distributional weights in cost benefit analysis should we forget about them many argue that it is socially inefficient to use distributional weights in cost benefit analysis and that doing so implies large inefficiency losses when distributional matters can be dealt with trough income taxation instead our results question this view by showing a large range of cases when distributional weights are second best optimal to use one example is when different provided goods affect tax revenues equally per dollar spent utility functions that are separable in the provided goods is sufficient for this most results hold for linear and non linear income taxes and whether they are optimal or not general policy implications are discussed

investor valuation of the abandonment option abstract we investigate whether investors price the option to abandon a firm at its exit value theory prices this real option as an american put with both a stochastic strike price exit value and a stochastic value of the underlying security the value of cash flows the empirical implications are that firm value increases in exit value after controlling for expected going concern cash flows and that more generalizable assets produce more abandonment option value using discounted earnings forecasts to proxy for expected cash flows and prior literature to categorize asset generalizability we find strong support for the predictions of abandonment option theory

evidence on changes in aid allocation criteria have donors changed their aid allocation criteria over the past three decades toward greater selectivity a frequently stated goal of the international development community using data on how 22 donors allocated their bilateral aid among 147 countries over 1970 2004 the article finds that after the fall of the berlin wall in 1989 and especially in the late 1990s bilateral aid responded more to poverty and the quality of the policy and institutional environment in the recipient countries furthermore the sensitivity of aid allocation to the country s size and its debt burden has declined over time these results are robust to different samples and model specifications various econometric techniques and alternative measures of institutional quality while the specific factors causing these changes cannot be identified these presumably include geopolitical and economic concerns and the many changes in the international aid architecture donors still differ greatly in their selectivity this suggests that further multifaceted reforms are needed to ensure even greater selectivity of aid

the political economy of state failure rapid decolonization created many arbitrary countries in contrast to those states which had emerged through a quasi darwinian process of selection some of these new countries had structural characteristics which gravely impeded the provision of public goods their lack of a unifying sense of shared identity made cooperation difficult and their tiny economic size left them unable to reap scale economies two public goods security and accountability are particularly important for development and so where they could not be provided states failed the cause of a problem is not necessarily a guide to its solution darwinian struggle among failing states is not something to be encouraged solutions lie partly in a phase of international provision of the key public goods partly in enhanced regional pooling of sovereignty and partly in institutional innovation to make the domestic provision of public goods less demanding of the state copyright 2009 oxford university press

aid policy and growth in post conflict societies countries emerging from civil war attract both aid and policy advice this paper provides the first systematic empirical analysis of aid and policy reform in the post conflict growth process it is based on a comprehensive data set of large civil wars and covers 27 countries that were in their first decade of post conflict economic recovery during the 1990s the authors first investigate whether the absorptive capacity for aid is systematically different in post conflict countries they find that during the first three post conflict years absorptive capacity is no greater than normal but that in the rest of the first decade it is approximately double its normal level so ideally aid should phase in during the decade historically aid has not on average been higher in post conflict societies and it has tended to taper out over the course of the decade the authors then investigate whether the contribution of policy to growth is systematically different in post conflict countries and in particular whether particular components of policy are differentially important for this they use the world bank policy rating database the authors find that growth is more sensitive to policy in post conflict societies comparing the efficacy of different policies they find that social policies are differentially important relative to macroeconomic policies however historically this does not appear to have been how policy reform has been prioritized in post conflict societies

project appraisal and planning twenty years on this paper discusses the use and usefulness of social cost benefit analysis it briefly recalls the main features of the procedures put forward in the book by the authors and addresses some of the issues that have arisen in theoretical work since the early 1970s particularly the implications of uncertainty an analysis of the value of project appraisal under uncertainty is provided the rise and decline of project appraisal in the world bank and elsewhere is charted and reasons are considered particular attention is given to the difficulty of using shadow prices and to the institutional environment it is argued that evidence from analysis of the world bank s projects is consistent with placing a high value on the process of economic appraisal the costs of appraisal are noted as is the need to avoid excessive complexity the paper argues for the importance of an economic appraisal system and of attending to the incentives that operate in such a system

