stock price reactions as surrogates for the net cash flow effects of corporate policy decisions abstract this paper adopts a rational market structure to examine the link between the cash flow effects of management policy decisions and the resulting stock price reactions the focus is on testing cross sectional associations between cash flow effects and the underlying characteristics of affected firms we find that it is not possible to infer the sign of association between the stock price reaction and any characteristics of the firm that are observable before management announces its decision our methodological suggestions involve exploiting either a priori assumptions or sample information about the probability distribution of unobservable decision variables underlying the management decision process

entrepreneurs risk aversion and dynamic firms how do entrepreneurs vary firm size capital structure and default to manage risk we show that more risk averse entrepreneurs run smaller more highly leveraged firms and default less because running a smaller firm with higher debt reduces personal funds at risk in the firm optimal default depends on ex ante debt consumption forgone from firm liquidation and owner capacity to inject funds we show that entrepreneurs sacrifice current consumption in the hope of future success that never materializes for the bottom 25 percent but entrepreneurship is a path toward great wealth and high consumption for the top quartile

the use of control groups in capital market research capital market researchers have used several different types of control groups in attempting to assess stock market reactions to accounting events in recent years the properties of various control groups have been examined to determine the sensitivity of experimental results to a particular control group gonedes 1975 1978 foster 1980 brown and warner 1980 beaver 1981 except for the brown and warner study these studies have been of an analytical nature the purpose of this study was to extend the brown and warner analysis to four alternative control groups using a particular accounting event study as an example the example involved an assessment of whether the stock market reacted to actual changes in accounting estimates the four types of control groups examined were those which have been used in previous capital market studies see section 3 one of brown and warner s main conclusions was that beyond a simple one factor market model there is no evidence that more complicated methodologies such as risk equivalent control portfolios convey any benefit our results which are based on a market setting typical of many information content studies lead to a potentially different conclusion brown and warner injected simulated market effects into randomized data and by replicating their analyses 250 times they were able to

measuring the default risk of small business loans a survival analysis approach in this paper we report that although medium maturity loans originated under the sba 7 a loan guarantee program are targeted to small firms that fail to obtain credit through conventional channels the default experience is comparable to that of a large percentage of loans held by larger commercial banks we establish that the default behavior of these loans is time sensitive as a loan seasons the likelihood of default increases initially peaks in the second year and declines thereafter using a discrete time hazard framework we show that the likelihood of default is conditional on borrower lender and loan characteristics and changes in economic conditions

bank mergers and small firm financing in this study the effect of bank mergers on the most recent attempt to obtain financing from a sample u s small firms in the mid 1990s is examined banking mergers which affected about 25 of the firms responding to the survey had no significant effect on the ability of small firms to obtain a loan or the contract loan rate on the most recent loan from a commercial bank however the incidence of mergers does appear to increase nonprice loan terms increase the incidence of related fees for services raise the frequency of searching for a new bank and result in deterioration of service quality little evidence is found that the most informationally opaque firms e g the smallest firms bear a higher cost from mergers than do less informationally opaque firms

bad times good credit banks limited knowledge about borrowers creditworthiness constitutes an important friction in credit markets is this friction deeper in recessions thereby contributing to cyclical swings in credit or is the friction reduced as bad times reveal information about firm quality we test these alternative hypotheses using internal ratings data from a large swedish cross border bank and credit scores from a credit bureau the ability to classify corporate borrowers by credit quality is greater during bad times and worse during good times soft and hard information measures both display countercyclical patterns our results suggest that information frictions in corporate credit markets are intrinsically countercyclical and not due to cyclical variation in monitoring effort the presence of countercyclical information frictions provides a rationale for countercyclical provisions or capital in banks to smooth credit cycles

communication in repeated games with private monitoring abstract the paper considers repeated games where each player can be observed by only a subset of the other players and where players can make public announcements about the behavior of the players they observed we address the following question what is the minimal level of observability that is required to obtain efficient outcomes the main result is that the limit set of sequential equilibrium payoffs when the discount factor tends to one contains the set of individual rational payoffs whenever each player is observed by at leasttwoother players journal of economic literatureclassification number c73

stock price reactions to lifo adoptions the association between excess returns and lifo tax savings although long a topic of accounting research little is known about the motives for or effects of voluntary changes in accounting techniques among the motives which have been suggested are attempts by managers to smooth reported earnings gordon 1964 copeland 1968 cushing 1969 white 1972 and ronen and sadan 1981 to influence man agement compensation to reduce regulatory or political costs watts and zimmerman 1978 and to avoid bond covenant restrictions holthausen 1981 while some of these motives may be consistent with a market value rule they often fail to provide unambiguous accounting change predictions e g which accounting changes result in lower regulatory costs moreover empirical verification has been constrained by the unobservability of the variables to which the managers allegedly respond the stock price reaction which should be expected for a given account ing change depends not only on its implications for the valuation of securities but also on the extent to which the implications are already known or anticipated by investors 3 ultimately our ability to detect these stock price effects if any depends on the power of our tests previous studies of the effects of accounting changes have generally not found significant stock price reactions archibald 1972 ball 1972 kaplan and roll 1972 harrison 1977 and holthausen 1981 4 for the most part these studies dealt with accounting changes which had no direct cash flow effects in contrast changes in inventory costing methods especially those involving the last in first out lifo cost flow assumption can generate potentially large changes in a firm s cash flows due to their impact on taxable earnings these cash flow effects provide not only a motive for lifo changes5 which is consistent with the market value rule but also implications for associated stock price effects if investors react to lifo s cash flow implications rather than to its effects on reported earnings then positive stock price adjustments should be associated with lifo adjustments however the evidence from previous studies of stock price reactions to lifo adoptions is inconclusive ball 1972 sunder 1973 1975 abdel khalik and mckeown 1978 brown 1980 and ricks 1982 while several factors may account for these results see section 2 it can be noted that the previous studies have considered only a dichotomous variable whether or not a firm has adopted lifo yet because the cash flow consequences of a lifo adoption decision depend on a number of firm specific factors this approach ignores potentially large differences among firms in the economic consequences of lifo adoptions most firms switching to lifo now reveal in their financial statement disclosures the tax savings which have been realized this study uses these disclosures to examine the association between unsystematic re turns and the magnitudes of first year lifo tax savings for all nyse firms which adopted or extended their use of lifo during the period 1972 80 subject to data availability 6 the research design employs within group comparisons based on cumulative monthly unsystematic excess returns with appropriate controls for unexpected earnings per formance 7 this design avoids several methodological weaknesses inherent in the previous studies and allows more definitive tests of hypotheses relating investor reactions to the income and cash flow effects of lifo adoptions as reported more fully below results based on lifo adoptions made in 1974 are consistent with a positive association between cumulative excess stock returns and the magnitudes of lifo tax savings 8 the results also provide evidence that changes in systematic risk may accompany lifo adoptions however contrary to previous studies most of the sample firms exhibit downward rather than upward changes in systematic risk section 2 reviews the previous studies of stock price reactions to lifo adoptions and suggests explanations for their results section 3 discusses the alternative approach employed in this study while section 4 describes the test methodologies employed the data and data selection procedures are described in section 5 the results and a discussion are presented in section 6 section 7 offers some conclusions

