investor preference for large firms new evidence on economies of size in the last several decades industrial organization literature has been replete with studies demonstrating a systematic relationship between accounting rates of return and firm size in the direction of greater and more stable accounting profits for larger firms these studies have been subject to criticism for an alarming number of statistical and conceptual problems the most important of which alleges a serious bias in accounting profit measures as proxies for economic profit 2 the criticisms have resulted in a stalemate in the interpretation of empirical evidence on firm size and performance nevertheless there is continued interest in the area ostensibly resulting from policy concerns with large firm advantages in both product and capital markets this paper provides new evidence concerning the industrial organization literature controversy of the connection between firm size and performance stock market data are used to examine the relationship between capital market returns risk and firm size the findings suggest that even if there were no advantages of large size in the product market equal rates of operating profit large firms would still have a substantial capital raising advantage over small firms this advantage is unrelated to the widely recognized floatation cost economies even after controlling for nondiversifiable risk using the capital asset pricing model capm investors still demonstrate a statistically significant and economically important preference for the securities of larger firms investors apparently place a premium on large firms which is not attributable to large firms observed lower risk as captured by the widely used measure of nondiversifiable risk beta risk this finding a fresh contribution to the

job mobility and earnings instability there is still no consensus on the causes of the increase in the variance of transitory earnings earnings instability in the united states it is difficult to attribute the rise in instability to job mobility because there is no evidence of a concurrent increase in job turnover or separations using an error component model of the covariance structure of earnings on panel survey of income dynamics and survey of income and program participation data this study shows that job mobility and the increase in the variance of wage changes upon job change accounts for a substantial part of the increase in earnings instability the empirical evidence is consistent with the simulations of a search and matching model where an increase in the variance of productivity shocks increases on the job search and earnings instability among job changers while leaving job turnover approximately constant jel j21 j31

empirical evidence on dividends as a signal of firm value the role of dividends in firm valuation continues to be a theoretical puzzle as well as an empirical obsession with economists the pioneering work by modigliani and miller mm 32 29 is the archetype of the theoretical dilemma whereas the authors proved convincingly the irrelevance of dividend policy to firm value within a perfect capital market they tempered their irrelevance proposition with what is usually referred to as the information content of dividends icd hypothesis in a more scientific sense this hypothesis should be labeled as a conjecture since it is essentially an ad hoc observation that dividends may convey information to the capital market concerning a firm s future earnings potential even though the icd hypothesis was not derived from a well specified economic model it has nevertheless been subjected to a plethora of empirical studies in general these studies have focused upon the precise influence of dividend changes upon a firm s common stock price overall the results can be described as being supportive of the notion that stock price movements are positively correlated with cash dividend changes this correlation of course is consistent with the icd hypothesis

the mispricing of u s treasury bonds a case study this article documents an apparent pricing anomaly involving 94 percent 30 year treasury bonds during the months of may and june 1986 during this period the price of the 94s rose sharply relative to the prices of other long term treasury bonds and created a potential arbitrage opportunity in addition owners of the 94 bonds were able to borrow at a zero interest rate bypledging their bonds detailed examination reveals that this relative pricing anomaly cannot be attributed to changes in the level or term structure of interest rates or to differences between the bonds with respect to liquidity taxation or duration

can tax loss selling explain the january seasonal in stock returns this paper analyzes the tax loss selling hypothesis as an explanation of the january seasonal in stock returns and argues that rational tax loss selling implies little relation between the january seasonal and the long term loss empirical results show that the january seasonal is as strongly related to the long term loss as it is to the short term loss the evidence is inconsistent with a model that explains the january seasonal by optimal tax trading

return seasonality in stocks and their underlying assets tax loss selling versus information explanations results of tests contrasting tax loss selling with intertemporal information variation as explanations of the january seasonal in stock returns are reported closed end fund shares display the typical size related january seasonal while their net asset values do not interpreting the net asset value return as a proxy for information about underlying assets this result indicates information variation is not a necessary condition for the january effect in stocks the share returns at the turn of the year are negatively related to their mean preceding year returns and positively related to the standard deviations of their preceding year returns these results are consistent with tax loss selling article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

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

size seasonality and stock market overreaction recent research finds that the prior period s worst stock return performers losers outperform the prior period s best return performers winners in the subsequent period this potential violation of the efficient markets hypothesis is labeled the overreaction phenomenon this paper shows that the tendency for losers to outperform winners is not due to investor overreaction but to the tendency for losers to be smaller sized firms than winners when losers are compared to winners of equal size there is little evidence of any return discrepancy and in periods when winners are smaller than losers winners outperform losers