looking ahead optimally in allocating aid summary the collier dollar approach to aid allocation among countries has been less than fully embraced by donors even those focused on poverty reduction partly because it conflicts with the approach to aid allocation implied by the millennium development goals these two approaches are shown to be special cases of a more general model of aid allocation in which donors care about future as well as current poverty this model is illustratively applied to data for developing regions adding a poverty decline adjustment to the allocation formulae used by donors could resolve the conflict between the two approaches

on the empirics of foreign aid and growth the present paper re examines the effectiveness of foreign aid theoretically and empirically using a standard olg model we show that aid inflows will in general affect long run productivity the size and direction of the impact may depend on policies deep structural characteristics and the size of the inflow the empirical analysis investigates these possibilities overall we find that aid has been effective in spurring growth but the magnitude of the effect depends on climate related circumstances finally we argue that the collier dollar allocation rule should be seriously reconsidered by donor agencies if aid effectiveness is related to climate the usefulness of foreign aid in promoting growth in developing countries has been an area of controversy ever since rosenstein rodan in 1943 advocated for aid to eastern and south eastern europe browsing through successive editions of a leading textbook in development economics provides a telling illustration of how the confidence in aid effectiveness dwindled over the years in the first edition of leading issues in economic development meier 1964 dedicated a full 18 page section to the issue of foreign aid he started out asking how much aid by the time of the sixth edition meier 1995 the treatment of foreign aid had been cut into half and the questions in focus were why official assistance and does aid work in the 2000 edition meier and rauch 2000 foreign aid is not even listed in the index

does aid availability affect effectiveness in reducing poverty a review article this paper addresses the impact of aid supply on aid effectiveness first we review theoretical literature that deals with the problem of governance in donor recipient relationships and are susceptible of highlighting effects of aggregate aid availability second we provide a conceptual framework that explicitly incorporates a trade off between considerations of needs and governance we examine the impact of aid supply on the manner in which a donor agency allocates the available money between countries differing in terms of both needs and domestic governance the central conclusion is that a donor s utility function that embodies the need governance trade off and the associated optimization mechanism yield a meaningful rule to guide inter country allocation of aid resources

fairness in the international allocation of development aid this paper assesses the allocative performance of foreign aid donors it does so by identifying the consistency of the share of donor aid allocated to each developing country with these their shares of global poverty a given donor s allocative performance is maximised if the share of its aid to each developing country exactly equals its share of global poverty this is equated with fairness in the international allocation of aid the allocative performance of all donors all bilateral donors all multilateral agencies all non dac donor countries the eu france germany japan the united kingdom and the united states for the years 2010 15 is assessed the best performance is exhibited by all bilateral donors while that for an individual donor is exhibited by the united kingdom non dac donors exhibit the worst performance the paper also identifies which developing countries receive the most and least aid relative to their shares of global poverty

conditional earnings conservatism and corporate refocusing activities we extend standard models of conditional earnings conservatism and adaptation value to the context of the corporate refocusing activities of uk listed companies this analysis is interesting because refocusing activities are 1 commonly anticipated by significant negative returns in the financial year s before the refocusing event 2 typically associated with large material charges and 3 likely to be part of a strategic plan with the internal decision preceding the formal public announcement we complement burgstahler and dichev 1997 by showing how their nonlinear relation between share prices and earnings changes around refocusing events as adaptation options are exercised because refocusing events also involve large realized losses and major changes to firms strategic plans we expect to see systematic changes in the timing relations between stock returns and reported earnings to capture this we show how the coefficients of basu s 1997 model of conditional conservatism change around refocusing events

project evaluation and uncertainty in practice a statistical analysis of rate of return divergences of 1 015 world bank projects this article analyzes the world bank s experience with project evaluation for a sample of 1 015 projects by comparing estimated rates of return at appraisal with reestimated rates of return when construction works are completed usually 5 to 10 years after appraisal the analysis highlights the high degree of uncertainty in project analysis a wide range of variables has been introduced to explain the observed divergence in appraisal and reestimated rates of return but only a relatively small part of the divergence can be explained even with the benefit of hindsight project analysis thus has to cope with a large degree of uncertainty which the traditional methods of project evaluation and selection have not been able to reduce

