discretionary accounting choices and the predictive ability of accruals with respect to future cash flows using a sample of restatement firms and a meet or beat model to classify firms as making discretionary accounting choices for opportunistic meet or beat op mb reasons we show that originally reported earnings and accrual components are less predictive of future cash flows relative to the restated numbers we find the opposite is true for firms classified as making discretionary accounting choices for non op mb reasons we consider a number of competing explanations for these latter results our findings are most consistent with the informational hypothesis weakly consistent with conservative motivated efficient contracting hypotheses but inconsistent with opportunistic contracting and misapplication errors of gaap explanations

applying digital analysis to detect fraud an empirical analysis of us marine industry firms have tendency to window dress their financial statements by reporting earnings to achieve reference points represented by n 10 k such practice of reporting rounded earnings is likely due to 1 firms may believe that investors perceive a reported earnings of 1 99 million to be significantly less than 2 0 million and or 2 contracts between firms and stakeholders are likely to express earnings in round numbers auditors have employed more sophisticated digital analysis such as benford s law as part of their fraud detection processes this study investigated the window dressing behaviour among firms in the us marine industry the findings of the study suggest that window dressing is a significant practice among the marine firms however the extent of the pervasiveness of such behaviour is less severe among marine firms than among all publicly listed firms in the entire us economy suggesting that the quality of financial statements of marine companies is higher than the overall population of

child care prices and maternal employment a meta analysis the literature estimates for labor force participation elasticity with regard to child care prices are extensive and varying while some estimates imply substantial gains from child care subsidies others find insignificant effects to determine the causes of the variance this paper reviews and analyzes the elasticity sizes using estimates from 36 peer reviewed articles and working papers in the literature we start by reviewing the theoretical and empirical aspects related to participation elasticity with regard to child care costs paying special attention to sample characteristics methodological aspects and macro level factors we conclude by providing a meta regression using control variables based on our review of the literature to explain some of the differences between the estimates as research builds on and improves the methods and assumptions in prior works elasticity estimates have become smaller over time this decline might also be partially explained by changes in labor market characteristics in countries with high rates of part time work and very high or very low rates of female labor force participation we find elasticity rates to be smaller

do nonprofits manipulate investment returns we provide evidence that nonprofit organizations manipulate reported investment returns to avoid investment losses we find a sharp discontinuity around zero in cross sectional distribution of the rates of return on investments for tax exempt organizations rates of return are significantly more likely to be slightly positive than slightly negative this pattern is found for a wide range of nonprofit missions including religious related charities and community improvement organizations

price of high quality daycare and female employment using local variation between municipalities i analyze the degree to which the price of high quality publicly subsidized childcare affects female employment following maternity leave importantly prices are income dependent and thus likely endogenous yet by exploiting information on minimum income compensation during non employment i bypass this problem the results show that the price negatively affects employment a price increase of 1 per month decreases employment by 0 08 which corresponds to a price elasticity of 0 17 these effects prevail during the first 12 months after childbirth i also find that availability of childcare increases employment

exploiting ergodicity in forecasts of corporate profitability abstract theory suggests that competition tends to equalize profit rates through the process of capital reallocation and numerous studies have confirmed that profit rates are indeed persistent and mean reverting recent empirical evidence further shows that fluctuations in the profitability of surviving corporations are well approximated by a stationary laplace distribution here we show that a parsimonious diffusion process of corporate profitability that accounts for all three features of the data achieves better out of sample forecasting performance across different time horizons than previously suggested time series and cross sectional models as a consequence of replicating the empirical distribution of profit rates the model prescribes a particular strength or speed for the mean reversion of all returns which leads to superior forecasts of individual time series when we exploit information from the cross sectional collection of firms the new model should appeal to managers analysts investors and other groups of corporate stakeholders who are interested in accurate forecasts of profitability to the extent that mean reversion in profitability is the source of predictable variation in earnings our approach can also be used in forecasts of earnings and is thus useful for firm valuation

the effect of income taxation on labor supply in the united states the effect of income taxation on the labor supply of prime age married men and women in the united states is examined using econometric methods similar to those used in the influential work of jerry hausman male labor supply is found to be relatively invariant to the net wage and virtual income in all specifications estimated the estimated impact of taxation on the labor supply of married women depends critically on the method used to estimate the labor supply function estimated net wage and virtual income elasticities are considerably larger when data on nonparticipants are included than when the estimation is conducted conditional on hours being greater than zero

