when do high stock returns trigger equity issues abstract one of the most prominent stylized facts in corporate finance is that equity issues tend to follow periods of high stock returns we document that firms exhibit such timing behavior only in response to high returns that coincide with strong institutional investor demand when not accompanied by institutional purchases stock price increases have little impact on the likelihood of equity issuance the results highlight the importance of market reception for the timing of equity issues

can foreign aid reduce income inequality and poverty this paper s goal is to examine the effect of foreign aid on income inequality and poverty reduction for the period 1971 2002 since simple cross country regressions cannot be taken as true time series findings we focus on dynamic panel data techniques which allow accounting for potential simultaneity and heterogeneity problems we find some weak evidence that foreign aid is conducive to the improvement of the distribution of income when the quality of institutions is taken into account however this result is not robust this finding is consistent with recent empirical research on aid ineffectiveness in achieving economic growth or promoting democratic institutions

reducing bureaucratic corruption interdisciplinary perspectives on what works abstract this article offers the first comprehensive review of the interdisciplinary state of knowledge regarding anti corruption policies with a particular focus on reducing corruption among civil servants drawing on the work of economists political scientists sociologists and anthropologists we examine seven policy categories 1 rewards and penalties 2 monitoring 3 restructuring bureaucracies 4 screening and recruiting 5 anti corruption agencies 6 educational campaigns and 7 international agreements notably rigorous empirical evaluation is lacking for the majority of commonly prescribed anti corruption policies nevertheless we find growing evidence of the effectiveness of policies based on monitoring including anti corruption audits and e governance in addition adequate civil service wages seem to be a necessary but insufficient condition for control of corruption an emerging skepticism regarding the effectiveness of anti corruption agencies also is apparent in the literature we conclude with broader lessons drawn from our review such as the recognition that when corruption is a systemic problem it cannot be treated in the long term with individual level solutions

analyst forecasts and herding behavior the use of analyst forecasts as proxies for investors earnings expectations is commonplace in empirical research an implicit assumption behind their use is that they reflect analysts private information in an unbiased manner as demonstrated here this assumption is not necessarily valid there is shown to be a tendency for analysts to release forecasts closer to prior earnings expectations than is appropriate given their information further analysts exhibit herding behavior whereby they release forecasts similar to those previously announced by other analysts even when this is not justified by their information these results are shown to have interesting empirical implications article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

security analysis and trading patterns when some investors receive information before others in existing models of information acquisition all informed investors receive their information at the same time this article analyzes trading behavior and equilibrium information acquisition when some investors receive common private information before others the model implies that under some conditions investors will focus only on a subset of securities herding while neglecting other securities with identical exogenous characteristics in addition the model is consistent with empirical correlations that are suggestive of oft cited trading strategies such as profit taking short term position reversal and following the leader mimicking earlier trades in existing models of information acquisition all informed investors receive their information at the same time while these models provide many important insights in reality some investors either fortuitously or owing to superior skill acquire pertinent information before others by being first an investor can exploit this information to great advantage information that is uncovered only slightly later is less valuable even if it has not yet been publicly revealed we show in this article that the sequential nature of information arrival has a significant effect on both the trading decisions and the types of information collected by investors the model we develop describes the investment choices of a set of competitive risk averse investors who investigate the long term prospects of firms lucky or high ability investors uncover the

whose business is it anyway this article examines how gender may account for productivity gaps across enterprises first using data from six countries in sub saharan africa the article demonstrates that the extent and significance of any productivity gap by gender depends critically on the criteria used to classify an enterprise using a definition of female participation in ownership there are few differences in average performance measures however a 12 productivity gap emerges when a tighter definition based on decision making control is used second the article examines which entrepreneurial characteristics education management skills experience and the motivation for being an entrepreneur are most associated with higher productivity the findings reveal that there are some gender gaps in the prevalence of these characteristics but that these do not account for the overall gender productivity gap rather while women benefit as much as men from education and management skills there are non linear impacts by gender in the benefits of having a family background in entrepreneurship sons rather than daughters benefit from having a father that was an entrepreneur or from joining a family enterprise