market based empirical research in accounting a review interpretation and extension a decade and a half of the most concerted and ambitious research effort in accounting history is evaluated here it is the search into the relationship between publicly disclosed accounting information and the consequences of the use of this information by the major group of usersequity investors as such consequences are reflected in characteristics of common stocks traded in major exchanges this research effort known as market based accounting research mbar obtained its impetus from major developments in finance theory during the late 1950s and early 1960s these were the portfolio selection theory and its offspring the capital asset pricing model capm and the concept of informationally efficient capital markets ecm subsequent developments in information economics agency theory and optimal incentive signaling models were quickly incorporated into mbar while the impetus to this line of research came from other disciplines accounting was not only a beneficiary but also to a modest extent a benefactor mbar is relevant to the study of capital market efficiency the capm information economics and regulation this contribution distinguishes mbar from most accounting areas whose contributions to other disciplines are negligible in

accounting for retail land sales analysis of a mandated change abstract this study assesses the stock market s reaction to a series of events leading up to a mandated change in accounting for retail land sales evidence is found to support the conclusion that the market reacted to some of these events in a manner consistent with the effects of the accounting change on debt annagement contracts a distinctive aspect of the analysis is the efficient use of security returns data to detect market reactions and to derive empirical distributions of test statistics employed the analysis is extended by a model for grouping regression equations known as seemingly unrelated regressions however the gains from this extension are modest

implementation in differential information economies abstract we consider the problem of implementation of social choice correspondences in differential information economies we provide necessary conditions for implementation and slightly stronger conditions which are sufficient to guarantee implementation

depreciation policy changes tax earnings management and investment opportunity incentives abstract contrary to previous studies we find managers change depreciation policies in predictable ways we identify three dimensions of depreciation policy changes whether it is a method change or an estimate revision whether it is income increasing or decreasing and whether it applies to new assets only or both new and existing assets this disaggregation leads to three findings first a 1981 tax law altered the frequency of estimate revisions and method changes second firms adopting income increasing method changes for all assets experience worse performance than those adopting such changes only for new assets finally non income increasing policy changes are associated with changes in investment opportunities

on the diversification observability and measurement of estimation risk this paper reexamines how risk return relationships are affected by investor uncertainty about the exact parameters of the joint rate of return distribution we attempt to clarify results relating to three central issues first we address the issue of diversification focusing on an apt factor model framework second we discuss the observability of estimation risk and describe research experimental designs that should encompass the existence of estimation risk and reveal it in the data finally we suggest exploiting contemporaneous return observations on high and low information securities to aid in the measurement of return parameters for low information securities

the impact of sfas no 8 on equity prices of early and late adopting firms abstract this study examines the economic consequences of statement of financial accounting standards no 8 sfas no 8 compared to a matched control group both early adopters and late adopters of sfas no 8 exhibited significantly negative excess returns in the exposure draft release period even after adjusting for a size effect in january weighted least squares and ordinary least squares cross sectional regressions were compared the late adopter regressions weakly support contracting and political cost theories

failure of stock prices to discipline managers in a rational expectations economy in this paper we show that even a strongly efficient stock market is by itself insufficient to discipline managers who may hold incorrect beliefs about investors behavior and their decision rules instead of disciplining the managers the stock market may generate prices that reinforce these incorrect beliefs when this happens the disciplining of managers must be accomplished through other mechanisms such as through markets for managerial labor mergers and takeovers the financial press and education these alternative mechanisms may produce slower disciplinary reactions than the stock market several important classes of accounting phenomena seem consistent with a failure of the stock market to discipline managers promptly we present in detail how the apparent failure of managers to make cashflow maximizing lifo fifo choices in a timely fashion is consistent with this theory our approach is also applicable to other financial reporting conundrums in which adverse managerial and stock market reactions were predicted in response to financial accounting standard no 2 accounting for research and development outlays standard no

predisclosure information firm capitalization and security price behavior around earnings announcements several studies on the relationship between earnings reports and security price behavior provide evidence suggesting that a significant portion of the information revealed through earnings reports is reflected in security prices prior to the report month e g ball and brown 1968 and brown and kennelly 1972 this has been attributed at least partly to the existence of other more timely sources of information which allow market agents to forecast earnings prior to their release the evidence above reflects an average finding across all firms one question of interest is whether there are significant systematic crosssectional differences in the security price reactions to earnings announcements of firms which are associated with specific firm characteristics that lead to differential amounts of predisclosure information this study focuses on firm size capitalization as one such characteristic a firm

