the changing time series properties of earnings cash flows and accruals has financial reporting become more conservative abstract this paper documents changes in the patterns of earnings cash flows and accruals over the last four decades in the absence of a generally accepted definition of conservatism a number of measures of reporting conservatism are identified and examined these measures rely on the accumulation of nonoperating accruals the timeliness of earnings with respect to bad and good news characteristics of the earnings distribution and the market to book ratio the patterns are consistent with an increase in conservative financial reporting over time the findings have implications for accounting standard setting regulation of financial information and financial statement analysis

fiscal policy expectation traps and child labor i introduction child labor is widespread in the contemporary world in fact the international labor organization ilo estimates that 246 million of the world s children aged 5 17 or 16 are child laborers most living in developing countries 1 recently there has been renewed interest in this topic among economists which has led to a series of theoretical studies with the aim of better understanding the causes and consequences of child labor in order to help guide appropriate policy responses as in grootaert and kanbur 1995 basu 1999 and basu and tzannatos 2003 for useful literature surveys typically theoretical models designed to address the important policy issues surrounding child labor posit that a family s decision to send a child to the labor market is taken only as a last resort in order to escape the dire consequences of poverty for example basu and van 1998 baland and robinson 2000 show that this response on the part of the family may be stronger in a dynamic setting because contracts between children and adults are not self enforcing and capital markets are incomplete 2 in this case an adult decision maker may not only send their children to work to escape poverty in the present but do so to escape poverty in the future as well this decision will hinder a child s ability to accumulate human capital and can lead to persistent cycles of poverty and child labor across generations 3 we begin by showing that a benevolent government can address the incidence of child labor that results from the non enforceability of intergenerational contracts and incomplete capital markets through the appropriate use of fiscal policy and that this policy is pareto improving it is then shown that if society s confidence in their government is incomplete this lack of confidence can render the same fiscal policy ineffective in other words if households do not believe that the government will follow through on their policy promise then in fact it is quite possible that the government will not be able to follow through on their promise as a result of these beliefs 4 this self reinforcing nature of fiscal policy in the presence of uncertainty can leave a country in an expectations trap with a low level of human capital and child labor 5 to formally demonstrate this fiscal policy expectations trap hypothesis we employ a three period overlapping generations model in which child labor exists 6 this stylized setup will keep the dynamics manageable and allow us to highlight the effects of uncertainty also within this framework we introduce a missing intergenerational contracts market in conjunction with a human capital production function that exhibits a threshold with respect to parental human capital which gives rise to two locally stable steady states there is a good equilibrium where there is a relatively high level of parental human capital which results in a high level of income and no child labor and there is a bad equilibrium where there is a relatively low level of parental human capital which results in a low level of income and positive child labor this low income child labor equilibrium is the standard poverty trap scenario that typically exists in a deterministic economy with multiple equilibria it is then shown that a benevolent government can replicate the missing intergenerational contracts market with a pay as you go social security program thereby eliminating this component of child labor in an economy with perfect foresight in addition it is also shown that this policy is pareto improving in the sense that all generations are strictly better off under this policy except the initial old who are no worse off the dynamics of this social security program are intuitive if child labor is one possible mechanism adults can use to redistribute resources from their children then the government can reduce this incentive by announcing a social security program that will begin during the current adults old age an institutional intergenerational contract

an empirical assessment of the residual income valuation model abstract this paper provides an empirical assessment of the residual income valuation model proposed in ohlson ohlson j a 1995 earnings book values and dividends in security valuation contemporary accounting research 11 661 687 we point out that existing empirical research relying on ohlson s model is similar to past research relying explicitly on the dividend discounting model we establish that the key original empirical implications of ohlson s model stem from the information dynamics that link current information to future residual income our empirical results generally support ohlson s information dynamics however we find that our empirical implementation of ohlson s model provides only minor improvements over existing attempts to implement the dividend discounting model by capitalizing short term earnings forecasts in perpetuity

optimal social security in a dynastic model with investment externalities and endogenous fertility this paper studies optimal pay as you go social security with investment externalities positive bequests and endogenous fertility with an investment externality a competitive solution without social security suffers from under investment in capital and over reproduction of population we show the existence of time consistent optimal social security that improves welfare by reducing fertility and increasing capital intensity we also illustrate numerically that a small degree of this externality can justify the observed high ratios of social security spending to gdp