the evolution of high incomes in northern america lessons from canadian evidence this paper uses tax statistics to construct new series on canadian top income shares from 1920 to 2000 and provides a systematic comparison with the u s experience as in the united states top income shares in canada display a ushaped pattern over the century with a precipitous drop during world war ii followed by a slower decline until 1970 since the late 1970s top income shares have been increasing dramatically and the very top shares are now as high as in the pre war era as in the united states the recent increase in top income shares is the consequence of a surge in top wages and salaries the canadian experience since the late 1970s does not appear to be well explained by tax changes suggesting that the upward trend in canada derives from the united states perhaps because many high income canadians have an emigration option this in turn suggests that the recent increase in u s personal income top shares is not merely a change in tax reporting behavior the recent sharp increase in top income shares in canada is of the same magnitude at the individual and family level and is not due to an increase in income mobility

portfolio rebalancing and the turn of the year effect this paper finds that for the 1935 1986 period the market s risk return relation does not have a january seasonal the findings differ from those of other studies due to the use of value weighted rather than equally weighted portfolios inferences are sensitive to the weighting procedure because of the small firm return patterns in january in particular even in those januaries for which the market return is negative small firm returns are positive and they are more positive the higher is beta this is consistent with the portfolio rebalancing explanation of the turn of the year effect since at least 1926 the average return on small firms in january has been unusually high a phenomenon known as the turn of the year effect in this paper we present new evidence regarding the risk return characteristics of small firms in january we find that for small firms there is a positively sloped riskreturn relation in both up and down markets this pattern is difficult to reconcile with the belief that the high return on small firms in january is equilibrium compensation for risk bearing we show how these patterns in small firms returns have led others to conclude that the market s risk return relation has a january seasonal in particular rozeff and kinney 21 and tinic and west 22 23 among others using equally weighted portfolios formed on the basis of historical betas have found a steeper slope for the capm s risk return relation in january than in other months we demonstrate that this pattern exists only for small firms consequently statistical inferences about the risk return relation are heavily dependent upon whether equally weighted or value weighted portfolio returns are used in the estimation we show that for 1935 86 when monthly cross sectional regressions are estimated using value weighted portfolio returns there is no more of a statistically significant difference in the estimated return to risk bearing in january than in the other eleven months of the year the notion that there is a january seasonal in the capm s risk return relation for the us has rapidly become accepted knowledge for example corhay hawawini and michel 6 accept this conclusion and investigate whether other

fundamental analysis and subsequent stock returns abstract this paper re examines the ou and penman 1989 conclusion that fundamental analysis identifies equity values not currently reflected in stock prices and thus systematically predicts abnormal returns their fundamental summary measure pr the estimated probability of an earnings increase also proxies for firm size and capm risk after controlling cross sectional differences in capm beta and firm size no significant incremental predictive ability is attributable to pr the pr measure is interpreted as a proxy for expected return differences rather than as new evidence of a systematic market underreaction to the future earnings signal inherent in current financial statements

estimation risk and stability of optimal portfolio composition abstract the mean variance portfolio models indicate that for optimal investment decisions the true ex ante values of the model parameters should be used instead in practice ex post parameter estimates are used if in the estimation process the probability distribution of estimators is not known there is a problem of estimation risk this paper investigates the impact of estimation risk on the composition of optimal portfolios as the multivariance distribution of the vector of optimal portfolio weights allocated to risky assets is analytically intractable a use of the monte carlo simulation experimental is made this study suggests that the composition of optimal portfolio is relatively more stable when the estimates of model parameters are obtained from longer series of historical observations or the expected portfolio return is low

agricultural support policies in imperfectly competitive markets why market power matters in policy design most agricultural policy analysis assumes that markets are perfectly competitive despite increasing evidence to the contrary we demonstrate that the interaction of market power and government intervention may lead to outcomes that are counter to key results of policy analysis for perfectly competitive markets we show that market power may reduce or eliminate entirely the net welfare benefits from removing two traditional support mechanisms price floors and deficiency payments and may increase considerably the government s cost of implementing either of them accordingly optimally designed price support measures may improve welfare in the presence of downstream oligopoly and or oligopsony power copyright 2011 oxford university press

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

variance and lower partial moment betas as bases for costing equity capital among regulated utilities an important question in the setting of public utility rates is what constitutes a fair rate of return or cost of equity capital for a regulated utility recent debates over this issue have centred on the capm s ability to produce realistic equity cost figures for use in the rate setting process several researchers recommend modified or expanded versions of the market model as a means of improving its predictive capabilities one such approach is the lower partial moment model the purpose of the present paper is to assess the robustness of the lower partial moment model relative to the conventional capm as a basis for estimating the cost of a utility company s equity capital the hypothesis that empirical estimates of the lpm beta tend to overestimate the true systematic risk of utility companies was corroborated by our test results

market implication of predisc10sure information size and exchange effects differential market reactions to earnings announcements can inter alia be ascribed to the extent to which such announcements entail surprise i e unexpected information the greater the predisclosure information the less the surprise element in earnings announcements since there is no direct measure of predisclosure information the literature has utilized two different proxies i firm size the size effect atiase 1980 1985 and ii exchange listing the exchange effect grant 1980 atiase 1980 argues that private predisclosure information production and dissemination are an increasing function of firm size capitalization if so the amount of unexpected information conveyed to the market by actual earnings reports should be inversely related to firm size other things equal empirical evidence in atiase 1985 supports this hypothesis grant 1980 found that for otc firms the average price revaluation associated with annual earnings announcements is significantly higher in the report week relative to both nonannouncement

