the use of unsigned earnings quality measures in tests of earnings management this paper examines the implications of using the absolute value of discretionary accruals when testing for earnings management first we analytically develop the mean and variance of the distribution of absolute discretionary accruals and show that the expected value is an increasing function of the variance in the underlying error term from the first stage discretionary accrual estimation model second we highlight several firm characteristics that are related to the error variance in discretionary accrual estimation models using simulations we show that correlation between the earnings management partitioning variable and these firm characteristics leads to an overrejection of the null hypothesis of no earnings management third we provide research design suggestions to help researchers mitigate the potential bias arising from the use of unsigned measures of earnings management using these suggestions we replicate a recent study and demonstrate that the inferences change after controlling for operating volatility

accounting method choice opportunistic behavior efficient contracting and information perspectives abstract three alternative but not mutually exclusive perspectives on accounting method choice are contrasted the opportunistic behavior efficient contracting and information perspectives much of the empirical work on accounting method choice is based on the opportunistic behavior perspective the malmquist and main and smith papers are attempts to view accounting method choice as a means of improving the monitoring capabilities of contracts which rely on accounting numbers the papers serve as useful vehicles for illustrating the difficulties of delineating a set of maintained assumptions that result in hypotheses about how accounting method choice affects the monitoring characteristics of contracts and distinguishing between hypotheses based on the three perspectives on accounting method choice

partial international coordination in the great fish war this study extends the great fish war model of levhari and mirman levhari d and mirman l 1980 bell journal of economics 11 322 344 by incorporating a multiple country context into the model and investigates the existence of a partial coordination nash equilibrium first findings of this paper suggest that a partial coordination scheme is sustainable only in limited cases any coalition that has more than two member countries cannot be sustained second the existence and the number of coordinating countries depend critically on the magnitude of the biological and preference parameters finally if the coalition is assumed to be a dominant player there always exist one or two welfare improving sustainable coalitions and the size of the sustainable coalitions depends on the parameters of the problem

renewable resource economists and policy what differences have we made abstract this paper surveys developments in fisheries economics and fisheries policy over the past half century early work clarified the nature of the economic issues associated with open access laying the groundwork for changes in policies after coastal nations expanded their jurisdictions in 1976 perhaps the most important point made by economists is that property rights matter and that open access conditions create economic as well as biological problems the policy process has begun to create property rights systems although many of the world s fisheries still operate under mixed systems of regulations and open access incentives

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

dynamic nonpoint source pollution control policy ambient transfers and uncertainty when a regulator cannot observe or infer individual emissions corrective policy must rely on ambient pollution data assuming this kind of environment we study a class of dierential games of pollution control with prot functions that are polynomial in the global pollution stock given an open loop emissions strategy satisfying mild regularity conditions an ambient transfer scheme is exhibited that induces it in markov perfect equilibrium mpe proposed transfers are a polynomial function of the dierence between actual and desired pollution levels moreover they are designed so that in mpe no tax or subsidy is ever levied their applicability under stochastic pollution dynamics is studied for a symmetric game of polluting oligopolists with linear demand we discuss a quadratic scheme that induces agents to adopt markovian emissions strategies that are stationary and linearly decreasing in total pollution total expected ambient transfers are non positive and their magnitude is linearly increasing in physical volatility the size of the economy and the absolute value of the slope of the inverse demand function however if the regulator is interested in inducing a constant emissions strategy then in expectation transfers vanish the total expected ambient transfer is compared to its point source equivalent

tipping points and business as usual in a global commons abstract this paper analyzes a dynamic strategic model of resource extraction from a global commons countries derive benefits from both direct extraction and aggregate conservation of an open access resource each period a country s output depends both on its resource usage and on the global stock of the resource stored within the ecosystem leading examples are ocean fisheries habitat preservation forestry and land carbon biomass the production coefficients on these inputs vary across countries and evolve stochastically over time a business as usual bau equilibrium characterizes each country s resource usage in the absence of an effective international agreement under non concave resource dynamics depletion of the resource in a bau equilibrium may reach a tipping point below which the stock spirals downward toward a steady state of marginal sustainability under the assumptions of the model the tipping points emerge endogenously if the number of extractors exceeds some fixed finite bound the commons always tips regardless of the initial stock we find that countries will accelerate their rates of extraction the closer they are to reaching the low end steady state by contrast in the socially efficient plan the commons never tips if the initial stock is large

detecting earnings management a new approach this paper provides a new approach to test for accrual based earnings management our approach exploits the inherent property of accrual accounting that any accrual based earnings management in one period must reverse in another period if the researcher has priors concerning the timing of the reversal incorporating these priors can significantly improve the power and specification of tests for earnings management our results indicate that tests incorporating reversals increase test power by around 40 and provide a robust solution for mitigating model misspecification arising from correlated omitted variables

