II'I'here was a lack Attaining full employment and business cycles were the fundamental economic Income redistribution was considered, but only direct transfers (rather than a redistribution of human capi tal) were discus~led. ,,5 The study of human canital has currently resurfaced as a principle concern of economists, particularly in the analyses of Gary S. Becl<:er and Theodore Schultz. 1I01Jr current emphasi~~ Thurow states that on the nroblems of economic g-rmoJth and equitable distribution of income has highlighted the importance of such analysis, for increases in skill, talents, and knowledge have proven to be major contributors to economic 8'-'rowth •.. " Another reason for the Ctlrrent interest in human capi tal fo:r-mation, as seen by Thurow, is that at the present time .. "alte~ation of the distribution of human capital seems to be the politically preferred method of eliminating both poverty and income gaps between black and white.,,6 A major component in human capital formation is education. The role of education on income distribution is an important -3one. Paul C. Glick and Eerman P. Miller assert that "in our complex industrial society, educational attainment is one of the most important factors in determining the occupation:=ll and income levels to which 8. person can aspire. 11'7 3ecker and Chiswick cite evidence that Itschooling usually explains ,- a not negligible part of the inequality in earnings within a geographic:=ll area, and a much larger part of differences in inequality between areas." 8 The purpose of this paper the economics of hUman capital on investment in education . .. s to review the literature on ormation with speCial focus The Return on Investment in Education: Private Individuals invest in education in part for the same ." reasons that firms invest in physical capital, that is, they expect the investment to yield a rate of return that vvill make the investment profitable. Mark Blaug states that lIeducation is to some extent at least rep;arded as an investment good rather than a consumer good, because everyone recognizes the fact that extra education generates a stream of financial benefits in future years. II Thus, the theory of investment behavior caD be used to explain the demand for education. I~ill 9 Economists assume that "optimizing behavior lr govern the amount that an individual will invest in human capital. It is for this reason that Gary S. Becker and Barry H. Chiswick conclude th~t an individual will invest only that amount which "maximizes his economic welfare. ,1 10 There have been a number of attempts to determine the individual rate of return on investment in education. Conceptually, this does not appear to be a difficult problem, but in pra~tice the variables determining income differentials are extrem31y complex. 'rhe economic literature in this area stresses both the rates of return by using different computational meLlOds and the problems involved in isolating education from other variables vJhich determine variances in earninS':s. The ffii3thodology involved in estimating the returns to education 7aries froD one study to another. -4- The conclusions -5drawn often depend as much upon the method used to evaluate the data as they depend upon the data itself. One method may overstate :::-eturns because it takes too much into conGideration, while another will understate returnG because it overlooks certain benefits. Of the various methods used to evaluate those economic returns which a person receives through further education, Hansen asserts that use of the "rate of return" is a method much superior to the more conventional methods used. bein~ He :"eels that methods using "additional lifetime income or present value of addi tioTI.'J_l lifetime income r1 are not ne arly as valuable. 11 In h1:::: use of this method, Hansen observes 8_ high rate of return to investment in schooling and attributes to this, the basic attitude that this society has toward education. He sees thls high rate of return as an adequate explanation for our "t:radi tional faith in education. an education is a pm'Terful ~veapon fierce world which sllrrounds them. II To most people, Hi th "'Thich to attack the rather For this reason, Hansen feels that, again reflecting a high rate of r~turn to education, most indivlduals desire to "take advanta,g:e of as much as they c an. schoolin~ 12 Ii 1110rgan and lVIarttn have found another problem in estimating returns to education, related to the methodology used. They state that the number of hours that a person Horks does not "increase :3ystematically" with the amount of education attained. On the contrary, a "voluntary substituting of leisure for income ll occurs in various forms. Por this reason, they point out