to float or to fix evidence on the impact of exchange rate regimes on growth we study the relationship between exchange rate regimes and economic growth for a sample of 183 countries over the post bretton woods period using a new de facto classification of regimes based on the actual behavior of the relevant macroeconomic variables in contrast with previous studies we find that for developing countries less flexible exchange rate regimes are associated with slower growth as well as with greater output volatility for industrial countries regimes do not appear to have any significant impact on growth the results are robust to endogeneity corrections and a number of alternative specifications borrowed from the growth literature

the changing time series properties of earnings cash flows and accruals has financial reporting become more conservative abstract this paper documents changes in the patterns of earnings cash flows and accruals over the last four decades in the absence of a generally accepted definition of conservatism a number of measures of reporting conservatism are identified and examined these measures rely on the accumulation of nonoperating accruals the timeliness of earnings with respect to bad and good news characteristics of the earnings distribution and the market to book ratio the patterns are consistent with an increase in conservative financial reporting over time the findings have implications for accounting standard setting regulation of financial information and financial statement analysis

exchange arrangements entering the twenty first century which anchor will hold this article provides a comprehensive history of anchor or reference currencies exchange rate arrangements and a new measure of foreign exchange restrictions for 194 countries and territories over 1946 2016 we find that the often cited post bretton woods transition from fixed to flexible arrangements is overstated regimes with limited flexibility remain in the majority even if central bankers communications jargon has evolved considerably in recent decades it is apparent that many still place a large implicit weight on the exchange rate the u s dollar scores as the world s dominant anchor currency by a very large margin by some metrics its use is far wider today than 70 years ago in contrast the global role of the euro appears to have stalled we argue that in addition to the usual safe assets story the record accumulation of reserves since 2002 may also have to do with many countries desire to stabilize exchange rates in an environment of markedly reduced exchange rate restrictions or more broadly capital controls an important amendment to the conventional portrayal of the macroeconomic trilemma

international financial integration and crisis contagion international financial integration helps to diversify risk but also may spread crises across countries we provide a quantitative analysis of this trade off in a two country general equilibrium model with collateral constrained borrowing using a global solution method borrowing constraints bind occasionally depending upon the state of the economy and levels of inherited debt we examine different degrees of international financial integration moving from financial autarky to bond and equity market integration financial integration leads to a significant increase in global leverage substantially escalates the probability of crises for any one country and dramatically increases the degree of contagion across countries outside of crises the impact of financial integration on macroeconomic aggregates is relatively small but the impact of a crisis with integrated international financial markets is much less severe than that under financial market autarky thus a trade off emerges between the probability of crises and the severity of crises using a large cross country database of financial crises in developing and developed economies over a forty year period we find evidence in support of the model

business cycles theory evidence and policy implications this paper looks at recent advances in the study of aggregate fluctuations the emphasis is on three prominent areas of research the stochastic growth model economies which exhibit macroeconomic complementarities and models that emphasize heterogeneity each section of the paper outlines the theory examines relevant empirical evidence and then discusses some policy implications of the analysis

liquidity effects and the monetary transmission mechanism several recent papers provide strong empirical support for the view that an expansionary monetary policy disturbance generates a persistent decrease in interest rates and a persistent increase in output and employment existing quantitative general equilibrium models which allow for capital accumulation are inconsistent with this view there does exist a recently developed class of general equilibrium models which can rationalize the contemporaneous response of interest rates output and employment to a money supply shock however a key shortcoming of these models is that they cannot rationalize persistent liquidity effects this paper discusses the basic frictions and mechanisms underlying this new class of models and investigates one avenue for generating persistence we argue that once a simplified version of the model in christiano and eichenbaum 1991 is modified to allow for extremely small costs of adjusting sectoral flow of funds positive money shocks generate long lasting quantitatively significant liquidity effects as well as persistent increases in aggregate economic activity