truthfulness in accounting how to discriminate accounting manipulators from non manipulators accountants preparing information are in a position to manipulate the view of economic reality presented in such information to interested parties these manipulations can be regarded as morally reprehensible because they are not fair to users they involve in an unjust exercise of power and they tend to weaken the authority of accounting regulators this paper develops a model for detecting earnings manipulators using financial statements ratios in a sample of spanish listed companies our results provide evidence that accounting data can be extremely useful in detecting manipulators this approach can be used by a large category of users of accounting information among which we can cite stock exchange supervisors or investing professionals

earnings management under price regulation empirical evidence from the spanish electricity industry abstract this paper analyses the effect of price regulation on the accounting policy of spanish electricity companies over the period 1991 2001 as predicted by the political costs hypothesis watts and zimmerman 1986 watts r l zimmerman j l 1986 positive accounting theory prentice hall englewood cliffs nj managers artificially reduce reported earnings when the government establishes tariff increases in this way companies attempt to diminish their political visibility and counteract social outcry arising from the government s decision several abnormal accruals models existent in the literature are used to obtain a proxy for managerial accounting discretion on earnings

nash and stackelberg solutions in a differential game model of capitalism abstract this paper examines two noncooperative open loop solution concepts in a simple model of economic growth and distribution formulated as a differential game between workers who may save or consume and capitalists who may consume or invest it is demonstrated that both players prefer the stackelberg game to the nash game furthermore it is shown that under fairly realistic assumptions about the parameters of the model both workers and capitalists would prefer to act as the follower in the stackelberg game this means that capitalism is in a stalemate i e in a position where neither class wants to take the initiative and announce its strategy first the result is interpreted as an explanation of the difficulties met in designing and implementing incomes policies and social contracts

international stock market linkages evidence from the pre and post october 1987 period abstract this paper uses recent developments in the theory of cointegration to provide new methods of testing the linkage and dynamic interactions among stock market movements our findings are in sharp contrast with previous research which discovered strong interdependence among national stock markets prior to october 1987 for the post october 1987 period however our results show that the degree of international co movements among stock price indices has increased substantially with the nikkei index the only exception furthermore the us stock market is found to have a considerable impact on the french german and uk markets in the post crash period we also find the response of the french german and uk markets to us stock market innovations to be consistent with the view of cross border informationally efficient stock markets finally we find the japanese equity market performance to have no links with both the us stock market and the stock markets in france germany and uk during the pre and post october crash period

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

transboundary pollution and household mobility are they equivalent abstract recent research has shown that perfect household mobility can serve as a disciplinary mechanism inducing national policy makers to internalize interregional externalities caused by transboundary pollution this paper develops a differential game to illustrate that the result is not necessarily robust when migration costs and explicit dynamics are introduced the paper shows that if governments constantly reoptimize imperfect household mobility leads to a tragedy of the commons and individual countries overemit even when pollution is purely local moreover these dynamic externalities get worse as the degree of household mobility increases and there is a qualitative difference between almost perfect and perfect mobilty that is a discontinuity at zero migration costs

labor tax avoidance and its determinants the case of mafia firms in italy this paper develops two new measures of labor tax avoidance ltav based on social contribution expenses reported in financial statements and tests them and their determinants within a sample of 224 italian firms defined as legally registered mafia firms lmfs due to having been confiscated at some point by judicial authorities in relation to alleged connections with italian organized crime overall our results reveal that before confiscation lmfs engage more in ltav than lawful firms do whereas after confiscation there is no significant difference between both types of firm furthermore we find that several factors have a significant influence on the probability of engaging in such a practice this study can enhance further research on the effectiveness of our measures and on the determinants of ltav in other contexts and for other types of firms moreover these measures can be added to the other direct and indirect methods commonly employed to measure and detect undeclared work representing a primary means of ltav finally our study allows inferring conclusions on the relation between corporate social responsibility and tax avoidance suggesting that socially irresponsible firms such as lmfs are more likely to adopt this practice

a differential game model of a market of substitutable products abstract modern industrial organization often classifies groups of differentiated products that are fairly good substitutes to belong to the same market this paper develops a differential game model of a market of substitutable products to avoid the problem of time inconsistency we solve a feedback nash equilibrium solution for the game a set of state dependent equilibrium strategies is derived extensions of the model to a stochastic formulation and to an infinite time horizon specification are also provided

the contracting benefits of accounting conservatism to lenders and borrowers abstract this paper examines the ex post and ex ante benefits of accounting conservatism to lenders and borrowers in the debt contracting process i expect conservatism to benefit lenders ex post through the timely signaling of default risk as manifested by accelerated covenant violations and to benefit borrowers ex ante through lower initial interest rates consistent with these predictions i find that more conservative borrowers are more likely to violate debt covenants following a negative price shock and that lenders offer lower interest rates to more conservative borrowers

