do greens drive hummers or hybrids environmental ideology as a determinant of consumer choice this paper uses several california data sets to test for differences in consumption patterns between greens and browns a person s environmentalism is rarely observed in consumer data sets in california a community s share of green party registered voters is a viable proxy for community environmentalism environmentalists are more likely to commute by public transit purchase hybrid vehicles and consume less gasoline than non environmentalists

assessing income population and technology impacts on co2 emissions in canada where s the ekc abstract this study investigates the macroeconomic forces underlying carbon dioxide co2 emissions from fossil fuel use in canada in keeping with the relevant literature on environmental degradation three forces are expected to influence co2 emissions gross domestic product per capita gdp capita population and technological change while previous work has employed reduced form models that allow for non linear relationships between co2 and gdp capita it has been common practice to assume linear relationships between co2 and the latter two variables this study tests a more flexible model using a five region panel data set in canada over the period 1970 2000 findings indicate that gdp capita is unrelated to co2 that an inverted u shaped relationship exists with population and that a u shaped relationship exists with technology thus technological and population changes are supported over the commonly hypothesized environmental kuznets curve an inverted u shaped relationship between gdp capita and environmental degradation for affecting co2 emissions from fossil fuel use in canada

intergenerational equity the capital environment trade off abstract this paper examines the trade off between capital accumulation and environmental quality that determines an intergenerationally equitable program according to the rawls maximin criterion this trade off is explored by an analysis of regular maximin programs in the framework developed by brock this results in a constant utility path supported by competitive prices with government imposed effluent charges and environmental rentals sufficient conditions for a regular maximin path to satisfy a hartwick rule in deciding on the combination of capital and environmental quality left to future generations are given

pollution abatement and balanced growth the analysis of endogenous growth models with pollution often concentrates on steady state trajectories under the assumption that the steady state is in some sense stable in the present note we provide examples showing that this issue should be dealt with carefully we use the rebelo ak model augmented with a stock of pollutants causing a negative externality it is found that optimal growth is not necessarily balanced contrary to the outcome of the standard rebelo model moreover the existence of the externality may affect long run optimal growth rates

the information content of security prices a second look abstract beaver lambert and morse 1980 employ a regression of percentage change in prices on percentage change in earnings in which data are grouped by the dependent variable reverse regression offers a more intuitive and direct way to assess the information content of security prices the objective of beaver et al while grouping is asymptotically equivalent reverse regression is a more efficient way of examining the incremental explanatory power of lagged values of percentage change in price with respect to accounting earnings

discussion of international differences in the timeliness conservatism and classification of earnings pope and walker examine differences in the timeliness and conservatism of u s and u k reported earnings they conclude that the u s accounting regime appears significantly more conservative than the u k regime when comparing earnings before extraordinary items however when comparing bottom line earnings they find the opposite the paper contributes to research on international differences in accounting and their causes and consequences the conference discussion focused on accounting differences between the united kingdom and the united states the assumptions underlying the analyses in the paper and the interpretation of the results in the following sections i discuss the authors research design choices examining in turn the motivation research agenda and specification issues

household production and environmental kuznets curves examining the desirability and feasibility of substitution this paper provides a theoretical explanation for the widely debatedempirical finding of environmental kuznets curves i e u shaped relationships between per capita income and indicators of environmentalquality we present a household production model in which the degradationof environmental quality is a by product of household activities householdscan not directly purchase environmental quality but can reduce degradation by substituting more expensive cleaner inputs to production for less costlydirty inputs if environmental quality is a normal good one expectssubstitution towards the less polluting inputs so that increases in incomewill increase the quality of the environment it is shown that this onlyholds for middle income households poorer households spend all income on dirty inputs when they buy more as income rises the pollution also rises they do not want to substitute as this would reduce consumption ofnon environmental services for environmental amenities that are alreadyabundant thus as income rises from low to middle levels a u shape can result yet an n shape might eventually result as richer households spend all income on clean inputs further substitution possibilities are exhausted thus as income rises again pollution rises and environmental quality falls

information in prices about future earnings abstract stock return over a period reflects the market s revision in expectation of future earnings accounting earnings over the same period however have limited ability to reflect such revised expectations therefore returns anticipate earnings changes and the earnings response coefficient from a regression of returns on contemporaneous earnings changes is biased toward zero we reduce this bias by including leading period returns in price earnings regressions the resulting estimated earnings response coefficient magnitudes suggest that the capital market on average views earnings changes to be largely permanent this is consistent with the random walk time series property of annual earnings

