on measures of excess burden and their application abstract new measures of the additional excess burden of a tax reform are proposed and are shown to be useful in three key policy applications these new measures induce a unique measure of marginal excess burden meb among its interesting properties meb is uniformly zero for a proportional tax on inelastically supplied labor problems in applying the standard measures of total excess burden are demonstrated it is concluded that the induced measure of the marginal cost of funds mcf should be regarded as the most useful concept in applied tax analysis

an equilibrium model of incentive contracts in the presence of information manipulation abstract this paper develops an agency model in which stock based compensation is a double edged sword inducing managers to exert productive effort but also to divert valuable firm resources to misrepresent performance we examine how the potential for manipulation affects the equilibrium level of pay for performance sensitivity and derive several new cross sectional implications that are consistent with recent empirical studies in addition we analyze the impact of recent regulatory changes contained in the sarbanes oxley act of 2002 and show how policies intended to increase firm value by reducing misrepresentation can actually reduce firm value or increase the upward bias in manipulated disclosures

environmental tax on products and services based on their carbon footprint a case study of the pulp and paper sector the main aim of this work is to define an environmental tax on products based on their carbon footprint we examine the relevance of life cycle analysis lca and environmentally extended input output analysis eio as methodological tools for identifying the emission intensities on which the tax is based the price effects of the tax and the policy implications of considering non co2 greenhouse gases ghg are also analyzed the results from the case study on pulp production show that the environmental tax rate based on lca 1 8 is higher than both eio approaches 0 8 and 1 4 for product and industry respectively but they are of the same order of magnitude although lca is more product specific and provides a more detailed analysis we recommend eio as a more relevant approach to applying an economy wide environmental tax if an environmental tax were applied to non co2 ghg instead to co2 alone the tax would greatly affects sectors such as agriculture mining of coal extraction of peat and food therefore it is worthwhile for policy makers to pay attention to the implications of considering either a co2 tax or a global ghg emissions tax in order to make their policy measures effective and meaningful

incentives discretion and asset valuation in closed end mutual funds this paper studies earnings management using 363 closed end mutual fund firm years of data closed end fund assets consist of unrestricted and restricted securities and realized and unrealized income while unrestricted securities are not subject to earnings management restricted security values are largely discretionary managerial valuation of restricted securities is modeled as contingent on unrestricted returns relative to a performance benchmark four unrestricted performance regions are identified known multi period compensation incentives become the basis for hypothesizing earnings management behaviors in the regions in the form of restricted security valuation across several benchmarks the results are consistent with multi period maximization rather than simpler single period compensation maximization or income smoothing funds with extreme unrestricted performance show relatively larger income decreasing earnings management and funds with slightly below benchmark returns show relatively larger income increasing earnings management than those slightly above these results clarify the relationship between complex earnings management behavior and managerial incentives

political cost incentives for earnings management in the cable television industry abstract this study tests political costs theory by examining the cable television industry during periods of congressional scrutiny earnings management is measured using discretionary accruals and data are consistent with managerial incentives to mitigate the effects of political scrutiny and potential industry reregulation tests are also done using within sample comparisons of firms firms for which proposed regulations are expected to be more harmful have greater income decreasing accruals and for some tests firms for which cable television operations are more important have greater income decreasing accruals test results are robust to the inclusion of control variables for firm performance and size

value added taxation in the ec after 1992 abstract this paper examines the quantitative effects of the transitional system of value added taxation for intra ec trade between 1993 and 1997 as recently adopted by the ecofin council first the administration of the current destination principle and the interim solution are described a short representation of the empirical general equilibrium model featuring seven ec regions and 14 production sectors follows finally the effects of a switch to the transitional system are evaluated by using numerical simulations the adopted provisions with regard to cross frontier sales to final consumers open tax arbitrage possibilities which favour low tax countries at the cost of their ec partners when decomposing welfare effects international tax revenue shifts prove to dominate while substitution effects have relatively little influence on economic welfare