living and dying with hard pegs the rise and fall of argentina s currency board the rise and fall of argentina s currency board shows the extent to which the advantages of hard pegs have been overstated the currency board did provide nominal stability and boosted financial intermediation at the cost of endogenous financial dollarization but did not foster monetary or fiscal discipline the failure to adequately address the currency growth debt trap into which argentina fell at the end of the 1990s precipitated a run on the currency and the banks followed by the abandonment of the currency board and a sovereign debt default the crisis can be best interpreted as a bad outcome of a high stakes strategy to overcome a weak currency problem to increase the credibility of the hard peg the government raised its exit costs which deepened the crisis once exit could no longer be avoided but some alternative exit strategies would have been less destructive than the one adopted

on the effectiveness of exchange rate interventions in emerging markets we analyze the effectiveness of exchange rate interventions for a panel of 18 emerging market economies during the period 2003 2011 using an error correction model approach we find that on average intervention is effective in moving the real exchange rate in the desired direction controlling for deviations from the equilibrium and short term changes in fundamentals and global financial variables our results are robust to different samples and estimation methods we find little evidence of asymmetries in the effect of sales and purchases but some evidence of more effective interventions for large deviations from the equilibrium we also explore differences across countries according to the possible transmission channels and nature of some global shocks

a model of financial crises in emerging markets recent events in mexico asia russia and brazil have underscored that a satisfactory explanation of financial crises in emerging markets remains elusive not too long ago the prevailing view was that crises were the inevitable outcome of ongoing fiscal imbalances coupled with fixed exchange rates but this first generation view pioneered by krugman 1979 has fallen out of fashion because in many crises the crucial fiscal disequilibria were absent and as obstfeld 1994 has argued currency crises have sometimes occurred even though central banks had more than enough resources to prevent them witness much of europe in the early 1990s obstfeld put forward a second generation view in which central banks may decide to abandon an exchange rate peg when the unemployment costs of defending it become too large this new perspective implied that crises could be driven by self fulfilling expectations since the costs of defending the peg may themselves depend on anticipations that the peg will be maintained but obstfeld s emphasis on mounting unemployment and domestic recession while appropriate for the erm 1992 crisis was at odds with the facts in mexico in 1994 and east asia in 1997 asian

a search theoretic approach to monetary economics the essential function of money is its role as a medium of exchange the authors formalize this idea using a search theoretic equilibrium model of the exchange process that captures the double coincidence of wants problem with pure barter one advantage of the framework described here is that it is very tractable the authors also show that the model can be used to addre ss some substantive issues in monetary economics including the potenti al welfare enhancing role of money the interaction between specializat ion and monetary exchange and the possibility of equilibria with multip le fiat currencies copyright 1993 by american economic association

seasonal solow residuals and christmas a case for labor hoarding and increasing returns in aggregate unadjusted data measured solow residuals exhibit large seasonal variations total factor productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of 24 percent how much of the total seasonal variation in the measured solow residual can be explained by christmas the answer to this question is surprising with increasing returns and time varying labor effort christmas is sufficient to explain the seasonal variation in the solow residual consumption average productivity and output in all four quarters our analysis of seasonally unadjusted data uncovers important roles for labor hoarding and increasing returns that are difficult to identify in adjusted data prescott 1986 has argued that the variability of solow s residual is a reasonable estimate of the variability of exogenous technology shocks when solow s residual is measured using seasonally unadjusted data for the postwar u s economy it exhibits large seasonal variations growing rapidly in the fourth quarter at an annual rate of 16 percent and falling sharply in the first quarter at an annual rate of 24 percent this paper starts from the premise that it is implausible to attribute seasonal variation of this magnitude to changes in the state of technology we present a model in which all seasonal fluctuations arise from a single demand shift christmas this demand shift together with misspecification of the traditional production function leads to large seasonal variation in the solow residual we consider two candidates for misspecification labor hoarding and external increasing returns to scale even when technological growth is aseasonal either candidate in isolation can induce spurious seasonality in the solow residual our general equilibrium analysis indicates that 1 the economy s seasonal patterns in all four quarters may be a response simply to a fourth quarter consumption demand shift and 2 a combination of labor hoarding and external increasing returns is important for replicating these patterns in aggregate quantity variables for the postwar u s economy since our analysis identifies important roles for labor hoarding and increasing returns these results have implications for nonseasonal macroeconomic models indeed our analysis im

tax disturbances and real economic activity in the postwar united states abstract this paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates it finds that systematically including tax variables in a standard real business cycle model substantially improves the model s ability to reproduce basic facts about postwar u s business cycle fluctuations in particular modeling fluctuations in personal and corporate income tax rates increases the model s predicted relative variability of hours and decreases its predicted correlation between hours and average productivity fluctuations in tax rates produce large substitution effects that alter the leisure labor supply decision