an analysis of the relation between the stewardship and valuation roles of earnings in this paper we seek a deeper understanding of how accounting information is used for valuation and incentive contracting purposes we explore linkages between weights on earnings in compensation contracts and in stock price formation a distinction between the valuation and incentive contracting roles of earnings in paul 1992 produces the null hypothesis that valuation earnings coefficients vecs and compensation earnings coefficients cecs are unrelated our empirical analyses of the relations between earnings and both stock prices and executive compensation data at the firm and industry levels over the period 1971 2000 rejects paul s 1992 hypothesis of no relation we also document an increasing weight over time on other public performance information captured by stock returns in the determination of cash compensation specifically we find that the incentive coefficient on returns is significantly higher in the second of two equal sample subperiods relative to the incentive coefficient on earnings

is trade good or bad for the environment sorting out the causality we seek to contribute to the debate over globalization and the environment by asking what is the effect of trade on a country s environment for a given level of gdp we take specific account of the endogeneity of trade using exogenous geographic determinants of trade as instrumental variables we find that trade tends to reduce three measures of air pollution statistical significance is high for concentrations of so2 moderate for no2 and lacking for particulate matter although results for other environmental measures are not as encouraging there is little evidence that trade has a detrimental effect on the environment

a household level environmental kuznets curve some recent evidence on transport emissions and income this paper uses detailed survey data to show no evidence of an environmental kuznets curve ekc for household transport emissions the evidence shows that richer households still do not choose to internalize the social cost of polluting by vehicle emissions

anonymity monotonicity and limited neutrality selecting a single alternative from a binary agenda abstract anonymity and neutrality conflict if the number of individuals is even and a single alternative is selected limited neutrality anonymity and monotonicity imply majority rule when the agenda is a two element set

the impact of economic growth on co2 emissions in azerbaijan abstract this paper investigates the relationship between the economic growth and co2 emissions in azerbaijan a cointegration analysis is conducted over the period 1992 2013 for getting more robust results johansen ardlbt dols fmols and ccr methods are employed to explore cointegration and estimate long run coefficients we use cubic quadratic and linear specifications and conclude that the last one is an adequate representation for the impact of the economic growth on co2 emissions in azerbaijan the results from the different cointegration methods are consistent with each other and show that the economic growth has a positive and statistically significant impact on the emissions in the long run implying that the ekc hypothesis does not hold for azerbaijan the income elasticity of co2 emissions using different methods is found to be between 0 7 and 0 8 moreover we find that any short run imbalance can be adjusted towards the long run equilibrium path within less than one year the paper concludes that measures to increase energy efficiency carbon pricing instruments in production and international domestic trade activities and nationwide social awareness programs to instruct about the negative consequences of pollution can be considered as relevant environmental policies aimed at reducing carbon emissions

neoclassical growth the j curve for abatement and the inverted u curve for pollution abstract this paper reexamines the neoclassical environmental growth model of forster to gain insights into the dynamic relationships among pollution abatement effort and economic development whereas the model has heretofore been used to examine steady state levels of capital consumption and environmental quality it also provides a theoretical basis for recent empirical research on j curves for abatement effort and inverted u curves for pollution

multiple equilibria in a stochastic implementation of dice with abrupt climate change abstract integrated assessment modeling of global climate change has focused primarily on gradually occurring changes in the climate system however atmospheric and earth scientists have become increasingly concerned that the climate system may be subject to abrupt discontinuous changes on short time scales and that anthropogenic greenhouse gas emissions could trigger such shifts incorporating this type of climate dynamics into economic or integrated assessment models can result in model non convexity and multiple equilibria and thus complicate policy analysis relative to models with unique globally optimal policies using a version of the nordhaus dice model amended in previous research by keller et al 2004 keller klaus benjamin m bolker david f bradford 2004 uncertain climate thresholds and optimal economic growth journal of environmental economics and management 48 1 723 741 in conjunction with a stochastic global optimization algorithm we generate level sets of solutions which helps identify multiple equilibria resulting from the potential abrupt cessation of the north atlantic thermohaline circulation we discuss the implications of this model geometry for formulating greenhouse gas abatement policy under uncertainty and suggest that this general approach may be useful for addressing a wide range of model non convexities including those related to endogenous technological change

economic growth pollution and renewable resources abstract this paper first analyzes a model of economic growth with stock pollution allowing smooth substitution between emissions and reproducible capital when emissions are optimally controlled the steady state consumption is lower than without pollution control but the optimal steady state equilibrium may not exist if the marginal productivity of capital is bounded the steady state is shown to be a local saddle point independent of the rate of discount if pollution is not controlled a competitive economy moves along a stable growth path toward a too heavily polluted steady state next a growth model in which pollution affects the growth of renewable resources is presented the conditions for the existence and saddle point property of the steady state are given and the consequences of nonoptimal externality taxes are discussed when renewable resources are included higher than optimal pollution may decrease steady state consumption contrary to the case where renewable resources are ignored