aid allocation rules abstract this paper studies an aid allocation rule used by major development agencies and investigates optimal allocations when recipients are neoclassical economies undergoing transition dynamics when recipients face aid absorption constraints allocations that favor poorer recipients are not always optimal contrary to what is assumed in assessments of donor performance the most quantitatively significant factors that determine the optimal sensitivity to recipient characteristics are the generosity of the aid budget and the extent of absorption constraints in neoclassical recipients aid can only accelerate growth where there is already growth so the optimal rule places little weight on growth and optimality is largely a matter of balancing recipient need against absorption constraints

a theory of collective reputations with applications to the persistence of corruption and to firm quality the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by his past behaviour and because his track record is observed only with noise by the group s past behaviour as well the paper thus studies the joint dynamics of individual and collective reputations and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality 1 collective reputations collective reputations play an important role in economics and the social sciences countries ethnic racial or religious groups are known to be hard working honest corrupt hospitable or belligerent some firms enjoy substantial rents from their reputations for producing high quality products some departments are reported to treat their faculty or students fairly the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by her past behaviour and because her track record is observed only with noise by the group s past behaviour as well the paper studies the joint dynamics of individual and collective reputations in a model in which current generations are progressively replaced by new ones and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature see section 2 for a detailed comparison with the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality let us spell out the building blocks of our theory in more detail a a group s reputation is only as good as that of its members each member is characterized by individual traits such as talent diligence or honesty past individual behaviour conveys information about these traits and generates individual reputations

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

efficiency results in n player games with imperfect private monitoring abstract we demonstrate that efficiency is achievable in a certain class of n player repeated games with private almost perfect monitoring our equilibrium requires only one period memory and can be implemented by two state automata furthermore we show that this efficiency result holds with any degree of accuracy of monitoring if private signals are hemiindependent whereas most existing research focuses on two player cases or only a special example of n player games our results are applicable to a wide range of n player games of economic relevance such as trading goods games and price setting oligopolies

post conflict transitions an overview in the two to five years immediately following end of conflicts united nations un peacekeeping operations have succeeded in maintaining peace while income and consumption growth rates have been higher than normal and recovery on key education and health indicators has been possible aid also has been super effective in promoting recovery not only by financing physical infrastructure but also by helping in the monetary reconstruction of post conflict economies however sustaining these short term gains was met with two difficult challenges first long term sustainability of peace and growth hinges primarily on the ability of post conflict societies to develop institutions for the delivery of public goods which in turn depends on the capacity of post conflict elites to overcome an entrenched culture of political fragmentation and form stable national coalitions beyond their immediate ethnic or regional power bases second after catch up growth runs its course high levels of aid can lead to overvalued real currencies at a time when growth requires a competitive exchange rate and economic diversification successful peace building will therefore require that these political and economic imperatives of post conflict transitions be accounted for in the design of un peacekeeping operations as well as the aid regime

the information content of losses abstract this study hypothesizes that because shareholders have a liquidation option losses are not expected to perpetuate they are thus less informative than profits about the firm s future prospects the results are consistent with the hypothesis they also show that the documented increase in the earnings response coefficent as the cumulation period increases appears to be due exclusively to the effect of losses the liquidation option effect extends to profitable cases where earnings are low enough to make the option attractive alternating explanations for the low informativeness of losses such as mean reversal of earnings are not supported by the tests

the role of accruals in asymmetrically timely gain and loss recognition we investigate the role of accrual accounting in the asymmetrically timely recognition incorporation in reported earnings of gains and losses timely recognition requires accruals when it precedes complete realization of the gains and losses in cash we show that nonlinear accruals models incorporating the asymmetry in gain and loss recognition timelier loss recognition or conditional conservatism offer a substantial specification improvement explaining substantially more variation in accruals than equivalent linear specifications conversely conventional linear accruals models by omitting the loss recognition asymmetry exhibit substantial attenuation bias and offer a comparatively poor specification of the accounting accrual process linear specifications also understate the ability of current earnings to predict future cash flows these findings have implications for our understanding of accrual accounting and conservatism as well as for researchers estimating discretionary accruals earnings management and earnings quality

