reputation formation in economic transactions abstract we investigate patterns of information transmission and the evolution of behaviour in standard trust games where reputational information can be exchanged between individual agents within a population but does not become public we vary the nature of information that could be transmitted either a subjective rating or the objective details of a transaction as well as the cost of information transmission either zero or positive we find that information transmission is heavily used if it is costless but only moderately if it has positive cost objective information effectively increases the average amount sent in the trust game and thus efficiency and average profits as well as the return rate only if transmission is costless and therefore is heavily used subjective information a rating only increases transfer and return rates in a control treatment where it becomes publicly available but not for private communication a detailed analysis of the determinants of information transmission shows a positive influence of a the transfer made to a receiver b experience of exploitation and c points to reciprocity in information transmission

can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

group reputations stereotypes and cooperation in a repeated labor market reputation effects and other regarding preferences have both been used to predict cooperative outcomes in markets with inefficient equilibria existing reputation building models require either infinite time horizons or publicly observed identities but cooperative outcomes have been observed in several moral hazard experiments with finite horizons and anonymous interactions this paper introduces a full reputation equilibrium fre with stereotyping perceived type correlation in which cooperation is predicted in early periods of a finitely repeated market with anonymous interactions new experiments generate results in line with the fre prediction including final period reversions to stage game equilibrium and non cooperative play under unfavorable payoff parameters

social preferences under risk equality of opportunity versus equality of outcome this paper axiomatizes a utility function for social preferences under risk in the model a single parameter captures a preference for equality of opportunity i e equality of exante expected payoffs relative to equality of outcome i e equality of ex post payoffs in a deterministic environment the model reduces to the model of fehr and schmidt 1999 the model is consistent with recent experiments on probabilistic dictator games

skill biased technological change and rising wage inequality some problems and puzzles the recent rise in wage inequality is usually attributed to skill biased technical change sbtc associated with new computer technologies we review the evidence for this hypothesis focusing on the implications of sbtc for overall wage inequality and for changes in wage differentials between groups a key problem for the sbtc hypothesis is that wage inequality stabilized in the 1990s despite continuing advances in computer technology sbtc also fails to explain the evolution of other dimensions of wage inequality including the gender and racial wage gaps and the age gradient in the return to education

earnings restatements and differential timeliness of accounting conservatism abstract we examine whether basu s 1997 differential timeliness metric and the related c score metric are effective in detecting predictable differences in conservatism surrounding corrections of overstated earnings cross sectional and time series analyses employing 2132 firms making restatements during 1999 2005 suggest basu based metrics capture variation in conservatism further we find that increases in conservatism following restatements are contingent on improvements in corporate governance collectively these results provide evidence of the usefulness of the basu based metrics in the restatement setting

social surplus determines cooperation rates in the one shot prisoner s dilemma abstract we provide evidence on how cooperation rates vary across payoff parameters in the prisoner s dilemma pd using four one shot games that differ only in the payoffs from mutual cooperation in our experiment participants play only the pd game and play the game once and only once so there are no potential confounds or methodological issues our results show that higher monetary payoffs from cooperation are associated with substantially higher cooperation rates which increase monotonically from 23 to 60 participants beliefs about cooperation rates track closely actual cooperation rates higher cooperation is expected from others when mutual cooperation payoffs are higher this is true also for participants who in a follow up experiment only make guesses about the choices of others

assessing policies to equalize opportunity using an equilibrium model of educational and occupational choices abstract the inter generational correlation of education in the u s is tremendous for instance in psid data from 1990 young males with college educated parents had a 70 chance of attending college but those with high school drop out parents had only a 15 chance in this paper we analyze the impact of college attendance bonus schemes designed to increase college attendance rates and pv of lifetime income of youth from disadvantaged backgrounds of course policies that increase the supply of skilled labor may reduce the college wage premium see heckman et al heckman james lochner lance and taber christopher explaining rising wage inequality explorations with a dynamic equilibrium model of labor earnings with heterogeneous agents review of economic dynamics 1 1998a 1 58 heckman james lochner lance and taber christopher general equilibrium treatment effects a study of tuition policy american economic review 88 2 1998b 381 386 this may have the unintended consequence of wiping out most of the gains to the targeted groups the strength of such equilibrium effects on wages depends on the substitutability between different types of labor thus it is important to evaluate education subsidies within an equilibrium framework that allows for flexible patterns of substitution across factor inputs this is exactly what we do here using an overlapping generations equilibrium model of the u s labor market fit to psid data from 1968 to 1996 the model allows for imperfect substitution among types of labor differentiated by education gender age and ten 1 digit level occupations a much finer differentiation than has been considered in prior work we find that very large college attendance bonuses are necessary to equate college attendance rates between youth whose parents had only high school degrees or were high school dropouts and youth whose parents attended at least some college the size of these bonuses far exceeds any reasonable measure of college costs suggesting the costs the bonuses overcome are primarily psychic or effort costs for example youth from disadvantaged backgrounds may be poorly prepared for college this suggests that bonuses targeted at college age youth are probably a very inefficient way to reduce inequality earlier intervention is likely called for