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

the information content of earnings and prices a simultaneous equations approach abstract the price earnings relation can be characterized as a system of simultaneous equations earnings and prices can behave as if they are both endogenously determined because they are jointly affected by information that is difficult to specify explicitly specification tests provide evidence that both earnings changes and price changes are endogenous the price and earnings coefficients increase from ols to joint estimation and under a restrictive set of assumptions provide increasingly similar estimates of the permanent component of earnings the evidence is consistent with the contention that a portion of the single equation bias can be mitigated via joint estimation

market assessment of industry and firm earnings information abstract this study examines the timing of security returns associated with industry wide earnings and firm specific earnings we predict and find that returns associated with differences in performance across industries begin and end earlier than returns associated with differences in firm specific performance within industries to earn abnormal profits a trading strategy based on forecasts of future earnings would require earlier predictions of industry wide earnings than of firm specific earnings

estimating earnings response coefficients pooled versus firm specific models abstract short window earnings response coefficients estimated from pooled time series cross sectional regressions are systematically smaller than corresponding averages of firm specific coefficients estimated from time series regressions the cause is a negative relation between firm specific earnings response coefficients and unexpected earnings variances if the hypotheses of equality of firm specific coefficients and equality of firm specific unexpected earnings variances are rejected firm specific estimation should be used instead of pooled estimation using pooled estimation may lead to incorrect inferences about the magnitude of estimated coefficients and or incorrect inferences about differences in coefficient behavior between groups of firms

parallel axiomatizations of majority and unanimity the relative majority rule and the unanimity rule are characterized for the case in which there are only two alternatives the main axioms are motivated by a principle of binary representativeness the aggregation of the preferences of n voters is the result of splitting the n voters into two groups aggregating the preferences of the voters of each group selecting for each group a representative that adopts the preference of the group and finally aggregating the preferences of the two representatives the two characterizations are shown to differ from each other in just one axiom expressing strategyproofness unanimity or group strategyproofness majority

permanent versus transitory components of annual earnings and estimation error in earnings response coefficients abstract previous research has generally estimated unexpected earnings as the change relative to the previous year assuming that shocks to annual earnings are purely permanent in the presence of transitory components of annual earnings we predict that using earnings changes as a proxy for unexpected earnings causes earnings response coefficients to be understated and the estimation error to be negatively cross sectionally correlated with persistence the negative correlation causes the association between earnings response coefficients and persistence to be overstated we use the ima 1 1 model to capture transitory components of annual earnings and obtain results that are consistent with our predictions

corporate capital expenditure decisions and the market value of the firm abstract this paper is an event time study of the common stock prices of a sample of 658 corporations around the dates on which they publicly announced their future capital expenditure plans for industrial firms announcements of increases decreases in planned capital expenditures are associated with significant positive negative excess stock returns for public utility firm neither increases nor decreases in planned capital expenditures are associated with significant excess stock returns we interpret the evidence as being consistent with the hypothesis that managers seek to maximize the market value of the firm in making their corporate capital expenditure decisions

carbon capture and storage and transboundary pollution a differential game approach abstract we study the strategic behavior of two countries facing transboundary co2 pollution under a differential game setting in our model the reduction of co2 concentration occurs through the carbon capture and storage process rather than through the adoption of cleaner technologies furthermore we first provide the explicit short run dynamics for this dynamic game with symmetric open loop and a special markovian nash strategy then we compare these strategies at the games steady states and along some balanced growth paths our results show that if the initial level of co2 is relatively high state dependent emissions reductions can lead to higher overall environmental quality hence feedback strategy leads to less social waste