a positive theory of social security based on reputation we construct a general equilibrium model in which a pay as you go social security system can be adopted and sustained as a political and economic equilibrium we alalyze the welfare implictions of this system and compare general equilibrium welfare measure to the commonly used notion of actuarial fairness

union negotiations and corporate policy a study of labor concessions in the domestic steel industry during the 1980s abstract this paper studies managerial compensation financial reporting and dividend policies of the seven major domestic steel producers during requests for union concessions substantial layoffs reported losses and sacrifices by nonunion stakeholders buttressed managers case for union concessions from 1980 to 1988 sample firms reduced their work force by about 300 000 almost two thirds and annual wage payments from 16 1 to 8 6 billion reported income is lower during union negotiations controlling for cash flows as is managerial pay with average ceo salary plus bonus declining 18 dividend reductions and white collar pay cuts are substantial pervasive and clustered during union negotiations

endogenous transfer institutions in overlapping generations abstract we characterize the set of equilibrium transfers between overlapping generations when transfer institutions are endogenous in stationary economies pareto improving transfers require institutions cost as much to construct as they convey even if less costly institutions exist that make the same transfer if institutions can be built upon they may cost less and convey more but transfers may become excessive interpreting such institutions as social security we introduce private saving with time social security crowds out savings still the potential to save limits any excess transfer endogenous costly to create gold money institutions are examined and the role of compulsion in evolving to costless to create fiat currency detailed

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

socially optimal social security and education subsidization in a dynastic model with human capital externalities fertility and endogenous growth abstract this paper considers socially optimal government policies in a dynastic family model with physical capital human capital endogenous fertility and positive spillovers from average human capital such spillovers reduce human capital investment but raise fertility from their social optimum we first characterize the social optimum with a non convex feasible set due to the quantity quality tradeoff concerning children we then show that social security and education subsidization together financed by labor income taxes can fully eliminate the efficiency losses of the spillovers and achieve the social optimum under plausible conditions however none of the policies can do so alone

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

increasing longevity and social security reforms a legislative procedure approach abstract increasing longevity causes an upward trend in the dependency ratio in many countries this raises concerns about the financial sustainability of social security schemes and reform proposals and initiatives abound it is shown that a fundamental policy choice inevitably arises since a given social security system cannot be maintained by simply indexing pension ages to longevity the political reform process is analysed using the so called legislative procedure when longevity increases the retirement age is raised more than proportionally to the increase in longevity but the young also make larger transfers to the old

voting on pensions a survey abstract the paper presents a nonexhaustive survey of the literature designed to explain emergence size and political sustainability of pay as you go pension systems it proposes a simple framework of analysis a small open two overlapping generation economy model around which some variants are displayed dictatorship of the median voter is assumed the text is organized to answer the following questions i do political equilibria with payg pension schemes exist ii why do they emerge iii what are the conditions for the participation constraint of the pension game to be verified and finally iv what is the size of the pension system chosen by the median voter and how is this size influenced by an exogenous e g demographic shock

commercial policy with altruistic voters in public discussions of policy evidence that import competing sectors earn low or falling incomes is often used to argue for protection this paper rationalizes the apparent effectiveness of this argument in both direct and indirect democracies in direct democracies a small degree of voter altruism leads to protection in the specific factors model when the import competing sector earns little similarly voter altruism creates an incentive in representative democracies for self interested parties to present evidence to legislators on the income of import competing factors this leads to a theory in which campaign contributions buy access to legislators rather than buy votes

distributional effects of general population prescription drug programs in canada canadian household prescription drug expenditures are studied using the statistics canada family expenditure survey masterfiles for periods that include the introduction of provincial general population prescription drug programs budget shares for non senior households are examined over time using non parametric regres sion parametric difference in difference techniques and quantile regression methods the evidence suggests that while program effects are muted when there are high deductibles a non senior prescription drug subsidy is more redistributive than an equal cost proportional income transfer in part because of differential private health insurance coverage by income this is in contrast to previous evidence on canadian senior prescription drug subsidies jel classification 118 j42