management by the numbers a formal approach to deriving informational and distributional properties of unmanaged earnings we explore the theoretical relation between earnings and market returns as well as the properties of earnings frequency distributions under the assumption that managers use unbiased accounting information to sequentially decide on real options their firms have and report generated earnings truthfully with the market pricing the firm based on those reported earnings we generate benchmarks against which empirically observed earnings returns relations and aggregate earnings distributions can be evaluated this parsimonious model shows a coherent set of results reported losses are less persistent than reported gains decision making diminishes the s shaped market response to earnings and earnings relate to returns asymmetrically in the way documented by basu 1997 furthermore the implied frequency distribution of aggregate earnings is neither symmetric nor necessarily single peaked instead it may exhibit a kink at zero and look similar to the plots reported by burgstahler and dichev 1997 however within our model none of these phenomena are due to reporting noise bias or some undesirable strategic managerial behavior they are the natural consequences of using past earnings as the basis for value increasing managerial decision making that in turn generates the future earnings on which future decisions will be based

environmental issues and economic decisions in developing countries abstract this paper explains the key role of environmental economics in incorporating environmental concerns into decision making and in facilitating the more efficient management of natural resources as a step toward sustainable development it reviews concepts and techniques for valuation of environmental impacts for use in conventional cost benefits analysis as well as key related aspects including environmental impacts of economywide policies multicriteria analysis risk and uncertainty and discount rate issues several developing country case studies are summarized which cover a range of practical valuation methods the evidence presented suggests that the valuation techniques for determining use values may be applied successfully in appropriate cases but examples involving nonuse values are rare the use of multiobjective desicion methods also needs to be explored where economic valuation is not feasible

individual learning and cooperation in noisy repeated games we investigate whether two players in a long run relationship can maintain cooperation when the details of the underlying game are unknown specifically we consider a new class of repeated games with private monitoring where an unobservable state of the world influences the payoff functions and or the monitoring structure each player privately learns the state over time but cannot observe what the opponent learned we show that there are robust equilibria in which players eventually obtain payoffs as if the true state were common knowledge and players played a belief free equilibrium we also provide explicit equilibrium constructions in various economic examples copyright 2014 oxford university press

the folk theorem with imperfect public information the authors study repeated games in which players observe a public outcome that imperfectly signals the actions played they provide conditions guaranteeing that any feasible individually rational payoff vector of the stage game can arise as a perfect equilibrium of the repeated game with sufficiently little discounting the central condition requires that there exist action profiles with the property that for any two players no two deviations one by either player give rise to the same probability distribution over public outcomes the results apply to principal agent partnership oligopoly and mechanism design models and to one shot games with transferable utilities copyright 1994 by the econometric society

aid allocation by german ngos does the degree of official financing matter using a new data set for 41 german non governmental organisations ngos we analyse the allocation of ngo aid across recipient countries in a tobit regression framework by identifying for each ngo the degree of official financing we address the largely unresolved issue of whether financial dependence on the government impairs the targeting of ngo aid it turns out that german ngos are more active in poorer countries while they do not complement official aid by working under difficult local conditions beyond a certain threshold rising financial dependence weakens their poverty orientation and provides an incentive to engage in easier environments in addition we find that the ngos follow the state as well as ngo peers when allocating aid this herding behaviour is however hardly affected by the degree of official financing

effective foreign aid following civil war the nonstrategic desperation hypothesis when does aid foster development after civil war a testable model is needed to account for the uneven outcomes in postconflict development this article proposes and empirically tests the novel nonstrategic desperation hypothesis an explanation based on the varied incentives that fragile postconflict governments face when confronted with donor development goals paradoxically incentives to meet development goals only exist when donors have little strategic interest in the recipients and when recipients lack income from resource rents and are therefore desperate for income ten year data on infant mortality changes following civil wars ending 1970 96 and a variety of robustness checks support the hypothesis by focusing on how income sources constrain the choices of aid recipients and how these constraints can provide incentives to meet donor development goals the nonstrategic desperation hypothesis explains how the good use of aid can take place following civil war when institutions are weak

aid selectivity according to augmented criteria a dominant trend in the literature maintains that donor assistance should be targeted to poor countries with sound institutions and policies in this context donor selectivity refers to what extent aid is allocated according to the principles of this canonical model this paper shows that it is legitimate for donors to simultaneously use other selectivity criteria corresponding either to expected factors of aid effectiveness or to handicaps to development it is notably argued that vulnerability to exogenous shocks and low level of human capital should be considered as selectivity criteria taking these other criteria into account dramatically changes the assessment of donor selectivity

postconflict monetary reconstruction during civil wars governments typically resort to inflation to raise revenue a model of this phenomenon is presented estimated and applied to the choices and constraints faced during the post conflict period the results show that far from there being a fiscal peace dividend post conflict governments tend to face even more pressing needs after than during war as a result in the absence of post conflict aid inflation increases sharply frustrating a more general monetary recovery aid decisively transforms the path of monetary variables in the post conflict period enabling the economy to regain peacetime characteristics post conflict aid thus achieves a monetary reconstruction analogous to its more evident role in infrastructure