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

lumpy consumer durables market power and endogenous business cycles in this paper we show that lumpy consumer durables and market power can generate endogenous cycles consistent with the facts past sales determine the current market size of durable goods larger past sales ceteris paribus thus naturally result in a smaller current market size and income in this manner the seeds of a downturn are sown in an upturn jel classification e32 e13 biens de consommation durables en gros morceaux pouvoir de marche et cycles d affaires endogenes ce memoire montre que des biens de consommation durables en gros morceaux et du pouvoir de marche peuvent engendrer des cycles endogenes qui se calquent sur les chroniques observees les ventes passees determinent la taille du marche present pour les biens durables de plus grandes ventes dans le passe toutes choses etant egales par ailleurs resultent naturellement en un marche present plus petit et des revenus moindres de cette maniere le germe du declin est deja contenu dans l expansion

heterogeneity and output fluctuations in a dynamic menu cost economy when firms face menu costs the relation between their output and money is highly non linear at the aggregate level however this needs not be so in this paper we study the dynamic behaviour of a menu cost economy where firms are heterogeneous in the shocks they perceive and the demands and adjustment costs they face in this context we i generalize the caplin and spulber 1987 steady state monetary neutrality result ii show that uniqueness of equilibria depends not only on the degree of strategic complementarities but also on the degree of dispersion of firms positions in their price cycle iii characterize the path of output outside the steady state and show that as strategic complementarities become more important expansions become longer and smoother than contractions and iv show that the potential impact of monetary shocks is an increasing function of the distance of the economy from its steady state but that an uninformed policy maker will have no effect on output on average

earnings quality in uk private firms comparative loss recognition timeliness abstract uk private and public companies face substantially equivalent regulation on auditing accounting standards and taxes we hypothesize that private company financial reporting nevertheless is of lower quality due to different market demand regulation notwithstanding a large uk sample supports this hypothesis quality is operationalized using basu s 1997 time series measure of timely loss recognition and a new accruals based method the result is not affected by controls for size leverage industry membership and auditor size or by allowing endogenous listing choice the result enhances understanding of private companies which are predominant in the economy it also provides insight into the economics of accounting standards

optimal fiscal policy in a business cycle model this paper develops the quantitative implications of optimal fiscal policy in a business cycle model in a stationary equilibrium the ex ante tax rate on capital income is approximately zero there is an equivalence class of ex post capital income tax rates and bond policies that support a given allocation within this class the optimal ex post capital tax rates can range from close to independently and identically distributed to close to a random walk the tax rate on labor income fluctuates very little and inherits the persistence properties of the exogenous shocks thus there is no presumption that optimal labor tax rates follow a random walk most of the welfare gains realized by switching from a tax system like that of the united states to the ramsey system come from an initial period of high taxation on capital income

increasing returns and animal spirits the purpose of this note is to simply point out that the multiplicity intrinsic of course to the presence of non convexities characterizes the models of growth with external increasing returns which have been studied recently and more importantly to show that the many competitive equilibria which often arise in those models can be interpreted as animal spirits equilibria that is equilibria indexed by the consumers optimism or pessimism this multiplicity of competitive equilibrium paths can be viewed as providing a new foundation upon which to build a theory of self fulfilling prophecies one which relies solely on the existence of external effects and does not rest on the overlapping generation structure or on back ward bending offer curves the conclusion that multiple animal spirits competitive equilibria are likely to arise in a model of external increasing returns would survive the generalization of the framework used in this paper to many period environments be they overlapping generation or representative agent infinite horizon structures this abstract was borrowed from another version of this item