agricultural trade liberalization and economic development the role of downstream market power a model is developed to characterize the vertically linked and concentrated nature of developed country food markets this model is then parameterized and used to simulate the effects of varying food market structures on the benefits to developing country exporters of agricultural commodities from trade liberalization by developed countries results demonstrate that even relatively modest departures from perfect competition can cause much of the benefits from trade liberalization to flow to marketing firms instead of producers in the developing country the distributional effects under downstream market power differ significantly from the perfectly competitive case and may result somewhat paradoxically in developing countries receiving a lower share of the total value added within the food chain as trade reform occurs

errors in recorded security prices and the turn of the year effect errors in recorded security prices are a source of misspecification in the market model if recorded price errors are sufficiently nonrandom they result in biased returns and in biased and inconsistent estimates of market model regression coefficients this paper argues that tax induced flow supply pressures cause end of the year recorded price errors to be nonrandom enough to create the appearance of anomalous turn of the year stock return behavior empirical tests of returns and market model regression coefficients during the turn of the year period cannot reject this errors in variables explanation of the turn ofthe year effect the turn of the year toy effect or january effect refers to the anomal ous behavior of stock returns during the last five trading days in december and the first five trading days in january this anomaly is of particular interest to financial researchers because it appears to be a small firm effect and the source of the majority of size related anomalies see keim 1985 reinganum 1981 and roll 1983a 1983b the interest in the toy effect is justified because of its implications concerning the validity of the capital asset pricing model capm and market efficiency in this paper we show that there is a price related effect operating during the toy period first we show that the magnitude of the toy return is inversely related to price when we control for price most of the size related toy effect found by reinganum 1983 and roll 1983a disappears second the data indicate that all firms have unusually high returns during the toy period compared with their returns during the rest of the year third we find seasonal shifts in the market model betas associated with the toy period furthermore we test the hypothesis that the toy effect is an errors in variables problem due to the use of the one eighth pricing convention in recording security prices and the accommodation of tax induced flow pressures by liquidity traders such as market

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

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

good jobs versus bad jobs this article develops a model of noncompetitive labor markets in which high wage good and low wage bad jobs coexist minimum wages and unemployment benefits shift the composition of employment toward high wage jobs because the composition of jobs in the laissez faire equilibrium is inefficiently biased toward low wage jobs these labor market regulations increase average labor productivity and may improve welfare

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 capm and equity return regularities differential returns on dividend and capital gains income systematic abnormal returns surrounding ex dividend dates excess returns on small versus large capitalization stocks excess returns on low versus high price earnings ratio stocks these are among the recent findings that cast doubt on the traditional capital asset pricing model and tease investors with the promise of systematic excess returns some of these effects are undoubtedly related tests indicate for example that the higher a portfolio s price to book ratio the higher the corresponding values of market capitalization pie and stock price furthermore p e dividend yield price and pie effects all experience significant january seasonals what has not been conclusively determined is whether the effects are additive so far it appears that the dividend yield and size effects are not mnutually exclusive investors may want to use a strategy employing several of these characteristics rather than one efforts to explain the size effect have focused on january because the effect is concentrated in that month the most common hypothesis attributes this to year end tax loss selling but the evidence is less than conclusive evidence strongly suggests however that among small firms those with the largest abnormal returns tend to be the firms that have recently become small that either don t pay dividends or have higher dividend yields and that have lower prices and low pie ratios

nonstationary expected returns abstract recent evidence reveals significant negative serial correlation in aggregate market wide stock returns we extend this result to relative market adjusted returns demonstrating negative serial correlation in five year returns we then test two competing explanations 1 market mispricing and 2 changing expected returns in an efficient market the tests are conducted using the capital asset pricing model to estimate relative returns the evidence suggests that negative serial correlation in relative returns is due almost entirely to variation in relative risks and therefore expected relative returns through time we document substantial relative risk shifts particularly for extreme performing stocks

small firm growth access to capital markets and financial structure review of issues and an empirical investigation this article investigates the financial structure of small firms with an emphasis on growth and access to capital markets neo classical economic life cycle pecking order and agency theory perspectives are reviewed in order to formulate testable propositions concerning levels of long term short term and total debt and liquidity up to date financial data were collected from the u k private database for a large sample comprising of both listed and unlisted small firms regression results indicate significant relationships between financial structure and profitability asset structure size age and stock market flotation but not growth except when rapid and combined with lack of stock market flotation analysis of stock market flotation as an interactive dummy reveals major differences between listed and unlisted small firms the results indicate that the variety of financial structures observed in practice may reflect rational trade offs of various costs on the part of small firm owner managers but that the over reliance on internally available funds and the importance of collateral in the case of unlisted small firms are likely to be major constraints on economic growth

