The role of trust in business Anna E. Shaleva∗ September 7, 2016 Abstract This study investigates the effect of trust on entrepreneurship. Results based on General Social Survey (GSS) data suggest that the probability to be self-employed increases because of trust. The possible channel suggested for this finding is the change in risk aversion due to interpersonal trust. More risk averse individuals are workers while less risk averse are entrepreneurs.

Economic theories from Schumpeter to Baumol have highlighted that entrepreneurship is at the heart of change and innovation in a capitalist system. A growing body of research also emphasizes the role of entrepreneurs and the development of a vibrant small and medium size enterprise sector in economic development (World Bank, 2003). However, while most economists agree that entrepreneurs are central to the functioning of the economy, the economic profession is still far from a complete understanding of what drives an individual to start a new business. There are only a few notable exceptions in economics, such as Landier and Thesmar (2009), who look at demographic and psychological predictors such as who enters into entrepreneurial activity. These factors include risk aversion, IQ, or socioeconomic factors. One of the first papers analyzing the process of selection into self-employment is Lucas (1978) model, which shows that individuals who have higher entrepreneurial productivity start their own firms. Actually, both the economys output and individual profits are maximized if more productive individuals organize the production by others. For the same reason, Lucas model predicts that more productive entrepreneurs run larger firms. However, Lucas (1978) does not explain the individual characteristics that make an individuals productivity higher in entrepreneurial activity. The determinants of entrepreneur activity have been separated as: Individual characteristics (such as initial wealth or risk aversion) that make an individual more inclined to entrepreneurial activity; economic characteristics (such as taxes) of the area where an individual lives; and cultural values of the community where an individual lives. In this paper we are interested in the individual characteristics as a determinant of entrepreneurship. The objective of the paper is to fill the literature gap by studying the role of interpersonal trust for entrepreneurship. Trust has been shown to affect a wide 2 variety of economic outcomes e.g., growth, investment, but its role for business has not been fully investigated. The question we study is whether trust causes entrepreneurship or not. In our setting, trust could be considered as a proxy of risk aversion. Kihlstrom and Laffont (1979) show that, on balance, more risk averse individuals are expected to become workers, while the less risk averse become entrepreneurs. The empirical exercise in this paper tests Kihlstrom and Laffonts prediction relevant, however, for trust. The rest of the paper proceeds as follows: Section 2 describes the data, Section 3 the empirical specification and results and Section 4 concludes. 2 Empirical Analysis 2.1 Data To conduct the empirical analysis, I use GSS 1972-2014 Cross-Sectional Cumulative Data (Release 3, July 31, 2015). The GSS collects data on attitudes and behaviors of contemporary American society. The survey records hundreds of trends since 1972. It contains a standard core of demographic, behavioral, and attitudinal questions, plus topics of special interest. Trust is conventionally measured by recording respondents’ answers to the question “Generally speaking would you say that most people can be trusted/you can’t be too careful in dealing with people?”. The scale includes: 1 if “can trust most people”, 2 if “cannot trust most people” and 3 if the answer is “depends” (See Appendix, Table A1). However, a new binary dummy for trust has been generated, which equals 1 for trust and 0 for ”cannot trust” or ”depends”. Whereas, entrepreneurship is measured through a binary dummy equal to 1 if “self-employed” and 0 if “worker”. 3 2.2 Econometric Specification I consider the following linear model: SE = β0 + β1 Age + β2 F emale + β3 Black + β4 Educ + β5 Size + β6 T rust + u (1) The dependent variable ”Self-employed” is explained by age, gender, race,education, size of the place respondent lives in and trust. In this model, trust might be correlated with u. The rest of the explanatory variables are exogenous, but this variable is potentially endogenous in equation (1). In other words, trust is the only regressor correlated with an omitted variable that is included in u. The Instrumental variable (IV) method tackles the problem of endogeneity by using an observable variable z, not in equation (1) that satisfies the conditions: 1) Cov (z,u)=0 and 2) Corr (z, hhincome)6= 0. 2.3 Identification and main results This paper proposes the variable fear (afraid to walk at night in neighborhood) as an instrument for trust. I argue that this variable predicts interpersonal trust and at the same time is uncorrelated with self-employment. Table 1 presents the main results - both OLS and IV estimation. Trust affects positively the probability of self-employment - i.e. the effect under the OLS estimation is of size 1% while under the IV estimation its size is 18%. Age almost does not affect the probability of self-employment while gender has an effect where being female reduces the chance of self-employment by 6%-7%. Black respondents are also less likely to be self-employed compared to white and other races. Education has an ambiguous effect on self-employment - a slight positive effect under the OLS estimation and a slight negative effect under the IV estimation. The size of the place respondent lives has an economically insignificant effect on self-employment. 4 Table 1: Results: OLS and IV estimation Self-employed Trust OLS 0.0144*** (4.04) IV 0.186** (3.17) age 0.0020*** (19.88) 0.0012*** (4.07) female -0.0671*** (-20.05) -0.0694*** (-13.80) black -0.0467*** (-9.24) -0.0241 (-1.58) educ 0.0021*** (3.76) -0.0051* (-2.31) size 0.0000* (2.47) 0.0000* (2.51) 0.0345*** (3.62) 0.0945*** (5.29) 36542 18244 constant N * p<0.05, ** p<0.01, *** p<0.001. t statistics in parentheses.

The evidence favours a positive relationship going from trust to entrepreneurship. This result illuminates the role of trust in business and offers a space for policy formation. 6 Appendix Table A1: Descriptive statistics (1) Variable self-employed trust age female black educ size fear Obs 36,725 36,725 36,616 36,725 36,725 36,645 36,725 18,324 Mean .117631 .3830633 46.04381 .5379714 .1330701 12.89802 366.7926 1.608601 7 Std.