real investment implications of employee stock option exercises this paper examines a real cost of awarding employee stock options based on the observation that managers are extremely concerned about earnings per share dilution in equity related compensation we predict and find that firms experiencing significant employee stock option eso exercises shift resources away from real investments towards the repurchase of their own stocks we further find weak evidence of a decline in subsequent firm performance as measured by return on assets for several years following the cut in discretionary investments as a result of stock option exercises though this result is sensitive to the metric used to measure performance collectively our findings indicate that eso exercises potentially impose a real cost on the firm in terms of foregone investment opportunities

economic development and the energy intensity of human well being evidence from the gcc countries abstract this paper empirically investigates the effect of economic development on the energy intensity of human well being eiwb in the gulf cooperation council gcc during the period 1995 2012 we employ a time series cross sectional prais winsten regression model with panel corrected standard errors pcse we conclude that economic development has had a significant positive impact on eiwb during the period 1995 2012 the results indicate that the stress on the environment had increased in a noticeable manner from 1995 until 2006 however over the period 2007 2012 the stress went back to the level observed in 1995 this observation is unfortunate from the perspective sustainable economics

the association between accounting earnings and security returns for large and small firms abstract the differential information hypothesis advanced by atiase 1980 states that information production and dissemination by private parties for the purpose of identifying mispriced securities is an increasing function of firm size this study examines two corollaries of that hypothesis first security prices of large firms anticipate accounting earnings earlier than security prices of small firms second for a given level of unexpected earnings the cumulative abnormal returns of small firms exceed those of large firms the results are generally consistent with atiase s hypothesis

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 valuation of the foreign income of us multinational firms a growth opportunities perspective we demonstrate the value relevance of foreign earnings for us multinational firms by examining the associations between annual abnormal stock performance and changes in firms domestic and foreign incomes for 2570 tirm year observations between 1985 and 1993 both foreign and domestic earnings changes have significant positive associations with annual excess return measures however the association coefficient on foreign income is significantly larger than the association coefficient on domestic income we demonstrate this larger association coefficient for foreign income is consistent with differences in growth opportunities between domestic and foreign operations

internal corporate restructuring abstract firms that alter their divisional configurations on average increase shareholder wealth gains appear to come from information about investment opportunities and increases in efficiency performance before the restructurings suggests poorly organized firms are motivated by market pressures to change their organizations change also occurs in healthy firms as part of the growth process restructuring often occurs where there is no evidence of takeover threats while stock prices increase around the restructurings there is a contemporaneous decline in earnings due to increased expenses these findings appear inconsistent with the contention that the market pressures managers into focusing on short run earnings

another characterization of the majority rule abstract given any finite society confronting two alternatives may econometrica 20 1995 680 characterizes the majority rule in terms of anonymity neutrality and positive responsiveness this final condition is usually criticized to be too strong thus we drop it and give a similar characterization in terms of anonymity neutrality pareto optimality and a condition we call weak path independence

earnings as an explanatory variable for returns in this paper we investigate whether the level of earnings divided by price at the beginning of the stock return period is relevant for evaluating earnings returns associations the primary model motivating this research relies on the idea that book value owners equity and market value are both stock variables indicating the wealth of the firm s equity holders the related flow variables after adjusting for dividends are respectively earnings divided by price at the beginning of the return period a p 1 and market returns it then follows that earnings divided by beginning of period price should be associated with stock returns although models based on a relation between market value and book value are used occasionally in the accounting research literature see for example landsman 1986 harris and ohlson 1987 and barth

the relation between the return interval and betas abstract the size effect is sensitive to the length of the return interval used in estimating betas beta changes with the return interval because an asset s covariance with the market and the market s variance do not change proportionately as the return interval is changed we document beta sensitivity to the return interval evidence from cross sectional regressions of returns on monthly and annual betas is inconsistent with beta changes stemming only from the higher standard errors of the longer interval betas we provide evidence that the size effect becomes statistically insignificant when risk is measured by betas estimated using annual returns

a household level environmental kuznets curve abstract richer households may create more vehicle emissions because they own more vehicles and drive more poorer households may pollute more because they use high polluting vintages and maintain them less well this paper uses 1993 california vehicle microdata to show that there is a kuznets u shaped hydrocarbon emissions relation