dynamic efficiency in the gifts economy abstract in the standard analysis of overlapping generations economies with gifts from children to parents each generation takes the actions of other generations as given the resulting equilibrium is dynamically inefficient in reality however parents realize that children will respond to higher parental saving by reducing gifts for a broad class of gift economies this implicit tax on saving pushes the equilibrium to dynamic efficiency this result reestablishes the potential relevance of the gift model to the us economy renders moot an important part of the ricardian equivalence debate and provides a motivation for a type of social security system

how has the financial crisis affected earnings management a european study the article aims to investigate whether and how in the european union eu the burst of the 2008 financial crisis affected misrepresentation of financial information due to earnings management by analysing a sample of 11 844 firm year observations listed in the eu over the period 2006 2012 an event study methodology allows us to calculate and compare country by country abnormal accruals over the estimation period and over the event period our findings validate our research hypothesis and suggest a decrease of misrepresentation in the large majority of the european countries after the burst of the financial crisis the results take part in the debate in the accounting literature about the change of earnings management over a financial crisis and have several implications for standard setters and regulators that could learn how the common incentives of entities to attract potential investors during a crisis could lead them to provide a high quality financial reporting

productivity growth and the political economy of social security the present paper provides an analysis of unfunded social securityas the outcome of a public decision making process in an endogenousgrowth economy it employs a model in which there is a non monotonic relationship beween productivity growth and the scale ofpublic intergenerational redistribution the paper shows thatalthough unfunded social security need not harm growth in general it is likely to harm growth in a democracy this effect isreinforced by population aging

public pensions choices for the future abstract the purpose of this paper is to analyze to what extent pay as you go government mandated pensions can provide adequate retirement income to future generations this question is particularly relevant at times when the financial viability of public pensions is threatened by demographic aging and possibly declining productivity and when more importantly there is little consensus as to why those programs exist as they are that is mandatory public and unfunded the gist of our argument is that an aging population particularly if combined with declining productivity would jeopardize the financial and political viability of public pensions if individuals behavior doesn t adjust to this new reality and public authorities don t adopt the appropriate reforms as to mandatory retirement age payroll taxes and benefits structure among key individual decisions we focus on saving labor participation retirement education migration and fertility we consider how sensitive each of these is to changes in the environment and to changes in policy parameters then we turn to a number of issues unsolved either because of analytical complexity or because they arise from new realities

reform support in times of crisis the role of family ties we argue that an important determinant of voters support for economic reform is the strength of family ties while the crisis hypothesis predicts that crises facilitate reform we show in a political economy model that this relation can break down and even reverse when agents take into account the effect of reform on their family members applied to southern european countries with strong family ties the model rationalizes why the extremely high youth unemployment following the great recession has not led to more substantial labor market reforms in such countries austerity might block rather than foster additional structural reforms

the articulation of price earnings ratios and market to book ratios and the evaluation of growth this paper interprets the price earnings ratio pie and the marketto book ratio pib and describes how they articulate it also describes the role of book rate of return on equity the ratio of their denominators in the determination of the ratios and the relation between them although both are reported regularly there is not a common understanding of these issues for example the pie ratio has been interpreted as an earnings growth indicator cragg and malkiel 1982 and litzenberger and rao 1971 a risk measure ball 1978 and an earnings capitalization rate graham dodd and cottle 1962 boatsman and baskin 1981 and alford 1992 derivations based on the gordon 1962 model describe it as determined by return on equity beaver and morse 1978 show that this ratio indicates transitory earnings the molodovsky effect from molodovsky 1953 it has also been interpreted as an indicator of mispriced stocks basu 1977 and jaffee keim and westerfield 1989 and as a product of accounting principles craig johnson and joy 1987 the p b ratio received less academic attention until fama and french 1992 traditionally it was interpreted as indicating expected return on equity see for example graham dodd and cottle 1962 this interpretation is given expression in the standard formula reconciling price to book value in preinreich 1938 edwards and bell 1961 and peasnell 1982 for example like pie p b has been modeled as a growth