implications for gaap from an analysis of positive research in accounting based on extant literature we review the positive theory of gaap the theory predicts that gaap s principal focus is on control performance measurement and stewardship and that verifiability and conservatism are critical features of a gaap shaped by market forces we recognize the advantage of using fair values in circumstances where these are based on observable prices in liquid secondary markets but caution against expanding fair values to financial reporting more generally we conclude that rather than converging u s gaap with ifrs competition between the fasb and the iasb would allow gaap to better respond to market forces

the aggregate implications of machine replacement theory and evidence the authors study an economy in which producers incur resource costs to replace depreciated machines the process of costly replacement and depreciation creates endogenous fluctuations in productivity employment and output of a single producer the authors explore the spillover effects of machine replacement on other sectors of the economy and provide conditions for synchronized machine replacement by multiple independent producers the implications of their model are generally consistent with observed monthly output employment and productivity fluctuations in automobile plants synchronization of retooling across plants within the auto industry is widespread so that the fluctuations observed at the plant level have aggregate implications copyright 1993 by american economic association

stability chaos and multiple attractors a single agent makes a difference abstract this paper provides an example in which a slight behavioral heterogeneity may fundamentally change the dynamical properties of a nonlinear cobweb market with a quadratic cost function and an isoelastic demand function we consider two types of producers cautious adapters and naive optimizers in a market of naive optimizers a single cautious adapter stabilizes the otherwise exploding market in a market of cautious adapters a single naive optimizer may destabilize the market without him there exists at most one periodic attractor in the market but with him there may appear many and even infinitely many coexisting periodic attractors

classifying exchange rate regimes deeds vs words abstract most of the empirical literature on exchange rate regimes uses the imf de jure classification based on the regime announced by the governments despite the recognized inconsistencies between reported and actual policies in many cases to address this problem we construct a de facto classification based on data on exchange rates and international reserves from all imf reporting countries over the period 1974 2000 which we believe provides a meaningful alternative for future empirical work on the topic the classification sheds new light on several stylized facts previously reported in the literature in particular we find that the de facto pegs have remained stable throughout the last decade although an increasing number of them shy away from an explicit commitment to a fixed regime hidden pegs we confirm the hollowing out hypothesis but show that it does not apply to countries with limited access to capital markets we also find that pure floats are associated with only relatively minor nominal exchange rate volatility and that the recent increase in the number of de jure floats goes hand in hand with an increase in the number of de facto dirty floats fear of floating

bias in economic news the reporting of nominal exchange rate behavior in colombia proquest denotes formulae omitted the behavior of the nominal exchange rate ner is regularly reported and commented on in colombian newspapers editorials and op eds however the number and flavor of the news and commentary seem to increase disproportionately during revaluation in contrast to periods of devaluation 1 during the course of a revaluation it is common to read claims not facts in the press of firms and entire industries in distress owing to revaluation and arguments about the benefits of outdated policies such as fixed and multiple exchange rates implemented after 1967 with the enactment of law 444 congreso de colombia 1967 if not a dollarization of the economy 2on one hand many news articles and op ed pieces often maintain that revaluation is devastating for the macroeconomic performance of the country owing to the reduced income for exporters and holders of foreign debt and the subsequent effects on the employment and wages of workers in related industries on the other hand when devaluation occurs little attention is paid in news editorials or op eds there are no complaints addressing the plausible effects of a devaluation such as inflation from higher prices of foreign capital machinery and equipment or imported raw materials this asymmetry in media reporting is hard to understand why would revaluation be more important to report and discuss than devaluation why are there claims of the benefits of a fixed exchange rate when the country has already gone through the crippling effects of an exchange rate black market premium easterly 2002 p 222 describes a high black market premium as a punitive tax on exporters not a good incentive for growth finally why after almost twenty years of experience with a market determined nominal exchange rate is revaluation still reported as harmful for the economy even though there have been more devaluation episodes than revaluation ones 3 one answer to these questions lies in media bias in reporting the behavior of the ner the existence of an interest group supplying media outlets with news to increase the awareness of readers and government officials of the catastrophic consequences of revaluation is considered when this is the case the media benefit from a larger audience and subsequent higher income from advertising revenues the interest group s goal is further satisfied when the fiscal authority offers subsidies or the monetary authority intervenes in the exchange rate market when a government related institution steps in to tame the expressions of discomfort it fulfills the goal of increasing political affection and public acceptance there is a growing literature on the economics of media bias and media slant gentzkow and shapiro 2008 and larcinese puglisi and snyder 2011 offer a review of the theoretical and empirical approaches to this topic the literature describes both supply and demand side models on the supply side the distortions of the news its relationship with the private sector and the government capture of media are the core subjects on the demand side the distortion comes from the public and its preference for news with a certain bias or slant and the media competition for their attention the empirical evidence of media bias shown in this paper fits into the supply side models and the idea of media capture not by the government but by an interest group specifically the work of corneo 2006 is an appropriate analytic framework for the alleged sources of media bias and slant in this paper corneo 2006 builds a voting model of media capture at the hands of special interests to begin with the interest group looking for a policy that will favor its current status seeks to form a coalition with the media the media can accept or refuse the formation of a coalition when they do refuse media demonstrate their independence and commitment to honest reporting