the econometrics of kinked budget constraints in the last several years a branch of applied econometrics has developed which is devoted to the development of techniques for the estimation of demand and other functions when the budget constraint is piecewise linear or kinky that is when the constraint consists of a number of segments joined together at kink points such constraints most frequently arise from government tax and transfer programs for example the federal income tax imposes a piecewise linear schedule by the use of constant marginal tax rates within brackets a problem analyzed by hausman 1981 the payroll tax in the social security system likewise generates a kinked schedule inasmuch as the marginal tax rate on earnings is zero above a certain earnings maximum federal and state transfer programs for the poor result in piecewise linear constraints because transfer benefits are taxed in the sense of a negative income tax as income rises and because that tax rate falls to zero at the kink point where an individual or family loses eligibility for the benefit altogether many government transfer programs impose additional nonlinearities by altering this tax rate by discrete amounts over the range of positive benefits as well but kinked constraints sometimes arise in nongovernment contexts a well known example being the block pricing schedule commonly set by utilities and volume discounting in general kinked budget constraints create two difficulties that have several interesting facets one difficulty is that changes in tax and transfer schedules can have unexpected effects that can be exactly the opposite in sign to those expected from economic theory examples of this phenomenon are given below the second difficulty that with which this paper is mostly concerned relates to the implications of kinked budget

labor unemployment insurance and earnings management abstract we provide new evidence that firms appear to manage long run earnings upward in order to manage rank and file employees perceptions of employment security in particular we exploit exogenous state level changes in unemployment insurance benefits and test for partial unwinding of prior upward earnings management when benefits increase consistent with the hypothesis we find a significant reduction in abnormal accruals increased recognition of special items and write downs and greater likelihood of net income reducing restatements following an increase in state level unemployment benefits a number of cross sectional results are also consistent with the hypothesis

child care and the labor supply of married women reduced form evidence this paper empirically analyzes family demands for market and nonmarket child care services and the impact of these demands on the work effort of married women the paperfirst develops a general model of child care and labor force participation the model predicts that higher wages increase the likelihood of labor force participation and that higher costs decrease the likelihood of child care utilization the paper then develops a threeequation reduced form econometric specification of the general model the equations in the specification are estimated simultaneously using 1985 data from the survey of income program participation the estimates reveal that the cost of market child care has a strong negative effect on the labor supply of married women

household childcare choices and women s work behavior in russia the author models mothers participation in the labor force their working hours and household demand for childcare in russia the model estimates the effects of the price of childcare mothers wages and household income on household behavior and well being the theoretical model yields several predictions to test these reduced form equations of the discrete and continuous household choices are estimated jointly using the method of semi parametric full information maximum likelihood this method controls for the correlation of error terms across outcomes and the correlation of error terms that can result when panel data are used the results of this analysis indicate that the extent to which mothers participate in the labor force and for how many hours depends on the costs of childcare and on what level of hourly wage is available to them and to other members of the household the author s simulations show that family allowances intended to reduce poverty do not significantly affect the household choice of childcare arrangements replacing family allowances with childcare subsidies might have a strong positive effect on women s participation in the labor force and thus could be effective in reducing poverty

is the household demand for in home services sensitive to tax reductions the french case our paper examines the impact of tax reductions on the demand for services in the home for that purpose we estimate a structural model of demand for such services by using household individual data collected by insee paris in 1996 in this model the net hourly wage paid to the domestic employee the household preferences for consumption of in home services and the decision to take advantage of the tax reduction are considered as endogenous variables estimation of the econometric model uses the fact that some households are observed to consume domestic services and to take advantage of the tax reduction while others either consume such services but do not take advantage of the tax reduction or do not consume these services at all its identification relies on an exclusion restriction resulting from the tax credit schedule results show that the probability of consuming in home services increases with age and income a 10 increase in the tax reduction would increase from 45 9 to 50 8 the proportion of households benefiting from the tax reduction among those who consume paid in home services moreover 13 5 of households who do not actually consume such services would do so after the 10 increase in the tax reduction these simulated variations would mainly concern high income households

does meeting earnings expectations matter evidence from analyst forecast revisions and share prices this paper investigates whether the market rewards firms meeting current period earnings expectations and whether any such reward reflects the implications of meeting expectations in the current period for future earnings or reflects a distinct market premium we document that abnormal annual returns are significantly greater for firms meeting expectations controlling for the information in the current year s earnings we then test whether firms meeting expectations experience higher returns simply because their expected future earnings are also higher we find firms meeting expectations have significantly higher earnings forecasts and realized earnings than firms that do not we find that controlling for these higher future earnings firms meeting expectations in one or two years do not receive a greater valuation than their fundamentals would suggest we find however that the market assigns a higher value to firms that meet expectations consistently controlling for an estimate of the firm s fundamental value