pay and productivity differences between male and female veterinarians the author uses data from annual wage surveys conducted in 1994 and 1995 by medical economics research group to study differences in pay and productivity between male and female veterinarians in the wage salary sector the gender gap in average earnings was 15 when controls for various observable characteristics are added to the analysis the earnings gap narrows to 9 based on the most conservative estimates using unique revenue production measures in an analysis holding other factors constant the author finds that women s productivity was not statistically different from men s together the findings of gender differences in earnings but not in productivity are consistent with the presence of wage discrimination but the author explores other possible explanations as well

the effect of foreign aid on corruption a quantile regression approach abstract this paper investigates the effect of foreign aid on corruption using a quantile regression method we show that foreign aid generally reduces corruption and its reduction effect is greater in less corrupt countries moreover this effect is different by different donor countries

institutional herding in international markets abstract this paper studies herding behavior of institutional investors in international markets first we document the existence of wide spread herding in 41 countries referred to as target countries hereafter in the sample we then examine the relation between contemporaneous institutional demand and future returns and find that institutional herding stabilizes prices next we examine the relation between institutional investors herding behavior and the level of information asymmetry in the target countries we measure the degree of information asymmetry in each target country along five dimensions 1 stock market development 2 ease of access to information 3 corporate transparency 4 investor rights and 5 macroeconomic factors that relate to the information environment we find evidence that institutional investors herd more in markets characterized by low levels of information asymmetry high level of information transparency this result suggests that institutional investors herding behavior is likely driven by correlated signals from fundamental information lastly we show that price adjustment is faster in informationally transparent markets

portfolios in disguise window dressing in bond fund holdings abstract this paper builds on the limited body of research on window dressing by bond mutual funds our monthly bias free sample allows us to undertake a more comprehensive study than is possible with the quarterly data traditionally employed in otherwise similar studies we test window dressing in a straightforward manner using monthly undisclosed portfolios which makes it possible to compare changes in public debt allocations around quarterly disclosures our results support the hypothesis that window dressing patterns vary with market conditions we also conduct thorough tests that indicate the significant influence of fund size on window dressing individual analyses provide evidence that this cosmetic practice is not a widespread behaviour in the spanish bond fund industry

momentum investment strategies portfolio performance and herding a study of mutual fund behavior this study analyzes the extent to which mutual funds purchase stocks based on their past returns as well as their tendency to exhibit herding behavior i e buying and selling the same stocks at the same time the authors find that 77 percent of the mutual funds were momentum investors buying stocks that were past winners however most did not systematically sell past losers on average funds that invested on momentum realized significantly better performance than other funds the authors also find relatively weak evidence that funds tended to buy and sell the same stocks at the same time copyright 1995 by american economic association

gender differences in labor market decisions evidence from rural mexico this study examines gender employment differences in mexicos rural sector using the 1994 survey of rural entrepreneurs and financial services it employed an approach that separate the effects of initial endowments from the gender differences that can be attributed to preferences available opportunities labor market discrimination and other market conditions all of which referred to as labor market structural issues findings show that higher levels of education are associated with a higher employment propensity although the variable for some secondary schooling is not significant for men as expected married men are more likely to be employed than single men while for females the opposite results ensues which indicate that women in rural areas tend to specialize in non market activities particularly after marriage also gender differences in labor market experience proxied by age seems to influence the self employment choice these results have implications for public policy aimed at reducing gender inequality in labor market outcomes in rural mexico the main lesson is that policies that focus solely on individual endowments could have a limited impact on reducing gender inequality if they are not accompanied by policies addressing structural supply and demand factors that are unique to the study population and that influence the choice of women to enter and remain in the workforce

early career work experience and gender wage differentials we estimate a wage model that includes an array of variables measuring the fraction of time worked during each year of the career this array fully characterizes past employment experience regardless of how sporadic it has been our model yields substantially higher estimated returns to experience and lower returns to tenure than do models that measure experience cumulatively and use the standard quadratic functional form we find that the data reject the standard model but fail to reject our model furthermore we find that 12 of the male female wage gap is due to differences in the timing of work experience

insider trades and demand by institutional and individual investors there is a strong inverse relation between insider trading and institutional demand the same quarter and over the previous year our analysis suggests a combination of factors contribute to this relation first institutional investors are more likely to provide the liquidity necessary for insiders to trade second insiders are more likely to buy low valuation and low lag return stocks while institutions are attracted to the opposite security characteristics last the results are consistent with the hypothesis that insiders are more likely to view their securities as overvalued undervalued following a period when institutions were net buyers sellers the author 2010 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