regulating capital flows to emerging markets an externality view abstract we show that capital flows to emerging market economies create externalities that differ by an order of magnitude depending on the state contingent payoff profile of the flows those with pro cyclical payoffs such as foreign currency debt generate substantial negative pecuniary externalities because they lead to large repayments and contractionary exchange rate depreciations during financial crises conversely capital flows with an insurance component such as fdi or equity are largely benign we construct an externality pricing kernel and use sufficient statistics and dsge model simulations to quantify the externalities that materialized during past financial crises we find stark differences depending on the payoff profile justifying taxes of up to 3 for dollar debt but close to zero for fdi these findings contrast with the existing literature which has suggested that policymakers should focus on reducing over borrowing rather than changing the composition of external liabilities

reserve requirements on sovereign debt in the presence of moral hazard on debtors or creditors this paper characterises the effects of reserve requirements on financial loans in the presence of moral hazard on the lender side and sovereign risk on the borrower side the impacts of such reserve requirements on the equilibrium default risk and borrowing are analysed and their welfare implications discussed more generous bailouts financed by the high income block encourage borrowing and increase the probability of default the optimal reserve requirements for both lender and borrower are characterised the

balanced budget rules distortionary taxes and aggregate instability a traditional argument against a balanced budget fiscal policy rule is that it amplifies business cycles by stimulating aggregate demand during booms via tax cuts and higher public expenditures and by reducing demand during recessions through a corresponding fiscal contraction this paper suggests an additional source of instability that may arise from this type of fiscal policy rule it shows that within the standard neoclassical growth model a balanced budget rule can make expectations of higher tax rates self fulfilling if the fiscal authority relies heavily on changes in labor income taxes to eliminate short run fiscal imbalances calibrated versions of the model show that indeterminacy occurs for income tax rates that are empirically plausible for the u s economy and other group of seven countries

conditionally conservative fair value measurements abstract firms measure fair values using level 2 or 3 inputs when items do not trade in liquid markets limiting market discipline over the measurements we provide evidence that firms holding higher proportions of financial instruments measured at level 2 and 3 fair values report more conditionally conservative comprehensive income attributable to fair value measurements consistent with firms trying to mitigate investors discounting of the measurements we further predict and find that this conditional conservatism 1 increases with governance mechanisms that increase the strength and persistence of firms incentives to report conservatively and 2 decreases with firms earnings management incentives

indeterminacy and increasing returns abstract we investigate properties of the one sector growth model with increasing returns under two organizational structures capable of reconciling the existence of aggregate increasing returns with competitive behavior by firms the first involves input externalities the second involves monopolistic competition we show for parameters in close accord with recent literature on real business cycles that the model displays an indeterminate steady state that can be exploited to generate a model of business fluctuations driven by self fulfilling beliefs in our first class of models growth is generated by exogenous increases in factor productivity in the second class the marginal product of capital is large enough for endogenous growth journal of economic literature classification numbers e00 e3 o40