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

control rights and capital structure an empirical investigation we show that incentive conflicts between firms and their creditors have a large impact on corporate debt policy net debt issuing activity experiences a sharp and persistent decline following debt covenant violations when creditors use their acceleration and termination rights to increase interest rates and reduce the availability of credit the effect of creditor actions on debt policy is strongest when the borrower s alternative sources of finance are costly in addition despite the less favorable terms offered by existing creditors borrowers rarely switch lenders following a violation a fundamental question in financial economics is how do firms choose their financial policies extant empirical research on this question has focused primarily on the presence of taxes and bankruptcy costs e g scott 1976 information asymmetry e g myers and majluf 1984 and more recently market timing behavior e g baker and wurgler 2002 however beginning with jensen and meckling 1976 a large body of theoretical research examines how incentive conflicts between managers and external investors affect corporate financial policies in particular theoretical research on financial contracting shows that in the presence of incentive conflicts optimal debt contracts will allocate certain rights to creditors after negative performance in order to help firms secure financing ex ante e g aghion and bolton 1992 and dewatripont and tirole

differential game models in management science abstract this paper reviews a number of differential games applications to management science and operations research problems published with a few exceptions during the last decade the purpose of the article is to provide the reader with an up to date account of the state of the art within this field after having stated in an introduction the general differential games framework as well as some conceptual problems we proceed to review the models which have been divided into the following functional areas investment consumption and employment production inventories and maintenance marketing advertising pricing and rd bargaining natural resources and pollution the survey concludes with some remarks on applicability solvability and directions for future research

determinants of intramethod choice in the oil and gas industry abstract procedural flexibility can have a substantial impact on reported costs revenues expenses and balance sheet valuations until 1978 oil and gas companies had considerable flexibility in applying full cost and successful efforts a unique opportunity to measure the income effect of firms procedural choices occurred when the sec specified the exact procedures that must be followed by oil and gas producers when they account for exploratory and development costs under both the full cost and successful efforts methods in complying with the new rules firms were required to adjust retained earnings retroactively to reflect what it would have been if the new procedures had been in effect all along these retained earnings adjustments provide a measure of the income effect of procedural choices this study shows that economic incentives influence the procedural accounting choices which were made by oil and gas producers the same economic incentives also influence the choice of full cost or successful efforts finally the discriminatory ability of firms economci incentives is most powerful when firms reporting strategies are defined in terms of both choice of accounting methods and procedural applications within those methods

languages and earnings management abstract we predict that managers of firms in countries where languages do not require speakers to grammatically mark future events perceive future consequences of earnings management to be more imminent and therefore they are less likely to engage in earnings management using data from 38 countries we find that accrual based earnings management and real earnings management are less prevalent where there is weaker time disassociation in the language our study is the first to examine the relation between the grammatical structure of languages and financial reporting characteristics and it extends the literature on the effect of informal institutions on corporate actions

earnings quality research advances challenges and future research abstract this discussion makes several observations regarding the earnings quality research reviewed in dechow ge and schrand 2010 dgs i discuss some of the factors that led to the large growth in the earnings quality literature over the past two decades and note a few of the important contributions from this literature i also present what i view as several major challenges the literature faces as well as some avenues for future research in addition i discuss the difficulties in evaluating such a diverse body of literature and comment on dgs s major conclusions

does religion mitigate earnings management evidence from china using a sample of 11 357 firm year observations from the chinese stock market for the period of 2001 2011 we investigate whether and how religion can mitigate earnings management specifically based on geographic proximity based religion variables we provide strong and robust evidence to show that religion is significantly negatively associated with the extent of earnings management suggesting that religion can serve as a set of social norms to mitigate corporate unethical behavior such as earnings management our findings also reveal that the negative association between religion and earnings management is less pronounced for firms with closer distance to the regulatory centers than for their counterparts implying the substitutive effects between religion and the distance to regulators the proxy for regulatory intensity on mitigating earnings management the above results are robust to different measures of earnings management various religion variables and a variety of sensitivity tests

stackelberg versus cournot a differential game approach abstract we propose an infinite horizon differential oligopoly game where at each point in time m stackelberg leaders and n m stackelberg followers exploit a common pool renewable resource and sell their harvest in the marketplace at a price that depends on total harvest we derive a feedback generalized stackelberg nash cournot equilibrium a generalization of the feedback stackelberg equilibrium nesting feedback stackelberg and feedback cournot as special cases we proceed with a comparison between the feedback stackelberg and the feedback cournot equilibria and find a number of interesting results in contrast with static oligopoly theory as to the relative efficiency of the two equilibria we show that the cournot equilibrium can be more efficient than the stackelberg equilibrium this holds true in the short run at the steady state and in terms of discounted welfare

