisconsin. The Henmon-Nelson test is considered a general measure of intelligence, but a recent analysis indicated that, although it captures both fluid and crystallized intelligence, it is more strongly correlated with crystallized intelligence (Pallier et al. 2000). It is important to note that although high school rank and IQ are correlated (r=0.58), there is still meaningful variation. We ran this variable as a series of three splines. The first was for IQ scores below 100; the second spline was for IQ scores from 100 to 120; and the third spline was for IQ scores above 120. Educational Attainment. This measure calculates years of schooling derived from the highest degree attained and number of years of higher educational attainment. The measure ranges from 12 to 20 years, with 12 being a high school graduate and 20 indicating the attainment of a PhD. High School Rank. This measure is a percentile rank based on high school grades [100–(rank in class/(# of students in class))*100]. Rank was then divided into quartiles. The general correlation between grades and standardized test scores is high at 0.9, which reduces concerns that grades or rank may reflect teacher bias (Willingham et al. 2002). Course Content. Three measures capture the kinds of courses students took in high school. Two math-related measures capture the presumed acquisition of advanced math skills, the general computational skills required for financial literacy. One of the measures indicates whether the student took physics or trigonometry. The second measure indicates whether the student took the average number of semesters of algebra, fewer than the average, or more than the average among the WLS cohort. The student could report up to four semesters of algebra. Over half of the sample reported they had taken two semesters of algebra. The third measure captures the acquisition of what we would label general literacy skills not specific to financial literacy, but necessary for reading and understanding complex writing. It indicates whether the student took the average number of semesters of English, fewer than the average, or more than the average. Students could report whether they took 0, 2, 4, 6, or 8 semesters of English. Confounding Covariates. This set of variables includes those that, if excluded, would lead to biased estimates of the influence of the previous set of covariates. This could be either because they are themselves causal of those skill acquisition attributes or because the confounding variables enhance the contributions of those skills. The most straightforward example would be parents of high socioeconomic status with their own financial skills who teach those to their children; as adults, those children would be more financially literate regardless of their high school course selections, which would also be influenced by their parents’ expectations. Parental Socioeconomic Status. It is critical to control for parental socioeconomic status because it may predict schooling measures (attainment, rank, coursework), cognition, and outcome measures. The parental socioeconomic status measure is a WLS-created factorweighted score ranging from 1 to 97. The score is based on: 1) highest number of years of schooling for respondent’s mother and father, 2) Duncan SEI occupational score for respondent’s father’s occupation, and 3) four-year average of parental income between 1957 and 1960, based on Wisconsin tax records. Basic Demographics. These measures control for the sex, age, and race of the respondent, although there is little variation by age and race. Analytic Techniques and Models The analyses include logit and ordinary least square (OLS) regressions. Because of differences in the relationship between the outcomes, covariates, and whether or not individuals had college degrees, we ran separate models for those with at least a college degree and those without a college degree. An OLS model was estimated of the predictors of the percentage of asset questions respondents answered. A logit model was employed for the binary outcome measures regarding whether individuals know the value of their pension accounts and whether or not they know the value of their checking accounts. The models included parental socioeconomic status (measured in 1957), basic demographics, childhood IQ (measured in 1955–57), high school rank (measured in 1957) and coursework variables (measured in 1957), and years of schooling (a composite measure based on reports in 1974, 1992/3, and 2004). Note that the years of schooling variable captures additional schooling beyond high school, but also throughout adult years. The WLS cohort was one in which women returned to school after child rearing. This subsequent schooling is important in capturing effects of later schooling on current financial acumen as well as reducing the greater influence in 1957 of gender (versus scholastic aptitude) on college and post-college attendance. Results The results from these analyses generally find that early-life experiences related to both schooling and cognition are linked to late-life financial literacy skills. But these effects vary in important ways across the sample. In particular, the effects of early-life cognition appear largely confined to those with IQ scores toward the bottom of the distribution of IQ scores and among those without college degrees. In contrast, the effects of additional years of school and early academic measures (including math classes taken in high school) are largely significant only for those with college degrees. Table 1 here Table 1 shows simple bivariate correlations between individual characteristics and the three outcome variables. Around 72 percent of respondents who had retirement savings accounts reported that they knew the value of their balance-accruing retirement savings plans. A slightly higher percentage of individuals who had such accounts knew the value of their checking, savings, and mutual fund accounts (81 percent). For the sample, on average 89 percent of total assets were reported with precise answers, without requiring estimates through the bracketing series. For most of the outcome measures, there are large