the changing role of government in financing health care an international perspective this paper explores the changing role of government involvement in health care financing policy outside the united states it provides a review of the economics literature in this area to elucidate the implications of recent policy changes on efficiency costs and quality our review reveals that there has been some convergence in policies adopted across countries to improve financing incentives and encourage efficient use of health services in the case of risk pooling all countries with competing pools experience similar difficulties with selection and are adopting more sophisticated forms of risk adjustment in the case of hospital competition the key drivers of success appear to be what is competed on and measurable rather than whether the system is public or private in the case of both the success of performance related pay for providers and issues resulting from wait times evidence differs within and across jurisdictions however the evidence does suggest that some governments have effectively reduced wait times when they have chosen explicitly to focus on achieving this goal many countries are exploring new ways of generating revenues for health care to enable them to cope with significant cost growth but there is little evidence to suggest that collection mechanisms alone are effective in managing the cost or quality of care jel h51 i11 i18

the effects of drug subsidies on out of pocket prescription drug expenditures by seniors regional evidence from canada abstract between 1970 and 1986 all canadian provinces introduced some version of a prescription drug subsidy for those aged 65 years or over and since 1986 all the provinces have increased copayments or deductibles to some degree employing a first order approximation to the welfare gains from a subsidy we find evidence that these subsidies have been less redistributive than an absolute per household cash transfer but slightly more redistributive than a transfer that would increase each household s income by the same percentage such evidence may have relevance for predicting the redistributive effects of a potential national prescription drug plan for seniors in the us

social security reform and investment in education is there scope for a pareto improvement we propose a pareto improving policy which reduces the overall wage tax burden in an economy with intergenerational trade in a fixed factor of production here labelled as land we analyse a second best environment in which the government cannot resort to non distortionary land taxes reducing the social security contribution rate encourages investment in human capital future efficiency gains accruing to complementary land are capitalized in its value the capital gains may compensate land owning pensioners for reduced benefits we also explain why the unfunded pension system may have lost its appeal even for pensioners after its introduction

efficiency enhancing signalling in the samaritan s dilemma suppose an altruistic person a is willing to transfer resources to a second person b if b comes upon hard times if b anticipates that a will act in this manner b will save too little from both agents point of view this is the samaritan s dilemma this paper shows that the undersaving result is mitigated if we relax the standard assumption of complete information because if a is uncertain about how big b s need for support is b will have an incentive to signal that he is in great need by saving more than he otherwise would have done

the rewards to meeting or beating earnings expectations abstract this paper finds that firms that meet or beat current analysts earnings expectations mbe enjoy a higher return over the quarter than firms with similar quarterly earnings forecast errors that fail to meet these expectations further such a premium to mbe although somewhat smaller exists in the cases where mbe is likely to have been achieved through earnings or expectations management the findings also indicate that the premium to mbe is a leading indicator of future performance this premium and its predictive ability are only marginally affected by whether the mbe is genuine or the result of earnings or expectations management

empirical research on accounting choice abstract we review research from the 1990s that examines the determinants and consequences of accounting choice structuring our analysis around the three types of market imperfections that influence managers choices agency costs information asymmetries and externalities affecting non contracting parties we conclude that research in the 1990s made limited progress in expanding our understanding of accounting choice because of limitations in research design and a focus on replication rather than extension of current knowledge we discuss opportunities for future research recommending the exploration of the economic implications of accounting choice by addressing the three different reasons why accounting matters

bounded rationality expectations and child labour this paper develops a model with overlapping generations where the household s optimal fertility child labour and education decisions depend on the parents expectations or beliefs about the return to education it is shown that there exists a range of parental income where the fertility rate is high and children participate in the labour market and receive an incomplete education if a parent believes the return to education is low the act of participating in the labour market reduces the child s ability to accumulate human capital thus the action of sending a child into the labour market is sufficient to ensure that the parents initially pessimistic expectations are fulfilled it is then shown that a one time policy intervention such as banning child labour and mandatory education can be enough to move a country from the positive child labour equilibrium to an equilibrium with no child labour rationalite limitee anticipations et travail des enfants ce memoire developpe un modele de chevauchement des generations ou la fecondite optimale du menage le travail des enfants et les decisions a propos de l education dependent des anticipations des parents ou de qu ils croient etre le rendement sur l education on montre qu il existe un eventail de revenus des parents pour lequel le taux de fecondite est eleve et les enfants participent au marche du travail et recoivent une education incomplete si un parent croit que le rendement sur l investissement en education est faible le fait d entrer sur le marche du travail reduit la capacite de l enfant a accumuler du capital humain et donc le fait de l envoyer sur le marche du travail est suffisant pour s assurer que les anticipations pessimistes du parent se realisent on montre qu une intervention ponctuelle de politique publique a un moment donne comme bannir le travail des enfants ou imposer l education obligatoire peut suffire pour deplacer un pays d un equilibre avec travail des enfants vers un equilibre sans travail des enfants