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

international fisheries agreements a game theoretical approach this paper surveys the application of game theory to the economic analysis of international fisheries agreements the relevance of this study comes not only from the existence of a vast literature on the topic but especially from the specific features of these agreements the emphasis of the survey is on coalition games an approach that has become prominent in the fisheries economics literature over the last decade it is shown that coalition games were first applied to international fisheries agreements in the late 1990s addressing cooperative issues under the framework of characteristic function games then progressively this cooperative approach was combined with non cooperative elements such as the stability analysis of the agreements finally partition function games which model coalition formation endogenously were introduced and became the standard approach to study the formation and stability of international fisheries agreements a key message that emerges from this literature strand is that self enforcing cooperative management of internationally shared fish stocks is generally difficult to achieve hence the international legal framework and regulations play a decisive role on ensuring cooperation over the use of these resources

managing interacting species in unassessed fisheries abstract this paper addresses the management of multispecies fisheries and suggests the use of restricted fishing policies as an interesting option for unassessed fisheries as is the case within developing countries specifically we consider a predator prey system under two potential management policies an unrestricted regime where agents can compete to harvest from both species and a second one where they are allowed to harvest only predators the performance of both policies is compared from an ecological and an economic point of view for a sufficiently large number of agents or for strong biological interaction parameters the assumed restricted fishing policy yields both higher long run stock levels and profits thus this contribution suggests that such a policy while requiring weaker monitoring governance than instruments based on outputs such as quotas or taxes would meet environmental and economic objectives finally several features of the analysis are discussed including targeting prey instead of predator and the issue of compliance

marine ecosystem considerations and second best management we compare how the long run distribution of fishing activities is affected in multispecies fisheries when facing different second best control rules 1 species specific landing regulation and 2 global input regulation we show how this depends on the economic returns and on the type of ecological interaction considered we highlight specifically that fishing effort does not necessarily increase on nontargeted species and decrease on targeted species and that the characterization of second best efficient instruments may differ drastically depending on the nature of the interaction

debt covenant violations and managers accounting responses abstract this paper examines accounting changes costs of default and accounting based covenants violated by 130 firms reporting violations in annual reports i find that managers of firms approaching default respond with income increasing accounting changes and that the default costs imposed by lenders and the accounting flexibility available to managers are important determinants of managers accounting responses i also document that private lending agreements are the first violated that net worth and working capital restrictions are the most frequently violated restrictions and that in 52 percent of the cases lenders require concessions from borrowers to resolve default

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

determinants of the corporate decision to capitalize interest abstract until 1974 firms could choose within gaap to capitalize or expense interest costs associated with capital expenditures the predominant practice had been to treat interest as a period expense however in 1974 the securities and exchange commission imposed a moratorium on further adoption of interest capitalization by non regulated firms this study empirically examines economic factors potentially influencing firms decisions to expense or capitalize interest prior to the sec moratorium we hypothesize that the choice may be affected by 1 the existence of management compensation agreements tied to reported earnings 2 debt covenant constraints and 3 the political costs for some firms of reporting higher earnings when compared to the control group our findings are that 1 the frequency of explicit management compensation packages was not greater for the interest capitalization group 2 firms with financial ratios closer to likely debt agreement constraints on dividends interest coverage and leverage tended to elect interest capitalization and 3 other than the largest firms in the politically sensitive petroleum refining industry the larger firms were more likely to capitalize interest

accounting information in financial contracting the incomplete contract theory perspective this paper reviews theoretical and empirical work on financial contracting that is relevant to accounting researchers its primary objective is to discuss how the use of accounting information in contracts enhances contracting efficiency and to suggest avenues for future research we argue that incomplete contract theory broadens our understanding of both the role accounting information plays in contracting and the mechanisms through which efficiency gains are achieved by discussing its rich theoretical implications we expect incomplete contract theory to prove useful in motivating future research and in offering directions to advance our knowledge of how accounting information affects contract efficiency

a stochastic differential fishery game for a two species fish population with ecological interaction we combine and extend two existing lines of research in game theoretic studies of fisheries building up on quirk and smith 1977 anderson 1975 fisher and mirman 1996 sumaila 1997 and most recently datta and mirman 1999 who developed either static or discrete time models not including ecological uncertainty and jorgensen and yeung 1996 who do include uncertainty but do not capture any features of ecological interaction in this article we develop a continuous time framework where ecological interaction is described by a stochastic dynamics including the cases of predator prey and competition we obtain a stochastic differential game and derive markov feedback nash equilibrium strategies in semi analytic form furthermore we compare the results with the case where fisheries regulations restrict each fishery to harvest only one species and study the inefficiencies which arise from this in addition to that we also consider the case where fisheries cooperate here we observe quite different effects on the ecosystem depending on whether the system is competitive or predator prey

measuring the probability of financial covenant violation in private debt contracts we measure the probability that a borrower will violate financial covenants in private debt contracts we analyze hand coded data and specify standard covenant definitions using compustat data that minimize measurement error for all individual dealscan covenants we use these definitions to create a measure of aggregate probability of violation which can be used across all covenants in a loan or among covenant subsets of interest we provide evidence that our aggregate probability measure is superior to alternatives used in prior literature

exploring the manipulation toolkit the failure of doral financial corporation abstractthe 2015 bankruptcy of doral financial corporation once the best u s bank according to u s banker is the largest since april 2010 the bankruptcy concludes years of management manipulation and efforts to recover sec investigation revealed fraud related to doral s valuation of interest only strips ios we show that doral management s misconduct also includes reckless hiring over investing insiders trading and opportunistic stock splits investigating the full range of doral management s misconduct reveals new tactics that managers use to pool with good firms and aids our understanding of the economic impact of managerial misconduct