market exit through divestment the effect of accounting bias on competition we analyze the effect of accounting bias on the competition and market structure of an industry in our model firms interim accounting reports on investment projects may contain bias introduced by the mandatory accounting system we find that this bias strictly decreases firms profits when investors do not have an abandonment option but different results emerge when we allow the investors to divest in the interim specifically a conservative accounting regime may increase the likelihood of projects being discontinued inducing some firms to exit from the product market and leaving rivals to capture their market share a conservative regime can thus soften market competition and result in ex ante higher investment payoff higher consumer surplus and higher total social welfare since industries often have common reporting standards we also identify the degrees of industry wide accounting bias that maximize the expected investor payoffs finally we allow for investors to coordinate their divestment

reputation transmission without benefit to the reporter a behavioral underpinning of markets in experimental focus reputation is a commonly cited check on opportunism but it is often unclear what motivates an agent to report another s behavior when it is easy for the aggrieved individual to move on in a sharply focused laboratory experiment we find that many cooperators pay to report a defecting partner without the possibility of pecuniary benefit when this has the potential to deprive the latter of future gains and to help his next partner we illustrate how a social preference can explain such costly reporting and also discuss evidence for a role of emotions jel c91 d03 d63

zero as a special price the true value of free products when faced with a choice of selecting one of several available products or possibly buying nothing according to standard theoretical perspectives people will choose the option with the highest cost benefit difference however we propose that decisions about free zero price products differ in that people do not simply subtract costs from benefits but instead they perceive the benefits associated with free products as higher we test this proposal by contrasting demand for two products across conditions that maintain the price difference between the goods but vary the prices such that the cheaper good in the set is priced at either a low positive or zero price in contrast with a standard cost benefit perspective in the zero price condition dramatically more participants choose the cheaper option whereas dramatically fewer participants choose the more expensive option thus people appear to act as if zero pricing of a good not only decreases its cost but also adds to its benefits after documenting this basic effect we propose and test several psychological antecedents of the effect including social norms mapping difficulty and affect affect emerges as the most likely account for the effect

changes in u s wages 1976 2000 ongoing skill bias or major technological change this article examines the determinants of changes in the u s wage structure from 1976 to 2000 our main empirical observation is that changes in both the level of wages and the returns to skill over this period were primarily driven by changes in the ratio of human capital to physical capital we show that this pattern conforms extremely well to a simple model of technological adoption following a major change in technological opportunities in contrast we do not find much empirical support for the view that ongoing factor augmenting skill biased technological progress has been an important driving force over this period

earnings quality in uk private firms comparative loss recognition timeliness abstract uk private and public companies face substantially equivalent regulation on auditing accounting standards and taxes we hypothesize that private company financial reporting nevertheless is of lower quality due to different market demand regulation notwithstanding a large uk sample supports this hypothesis quality is operationalized using basu s 1997 time series measure of timely loss recognition and a new accruals based method the result is not affected by controls for size leverage industry membership and auditor size or by allowing endogenous listing choice the result enhances understanding of private companies which are predominant in the economy it also provides insight into the economics of accounting standards

the contracting benefits of accounting conservatism to lenders and borrowers abstract this paper examines the ex post and ex ante benefits of accounting conservatism to lenders and borrowers in the debt contracting process i expect conservatism to benefit lenders ex post through the timely signaling of default risk as manifested by accelerated covenant violations and to benefit borrowers ex ante through lower initial interest rates consistent with these predictions i find that more conservative borrowers are more likely to violate debt covenants following a negative price shock and that lenders offer lower interest rates to more conservative borrowers

