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

labour supply and saving under uncertainty this article examines how variations in labour supply can be used to self insure against wage uncertainty and the impact of such self insurance on precautionary saving the analytical framework is a two period model with saving and labour supply decisions where preferences are consistent with balanced growth the main findings are that i labour supply flexibility raises precautionary saving when future wages are uncertain and ii uncertainty about future wages raises current labour supply and reduces future labour supply

residential demand for energy commodities a household production function approach abstract this paper formulates a demand model for energy commodities using a household production function approach the model is stated in a utility maximization framework where utility is assumed to be a function of two composite commodities directly yielding utility electricity and natural gas are used as inputs along with a capital stock to produce one of the utility yielding commodities the other utility yielding commodity is assumed to be produced with two non energy goods and capital stock which are purchased on the market the kuhn tucker conditions are then used to characterize the optimal time paths for input purchases and investments by the household

labor supply under wage uncertainty abstract we consider an agent in an atemporal setting facing an increase in the uncertainty of her uncertain wage more labor is supplied given small initial wage uncertainty by a person with a ces utility function with an elasticity greater than unity we relate this result to an extended measure of decreasing relative risk aversion a cobb douglas person makes no change in her labor supply in response to increased wage uncertainty

taxation insurance and precautionary labor we examine optimal taxation and social insurance with adverse selection in competitive insurance markets in a previous literature it has been shown that with perfect insurance markets social insurance improves welfare since it is able to redistribute without creating distortions this result has been taken as robust to the introduction of adverse selection as this would only provide additional justifications for social insurance we show however that adverse selection can weaken the case for social insurance compared to a situation with perfect markets whenever social insurance mitigates private underinsurance it also causes welfare reducing effects by decreasing precautionary labor supply and hence tax revenue in addition adverse selection may reduce the redistributive potential of social insurance we illustrate our general results using different equilibrium concepts for the insurance market notably we derive conditions under which a complete renunciation of social insurance is optimal and the government only relies on income taxation to achieve its redistributive objectives

investments in human capital wage uncertainty and public policy abstract the importance of risk characteristics of human capital for the design of tax and education policy is explored wages are uncertain and education while increasing the expected wage may increase or decrease wage variance the government has strong reasons to encourage human capital formation in the latter case partly due to the insurance effect of human capital and partly due to the way the individuals under a plausible restriction on prudence respond to changes in risk the analysis is illustrated using two models of education one where education helps the individuals make better occupational choices and a standard risk augmented becker type model

remittance income volatility and labor supply in mexico author affiliation catalina amuedo dorantes camuedod mail sdsu edu corresponding authorsusan pozo susan pozo wmich edu acknowledgment we would like to thank the anonymous referees and the editor for their comments and suggestions on how to improve the manuscript 1 background and significancea significant body of academic and policy research analyzes the impact of international remittances the earnings that emigrants send home in economies around the globe studies have been carried out to ascertain the effect of remittances on a wide range of economic outcomes including household decisions concerning capital accumulation health and housing expenditures country exchange rates economic growth income distribution poverty rates and as we do in this study labor supply evidence of the impacts of remittances on the well being of recipients and on economic progress is mixed some studies find that countries and households reap positive benefits from these resource transfers e g adam and page 2005 while others find negative or ambiguous effects e g narayan narayan and mishra 2011 an overall consensus on the impacts of remittances is unlikely to emerge for some time given the complexity of this research topic not to mention the varying characteristics of countries under analysis 1we propose to contribute to this important debate using an expanded approach for assessing the effects of remittances on individual and household decision making our contribution is to note that while the level of resource transfers received by the household is likely to influence individual and household behaviors volatility with regard to the stream of inflows is also likely to play an important role to date research on the impact of remittances on remittance receiving households has tended to focus on the way in which the level of remittance inflows affects either individual or household behavior without considering the volatility surrounding these inflows however if the volatility that surrounds remittance inflows influences individual and household behaviors a strategy that only examines the level of inflows is likely to miss out on a more complete understanding of the effects of remittances on individual and household decision making and therefore of their impacts on remittance receiving economies amuedo dorantes and pozo 2010 in this study we focus on the labor market and investigate how volatility of remittance inflows influences male and female labor supply a crucial dimension in the influence of remittances on remittance receiving countries limited numbers of studies have examined the impact of the incidence and level of remittance income on labor supply patterns although conclusions differ owing in part to the various data sources and methodological approaches being used a majority of the studies have concluded that the receipt of remittances results in labor supply reductions for instance rodriguez and tiongson 2001 report that remittances lower employment in the philippines while funkhouser 1992 estimates that remittances reduce the employment likelihood of nicaraguan men and women by 2 and 5 percentage points respectively studies by amuedo dorantes and pozo 2006 and hanson 2007 found that the impact of remittances on the labor supply of mexicans is conditioned on gender they conclude that mexican women reduce labor supply on account of remittance inflows whereas men do not in contrast limiting their study to mexican households that receive persistent remittances cox edwards and rodriguez oreggia 2009 conclude that remittances have no impact on the labor supply of household members remaining in mexico with the exception of urban women in traditionally low migration states for whom labor supply rises however we still lack an understanding of the ways in which the volatility in remittance inflows can impact labor supply in remittance receiving countries

