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

the role of training in experimental auctions in this paper we examine the role of providing extensive training to subjects in the context of experimental auctions we conducted an experiment where we auctioned several lotteries with varying payoffs one group of subjects was extensively trained while another group of subjects was only minimally trained we find that subjects in the extensive training treatment were submitting bids significantly higher than subjects in the minimal training treatment suggesting that subjects without proper training may underreport their wtp

occupational choice and the process of development this paper models economic development as a process of institutional transformation by focusing on the interplay between agents occupational decisions and the distribution of wealth because of capital market imperfections poor agents choose working for a wage over self employment and wealthy agents become entrepreneurs who monitor workers only with sufficient inequality however will there be employment contracts otherwise there is either subsistence or self employment thus in static equilibrium the occupational structure depends on distribution since the latter is itself endogenous we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long run effects in one case the economy develops either widespread cottage industry self employment or factory production employment contracts depending on the initial distribution in the other example it develops into prosperity or stagnation

do practice rounds affect experimental auction results researchers use practice rounds to familiarize participants with experimental auction mechanisms we find a positive correlation between practice bids and bids submitted in later rounds we consider three explanations for this correlation a behavioral anchoring effect a tendency for some auction participants to be more free spending and misconception of the experimental auction s demand revealing qualities

the economics of poverty traps and persistent poverty an asset based approach abstract longitudinal data on household living standards open the way to a deeper analysis of the nature and extent of poverty while a number of studies have exploited this type of data to distinguish transitory from more chronic forms of income or expenditure poverty this paper develops an asset based approach to poverty analysis that makes it possible to distinguish deep rooted persistent structural poverty from poverty that passes naturally with time due to systemic growth processes drawing on the economic theory of poverty traps and bifurcated accumulation strategies this paper briefly discusses some feasible estimation strategies for empirically identifying poverty traps and long term persistent structural poverty as well as relevant extensions of the popular foster greer thorbecke class of poverty measures the paper closes with reflections on how asset based poverty can be used to underwrite the design of persistent poverty reduction strategies

capital is back wealth income ratios in rich countries 1700 2010 how do aggregate wealth to income ratios evolve in the long run and why we address this question using 1970 2010 national balance sheets recently compiled in the top eight developed economies for the united states united kingdom germany and france we are able to extend our analysis as far back as 1700 we find in every country a gradual rise of wealth income ratios in recent decades from about 200 300 in 1970 to 400 600 in 2010 in effect today s ratios appear to be returning to the high values observed in europe in the eighteenth and nineteenth centuries 600 700 this can be explained by a long run asset price recovery itself driven by changes in capital policies since the world wars and by the slowdown of productivity and population growth in line with the s g harrod domar solow formula that is for a given net saving

welfare dynamics in rural kenya and madagascar this paper presents comparative qualitative and quantitative evidence from rural kenya and madagascar in an attempt to untangle the causality behind persistent poverty we find striking differences in welfare dynamics depending on whether one uses total income including stochastic terms and inevitable measurement error or the predictable structural component of income based on a household s asset holdings our results suggest the existence of multiple dynamic asset and structural income equilibria consistent with the poverty traps hypothesis furthermore we find supporting evidence of locally increasing returns to assets and of risk management behaviour consistent with poor households defence of a critical asset threshold through asset smoothing

theories of poverty traps and anti poverty policies in this paper we provide a conceptual overview of alternative mechanisms leading to poverty traps at the individual level making a distinction between those that are due to external frictions e g market failure and those that are due to behavior under extreme scarcity in the absence of any frictions we develop a common theoretical framework to examine alternative scenarios characterizing conditions under which poverty traps in the sense of multiple stable steady states arise as opposed to possibly conditional convergence to a unique steady state we apply this framework to discuss the relative merits of alternative anti poverty policies such as unconditional and conditional cash transfers and direct interventions aimed at improving market access to the poor or improving public service delivery jel codes d13 d23 o12 o15