that if an investigator uses "annual earnings" as a tool in -6measuring the rate of return to education, he should beware of these benefits Vfhich may be overlooked. In $uch q l1situation, the use of' qnnual earninvs hiees some of the benefits of education. Thoug~ a hi~h 1113 rate of return to education has been observed by Hansen, it might be important to know how, at this point in time, the rate of return to education is c ho.n[""1 nl2: . Is it risinr;, fallin0: or staying relatively constant? Along this line of thought, ,James Ivlorgo.n and Charles Lininger conclude that flthe private and social value of inve;3tment in education is than nreir iously implied. great~er II It appears that this level of value will continue lias long as unskilled jobs are e=~iminated faster than the nu=nber of unskilled li'Torkers decline, and the demg,no for technically trained people increase faster than the supply.1I 14 I In an attempt to see if the '!increase in number and proportion of high school and college graduates during the pact generation has been Gssociated with a reduction in income differentials for the se groups, in the lone: run, II it shou.ld be remembered that if there are no changes in the demand for workers with a higher level of education, such a reduction would not be surprising. we woul~ have to conclude that the rate of return to further education is falling. P. Hiller If this reduction has occurred, then However. in the period studied by Herman (1939-1959), both demand for and supply of highly educB,ted workers were changing. Thus, vJ'hen we see, from the figures of his study, that a reduced supply of workers with -7educations 1)elovr eighth .'Srade level had "smaller relative income p;airci~ tna'l l'1.igh school g:raduates II and at the same t i1Jle, 'we see that the increased supply of college .g:raduates I!did not affect -Gheir relative income position, II the conchwion dra,,'m is " that the demand for more highly educated workers has kept paGe 'I'Ji th the incre8.i:3ed supply of tiorkers ... ,,15 In this way, lVliller implies that the rate of return has at least kept p9.ee, Dr is staying rel9..tively constant. Rensha-~v maJ{es th8 inference that lithe real cost of obt8.ini11,,! a hi9:her education, measured in terms of income forcQ'one and education expenses, has been increasing 'wi th respect to time, 16 which makes it necessary for returns to incre9.se in order for an in'festment in education to remain as proflta-ole as it has been. data ~'oJh Hmrever, he also has come IIp with ich supports tl'1e hypothesis IIthat the returns -from investment in higher education ho.'1e been declinin'! wi th respect to time, sug~esting that the forces responsible for shifting the supply of college i\raduates to the right have been strono.:er than the fcrces shiftinp:: demand. n17 Observin;;r: the tightness of the job mtu'ket for college graduates today, this hypothesis seems to hE~e some very sound support. A problem Hhich thou[jh the ~lick probabilit~y and Tl1iller observe is that, e'ren of succeeding in his financial pursult is increased by a person's continued investment in education, this investment does not necessarily lI.'Suarantee II the tlattainmentfl of that person's financial ~oal. 18 A ~reat variety of highly personal factors Can enter in to modify and possibly reduce -8the import9.nce of a -)articular individual's educational attainment.

It He estimates that this educational return is H:lTOUnd lO~ for collr~lY,e, and even more for high school and ~ . elernen~ary ' 1 . ,,20 scnoo vI. Lee Hansen states, "Bas ically, the marginal r9.tes of return rise with more schooling up to the completion of grade 8 and then gradually falloff with the completion of college. H21 The problem of isolating the individual's return to education from other fO.ctors is '1 c" tnlyblina: block which must be recognized and overcome, for it not, returns to education can not be 9.ccurately estimated. ftexperienc,~. Certain factors such as natural o.bili ty, social clas~3, family connections. and other :·{inds of education" have a defini te [3.ffect on an • d' . -L J" S Income. 22 In .1Vl(Ua_ These variables hi~hly complicate the issue of II megs urinp:: :'eturns to education, for return:s 9.ttributed to formal educgtion nay in fact be the result of one or more of these highly per:sonal factors. If any of these factors ';'Jere to be sinided out by Surton':Jeisbrod and Peter Farpoff, ability would be at the top of their list. They see ability as a most -9influential variable with re{(ard to "educational attainment,lI so important that th:::y feel its effect cannot be ignored, for if it were, the result of education in relation to earnings would be well overstated. To their list of influential variables.