gdp management to meet or beat growth targets abstract we apply the discontinuity methodology from the accounting literature to a political economy setting of gdp reporting and examine whether chinese local governments manage regional gdp numbers we find strong evidence of discontinuities around zero in the distribution of actual minus target gdp growth rates the frequencies of just meeting or beating gdp growth targets are about five four times the frequencies of just missing targets at the prefecture province level the results are stronger for governors with longer tenures and those without political connections to higher level officials as well as for local governments with more resources under their control

social security the family and economic growth we show that a defined benefits payg social security system distorts key family based choices that affect economic growth we identify human capital as the engine of growth and the motivating forces linking the family s overlapping generations as mutually productive intergenerational transfers and or altruism the payg system is shown to affect adversely at least one of three determinants of the economy s growth path fertility savings and investment in human capital the specific effects may vary over different stages of economic development the growth rate is expected to fall in advanced economies our analysis indicates that the effect may be sizeable jel 915 111 850

nonparametric regression techniques in economics this introduction to nonparametric regression emphasizes techniques that might be most accessible and useful to the applied economist the paper begins with a brief overview of the class of models under study and central theoretical issues such as the curse of dimensionality the bias variance trade off and rates of convergence the paper then focuses on kernel and nonparametric least squares estimation of the nonparametric regression model and optimal differencing estimation of the partial linear model constrained estimation and hypothesis testing is also discussed empirical examples include returns to scale in electricity distribution and hedonic pricing of housing attributes

dynamic allocation in an altruistic overlapping generations economy abstract this paper is concerned with the issue does there exist a social security program which can be maintained period after period to address this issue the paper considers dynamic allocation in an altruistic overlapping generations economy the altruism is intergenerational nonpaternalistic and two sided it is assumed that generations coexisting in the same period agree on a social welfare function which evaluates the consumption of various generations and play a game against those living in different periods a perfect equilibrium of this game is shown to exist and its properties are examined journal of economic literature classification numbers c72 d62 h55

on the time consistency of the government s social security benefit policy abstract it is shown that the government s social security benefit policy may be time inconsistent when a worker s future benefit depends on his labor earnings history when the future benefit is tied to current labor supply the benefit will distort the worker s labor supply decision ex ante of retirement but not ex post any excess burden associated with the government s benefit policy is taken into account in the open loop policy game but is ignored in the closed loop game this will generally imply that the benefit will be larger under the closed loop rule ceteris paribus

lessons for an aging society the political sustainability of social security systems what is the future of social systems in oecd countries in our view the answer belongs to the realm of politics we evaluate how political constraints shape the social security system in six countries france germany italy spain the uk and the us under population aging two main aspects of the aging process are relevant to the analysis first the increase in the dependency ratio the ratio of retirees of workers reduces the average profitability of the unfunded social security system thereby inducing the agents to reduce the size of the system by substituting their claims towards future pensions with more private savings second an aging electorate leads to larger systems since it increases the relevance of pension spending on the policy makers agenda the overall assessment from our simulations is that the political aspect dominates in all countries albeit with some differences spain the fastest aging country faces the largest increase in the social security contribution rate when labor market considerations are introduced the political effect still dominates but it is less sizeable country specific characteristics not accounted for in our simulations such as the degree of redistribution in the pension system and the existence of family ties in the society may also matter our simulations deliver a strong policy implication an increase in the effective retirement age always decreases the size of the system chosen by the voters while often increasing its generosity finally delegation of pension policy to the ec may reduce political accountability and hence help to reform the systems