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

environmental taxation and unemployment some evidence on the double dividend hypothesis in europe abstract the employment double dividend hypothesis suggests that an appropriately designed fiscal reform in which emission charges are used to subsidize employers social security contributions may realize at least two relevant policy goals a better quality of the environment and at the same time an increase in employment levels this paper uses a newly developed econometric general equilibrium model for the european union as well as for each member country and presents simulation results up to the year 2010 of the effects of a european carbon tax the revenues from which are recycled to reduce employers social security contributions the results show that recycling carbon tax revenues may provide an employment double dividend only in the short run

carbon tax simulations using a household demand model abstract the main objective of this paper is to analyse consumer response and welfare effects due to changes in energy or environmental policy to achieve this objective we formulate and estimate an econometric model for non durable consumer demand in sweden that utilises micro and macro data in the simulations we consider two revenue neutral scenarios that both imply a doubling of the co2 tax one that returns the revenues in the form of a lower vat and one that subsidise public transport one conclusion from the simulations is that the co2 tax has regional distribution effects in the sense that household living in sparsely populated areas carry a larger share of the tax burden

factors associated with the year end decline in working capital working capital is an important indicator of firm operational efficiency all else being equal lower levels signal greater efficiency managers are thus likely to be motivated to report lower levels of working capital at times of greater external attention we find that working capital levels decrease in the fourth fiscal quarter significantly more than expected conditional on seasonal changes in economic activity the decrease subsequently reverses in the following first fiscal quarter evidence indicates that firms manage down year end working capital through transactions that increase year end operating cash flow and that firms spread this activity over all working capital accounts finally the temporary decrease in year end working capital is correlated with compensation benchmarks and analysts annual cash flow forecasts the temporary drop is also more pronounced for firms with industry dominance this paper was accepted by mary barth accounting

intermediate goods and the incidence of the corporation income tax abstract intermediate goods are introduced into a general equilibrium model of the incidence of the corporation income tax several theoretical conclusions about the role of such goods are established many well known propositions about the incidence of the corporation income tax emanating from models with only final goods need to be modified estimates from u s data suggest that if intermediate goods are left out results will be misleading especially if these goods are a relatively large sector in the economy and possibilities of substituting capital for labor in their production and of substituting them for other productive factors in the final good industries are rather limited

the relation between earnings based measures in firm debt contracts and ceo pay sensitivity to earnings abstract i investigate how implicit incentives provided by earnings based debt covenants affect the structure of ceo compensation contracts this provides a new and unique view of how the ceo s incentives are shaped by not only his compensation contract but also debt contracts i find when debt contracts contain an earnings based covenant the ceo s pay sensitivity to earnings is muted additionally i find some evidence that pay sensitivity to earnings varies with earnings based covenant slack this study provides evidence consistent with shareholders rebalancing the ceo s earnings incentives in the presence of earnings based covenants thereby tilting incentives away from earnings performance

effect of derivative accounting rules on corporate risk management behavior abstract i examine the effect of the accounting standard for derivative instruments sfas no 133 on corporate risk management behavior i classify a derivative user as an effective hedger eh firm if its risk exposures decreased after the initiation of the derivatives program and as an ineffective hedger speculator is firm otherwise i find that volatility of cash flows and risk exposures related to interest rate foreign exchange rate and commodity price decrease significantly for is firms but not for eh firms suggesting that is firms engaged in more prudent risk management activities after the adoption of sfas no 133

bonus pools and the informativeness principle abstract previous work on moral hazard problems has shown that under certain conditions bonus contracts create optimal individual incentives for risk neutral workers in our paper we demonstrate that if a firm employs at least two workers it may further benefit from combining worker compensation via a bonus pool contract and relative performance evaluation such combination leads to saved rents under a wide class of luck distributions in addition if the employer is wealth constrained complementing individual bonus contracts by the possibility of pooling bonuses can increase the set of implementable effort levels all our results hold even though workers outputs are technically and stochastically independent so that in view of holmstrom s informativeness principle individual bonus contracts would be expected to dominate bonus pool contracts

tax incidence in a hierarchical model abstract production hierarchies are common in input output tables but have not been used much in analytical work on tax incidence a general equilibrium model with two mobile factors and flexible production coefficients is set up for this purpose earlier studies generally assumed one factor and fixed coefficients there is one intermediate good a final good and one with both final and intermediate uses some features of existing models with intermediate and final goods carry over to hierarchical technology but results about incidence of factor and commodity taxes differ markedly even under severe restrictions on elasticities of substitution and other parameters