Hilkinnon sugrests "on-the-10b and off-the-job trainin~, market imperfections, such ai, the lack of :m01'iJ"ledge of onportuni ties, and tradi tionbased "!iITage-salary scales" as possible factors ·which could cause substanti.g,l \Tariations in the returns that different people receive from the same amount of education. 24 We really don't have enough information about the 11relationship bet"·Jeen income and ability, the importance of on-the-job training," or the II s ignif ica:1.ce of education in the home. II If w·e could be fully equipecl with these tools, adjustments could. be made, so that the influe~ce of these factors would not be misconstrued as a return to investment in education. Hansen asserts that "full adjustments for these factors would have the effect of reducing the relati7e rates o~ return, espeCially at the higher levels of schoolinrr:. 1125 BecaW3e of the diverse nature of variables "relevant to the determ:Lnation of earnings" lVeisbrod rmd .' bet"1;'Jeen Hh!lt they call "schoolin,0.;" variables. variable'~ l~arp('.f'f' distinguish anrl 1'n:)11-schoolinp;1I The former have to do "\I]"i th the "quantity and qUE'.li ty of education receivecl1 and the latter lIdescribe the personal -10characteristics of an individual that influence earniD roc s.,,26 They "estimated that about one-fourth of the earnin::>:s differences are attributable not to differences in educational attainment, but to non-schooling factors ... ,,27 Assuming that a high school graduate who attends college does actlJ.9.11y earn more than one 1.[ho ,Q:'oes to work upon !2.rad1Jation from high school, \'101fle and Smith attempt to learn "ho","J differences in education affected the earnin~s of hi~h school graduates ,)f equal ability or of comparable family background. ,,28 Using high school ranldng as an indicator of ability, they tried to compare such ranks 1;ifi th the annual earnings of these students t'ilJ'enty year~~ later. The hig;hest ranl;:ing individuals were reported to have the highest incomes and the difference in incomes increased with the amount of additional education that individuals received "after finishing high school. 1129 From the data which the~T nresented, \'iolfle and Smith concluded that "the 'nan of high abtli ty and advanced education rece i ves substantially better relifard tr:an the man 1I[ho has one but not both of these attributes." 30 They further conc l'll.de, even more emphatically thrlt lithe :3.dvantage of higher education is greate~jt for those of highest ability. ,,31 ~l!eii3brod !:md Karpoff go on to SUbstantiate this view. Because they found a "tendency for the rate of increase of earnings o'rer time to be larger for graduates 1<.Ti th higher class rank, \I the:r conclude that those people 1;ifho have the ability and motivation neces~jary to be at the top of , the class list, are the people 'who benefi t most from an investment in hiEher -11- ed.ucation. 32 Rensha11 has not'3d a distinct "tendency for high i2:r ades to be associated. Hi th increased earnings and occupations. II i~'l nearly all profess ions In spite of the fact that high grad.es could provide a key to financial success, Renshaw finds a p';reat number of theE8 trbetter students" choosing a profession HHhich almost never pro'rides entree to the highest income bracl{ets. In fact, he observed that nearly I! 38?~ of "All graduates enter into lower-pay "professions such as teaching and the clergy. ra3 To VJeisbrod and Yarpoff, it appears that students of different ability levels probably won't receive the same value from a college education. The "marginal value 11 of such education will probably corresDond to each person's own ability. Therefore, they urp;e that direct quotation of lIaverage financial return ll fi,?:ures of a:tvanced ed.ucation to high school r;r8.duates be a\"oided, since these [}vera~~e ~ip,:l1res may be unfair ,'?ncl 1I34 _. "misle'ldin!T. " Giora Banoch believes that "there is probably a significant posi ti're correlation betl'Ieen sl.bili ty to earn income--a combination of natural and acquired ability traits--and the leve 1 of schooling achieved. ,,35 Renshalv sees as a dis tinc t possibility that "th8 more ability or natural productivity one possesses, the more he '(,vill stan1 to benefi t from addi tional education. ,,36 These vieHs of the influence of ability upon returns to education might lead us to follmf the conclusions of D.S. Bridp.;man. His view of the income differential between -12hi~h school and colle~e graduates Was substantiated throu~h the study of the educ9..tional anri ability patterns of veterans from World War II 8.ncJ f'rom studies of earnings and abili ties o~ college grad~ates. He feels that ability is a major reason for income differences between these two groups. Conseql.l-ently. he sees a da~l2'er of overestimating; the IImonetary" val1.}e of a co11ege education, for the effect of "higher abili ty le~rels and ather such factors have not been q-:lequately recognized. II)? Weisbrod concurs that generally, those students who stay in college have more abiIity, ambition and desire to learn. Their family backgrounds Hill often ha,re an influence on their ability to be Dlaced in a position after gradUation. Their parents are more l1kely to have II,job connections!! to get them started.