discussion of acquisition profitability and timely loss recognition by j francis and x martin abstract francis and martin 2009 test whether accounting conservatism induces managers to make better acquisition decisions this discussion highlights three main issues first the hypothesized links between conservatism and future investments are potentially incomplete in particular the possibility that conservatism can have dysfunctional outcomes if acquisition decisions are based on anticipated earnings effects is ignored second the evidence is insufficient to infer a causal relation between conservatism and acquisition profitability third the hypothesis development fails to indicate whether timely loss recognition or the asymmetric timeliness of loss versus gain recognition is the more appropriate measure of conservatism given the context

liquidity loanable funds and real activity abstract this paper develops a general equilibrium model of two traditional explanations of the monetary black box linking money and real activity the liquidity effect and the loanable funds effect these effects are modeled with a monetary production economy in which central bank injections of cash are funnelled into the economy through the credit market since only borrowers have direct access to the newly injected cash monetary injections cause nominal interest rates to fall if firms are borrowers then monetary injections also increase current and future real activity

real exchange rate policies for economic development abstract this paper analyzes the role of real exchange rate rer policies in promoting economic development markets provide a suboptimal amount of investment in sectors characterized by learning spillovers we show that a stable and competitive rer policy may correct for this externality and other related market failures the resulting development of these sectors leads to overall faster economic growth a system of effectively multiple exchange rates is required when spillovers across different tradable sectors differ the impact of rer policies is increased when they are complemented by traditional industrial policies that increase the elasticity of the aggregate supply to the rer among the instruments required to implement a stable and competitive rer are interventions in the foreign exchange market and regulation of capital flows we also discuss the trade offs associated with alternative stable and competitive rer policies and the relationship between the use of exchange rate policies for macro stability and for development

a new financial order in asia will a rmb bloc emerge abstract the objective of this paper is three fold first the monetary and exchange rate regimes of the asian countries are described and analyzed the degrees of flexibility in exchange rates and capital controls vary across countries some countries have adopted a flexible inflation targeting framework while others have pursued exchange rate targeting the paper presents a new result of a tradeoff between price stability and exchange rate stability in the hyperbolic relationship of asian countries second a framework that analyzes and quantifies the degree of currency internationalization is proposed and applied to the rmb in every indicator the rmb s weight in private sector international finance has grown in the last several years both in the private and public sectors in the settlement role of currency the rmb is ranked 8th in the bis survey and 7th in swift usage this paper exploits data of a recent period when the rmb became de pegged from the usd and show some of the emerging asian currencies co moving with the rmb more so than the usd in the official sector rmb is also increasing its weight the chinese central bank has extended the currency swap agreements with 30 some countries so that the rmb can be used for trade finance and liquidity assistance the rmb is adopted as a composition currency of the special drawing rights sdr effective in october 2016 with 10 92 ranking number 3 surpassing the jpy and gbp finally potential impending changes in the asian monetary and exchange rate regimes in asia are discussed projecting the growth of the chinese economy into the future the weight of the rmb in the financial markets will increase globally as well as in asia

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

exchange rate policies in asia in an era of financial globalisation an empirical assessment ebbs and flows of capital have complicated macroeconomic policy management for all emerging market and developing economies emdes regardless of whether they have adopted flexible or managed exchange rate regimes in the light of the renewed interest in the trilemma versus dilemma debate we contribute to the related literature by presenting an empirical analysis of exchange rate flexibility and intervention for selected asian emdes over the time period 2001 2016 in addition to estimating augmented frankel wei regressions we employ a generalised auto regressive conditional heteroscedasticity garch model to assess the extent of foreign exchange fx intervention and whether there exist any asymmetries in the way countries intervene our results show that although there is greater flexibility in exchange rates there is evidence of some countries potentially using fx intervention to manage currency movements we also find evidence of asymmetry in intervention where exchange rate volatility responds more emphatically to fx sales than purchases