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

maternal labor supply and the availability of public pre k evidence from the introduction of prekindergarten into american public schools in the 1980s and 1990s many states began to provide funding for prekindergarten programs for the first time this paper takes advantage of the staggered timing in program funding to investigate the effect that increased availability of prekindergarten programs has on the labor supply of mothers with four year olds i find that mothers with a four year old and no younger children were significantly more likely to be in the labor force and employed once prekindergarten became available and that these effects were largest for single low educated mothers and married college educated mothers mothers with a four year old and other younger children were also significantly more likely to be in the labor force and employed although these effects were smaller in magnitude and not significant for specific subpopulations

efficiency analysis of german electricity distribution utilities non parametric and parametric tests this study applies non parametric and parametric tests to assess the efficiency of electricity distribution companies in germany traditional issues in electricity sector benchmarking are addressed such as the role of scale effects and optimal utility size as well as new evidence specific to the situation in germany labour capital and peak load capacity are used as inputs and units sold and the number of customers as output the data cover 307 out of 553 german electricity distribution utilities a data envelopment analysis dea is applied with constant returns to scale crs as the main productivity analysis technique whereas stochastic frontier analysis sfa with distance function is the verification method the results suggest that returns to scale play but a minor role only very small utilities have a significant cost advantage low customer density is found to affect the efficiency score significantly in particular in the lower third of all observations surprisingly east german utiliti

divergence in technical efficiency of electric utilities evidence from the sapp abstract this paper investigates the convergence pattern of technical efficiency of the south africa power pool sapp utilities over the period april 2003 march 2010 by means of parametric and non parametric techniques technical efficiency scores are computed via both stochastic frontier analysis and data envelopment analysis mixed results are obtained from the neoclassical convergence approaches in addition distribution dynamics methods reveal some evidence of club formation and this result is supported with the occurrence of divergence taken as a whole technical efficiency is found to diverge among the utilities operating in the power pool

on the evidence of a working spouse penalty in the managerial labor market this analysis of march 1993 current population survey data suggests that managers with working wives earn lower wages than their counterparts with non working wives the labor supply decisions of managers wives appear to be unaffected by that is exogenous with respect to their husbands wages in contrast there is evidence that the labor supply decisions of non managers wives are affected by their husbands wages and when the analysis takes account of that endogeneity it is found that non managers do not suffer a working spouse penalty the analysis also highlights some important issues related to the use of instrumental variables

two sided learning and the ratchet principle i study a class of continuous time games of learning and imperfect monitoring a long run player and a market share a common prior about the initial value of a gaussian hidden state and learn about its subsequent values by observing a noisy public signal the long run player can nevertheless control the evolution of this signal and thus affect the market s belief the public signal has an additive structure and noise is brownian i derive conditions for an ordinary differential equation to characterize equilibrium behavior in which the long run player s actions depend on the history of the game only through the market s correct belief using these conditions i demonstrate the existence of pure strategy equilibria in markov strategies for settings in which the long run player s flow utility is nonlinear the central finding is a learning driven ratchet principle affecting incentives i illustrate the economic implications of this principle in applications to monetary policy earnings management and career concerns

the information content of losses abstract this study hypothesizes that because shareholders have a liquidation option losses are not expected to perpetuate they are thus less informative than profits about the firm s future prospects the results are consistent with the hypothesis they also show that the documented increase in the earnings response coefficent as the cumulation period increases appears to be due exclusively to the effect of losses the liquidation option effect extends to profitable cases where earnings are low enough to make the option attractive alternating explanations for the low informativeness of losses such as mean reversal of earnings are not supported by the tests