the economic consequences of accounting choice implications of costly contracting and monitoring abstract in this paper we review research into the economic consequences of voluntary and mandatory choices of accounting techniques and standards we discuss how the predictions of extant economic consequence theories are driven by contracting and monitoring costs associated with management compensation contracts bond covenants regulation and or political visibility we review empirical tests of economic consequence theories categorize those tests and discuss their strengths and weaknesses the empirical tests reveal two systematic associations with accounting choice size a proxy for political visibility and leverage a proxy for contracting and monitoring costs of lending agreements interpretation of the results is difficult due to general limitations of the tests we conclude by suggesting some directions for future research based on our analysis of the potential payoffs associated with different types of empirical tests

risk return and equilibrium a revisit this paper reports the results of tests of the major implications of the two parameter capital asset pricing model the findings indicate that the relationship between stock returns and systematic risk contains important nonlinearities during 1935 82 these nonlinearities cannot be ascribed to previously documented anomalies related to firm size or january seasonality moreover the test results appear to be sensitive to the choice of the proxy for the market portfolio

the magnitudes of financial statement effects and accounting choice the case of the adoption of sfas 87 abstract we examine the accounting choice decision in the context of the timing of adoption of sfas 87 unlike most prior studies we consider interactions between firm characteristics and the magnitudes of the financial statement effects of an accounting decision we expect that including interactions will both enhance the ability to explain accounting choice and facilitate distinction between omitted variables ball and foster 1982 and hypothesized relations results are consistent with these expectations

efficiency results in n player games with imperfect private monitoring abstract we demonstrate that efficiency is achievable in a certain class of n player repeated games with private almost perfect monitoring our equilibrium requires only one period memory and can be implemented by two state automata furthermore we show that this efficiency result holds with any degree of accuracy of monitoring if private signals are hemiindependent whereas most existing research focuses on two player cases or only a special example of n player games our results are applicable to a wide range of n player games of economic relevance such as trading goods games and price setting oligopolies

the turn of the year in canada a number of investigators have reported that january stock returns in the u s exceed returns for other months of the year this paper documents a similar finding for canadian stocks over the period 1951 1980 however canada did not introduce a capital gains tax until 1973 and the paper reports that january returns in canada exceed returns for other months of the year before and after this date thus these data do not support the tax loss selling pressure hypothesis as the entire explanation for the turnof the year effect in stock returns nor by implication do they support the tax lossselling pressure hypothesis as the complete explanation for the small firm effect in u s stocks returns recently keim 9 has reported that returns on nyse and ase firms with small market values exceed by significant margins returns on firms with large market values this result was previously reported by banz 1 and reinganum 11 but keim s analysis shows that most of the excess return for small firms is concentrated in january indeed it is concentrated in the first two weeks in january roll 13 also documents this phenomenon and investigates a number of possible explanations for it 2 after rejecting several possible nonexploitable explanations roll is left with year end tax loss selling pressure of the sort discussed by branch 2 dyl 5 and givoly and ovadia 6 as the most likely explanation of this result according to the tax loss selling pressure hypothesis toward the end of the year stockholders sell stocks that have declined in price during the year investors do this to take advantage of the opportunity to write off capital losses against ordinary income in computing their federal income taxes the year end sell off exerts downward pressure on stock prices as soon as the tax and calendar year ends the selling pressure is relieved and stock prices quickly rebound to their equilibrium levels roll 13 presents some evidence consistent with this hypothesis specifically he finds a negative correlation between stock returns in january and returns over the previous 12 months that is stocks that decrease in value during the year tend to be big gainers in january roll also finds that

business failure of new firms an empirical analysis using a multiplicative hazards model abstract this paper investigates business failure of new firms using a multiplicative hazards model we estimate the determinants of business failure among new manufacturing firms in tokyo during the period 1986 to 1994 it is found that a new firm without sufficient capital or a sufficient size has a higher risk of business failure it is also found that the new firm tends to have more difficulty surviving in an industry characterized by a high entry rate with respect to the timing of entry the new firm that entered just before or after the collapse of the so called bubble economy has been more likely to fail furthermore we estimate a regression model based not only on age but also on calendar time by using a regression model based on calendar time it is found that the firm s age has been related to business failure

beliefs and private monitoring this paper develops new recursive set based methods for studying repeated games with private monitoring for any nite state strategy prole we nd necessary and sucient conditions for whether there exists a distribution over initial states such that the strategy together with this distribution form a correlated sequential equilibrium also for any given correlation device for determining initial states including degenerate cases where players initial states are common knowledge we provide necessary and sucient conditions for the correlation device and strategy to be a correlated sequential equilibrium or in the case of a degenerate correlation device for the strategy to be a sequential equilibrium we also consider several applications in these we show that the methods are computationally feasible show how to construct and verify equilibria in a secret price setting game

determinants of intramethod choice in the oil and gas industry abstract procedural flexibility can have a substantial impact on reported costs revenues expenses and balance sheet valuations until 1978 oil and gas companies had considerable flexibility in applying full cost and successful efforts a unique opportunity to measure the income effect of firms procedural choices occurred when the sec specified the exact procedures that must be followed by oil and gas producers when they account for exploratory and development costs under both the full cost and successful efforts methods in complying with the new rules firms were required to adjust retained earnings retroactively to reflect what it would have been if the new procedures had been in effect all along these retained earnings adjustments provide a measure of the income effect of procedural choices this study shows that economic incentives influence the procedural accounting choices which were made by oil and gas producers the same economic incentives also influence the choice of full cost or successful efforts finally the discriminatory ability of firms economci incentives is most powerful when firms reporting strategies are defined in terms of both choice of accounting methods and procedural applications within those methods

evidence on the effect of bond covenants and management compensation contracts on the choice of accounting techniques the case of the depreciation switch back abstract provisions of bond indenture agreements and management compensation contracts are examined to derive testable implications concerning management s incentives to choose among alternative accounting techniques the hypotheses are subjected to empirical examination by investigating the voluntary change from accelerated to straight line depreciation for financial reporting purposes only the methodology utilized incorporates an expectations model of accounting earnings in an attempt to separate out of the effects of earnings announcements from accounting change announcements which are often concurrent the evidence from both price and non price data is not consistent with the general hypothesis that bond covenants and management compensation contracts are important determinants of the decision to change depreciation techniques five potential explanations for the results are offered