central banks and macroeconomic policy choices relaxing the trilemma abstract macroeconomic policy choices in open economies are constrained by the trilemma according to which the objectives of exchange rate stability monetary independence and capital mobility cannot be attained jointly this paper shows that foreign exchange interventions provide an effective instrument to relax the trilemma an active reserve policy allows central banks to pursue independent monetary and exchange rate policies when the capital account is liberalised we use the framework of the portfolio balance model to show that exchange market interventions may substitute for capital controls both allow a country to achieve the other two objectives of the trilemma our empirical analysis of a large country panel data set covering the period 1970 2010 confirms this theoretical insight the weighted sum of the three trilemma objectives increases in the degree of foreign exchange market intervention the capacity to relax the trilemma constraint has increased over time and has been most effective in emerging markets

hoarding international reserves versus a pigovian tax cum subsidy scheme reflections on the deleveraging crisis of 2008 9 and a cost benefit analysis abstract we outline the case for supporting self insurance by imposing a tax on external borrowing in a model of an emerging market entrepreneurs finance tangible investments via bank intermediation of foreign borrowing exposing the economy to negative fire sale externalities at times of deleveraging a risk that increases with the ratio of aggregate external borrowing to international reserves price taking economic agents ignore their marginal impact on the expected cost of a deleveraging crisis the optimal borrowing tax reduces the distorted activity external borrowing and induces borrowers to co finance the precautionary hoarding of international reserves

understanding discretion in conservatism an alternative viewpoint various studies have investigated variation in reporting conservatism with pre specified contractual incentives lawrence et al forthcoming hereafter lss propose a model to control for normal or non discretionary conservatism while testing for variation in conservatism with contractual forces which they characterize as discretionary variation our objective is to further the discussion on discretion in conservatism by relying on lss and incorporating insights from related studies to shed light on the rationales and relative importance of various controls for normal conservatism suggested by lss furthermore our perspective on discretion in conservatism is distinct from the one developed by lss in some crucial respects ultimately leading us to question the nature of the boundary between discretionary and non discretionary conservatism

equilibrium selection in imperfectly competitive economies with multiple equilibria this paper investigates the selection of an equilibrium in an economy with multiple pareto ranked nash equilibria a history dependent selection criterion is proposed which induces correlated behavior in equilibrium even though agents are playing one shot games and disturbances are not correlated over time the model economy may experience prolonged periods in which a low productivity technology is in use and then as a consequence of a large real disturbance may switch to an alternative equilibrium in which a high productivity technology is utilized thus the model qualitatively matches observations of serially correlated movements in output and employment and generates procyclical productivity though there are no exogenous technology shocks copyright 1994 by royal economic society

distinguished lecture on economics in government exchange rate regimes is the bipolar view correct the choice of appropriate exchange rate regime which for economies with access to international capital markets increasingly means a move away from the middle ground of pegged but adjustable fixed exchange rates towards the two corner regimes of either flexible exchange rates or a fixed exchange rate supported if necessary by a commitment to give up altogether an independent monetary policy lawrence h summers 2000 p 8

relative price volatility under sudden stops the relevance of balance sheet effects abstract sudden stops are associated with increased volatility in relative prices we introduce a model based on information acquisition to rationalize this increased volatility an empirical analysis of the conditional variance of the wholesale price to consumer price ratio using panel arch techniques confirms the relevance of sudden stops and potential balance sheet effects as key determinants of relative price volatility where balance sheet effects are captured by the interaction of a proxy for potential changes in the real exchange rate linked to the degree of external leverage of the absorption of tradable goods and a measure of domestic liability dollarization

do exchange rate shocks have asymmetric effects on reserve accumulation evidence from emerging markets it is generally argued that central banks in emerging market countries motivated by a desire to defend export competitiveness tend to intervene in foreign exchange markets to limit currency appreciations rather than depreciations using panel data from 13 emerging market countries for the period 1998 m1 to 2016 m12 we find that exchange rate shocks play an important role in determining the accumulation of international reserves moreover we find evidence that central banks in emerging markets tend to follow a leaning against the depreciation wind policy rather than the appreciation wind i e we provide evidence of a fear of depreciation