women s labour force participation and child care in romania abstract this paper models household demand for childcare and mothers labour force participation in romania the model estimates the effects of the price of childcare mothers wages and household characteristics on household behaviour with respect to childcare and maternal employment we find that both the maternal decision to become employed and the decision to use out of home care are sensitive to the price of childcare a decrease in the price of care can increase the number of working mothers and thus can reduce poverty in some households we also find that the potential market wage of the mother has a significant positive effect on the decision to purchase market care and on the decision to engage in paid employment the level of household non wage income has little effect on maternal employment and on the demand for childcare

debt covenant violation and manipulation of accruals abstract this paper examines the abnormal accruals of a sample of 94 firms that reported debt covenant violations in annual reports we expect debt covenant restrictions to influence accounting choices in the year preceding and the year of violation time series and cross sectional models are used to estimate normal accruals in the year prior to violation both models indicate that abnormal total and working capital accruals are significantly positive in the year of violation there is evidence of positive abnormal working capital accruals after controlling for management changes and auditor going concern qualifications

efficiency and regulation of the slovenian electricity distribution companies abstract the slovenian energy law adopted in 1999 has opened the internal market to competition up to 64 of the final consumption the opening of the internal market to foreign competition is envisaged for 2003 with regard to the methodology of price regulation the energy law introduces the price cap regulation which aims to give firms incentive for cost reduction to provide information for effective price regulation we estimated a cost frontier function on a sample of slovenian electricity distribution utilities over the 1991 2000 period the estimated efficient frontier could be used by slovenian regulatory agency as a benchmark to regulate network access prices our results show that slovenian distribution companies are cost inefficient we have also proved the presence of increasing returns to scale with most utilities not achieving the minimum efficient scale thus the slovenian regulatory authority should consider how to induce mergers of small electricity distribution utilities into larger units

child care costs as a barrier to employment for single and married mothers because women typically serve as primary care providers for their children female labor force participation behavior is likely to be affected significantly by the costs associated with replacing maternal care with nonmaternal care while some evidence of this phenomenon exists in the economics literature discrepancies across studies make it difficult to provide conclusive evidence of the employment effects of these child care costs this paper uses an improved sipp survey design to present new evidence regarding the degree to which child care prices impede mothers employment behavior with additional evidence of the difference in these elasticities across marital status empirical technique and equation specification this permits linking this paper to the existing evidence drawing the conclusion that child care prices impede mothers employment behavior significantly with single mothers exhibiting less responsiveness in their labor force participation behavior to child care price changes than marri

women s career choices social norms and child care policies our model explains the observed gender specific patterns of career and child care choices through endogenous social norms we study how these norms interact with the gender wage gap we show that via the social norm a couple s child care and career choices impose an externality on other couples so that the laissez faire is inefficient we use our model to study the design and effectiveness of three commonly used policies we find that child care subsidies and women quotas can be effective tools to mitigate or eliminate the externality parental leave however may even intensify the externality and decrease welfare

the econometrics of piecewise linear budget constraints a survey and exposition of the maximum likelihood method in this article maximum likelihood techniques for estimating consumer demand functions when budget constraints are piecewise linear are exposited and surveyed consumer demand functions are formally derived under such constraints and it is shown that the functions are themselves nonlinear as a result the econometric problems in estimating such functions are exposited and the importance of the stochastic specification is stressed in particular the specification of both unobserved heterogeneity of preferences and measurement error econometric issues in estimation and testing are discussed and the results of the studies that have been conducted to date are surveyed

joint labor supply and childcare choice decisions of married mothers this paper examines the impact of childcare prices and wage rates on the joint employment and childcare mode center sitter relative and husband choice decisions of married mothers by estimating both a mixed logit and universal logit choice model data are drawn from the 1988 canadian national child care survey and the 1988 labour market activity survey the estimation results show that wages have a positive impact on the probability of choosing any of the working states and that childcare prices for center sitter and relative care reduce the probability of working and using each respective mode of care sensitivity analyses reveal that the wage elasticity for employment is fairly robust across model specifications while the own price elasticity of childcare is sensitive to model specification differing identifying assumptions in the estimation of childcare price equations and sample selection the simulation results show that differences exist in the degree to which government subsidies in the form of wage subsidies targeted childcare subsidies or unconditional childcare subsidies impact on labor supply decisions and decisions to substitute across different modes of care by those mothers already in the labor market