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

a direct test of roll s conjecture on the firm size effect empirical research indicates that small firms earn higher average rates of return than large firms even after accounting for beta risk roll conjectured that the small firm effect might be attributed to improper estimation of security betas the evidence shows that while the direction of the bias in beta estimation is consistent with roll s conjecture the magnitude of the bias appears to be too small to explain the firm size effect

stock return seasonalities and earnings information previous literature documents significant seasonalities in stock market returns one explanation is seasonality in earnings information if true a return index comprised solely of firms reporting earnings should exhibit stronger intertemporal seasonalities than a return index comprised of firms not reporting earnings employing all new york and american stock exchange firms over six years this study examines the seasonality of stock returns generally seasonal patterns for reporting returns are found to be similar to or slightly weaker than for nonreporting returns thus it is doubtful that earnings news seasonality induces stock return seasonality

stock market anomalies abstract this paper reports evidence documenting the presence of a number of irregularities in stock price behaviour of firms on the london stock exchange the size effect is not only not the sole anomaly but is not even the most dominant one specifically investment strategies based on dividend yield pe ratios and share prices appear as profitable if not more as a strategy concentrating on firm size although there is a large degree of interdependency between all four effects it is still apparent that the dividend yield and pe ratios subsume the size and share price effects

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

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

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

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

equilibrium wage dispersion and interindustry wage differentials this paper develops a search theoretic explanation of interindustry wage differentials given coordination problems in the labor market the probability of filling a vacancy is an increasing function of the wage offered in equilibrium firms that find vacancies more costly will offer higher wages the model thus explains the persistence of interindustry wage differentials and their correlation with industry average capital labor ratio and profitability additionally the model predicts that high wage firms will receive more applications per job opening and that wages in the labor market will behave as strategic complements

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

price regulation in property liability insurance a contingent claims approach a discrete time option pricing model is used to derive the fair rate of return for the property liability insurance firm the rationale for the use of this model is that the financial claims of shareholders policyholders and tax authorities can be modeled as european options written on the income generated by the insurer s asset portfolio this portfolio consists mostly of traded financial assets and is therefore relatively easy to value by setting the value of the shareholders option equal to the initial surplus an implicit solution for the fair insurance price may be derived unlike previous insurance regulatory models this approach addresses the ruin probability of the insurer as well as nonlinear tax effects

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

market values earnings yields and stock returns evidence from singapore abstract results of u s studies about the relation between stock returns and the effects of firm size and earnings to price ratio e p are not consistent basu 1983 argues that e p dominates size while others conclude that size dominates e p this paper attempts to provide evidence on these two effects with a sample of data 1975 1985 from the stock exchange of singapore we find that stock returns are significantly related to both size and e p but the size effect appears to be of secondary importance when compared with e p effect

measuring abnormal performance do stocks overreact abstract a highly controversial issue in financial economies is whether stocks overreact in this paper we find an economically important overreaction effect even after adjusting for size and beta in portfolios formed on the basis of prior five year returns extreme prior losers outperform extreme prior winners by 5 10 per year during the subsequent five years although we find a pronounced january seasonal our evidence suggests that the overreaction effect is distinct from tax loss selling effects interestingly the overreaction effect is substantially stronger for smaller firms than for larger firms returns consistent with the overeaction hypothesis are also observed for short windows around quarterly earnings announcements

the aftermarket performance of small firm initial public offerings abstract the dream of many entrepreneurs is to some day take his or her growing small firm public and to thereby become the ceo of a publicly traded corporation currently entrepreneurs are continuing to utilize initial public offerings ipos as a viable source of venture financing ipos also represent a viable mechanism for harvesting venture capital and entrepreneurial investments the touted entrepreneurial benefits of taking a company public include the abilities to borrow additional funds return to the public equity market negotiate mergers without depleting cash the potential for enhanced personal wealth and so forth investors in small firm public equity issues are often motivated by the potential for discovering another apple computer or perhaps an ibm at the ground floor this study empirically examines the aftermarket returns of small publicly held firms that have issued initial public offerings aftermarket returns refers to stock returns immediately after a stock begins trading the study specifically examines two questions first is there a positive risk return relationship for small firm aftermarket returns where higher firm risk will generate higher aftermarket return second will aftermarket returns show on industry effect where certain industries will automatically generate higher returns answers to these questions will affect the strategic financial alternatives available to entrepreneurs both before and after going public and will also affect the decisions of investors interested in financing small public corporations the research findings indicate that entrepreneurs planning to take younger firms public will probably not have available to them numerous subsequent financial alternatives utilizing corporate stock if the true aftermarket performance of their stock is taken into consideration likewise investors in small firm public issues may also be disappointed in the aftermarket performance of younger firms a positive risk return relationship where age was a proxy measure of risk did not exist this was true even though the initially quoted returns of these same younger firms may have been substantial on the other hand the aftermarket performance of older firms is typically favorable finally the study suggests that neither entrepreneurs nor investors should bet solely on a particular industry categorization to carry their aftermarket stock performance while certain industries indicated significant positive initial returns aftermarket returns based on industry classification were generally not statistically significant investors should therefore always exercise firmspecific due diligence and research before investing in small firm public equity issues since the variance of their aftermarket market returns tends to be large