the integration of natural capital into development policies in response to the united nations sustainable development goals there has been a rising awareness of the need to address simultaneously the preservation of natural capital stocks and poverty alleviation at multiple scales focusing on tropical forest rich developing countries the article overviews the extent to which natural capital considerations are integrated into existing development policies and interventions the review finds that the explicit consideration of natural resources is left out of many commonly applied development interventions leading to suboptimal and unsustainable outcomes the interventions that do tackle both development and conservation goals are often not coordinated and are implemented at a site by site basis without providing the socially efficient levels of natural capital stocks or ensuring the long term sustainability of the development and conservation impacts bringing in perspectives from development economics environmental economics and applied conservation this article makes the case for a better integration of development and conservation goals in interventions in developing countries and outlines the emerging frontiers for research and policy

output emissions and technology some thoughts abstract the principal goal of this article is to identify the implications of a binding emission constraint on a firm s optimal capital labor ratio and to determine whether it is appropriate to write a firm s production function as an increasing function of its emissions alone i find that even though a firm s supply curve may be written as a positive function of its emissions it is not appropriate to write the production technology as an increasing function of only its emissions except under special circumstances

are there increasing returns to pollution abatement empirical analytics of the environmental kuznets curve in pesticides abstract according to the environmental kuznets curve ekc hypothesis economic growth and the reduction of environmental degradation are compatible goals an inverted u shaped relationship between economic performance and environmental pollution suggests that empirically an economy is associated with smaller levels of pollution after some threshold income point one potential explanation for the empirical evidence of an ekc is increasing returns to pollution abatement where the abatement efficiency rises with an increase in the scale of abatement doubling the clean up efforts more than doubles the abatement of pollution as this efficiency gain makes abatement less expensive pollution might fall as more abatement is undertaken this study tests the hypothesis that there are increasing returns to abating pollution empirical evidence on environmental risks in the us agricultural sector since 1970 support the existence of increasing returns in addition i estimate the productivity of pollution abatement using refined empirical productivity measurement methods and explicitly control the level of technology the results show the importance of including an environmental productivity variable in the ekc framework

are there limits to growth a simple theoretical model of pollution is developed that generates an inverted u shape relationship between per capita income and environmental quality this model is then used to study long run growth the same inverted u shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital implementation is also studied tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

firm size and the information content of prices with respect to earnings abstract beaver lambert and morse 1980 suggest that prices may be useful in forecasting future earnings we explore the information content of prices with respect to earnings by focusing on firm size and its relation to the predictive accuracy of price based earnings forecasts firm size proxies for the amount of information and for the number of traders and professional analysts processing the available information about an enterprise our empirical results are consistent with the hypothesis that price based earnings will outperform univariate time series forecasts by a greater margin for larger firms than for smaller firms

sustainable growth and the environmental kuznets curve abstract this paper develops an endogenous growth model with pollution and both human and physical capital human capital is produced cleanly and physical capital can be used for pollution control economic growth is sustainable in the long run it is optimal for human capital to grow more rapidly than physical capital output and consumption while pollution declines for realistic parameter values our results differ sharply from stokey s result for an ak technology that sustained economic growth is not optimal the model can generate an environmental kuznets curve a pollution tax or a voucher system can implement the pareto efficiency solution

technical progress structural change and the environmental kuznets curve abstract the paper shows that under reasonable assumptions about technical progress a positive sustainable growth rate fails to exist the argument is that a growing part of income has to be spent for continuing technical progress in order to compensate the pollution effects of growth hence in the long run either the sustainability condition will be violated or the growth rate must decline to zero furthermore in finite time the level of wealth will decrease despite growing income and a constant pollution level thus further growth is no longer reasonable similar arguments also hold for the environmental effects of structural change favoring less pollution intensive economic activities an evolutionary change of goods and production technology may shift the limits of growth and is hence a prerequisite for a long run ekc

fair value disclosures by bank holding companies abstract this paper examines the value relevance of fair value data disclosed under sfas 107 by banks for 1992 and 1993 collectively the evidence suggests differences between fair and book values of financial instruments are associated with market to book ratios however fair value disclosures for financial instruments other than securities are value relevant only in limited settings in addition only in 1992 are fair value variables associated with market to book ratios after incorporating existing historical cost information further analysis suggests the weaker 1993 results are not necessarily due to increased measurement error in fair value numbers

a complete characterization of majority rules abstract given finite society and any set of alternatives we characterize the majority rule and weak majority rule in terms of anonymity iia neutrality and positively responsive property

majority selection of one alternative from a binary agenda abstract there are two feasible alternatives we impose a weak version of anonymity on an arbitrary social choice function which selects a single alternative at each profile it implies majority rule in the presence of neutrality and monotonicity