the sensitivity of an empirical model of married women s hours of work to economic and statistical assumptions this study undertakes a systematic analysis of several theoretic and statistical assumption s used in many empirical models of female labor supply using a singl e data set psid 1975 labor supply data the author is able to replic ate most of the range of estimated income and substitution effects fo und in previous studies in this field he undertakes extensive specif ication tests and finds that most of this range should be rejected du e to statistical and model misspecifications the two most important assumptions appear to be the tobit assumption used to control for sel f selection into the labor force and exogeneity assumptions on the wi fe s wage rate and her labor market experience copyright 1987 by the econometric society

earnings management behaviors under different monitoring mechanisms the case of islamic and conventional banks abstract we investigate the impact of organizational religiosity on the earnings quality of listed banks in the middle east and north africa region we analyze islamic banking institutions which operate within strict religious norms and extended accountability constraints and compare them with their conventional counterparts during 2008 2013 we find that islamic banks are less likely to manage earnings and that they adopt more conservative accounting policies based on these findings we argue that religious norms and moral accountability constraints in these organizations have a significant impact on financial reporting quality and agency costs which have implications for both regulators and market participants

earnings quality evidence from the field abstract we provide insights into earnings quality from a survey of 169 cfos of public companies and in depth interviews of 12 cfos and two standard setters cfos believe that i above all high quality earnings are sustainable and repeatable specific characteristics include consistent reporting choices backing by actual cash flows and absence of one time items and long term estimates ii about 50 of earnings quality is driven by non discretionary factors such as industry and macro economic conditions iii in any given period about 20 of firms manage earnings to misrepresent economic performance and for such firms 10 of eps is typically managed iv earnings manipulation is hard to unravel from the outside but peer comparisons and lack of correspondence between earnings and cash flows provide helpful red flags in addition cfos disagree with current standard setting on a number of issues including the sheer number of promulgated rules the top down approach to rule making the neglect of the matching principle and the emphasis on fair value accounting they indicate that a rules based culture makes the audit function centralized and mechanical and hinders the development of audit professionals a summary impression from our work is that cfos view earnings quality as more of a single and unconditional characteristic in contrast to current research where measures of earnings quality are strongly conditional on the decision setting this cfo view is related to their idea of one number a single earnings metric that shapes both their interactions with external stakeholders and internal decision making

do hedge fund managers misreport returns evidence from the pooled distribution we find a significant discontinuity in the pooled distribution of monthly hedge fund returns the number of small gains far exceeds the number of small losses the dis continuity is present in live and defunct funds and funds of all ages suggesting that it is not caused by database biases the discontinuity is absent in the 3 months culminating in an audit suggesting it is not attributable to skillful loss avoidance the discontinuity disappears when using bimonthly returns indicating a reversal in fund performance following small gains this result suggests that the discontinuity is caused at least in part by temporarily overstated returns

the econometrics of nonlinear budget sets traditional empirical analysis of consumer demand has usually made the assumption of linear budget sets that is the consumer is assumed to purchase any desired quantity at a constant price subject to a budget constraint the major exception to this framework is the analysis of demand when some goods are rationed 2 in the rationed case the price is constant up to a quantity limit in contrast to the rationed case here i consider the situation where the price varies with the amount of the good purchased empirical situations with nonconstant prices come readily to mind and of course they have received much recent attention from theorists since mirrlees 44 paper on optimal nonlinear taxation the following examples are meant to give a partial listing of cases when nonlinear budget sets occur i electricity prices many electric utilities engage in declining block pricing that is the marginal price of successive kwh s of electricity decrease at a given number of points determined by total demand thus the budget set is piecewise linear houthakker 36 was the first to propose an approach to this problem taylor 51 analyzes the problem at length and hausman kinnucin and mcfadden 31 use an instrumental variables estimator to provide consistent estimates of the demand function

how efficient are african electricity companies evidence from the southern african countries this paper is a first attempt at documenting efficiency levels in africa s electricity firms their evolution and the sources of this evolution the analysis is based on a sample of 12 operators providing services in the 12 country members of the southern africa power pool we focus on the changes in total factor productivity tfp of the largest operators in each country between 1998 and 2005 we then rely on a data envelopment analysis dea decomposition to identify the sources of the changes in tfp the results suggest fairly comparable levels of efficiency in the region and performance levels and evolution quite independent of the degree of vertical integration the presence of a private actor or the main sources of energy supply the analysis suggest that although the companies have not made significant improvements during the period of analysis in using their capital and human assets they have done much better in adopting better technologies and better commercial practices no clear correlation could be associated with the adoption of reforms during the last decade and data limitations impede a more refined assessment of the impact of reforms on efficiency at this stage