seasonality in canadian stock prices a test of the tax loss selling hypothesis a popular hypothesis to explain the anomalous january returns of common stocks is based on the argument that there is considerable tax loss selling by investors toward the end of the year the purpose of this study is to test the tax loss selling hypothesis with data on canadian stocks although the introduction of capital gains tax in canada seems to have affected the behavior of stock returns the findings do not support the proposition that taxinduced trading is the sole cause ofthe seasonality in stock returns in canada i introduction over the past several years a number of studies have shown that the returns on common stocks in general and the stocks of small companies in particular tend to be abnormally high during the month of january keim 10 demonstrated quite clearly that a very high percentage of the abnormal positive returns gener ated on stocks with low market capitalizations occurs during january with the returns during the first five trading days of the year accounting for most of the anomalous behavior his results were recently confirmed by roll 14 who re ported that around 37 percent of the annual differences in the returns on the equally weighted and value weighted indices of nyse and amex stocks is ac counted for by what happens in the five trading days from the last trading day in december through the fourth trading day in january a popular hypothesis to explain the so called january effect in stock re turns is based on the argument that there is considerable end of the year tax lossselling by investors originally proposed by wachtel 19 it asserts that inves tors try to realize losses towards the end of the year to reduce their taxes thereby putting downward pressure on stock prices according to the hypothesis once

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

optimal stock trading with personal taxes implications for prices and the abnormal january returns abstract the tax law confers upon the investor a timing option to realize capital losses and defer capital gains with the tax rate on long term gains and losses being about half the short term rate the law provides a second timing option to realize losses short term and gains long term if at all our theory and simulation over the 1962 1977 period establish that taxable investors should realize long term gains in high variance stocks and repurchase stock in order to realize potential future losses short term tax trading does not explain the small firm anomaly but predicts a seasonal pattern in trading volume which maps into a seasonal pattern in stock prices the january anomaly only if investors are irrational or ignorant of the price seasonality

capital deepening and wage differentials germany versus us in flexible labour markets capital increases the productivity of skilled workers more than that of unskilled workers and in the us faster investment is associated with wider wage inequality but labour market institutions that keep unskilled workers wages high also imply that firms may find it profitable to invest so as to boost those workers productivity our empirical analysis based on industry level data confirms that a higher capital intensity in germany is associated with smaller wage differentials and with a larger share of unskilled workers in the labour costs changes in capital labour ratios during the 1980s reduced wage differentials by 5 8 in german industries while in the us capital deepening in such industries as machinery and retail was accompanied by an increase of wage differentials larger than 7 winfried koeniger and marco leonardi

diverging trends in aggregate and firm volatility this note documents the diverging trends in volatility of the growth rate of sales at the aggregate and firm levels we establish that the upward trend in firm volatility is not simply driven by a compositional bias in the sample studied we argue that this new fact brings into question the proposed explanations for the decline in aggregate volatility and that given the symmetry of the diverging trends at the micro and macro levels a common explanation is likely we conclude by describing one such theory

evidence on tax motivated securities trading behavior tax loss selling by investors in common stocks near the end of calendar years has been proposed as an explanation for the turn of the year effect in stock returns past analyses of this hypothesis have relied on inferential data we provide here some direct data from a compilation of over 80 000 actual common stock investment round trips by a sample of 3000 individual investors we find strong evidence of a concentration of loss taking trades late in the year and milder evidence of a concentration just prior to the dates when investments become eligible for long term tax treatment the question as to whether and in what manner the impostion of a tax on realized capital gains affects the securities trading behavior of investors who are subject to the tax has been a longstanding topic of research in the financial ecomonics literature the original attention devoted to the matter was motivated primarily by a concern about resource allocation and federal tax revenue consequences and was directed toward the phenomenon of what has been termed the lock in effect of a gains tax that issue has remained an important public policy one and continues today as part of the ongoing debate about appropriate strategies for reducing the federal budget deficit particular additional interest in the topic has emerged in recent years however because securities transactions undertaken systematically for tax reasons have also been proposed as part of the explanation for certain observed anomalies in historical common stock returns most prominently the well documented turn of the year effect our purpose here is to provide some new evidence that decisions by investors as to the timing of the realization of capital gains and losses from their common stock investments are significantly affected by tax considerations this evidence indicates that a difference in the tax rates applicable to realizations classified as short and long term influences the timing of individual investors trades and further that there is a clear tendency for trades by individuals which give rise to losses to be concentrated near the end of calendar which for them are also tax years while we cannot conclude that

seasonality stock returns and the macroeconomy this paper examines the relationship between seasonality stock returns and the macroeconomy using a multifactor model of stocks returns observed seasonal patterns in excess returns are found to be a result of seasonality in excess expected returns by utilising a multifactor model of stock returns these higher returns are found to be a compensation for risk associated with a number of macroeconomic factors at certain times of the year

risk and return abstract this paper examines the seasonality in the basic relationship between expected return and risk during 1935 82 the results reveal that the positive relationship between return and risk is unique to january the risk premiums during the remaining eleven months are not significantly different from zero