financing and investment efficiency information quality and accounting biases in this paper we investigate the effect of accounting biases on firms financing decisions and the role of accounting biases in endogenous information quality we show that in industries with generally low profit prospects a downward biased accounting system performs better than a neutral accounting system and a more downward bias helps mitigate both investment and financing inefficiency whereas for industries with generally high profit prospects an upward biased accounting system is better than a neutral accounting system and a more upward bias helps improve financing efficiency in addition we find that a more downward biased accounting system motivates good firms to exert more effort to improve the information quality which improves overall efficiency this paper was accepted by mary barth accounting

implications for gaap from an analysis of positive research in accounting based on extant literature we review the positive theory of gaap the theory predicts that gaap s principal focus is on control performance measurement and stewardship and that verifiability and conservatism are critical features of a gaap shaped by market forces we recognize the advantage of using fair values in circumstances where these are based on observable prices in liquid secondary markets but caution against expanding fair values to financial reporting more generally we conclude that rather than converging u s gaap with ifrs competition between the fasb and the iasb would allow gaap to better respond to market forces

a measurement approach to conservatism and earnings management this paper formalizes a two step representation of accounting measurement and uses it to formalize a general rationale for conservatism as a measurement principle a transaction s economic substance manifests itself in characteristics of the transaction and an accounting rule is a mapping from transaction characteristics to an accounting report managers who have stakes in the accounting report are able to influence transaction characteristics such earnings management is ex post rational for managers but ex ante inefficient to safeguard against such ex post opportunism the optimal ex ante accounting rule is conservative in the sense that it requires more verification of the transaction characteristics favorable to managers thus this rationale for conservatism is as general as the managers ability and incentive to inflate transaction characteristics by opening the black box of accounting measurement the two step representation also formalizes some classic accounting concepts such as relevance reliability verifiability verification and accounting motivated transactions

management by the numbers a formal approach to deriving informational and distributional properties of unmanaged earnings we explore the theoretical relation between earnings and market returns as well as the properties of earnings frequency distributions under the assumption that managers use unbiased accounting information to sequentially decide on real options their firms have and report generated earnings truthfully with the market pricing the firm based on those reported earnings we generate benchmarks against which empirically observed earnings returns relations and aggregate earnings distributions can be evaluated this parsimonious model shows a coherent set of results reported losses are less persistent than reported gains decision making diminishes the s shaped market response to earnings and earnings relate to returns asymmetrically in the way documented by basu 1997 furthermore the implied frequency distribution of aggregate earnings is neither symmetric nor necessarily single peaked instead it may exhibit a kink at zero and look similar to the plots reported by burgstahler and dichev 1997 however within our model none of these phenomena are due to reporting noise bias or some undesirable strategic managerial behavior they are the natural consequences of using past earnings as the basis for value increasing managerial decision making that in turn generates the future earnings on which future decisions will be based

the effects of the minimum wage on the employment and earnings of youth the employment and earnings effects of the minimum wage are estimated by parameterizing a hypothesized relationship between underlying market employment and wage relationships versus observed wage

accounting conservatism and the efficiency of debt contracts in this paper we examine how accounting conservatism affects the efficiency of debt contracting we develop the statistical and informational properties of accounting reports under varying degrees of conditional and unconditional accounting conservatism consistent with basu s 1997 description of differ ential verifiability standards optimal debt covenants and interest rates on debt are derived from a natural tension between debt holders and equity claimants we show how optimal covenants vary with the degree of conservatism and de rive an efficiency metric that depends on the degree of conservatism we find that accounting conservatism actually decreases the efficiency of debt contracts contrary to the suggestions of watts 2003 and contrary to the hypothesis in numerous empirical studies

computerisation and wage dispersion an analytical reinterpretation the rich countries have recently seen a dramatic rise in income inequality all the more surprising because the long term trend had been toward equality this paper examines one of the leading explanations computerisation in the workplace i offer a theory of computers impact on white collar work which goes far toward explaining the timing form and locus of recent labour market changes the theory looks at the bureaucratic and organisational applications of computers that have been first largest and most influential they have two effects on firms demand for labour at different skill levels

on the relation between conservatism in accounting standards and incentives for earnings management this paper studies the role of conservative accounting standards in alleviating rational yet dysfunctional unobservable earnings manipulation we show that when accounting numbers serve both the valuation role in which potential investors use accounting reports to assess a firm s expected future payoff and the stewardship role in which current shareholders rely on the same reports to monitor their risk averse manager current firm owners have incentives to engage in earnings management such manipulation reduces accounting numbers stewardship value and leads to inferior risk sharing we then show that risk sharing and hence contract efficiency can be improved under a conservative accounting standard where absent earnings management accounting earnings represent true economic earnings with a downward bias compared with under an unbiased standard where absent earnings management accounting earnings represent true economic earnings without bias