and significant differences by gender, educational attainment, and IQ, those with fewer than 6 semesters of English in high school compared to those with up to 8 semesters of English, more versus fewer semesters of algebra in high school, and between those who took physics or trigonometry in high school and those who did not. These basic patterns held across the outcomes. The main variation from these themes was that the number of semesters of English in high school was not correlated with the bank account knowledge variable. Table 2 here Table 2 presents findings from an OLS model for which the outcome is the percentage of total assets for which respondents provided exact dollar values. We provide separate estimates for those with and without college degrees, a distinction that from our early estimates we concluded was important. We discuss the results for those with at least a college degree. Having more semesters of algebra (borderline statistical significance) and having taken trigonometry and/or physics were both positively correlated with the outcome. Both indicated that individuals provided exact dollar values for 1.6 percent more of their total assets. Being male had especially large effects on the order of an 8.6 percent difference compared to women. While parental socioeconomic status was negatively correlated with the outcome, its effect was small. Nevertheless, it is interesting to note that respondents who had come from a higher socioeconomic background actually had less knowledge of their asset levels. The second set of results in Table 2 is for those without college degrees. Unlike the effect for college graduates, the two bottom IQ categories were positively correlated with respondents’ knowledge of their asset levels. A gain of approximately 10 points in IQ in the less than 100 IQ range increased the percentage of assets reported with precision by about 3 percent. The effect of a 10-point gain for those in the 100–120 IQ range was 2 percent. High school rank had an effect for this group. Among those who did not go to or complete college, there was a 2.6 percent difference for those at the top compared to the bottom quartile of their high school class. Cognition and academic performance were correlated with asset knowledge for this sample, but coursework in high school was not. But like those with college degrees, being male was strongly correlated with having more knowledge of one’s asset levels (a 9 percent difference between men and women). Table 3 here The results in Table 3, in which the outcome is knowledge of the value of respondents’ retirement plans that accumulate a balance (such as a 401(k)), parallel the results in Table 2. We provide both odds ratios and marginal effects. For college graduates, both additional levels of schooling and being male were correlated with knowing the value of one’s retirement account accumulations. Each additional year of schooling increased the odds of knowing the value by 25 percent, representing a 2 percent increase in the probability. The odds that a man knew the value of his retirement savings account were 4.6 times higher than a comparable woman, a 17 percent difference in the probability. In contrast, for those without a college degree, being male had a smaller but still significant influence and cognition had significant effects. The odds ratio for a 10-point difference in the less than 120 range was about 1.02. In probability terms, each 10-point increase led to a 3–4 percent increase in the probability of knowing one’s private pension account value. Table 4 here The results in Table 4 are for the outcome relating to whether the respondent knows the value of his or her checking accounts. Both odds ratios and marginal effects are presented. For college graduates, the only even marginally significant covariate, besides being male, was the number of algebra courses taken in high school. The odds of knowing one’s checking account balances were 34 percent higher (or a 2.5 percent difference) for those who took the highest number of algebra courses compared to those who took the average number. But for those without college degrees, the results roughly paralleled the prior outcome variables (asset knowledge and retirement savings account knowledge). In short, for those with IQs between 100 and 120, the odds ratio was about 1.28 (or 3 percent) for each additional 10 points of IQ. Sensitivity Analyses. Sensitivity analyses conducted on all three outcomes altered covariates included in the model, but did little to change our main conclusions. In the various alternative models, we excluded the English variables, based on the concern that coursework patterns were correlated in high school; altered the algebra coursework variable so that the reference was 0 semesters of algebra, in order to identify the key differences in effects among the categories; and varied cutoff points for the IQ splines. None of these variations altered the basic general findings across these models. We plan additional sensitivity analyses, including variations in how we treat individuals with missing covariate values. For example, missing values on high school rank were simply excluded, which if missing for individual-specific administrative reasons (e.g., individuals who had moved recently) could bias our results. Findings on Financial Literacy for Vulnerable Populations What are implications from these analyses for vulnerable populations? First and foremost, these analyses indicate that as the retirement context shifts toward one that requires significant financial literacy skills, individuals with more limited cognitive functioning may fare poorly. If the trend continues toward very individualized retirement planning, with defined-contribution plans and private savings dominating much of retirement income, we will need to generate strategies to help those with more limited cognitive functioning. About 20 percent of the sample fell into this category. And it is important to keep in mind that this is a relatively well-educated sample. Consequently, it is likely that a larger portion of the general population faces challenges in acquiring effective financial literacy skills due to cognitive functioning. Implications and Conclusions The main findings from this paper are that early-life cognition, especially for those with very low IQ scores, and schooling do have a relationship with late-life financial literacy. In this paper, we have defined financial literacy as the level of knowledge one has regarding one’s own personal finances. We use data that are often collected in surveys and thus can provide insight into financial knowledge across populations, even when financial literacy is not targeted in a survey. It seems reasonable to argue that these questions reflect levels of financial literacy required by individual circumstances: 1. Can you precisely identify all of your assets and their value? 