equilibria in a stochastic resource management game under imperfect information abstract the paper considers equilibrium solutions in a stochastic resource management game the countries choose frequently between cooperative and noncooperative retaliation modes of play the choices between cooperative and noncooperative subgames are based on imperfect estimates of the fishing efforts fleet sizes of the co harvesting country during the previous period if either of the countries concludes that the fishing activity of the co harvesting country has been too intensive during the previous period i e the estimated fishing effort exceeds a trigger value then either a noncooperative retaliation period follows or cooperation is continued after a noncooperative period the countries begin to cooperate once again it is shown that equilibria in which cooperative and noncooperative periods alternate can occur in dynamic games different types of equilibria for the game exist the countries may be able to sustain efficient cooperation all the time they may oscillate between cooperation and noncooperation or they may fail to cooperate at all conditions under which an equilibrium coincides with a pareto optimal solution are studied

efficiency tests in the french derivatives market abstract the french derivatives market the marche a terme international de france matif or the french international futures and options exchange is one of the major derivatives markets in the world the efficiency of four financial contracts traded on the matif cac40 index futures ecu bond futures national bond futures and pibor 3 month futures are examined in this paper test results from serial correlations unit root tests and variance ratio tests provide overwhelming evidence that the random walk hypothesis cannot be rejected for these contracts

the effects of debt covenants and political costs on the choice of accounting methods the case of accounting for r d costs abstract until 1974 firms could capitalize or expense all or part of their research and development r d costs managerial choice between these two alternatives is hypothesized to be affected by the existence of debt covenants which employ accounting numbers relating to leverage interest coverage and ability to pay dividends in addition the use of public versus private debt is hypothesized to affect the accounting choice due to differential renegotiation costs lastly a political cost hypothesis is tested this study uses a multivariate statistical technique the generalized jackknife the results suggest that firms which capitalized r d costs were more highly levered used more public debt were closer to dividend restrictions and were smaller than firms which expensed r d costs

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

noncooperative solutions for a differential game model of fishery abstract in this paper a generalization of gordon schaefer s fishery resource model to a duopoly is presented the resulting noncooperative game is solved analytically as well as numerically by using the equilibrium concepts of nash and stackelbewrg it turns out that in both cases the player with the smaller unit costs is able to choose a higher catch rate than his opponent furthermore it is shown that the game is stackelberg dominant in the stackelberg case any information disadvantage in the sense of stackelberg fellowership can be eliminated by a more efficient technology

strategic exploitation of a common resource under environmental risk abstract we study the effect of environmental risk on the extraction of a common resource using a dynamic and non cooperative game in which an environmental event impacts the renewability and the quality of the resource we show that the anticipation of such an event has an ambiguous effect on extraction and the tragedy of the commons a risk of a reduction in the renewability induces the agents to extract less today while a risk of a deterioration in the quality has the opposite effect moreover when environmental risk induces conservation the tragedy of the commons is worsened

the effect of owner versus management control on the choice of accounting methods abstract this paper examines the relationship between the ownership control status of firms and the accounting methods they adopt the arguments of watts and zimmerman s positive theory are integrated with those of managerial economists to generate the prediction that management controlled firms are more likely than owner controlled firms to adopt accounting methods which increase reported earnings this prediction is inconsistent with fama s hypothesis that the market for managerial talent will prevent management controlled firms from acting differently than owner controlled firms this paper compares the depreciation methods used by a sample of management and owner controlled firms for financial reporting purposes the comparison considers and controls for the factors of firm size leverage and the depreciation method used for tax reporting purposes the comparison reveals that there is a significant difference in the depreciation methods adopted by management controlled and owner controlled firms for financial reporting purposes

the impact of performance based compensation on misreporting abstract this paper examines the effect of ceo compensation contracts on misreporting we find that the sensitivity of the ceo s option portfolio to stock price is significantly positively related to the propensity to misreport we do not find that the sensitivity of other components of ceo compensation i e equity restricted stock long term incentive payouts and salary plus bonus have any significant impact on the propensity to misreport relative to other components of compensation stock options are associated with stronger incentives to misreport because convexity in ceo wealth introduced by stock options limits the downside risk on detection of the misreporting