reducing start up costs for new firms the double dividend on the labor market starting a firm with expansive potential is an option for educated and high skilled workers if there are labor market frictions this additional option can be seen as reducing the chances of ending up in a low wage job and hence as increasing the incentives for education in a matching model we show that reducing the start up costs for new firms results in higher take up rates of education it also gives rise through a thick market externality to higher rates of job creation for high skilled labor as well as average match productivity we provide empirical evidence to support our argument

private information trading volume and stock return variances new evidence is provided on the determinants of stock return variances first when the tokyo stock exchange is open on saturday the weekend variance increases weekly variance is unaffected however despite an increase in weekly volume second the listing of u s stocks in tokyo substantially increases the number of trading hours but tokyo volume is negligible for these u s stocks and their 24 hour variance is unaffected the overall results are consistent with the predictions of private information based rational trading models but inconsistent with both the irrational trading noise and public information hypotheses

information disclosure and price manipulation during the pre closing session evidence from an order driven market on 20 february 2012 the taiwan stock exchange corporation launched an order matching simulation mechanism for five minutes during the start of the pre closing session in order to increase information disclosure during this period 13 25 13 30 pre closing information disclosure significantly reduces both trading costs and closing price volatility as well as price manipulation the decrease in price manipulation found in this work is due to pre closing information disclosure not the behaviour of investors shifting to an earlier time further if a stock price rises or falls by more than 3 5 in the simulation in the last minute during the closing session trading of the stock will be suspended for two minutes from 13 31 to reduce volatility however this trading mechanism suspended closing does not seem to have achieved the intended goals of the authorities as it has not been able to significantly reduce closing price volatility and price manipulation

are foreign owned firms more likely to pay bribes than domestic ones evidence from emerging markets summary an extensive literature exists on the adverse effects of corruption on inward fdi and the impact this may have on economic development but the reverse causality has not been fully explored legislation in the us and the eu prohibits firms from engaging in corrupt practices in foreign countries and this suggests that foreign owned firms might be less likely to pay bribes however such legislation may be ineffective because foreign firms have to adapt to local market conditions or risk being uncompetitive using firm level data for 41 emerging countries a probit model estimates the probability that a firm pays bribes to allow for possible endogeneity this probit analysis is repeated with an instrument to proxy for endogenous foreign ownership then a propensity score matching technique tests for differences in the propensity to pay bribes by domestic and foreign firms the paper finds no difference in the behavior of foreign owned and domestic firms with respect to corrupt practices results are robust to different levels of foreign ownership and support the view that foreign owned firms adapt to local practices and are neither more nor less likely to pay bribes than comparable domestic firms the paper finds that other variables including bureaucracy government contracts and perceived difficulties with civil society legal and political do have statistically significant effects on increasing bribery and that some others such as per capita gdp tend to reduce bribery the study concludes that there is no evidence that foreign ownership after investment has occurred tends to reduce bribery but it does support the view that foreign owned firms adopt local behavioral norms

what do we really know about wages the importance of nonreporting and census imputation in the most frequently used microdata sets over a quarter of all respondents now refuse to answer some questions about their incomes the census bureau has dealt with this problem which has been increasing in severity over time by imputing incomes of non respondents their imputation procedure called the hot deck essentially matches nonrespondents with demographically similar donors in this paper we evaluate the census imputation methodology and raise some questions first the census procedure is tied to commonality of events in the population rather than the more appropriate informational content of regressors clearly the census procedure severely understates income in certain occupations because it is based on the apparently invalid assumption that income does not affect reporting propensities it most likely understates average incomes as well

the mobile phone in the diffusion of knowledge for institutional quality in sub saharan africa this study assesses the mobile phone in the diffusion of knowledge for better governance in sub saharan africa from 2000 to 2012 for this purpose we employ generalised method of moments with forward orthogonal deviations the empirical evidence is based on three complementary knowledge diffusion variables innovation internet penetration and educational quality and 10 governance indicators that are bundled and unbundled the following are the main findings first there is an unconditional positive effect of mobile phone penetration on good governance second the net effects on political economic and institutional governances that are associated with the interaction of the mobile phone with knowledge diffusion variables are positive for the most part third countries with low levels of governance are catching up their counterparts with higher levels of governance the above findings are broadly consistent with theoretical underpinnings on the relevance of mobile phones in mitigating bad governance in africa the evidence of some insignificant net effects and decreasing marginal impacts may be an indication that the mobile phone could also be employed to decrease government quality overall this study has established net positive effects for the most part five rationales could elicit the positive net effects on good governance from the interaction between mobile phones and knowledge diffusion among others the knowledge variables enhance reach access adoption cost effectiveness and interaction in a nut shell the positive net effects are apparent because the knowledge diffusion variables complement mobile phones in reducing information asymmetry and monopoly that create conducive conditions for bad governance the contribution of the findings to existing theories and justifications of the underlying positive net effects are discussed