intergenerational altruism with future bias abstract we show that standard preferences of altruistic overlapping generations exhibit future bias which involves preference reversals associated with increasing impatience this underlies a conflict of interest between successive generations we explore the implications of this conflict for intergenerational redistribution when there is a sequence of utilitarian governments representing living generations and choosing policies independently over time we argue that future bias creates incentives to legislate and sustain a pay as you go pension system which every government views as a self enforcing commitment mechanism to increase future old age transfers

the future of social security we analyze the effect of the projected demographic transition on the political support for social security and equilibrium outcomes embedding a probabilistic voting setup of electoral competition in the standard olg model with capital accumulation we find that intergenerational transfers arise in the absence of altruism commitment or trigger strategies closed form solutions predict population ageing to lead to higher social security tax rates a rising share of pensions in gdp but eventually lower social security benefits per retiree the response of equilibrium tax rates to demographic shocks reduces old age consumption risk calibrated to match features of the u s economy the model suggests that in response to the projected demographic transition social security tax rates will gradually increase to 16 other policies that distort labor supply will become less important labor supply therefore will rise in contrast with frequently voiced fears

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

asymmetric timeliness of earnings market to book and conservatism in financial reporting abstract using an accounting conservatism theory that reflects accounting s role in practice we investigate the relation between two extensively used measures of conservatism asymmetric timeliness of earnings and the market to book ratio mtb we predict and observe that when asymmetric timeliness is measured cumulatively over long periods its relation with end of period mtb is positive when asymmetric timeliness is measured over short periods its dependence on beginning of period composition of equity value ev is responsible for its negative association with mtb further asymmetric timeliness appears to measure conservatism more efficiently when it is estimated cumulatively over multiple periods

social security and endogenous growth abstract this paper examines the effects of social security on the steady state growth of per capita income in an endogenous growth model in which agents care about their own consumption the number of children and the welfare of each child it shows that an unfunded program may simulate growth by reducing fertility and increasing the ratio of human capital investment per child to per family income when bequests are positive also it may cause faster growth than funded programs especially when receipts from funded programs are independent of contributions when voluntary saving is positive funded social security is neutral if receipts are linked to contributions and most likely depresses growth if receipts are independent of contributions

public economics and the theory of public policy when james mirrlees and william vickrey were awarded the nobel prize in economics last year it marked only the third time that the award had gone to scholars of public sector economics in contrast to the reception given to the previous two winners ronald coase and james buchanan the news was greeted with some bewilderment by policy specialists once removed from the academic literature who are mirrlees and vickrey and what have they done that has been of lasting benefit to the study of public economics let alone of practical benefit to policy makers this seems to me to be a fair question coase after all had set out a conceptual approach to the study of externalities and transaction costs that has become an implicit part of the methodological baggage carried around by policy economists and policy makers alike buchanan was in part responsible for the welcome emphasis on institutions in public sector decision making and for insisting that politicians bureaucrats and voters are human beings with human motives the legacy of mirrlees and vickrey is less well known but i would argue it is every bit as profound their approach to the theory of economic policy which is grounded on the importance of imperfect information as a constraint on public policy has changed the very nature of public economics research and of its implications for economic

public pensions as optimal social contracts abstract a simple overlapping generations model is modified to allow for an externality experienced by the young from consumption by the elderly this sets up a game between generations in which one generation s strategy may be to save too little and rely on gifts from the young e g public assistance for retirement income social security can therefore be viewed as a pareto optimal contract to restore efficient intertemporal allocation a funded public pension plan corresponds to forced saving but is vulnerable in that the next young generation may stop contributing rely on its children for retirement assistance and meanwhile reap the consumption externality from the current elderly s social security benefits this suggests a forced giving or pay as you go type of compulsory pension plan such as exists in most nations which also has the advantage of aiding the initial old generation and therefore generating an immediate consumption externality for the initial young the approach can also be used to explain other aspects of existing social security

pay as you go public pensions with endogenous fertility abstract veall s 1986 model of public pensions is generalized to allow for endogenous fertility we show that gifts to the old which can be viewed as social security contributions are always positive in the steady state an optimal stationary allocation is sustainable if savings are zero and fertility is exogenous however the optimal allocation is in general not sustainable in particular if a government enforces a social security plan setting the pension level at the optimal gifts and individuals optimize under the pension constraint the resulting sustainable outcome is in general different from either the optimal or nash outcome