corruption and the environmental kuznets curve empirical evidence for sulfur abstract we investigate how corruption influences the income level at the turning point of the relationship between sulfur emissions and income using a wide cross national panel of countries at different levels of development and with different degrees of corruption our results support the environmental kuznets curve hypothesis for sulfur we find evidence that the higher the country s degree of corruption the higher the per capita income at the turning point suggesting different income pollution paths across countries due to corruption we build upon a new specification for the ekc developed by bradford et al 2005 that avoids using nonlinear transformations of potentially nonstationary regressors in panel estimation also we account for the indirect impact of corruption on emissions through its impact on per capita income our main findings remain unchanged when we investigate additional heterogeneity allowing for different income slopes across richer and poorer countries

the ecological footprint of poverty alleviation evidence from mexico s oportunidades program abstract we study the consequences of poverty alleviation programs for environmental degradation we exploit the community level eligibility discontinuity for a conditional cash transfer program in mexico to identify the impacts of income increases on deforestation and use the program s initial randomized rollout to explore household responses we find that additional income raises consumption of land intensive goods and increases deforestation the observed production response and deforestation increase are larger in communities with poor road infrastructure this suggests that better access to markets disperses environmental harm and that the full effects of poverty alleviation on the environment can be observed only where poor infrastructure localizes them

single profile of preferences with variable societies a characterization of simple majority rule abstract we study simple majority rule for a fixed profile of individuals preferences and a variable society four properties each linking decisions by a group to decisions by its various subgroups are introduced and are used for characterizing simple majority rule

towards an integrated framework for development and environment policy the dynamics of environmental kuznets curves abstract environmental kuznets curves ekcs have recently received considerable attention in development and environment policy but little is known on how the interaction between ecological and economic factors may result in an ekc or other qualitatively different outcomes we introduce a restricted class of vector valued differential equations for representing the evolution of socioeconomic and environmental variables which influence or are influenced by the process of economic development our model includes not only the complete path of each variable over time but also the highly critical interactions among multiple variables we demonstrate analytically and numerically that among a multiplicity of possible outcomes an inverted u pattern can only be obtained under specific circumstances and requires attention to the multiple factors which form the economic environmental system rather than a single dominant one

do baths muddy the waters or clear the air we examine the information environments of firms following large non recurring charges baths we test competing hypotheses about the consequences of a bath a bath either improves the information environment the transparency hypothesis or degrades it the opacity hypothesis difference in differences analysis suggests that after a bath 1 earnings become smoother 2 firm level information asymmetry decreases and 3 stock returns become more responsive to unexpected earnings we interpret these findings as supportive of the transparency hypothesis we also document that the relative improvement in the information environment is greater for baths that are not voluntary consistent with managerial obfuscation prior to the bath

a review of the age of sustainable development by jeffrey sachs how does economic science inform the study of sustainable development in his new book jeffrey d sachs analyzes the challenges of achieving economic growth while protecting the environment and achieving an equitable distribution of resources this review presents an overview of this ambitious book with special emphasis on the role of the objectives of local and national leaders and their incentives to pursue the sustainability agenda given the huge migration to cities now playing out in the developing world special attention is paid to the role of urbanization as a cause of sustainability opportunities and challenges

models as usual for unusual risks on the value of catastrophic climate change we study the role of alternative intertemporal preference representations in a model of economic growth stock pollutant and endogenous risk of catastrophic collapse we contrast the traditional discounted utility model which assumes risk neutrality with respect to intertemporal utility with a multiplicative choice model that displays risk aversion in that dimension first we show that both representations of preferences can rationalize the same business as usual economy for a given interest rate and no pollution externality second once we introduce a collapse risk whose hazard rate is a function of the pollution stock multiplicative preferences recommend a much more stringent policy response an illustration in the context of climate change indicates that switching to the multiplicative preference representation has a similar effect in terms of policy recommendations as scaling up the schedule of the hazard rate by a factor of 100

cross sectional dependence and problems in inference in market based accounting research this paper provides a framework and some empirical evidence to evaluate the seriousness of problems in inference that arise in stockreturn based studies when the data are cross sectionally dependent the study is motivated on the grounds that statistical procedures designed to address such problems are often infeasible and even when they can be implemented they sometimes introduce other more serious difficulties thus researchers have frequently adopted an approach that ignores the cross sectional dependence e g ordinary least squares ols the objective of this paper is to help identify the contexts in which ignoring the dependence would lead to serious misstatement of significance levels cross sectional dependence in stock returns data is likely to exist when at least some of the returns are sampled from common time periods this would be the case in all studies of the reaction of stock prices to a