crossovers dividends and the size effect the size effect may have been the result of high stock volatility and low dividend payments suppose an equity market is partitioned into a large stock index and a small stock index and suppose that over a given period of time each of the indexes retains its share of the total market capitalization price volatility will cause some stocks to cross over from one index to the other which will result in higher returns for the small stock index and lower returns for the large stock index dividend payments by large companies could offset the effect of the crossovers but they have historically been insufficient to do so hence the size effect

aggregation of test statistics an evaluation of the evidence on contracting and size hypotheses abstract more powerful tests of a theory of choice of accounting methods and the effect of changes in these choices on equity values are provided the power increase comes from efficiently aggregating results across studies one conclusion is that at least six variables common to more than one study have explanatory power these variables are managerial compensation leverage size risk and constraints on interest coverage and dividends another conclusion is that the posterior probability that the theory taken as a whole has explanatory power is close to one this conclusion includes the effect of variables that only appear in one study

negotiated accounting rules in private financial contracts abstract this paper explores how private contracts tailor gaap and whether tailoring reflects the characteristics of the contracting parties the analysis reveals that contracts of bank and insurance lenders are different with bank agreements closer to public debt tailoring is one of several characteristics associated with insurance lending agreements the extensive tailoring of gaap income in insurance contracts enforces dividend and payout restrictions that are consistent with the interest of long term insurance lenders in contrast bank lenders deal with borrowers default risk by negotiating shorter maturities security sinking funds and loan syndication

relation between market model prediction errors and omitted variables a methodological note a number of accounting studies have examined market model prediction errors to evaluate the share price effects of various events such as voluntary or mandatory accounting changes a common approach is to examine the prediction errors around the event date of a portfolio of potentially affected firms this approach has been extended recently through the use of cross sectional regressions e g leftwich 1981 holthausen 1981 collins rozeff and dhaliwal 1981 sepe 1982 and chow 1983 in which prediction errors or raw returns are regressed on firm specific variables such as size the purpose of this paper is to examine the implications of some recent findings in finance for the various finance based empirical accounting studies in general two types of omitted variables from the standard capital assets pricing model have been identified first several studies have reported that certain firm specific variables such as size banz 1981 and reinganum 1981 earnings yield basu 1975 1983 and dividend payout ratio litzenberger and ramaswamy 1979 may be omitted variables from the standard capm in addition other studies have found some special time series characteristics of stock returns such

accounting conservatism and managerial risk taking corporate acquisitions abstract watts 2003 and ball and shivakumar 2005 argue that accounting conservatism decreases managerial incentives to make negative net present value investments i develop and test a new hypothesis that accounting conservatism is associated with managers making less risky investments i find that under more conservative accounting managers make less risky acquisitions and that firms with accounting based debt covenants drive this association this result is consistent with conservative firms avoiding risky investments because of the potential for large losses to trigger debt covenants conservatism reducing risk shifting can in part explain debt holders demand for conservative accounting

taxes and stock return seasonality evidence from the london stock exchange prior to the introduction of capital gains taxes seasonality is not detected in the returns of firms that traded on the london stock exchange however after the imposition of a capital gains tax the british stock return data exhibit apparent monthly effects in both jan uary and april additional analysis reveals that while the april effect is consistent with the tax loss selling hypothesis the january effect cannot be attributed solely to the introduction of capital gains taxation furthermore the authors efforts indicate that much caution should be exercised when interpreting studies that compare results from non u s data sources with those from u s data copyright 1987 by the university of chicago

high yield bond default and call risks this paper empirically investigates high yield bond default and call behavior using a competing risks hazard model that simultaneously estimates the impact of bond age issue specific characteristics and business conditions on both events results reveal nonmonotonic aging effects default rates increase and then drop while call rates first increase and then level off rating and coupon size affect default risk while maturity and issue size impact only call rates defaults are more likely when economic conditions have worsened and no improvement is anticipated calls are more likely when interest rates have decreased but are expected to rise

misspecification of capital asset pricing this study documents empirical anomalies which suggest that either the simple one period capital asset pricing model capm is misspecified or that capital markets are inefficient in particular portfolios based on firm size or earnings price e p ratios experience average returns systematically different from those predicted by the capm furthermore the abnormal returns persist for at least two years this persistence reduces the likelihood that these results are being generated by a market inefficiency rather the evidence seems to indicate that the equilibrium pricing model is misspecified however the data also reveals that an e p effect does not emerge after returns are controlled for the firm size effect the firm size effect largely subsumes the e p effect thus while the e p anomaly and value anomaly exist when each variable is considered separately the two anomalies seem to be related to the same set of missing factors and these factors appear to be more closely associated with firm size than e p ratios

robustness of public equilibria in repeated games with private monitoring a repeated game with private monitoring is close to a repeated game with public monitoring or perfect monitoring when i the expected payoff structures are close and ii the informational structures are close in the sense that private signals in the private monitoring game can be aggregated by some public coordination device to generate a public signal whose distribution is close to the distribution of the public signal in the public monitoring game we provide a sufficient condition for the set of uniformly strict perfect public equilibria for a public monitoring game to be robust in nearby private monitoring games in the sense that they remain equilibria with respect to the public signal that is generated by such public coordination devices with truthful reporting our sufficient condition requires that every player is informationally small in a well defined sense

the association between accounting earnings and security returns for large and small firms abstract the differential information hypothesis advanced by atiase 1980 states that information production and dissemination by private parties for the purpose of identifying mispriced securities is an increasing function of firm size this study examines two corollaries of that hypothesis first security prices of large firms anticipate accounting earnings earlier than security prices of small firms second for a given level of unexpected earnings the cumulative abnormal returns of small firms exceed those of large firms the results are generally consistent with atiase s hypothesis