empirical determinants of corruption a sensitivity analysis many variables have been proposed by past studies as significant determinants of corruption this paper asks if their estimated impact on corruption is robust to alteration of the information set a global sensitivity analysis based on the leamer s extreme bounds analysis gives a clear answer five variables are robustly related to corruption corruption is lower in richer countries where democratic institutions have been preserved for a long continuous period and the population is mainly protestant corruption is instead higher where political instability is a major problem finally a country s colonial heritage appears to be a significant determinant of present corruption

the behavior of stock prices around institutional trades all trades executed by 37 large investment management firms from july 1986 to december 1988 are used to study the price impact and execution cost of the entire sequence package of trades that we interpret as an order we find that market impact and trading cost are related to firm capitalization relative package size and most importantly to the identity of the management firm behind the trade money managers with high demands for immediacy tend to be associated with larger market impact financial economists have long studied the equity trading process and its impact on stock prices much prior empirical research isolates individual trades and analyzes the behavior of the stock price around each trade see for example kraus and stoll 1972a holthausen leftwich and mayers 1987 1990 keim and madhavan 1991 petersen and umlauf 1991 hausman lo and mackinlay 1992 and chan and lakonishok 1993 evaluating the behavior of stock prices around trades provides a means of discriminating among various hypotheses as to the elasticity of the demand for stocks yields an estimate of the cost of executing trades and a measure of the liquidity of a market and permits tests of different models of the determination of quotes and transaction prices for many institutional investors however even a moderately sized position in a stock may represent a large fraction of the stock s trading volume accordingly an investment manager s order is often broken up into several trades it is often misleading therefore to consider an individual trade as the basic unit of analysis in the study of trading activity and its effects on prices this paper uses the record of trades executed by 37 large investment manage

identifying the interaction between stock market returns and trading flows of investor types looking into the day using daily data abstract this paper introduces a new method for identifying the simultaneity between returns and trading flows the proposed method enables us to identify the intraday interaction using daily data and provides measures of the information content of trading flows and their instantaneous response to public information and information revealed by market prices applying this method to daily data on investor types from the korea stock exchange we find significant intraday bi directional interaction between flows and returns and their latent common drivers altering some of the results of the previous literature based on cholesky assumptions thus we obtain a number of new insights concerning the behavior of investor types

time use patterns and women entrepreneurs the twentieth century saw a dramatic increase in the number of women in the labor force as well as a steady increase in the number of selfemployed women during the past three decades this increase in labor force participation represents a striking change in the allocation of women s time between work and home activities despite the growing literature examining self employed women little is known about how self employed women divide their time between work and other life activities the flexibility afforded by self employment is often regarded as a way to better balance work and home activities indeed the existing econometric studies indicate that women choose self employment primarily because of family or lifestyle factors theresa devine 1994 richard k caputa and arthur dolinsky 1998 richard j boden 1999 greg hundley 2000 yet studies outside the economics literature seem to indicate that self employed women do not necessarily experience more family satisfaction holly e buttner and dorothy p moore 1997 saroj parasuraman and claire a simmers 2001 richard demartino robert barbato and paul h jacques 2006 a source of the difference might be that the econometric studies use human capital acquisition and entrepreneurship