technology driven inequality leads to poverty and resource depletion the rapid rise in inequality is often seen to go in hand with resource overuse examples include water extraction in pakistan land degradation in bangladesh forest harvesting in sub saharan africa and industrial fishing in lake victoria while access to ecosystem services provided by common pool resources mitigates poverty exclusive access to technology by wealthy individuals may fuel excessive resource extraction and deplete the resource thus widening the wealth gap we use a stylised social ecological model to illustrate how a positive feedback between wealth and technology may fuel local inequality the resulting rise in local inequality can lead to resource degradation and critical transitions such as ecological resource collapse and unexpected increase in poverty further we find that societies may evolve towards a stable state of few wealthy and many poor individuals where the distribution of wealth depends on how access to technology is distributed overall our results illustrate how access to technology may be a mechanism that fuels resource degradation and consequently pushes most vulnerable members of society into a poverty trap

contractual structure and wealth accumulation can historical wealth distributions affect long run output and inequality despite rational saving convex technology and no externalities we consider a model of equilibrium short period financial contracts where poor agents face credit constraints owing to moral hazard and limited liability if agents have no bargaining power poor agents have no incentive to save poverty traps emerge and agents are polarized into two classes with no interclass mobility if instead agents have all the bargaining power strong saving incentives are generated the wealth of poor and rich agents alike drift upward indefinitely and history does not matter eventually d31 d91 i32 o17 q15

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

the economics of poverty traps and persistent poverty empirical and policy implications the moral and economic imperatives to intervene in poverty traps motivate the identification of poverty traps and their structural causes so as to inform the design of appropriate policy responses however empirical identification remains challenging because of poverty traps complexity after reviewing mechanisms that can generate poverty traps we focus on one multiple financial market failures emphasising its heretofore underappreciated testable implications including specific behaviours that are rational only in the presence of a poverty trap we therefore recommend tests for these behaviours rather than more econometrically challenged efforts to directly test for poverty traps in estimated asset dynamics

asset smoothing consumption smoothing and the reproduction of inequality under risk and subsistence constraints abstract a growing literature asks whether low wealth agents can accumulate assets over time or whether they are trapped in poverty this paper develops a stochastic dynamic programming model with endogenous asset price risk to explore savings and portfolio decisions in a resource poor environment characterized by risk and subsistence constraints optimal portfolio strategies are found to bifurcate despite divisible assets and fully rational agents wealthier agents acquire a higher yielding portfolio and pursue conventional consumption smoothing poorer agents acquire a less remunerative portfolio and pursue asset smoothing rather than consumption smoothing asset based risk coping thus results in positive correlation between initial wealth and portfolio rate of return

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

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

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

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

contagious cooperation temptation and ecosystem collapse real world observations suggest that social norms o f cooperation can be effective in overcoming social dilemmas such as the joint management of a c ommon pool resource but also that they can be subject to slow erosion and sudden collapse we show that these patterns of erosion and 15 collapse emerge endogenously in a model of a closed community harvesting a renewable natural resource in which individual agents face the tempta tion to overexploit the resource while a cooperative harvesting norm spreads through the community via interpersonal relations we analyze under what circumstances small changes in key parameters including the size of the community and the rate of technological progress trigger catastrophic transitions from 20 relatively high levels of cooperation to widespread norm violation causing the social ecological system to collapse

profit fluctuations signal eroding resilience of natural resources abstract a common pattern of environmental crises is a vicious cycle between environmental degradation and socio economic disturbances here we show that while such feedbacks may give rise to critical transitions in social ecological systems at the same time they can offer novel opportunities for anticipating them we model a community that has joint access to the harvest grounds of a resource that is prone to collapse individuals are tempted to overexploit the resource while a cooperative harvesting norm spreads through the community via interpersonal relations both social and ecological collapses can be induced by environmental or socio economic driving forces regardless of the type and cause of collapse we find that upcoming transitions may be detected using simple socio economic response variables such as individual profits our findings suggest that such alternative sources of information can be used to detect upcoming critical transitions in social ecological systems however we also find that robust detection of critical transitions may be confounded by recovery attempts undertaken by resource users in the vicinity of an upcoming collapse which may be falsely interpreted as a stabilization of the social ecological system