a comprehensive review of data envelopment analysis dea approach in energy efficiency the main aim of this review article is to review of dea models in regarding to energy efficiency this paper reviewed and summarized the different models of dea that have been applied around the world to development of energy efficiency problems consequently a review of 144 published scholarly papers appearing in 45 high ranking journals between 2006 and 2015 have been obtained to achieve a comprehensive review of dea application in energy efficiency accordingly the selected articles have been categorized based on year of publication author s nationalities scope of study time duration application area study purpose results and outcomes results of this review paper indicated that dea showed great promise to be a good evaluative tool for future analysis on energy efficiency issues where the production function between the inputs and outputs was virtually absent or extremely difficult to acquire

childcare subsidies wages and employment of single mothers this paper develops and estimates a model for the choice of part time and full time employment and the decision to pay for childcare among single mothers the results indicate that a lower childcare price and a higher full time wage rate both lead to an increase in overall employment and the use of paid childcare the part time wage effects are found to be too small to have significant behavioral implications an analysis of cost effectiveness indicates that the additional hours of work generated per dollar of government expenditure is larger for a childcare subsidy than a wage subsidy

earnings manipulation pension assumptions and managerial investment decisions managers appear to manipulate firm earnings through their characterizations of pension assets to capital markets and alter investment decisions to justify and capitalize on these manipulations managers are more aggressive with assumed long term rates of return when their assumptions have a greater impact on reported earnings firms use higher assumed rates of return when they prepare to acquire other firms when they are near critical earnings thresholds and when their managers exercise stock options changes in assumed returns in turn influence pension plan asset allocations instrumental variables analysis indicates that 25 basis point increases in assumed rates are associated with 5 percent increases in equity allocations

marital status and full time part time work status in child care choices using recent sipp data this study estimates two econometric models to study the differences in the effect of child care costs on employment status and differences in the mode of child care used controlling for employment status for both married and single women full time employment is more elastic with respect to changes in the price of child care than part time employment and employment elasticities are larger for single than married mothers in the model of child care modal choice we find that an increased probability of full time employment is associated with an increase in the use of centre care for both married and single mothers and that price elasticities of modal choice are larger for single than married mothers

tax credits labor supply and child care we explore the impact of the child care tax credit in the u s income tax system on the labor supply decisions of married women with young children by incorporating the cost of child care into a st

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

child care costs and the employment decision of women canadian evidence the authors estimate the joint decision for women with preschool children to engage in paid employment and to purchase market forms of child care the results confirm those found in most u s studies indicating that child care costs exert a significant negative effect on the labor supply of women with children and on their decision to purchase child care as well the expected wage of the mother exerts a significant positive impact on both the decision to purchase market forms of child care and the decision to engage in paid unemployment

the allowance for uncollectible accounts conservatism and earnings management we study the interrelation between conservatism and earnings management by examining the allowance for uncollectible accounts and its income statement counterpart bad debt expense we find that the allowance is conservative and that it has become more conservative over time conservatism may however facilitate earnings management we find that firms manage bad debt expense downward and even record income increasing bad debt expense to meet or beat analysts earnings forecasts and that conservatism accentuates the extent to which firms manage bad debt expense further we find that firms manage bad debt expense downward by drawing down previously recorded over accruals of bad debt expense that have accumulated on the balance sheet an implication of our study is that tighter limits on the amount by which firms are permitted to understate net assets may reduce their ability to manage earnings

electricity wholesale market prices in europe convergence abstract this paper tests the hypothesis that the ongoing restructuring process in the european electricity sector has led to a common european market for electricity based on a principal component analysis pca of wholesale electricity prices in 2002 2006 we reject the assumption of full market integration for several pairs of countries the weaker hypothesis of bilateral convergence is accepted based on unit root tests kpss and adf and a convergence test based on filtered pairwise price relations this indicates that the efforts to develop a single european market for electricity were so far only partially successful we show that the daily auction prices of scarce cross border transmission capacities are insufficient to explain the persistence of international price differentials empirically our findings confirm the insufficiency of explicit capacity auctions as stated in the theoretical literature