determinants of the corporate decision to capitalize interest abstract until 1974 firms could choose within gaap to capitalize or expense interest costs associated with capital expenditures the predominant practice had been to treat interest as a period expense however in 1974 the securities and exchange commission imposed a moratorium on further adoption of interest capitalization by non regulated firms this study empirically examines economic factors potentially influencing firms decisions to expense or capitalize interest prior to the sec moratorium we hypothesize that the choice may be affected by 1 the existence of management compensation agreements tied to reported earnings 2 debt covenant constraints and 3 the political costs for some firms of reporting higher earnings when compared to the control group our findings are that 1 the frequency of explicit management compensation packages was not greater for the interest capitalization group 2 firms with financial ratios closer to likely debt agreement constraints on dividends interest coverage and leverage tended to elect interest capitalization and 3 other than the largest firms in the politically sensitive petroleum refining industry the larger firms were more likely to capitalize interest

does the classic microfinance model discourage entrepreneurship among the poor experimental evidence from india do the repayment requirements of the classic microfinance contract inhibit investment in high return but illiquid business opportunities among the poor using a field experiment we compare the classic contract which requires that repayment begin immediately after loan disbursement to a contract that includes a two month grace period the provision of a grace period increased short run business investment and long run profits but also default rates the results thus indicate that debt contracts that require early repayment discourage illiquid risky investment and thereby limit the potential impact of microfinance on microenterprise growth and household poverty jel a21 g32 i32 l25 l26 o15 o16

analyzing the length of welfare spells abstract this paper studies the determinants of the length of individual spells of welfare focusing on how the length of a spell affects the probability of its termination the analysis utilizes six years of monthly data on time spent in the afdc program among female household heads a variety of duration dependence models are estimated monthly afdc participation does not show strong evidence of duration dependence two distinct groups appear to utilize welfare one with a very low and constant probability of leaving welfare and a second group which is more affected by time on the program

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

communication in repeated games with imperfect private monitoring this paper examines repeated games in which each player observes a private and imperfect signal on the actions played and in which players are allowed to communicate using public messages providing incentives for players to reveal their observations generates revelation constraints that combined with signal imperfections may be a source of inefficiencies however by delaying the revelation of their observations players may economize on the cost of deterring deviations and thereby avoid these inefficiencies because a player would not want to trigger a sanction that would penalize him too revelation constraints also tend to make sanctions difficult to enforce however with at least three players detecting deviations may not require that all the players reveal their observations in that case we obtain a nash threat version of the folk theorem with two players we do not obtain a similar result nevertheless we show that an efficient outcome can almost always be approximated

cross sectional association between abnormal returns and firm specific variables abstract abnormal returns market model prediction errors are the subject of many event studies in accounting and finance literature conditional on the event of interest researchers have recently used cross sectional regressions to examine relations between abnormal returns and firm specific variables this paper demostrates that non constant variences and covariances in market model residuals across firms introduced bias in the estimated slope coefficients of the independent variables i e the expected signs of the estimated slope coefficients can be predicted a priori a method is develope to removed the bias in the estimated slope coefficiets and is found to be effective this method explicitly takes the dependence among abnormal returns across firms into account methods that assume abnormal returns across firms to be independent do not control for such bias

on cross sectional analysis in accounting research abstract this paper examines cross sectional analysis procedures common to many market based accounting research papers both the economic and econometric properties of levels and returns studies are discussed topics covered include the relations between the accounting studies and cash flow valuation models the role of expectations of accounting variables deflators spurious inference risk adjustment and its relation to growth size and leverage residual dependence dependence among explanatory variables and the effect of scale differences across firms major conclusions are that market value is the correct deflator in returns studies and that levels and returns studies are economically but not econometrically equivalent

mandated accounting changes and debt covenants the case of oil and gas accounting abstract the relationships among mandated accounting changes bond covenants and security prices has been the focus of several studies these studies have provided mixed evidence on the existence of a bond covenant effect on security prices this paper suggests that inconclusive prior results are a consequence of inappropriately measuring the default risk of debt using an option pricing framework it is shown that the debt to equity alone is not an adequate measure of default risk in particular both the debt to equity ratio and the total risk of the firm are necessary to adequately model the bond covenant effects of an accounting change these theoretical propositions are supported by the empirical analysis of the security market reaction to changes in oil and gas accounting

a robust folk theorem for the prisoner s dilemma we prove the folk theorem for the prisoner s dilemma using strategies that are robust to private monitoring from this follows a limit folk theorem when players are patient and monitoring is sufficiently accurate but private and possibly independent any feasible individually rational payoff can be obtained in sequential equilibrium the strategies used can be implemented by finite randomizing automata journal of economic literature classification numbers c72 c73 d82

the effects of debt covenants and political costs on the choice of accounting methods the case of accounting for r d costs abstract until 1974 firms could capitalize or expense all or part of their research and development r d costs managerial choice between these two alternatives is hypothesized to be affected by the existence of debt covenants which employ accounting numbers relating to leverage interest coverage and ability to pay dividends in addition the use of public versus private debt is hypothesized to affect the accounting choice due to differential renegotiation costs lastly a political cost hypothesis is tested this study uses a multivariate statistical technique the generalized jackknife the results suggest that firms which capitalized r d costs were more highly levered used more public debt were closer to dividend restrictions and were smaller than firms which expensed r d costs

forecasting bankruptcy more accurately a simple hazard model i argue that hazard models are more appropriate than single period models for forecasting bankruptcy single period models are inconsistent while hazard models produce consistent estimates i describe a simple technique for estimating a discrete time hazard model i find that about half of the accounting ratios that have been used in previous models are not statistically significant moreover market size past stock returns and idiosyncratic returns variability are all strongly related to bankruptcy i propose a model that uses both accounting ratios and market driven variables to produce out of sample forecasts that are more accurate than those of alternative models copyright 2001 by university of chicago press

evidence of the impact of mandatory changes in accounting principles on corporate loan agreements abstract the theory in this paper predicts that mandatory changes in accounting princples can affect the measurement rules defined in restrictive covenants in firms lending agreements consequently those mandatory changes can have an impact on the value of a firm s equity even if the changes appear to be merely cosmetic this contracting cost theory is tested by examining of both event related and cross sectional abnormal performance of the equity of a sample of firms when the accounting princples board changes accounting princples for business combinations the theory provides at best in incomplete explanation of the observed abnormal performance