the real effects of financial markets the impact of prices on takeovers using mutual fund redemptions as an instrument for price changes we identify a strong effect of market prices on takeover activity the trigger effect an interquartile decrease in valuation leads to a seven percentage point increase in acquisition likelihood relative to a 6 unconditional takeover probability instrumentation addresses the fact that prices are endogenous and increase in anticipation of a takeover the anticipation effect our results overturn prior literature that finds a weak relation between prices and takeovers without instrumentation these findings imply that financial markets have real effects they impose discipline on managers by triggering takeover threats does a low market valuation make a firm a takeover target in theory if acquisition prices are related to market prices acquirers can profit from taking over a firm whose market value is low relative to its peers due either to mispricing or mismanagement and restore it to its potential indeed in practice acquirers and other investors appear to track a firm s valuation multiples for indications on the potential for acquisition and managers strive to maintain high market valuations to prevent a hostile takeover understanding whether such a link exists is important because if so this would suggest that the market is not a sideshow but rather exerts a powerful disciplinary effect on firm management as suggested by marris 1964 manne 1965 a ndjensen 1993 despite the above logic existing empirical studies on takeovers fail to systematically uncover a meaningful relationship between market valuations

window dressing by pension fund managers this paper takes a first look at investment strategies of managers of 769 pension funds with total assets of 129 billion at the end of 1989 the data show that managers of these funds tend to oversell stocks that have performed poorly relative sales of losers accelerate in the fourth quarter when funds portfolios are closely examined by the sponsors this result supports the view that fund managers window dress their portfolios to impress sponsors and suggests that managers are evaluated on their individual stock selections and not just aggregate portfolio performance this abstract was borrowed from another version of this item

portfolio performance evaluation old issues and new insights this article presents a model that provides insights about various measures of portfolio performance the model explores several criticisms of these measures these include the problem of identifying an appropriate benchmark portfolio the possibility of overestimating risk because of market timing ability and the failure of informed investors to earn positive risk adjusted returns because of increasing risk aversion the article argues that these need not be serious impediments to performance evaluation

new evidence on stock price effects associated with changes in the s p 500 index since october 1989 standard and poor s has when possible announced changes in the composition of the s p 500 index one week in advance because index funds hold s p 500 stocks to minimize tracking error index composition changes since this date provide an opportunity to examine the market reaction to an anticipated change in the demand for a stock using post october 1989 data the authors document significantly positive negative postannouncement abnormal returns that are only partially reversed following additions deletions these results indicate the existence of temporary price pressing and downward sloping long run demand curves for stocks and represent a violation of market efficiency copyright 1997 by university of chicago press

institutions and the turn of the year effect evidence from actual institutional trades abstract using a large proprietary database of institutional trades we investigate whether institutional investors drive the turn of the year toy effect institutions that engage in window dressing tax loss selling or risk shifting will contribute to the toy effect by selling small poorly performing stocks at the end of december and or buying those same stocks at the beginning of january we find abnormal pension fund selling in small stocks with poor past performance during the final trading days in december providing some support for the window dressing hypothesis however we find little evidence that institutional tax loss selling or risk shifting trading strategies contribute to toy returns furthermore stocks with no institutional trading around the year end exhibit considerably stronger toy return patterns than stocks in which institutions trade taken together our results suggest that institutions play a limited role in driving the toy effect

mutual fund herding in response to hedge fund herding and the impacts on stock prices abstract we examine whether mutual funds and hedge funds herd after each other and the associated impacts on stock prices we find strong evidence that mutual funds herd into or out of stocks following the herd of hedge funds mutual funds herding measure is positively related to last quarter s hedge fund herding in contrast hedge funds do not follow mutual funds mutual funds following of hedge funds leads to a sharp price reversal in the next quarter whereas hedge fund herding itself does not destabilize prices further a mutual fund s following intensity increases with its past performance the top 30 of mutual funds most active in following hedge funds do so persistently and drastically increase their herding subsequent to intense herding by hedge funds they are also the group driving the above price reversals overall our evidence is consistent with the reputational incentives of mutual fund herding and the associated price destabilization effects

aid dependence and the quality of governance cross country empirical tests aid dependence can potentially undermine the quality of governance and public sector institutions by weakening accountability encouraging rent seeking and corruption fomenting conflict over control of aid funds siphoning off scarce talent from the bureaucracy and alleviating pressures to reform inefficient policies and institutions analyses of cross country data in this paper provide evidence that higher aid levels erode the quality of governance as measured by indices of bureaucratic quality corruption and the rule of law these findings support the need for donors to develop less costly and less intrusive ways of disseminating state of the art knowledge on public sector reform in developing countries

does foreign aid corrupt abstract we estimate the impact of foreign aid on corruption using geographical and cultural distance to the donor countries as instrumental variables to assess causality aid decreases corruption our results are statistically and economically significant and robust to different controls