accounting information in financial contracting the incomplete contract theory perspective this paper reviews theoretical and empirical work on financial contracting that is relevant to accounting researchers its primary objective is to discuss how the use of accounting information in contracts enhances contracting efficiency and to suggest avenues for future research we argue that incomplete contract theory broadens our understanding of both the role accounting information plays in contracting and the mechanisms through which efficiency gains are achieved by discussing its rich theoretical implications we expect incomplete contract theory to prove useful in motivating future research and in offering directions to advance our knowledge of how accounting information affects contract efficiency

revisiting the link between minimum wage and wage inequality empirical evidence from new zealand abstract this paper revisits the contentious link between the level of the minimum wage and wage inequality this is done utilizing the differential rates of minimum wage increase experienced by two age groups youth and adults in new zealand over the period 1997 to 2007

optimal impairment rules abstract we study the optimal accounting policy of a financially constrained firm that pledges assets to raise debt capital for financing a risky project the accounting system provides information about the value of the collateral absent accounting regulation the optimal accounting system is conditionally conservative it recognizes an impairment loss if the asset value is below a certain threshold but never reports unrealized gains we describe the optimal impairment rule and the optimal precision of the accounting information and we provide comparative static results that lead to testable predictions on the determinants of impairment rules

black white wage inequality in the 1990s a decade of progress mary c daly using current population survey data we find that the gap between the wages of black and white males declined during the 1990s at a rate of about 60 percentage point per year wage convergence was most rapid among workers with less than 10 years of potential experience with declines in the gap averaging 1 40 percentage points per year using standard decomposition methods we find that greater occupational diversity and reductions in unobserved or residual differences are important in explaining this trend general wage inequality tempered the rate of wage convergence between blacks and whites during the 1990s jel j15 j31 i introduction following the passage of the civil rights act of 1964 and other measures aimed at reducing labor market discrimination during the 1960s the differential in average weekly wages between black and white men in the united states narrowed substantially among male workers aged 18 64 the black white wage gap fell from 50 in 1967 to 30 in 1974 or by about 1 per year 1 after 1974 however the proportional difference in black and white wages remained essentially constant at 30 through the end of the 1980s following more than a decade of stasis the black white wage gap once again began to decline during the 1990s narrowing at an average annual rate of about 60 percentage point per year a great deal of past research has focused on why the black white wage gap did not continue to decline following the initial progress made through the mid 1970s see for example bound and freeman 1992 and juhn et al 1991 hereafter jmp the results point to a number of important factors including shifts in industry demand greater occupational crowding relative deterioration of unobservable skills among blacks and rising overall male wage inequality see altonji and blank 1999 for a detailed review of this literature in this article we investigate the role that each of these factors played in the wage convergence observed in the 1990s we begin by documenting the recent progress in black white wage convergence placing the 1990s in the context of the past 30 years following previous researchers we then use standard decomposition techniques to examine the role of individual characteristics the employment structure and overall male wage inequality in reducing the racial gap in earnings during the decade of the 1990s we find that greater occupational diversity and reductions in unobserved or residual differences are important in explaining this trend general wage inequality tempered the rate of wage convergence between blacks and whites during the 1990s ii data we use data from the march current population survey cps for the years 1969 1999 as administered by the u s census bureau for the u s bureau of labor statistics these files provide information on earnings hours and related variables for the calendar year prior to the survey date thus our analyses apply to income years 1968 1998 in the formal decomposition analysis we focus on three periods 1968 1979 1979 1989 and 1989 1998 these years span our sample and generally coincide with three business cycles our sample consists of black and white males ages 18 64 who participated in the labor force at least 39 weeks worked at least 1 week during the year and usually worked full time workers who are enrolled in school are excluded from the analysis throughout the analysis we focus on two groups our full sample and men with less than ten years of potential experience i e min age education 6 age 18 2 our empirical analysis focuses on weekly earnings calculated as the ratio of annual earnings to weeks worked during the year weekly earnings are deflated using the personal consumption expenditure deflator from the national income and product accounts to avoid problems associated with changes in cps top coding procedures over the years our sample excludes individuals in the top and bottom 1 of the weekly earnings distribution