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

can the world cut poverty in half how policy reform and effective aid can meet international development goals abstract poverty in the developing world will decline by about one half by 2015 if the trends of the 1990s persist most of this poverty reduction will occur in asia however while poverty will decline only slightly in africa effective aid could make a contribution to greater poverty reduction in lagging regions even more potent would be significant policy reform in these countries we develop a model of efficient aid in which flows respond to policy improvements that create a better environment for poverty reduction and effective aid we investigate scenarios of policy reform and efficient aid that point the way to how the world can cut poverty in half in every major region

communication in repeated games with imperfect private monitoring this paper examines repeated games in which each player observes a private and imperfect signal on the actions played and in which players are allowed to communicate using public messages providing incentives for players to reveal their observations generates revelation constraints that combined with signal imperfections may be a source of inefficiencies however by delaying the revelation of their observations players may economize on the cost of deterring deviations and thereby avoid these inefficiencies because a player would not want to trigger a sanction that would penalize him too revelation constraints also tend to make sanctions difficult to enforce however with at least three players detecting deviations may not require that all the players reveal their observations in that case we obtain a nash threat version of the folk theorem with two players we do not obtain a similar result nevertheless we show that an efficient outcome can almost always be approximated

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

do developing country wto members receive more aid for trade aft since the world trade organization wto doha development agenda dda negotiations started in 2001 the importance of aid for trade aft has been well recognised as a useful tool for facilitating trade economic growth and social development in developing countries at the wto hong kong ministerial conference in december 2005 the aft initiative was launched and many high income member countries pledged to increase their aft contributions particularly for the least developed member countries ldc this paper aims to assess whether and to what extent the wto s developing member countries have received more aft for this purpose a system generalised method of moments is applied to a sample of 118 recipient countries for the period 2001 10 we find evidence that while ldc wto members on average receive relatively more aft than other developing countries the difference has not increased since launch of the aft initiative among the three categories of aft the positive wto membership effect for ldc members increased for building productive capacity and for trade policy and regulation but declined for infrastructure

restricted feedback in long term relationships abstract this paper studies long term relationships modeled as repeated games with restricted feedback players condition current play on summary statistics of past play rather than the entire history as may be the case in online markets our state strategy equilibrium framework allows for arbitrary restrictions on strategies we derive a recursive characterization for the set of equilibrium payoffs similar to that of abreu pearce and stacchetti 1986 1990 2 3 for perfect public equilibria and show that the set of equilibrium payoffs is the largest fixed point of a monotone operator we use our characterization to derive necessary and sufficient conditions for efficient trade in a repeated product choice game where costumers condition their purchase decisions only on the last performance signal

ecology sustainability and environment as capital abstract the idea of environment as capital has found widespread support in both the economic and ecological literature it is often suggested in a related sustainability literature that natural capital should remain intact if possible the popularity of this approach to exploring the human environment relationship is due in part to the way it is seemingly legitimised by ecological theory and practice this legitimation is important for emerging areas of human environment study such as ecological economics because ecology and other natural sciences have often dismissed economic constructions of the environment however a closer examination of the state of contemporary ecology suggests that there are problems with an ecological legitimation of the environment as capital approach first ecology itself is a troubled discipline and its ability to provide a comprehensive theory of human environment interactions is limited second emerging ecological discourse tends to undermine the ecological rationale for many natural capital related resource management recommendations this does not mean that the environment as capital concept is without considerable heuristic power it does imply however a need to return to a social construction of the environment in which different environmental possibilities are valued in terms of their potential contribution to human well being