pay differences among the highly paid the male female earnings gap in lawyers salaries this article uses very detailed information on graduates of the university of michigan law school to examine male female pay differences in that population men and women in this population have virtually identical human capital on graduation from law school allowing us to examine carefully the different impact of children and work history on men s and women s careers and earnings taking time from work in order to care for children reduces wages significantly but a rich set of controls including childcare work history school performance and job setting measures still leave one fourth to one third of the earnings gap unexplained

being in someone else s shoes the role of gender in nascent entrepreneurship several studies have shown the existence of significant differences in the rate of new business creation between men and women specifically it has been shown that women are much less likely to be involved in entrepreneurship than men worldwide it is not yet understood however if such differences are the result of personal characteristics of the individual and of her economic environment or are instead the result of universal and perhaps evolutionary phenomena our empirical analysis is conducted using representative samples of population for 37 countries and a special form of bootstrapping that allows us to equalize individuals conditions and as a result analyze the choices of men and women put in identical economic environments and socio economic circumstances

how index trading increases market vulnerability the authors found that the rise in popularity of index trading assets invested in index funds reached more than 1 trillion at the end of 2010 contributes to higher systematic equity market risk more equity index trading corresponds to increased cross sectional trading commonality which precipitates higher return correlations among stocks consistent with the accelerating growth of passive trading the authors found that equity betas have not only risen but also converged in recent years

information learning and wage rates in low income rural areas in this essay we present evidence that employers in rural areas of developing countries have imperfect information with regard to the productivity of heterogeneous workers in addition to obtaining direct measures of the completeness of employer information we consider the implications of information asymmetries for the structure of casual labor markets we then evaluate the extent to which casual labor markets do in fact exhibit these attributes we find that 1 there is adverse selection out of the time rate labor market 2 employers discriminate statistically given two workers with different observed characteristics but the same actual productivity the worker from the group with the higher average productivity will have a higher wage 3 employers exhibit learning over time the extent of employer ignorance is negatively related to labor market exposure on the part of the workers and 4 calorie consumption affects productivity but is not rewarded in the time rate labor market in concluding we argue that an analysis of wage and employment patterns and the implications of these patterns for human capital investment in rural areas of developing countries that ignored the role of information problems could yield misleading conclusions

the role of governance in determining foreign aid flow composition summary we hypothesize that selective donors will use types of aid over which they have more control when providing assistance to poorly governed countries we use an original classification of project purpose codes in the aiddata dataset to categorize aid flows from the period 2004 to 2010 results from fixed effect and compositional data models provide evidence of selectivity in terms of overall aid flows a tradeoff between technical assistance and programmatic lending and a tradeoff between social sector and infrastructure projects

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

self employment and married women abstract this paper examines the determinants of self employment among married women the study uses these results to assess the impact of selectivity bias due to self employment decisions on the earnings of wage salary and self employed workers

price dynamics in a market with heterogeneous investment horizons and boundedly rational traders this paper studies the effects of multiple investment horizons and investors bounded rationality on the price dynamics we consider a pure exchange economy with one risky asset populated with agents maximizing crra type expected utility of wealth over discrete investment periods an investor s demand for the risky asset may depend on the historical returns so that our model encompasses a wide range of behaviorist patterns the necessary conditions under which the risky return can be a stationary iid process are established the compatibility of these conditions with different types of demand functions in the heterogeneous agents framework are explored we find that conditional volatility of returns cannot be constant in many generic situations especially if agents with different investment horizons operate on the market in the latter case the return process can display conditional heteroscedasticity even if all investors are so called fundamentalists and their demand for the risky asset is subject to exogenous iid shocks we show that the heterogeneity of investment horizons can be a possible explanation of different stylized patterns in stock returns in particular mean reversion and volatility clustering