nonlinear dynamics in discretionary accruals an analysis of bank loan loss provisions abstract several studies have analyzed discretionary accruals to address earnings smoothing behaviors in the banking industry we argue that the characteristic link between accruals and earnings may be nonlinear since both the incentives to manipulate income and the practical way to do so depend partially on the relative size of earnings given a sample of 15 268 us banks over the period 1996 2011 the main results in this paper suggest that depending on the size of earnings bank managers tend to engage in earnings decreasing strategies when earnings are negative big bath use earnings increasing strategies when earnings are positive and use provisions as a smoothing device when earnings are positive and substantial cookie jar accounting this evidence which cannot be explained by the earnings smoothing hypothesis is consistent with the compensation theory neglecting nonlinear patterns in the econometric modeling of these accruals may lead to misleading conclusions regarding the characteristic strategies used in earnings management

empirical tests of budget ratcheting and its effect on managers discretionary accrual choices abstract in this paper we investigate whether budgets ratchet using business unit data from a large multinational corporation we find evidence consistent with ratcheting where favorable budget variances result in performance budget increases that are larger than decreases associated with unfavorable variances of the same magnitude we argue that under ratcheting the cost of reporting positive transitory earnings surprises outweigh the short term benefits of the current period bonus consequently we hypothesize that managers make income decreasing discretionary accruals to offset transitory earnings surprises beyond the level expected under fixed budgets using a proxy for transitory earnings surprise we find evidence consistent with this hypothesis

substitutes or complements a configurational examination of corporate governance mechanisms we conduct an exploratory qualitative comparative case analysis of the s p 1500 firms with the aim of elaborating theory on how corporate governance mechanisms work together effectively to do so we integrate extant theory and research to specify the bundle of mechanisms that operate to mitigate the agency problem among publicly traded corporations and review what previous research has said about how these mechanisms combine we then use the fuzzy set approach to qualitative comparitive analysis qca to explore the combinations of governance mechanisms that exist among the s p 1500 firms that achieve high and not high profitability our findings suggest that high profits result when ceo incentive alignment and monitoring mechanisms work together as complements rather than as substitutes furthermore they show that high profits are obtained when both internal and external monitoring mechanisms are present at the same time however monitoring mechanisms evidently combine in complex ways such that the

on reforming the welfare system abstract using a simulation model for a small open economy quebec 1986 various negative income tax nit and workfare schemes are compared from the point of view of efficiency and equity the main finding is that there exist workfare schemes that are superior both to the quebec regime of 1986 and to a nit characterized by a 100 percent implicit tax rate however these workfare schemes are dominated by some nit programs this suggests that it may be necessary to have work requirements that vary across socio demographic classes for a workfare plan to be superior to any nit combining workfare with an nit could also be the prescription

the asymmetric relationship between executive earnings management and compensation a panel threshold regression approach abstractprior research shows that chief executive officers ceos are rewarded for their earnings management we re examine this issue using a panel threshold regression approach which allows the effect of earnings management on the ceo compensation to change across the level of earnings management and ceo compensation our results show that the effect of ceos discretionary accounting choices on their compensation is not homogeneous across various degrees of earnings management and compensation in particular for firms with moderate inordinate levels of earnings management and ceo compensation earnings management is rewarded penalized

labour supply tax evasion and the marginal cost of public funds an empirical investigation abstract in this paper we extend the concept of marginal cost of public funds itmcf to incorporate tax evasion in the labour market mcf values are also computed from various tax reforms applied to the province of quebec canada 1985 for this purpose a utility based labour supply model that allows for both regular and irregular work activities is used at the benchmark situation the mcf associated with an increase in marginal income tax rates ranges between 1 39 and 1 53 depending upon whether we consider rationing or not moreover the presence of the irregular sector accounts for between 0 02 and 0 05 of this mcf although small in magnitude the impact of the irregular sector increases rapidly with the level of marginal tax rates

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

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

on the marginal welfare cost of taxation this paper develops a rigorous partial equilibrium analysis of the determinants of margin al welfare cost mwc of taxes on labor earnings it shows that four key parameters interact to determine the magnitude of mwc using aggregate data and plausible ranges of values for the parameters mwc can vary from under 10 percent to more than 300 percent of marginal tax revenue intermediate parameter values sugge st mwc is in the 25 50 percent range however the more extreme estimates cannot be ruled out on the basis of available evidence suggesting that mwc cannot yet be copyright 1987 by american economic association

compensating variation consumer s surplus and welfare the compensating variation was defined by j r hicks 1942 as the amount one would have to deduct from a person s income to make him just as well off after a change in prices and income as he had been in the initial situation if the compensating variation is positive the individual is better off under the new situation since the compensating variation furnishes a uniquely defined numerical cardinal indicator of welfare improvement it provides an implicit ranking of alternative prospective situations not only relative to the initial situation but also relative to each other in practice this appears to be how this and other tools of cost benefit analysis are actually used one is interested in knowing not only whether a particular bridge or a particular excise tax will lead to an improvement in welfare but which out of a set of alternative bridges or alternative tax systems will improve welfare the most 1 in this paper we analyze conditions under which the compensating variation can be validly used in this generalized sense these turn out to be precisely the same as conditions previously derived see our 1976 paper for the valid use of consumer s surplus as a welfare measure in our final section we analyze the problem of deriving the generalized equivalent and compensating variations either exactly or approximately from observable demand functions by means of generalizations of or alternatives to consumer s surplus