the effects of grants in aid on state and local expenditures abstract this paper develops econometric methods to estimate the effect of the piecewise linear budget constraints created by grant formulas in which the subsidy rate is not constant over expenditures e g closed end grants the methods are applied to the afdc program the results show that because of the kinked nature of the grant formula 1 the present federal formula actually increases cross state inequality in afdc benefits 2 several subsidy rates in the formula actually reduce benefits and 3 the so called flypaper effect disappears

employment and child care choices in canada and the united states in this paper we examine employment and child care choices of two parent families with young children in the united states and canada using a pooled data set based on recent national surveys in each country we find that the employment and child care choices of canadian families are similar to those of u s families estimates of a model of employment and child care choices indicate significant effects of child care subsidies child care prices and wage rates on employment and child care choices however none of these factors helps to explain the differences in employment and child care choices between the two countries ce memoire examine le choix de l emploi et du soin des enfants dans les familles ou il y deux parents aux etats unis et au canada en utilisant des donnees d etudes recentes dans les deux pays il appert que les choix des familles canadiennes sont semblables a ceux des familles americaines les calibrations d un modele de ces choix montrent les effets significatifs des subventions au soin des enfants du prix des soins des enfants et des taux de salaires sur ces choix cependant aucun de ces facteurs n explique les diffrences dans les patterns de choix entre les deux pays

the world per capita electricity consumption distribution signs of convergence abstract considering residential per capita electricity consumption as one of the most suitable economic welfare indicators the aim of this paper is to explore worldwide differences on this variable over the period 1980 2007 the paper adds to the standard practice of and convergence analysis by tracking the external shape and time evolution of the entire distribution applying nonparametric techniques density functions and stochastic kernels to a sample of 98 countries the main finding is that a weak process of electricity consumption convergence has taken place this reduction of disparities is clearly related to at least three issues firstly the rapid economic changes experienced by some developing countries secondly the energy conservation policies implemented by most developed countries following the first oil shock and thirdly the growing awareness on energy issues in rich countries notwithstanding this the ergodic distribution on per capita electricity consumption indicates that large cross country disparities will persist in the long run

distribution dynamics of co2 emissions this paper uses nonparametric methods to examine the convergence in co2 emissions per capita on a sample of 100 countries for the period 1966 1996 industrial countries show a convergence pattern however there is little evidence of convergence for the whole sample

a temporal analysis of earnings surprises profits versus losses i show that median earnings surprise has shifted rightward from small negative miss analyst estimates by a small amount to zero meet analyst estimates exactly to small positive beat analyst estimates by a small amount during the 16 years 1984 to 1999 i show that a rightward temporal shift in median surprise from negative to positive describes earnings but neither profits nor losses median profit surprise shifts within the positive quadrant from zero to one cent per share median loss surprise shifts within the negative quadrant from extreme negative about 33 cents per share to zero i show that the median surprise for profits exceeds that for losses in every year i document significant positive temporal trends in both meet and beat analyst estimates for both profits and losses but i find a greater frequency of profits that either meet or beat analyst estimates in every year i find a significant positive temporal trend in positive profits that are a little bit of good news and a significant negative temporal trend in managers who report losses that are an extreme amount of bad news my results are robust to the four internal validity threats i consider namely temporal changes in 1 analyst forecast accuracy 2 the mix of earnings of one sign preceded by earnings of another sign four quarters ago 3 the timeliness of the most recent analyst forecast and 4 the i b e s definition of actual earnings i find that managers of growth firms are relatively more likely than managers of value firms to report good news profits i show that when they do report positive profit surprises managers of growth firms are more likely to report a little bit of good news in every year