the effect of owner versus management control on the choice of accounting methods abstract this paper examines the relationship between the ownership control status of firms and the accounting methods they adopt the arguments of watts and zimmerman s positive theory are integrated with those of managerial economists to generate the prediction that management controlled firms are more likely than owner controlled firms to adopt accounting methods which increase reported earnings this prediction is inconsistent with fama s hypothesis that the market for managerial talent will prevent management controlled firms from acting differently than owner controlled firms this paper compares the depreciation methods used by a sample of management and owner controlled firms for financial reporting purposes the comparison considers and controls for the factors of firm size leverage and the depreciation method used for tax reporting purposes the comparison reveals that there is a significant difference in the depreciation methods adopted by management controlled and owner controlled firms for financial reporting purposes

a limit characterization of belief free equilibrium payoffs in repeated games abstract the present paper studies repeated games with private monitoring and characterizes the set of belief free equilibrium payoffs in the limit as the discount factor approaches one and the noise on private information vanishes contrary to the conjecture by ely et al j c ely j horner w olszewski belief free equilibria in repeated games econometrica 73 2005 377 415 the equilibrium payoff set is computed by the same formula no matter how many players there are as an application of this result a version of the folk theorem is established for n player prisoner s dilemma games

perfect communication equilibria in repeated games with imperfect monitoring this paper introduces an equilibrium concept called perfect communication equilibrium for repeated games with imperfect private monitoring this concept is a refinement of myerson s myerson r b 1982 optimal coordination mechanisms in generalized principal agent problems j math econ 10 67 81 communication equilibrium a communication equilibrium is perfect if it induces a communication equilibrium of the continuation game after every history of messages of the mediator we provide a characterization of the set of corresponding equilibrium payoffs and derive a folk theorem for discounted repeated games with imperfect private monitoring

economic consequences of firms depreciation method choice evidence from capital investments abstract this study identifies several interrelated reasons why firms depreciation method choice is likely to influence managers capital investment decisions we find that firms that use accelerated depreciation make significantly larger capital investments than firms that use straight line depreciation further we find that there has been a migration away from accelerated depreciation to straight line depreciation over the past two decades firms that make such accounting changes make smaller capital investments in the post change periods than in the pre change periods these results suggest that a choice made for external financial reporting purposes influences managers capital investment decisions

debt covenants and accounting choice abstract in this issue duke and hunt and press and weintrop show that leverage is significantly related to the existence of and closeness to accounting based debt covenants alternative rationales for this relation are presented the theory requires more rigorous specification to define closeness to covenants and determine which measure of leverage produces a more appropriate proxy for closeness to covenants then healy and palepu investigate a sample of firms close to their dividend restriction and find in general they are no more likely than other firms to change accounting methods their sample selection criteria reduces the generalizability of their results

an approach to statistical inference in cross sectional models with security abnormal returns as dependent variable several recent event studies test hypotheses about the association between event related abnormal security returns and firm characteristics using a three step procedure first forecast model parameters are estimated usually parameters of a market model second prediction errors or residuals are computed over an event period third prediction errors are regressed cross sectionally on firm characteristics hypothesized to influence the impact of the event on share values results of these regressions are used to draw inferences about the relation between abnormal returns and firm characteristics researchers who employ three step procedures acknowledge that crosssectional ols regressions lead to valid inferences if the disturbances are iid normal in cross section see for example leftwich 1981 p 23 and lustgarten 1982 p 138 while sufficient assumptions to draw valid inferences from ols regressions are clear these assumptions are violated if there is cross correlation and cross sectional heteroscedasticity in the firm return processes from which the prediction errors are estimated assumptions about the processes generating these prediction

cost of capital to the hospital sector this paper provides estimates of the cost of equity and debt capital to for profit and non profit hospitals in the u s for the years 1972 83 the cost of equity is estimated using alternatively the capital asset pricing model and arbitrage pricing theory we find that the cost of equity capital using either model substantially exceeded anticipated inflation the cost of debt capital was much lower accounting for the corporate tax shield on debt and capital paybacks by cost based insurers lowered the net cost of capital to hospitals

taxes and firm size abstract firm size has been used as a proxy for the firm s political costs and hence managers proclivity to choose income reducing accounting procedures this study provides additional evidence on this topic by examining the association between firm size and effective corporate tax rates the latter are one component of a firm s political costs the roughly fifty largest u s exchange listed firms in particular oil and gas companies and manufacturing firms have significantly higher worldwide tax rates than other firms these higher tax rates are observed primarily after the implementation of the u s 1969 tax reform act and after the opec countries raised their tax rates on u s oil producers the findings which are insensitive to alternative sources of data alternative measures of firm size and alternative measures of effective tax rates are consistent with the use in previous studies of firm size as a proxy for the firm s political costs

repeated games with private monitoring two players we investigate two player infinitely repeated games where the discount factor is less than but close to unity monitoring is private and players cannot communicate we require no condition concerning the accuracy of players monitoring technology we show the folk theorem for the prisoners dilemma with conditional independence we also investigate more general games where players private signals are correlated only through an unobservable macro shock we show that efficiency is sustainable for generic private signal structures when the size of the set of private signals is sufficiently large finally we show that cartel collusion is sustainable in price setting duopoly

the effect of accounting procedure changes on ceos cash salary and bonus compensation abstract this paper examines the effect of accounting procedure changes on cash salary and bonus compensation to ceos we estimate whether there is an adjustment to the statistical relation between compensation and corporate earnings following changes that lower earnings fifo to lifo inventory valuation and that raise earnings accelerated to straight line depreciation the results indicate that 1 subsequent to these changes salary and bonus payments are based on reported earnings rather than earnings under the original accounting method and 2 the potential compensation effect of the changes is small compared to the effect of economy or industry wide changes in compensation