assessing the economic vulnerability of small island developing states and the least developed countries macro vulnerability of the small island developing states sids as well as of least developed countries ldcs has been an increasing concern for the international community this has led to the design of an economic vulnerability index evi to assess the structural economic vulnerability resulting from natural or external shocks we first explain how vulnerability affects growth development and poverty reduction particularly in small developing countries we then examine how the evi has been designed and how it can be used to compare sids and ldcs we argue that evi is a relevant tool not only for identification of ldcs but also for geographical aid allocation to favour vulnerable countries including ldcs and sids even though not all sids qualify as ldcs

social protection 2 0 exploring issues evidence and debates in a globalizing world abstract this paper reviews the growing literature on social protection while not new the concept evolved remarkably in recent years it is approached from a multitude of perspectives and intersects with broader bodies of literature particularly around public policy pro poor growth rights humanitarian strategies and aid effectiveness as well as feeding into specific programmatic issues e g conditionality targeting and transfer selection this blend of challenges and approaches has often made debates elusive and polarized the paper examines the evolution and definitions of social protection and unbundles critical policy institutional and implementation quandaries taken together these considerations shape a set of context specific models of social protection the paper s five core conclusions may help chart future directions for social protection research and practice

investment dynamics and earnings return properties a structural approach we propose the standard neoclassical model of investment under uncertainty with short run adjustment frictions as a benchmark for earnings return patterns absent accounting influences we show that our proposed benchmark generates a wide range of earnings return patterns documented in accounting research notably our model generates a concave earnings return relation similar to that of basu 1997 and predicts that the earnings return concavity increases with the volatility of firms underlying shock processes and decreases with the level of firms investments we find strong empirical support for these predictions overall our evidence suggests that our proposed benchmark is useful for understanding the joint dynamics of variables of interest to accounting research e g earnings returns investment market to book absent accounting influences a necessary precondition for inferring the effects of accounting from these dynamics

aid and performance a reassessment two visions of aid effectiveness and allocation are compared the first corresponding to the new aid paradigm argues that aid is only effective if domestic policies are appropriate the second in contrast argues that aid effectiveness depends on the external and climatic environment the worse this environment or the more vulnerable the recipient countries the greater the effectiveness of aid cross sectional econometric tests related to gdp growth on two 12 year pooled periods clearly favour the second view the two views can be reconciled through the principle of performance based aid allocation where performance is defined as outcomes adjusted for the impact of environmental factors performance can then be measured in several manners which are subject to comparison one approach would lead one to allocate more aid the worse the external environment is for a given policy and the better the policy is for a given environment

where do the poor live this paper argues that the distribution of global poverty has changed and that most of the world s poor no longer live in countries officially classified as low income countries lics it is estimated that the majority of the world s poor or up to a billion people live in middle income countries mics this pattern is largely as a result of the recent graduation into the mic category of a number of populous countries the paper discusses the trends in the distribution of global poverty and opens a wider discussion on the potential implications for aid and development cooperation

darlings and orphans interactions across donors in international aid we examine how bilateral aid flows of an individual donor to a recipient depend on aid flows from all other bilateral and multilateral donors to that recipient we thereby assess to what extent issues including donor coordination free riding selectivity specialization and common donor interests drive bilateral aid allocations we find that others bilateral flows lead to a significant increase in aid flows from a particular donor but primarily within a given year the effects are particularly pronounced for large donors and so called darling recipients overall the results suggest that herding is a dominant feature of aid inter relationships this article is protected by copyright all rights reserved

nation building and economic growth nation building the joint provision of economic and military aid in conflict or postconflict areas has been used as an important and expensive foreign policy tool yet despite the huge costs of these investments the growth effects of nation building operations for recipient nations remain underexplored while recent literature documents the negative growth effects of conflict yamarik johnson and compton 2010 and the positive effects of economic aid after conflict collier and hoeffler 2002 very little has been done on the confluence of different kinds of aid and the effectiveness of such joint efforts during times of turmoil this paper attempts to answer the following three questions regarding the growth effects of nation building operations does the joint provision of economic and military assistance help a country grow when it is embroiled in conflict does such joint provision

a paradox of redistribution in international aid the determinants of poverty oriented development assistance summary donors differ in the amount of official development assistance dedicated to poverty reduction we investigate the causes of variation over time and donors by employing both a regression approach with aggregate data on bilateral aid and two short country studies on germany and the united kingdom we find that there is a trade off between the total amount of money given and the amount of money given to poor countries the trade off is similar to the paradox of redistribution of targeting vs redistribution in rich welfare states case study evidence illustrates how countries have managed this tradeoff