about capital in the twenty first century in this article i present three key facts about income and wealth inequality in the long run emerging from my book capital in the twenty first century and seek to sharpen and refocus the discussion about those trends in particular i clarify the role played by r g in my analysis of wealth inequality i also discuss some of the implications for optimal taxation and the relation between capital income ratios and capital shares

why do developing countries tax so little the power to tax is taken for granted in a great deal of mainstream public finance in considering limits to taxation traditional research in the field focuses on limits imposed by incentive constraints which are tied to asymmetric information or to politics and political institutions the limits to taxation are rarely tied to the administrative capacity of the state but incentive constraints alone cannot explain the vast differences in the levels of taxation that we see across the world and across time low income countries typically collect taxes of between 10 to 20 percent of gdp while the average for high income countries is more like 40 percent in essence our view on these patterns is similar to that taken by joseph schumpeter 1918 almost a century ago when he noted the fiscal history of a people is above all an essential part of its general history an enormous influence on the fate of nations emanates from the economic bleeding which the needs of the state necessitates and from the use to which the results are put in order to understand taxation economic development and the relationships between them we need to think about the forces that drive the development process poor countries

flows funds and the complexity of deprivation using concepts from ecological economics for the study of poverty abstract poverty has been increasingly conceptualized as being multidimensional involving deprivation in many dimensions of life this paper discusses issues and implications of multidimensional poverty by adopting concepts commonly used in ecological economics in particular poverty is approached as an irreducible complex phenomenon for which many legitimate but non equivalent descriptions exist issues of social and technical incommensurability are illustrated for different meanings and measurement types of poverty georgescu roegen s flow fund framework is interpreted informed by the capability approach of amartya sen the paper argues that a predominant focus on flows as a proxy to analyze poverty represents rather a short term perspective on access to satisfiers to fulfill particular needs contrary to that focusing on valued funds may provide useful information for the analysis of capabilities that persons and societies might pursue in the long term furthermore it is argued that strong poverty alleviation needs to adopt analytical tools that can deal with non trade off cases improvements in one poverty dimension cannot always compensate for the deterioration of other poverties this implies to rethink the usefulness of aggregate multidimensional poverty indices as well as the predominant use of income measures

welfare dynamics in pakistan and ethiopia does the estimation method matter identifying household level welfare dynamics and associated dynamic poverty trap thresholds can have important implications for the targeting of poverty reduction policies the small existing empirical microeconomic literature has found evidence both for and against poverty traps using household panel data from rural pakistan and ethiopia this article examines whether these different results are likely driven by differences in estimation methods or whether they reflect actual differences across settings it applies the estimation methods from the existing literature to the same two datasets and also proposes a novel semiparametric panel data estimator that combines the advantages of the previous fully parametric and nonparametric approaches the results suggest that absent any dynamic poverty trap thresholds the effect of using different estimation methods is secondary having a small influence on the estimated long term level of household well being but not the identification of multiple dynamic welfar

wealth inequality in the united states since 1913 evidence from capitalized income tax data this paper combines income tax returns with flow of funds data to estimate the distribution of household wealth in the united states since 1913 we estimate wealth by capitalizing the incomes reported by individual taxpayers accounting for assets that do not generate taxable income we successfully test our capitalization method in three micro datasets where we can observe both income and wealth the survey of consumer finance linked estate and income tax returns and foundations tax records wealth concentration has followed a u shaped evolution over the last 100 years it was high in the beginning of the twentieth century fell from 1929 to 1978 and has continuously increased since then the rise of wealth inequality is almost entirely due to the rise of the top 0 1 wealth share from 7 in 1979 to 22 in 2012 a level almost as high as in 1929 the bottom 90 wealth share rst increased up to the mid 1980s and then steadily declined the increase in wealth concentration is due to the surge of top incomes combined with an increase in saving rate inequality top wealth holders are younger today than in the 1960s and earn a higher fraction of total labor income in the economy we explain how our ndings can be reconciled with survey of consumer finances and estate tax data