the contribution of l c gray to the economic theory of exhaustible natural resources and its roots in the history of economic thought abstract the paper opens with an assessment of natural resources economics up to 1913 14 when gray published his two pioneering articles in natural resources economics part i an in depth study of gray weighing his contribution to the microeconomic theory of the mine and the macroeconomic theory of conservation against current literature constitutes the main body of the paper part ii gray and hotelling s contributions to the theory of the mine are compared part iii the paper concludes with a comparison drawn between the author s findings and the scant attention previously paid to gray s contributions to natural resources economics so far as i know this is the first attempt to apply economic theory to this particular problem of conservation h c taylor unpublished letter to c r van hise may 23 1913 a reference to gray s economic possibilities of conservation

financial reporting tax costs and book tax conformity abstract we investigate the role of book tax conformity in firms financial reporting activities using a unique set of publicly traded firms that were forced to switch for tax purposes from the cash method to the accrual method prior to the mandated change little trade off existed between tax planning and financial reporting goals for these firms after the change recognition criteria for tax and financial reporting purposes became more alike increasing the trade off between financial reporting and tax objectives our results suggest that required use of the accrual method for tax purposes causes firms to defer income for financial statement purposes

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

scarcity growth and r d abstract the limits to economic growth due to resource scarcity can be alleviated only by the development of backstop substitutes this paper combines resource based economic growth with r d to reduce the cost of backstop technologies characterizing the entire dynamics of optimal growth and r d processes we find that an economy s growth prospects depend on its type as determined by its production technology and learning ability and by its knowledge capital endowment a wide variety of growth patterns emerges ranging from cases in which an economy that without r d eventually stagnates converges to a steady state is diverted by r d onto a path of sustained growth to cases in which r d is not warranted resource scarcity is shown to encourage r d due to the increased reliance on the backstop technology