child care costs and family labor supply this paper presents a theoretical and empirical analysis of the effects of child care costs on family labor supply and the demand for market child care the model is a framework for cross section estimation of the effects of child care costs on labor supply and child care use it applies to households having young children requiring continuous care and in which both the mother and 1 other potential child care provider are present the 3 potential sources of child care are the mother the potential informal provider and the market using data from the 1980 baseline household survey of the employment opportunity pilot projects this empirical analysis uses a subsample of 6170 households in which there is a married woman under age 45 with her spouse present at the time of the survey at least 1 child under age 14 and nonmissing data on key variables results show that 1 higher market child care costs discourage women from working even when an informal source of care is available indicating that such informal care is an imperfect substitute for market care 2 a higher wage rate for the mother encourages her to work thus a higher wage rate increases the probability of using market child care 3 the number of children requiring care has a negative impact on the probability of the women working with the largest impact caused by younger children 4 nonwage income has a negative impact on the probability of the woman working and 5 black women are more likely to work than whites and are statistically more likely than whites to use market child care if they do work this family labor supply model predicts that the cost of market child care will affect household decisions on labor supply and child care use estimates of a qualitative choice model provide strong confirmation that child care costs affect such decisions the responsiveness of the labor supply of mothers to child care costs demonstrated in this study indicate that such subsidies do have their intended effect of encouraging labor supply the fact that a large proportion of current child care subsidies benefit primarily middle and upper income families via the income tax credit suggests that the labor supply effets of such subsidies may in practice be stronger for less needy families than for low income families employer subsidized child care may become an increasingly popular tool for attracting mothers into the labor force

a structural model of labor supply and child care demand this paper specifies and estimates a structural model in which the decision to purchase market child care and the quality purchased is made simultaneously with the employment decision of the mother separate analyses are performed for married mothers and single mothers the structural estimates are used to simulate the effects and costs of changes in the federal child care tax credit the simulations indicate that a refundable child care tax credit would distribute child care benefits more equally across the population by increasing the shares of subsidies received by low income families and would induce a considerable increase in expenditures on market child care labor supply also increases but by considerably less than child care expenditures a surprising result is that despite large increases in child care

public schooling for young children and maternal labor supply as policy makers have sought to reduce the welfare rolls by increasing labor supply among single mothers much attention has been given to the possible role of expanded child care subsidies including direct provision of public preschool at the same time public interest in child care subsidies for two parent households is high for example former vice president gore not long ago proposed to make high quality pre school fully available to every family for every child in every community in america albert gore 1999 in this paper i use 1980 census data to estimate the effect of public school enrollment for a woman s five year old on measures of labor supply and public assistance receipt this approach has two advantages first i am able to estimate the effect of a large implicit child care subsidy 1 second because public kindergarten is universally available to all age eligible children where it is provided selection problems related to means testing do not arise a difficulty with public school enrollment arises because parents may choose to hold their children back a year or enroll them in private school i deal with this issue by using five yearold s quarter of birth qob variables as instruments for public school enrollment status this strategy works because parents ability to enroll a child in public kindergarten in the academic year when the child turns five typically depends on the calendar date of the child s birth 2 in most states children born in the second quarter april 1 june 30 of 1974 will have been eligible to start kindergarten in the fall of 1979 while children born in the first quarter january 1march 31 of 1975 generally will not eligibility for children born between july 1 and december 31 1974 depends on the rules where they live 3

should day care be subsidized in the presence of distortionary taxes on labor can subsidies on childcare flnanced by a further increase in taxes raise welfare by encouraging women with small children to work we approach this question in two difierent ways first we consider a set of stylized models where we prove analytically that under some conditions the ramsey optimal policy consists in making childcare expenses tax deductible then we construct a calibrated stochastic dynamic life cycle model of household decision making designed to capture some facts about labor supply in germany we flnd that the welfare gains associated with subsidizing childcare are considerable and that the maximum gains are realized when childcare is subsidized to an even greater extent than what tax deductibility implies

earnings management the shapes of the frequency distributions of earnings metrics are not evidence ipso facto we provide evidence that the shapes particularly around zero of the frequency distributions of earnings metrics examined in the extant earnings management literature are affected by 1 deflation using for example price or market capitalization 2 sample selection criteria that lead to differential inclusion exclusion of observations to the left of zero versus observations to the right of zero implicit in studies focusing on firms followed by i b e s and explicit in studies partitioning on a variable differing between loss observations and profit observations 3 differences between the characteristics of observations to the left of zero and observations to the right of zero such as market pricing and analyst optimism pessimism or 4 a combination of these factors since the shapes of the frequency distributions of earnings metrics at zero are likely due to one of the above effects we conclude that the shapes cannot be used as ipso facto evidence of earnings management