cracks in the glass ceiling gender and promotion in the economics profession gender differences in promotion within the economics profession have long been a concern of the committee on the status of women in the economics profession cswep in a descriptive analysis of the aea universal academic questionnaire rebecca blank 1996 finds that hires and promotions to the associateand fullprofessor levels have averaged 4 2 and 2 7 percentage points below the share of female assistants and associates professors respectively thus women appear to be underrepresented in senior positions suggesting they may face a glass ceiling this paper uses unique panel data for american economic association aea members to examine formally whether there are differences across gender in promotion probabilities an academic labor market beyond its direct interest to economists is well suited to study possible gender differences in promotion because departments can be ranked within the profession and because professors can be ranked within a department by a welldefined promotion hierarchy a focus on academic economists offers an additional advantage in that on the job productivity can be measured directly by research output other promotion studies have had limited controls for productivity and have used cross sectional data which do not permit controls for unobserved ability e g rudolf winter ebmer and josef zweimuller 1997 failure to account for gender differences in unobserved productivity could produce biased inference prior promotion studies also have generally relied on job advancement indexes that limit the distinction between initial job assignment i e an

do demand curves for stocks slope down since september 1976 stocks newly included into the standard and poor s 500 index have earned a significant positive abnormal return at the announcement of the inclusion this return does not disappear for at least ten days after the inclusion the returns are positively related to measures of buying by index funds consistent with the hypothesis that demand curves for stocks slope down the returns are not related to s p s bond ratings which is inconsistent with a plausible version of the hypothesis that inclusion is a certification of the quality of the stock

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

aid government expenditure and aggregate welfare summary this paper tests the hypothesis that aid contributes to increasing aggregate welfare measured by infant mortality and the human development index hdi in recipient countries estimation is based on data for 104 countries over the period 1980 2000 and for subsamples of low income and middle income countries fixed effect estimates provide robust evidence that aid is associated with improved values of the welfare indicators and this effect appears to be greater in low income countries aid appears to increase welfare either directly or through the effect on growth and there is no evidence that aid operates through public spending

do corrupt governments receive less foreign aid critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies supporters argue that foreign aid can be used to reward good governments this paper documents that there is no evidence that less corrupt governments receive more foreign aid on the contrary according to some measures of corruption more corrupt governments receive more aid also we could not find any evidence that an increase in foreign aid reduces corruption in summary the answer to the question posed in the title is no

changes in institutional ownership and stock returns assessment and methodology although the relation between quarterly changes in institutional investor ownership and contemporaneous stock returns is well documented the source of the relation remains unclear because institutional ownership data are unavailable at higher frequencies in this study we develop a method to generate estimates of higher frequency covariances when one variable is observed at lower frequencies e g quarterly changes in institutional ownership and monthly stock returns our method provides evidence that institutional trading has both temporary and permanent price effects and that the latter is associated with information effects

gender differences in salary and promotion in the humanities in their annual review of academic salaries the american association of university professors observes large gender related salary differentials at doctoral level institutions male professors at the rank of full professor earn 11 4 more than women full professors data on academic labor markets from the survey of doctorate recipients to evaluate gender differences in salaries and promotion probabilities differences in employment outcomes by gender are found using two methods the oaxaca decomposition is used to examine salary differentials and duration analysis is used to estimate promotion to tenure while gender salary differences can largely be explained by academic rank substantial gender differences in promotion to tenure exist after controlling for productivity demographic characteristics and primary work activity

do existing corruption levels matter in controlling corruption cross country quantile regression estimates abstract we examine the determinants of corruption using recent cross sectional data for nearly one hundred countries while the causes of corruption have drawn economists interest in recent years our main contribution is to examine the corruption determinants throughout the conditional distribution of corruption across nations are there different causes of corruption in highly corrupt nations compared to the least corrupt countries for instance we examine whether greater democracy and more economic freedom consistently reduce corruption among the most and the least corrupt our results for the significant determinants support some findings in the literature but also provide new conclusions in many cases quantile regression estimates are quite different from those from ols regressions among the most corrupt nations larger governments and greater economic freedom do not appear to reduce corruption but greater democracy seems to alleviate it our results suggest that some current corruption control policies may be reconsidered especially among the most corrupt and least corrupt nations

why does financial strength forecast stock returns evidence from subsequent demand by institutional investors using institutional investor demand as a proxy for revisions in sophisticated investors expectations we test whether financial strength information is gradually impounded over time consistent with the gradual incorporation of information financial strength predicts both future returns and future institutional investor demand further consistent with the gradual incorporation of information more sophisticated transient high turnover institutions respond to financial strength signals prior to less sophisticated nontransient institutions a number of additional tests suggest that financial strength forecasts stock returns at least in part because it forecasts institutional demand and institutional demand drives prices the author 2012 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oup com oxford university press