the rebound effect microeconomic definitions limitations and extensions abstract the rebound effect results in part from an increased consumption of energy services following an improvement in the technical efficiency of delivering those services this increased consumption offsets the energy savings that may otherwise be achieved if the rebound effect is sufficiently large it may undermine the rationale for policy measures to encourage energy efficiency the nature and magnitude of the rebound effect is the focus of long running dispute with energy economics this paper brings together previous theoretical work to provide a rigorous definition of the rebound effect to clarify key conceptual issues and to highlight the potential consequences of various assumptions for empirical estimates of the effect the focus is on the direct rebound effect for a single energy service indirect and economy wide rebound effects are not discussed beginning with khazzoom s original definition of the rebound effect we expose the limitations of three simplifying assumptions on which this definition is based first we argue that capital costs form an important part of the total cost of providing energy services and that empirical studies that estimate rebound effects from variations in energy prices are prone to bias second we argue that energy efficiency should be treated as an endogenous variable and that empirical estimates of the rebound effect may need to apply a simultaneous equation model to capture the joint determination of key variables third we explore the implications of the opportunity costs of time in the production of energy services and highlight the consequences for energy use of improved time efficiency the influence of time costs on the rebound effect and the existence of a parallel rebound effect with respect to time each of these considerations serves to highlight the difficulties in obtaining reliable estimates of the rebound effect and the different factors that need to be controlled for we discuss the implications of these findings for econometric studies and argue that several existing studies may overestimate the magnitude of the effect

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

on the use of instrumental variables in accounting research abstract instrumental variable iv methods are commonly used in accounting research e g earnings management corporate governance executive compensation and disclosure research when the regressor variables are endogenous while iv estimation is the standard textbook solution to mitigating endogeneity problems the appropriateness of iv methods in typical accounting research settings is not obvious drawing on recent advances in statistics and econometrics we identify conditions under which iv methods are preferred to ols estimates and propose a series of tests for research studies employing iv methods we illustrate these ideas by examining the relation between corporate disclosure and the cost of capital

risk and farm operator labour supply this study uses a large increase in us federal crop insurance subsidies as a natural experiment to identify the importance of risk for farm operator labour supply subsidy increases induced greater crop insurance coverage which in turn reduced farmers financial risks crop insurance participation data are merged with farm level census of agriculture data from 1992 and 1997 to compare how individuals off farm labour supply changed in response to the policy induced change in insurance coverage the empirical approach controls for unobserved heterogeneity and accounts for the censored nature of the data it is found that greater insurance coverage reduces the off farm labour supply of operators who produced at least 100 000 of output and increased the labour supply of small farm operators who produced less than 25 000 of output

the taxable and book income motivations for a lifo layer liquidation this study examines the potential determinants of lifo liquidations using a multivariate tobit model 1 unlike the univariate analysis used in prior lifo liquidation studies e g davis kahn and rozen 1984 and tse 1990 our multivariate analysis takes into account both the correlations among these potential determinants and the magnitude of lifo liquidations simple correlation analysis indicates that the sales changes and earnings changes of lifo liquidation firms are highly correlated thus while univariate support for both the declining sales and declining earnings explanations of lifo liquidations could indicate that both explanations are correct it could also be the case that support for either explanation stems from the high correlation between sales changes and earnings changes our multivariate approach helps avoid such ambiguities in interpretation and supports two conclusions first

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

towards sustainable consumption economic modelling of mobility and heating for austria abstract the paper focuses on economic modelling and empirical analysis of sustainable structures in private consumption and strives to extend conventional economic consumption models the model analysis of sustainable consumption in the areas heating and transport for austria attempts to depart from traditional measurement of consumption in national accounts and economic consumption models the focus of the analysis is laid on consumer services derived from a combination of stocks e g building stock transport systems and flows mainly energy this approach intends to illustrate that a concentration on flows in consumption models lacks important aspects of sustainable consumption the economic analysis of sustainable consumption patterns aims to highlight the effects related to the substitution of flows by stocks in the consumption areas transport and heating e g improvements in thermal quality of buildings more energy efficient transport systems relevant too in this respect is the role that can be played by technological innovation improvements in energy efficiency of stocks the potential for specific incentives to promote new technologies two essential factors are crucial in the context of sustainable consumption the demand shifts concerning the consumer services desired and the composition of the stock flow mix necessary for the service provision