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

climate change and uneven development in this paper using a theoretical model with endogenous capital depreciation we study the effects of climate change and adaptation on long run development we show that climate change affects economic growth depending on climate exposure and adaptation efficiency which are asymmetric between different countries poor countries are likely to be hurt more because of the negative effects of climate change on the rate of depreciation of the assets that represent the engine of growth these asymmetries generally induce growth deficits and unsustainability traps in less developed economies

complete markets informed trading and equity option introductions this paper proposes and tests a new hypothesis concerning the price impact of option introductions on the underlying asset we argue that the leverage properties of options induce a higher level of informed trading in the aggregate market underlying plus derivative resulting in excess listing day price movements in the newly optioned equity using an alternative dataset our results suggest that this may be an explanation for the observed positive than negative excess listing day returns of us optioned stocks over the past thirty years

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

accounting earnings and top executive compensation abstract this paper investigates the role of accounting earnings in top executive compensation contracts it provides evidence in support of the hypothesis that earnings based incentives help shield executives from market wide factors in stock prices the paper demonstrates that earnings reflect firm specific changes in value but are less sensitive to market wide movements in equity values as a result the inclusion of earnings based performance measures in executive compensation contracts helps shield executives from fluctuations in firm value that are beyond their control the hypothesis is shown to explain cross sectional variation in the use of earnings based incentives

nash implementation of the majority rule abstract given a society confronting two alternatives we show that the absolute majority rule is the minimal nash implementable extension of the relative majority rule

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

the effect of accounting procedure changes on ceos cash salary and bonus compensation abstract this paper examines the effect of accounting procedure changes on cash salary and bonus compensation to ceos we estimate whether there is an adjustment to the statistical relation between compensation and corporate earnings following changes that lower earnings fifo to lifo inventory valuation and that raise earnings accelerated to straight line depreciation the results indicate that 1 subsequent to these changes salary and bonus payments are based on reported earnings rather than earnings under the original accounting method and 2 the potential compensation effect of the changes is small compared to the effect of economy or industry wide changes in compensation

international differences in the timeliness conservatism and classification of earnings in this paper we analyze differences in the timeliness of income recognition between the u s and u k gaap financial reporting regimes building on previous work in the area we focus on the links between current reported earnings and current and past changes in market value in the light of basu 1997 we present a formal model in which the response of reported earnings to changes in market value varies according to whether the value change is good news or bad this model yields a number of insights with regard to the definition and measurement of earnings conservatism we also report evidence indicating that controlling for cross jurisdictional classification differences affects comparisons of earnings timeliness and earnings conservatism specifically we find that apparent differences in conservatism between the u s and u k accounting regimes are sensitive to the inclusion or exclusion of extraordinary items in u k accounting earnings recent research documents significant variation in the information content of earnings across international gaap regimes e g alford et al tlancaster university tuniversity of manchester the research support of the eco

intra industry trade in intermediate products pollution and internationally increasing returns this paper examines the relationship between intra industry trade in intermediate products pollution and increasing returns we develop a two country model in which production occurs in two stages final and intermediate good production intermediate goods are produced under monopolistic competition and final good production exhibits increasing returns with respect to the number of varieties of intermediates pollution occurs in the production of the final good when polluting intermediates are used we analyze the effects of international trade in intermediate products on pollution output and welfare under an endogenous tax scenario and with two types of pollution functions the results show that because of increasing returns international trade either leads to lower total pollution in each country or lower pollution per unit of output in at least one country in addition intra industry trade causes countries to import the environmental quality of their trading partners

a tradable permit system in an intertemporal economy it is known that in an intertemporal competitive economy a tradable permit system may not achieve efficiency without setting appropriate permit interest rates i e rewards for holding permits to find the rates however we need to know in advance the path of efficient permit prices which is difficult to obtain this study intends to solve this problem in two ways first we analyze a special case in which the permit interest rates are given by a simple rule for example if the marginal abatement cost of pollution emission is constant then the appropriate rate is to equal the monetary interest rate as is the case for global warming if the damage is caused in the future far beyond the planning period of the environmental program the appropriate rate coincides with the marginal self recovery of environmental stock under certain conditions as a second approach we propose a tradable permit system with a permit bank as a mechanism by which the permit interest rates are generated endogenously without governmental intervention other than the issuance of permits however we also show that this approach raises the problem of indeterminacy of the equilibrium