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

another note on deadweight loss abstract in a recent article j a kay proposed a useful measure of the deadweight loss arising from a commodity tax system the measure answers the question how much more would the taxed consumer be willing to pay in a lump sum rather than as a commodity tax kay s computation of the marginal deadweight loss does not yield the change in this measure for small changes in commodity tax rates however this note clarifies kay s otherwise excellent contribution derives the measure for cobb douglas utilities and examines a useful property of it

carbon tax incidence on household demand effects on welfare income inequality and poverty incidence in thailand abstract studying the impact of a carbon tax on household demand can be relevant in terms of securing public acceptance of a carbon tax and clarifying the implications for policy design this paper aims to fill a gap in the academic literature by simulating carbon tax scenarios and estimating distributional effects of the tax on household welfare income inequality and poverty rates based on household consumption in thailand the study employs a microsimulation model incorporating the economy wide effects of the tax on prices and consumers behavioral responses to changes in prices the results indicate that a carbon tax is progressive in thailand under revenue recycling scenarios by expanding social transfer programs when carbon tax revenues are recycled through pensions for elderly people the carbon tax could reduce the poverty rate and improve the welfare of households in the lowest quintile the results imply that the distributional impacts of environmental taxes could result in favorable outcomes for income inequality and poverty reduction in developing countries

the theory of reform and indian indirect taxes abstract given a set of value judgements an initial state and a model of the economy one can ask whether some feasible tax change would increase welfare we do this by defining the marginal cost in terms of welfare of raising an extra rupee from the i th good the inverse optimum problem is the calculation of non negative welfare weights on households which imply that the initial state is optimum if no such welfare weights exist then a pareto improvement is possible we illustrate the concepts and results using data from the indian economy for 1979 1980 directions of tax reform for a number of specific social welfare functions and for pareto improvements are presented

managing interacting accounting measures to meet multiple objectives a study of lifo firms abstract using a sample of lifo users we examine the strengths and weaknesses of adopting a simultaneous equations approach to study managers adjustments of interacting accounting measures that meet multiple objectives we focus on the importance of considering differences in the costs and the effectiveness of adjusting accounting measures in addition we examine managers objectives in subsequent years and how adjustments reversals affect those objectives although generally consistent with earlier studies of lifo inventory adjustments our results indicate that modelling interacting accounting measures such as other current accruals and depreciation leads to differing conclusions about the role of taxes

annual bonus schemes and the manipulation of earnings abstract using confidential data of executive specific short term bonus plans we investigate the extent to which executives manipulate earnings to maximize the present value of bonus plan payments as such this paper extends the work of healy 1985 like healy we find evidence consistent with the hypothesis that managers manipulate earnings downwards when their bonuses are at their maximum unlike healy we find no evidence that managers manipulate earnings downwards when earnings are below the minimum necessary to receive any bonus we demonstrate that healy s results at the lower bound are likely to be induced by his methodology

simulation of indirect tax reforms using pooled micro and macro french data this paper assesses the consequences of two reforms of the french indirect taxation system a vat harmonization which is close to initial ec proposals and a carbon tax which aims at decreasing the emissions of carbon dioxide we simulate the effects of tax reforms using estimates of a model of household expenditure behaviour estimation is obtained by using the property of perfect aggregation over households of the almost ideal demand system on pooled micro data from the 1978 1979 1984 1985 1989 issues of the french enquete budgets des familles combined with macro data from the quarterly national accounts from 1970 to 1990 simulations are conducted using a subsample of households from the 1989 consumer survey and generate useful results about the behavioural reactions to tax changes the impact on government revenue and the distributional effects of the reforms