ultimate ownership income management and legal and extra legal institutions this study provides evidence of the role of both legal and extra legal institutions in limiting the income management induced by the detachment of control rights from the cash flow rights of ultimate owners the tests use a unique comprehensive data set for firm level control and ownership structures from 9 east asian and 13 western european countries univariate regressions show that income management that is induced by the wedge between control rights and cash flow rights is significantly limited in countries with high statutory protection of minority rights proxied by legal tradition minority rights protection the efficiency of the judicial system or disclosure standards and effective extra legal institutions proxied by the effectiveness of competition laws diffusion of the press and tax compliance furthermore multiple regression results show that a common law tradition and an efficient judicial system subsume the effects of the other legal institutions and that a high rate of tax compliance subsumes the effects of the other extra legal institutions in curbing insider income management it is surprising that a high rate of tax compliance ultimately has a greater effect than legal tradition and the efficiency of the judicial system although this finding is unexpected given prior evidence on the dominant roles of legal institutions in macroeconomic issues and corporate policies it is consistent with the recent argument that effective tax enforcement is like a public good in that it can reduce insiders private control benefits an implication of this finding is that closer attention to extra legal institutions has the potential to enhance our understanding of the institutional reforms needed to limit insider private control benefits

an empirical examination of debt covenant restrictions and accounting related debt proxies abstract prior studies of discretionary accounting choices have generally relied on one or more proxy variables to measure closeness to debt covenant restrictions without actually examining the existence or extent of restrictive covenants this study tests the validity of the most commonly used proxy the debt equity ratio by examining its relation to actual debt covenant restrictions for a random sample of u s firms the results indicate that several versions of the debt equity ratio capture the existence and tightness of retained earnings restrictionsand the existence of net tangible asset and working capital restrictions but are unrelated to four other covenant restrictions

strategic resource extraction capital accumulation and overlapping generations abstract the standard resource extraction framework assumes infinitely lived agents and yields an overfishing result for some applications a finite time horizon may be more appropriate a direct extension of the levhari mirman model to overlapping generations yields an extreme overfishing result alternatively we assume young and old specialize and respectively fish and supply capital in this model under some circumstances there may well be under utilization of natural resources however for a given production technology if there are a sufficiently large number of agents overfishing always results

debt covenants and accounting choice abstract in this issue duke and hunt and press and weintrop show that leverage is significantly related to the existence of and closeness to accounting based debt covenants alternative rationales for this relation are presented the theory requires more rigorous specification to define closeness to covenants and determine which measure of leverage produces a more appropriate proxy for closeness to covenants then healy and palepu investigate a sample of firms close to their dividend restriction and find in general they are no more likely than other firms to change accounting methods their sample selection criteria reduces the generalizability of their results

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

legal inforcement short maturity debt and the incentive to manage earnings abstract prior research contends that weak legal regimes discourage lender enforcement of contracts by making it either costly or ineffective however diamond observes that this lender passivity can be overcome by structuring debt as a short term loan his argument is that an arrival of bad news in the presence of short term debt can result in externalities that will trigger a run on the firm and that this in turn creates ex ante incentives for lenders to enforce their contracts we examine whether short term debt creates an incentive for borrowers to delay the recognition of bad news through earnings management using a sample of firm level data from 33 countries over a 10 year period we find that short term debt induces greater earnings management this impact of short term debt is especially greater in countries with weak legal regimes this evidence is consistent with the hypothesis that borrowers will manage earnings to circumvent lender enforcement

accounting for interest by real estate developers this paper investigates accounting for interest by australian real estate developers it argues that management s choice of accounting technique is the result of ex ante contracting to prevent management opportunistic behavior rather than a manifestation of opportunistic behavior per se the argument provides a richer description of accounting choice and explains why in australia leverage and the accounting method choice are correlated in the absence of bond covenants the argument also explains why inconsistent with political cost arguments larger firms are more likely to capitalize than expense interest

why new issues and high accrual firms underperform the role of analysts credulity we find that analysts forecast errors are predicted by past accounting accruals adjustments to cash flows to obtain reported earnings among both equity issuers and nonissuers analysts are more optimistic for the subsequent four years for issuers reporting higher issue year accruals the predictive power is greater for discretionary accruals than nondiscretionary accruals and is independent of the presence of an underwriting affiliation predicted forecast errors from accruals significantly explain the long term underperformance of new issuers the predictability of forecast errors among nonissuers suggests that analysts credulity about accruals management more generally contributes to market inefficiency copyright 2002 oxford university press

the effect of ethical orientation and professional commitment on earnings management behavior the purpose of this study is twofold the first objective is to examine the impact of an individual s ethical ideology and level of professional commitment on the earnings management decision the second objective is to observe whether the presence of a personal benefit affects an individual s ethical orientation or professional commitment within the context of an opportunity to manage earnings using a sample of 375 undergraduate business majors our results suggest a significant relationship between an individual s ethical orientation and decision making further participants with higher levels of professional commitment seem to be less likely to engage in earnings management behavior and less likely to behave opportunistically these results have the potential to add to our understanding of certain behaviors in entry level personnel and should be of interest to managers practitioners academicians and researchers

the compleat fish wars biological and dynamic interactions abstract in this article we study an example of a fishery in which there are two agents each harvesting two species of fish there are two externalities in the model the dynamic externality studied in levhari and mirman 1980 and the biological externality examined in fischer and mirman 1992 this model allows us to study the interactions between agents in a model in which the species of fish interact we find the unique closed loop nash equilibrium in the context of a differential game and we compare the resulting catch ratios to the results of the earlier papers which allow for only one externality we also study the efficiency of the solution