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

forward and backward intergenerational goods why is social security good for the environment this paper studies the ability of nonmarket institutions to invest optimally in forward intergenerational goods figs such as education and the environment when agents are selfish or exhibit paternalistic altruism we show that backward intergenerational goods bigs such as social security play a crucial role in sustaining investment in figs without them investment is inefficiently low but with them optimal investment is possible we also show that making the provision of bigs mandatory crowds out the voluntary provision of figs and that population aging can increase investment in figs

antisocial security the puzzle of beggar thy children policies the u s social security program has irrevocably transferred substantial wealth from workers to their ostensibly altruistic parents after some alternative explanations for this paradox are addressed a formal model is developed to show that a majority of rational voters who care about their descendants can support the preservation of current benefits for themselves but accept the prospect of social security s future retrenchment incorporating elements of tabellini s 2000 positive theory of social security and benabou and ok s 2001 analysis of income mobility the model identifies specific forces affecting this time varying individual support for social security these forces are embodied in three hypotheses related to income mobility relative income level and age an ordered logit analysis of cumulative anes data supports these hypotheses

constraints in perfect foresight models the case of old age savings and public pensions abstract the solution of discrete time perfect foresight models with constrained state variables differs considerably from the solution of models without constraints in this paper this is worked out for a simple model of decision making on public pensions

private insurance subsidies and public health care markets evidence from canada in this study i examine the effects of government subsidies to employer provided health insurance on the decision to purchase insurance and on utilization of publicly funded health services using unique variation in tax subsidies across canadian provinces as an instrument i estimate the effects of these subsidies on the demand for supplemental health insurance and their extended effects on the decision to use publicly funded health services my results show that government subsidies through tax exemptions have significant effects on the decision to purchase insurance furthermore additional insurance policies lead to moral hazard in the use of publicly funded health services jel classification h2 h4 11

association between accounting performance measures and stock prices a test of the life cycle hypothesis abstract this paper posits that stock market response to two accounting performance measures sales growth and capital investment is a function of firm life cycle stage firms are grouped into various life cycle portfolios using dividend payout sales growth and age as predicted the empirical results indicate a monotonic decline in the response coefficients of unexpected sales growth and unexpected capital investment from the growth to the stagnant stages additional analysis suggests that this relation is not driven by a firm size effect risk differences or measurement error in the proxies for performance measures

biases and lags in book value and their effects on the ability of the book to market ratio to predict book return on equity in this paper we distinguish two sources of variation in the book to market ratio bias and lags in book value hereafter bias and lags with different implications for the book to market ratio s ability to predict future book return on equity specifically we hypothesize and find that the bias component of the book to market ratio has a more persistent cross sectional association with future book return on equity than does the lag component this investigation is motivated both by the central role of expectations of book return on equity in the discounted residual in come valuation model e g see feltham and ohlson 1995 and by prior empirical research that finds that the book to market ratio is correlated with future book return on equity e g see fama and french 1992 1995 penman 1992 and bernard 1994

the relation between religiosity and private bank outcomes abstract we examine the effect of headquarters local religiosity on private bank outcomes religiosity is associated with lower risk taking for public banks but the unique features of private banks may result in a different effect for private banks we find religiosity is associated with greater asset risk taking at the same time however religiosity is negatively associated with solvency risk and return on asset roa volatility and is associated with higher roas and fewer failures we reconcile these results by finding banks in areas with higher religiosity recognize larger fees from providing additional banking services likely due to relationships formed from more risky lending as a result these banks are more less likely to realize extreme positive negative performance we also find religiosity is associated with lower earnings management and increased conservatism collectively our results confirm private banks are unique and religiosity can have a significant and nuanced effect on bank outcomes

social security as trade among living generations we model u s social security that is legislated endogeneously by living generations specifically we consider the effects of social security on resource allocation and pareto optimality examining which generations gain from social security and whether some generations lose because saving and transfer decisions are made sequentially in the real world we use an infinite horizon overlapping generations framework in which life cycle saving and transfers to the old are determined by living agents we focus on the case in which agents are altruistic but place sufficiently greater weight on own comsumption than on the consumption of agents in other generations so that starting from a steady state without social security living agents would gain utility if consumption were shifted marginally to them from later generations excerpt