impact of state exemption laws on small business bankruptcy decision 1 introductionsmall businesses are a primary source of employment in the u s economy employing over half of the private sector workforce small businesses are responsible for about two thirds of all net new jobs created according to the 2002 small business economic indicators sbei 1 over 99 7 of the 5 7 million firms in the united states are classified as small to medium sized businesses hence small businesses are a substantial contributor to economic growth in the united states small business owners enjoy more flexibility and freedom to capitalize on profitable opportunities than their larger business competitors hence they challenge the larger firms to be more efficient which is ultimately beneficial to consumers unfortunately small and medium sized businesses have a very low survival rate sbei 2002 in 2002 on the heels of the 2001 recession there were 550 100 small business births and 584 500 small business terminations both academics and public policy analysts have become increasingly concerned about the success of small businesses recently there has been a surge in small business research particularly surrounding small business credit supply and demand not surprisingly much of the literature has been focused on changes in lending technologies relationship2 versus scored3 information processing technologies soft versus hard 4 loan size considerations 5 and loan type considerations6 as they relate to small business supply and demand however very few have actually examined why small and medium sized businesses have very low survival rates some studies have analyzed the sensitivities of small business administration sba guaranteed loans to macroeconomic changes industry risks maturity structures 3 7 and 15 year maturities as well as lender and debt characteristics e g glennon and nigro 2001 2002 dunsky and pennington cross 2003 meanwhile agarwal chomsisengphet and liu 2003 empirically assessed the significant importance of owner and firm characteristics in determining the risk of small business default while controlling for the macroeconomic and industry risks with bankruptcy filings continuing to rise significantly in recent years many policy makers are turning their attention to bankruptcy laws specifically congress is considering reforming personal bankruptcy laws that if passed will significantly impact the demand for and supply of both consumer credit and small business funding white 2001 concludes that this bankruptcy reform could potentially reduce small business ownership but increase the supply of small business credit and in turn affect the growth of the u s economy small business owners have an incentive to file for personal bankruptcy when their indebtedness exceeds the value of their assets because both their personal and business debts can be discharged 7 though the bankruptcy exemption law is primarily designed for consumers the personal bankruptcy exemption law is a de facto bankruptcy procedure for small business owners because the debt of a noncorporate firm is the personal liability of the entrepreneur owner fan and white 2003 hence investigating the potential impact of the exemption law on small business bankruptcy decisions may provide some insight into how the bankruptcy laws should be reformed further fan and white 2003 argue that while the expected return to creditors should be lower in states with higher exemption level upon small business shutdown it is not entirely clear whether lenders will actually shut down a financially troubled small business while they empirically find that small businesses in high exemption states are more likely to be shut down this positive relationship is statistically insignificant the authors conclude that additional research will be needed to determine if a significant relationship exists p

transaction costs and asset prices a dynamic equilibrium model in this article we study the effects of transaction costs on asset prices we assume an overlapping generations economy with a riskless liquid bond and many risky stocks carrying proportional transaction costs we obtain stock prices and turnover in closed form surprisingly a stock s price may increase in transaction costs and a more frequently traded stock may be less adversely affected by an increase in transaction costs calculations based on the marginal investor overestimate the effects of transaction costs for realistic parameter values transaction costs have very small effects on stock prices but large effects on turnover

survey evidence on diffusion of interest and information among investors abstract questionnaire surveys of institutional and individual investors were undertaken to learn about patterns of communications it was found that direct interpersonal communications are very important in investor decisions questions elicited what fraction of investors were unsystematic and allowed themselves to be influenced by word of mouth communications or other salient stimuli randomly sampled investors were studied as well as investors in stocks whose price had recently increased dramatically contagion or epidemic models of financial markets are proposed in which interest in individual stocks is spread by word of mouth the survey evidence is interpreted as supporting such models

an income strategy approach to the positive theory of accounting standard setting choice abstract this paper is designed to provide additional evidence on the positive theory of accounting policy choice by combining individual accounting principles into firm income strategies these strategies were the dependent variable in a probit analysis where the independent variables were size management compensation industry concentration ratio systematic risk capital intensity and the total debt to total asset ratio the results indicate that four of these factors size management compensation concentration ratio and the total debt to total asset ratio have a significant association with the choice of a firm s income strategy this test provides strong evidence consistent with the positive theory of accounting standard setting choice we also present evidence that smaller firms and or firms in less concentrated industries do not appear to make accounting policy choice decisions that are consistent with this theory

the economic determinants of the market reaction to proposed mandatory accounting changes in the oil and gas industry a cross sectional analysis abstract this paper examines the economic reasons for the observed negative abnormal common stock performance of firms whose reported earnings and stockholders equity were negatively affected by the proposed elimination of full cost accounting in the oil and gas industry four explanations of the market effects of this mandatory accounting change are examined 1 naive investor theory 2 modified naive investor theory 3 contracting cost theory and 4 estimation risk theory these hypotheses are developed in detail and used to generate variables for a cross sectional model which explains observed return behavior the effect of the accounting change on total stockholder s equity the existence of financial contracts denominated in terms of accounting numbers and to a lesser extent firm size are shown to be important explanatory variables the importance of these variables is consistent with both the contracting cost and estimation risk theories

does it pay to change your company s name a stock market perspective a company s name is commonly considered to be an integral part of its image just like the quality of its products or the quality of its technical services changing a company s name is a major policy decision contemplated by many firms and actually implemented by some each year this paper attempts to examine albeit indirectly whether a name change can improve the profit performance of a firm and what type of firm is more likely to succeed in doing so we use the event study methodology developed in finance to examine the above questions with respect to 58 corporations that changed their names in 1981 1985 our findings are that for most of the firms name changes are associated with improved performance and that the greatest improvement tends to occur in firms that produce industrial goods and whose performance prior to the change was relatively poor evidence that industrial good producers are also heavy users of corporate advertising lends further credence to this finding our findings do not support however the contention that the new name per se will enhance demand for the firm s products rather it seems that the act of a name change serves as a signal that other measures to improve performance such as changes in product offerings and organizational changes will be seriously and successfully undertaken the rationale behind why such a signal is sent and why it is believed is discussed