capital adequacy ratio regulations and accounting choices in commercial banks abstract this study examines a commercial bank manager s incentives to reduce regulatory costs imposed when the bank s capital adequacy ratio falls below its regulatory minimum it also tests the general political sensitivity hypothesis that a manager seeks to reduce political costs incurred when revenue is unusually large tests of adjustments to the loan loss provision loan charge offs and securities gains and losses attempt to control for exogenous economic conditions and previous investing decisions results are consistent with hypotheses associating accounting adjustments with capital adequacy ratio guidelines but fail to support the political sensitivity hypothesis

returns to scale adjustment costs and the optimal investment of the mining firm abstract this paper analyses the optimal investment programme of a competitive mining firm for two different technologies and capital adjustment costs in the first part the case of a variable proportions technology with decreasing returns to scale is studied and it is concluded that under the assumption of a constant mineral price a first stage in the exploitation period of the deposit will occur in which capital stock is increasing in the second part the optimal investment programme is determined when there are constant returns to scale and hotelling s rule governs the dynamics of the mineral price

theory and estimation of the household production function for wildlife recreation abstract the household production function is an intuitively appealing way to model man s interaction with nature this paper models the interaction between the household s behavior and publicly provided inputs into wildlife recreation the paper shows how to compute benefits assuming that the household production function is known the household production function approach collapses to the simple travel cost approach when households are unable to substitute their own inputs for publicly provided inputs in addition the paper demonstrates the conditions under which the parameters of cost and preference functions can be identified the conditions for identification are quite restrictive when several choices are endogenous

adjustment costs uncertainty and the theory of investment the case of non renewable natural resources abstract this paper examines the effects of mineral price and extraction cost uncertainty on the investment program of a competitive resource extracting industry that faces convex costs of adjustment the results show that depletion of mineral reserves will slow down if the marginal adjustment cost function is concave or linear whereas the effect will be ambiguous if the function is convex

income uncertainty and optimal redistribution 1 introduction redistribution policy under a utilitarian criterion aims to transfer dollars from one group in the population to another if the weighted utility gain to the recipients exceeds the utility cost to the donors under diminishing marginal utility of income part of any exogenous change in one group s income should be shared with the other group for example if taxpaying workers suffer a negative shock to their mean earnings then part of this utility shock should be spread to nonworkers in the form of lower transfer payments and vice versa for the case of a positive shock this article demonstrates the counterintuitive result that under reasonable preference representations a policymaker may respond optimally to a negative utility shock by redistributing income away from the harmed group thus exacerbating the group s utility loss in particular under risk aversion a mean preserving increase in the variance of income typically has an effect on well being analogous to a decrease in mean income 1 it may nevertheless be welfare enhancing to transfer income away from those suffering an increase in income uncertainty even though this policy compounds their welfare loss the main ideas can be demonstrated in a simple framework for illustration the analysis will focus on redistribution from taxpaying workers to nonworkers the central result is that a meanpreserving increase in earnings uncertainty among taxpayers can increase optimal transfer amounts to nonworkers increasing optimal income replacement rates even though the redistribution exacerbates the taxpayers utility loss from the increase in uncertainty 2 model footnote 1 many factors in the economy affect earnings uncertainty even conditional on being employed such as the form of compensation e

political cost incentives for managing the property liability insurer loss reserve this paper examines the effect of rate regulation on the management of the property liability insurer loss reserve the political cost hypothesis predicts that managers make accounting choices to reduce wealth transfers resulting from the regulatory process managers may under state reserves to justify lower rates to regulators alternatively managers may have an incentive to report loss inflating discretionary reserves to reduce the cost of regulatory rate suppression we find insurers over state reserves in the presence of stringent rate regulation investigating the impact along the conditional reserve error distribution we discover that a majority of the response occurs from under reserving firms under reserving less because of stringent rate regulation

labor supply flexibility and portfolio choice in a life cycle model abstract this paper examines the effect of the labor leisure choice on portfolio and consumption decisions over an individual s life cycle the model incorporates the fact that individuals may have considerable flexibility in varying their work effort including their choice of when to retire given this flexibility the individual simultaneously determines optimal levels of current consumption labor effort and an optimal financial investment strategy at each point in his life cycle we show that labor and investment choices are intimately related the ability to vary labor supply ex post induces the individual to assume greater risks in his investment portfolio ex ante