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

turn of month evaluations of liquid profits and stock returns a common explanation for the monthly and january effects this paper presents and tests a hypothesis that the standardization of payments in the united states at the turn of each calendar month generally induces a surge in stock returns at the turn of each calendar month the hypothesis also asserts that returns generally will be greater following the month of december and will vary inversely with the stringency of monetary policy empirical results using stock index returns for 19691986 support the hypothesis this analysis provides an explanation for the previously documented monthly effect in stock returns and a partial explanation for the january effect in a recent paper ariel 1987 documents an important empirical regularity in stock returns and terms it the monthly effect using value weighted and equally weighted daily stock index returns for the period 1963 1981 ariel shows that virtually all of the cumulative return on these indexes is realized on ten consecutive trading days of the calendar month beginning with the last trading day of the month and extending through the first nine trading days of the following month ariel considers various explanations for this phenomenon but none sufficed to explain the observed empirical regularity p 174 more recently lakonishok and smidt 1988 examine returns on the dow jones industrial average index for the period 1897 1986 and find that significant mean daily returns are realized consistently on only four consecutive trading days of the calendar month beginning with the last trading day of the month these trading days will henceforth be referred to as the turn of month trading days ariel s and lakonishok and smidt s tests indicate that the monthly effect is not merely another manifestation of the previously documented january effect rozeff and kinney 1976 first documented that average stock index returns in january are higher than in any other month keim 1983 and others find that the surge in january returns is largely confined to stocks of small firms and to the first few trading days in january branch 1977 and others have suggested that the surge in january returns is due to year end tax loss selling and subsequent repurchases in january studies by roll 1983 reinganum 1983 ritter 1988 and others provide evidence consistent with the tax loss selling

the relation between common stock returns trading activity and market value this study examines the relation between common stock returns trading activity and market value our results indicate that although firm size and trading activity are highly correlated differences in trading activity are not the underlying reason for the firm size anomaly the finding of systematic differences in risk adjusted returns across stocks of firms of different size recent empirical research has revealed systematic differences in risk adjusted returns for common stocks of firms of different sizes as measured by the market value of outstanding common stock see banz 1 and reinganum 5 roll 7 in a recent paper has suggested that the firm size anomaly may result from errors in risk measurement in particular roll suggested that because small firms trade less frequently than large firms risk measures obtained from daily or weekly returns data may seriously underestimate the risk associated with holding a portfolio of small firms in response to roll s conjecture reinganum 6 examined the risk adjusted returns of portfolios formed on the basis of firm size using both the scholes williams 8 and the dimson 2 aggregated coefficient method of estimating portfolio betas and found that regardless of the beta estimation technique employed differences in estimated betas were insufficient to account for differences observed in the returns of size ranked portfolios if reinganum s 6 finding is correct that the firm size effect is not attributable to a misassessment of risk and if smaller firms trade less frequently than do larger firms then firm size may merely proxy for trading activity 1 thus the observed firm size effect may be explained in terms of a liquidity premium associated with inactively traded shares the purpose of this paper is to determine whether or not the firm size anomaly is explicable in terms of differences in the trading activity of common stocks a liquidity premium would provide a logically appealing explanation for the firm size effect tinic 11 demsetz 3 and others have argued that transactions costs vary inversely with trading activity as measured by average number of

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

the effects of itq management on fishermen s welfare when the processing sector is imperfectly competitive in this paper we use a general model of imperfect competition to predict welfare changes within an open access fishery after it transitions to individual transferable quota itq management although related research has explored the effects of market power in the harvesting sector on itq performance none has considered the implications of an imperfectly competitive processing sector addressing this question we find that although fishermen should expect to gain from itqs under perfect competition they may suffer welfare losses if the processing sector is imperfectly competitive

an empirical study of selected factors influencing the decision to list on foreign stock exchanges the growing internationalization of capital markets suggests that an increasing number of firms perceive the benefits of listing their stocks on foreign exchanges as outweighing the related costs many other firms however still limit listing their securities to their domestic exchanges this study investigates the motives for listing abroad the empirical analyses based on data on 481 multinationals indicate significant association between the likelihood of listing abroad and 1 the relative size of a firm in its domestic capital market 2 the ratio of foreign to total sales