rank regressions wage distributions and the gender gap in this paper we propose a novel rank based procedure to decompose changes in the gender wage gap into three components changes in the skill distribution changes in the wage structure and improvements in the position of women in a distribution of reference using cps data from 1979 and 1991 we perform the decomposition at each percentile of the wage distribution and show that the results are sensitive to the choice of distribution of reference male versus overall wage distribution we also find that relative wage gains of women may have been a source of increasing wage inequality among men

does the new economy measure up to the great inventions of the past abstract during the four years 1995 99 u s productivity growth experienced a strong revival and achieved growth rates exceeding that of the golden age of 1913 72 accordingly many observers have declared the new economy to be an industrial revolution even more important than the second industrial revolution of 1860 1900 which made the golden age of productivity growth possible this paper dissects the recent productivity revival subtracts out a cyclical component and concludes that there is no revival of the productivity growth trend in the 88 percent of the private economy lying outside of the durables manufacturing sector the paper explains this surprising finding by pointing to limitations in computers and the internet in comparison with the great inventions of the past

performance measures in earnings based financial covenants in debt contracts this paper examines how performance measures are defined in major earnings based financial covenants in loan contracts to shed light on the economic rationales underlying the contractual use of performance measures i find an earnings based covenant is typically based on a performance measure close to earnings before interest tax amortization and depreciation expenses ebitda however my empirical analyses show that ebitda is less useful in explaining credit risk than earnings before interest and tax expenses ebit and even the bottom line net income thus measuring credit risk cannot fully explain the choice of accounting performance measures in earnings based covenants i conjecture that contracting parties choose an ebitda related measure instead of a measure calculated after depreciation and amortization expenses e g ebit to make the performance measure less sensitive to investment activities which can be controlled through other contractual terms such as a restriction on capital expenditure and provide empirical evidence consistent with this conjecture

discussion of an economic framework for conservative accounting and bushman and piotroski 2006 abstract we offer an economic framework for generating predictions about the demand for conservative accounting reports we define conservatism as more timely recognition of losses than gains as a result of the costs and benefits of reporting verifiable information by managers and or firms being asymmetric we also discuss bushman and piotroski s interpretation of the speeds of good news recognition and incremental bad news recognition in basu type regressions as separate signals about accounting conservatism finally we suggest avenues for future research that seeks to investigate the links between institutions and contracts and between contracts and conservatism

firm heterogeneity in capital labour ratios and wage inequality author s leonardi marco abstract this paper documents the increasing dispersion of capital labor ratios across firms in the us and provides some empirical evidence of a positive correlation at the two digit industry level between the dispersion of capital labor ratios across firms and residual wage inequality to explain this empirical fact the paper adopts a search model where firms differ in their optimal capital investment the exogenous decline in the relative price of equipment capital makes the distributions of capital labor ratios more dispersed in a frictional labor market this force generates wage dispersion among identical workers ols estimates of the relationship between capital dispersion and the relative price of equipment capital support the main hypothesis of the model

inflow of labour producer services and wage inequality abstract this paper examines the issue of skilled unskilled wage inequality in the shortrun when varieties of producer services are traded it is shown that irrespective of the relative size of income share of capital inflow of neither skilled nor unskilled labour affects skilled unskilled wage inequality however an increase in i the level of competition in the services sector and ii relative price of the varieties of producer services can affect the level of wage inequality

from low quality reporting to financial crises politics of disclosure regulation along the economic cycle abstract this paper examines how financial reporting regulations affect and respond to macroeconomic cycles by exploring a positive framework in which regulators subject to political pressures respond to cyclical demands by borrowers and lenders we establish that as economic conditions initially decline political power shifts toward interest groups favoring less financial transparency what follows is a counter cyclical increase in economic activity as more non reporting loans are financed possibly coincidental with more aggregate uncertainty during a recession reporting quality is increased potentially causing a crisis like adjustment of economic activity to the cycle we also discuss implications for event studies bank lobbying mark to market and cost of capital

swimming upstream trends in the gender wage differential in the 1980s using michigan panel study of income dynamics data for 1979 and 1988 we analyze how a falling gender wage gap occurred despite changes in wage structure unfavorable to low wage workers the decrease is traced to gender specific factors which more than counterbalanced changes in measured and unmeasured prices working against women supply shifts net of demand were unfavorable for women generally and hurt high skilled more than middle and low skilled women by analyzing wages we find support for the notion of a gender twist in supply and demand having its largest negative effect on high skilled women