discretionary behavior with respect to allowances for loan losses and the behavior of security prices abstract the study examines the capital market pricing of discretionary and nondiscretionary components of a major accrual in the banking industry the allowance for loan losses the analysis employs a two stage approach in which the allowance account is first decomposed into estimates of its nondiscretionary and discretionary components the second stage evaluates the market s valuation of the estimates of the components evidence suggests that the capital market perceives the allowance to be comprised of two components a nondiscretionary component which is negatively priced and a discretionary component whose incremental pricing coefficient is positive

production and investment in natural resource industries there has been a recent tendency for economists to view natural resource scarcity as a diminishing threat to man s existence and his ability to produce an abundant supply of worldly goods see john v krutilla this change in view has emanated from the world s experience of the last few decades with technological development and the absence of any evidence that this rapid accumulation of technical knowledge will cease in some respects one might think that modern technology has removed the need for an economic theory of conservation temporal allocation of natural resources on the other hand conservation of natural resources can now be looked upon with less emotion since the dire consequences of too rapid exploitation are no longer a threat the question of conservation is thus a cold economic problem removed from many of its older value connotations there is indeed considerable effort taking place in the economics profession to fill this need for a quantitative economic theory of conservation however with one exception vernon smith focus has been limited to specific resources earlier works by lewis c gray and harold hotelling concerning the theory of the mine have recently been extended in numerous papers see r cummings and 0 burt richard l gordon anthony scott 1967 problems associated with petroleum production are considered in paul davidson and the fishery is considered in j a crutchfield and arnold zellner h scott gordon james quirk and vernon smith anthony scott 1955 and ralph turvey an extensive literature exists on the temporal allocation of groundwater two recent contributions are gardner brown and charles b mcguire and burt a logical problem has been encountered however in efforts to examine the optimum allocation of a natural resource over time without explicitly considering the rate of investment associated with resource use this difficulty stems from the long life of many capital items used in the process of exploiting the natural resource earlier studies have either tacitly or explicitly amortized costs of investment associated with resource use and proceeded as though all costs of production were essentially variable smith was the first to explicitly bring capital investment into a production model for natural resources and his work was followed by the authors where only exhaustible resources were considered more recently quirk and smith have introduced a dynamic model of the fishery in which capital investment is treated explicitly it seems then that there is a need for a comprehensive model for simultaneously optimizing the rate of resource use and investment in natural resource industries

using tax return data to simulate corporate marginal tax rates abstract we document that simulated corporate marginal tax rates based on financial statement data shevlin t 1990 estimating corporate marginal tax rates with asymmetric tax treatment of gains and losses the journal of the american taxation association 11 51 67 graham j 1996a debt and the marginal tax rate journal of financial economics 41 41 73 are highly correlated with simulated rates based on corporate tax return data we provide algorithms that can be used to estimate the book or tax simulated rates when they are not available we find that the simulated book marginal tax rate does a better job of explaining financial statement debt ratios than does the analogous tax return variable and discuss how the book simulated rate is likely to be an appropriate measure in settings with global long term considerations

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

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

real effects of accounting rules evidence from multinational firms investment location and profit repatriation decisions we analyze survey responses from nearly 600 tax executives to better understand corporate decisions about real investment location and profit repatriation our evidence indicates that avoiding financial accounting income tax expense is as important as avoiding cash income taxes when corporations decide where to locate operations and whether to repatriate foreign earnings this result is important in light of the recent research about whether financial accounting affects investment and in light of the decades of research on foreign investment that examines the role of cash income taxes but heretofore has not investigated the importance of financial reporting effects our analysis suggests that financial reporting is an important factor to be considered in the policy debates focused on bringing investment to the united states