are seasonal anomalies real a ninety year perspective in recent years there has been a proliferation of empirical studies documenting unexpected or anomalous regularities in security rates of return in addition to the widely studied relation between firm size and rate of return 1 these include seasonal regularities related to the time of the day harris 1986 the day of the week see ball and bowers 1986 cross 1973 french 1980 gibbons and hess 1981 jaffe and westerfield 1985 keim and stambaugh 1984 and lakonishok and levi 1982 the time of the month ariel 1987 and the turn of the year see haugen and lakonishok 1988 jones pearce and wilson 1987 lakonishok

tax loss selling and the january effect evidence from municipal bond closed end funds this paper provides direct evidence supporting the tax loss selling hypothesis as an explanation of the january effect examining turn of the year return and volume patterns for municipal bond closed end funds which are held mostly by tax sensitive individual investors we document a january effect for these funds but not for their underlying assets we provide evidence that this effect can be largely explained by tax loss selling activities at the previous year end moreover we find that funds associated with brokerage firms display more tax loss selling behavior suggesting that tax counseling plays a role among the numerous stock return anomalies probably none has generated more interest than that of the turn of the year or january effect the phenomenon in which small capitalization stocks realize unusually high returns in early january 1 the literature offers a number of hypotheses to explain this phenomenon including the tax loss selling hypothesis the window dressing hypothesis the insider trading information release hypothesis and the seasonality of the risk return relation hypothesis given existing evidence in some support for the first two hypotheses the debate continues with respect to which of these the tax loss selling of individual investors or the window dressing of

event study methodologies and the size effect abstract this study of 862 press recommendations demonstrates that the size effect can distort longer term performance measures and hence event studies relative to similar sized companies post publication performance is neutral however market adjustments the capm and market model with equally or capitalization weighted indexes all produce biased results event studies are most exposed to such bias when the measurement interval is long event securities differ systematically in size or weighting from the index constituents the size effect is large and or volatile and when capm type methodologies are used these distortions are avoided by explicitly controlling for size

the effect of holdings data frequency on conclusions about mutual fund behavior abstract a number of articles in financial economics have used quarterly or semi annual mutual fund holdings data to test hypotheses about investment manager behavior this article reexamines four well known hypotheses in finance to determine whether the results of prior tests of these hypotheses remain valid when higher frequency monthly holdings data are employed the areas examined are momentum trading tax motivated trading window dressing and tournament behavior we find that the use of monthly holdings data rather than quarterly holdings data or in the case of tournament behavior holdings data rather than monthly return data change and in some cases reverse previous results this occurs because monthly holdings data capture a large number of trades missed by quarterly data 18 5 of the trades and permit a more precise estimation of the timing of trades

tests of the capm with time varying covariances a multivariate garch approach this paper examines an asset pricing model in which the sharpe lintner capm and the zero beta capm are special cases the model allows the ratio of expected market risk premium to market variance the conditional expected excess returns and the risks to change over time the results are found to be sensitive to the choice of the portfolio formation techniques significant time variability is shown in the conditional expected excess asset returns and risks and also in the reward to risk ratio

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

ability biased technological transition wage inequality and economic growth thispaper develops a growthmodel characterizedbyability biasedtechnological transition in which the evolution of technology education attainment and wage inequality is consistent with the observed pattern in the united states and other advanced countries over the past several decades it argues that an increase in the rate of technological progress raises the return to ability and simultaneously generates an increase in wage inequality between and within groups of skilled and unskilled workers an increase in average wages of skilled workers a temporary decline in average wages of unskilled workers an increase in education and a productivity transitory slowdown

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

the seasonal stability of the factor structure of stock returns this paper investigates the month by month stability of a daily returns and correlation coefficients of stock returns b correlation and covariance matrices c number of return generating factors and d the apt pricing relationship the results show that there is a january effect and a small firm effect in stock returns correlation matrices are more stable than covariance matrices but both types of matrices are not stable across months and across the sample groups the number of return generating factors is rather stable most of the time and for most of the sample groups but there is some significant instability that is related to the average correlation coefficients among stocks the apt pricing relationship does not seem to be supported by the two stage process using the maximum likelihood factor analysis the seasonality of common stock returns has received considerable attention in financial economics research studies by officer 23 rozeff and kinney 29 gultekin and gultekin 11 and others have investigated the stock returns of the u s and other countries on a monthly basis they generally have found that on average january returns are significantly higher than the returns for other months banz 1 and reinganum 25 26 have found abnormally high returns in small market value firms and keim 17 has related this to the first few trading days of january schwert 30 points out the current difficulty of explaining these empirical regularities and the need for further investigations several studies have examined seasonality in risk premiums rozeff and kinney 29 found that seasonality appeared in the risk premiums obtained from a twoparameter capm and that january displayed a relatively large risk premium compared with the other months keim 16 also found seasonality in the risk premiums more recently tinic and west 32 examined the risk premiums of the two parameter capm and observed the previously reported seasonality and high january premium they also found that january is the only month in which there is a consistently positive statistically significant relationship between expected return and risk very recently using the two stage procedure with the