government debt in an overlapping generations model with bequests and gifts in 1974 robert barro argued that if individuals in successive generations were linked by bequests changes in the stock of government debt or in social security programs would have no effect on the steady state capital stock barro assumed that individuals held static expectations and that the size of the population was constant martin feldstein 1974 1977 had concluded that social security would reduce the capital labor ratio in models that did not admit a bequest motive and in his 1976 comment on barro argued that the introduction of government debt or social security into a perfect foresight dynamic growth model with bequests would still reduce the capital labor ratio barro replied that feldstein s criticisms were invalid if the steady state capital labor ratio were smaller than the golden rule level but would be correct if the opposite were true barro did suggest however that the latter possibility with overaccumulation of capital might be ruled out in his model as it was in miguel sidrauski 1967 but he was unable to demonstrate that the required behavior would be consistent with utility maximization by finite lived individuals 1976 p 345 although recent work by willem buiter 1979 jeffrey carmichael 1979 1982 truman bewley 1981 a b and others has helped to elucidate the nature of overlapping generations models with bequests and gifts and the issues in the barro feldstein debate they remain far from clear the purpose of this paper is to shed a little more light on the subject in what follows i contend that some of the authors cited above either have specified the individual s optimization problem in an asymmetric way or have failed to impose necessary conditions for a sensible optimization problem or both there is a natural specification of the barro model 1 that emphasizes the similarity between this model and optimal growth models see for example david cass 1965 peter diamond 1973 here in steady state equilibrium the aftertax interest rate r must equal the rate at which individuals discount the utility of their heirs p r p has become known as the modified golden rule and a meaningful individual optimization problem requires that p exceed n the natural growth rate of the economy my results confirm barro s hunch about his model in a barro model r must exceed n much of the barro feldstein 1976 interchange which assumed that r could have any relation to n is wrong headed barro and feldstein reach different conclusions about the effects of government debt and social security because they assume different individual utility functions also my results contrast sharply with those of buiter and carmichael for example carmichael concluded that with intergenerational transfers from parents to children bequests r must exceed n but with transfers in the opposite direction n must exceed r 1982 pp 205 06 indeed i believe that the buiter carmichael representation of the barro model is logically faulty see section ii in section i i outline an overlapping generations model with gifts and bequests and derive its steady state properties in the next section i discuss the shortand long run effects of introducing government debt into the model and contrast my results with those

have financial statements lost their relevance the authors explore the concern that financial statements no longer have the same relevance to investors that they had in the past they test for value relevance by measuring the total return that could have been earned from prior knowledge of financial statement information and by examining the explanatory power of accounting information on market values and annual market adjusted returns both analyses are applied to a broad sample of exchange listed and nasdaq firms for the 1952 94 period the authors find mixed evidence on value relevance of financial statement reporting during the test period

nonparametric estimation of exact consumers surplus and deadweight loss we apply nonparametric regression models to estimation of demand curves of the type most often used in applied research from the demand curve estimators we derive estimates of exact consumers surplus and deadweight loss which are the most widely used welfare and economic efficiency measures in areas of economics such as public finance we also develop tests of the symmetry and downward sloping properties of compensated demand we work out asymptotic normal sampling theory for kernel and series nonparametric estimators as well as for the parametric case the paper includes an application to gasoline demand empirical questions of interest here are the shape of the demand curve and the average magnitude of welfare loss from a tax on gasoline in this application we compare parametric and nonparametric estimates of the demand curve calculate exact and approximate measures of consumers surplus and deadweight loss and give standard error estimates we also analyze the sensitivity of the welfare measures to components of nonparametric regression estimators such as the number of terms in a series approximation

a positive theory of social security in many countries social security accounts for a large fraction of the government budget why is this so given that at any point in time the number of recipients of social security benefits is smaller than the number of contributors in the overlapping generations model studied in this paper all individuals currently alive vote on social security in every period in equilibrium the size of social security is larger the greater is the proportion of elderly people in the population and the greater is the inequality of pre tax income within each generation both predictions of the theory are supported by the empirical evidence in cross country data