2. Can you identify the value of assets most immediate to day-to-day financial transactions, such as your checking accounts? 3. Can you identify the value of assets important to life-course planning, such as your retirement savings accounts? The effects of early-life cognition were significant, but confined to those at the very bottom of the IQ distribution. In short, cognitive effects were found only for those without college degrees and the differences were only statistically significant among those in the lower IQ brackets, especially for those with IQ scores in the bottom portion of the distribution. These findings differ from Gustman and colleagues (2010), who found in the HRS that a numeracy measure was not predictive of knowledge of pension and social security rules. There are a few possible explanations for these differences in findings. First, it is not clear that Gustman and Steinmeier tested for nonlinear effects. Second, while their numeracy measure is strongly correlated with fluid intelligence, the Henmon-Nelson used in our study actually measures a mix of both fluid and crystallized intelligence. Fluid intelligence is the general capacity to think logically and solve problems in novel situations, while crystallized intelligence is the depth and breadth of an individual’s knowledge and his or her ability to actually use that knowledge. So it may be that fluid intelligence is less important than crystallized intelligence. Indeed, the Agarwal and Mazumder (2010) study also used a cognitive measure that is more clearly correlated with crystallized intelligence, and they found it to be quite predictive of financial literacy skills. It is important to keep in mind that education has demonstrable effects on cognitive scores. And because these scores were taken in high school we cannot be certain to what extent these differences are actually driven by prior schooling experiences. We have controlled, however, for family background characteristics, which are also correlated with IQ measures. It is also possible that these early IQ scores have some predictive capacity for laterlife cognitive decline. We expect to explore whether and how current cognitive functioning explains these early-life cognitive relationships. For those with college degrees, the main findings, other than gender effects, were that schooling experiences were linked to one’s financial literacy in late life. The number of years of school beyond a college degree mattered. High school math coursework also mattered, while English coursework never had a significant effect. This suggests that math-specific skills may matter more than general reading comprehension to understanding financial content. That coursework variables were not significant for those who did not go to or complete college may be a product of students who did not continue onto college having that decision shaped by their math performance. Though we do control for IQ, we cannot rule out the possibility that the link between math classes and financial literacy is the product of intrinsic quantitative capacity rather than something learned, although it is interesting that the only prior study to look at a measure of numeracy, which captures this underlying proclivity, did not find a link between it and financial literacy. While it would have been helpful to have more detailed measures of coursework, including performance in those courses, to sort out these issues, this analysis provides some evidence that the content and amount of early-life schooling has some relationship to financial literacy skills in late life. The findings also varied to some extent across the outcome variables, though this variation was largely confined to those with college degrees. The relationship between schooling characteristics and the outcome were strongest for the percentage of asset values known and weakest for knowing checking account values. The asset variable measures knowledge of one’s overall financial picture. We note, however, that a person with a more complex portfolio would be more challenged to know all asset values precisely, while someone with only a checking account would more likely score high on this variable. Thus, the variation in findings could reflect the fact that the kinds of higher-order skills linked to schooling are only important for more complicated outcomes. It is much easier to state the value of one’s checking account as compared to knowing the value of a complex array of assets. We were not entirely surprised by the large gender differences in knowledge. On the other hand, the variables were only defined for individuals who said they knew they held a particular asset. We did conduct separate analyses of men and women by educational group (college/noncollege). The years of schooling and cognitive effects were roughly comparable to the findings reported here. The problem was simply that the samples became too small to draw firm conclusions. Thus, while we were assured by these subgroup analyses, we hesitate to draw strong conclusions from them because of small sample sizes. There remains a need to explore what drives these gender differences, especially in a cohort where gender affected additional schooling, marriage, and other intermediate outcomes. There are some caveats to this study that should be addressed. First is the variation in outcome variables. The percentage of people with knowledge ranges from 79 percent for