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

repeated games with private monitoring two players we investigate two player infinitely repeated games where the discount factor is less than but close to unity monitoring is private and players cannot communicate we require no condition concerning the accuracy of players monitoring technology we show the folk theorem for the prisoners dilemma with conditional independence we also investigate more general games where players private signals are correlated only through an unobservable macro shock we show that efficiency is sustainable for generic private signal structures when the size of the set of private signals is sufficiently large finally we show that cartel collusion is sustainable in price setting duopoly

integration of environmental concerns into economic analyses of projects and policies in an operational context abstract the efficient use of natural resources both mineral and biological as well as man made capital and human resources is a vital prerequisite for economic and social development one key role of ecological economics is to help value environmental and natural resources more precisely and internalize the cost and benefits of using such resources into the decision making process this paper reviews current economic approaches to the analysis of projects and policies and discusses possibilities for better intergrating environmental concerns into public decision making it reviews current practices as they relate to project analysis the analysis of economic policies and national income accounting a major need at present is not for more theory or techniques but for application of existing methodology and approaches to concrete problems particularly in developing countries the major objective should not be to provide fine turned numbers but to indicate orders of magnitude some project and policy alternatives can be ruled out in this fashion also one can often identify the key estimates to which the decision is sensitive and focus more refined analyses on them cost benefit analysis should be used to the extent possible alongside one needs to consider and to the extent possible rigorously analyze consequences and risks that cannot be measured in monetary terms and use for example multi criteria analysis where possible this together with sound judgement are at present the best inputs into decision making

non discretionary conservatism evidence and implications a large body of accounting research finds that various contracting incentives lead managers to engage in conservative accounting practices we extend existing research by modeling the impact of extant accounting rules on conservative accounting accounting rules typically require assets to be written down when their fair values drop sufficiently below their book values we document evidence of the resulting non discretionary conservatism and show that it appears to explain some of the results from previous research on contracting incentives

money is memory abstract this paper examines the sets of feasible allocations in a large class of economic environments in which commitment is impossible following myerson 8 the standard definition of feasibility is adapted to take account of the lack of commitment the environments feature either memory or money memory is defined as knowledge on the part of an agent of the full histories of all agents with whom he has had direct or indirect contact in the past money is defined as an object that does not enter utility or production functions and is available in fixed supply the main proposition is that any allocation that is feasible in an environment with money is also feasible in the same environment with memory depending on the environment the converse may or may not be true hence from a technological point of view money is equivalent to a primitive form of memory journal of economic literature classification numbers e40 c73 d82

collusion in dynamic bertrand oligopoly with correlated private signals and communication abstract this paper studies collusion in repeated bertrand oligopoly when stochastic demand levels for the product of each firm are their private information and are positively correlated it derives general sufficient conditions for efficient collusion through communication and a simple grim trigger strategy this analysis is then applied to a model where the demand signal has multiple random components which respond differently to price deviations in this model it is shown that the above sufficient conditions hold if idiosyncratic noise terms are sufficiently small journal of economic literature classification numbers c72 d82

aid allocation and poverty reduction the authors derive a poverty efficient allocation of aid and compare it with actual aid allocations they build the poverty efficient allocation in two stages first they use new world bank ratings of 20 different aspects of national policy to establish the current relationship between aid policies and growth onto that they add a mapping from growth to poverty reduction which reflects the level and distribution of income they compare the effects of using headcount and poverty gap measures of poverty they find the actual allocation of aid to be radically different from the poverty efficient allocation in the efficient allocation for a given of poverty aid tapers in with policy reform in the actual allocation aid tapers out with reform in the efficient allocation aid is targeted disproportionately to countries with severe poverty and adequate polices the type of country where 74 percent of the world s poor live in the actual allocation such countries receive a much smaller share of aid 56 percent than their share of the world s poor with the present allocation aid is effective in sustainably lifting about 30 million people a year out of absolute poverty with a poverty efficient allocation this would increase to about 80 million people even with political constraints introduced to keep allocations for india and china constant poverty reduction would increase to about 60 million reallocating aid is politically difficult but it may be considerably less difficult than quadrupling aid budgets which is what the authors estimate would be necessary to achieve the same impact on poverty reduction with existing aid allocations