exemption versus zero rating a hidden problem of vat abstract we examine the difference between exemptions and zero rating under a consumption based vat in a numerical general equilibrium model to allow for a better understanding of the accruing efficiency effects we first develop a method to convert the nominal vat rates into effective tax rates on categories of final demand then we show how these effective tax rates can be used to perform a gradual transition from exemption to zero rating

environmental and public finance aspects of the taxation of energy this paper reviews potential applications of environmental taxes in the energy sector theoretical and practical arguments for using environmental taxes are reviewed and possible arrangements outlined for levying environmental taxes on energy in contrast to most environmental taxes taxes on energy have the potential to raise revenues sufficient to alter the constraints and opportunities in fiscal policy a carbon tax levied at a rate of 200 pounds per tonne could raise revenues equivalent to about 11 per cent of total uk tax receipts allowing income tax to be halved or corporation tax abolished inappropriate use of the revenues or their unnecessary dissipation can greatly add to the costs of environmental policy but environmental taxes are unlikely reduce the overall excess burden from taxation below the current level and the case for ecotaxes must thus primarily be made in terms of their environmental benefits copyright 1998 by oxford university press

parametric equivalence scales and scale relativities we respond to banks and johnson s 1994 comment on coulter et al 1992 drawing on a more general discussion of parametric equivalence scale and scale relativity issues and new empirical results we show that criticisms of our earlier work are unfounded when the mcclements scale is properly characterised the scale does indeed provide lower estimates of poverty and inequality levels than most other scales we reiterate our conclusion that relationships between scale relativities and inequality and poverty indices may be index specific moreover the picture about distributional trends may differ from that about levels

an explanation for accounting income smoothing it is widely believed that corporate managers often engage in income smoothing taking actions to dampen fluctuations in their firms publicly reported net income one reason given for this is that managers think that investors pay more for a firm with a smoother income stream see ronen and sadan 1981 while there have been many empirical studies attempting to document whether or not income smoothing actually occurs there has been little exploration of why a manager might rationally want to smooth his firm s income explaining why smoothing might be observed and how it can result in an increased stock price is the focus of this paper in two recent studies lambert 1984 and dye 1988 demonstrate in agency settings that a risk averse manager who is precluded from borrowing and lending in the capital markets has an incentive to smooth his firm s reported income in this paper in contrast it is shown that within a market setting an incentive exists for a manager to smooth income that is independent of either risk aversion or restricted access to capital markets the market setting is also useful in that it allows for the analysis of the effect of income smoothing on stock prices it is shown here that if a manager can choose which of two periods to recognize certain income he may prefer the choice that is expected to

asymmetric stationarity in national stock market indices an mtar analysis a procedure is developed using a momentum threshold autoregressive model and asymmetric stationarity tests designed to identify periods of asymmetric stationary divergences from nonstationary paths in time series and is applied to major national stock indices the results reveal the existence of asymmetric stationary periods in each of these indices these results suggest an explanation for the counterintuitive positive forecasting results of technical traders for various time periods we explore this possibility further by using a representative moving average technical trading strategy and find significantly different results higher returns when information from the procedure is incorporated into a trading rule

how do nonprofit hospitals manage earnings abstract we hypothesize that unlike for profit firms nonprofit hospitals have incentives to manage earnings to a range just above zero we consider two ways managers can achieve this they can adjust discretionary spending hoerger t j 1991 profit variability in for profit and not for profit hospitals journal of health economics 10 259 289 and or they can adjust accounting accruals using the flexibility inherent in generally accepted accounting principles gaap to test our hypothesis we use regressions as well as tests of the distribution of earnings by burgstahler and dichev burgstahler d dichev i 1997 earnings management to avoid earnings decreases and losses journal of accounting and economics 24 99 126 on a sample of 1 204 hospitals and 8 179 hospital year observations our tests support the use of discretionary spending and accounting accrual management like hoerger 1991 we find evidence that nonprofit hospitals adjust discretionary spending to manage earnings however we also find significant use of discretionary accruals e g adjustments to the third party allowance and allowance for doubtful accounts to meet earnings objectives these findings have two important implications first the previous evidence by hoerger that nonprofit hospitals show less variation in income may at least partly be explained by an accounting phenomenon second our findings provide guidance to users of these financial statements in predicting the direction of likely bias in reported earnings