a tale of two elasticities a general theoretical framework for the environmental kuznets curve analysis abstract we show that a variety of seemingly diverse concepts used to theoretically explaining the ekc have a common origin in two key preference and production elasticities we also prove that they jointly correspond to a unique underlying preference technology theoretical framework

voting for pollution policy the importance of income inequality and openness to trade abstract this paper analyzes how openness and the distribution of factor ownership interact to determine individual and aggregate demand for pollution policy analysis of voter preferences in autarky shows that an increased stake in either the dirty or the clean industry can induce an individual voter to prefer stricter environmental policy similarly the paper shows that poorer voters may be the greener voters within an electorate the model also reveals that the incidence of pollution policy depends upon a country s trade regime with consequences for the direction in which income inequality influences aggregate demand for pollution policy

capital market effects of u s canada gaap differences canadian firms that list securities on u s stock exchanges are generally required to provide a reconciliation of reported income measured using canadian generally accepted accounting principles gaap to reported earnings measured using u s gaap this paper examines both the magnitudes and the information content of the reported reconciliations between canadiangaap income and u s gaap income two recent studies of cross country gaap differences do not address u s canada differences because of perceived similarities between gaap in the two countries amir harris and venuti 1993 and mcqueen 1993 if u s canada gaap differences are in fact unimportant then no further examination is warranted professional bodies however are

a characterization of status quo rules in the binary social choice model abstract this paper characterizes status quo rules in the binary social choice environment we consider the full preference domain which allows for indifference we show that status quo rules are the only rules that satisfy ontoness strategy proofness and a solidarity property the solidarity property that we consider positively correlates the welfare of a voter to rest of the voters in case of her improvement it is independent from the usual solidarity axiom of welfare dominance under preference replacement used in the literature

plant closing decisions and the market value of the firm abstract we investigate the underlying causes and the announcement effects of plant closings the closing in our sample do not appear related to takeover activity instead they appear motivated by declining firm profitability firms announcing closings have lower earnings than market or industry medians earnings typically improve slightly after the announcement we find a negative stock market reaction to plant closing announcements

econometrics of the basu asymmetric timeliness coefficient and accounting conservatism a substantial literature investigates conditional conservatism defined as asymmetric accounting recognition of economic shocks news and how it depends on various market political and institutional variables studies typically assume the basu 1997 asymmetric timeliness coefficient the incremental slope on negative returns in a piecewise linear regression of accounting income on stock returns is a valid conditional conservatism measure we analyze the measure s validity in the context of a model with accounting income incorporating different types of information with different lags and with noise we demonstrate that the asymmetric timeliness coefficient varies with firm characteristics affecting their information environments such as the length of the firm s operating and investment cycles and its degree of diversification we particularly examine one characteristic the extent to which unbooked information such as revised expectations about rents and growth options is independent of other information and discuss the conditions under which a proxy for this characteristic is the market to book ratio we also conclude that much criticism of the basu regression misconstrues researchers objectives

status concern and the exploitation of common pool renewable resources we examine the impact of social status concern in a common pool renewable resource oligopoly a small number of players share access to a common pool resource and sell their production in a common market where they are oligopolists we depart from the mainstream literature on common pool resource oligopolies by considering that each player cares about her social status we allow for two channels to impact a player s welfare harvest and profits under the first channel a player has a bump in her utility when her harvest is larger than the average harvest of the rest of the players in this case we show that the presence of this channel exacerbates the tragedy of the commons under the second channel a player enjoys a bump in her utility if she manages to earn more profits than the average profits of the other players in this case we show that social status concern may temporarily alleviate the tragedy of the commons it results in a decrease of extraction over an interval of stock sizes

preferences technology and the environment understanding the environmental kuznets curve hypothesis we derive a simple expression for the income pollution path using the standard static model of the environmental kuznets curve ekc this expression makes it straightforward to identify the general characteristics of utility and pollution functions that lead to such a curve we show that suitable preferences can always lead to an ekc while there is no technology that yields an ekc for all types of preferences and we derive a sufficient condition for technology that leads to an ekc for almost all types of preferences our results hold for a model with multiple goods with different pollution intensities and for a production economy with nonconstant relative price of consumption and environmental effort we derive our results without assuming specific functional forms and we encompass several other models as special cases