externalities trade and dynamics with expanding global trade countries around the world are becoming increasingly interdependent the necessity for the governments to devise economic policies strategically with respect to the world is therefore becoming more important however at the same time there are various sectors of economies that are competitive and thus not strategic since they are in a competitive environment agents in these sectors do not perceive the influence of their decisions on the world economy and act nonstrategically of course government policies affect all sectors hence economies are mixed having both strategic and nonstrategic components it is worthwhile to point out some examples of this type of mixed economy in western capitalist countries interest rates and exchange rates are determined in a competitive market while monetary and fiscal policies an integral part of the determination of these rates are controlled by governments the government decides on the amount of aggregate resources to be allocated for education and research and development research is often carried out by individuals or firms and there is a competitive market for the products generated by it another example can be found in the fishing industry government policies dictate the maximum amount of fish that can be extracted from the ocean while there is a conmpetitive market in fish along with the dual nature of decision making the above examples have another feature in common there are externalities between the policy makers decisions these externalities imply that there are interdependences among the countries so that the decisions of each of the countries have effects on the outcome of the competitive market the competitive outcome in turn affects the decisions of the policy makers in the various countries in the example of the monetary sector money supply in one country affects the rate of interest in the domestic country as well as abroad to properly

common stochastic trends in a system of eurocurrency rates abstract this paper investigates the temporal relationship between interest rates on eurodeposit instruments ranging in maturity from seven days to one year for seven different currency denominations over the 1986 1992 period multivariate tests of cointegration reveal strong evidence in favor of the presence of common factors in the univariate time series representation of each eurocurrency term structure specifically the hypothesis of noncointegration was rejected in all seven eurocurrency term structures of interest rates examined in this study this is consistent with the hypothesis that each eurocurrency term structure of interest rates possesses a cointegrating structure that prevents these rates from drifting too far apart from equilibrium so that profitable opportunities do not persist the estimation of an error correction model which used this information i e the cointegrating equilibrium error term produced interest rate forecasts that outperformed the forecasts of a naive and a var model that ignore the cointegration of eurodeposit rates finally we examined the extent of interdependence among five maturities of seven dimensional intercurrency eurodeposit rate series and found a strong cointegrating structure across intercurrency eurodeposit rates that forces convergence among these rates

an income strategy approach to the positive theory of accounting standard setting choice abstract this paper is designed to provide additional evidence on the positive theory of accounting policy choice by combining individual accounting principles into firm income strategies these strategies were the dependent variable in a probit analysis where the independent variables were size management compensation industry concentration ratio systematic risk capital intensity and the total debt to total asset ratio the results indicate that four of these factors size management compensation concentration ratio and the total debt to total asset ratio have a significant association with the choice of a firm s income strategy this test provides strong evidence consistent with the positive theory of accounting standard setting choice we also present evidence that smaller firms and or firms in less concentrated industries do not appear to make accounting policy choice decisions that are consistent with this theory

exploring the impact of internal corporate governance on the relation between disclosure quality and earnings management in the uk listed companies this study investigates the impact of internal corporate governance on the relation between disclosure quality and earnings management in the uk listed companies in particular whether governance mechanisms have deterrent effect on earnings management similar to firms disclosure quality unlike prior literature we measure a number of board and audit committee related governance instruments three disclosure quality proxies i e investor relation magazine award forward looking disclosure and analyst forecast accuracy and the modified jones model to test the hypotheses of the study on a matched pair sample data of investor relation magazine award winning and non winning firms our findings in the ols and sensitivity analyses using heckman procedure and 2sls regressions consistently report a significant negative association between earnings management and disclosure quality for all proxies in restraining earnings management in contrast corporate governance variables are mostly insignificantly related to earnings management this provides an emerging trend of the outperformance of disclosure quality over internal governance mechanisms in lessening earnings management these findings warrant due attention of the policy makers investors corporate firms and other stakeholders in shaping a high quality disclosure and governance regime in corporate settings to mitigate managerial manipulations of earnings across the countries in the world

comparing abnormal accruals models a non parametric approach the purpose of this study is to compare the distribution of discretionary accruals produced by the standard and modified jones models using a non parametric approach evidence is provided that discretionary accruals produced by the two models have an almost identical distribution moreover it is found that whether or not an intercept is included in the model produces more intra distribution mobility than the use of the standard or the modified version of the model

can negotiations prevent fish wars abstract the standard alternating offer model is extended by integrating it with the levhari and mirman fish war model in order to investigate negotiations over fish quota the disagreement actions are endogenous the interior and linear markov perfect equilibrium mpe results in immediate agreement on an efficient path of fish quota this mpe is not analytically tractable numerical solutions show that patience is a disadvantage in this mpe and small differences in patience lead to large asymmetries in the bargaining outcome

dynamic cournot competitive harvesting of a common pool resource a variant of the classical harvesting game where a number of competing agents simultaneously harvest a common pool natural resource is analysed the harvesting at each time is a cournot competition the critical assumption made in the present analysis is that most or all individual participants maintain a perspective which is wholly myopic three cases are analysed 1 the case of aggressive myopic cournot competition 2 co operation and 3 competition when there is an incumbent player the development in the number of active participants is outlined and stability criteria for a dynamic cournot competitive game are given the exact deadweight loss due to lack of co operation is calculated 2003 elsevier b v all rights reserved