financial analysts forecasts of earnings a better surrogate for market expectations abstract the specification of the market expectation of accounting numbers is a common feature of many empirical studies in accounting and finance givoly and lakonishok 1979 found that financial analysts forecasts have information content this study evaluates the quality of analysts forecasts as surrogates for the market expectation of earnings and compares it with that of prediction models commonly used in research results indicate that prediction errors of analysts are more closely associated with security price movements suggesting that analysts forecasts provide a better surrogate for market expectations than forecasts generated by time series models the study also identifies factors that might contribute to the performance of the financial analysts forecasts the broadness of the information set employed by analysts and to a lesser extent their reliance on information released after the end of the fiscal year appear to be important contributors to their performance

overreaction underreaction and the low p e effect although earnings surprises have been studied extensively they have not been examined in the context of contrarian strategies positive and negative earnings surprises affect best high p e and worst low p e stocks in an asymmetric manner that favors worst stocks long term reversion to the mean in which worst stocks display above market returns while best stocks show below market results regardless of the sign of the surprise continues for at least 19 quarters following the news these results are consistent with mispricing overreaction to events prior to the surprise and a corrective price movement after the surprise is consistent with extant research on underreaction the mispricing correction hypothesis explains the superior returns of contrarian strategies noted here and elsewhere in the literature

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

worker cooperation and the ratchet effect workers paid by the piece should be happy to introduce new techniques that increase output but firms always seem to reduce the piece rate when workers start earning too much money workers respond by restricting output and keeping good new ideas to themselves we show that this outcome is inevitable in a competitive environment however there are noncompetitive situations where firms can use piece rates to get cooperation from their workers these predictions are consistent with case history evidence from the cotton spinning industry in england in the nineteenth century and the lincoln electric company in the united states even today

institutions and individuals at the turn of the year this article evaluates the tax loss selling hypothesis against the window dressing hypothesis as explanations for turn of the year anomalies we examine differences between securities dominated by individual investors versus those dominated by institutional investors and find that the effect is more pervasive in the former controlling for capitalization we find that in early january late december stocks with greater individual investor interest outperform underperform stocks with greater institutional investor interest these results hold for both stocks that previously appreciated in value and stocks that previously depreciated in value the results are most consistent with the tax loss selling hypothesis as an explanation for the turn of the year effect

technological acceleration skill transferability and the rise in residual inequality this paper provides a quantitative theory for the recent rise in residual wage inequality consistent with the empirical observation that a sizable part of this increase has a transitory nature a feature that eludes standard models based on ex ante heterogeneity in ability an acceleration in the rate of quality improvement of equipment like the one observed from the early 1970s increases the productivity quality differentials across machines jobs in a frictional labor market this force translates into higher wage dispersion even among ex ante equal workers with vintage human capital the acceleration reduces workers capacity to transfer skills from old to new machines generating a rise in the cross sectional variance of skills and therefore of wages through calibration the paper shows that this mechanism can account for 30 percent of the surge in residual inequality in the u s economy or for most of its transitory component two key implications of the theory faster within job wage growth and larger wage losses upon displacement find empirical support in the data

personal income taxes and the january effect small firm stock returns before the war revenue act of 1917 a note this paper tests the tax explanation of the january effect by examining small firm stock returns before the war revenue act of 1917 no evidence of a turn of the year effect is found this paper also extends previous authors work on the subject to 191829 a january effect is found during that period the large abnormal returns earned by small firm stocks during the first few days of january is attracting considerable attention from financial economists specifically keim 10 shows that over the entire 1963 79 period the average difference between risk adjusted returns of small and large firms is about 0 7 per day during january even more striking is the finding of keim 9 that over the entire 1931 78 period the relation between daily abnormal returns and size is always negative and more pronounced in january than in any other month similarly ibbotson and sinquefield 8 note that the average return on the quintile of nyse stocks with the lowest market values exceeds the return on the standard and poor s corporate index for 50 of the 56 januarys from 1926 81 there is no accepted theory linking the excess returns of small firms in january with the change of the tax year nevertheless the plausibility of a relation between taxes and stock return seasonality has led roll 17 brown et al 6 berges mcconnell and schlarbaum 2 and reinganum 16 among others to investigate personal income taxes as an explanation for the january effect this paper uses a different methodology and reaches stronger conclusions than any of the above papers specifically i examine the returns of small firms for the period from 1900 to 1929 prior to the revenue act of 1917 marginal income tax rates for investors were very low or zero the major finding of this paper is that there is no evidence that small firms earned abnormal returns in january prior to the 1917 tax act i also show that a january effect does appear during the years 1918 29 therefore i cannot reject a tax explanation for the january effect

seasonal and size anomalies in the japanese stock market little attention has been paid by the academic community in the united states to the japanese stock market and its structure japan has the second largest economy in the western world and the tokyo stock exchange tse is second only to the new york stock exchange nyse in terms of aggregate market values and sales volume analysis of the japanese stock market is useful given its relative importance but in addition examination of the japanese market may offer insights into controversies surrounding u s markets this study focuses on two such current controversies the january and size anomalies