coherent arbitrariness stable demand curves without stable preferences economic theories of valuation generally assume that prices of commodities and assets are derived from underlying fundamental values for example in finance theory asset prices are believed to reflect the market estimate of the discounted present value of the asset s payoff stream in labor theory the supply of labor is established by the tradeoff between the desire for consumption and the displeasure of work finally and most importantly for this chapter consumer microeconomics assumes that the demand curves for consumer products chocolates cds movies vacations drugs and so forth can be ultimately traced to the valuation of pleasures that consumers anticipate receiving from these products because it is difficult as a rule to measure fundamental values directly empirical tests of economic theory typically examine whether the effects of changes in circumstances on valuations are consistent with theoretical prediction for example whether labor supply responds appropriately to a change in the wage rate whether compensated demand curves for commodities are downward sloping or whether stock prices respond in the predicted way to share repurchases however such comparative static relationships are a necessary but not sufficient condition for fundamental valuation e g summers 1986 becker 1962 was perhaps the first to make this point explicitly when he observed that consumers choosing commodity bundles randomly from their budget set would nevertheless produce downward sloping demand curves

trade tragedy and the commons we develop a theory of resource management where the degree to which coun tries escape the tragedy of the commons and hence the de facto property rights regime is endogenously determined three forces determine success or failure in resource management the regulator s enforcement power the extent of har vesting capacity and the ability of the resource to generate competitive returns without being extinguished the model can explain heterogeneity across coun tries and resources in the effectiveness of resource management and it predicts that changes in prices population and technology can cause transitions to better or worse management regimes jel p14 q21 q22 q23 q32 many of the world s major renewable resource stocks are in a state of decline this is true for capture fisheries for forests in developing countries and for many measures of the biosphere s health other renewable resources including many species of wildlife marine mammals and coral reefs are also under threat while poverty and government corruption are surely respon sible for some of this record particular emphasis is often placed on the potentially damaging role played by international trade this emphasis is not surprising given that natural resource products are a key export for much of the developing world and property rights over renewable resources are both difficult to define and poorly enforced but property rights are not an immutable country characteristic such as weather mineral deposits or topography they are instead market institutions developed to facilitate transactions and protect scarce resources consequently changes in prices technology and other effects of market integration may alter the de facto property rights regime and lead to impacts quite dif ferent from those predicted by existing analyses the purpose of this paper is to examine renew able resource use within a framework where the enforcement of property rights and hence the efficacy of resource management is endogenously determined we develop a theory where an existing government regulates the use of a renewable resource by a set of agents who have a right to harvest the resource could be a fishery forest stock aquifer etc and we assume it is local and therefore contained within one country the govern ment sets rules limiting harvests but agents may cheat on these allocations and risk punishment property rights are endogenous in this framework because the government must account for agents incentive to cheat as a result the effective protection for the resource or what we refer to as the de facto property rights regime may be far from perfect even though property rights would be perfectly enforced if there was no monitoring problem

empirical regularities in the poverty environment relationship of rural households evidence from zimbabwe abstract analysis of rural households and environmental resources is beset by inadequate data especially in africa using purpose collected panel data from zimbabwe we demonstrate seven empirical regularities in the rural poverty environment relationship most important environmental resources make a significant contribution to average rural incomes poorer households also depend heavily on these resources which contribute c 40 to their incomes richer households however use greater quantities of environmental resources in total finally considerable differentiation exists in the economic characteristics of environmental goods these results demonstrate the considerable economic significance of environmental resources to rural households surveys which ignore them miscalculate rural incomes and welfare