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

accruals management investor sophistication and equity valuation evidence from 10 q filings the release of the full set of financial statements in form 10 q provides investors with the data necessary to estimate the discretionary portion of earnings thereby allowing them to better assess the integrity of reported quarterly earnings we thus expect a negative association between unexpected discretionary accruals estimated using 10 q disclosures and stock returns around 10 q filing dates consistent with our expectations we document a negative association between unexpected discretionary accruals and cumulative abnormal returns over a short window around the 10 q filing date furthermore this association varies systematically with investor sophistication finally results from portfolio tests indicate that this association is economically as well as statistically significant one interpretation of our findings is that accruals management has substantial valuation consequences which are quickly impounded into stock prices

on the markovian efficiency of bertrand and cournot equilibria we characterize and compare closed loop feedback price and quantity strategies within a full fledged dynamic model of oligopolistic competition in which production requires exploitation of a renewable productive asset unlike previous papers on the strategic exploitation of productive assets we allow for imperfect product substitutability which enables us to deal with price competition we show that the traditional result that the bertrand equilibrium is more efficient than the cournot equilibrium does not necessarily hold in a markovian environment either in the short run or at the stationary equilibrium or using the discounted sum of welfare as a criterion for relative efficiency

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

the treasury yield curve as a cointegrated system this paper examines the temporal relationship between interest rates on treasury securities ranging in maturity from three months to 30 years we find strong empirical support that the seven treasury rates selected are cointegrated a conclusion that is insensitive to the normalization chosen in particular the hypothesis of noncointegration is rejeeted decisively regardless of the rate selected as the dependent variable in the cointegrating equation to determine whether this information can be used to improve forecasts of treasury rates the seven rates are forecasted with a corresponding erroreorrection model that is shown to outperform an augmented var model that ignores the cointegration of the rates the results are consistent with the belief that arbitrage limits the extent to which rates on different maturities of a given security diverge in addition the results confirm the appropriateness of imposing a common stochastic process for interest rates in equilibrium models of the term structure

entry deterrence and overexploitation of the fishery abstract two stackelberg game models open access and restricted entry of a poaching fishery situation are proposed only the long run noncooperative solution of managing resource stocks is assumed feasible the optimal stock under open access for poachers is shown to be lower than under restricted entry and the latter to be lower than under exclusive ownership deterrence is completely successful under open access but is partially successful only under restricted entry the game models considered are shown to be equivalent to a constrained ownership fishery control problem or its surrogate

oligopoly exploitation of a private property productive asset abstract in this paper we build a closed loop nash equilibrium of a private property productive asset oligopoly we compare and contrast private with common property in terms of exploitation rates and social welfare and provide a comparative dynamic analysis with respect to the number of firms in the industry contrary to previous studies on oligopolistic exploitation of productive assets before exploitation begins the resource is parcelled out each firm privately owns and manages the assigned parcel over the entire planning horizon compared with the common property regime we find a new set of results both in the short and in the long run as for social welfare we provide conditions on the implicit growth rate and the initial asset stock under which the socially optimal allocation of the resource implies a natural monopoly

common stochastic trends in a system of exchange rates univariate tests reveal strong evidence for the presence of a unit root in the univariate time series representation for seven daily spot and forward exchange rate series furthermore all seven spot and forward rates appear to be cointegrated that is the forward premiums are stationary and one common unit root or stochastic trend is detectable in the multivariate time series models for the seven spot and forward rates respectively this is consistent with the hypothesis that the seven exchange rates possess one longrun relationship and that the disequilibrium error around that relationship partly accounts for subsequent movements in the exchange rates a general consensus has emerged in recent years that many macroeconomic time series such as gnp consumption expenditures disposable income etc can be characterized by a stochastic trend model in particular nelson and plosser 22 described this property as one of being difference stationary so that the first difference of a time series is stationary an alternative trend stationary model where a stationary component is added to a deterministic trend term has generally been found to be less appropriate 1 similarly it has long been recognized that many financial time series such as foreign exchange rates are nonstationary e g in meese and singleton 21 the issue of nonstationary is not merely a statistical curiosity but has several important implications for the modeling of exchange rates for instance many models of exchange rate determination under rational expectations require stationarity assumptions when solving out the expected future values of the fundamentals further there has been some controversy over the appropriate transformations to use when conducting tests of whether the forward rate is an unbiased and efficient predictor of the future spot exchange rate 2 some authors e g frenkel 11 12 have conducted tests in levels while geweke and feige 14