the retirement savings outcome to 88 percent for the asset knowledge outcome. As mentioned above, this percentage is likely to be influenced by the complexity of portfolios, a fact that confounds this as a measure of financial knowledge alone. We do find interesting relationships even with this relatively small variation in the outcome variable. But ideally, it would be useful to define variables that capture the greater variation in knowledge that has been exhibited in financial literacy surveys. Hence, we are pursuing other measures of financial outcomes to discover measures that vary more substantially in terms of knowledge. Another caveat regards the sample selection. All of the analyses excluded those who refused to answer. Prior research demonstrates that these individuals tend to be higher income and wealth individuals. We are not certain of the impact on these analyses of this exclusion. In the appendix, we describe some work on this issue and detail why we conclude that the exclusion of these individuals does not invalidate the general findings presented here. The two binary variables are defined only for those who hold the particular asset. This of most concern for the pension variable; about 20 percent of the overall sample did not have such an account. Clearly, these individuals are a select group, with those having accounts also more likely to have characteristics that affect the probability of their knowing account values. Those who do not have pension accounts are more likely to be women, to have low incomes, and to have low educational attainment. These findings about financial knowledge predictors must be understood to reflect relationships only for individuals who are likely to have these kinds of market-based, individualized (defined contribution) retirement savings accounts. It is also important to consider that the interpretation of these measures and analyses must vary depending on the respondent’s age. For example, an individual age 40 being unsure of the exact value of a retirement account is less policy problematic than is a 60-yearold individual contemplating retirement. It is only as retirement approaches that the precise value of these accounts has a more immediate impact on individuals’ financial situation. Thus, precision in answers is arguably an especially relevant measure of financial literacy for those approaching retirement, although a more ‘ball park’ knowledge is important to younger savers. One advantage of the WLS data is that it avoids this variation in relevant knowledge—these are all retirement-age individuals. As is always the case when using the WLS data, the findings must be understood in the context of its population; these are all high school graduates and members of a very specific cohort. These analyses cannot tell us how those without high school degrees fare, although the link between lower cognitive scores and financial literacy gives some indication of what that relationship may look like. Analysis of this cohort is valuable for understanding influences on financial knowledge of younger individuals in the sense that the members of the WLS cohort hold assets that prevail today and are faced with the same challenges of understanding them. Retirement income is dependent on how careful and knowledgeable individuals are as they face a financial landscape that changes for both young and old (e.g., new rules allowing conversions of IRAs and 401(k) assets into other forms). As already noted, about 80 percent of the sample had defined-contribution retirement savings plans (like 401(k)s), which are accounting for a growing share of retirement assets for both younger and older cohorts. The final caveat is that while we see these associations between cognition, schooling, and late-life financial literacy, we cannot claim these are entirely causal relationships. However, our childhood measures are prospective and in some cases (like for cognition) based on administrative data. So the study does provide a unique contribution for understanding the links between early-life factors and late-life outcomes. More generally, the results speak to the importance to later-life financial literacy of general skills. Thus, while targeted interventions later in life are likely effective, these results emphasize the importance of more general skills, which are achieved through schooling in early life and perhaps in mid life as well. The specific skills needed to manage finances effectively have changed dramatically over time. Having general skills that enable adaptation to changing financial circumstances are likely critical for financial well-being.

Appendix: The Validity of Financial Literacy Questions Our financial literacy measures are based on several key assumptions, which we will test in this section. One assumption is that individuals providing an exact response do actually know the exact value of their assets. A second is that those who respond ‘I don’t know’ are indicating lack of awareness of amounts even within some reasonable margin of error, rather than simple uncertainty about the exact value of accounts at the time of interview. Finally, we exclude from our variable definition those who refuse to answer necessary questions. The implicit assumption is that these refusals are randomly distributed across the sample rather than being more likely to have characteristics correlated with the outcome variable. The results discussed below provide some assurance that these are assumptions that, at least, do not lead to biased results. We provide a range of estimates to help validate that individuals are giving accurate answers if they provide an exact value of their assets. Because we do not currently have administrative data to do a clear test, we perform a few sensitivity analyses to test the potential accuracy of the responses. First, the fact that women are much less likely to report specific asset values as compared to men helps confirm that individuals are answering honestly. Tests of financial knowledge (i.e., how to calculate compound interest), like the findings presented here, indicate that women are much less likely than men to exhibit strong financial literacy skills (Lusardi and Mitchell 2008). Second, the IQ findings also provide some assurance regarding response validity. Again, as do prior studies that test financial knowledge, we find that those with lower cognition levels are much less likely to report specific asset values. We also test whether men, perhaps not wanting to appear unknowledgeable, report values even if they do know the values of varying assets. To test this hypothesis we utilized a measure of masculinity. Respondents were asked in the 2004 follow-up mail survey, ‘To what extent do you agree that a man should always try to project an air of confidence even if he doesn’t really feel confident inside?’ Responses ranged from strongly agree to strongly disagree. The response distribution was a normal bell curve. We reran models only on men and included this measure to test the hypothesis that men, especially those with very traditional notions of what constitutes being a man, may report values for assets categories even when they do not know them. We found no evidence to support the hypothesis. This measure showed no ability to predict whether respondents reported a value versus reporting that they don’t know. We would have expected that those who always felt like they had to ‘project an air of confidence even if [they don’t] really feel confident’ would be less likely to report that they don’t know the value of an asset (such as their pension value or checking account value). We found no evidence that this was true. In addition to concerns about inaccurately reporting specific asset values, another issue is whether those who respond ‘I don’t know’ are actually indicating a lack of awareness of amounts rather than simple uncertainty about the exact value of accounts at the time of interview. Again, our findings regarding gender differences and cognitive factors so closely parallel prior studies predicting financial literacy; this provides some assurance that we are getting at a true lack of knowledge. But we also performed some additional analyses to further test the validity of this concern. In particular, we explored differences between those who reported that they did not know the value of their checking accounts or their retirement accounts and those who initially reported that they did not know but then provided answers in the form of bracketed values or within a certain range of values. A similar pattern of findings held across these groups, but the differences were much wider between those who never provided an answer versus those who provided an exact answer, compared to those who provided an answer through bracketing versus those who provided an exact answer. Those with lower IQs, women, and those with more limited educational attainment were more likely to provide no values at all or values through bracketing than to provide a specific value. Finally, we explored the implications of excluding from the analyses those who refused to answer. In particular, we wanted to be certain that those who refuse are actually distinct from those who say that they don’t know the value of their asset categories. It is possible, for example, that some individuals simply reported that they don’t know as a polite way to refuse to respond. Thus, we compared those who refused to answer with those who said they don’t know the value of their ‘retirement plans that accumulate an account balance,’ those accounts including IRAs, 401(k)s, and profit-sharing plans, and their checking account values. Table A1 shows the basic differences in the descriptive relationships between the covariates and those who refused to answer versus those who reported that they don’t know the value of their varying assets. In short, the table demonstrates that the main differences (gender, cognition, and educational attainment) we saw between those who reported that they didn’t know the value of their assets and those who reported a specific value were much larger than when comparing the differences between refusals and those who provided an exact asset value. Insert Table A1 Indeed, we ran subsequent regression analyses to further explore the descriptive differences presented in Table A1. The first set of analyses was for a sample that included respondents who either reported a specific value of their retirement account balance or refused to answer. We estimated the probability of refusal. An identical analysis was done for a sample that included only those who either reported a value of these accounts or reported they did not know that value. The test was whether the predictive variables were similar— implying refusals and don’t knows are virtually the same answer—or different, which would imply the validity of their distinct treatment. Gender played an important, different, and expected role in these sensitivity analyses. First and foremost, the predictive value of gender was much smaller for a refusal than a ‘don’t know’ response. This is consistent with the literature that finds women possess lower financial literacy than do men. This leads us to conclude that our ‘don’t know’ predictors do predict knowledge, while refusals are caused by wealth-related factors. Refusing to answer questions on financial measures is disproportionately high among those with very high asset levels (Juster and Smith 1997). These gender differences inspired us to run these sensitivity models separately for men and women. For men, IQ and academic measures were not predictive of refusal to answer asset questions. In contrast, for men, education and IQ was predictive of ‘don’t’ know’ answers, and in the expected direction. Among women, however, we found a more complicated story. We found evidence of reporting bias in the opposite direction than what we initially assumed. It appears women may have been more likely to refuse when they did not know asset amounts. Women who refused to answer had lower IQ scores and were less likely to have taken advanced math courses in high school. In sum, the evidence of these sensitivity analyses indicates, that if anything, our exclusion of refusals from our sample may actually underestimate the effects of early-life schooling, especially for women.