arbitrage short sales and financial innovation the authors describe a model of general equilibrium with incomplete markets in which firms can innovate by issuing arbitrary costly securities when short sales are prohibited firms behave competitively and equilibrium is efficient when short sales are allowed these classical properties may fail if unlimited short sales are allowed imperfect competition may persist even when the number of potential innovators is large if limited short sales are allowed perfect competition may obtain in the limit but equilibrium can be inefficient because of the presence of an externality the private benefits of innovation for firms differ from the social benefits copyright 1991 by the econometric society

belief based equilibria in the repeated prisoners dilemma with private monitoring abstract we analyze repeated prisoners dilemma games with imperfect private monitoring and construct mixed trigger strategy equilibria such strategies have a simple representation where a player s action only depends upon her belief that her opponent s are continuing to cooperate when monitoring is almost perfect the symmetric efficient outcome can be approximated in any prisoners dilemma game while every individually rational feasible payoff can be approximated in a class of such games the efficiency result extends when there are more than two players it requires that monitoring be sufficiently accurate but does not require very low discounting when a public randomization device is available journal of economic literature classification numbers c73 d82

the benefits of lending relationships evidence from small business data this paper empirically examines how ties between a firm and its creditors affect the availability and cost of funds to the firm we analyze data collected in a survey of small firms by the small business administration the primary benefit of building close ties with an institutional creditor is that the availability of financing increases we find smaller effects on the price of credit attempts to widen the circle of relationships by borrowing from multiple lenders increases the price and reduces the availability of credit in sum relationships are valuable and appear to operate more through quantities rather than prices

informational size and incentive compatibility we examine a general equilibrium model with asymmetrically informed agents the presence of asymmetric information generally presents a conflict between incentive com patibility and pareto efficiency we present a notion of informational size and show that the conflict between incentive compatibility and efficiency can be made arbitrarily small if agents are of sufficiently small informational size the incompatibility of pareto efficiency and incentive compatibility is a central theme in economics and game theory the issues associated with this incompatibility are particularly important in the design of resource allocation mechanisms in the presence of asymmetrically informed agents where the need to acquire information from agents in order to compute efficient outcomes and the incentives agents have to misrepresent that information for personal gain come into conflict despite a large literature that focuses on these issues there has been little work aimed at understanding those situations in which informational asymmetries are quantitatively important virtually every transaction is characterized by some asymmetry of information any investor who buys or sells a share of stock generally knows something rel evant to the value of the share that is not known to the person on the other side of the transaction in order to focus on more salient aspects of the problem many models rightly ignore the incentive problems associated with informa tional asymmetries in the belief that for the problem at hand agents are infor mationally small however few researchers have investigated the circumstances under which an analysis that ignores these incentive problems will yield results similar to those obtained when these problems are fully accounted for in this paper we study a class of mechanism design problems our goal is to formalize informational size in a way that when agents are informationally small 1 early versions of this paper circulated under the titles informational smallness and pareto effi ciency and informational smallness and incentive compatibility we thank jacques cremer dean foster andreu mas colell stephen morris david schmeidler and particularly faruk gul for help ful conversations and rajiv vohra for a very careful reading we also thank the numerous partici pants in seminars at which this paper was presented for helpful comments we also thank an editor and the referees for very helpful comments and thank ichiro obara for pointing out an error in an earlier version postlewaite gratefully acknowledges support from the national science foundation

options short sales and market completeness this paper presents empirical evidence that trading in options contributes to both transactional and informational efficiency of the stock market by reducing the effect of constraints on short sales the significantly higher average level of short interest exhibited by optionable stocks supports the argument that options facilitate short selling we also find significant effects on option prices related to the short interest in the underlying stock we then present evidence that options also increase information efficiency earlier work that is replicated and extended here has suggested that short sale constraints cause stock prices to underweight negative information options appear to reduce that effect

the repeated prisoner s dilemma with imperfect private monitoring abstract in this paper i study a repeated prisoner s dilemma game in which monitoring is private and imperfect a partial folk theorem is proved for the case of almost perfect monitoring

the sec reversal of fasb statement no 19 an investigation of information effects it has become popular in recent years to assess the economic consequences of new financial reporting standards and disclosure requirements as reflected in stock price behavior while the motivation for such studies seems to be generally accepted there are serious problems both in designing studies to assess the capital market reaction to new accounting rules and in subsequently interpreting the results for policymaking the difficulties are largely due to the lack of tight models of how new financial accounting standards board fasb standards and securities and exchange commission sec releases should impact investor decisions within the context of efficient markets this generally leads the researchers to test for average abnormal stock returns upon the announcement of a new accounting rule across a sample of firms subject to the rule this empirical approach is exposed to two major dangers first the intrusion of confounding events can easily lead to rejection of the null hypothesis of no price response due to both the very general nature of the alternate hypothesis of average abnormal returns and the single event date

the folk theorem for repeated games with observation costs abstract the folk theorem literature has been relaxing the assumption on how much players know about each other s past action here we consider a general model where players can buy precise information every period each player decides whether to pay a cost to accurately observe the actions chosen by other players in the previous period when a player does not pay the cost he obtains only imperfect private signals observational decisions are unobservable to others known strategies such as trigger strategies do not work since they fail to motivate players to pay for information this paper shows that the folk theorem holds for any level of observation costs unlike existing folk theorems with private monitoring ours imposes virtually no restriction on the nature of costless imperfect signals the theorem does not use explicit or costless communication thereby having implications on antitrust laws that rely on evidence of explicit communication the main message is that accurate observation alone however costly enables efficient cooperation in general repeated games

efficiency in repeated prisoner s dilemma with private monitoring abstract this paper analyzes repeated games with private monitoring where in each period each player receives a signal of the other player s action in the previous period and that signal is private information previous literature on discounted repeated games with private monitoring has not shown whether or not nearly efficient equilibria exist for a repeated prisoner s dilemma satisfying a certain assumption regarding stage game payoffs we show that there exists a nearly efficient sequential equilibrium provided that imperfectness of signals is small and players are patient journal of economic literature classification number c73