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

relative valuation roles of equity book value and net income as a function of financial health abstract this study tests predictions that pricing multiples on and incremental explanatory power of equity book value net income increase decrease as financial health decreases tests using a sample of 396 bankrupt firms and tests using a larger pooled sample both yield inferences consistent with predictions findings are robust to inclusion of controls for industry size return on equity and volatility of equity returns equity book value and net income multiples and incremental explanatory power vary predictably across three illustrative industries selected based on the likely extent of unrecognized intangible assets

how robust is the folk theorem the folk theorem of repeated games has established that cooperative behavior can be sustained as an equilibrium in repeated settings early papers on private monitoring and a recent paper of cole and kocherlakota games and economic behavior 53 2005 59 72 challenge the robustness of this result by providing examples in which cooperation breaks down when players observe only imperfect private signals about other players actions or when attention is restricted to strategies with finite memory this paper shows that cole and kocherlakota s result is an artefact of a further restriction that they impose we prove that the folk theorem with imperfect public monitoring holds with strategies with finite memory as a corollary we establish that the folk theorem extends to environments in which monitoring is close to public yet private

dangerous interactions problems in interpreting tests of conditional aid effectiveness there is now a substantial empirical literature examining the determinants of aid effectiveness a large part of this makes inferences based on a regression incorporating aid as a share of recipient gdp interacted with some institutional or policy variable recently some authors have questioned the statistical robustness of such regressions pointing out that results vary according to the way aid is measured and the estimator applied to the data moreover the regression equations used to test hypotheses about the determinants of aid effectiveness are often introduced without any corresponding formal theory we explore aid policy interaction terms in the context of a simple theoretical model showing how different nonlinearities may be conflated the resulting difficulties in the interpretation of aid growth regressions are illustrated in the context of a seminal paper in the conditional aid effectiveness literature one simple change in the way that aid is measured in per capita terms rather than as a fraction of gdp completely changes the regression results this indicates that adding interaction terms to otherwise linear regression equations is an inadequate way of capturing the nonlinearities in the growth process our aim is to re emphasise the importance of grounding

why are losses less persistent than profits curtailments vs conservatism it is well documented that losses are less persistent than profits and that stock prices anticipate the lower persistence of losses yet the underlying explanation for these results is unclear one explanation lies in the abandonment option whereby firms with losses are more likely to curtail operations e g hayn hayn c 1995 the information content of losses j accounting econom 20 2 125 153 another explanation involves timely loss recognition stemming from conservative accounting e g basu basu s 1997 the conservatism principle and the asymmetric timeliness of earnings j accounting econom 24 1 3 37 we provide direct evidence that curtailments are an important factor contributing to the lower persistence of losses an implication of our results is that popular measures of conservatism such as the measure proposed by basu also reflect curtailments this paper was accepted by suraj srinivasan accounting

the folk theorem for repeated games with observation costs abstract the folk theorem literature has been relaxing the assumption on how much players know about each other s past action here we consider a general model where players can buy precise information every period each player decides whether to pay a cost to accurately observe the actions chosen by other players in the previous period when a player does not pay the cost he obtains only imperfect private signals observational decisions are unobservable to others known strategies such as trigger strategies do not work since they fail to motivate players to pay for information this paper shows that the folk theorem holds for any level of observation costs unlike existing folk theorems with private monitoring ours imposes virtually no restriction on the nature of costless imperfect signals the theorem does not use explicit or costless communication thereby having implications on antitrust laws that rely on evidence of explicit communication the main message is that accurate observation alone however costly enables efficient cooperation in general repeated games

asymmetric loan loss provision models abstract large net loan charge offs are frequently associated with large decreases in nonperforming loans and large increases in loan loss provisions inducing a v shaped relation between loan loss provisions and nonperforming loan changes failure to model the asymmetry attributable to net loan charge offs can change inferences about the presence of earnings management and the effects of delayed loan loss recognition in prior papers that assumed linearity future researchers should either include net loan charge offs in linear models of loan loss provisions or explicitly model the asymmetry induced by omitting net loan charge offs