on interdependent supergames multimarket contact concavity and collusion abstract following bernheim and whinston 1990 this paper addresses the effects of multimarket contact on firms ability to collude real world imperfections tend to make firms objective function strictly concave and market supergames interdependent firms payoffs in each market depend on how they are doing in others then multimarket contact always facilitates collusion it may even make collusion sustainable in all markets when otherwise it would not be sustainable in any the effects of conglomeration are discussed multigame contact is shown to facilitate cooperation in supergames other than oligopolies as long as agents objective function is submodular in material payoffs journal of economic literature classification numbers c72 d43 l13 l21

implicit contracts and the explanatory power of top executive compensation for future performance recent research suggests that implicit incentive contracts may be based on performance measures that are observable only to the contracting parties we derive and test implications of this insight for the relationship between executive compensation and firm performance if corporate boards optimally use both observable and unobservable to outsiders measures of executive performance and the unobservable measures are correlated with future firm performance then unexplained variation in current compensation should predict future variation in firm performance further compensation should be more positively associated with future performance when observable measures are less useful for contracting our results are consistent with these hypotheses

carbon taxation prices and welfare in new zealand abstract this paper examines the effects on consumer prices arising from imposing a carbon tax in new zealand using information about inter industry transactions and the use of fossil fuels by industries the welfare effects of the carbon tax are examined for a range of different household types finally overall measures of inequality are reported

managerial incentives and collusive behavior abstract i characterize the effects of empirically observed managerial incentives on long run oligopolistic competition when managers have a preference for smooth time paths of profits as revealed by the empirical literature on income smoothing manager led firms can sustain collusive agreements at lower discount factors capped bonus plans and incumbency rents with termination threats make collusion supportable at any discount factor independent of contracts duration when managers have these preferences incentives and demand fluctuates price wars during booms need not occur the most collusive price may then be pro cyclical

additional evidence on bonus plans and income management abstract we extend healy 1985 by examining the relation between discretionary accruals and bonus plan bounds for a sample of 102 firms for the 1980 1990 period contrary to healy we find that when earnings before discretionary accruals fall below the lower bound managers select income increasing discretionary accruals and vice versa we believe that our results are more consistent with the income smoothing hypothesis than with healy s bonus hypothesis however mechanical selection bias in portfolio formation cannot be entirely ruled out as an alternative explanation for our results

smoothing income in anticipation of future earnings abstract recent theory argues that concern about job security creates an incentive for managers to smooth earnings in consideration of both current and future relative performance we find support for this theory our evidence suggests that when current earnings are poor and expected future earnings are good managers borrow earnings from the future for use in the current period conversely when current earnings are good and expected future earnings are poor managers save current earnings for possible use in the future however sensitivity analysis indicates that we cannot rule out selection bias as a potential alternative explanation for our findings

do hedge funds manage their reported returns f or funds with high incentives and more opportunities to inflate returns we find that i returns during december are significantly higher than returns during the rest of the year even after controlling for risk in both the time series and the cross section and ii this december spike is greater than for funds with lower incentives and fewer opportunities to inflate returns these results suggest that hedge funds manage their returns upward in an opportunistic fashion in order to earn higher fees finally we find strong evidence that funds inflate december returns by underreporting returns earlier in the year but only weak evidence that funds borrow from january returns in the following year jel g10 g19 g23 g30

the distribution of material footprints in germany this study investigates the within country heterogeneity of material footprints implied by households consumption in germany material footprints are defined as the amount of biomass minerals and fossil fuels extracted to produce the goods that households consume combining input output data with households consumption expenditures from the german sample survey of income and expenditure evs we present the first comprehensive study on the distribution of material footprints among households highlighting hot spots of unsustainable consumption patterns by household groups households in the quartile with the highest consumption expenditures have material footprints three times as large as those in the quartile with the lowest expenditures results of a microeconomic model of household s consumption behaviour estimated on the evs data suggest that price based instruments can reduce material footprints of luxury consumption such as leisure and private transport without imposing large burdens on low affluence households the material footprints caused by energy consumption do not react sensitively to price changes suggesting that non price policies are more effective to reduce them

the optimal shape of compensation contracts with earnings management the research question of why earnings management occurs is decomposed into two questions in this article which component of executive compensation generates incentives for earnings management and why is the compensation structured that way in the first place we first use as a dynamic stochastic equilibrium model to show that big bath and earning overstatement can co exist as equilibrium financial reporting strategies when thresholds are used in compensation contracts in order to understand the use of performance thresholds as a prevailing compensation strategy in practice we then derive the optimal compensation contract when the manager is privately informed about economic earnings and his expertise in managing earnings equilibria exist in which the inactive region below a threshold in compensation should be economically significant