methodological and empirical issues in real business cycle theory abstract in this paper we argue that the major impact of the rbc literature has been to propose a new methodology for macroeconomics this methodology is distinguished first by the importance it attributes to the empirical description of the phenomena to be explained and second by the use of this description in conjunction with quantitative theorizing i e the construction of computable general equilibrium models whose characteristic statistics match those of the data in accordance with this approach we first report on the current state of knowledge concerning business cycle regularities and conclude that additional empirical effort is called for in order to arrive at the appropriate basis for theorizing we then examine the performance of existing models and evaluate the case for integrating monetary factors and demand shocks into them lastly we review the recent efforts to explain the employment variability puzzle and argue that the search for a solution naturally leads to the incorporation of significant non walrasian features into the rbc framework

reserve accumulation and financial crises from individual protection to systemic risk abstract this paper provides a new perspective on the relationship between countries international reserve holdings and financial crises while the local view holds that reserves may prevent domestic crises it overlooks that the accumulation of reserves relaxes the financing constraint of the reserve currency country and may cause a financial crisis in the centre which is transmitted globally according to this global view reserve accumulation might destabilize the international financial system since the crisis affects all countries alike the accumulation of reserves imposes a negative externality on non accumulating countries we integrate this idea in a theoretical model of the optimal amount of reserves and illustrate the gap between local and global optimality the consideration of systemic risk lowers the demand for reserves moreover if a supranational authority determines the optimal level of reserves it internalizes the negative externality and accumulates fewer reserves a macroprudential tax on reserve hoardings might implement the socially optimal solution our calibration analysis shows that these considerations are economically significant they lower the optimal amount of reserves in the benchmark case by 45

asynchronized multiperiod commitments and cycles abstract we consider a game where agents can synchronize or stagger their decisions we compare the outcomes of both timing patterns and show that spillovers and strategic interactions are crucial for such a comparison a typology used in industrial organization distinguishing four cases fat cat top dog lean and hungry puppy dog allows us to compare the actions taken in the staggered variant and in the synchronized one the staggered variant exhibits cycles and players are both better off when there are strategic complementarities between them a timing game is then set up so as to endogenize the choice between the two variants we study two examples are developed i bertrand competition and ii a wage setting game when there are two monopoly unions in two interrelated firms we show that the staggering of price decisions generates counter cyclical mark ups in the first example and the staggering of wage decisions generates cycling output in the industry in the second example

in defense of fair value weighing the evidence on earnings management and asset securitizations abstract dechow myers and shakespeare dms 2009 find a negative relation between income from securitization activities and income from non securitization activities dms interprets this finding as indicating that managers use the flexibility available in fair value accounting rules to smooth earnings we clarify the role of fair value in accounting for asset securitizations discuss alternative explanations for the evidence presented in dms and offer suggestions for future research we caution against inferring the desirability of any particular accounting method from earnings management research

microeconomic adjustment hazards and aggregate dynamics the basic premise of this paper is that understanding aggregate dynamics requires considering that agents are heterogeneous and that they do not adjust continuously to the shocks they perceive we provide a general characterization of lumpy behavior at the microeconomic level in terms of an adjustment hazard function which relates the probability that a unit adjusts to the deviation of its state variable from its moving target we characterize rich cross sectionally dependent aggregate dynamics generated by nonconstant hazards we present an example based on u s manufacturing employment and job flows and find that increasinghazard models outperform constant hazard partial adjustment models in describing aggregate employment dynamics

a corporate balance sheet approach to currency crises this paper presents a general equilibrium currency crisis model of the third generation in which the possibility of currency crises is driven by the interplay between private firms credit constraints and nominal price rigidities despite our emphasis on microfoundations the model remains sufficiently simple that the policy analysis can be conducted graphically the analysis hinges on four main features i ex post deviations from purchasing power parity ii credit constraints a la bernanke gertler iii foreign currency borrowing by domestic firms iv a competitive banking sector lending to firms and holding reserves and a monetary policy conducted either through open market operations or short term lending facilities we derive sufficient conditions for the existence of a sunspot equilibrium with currency crises we show that an interest rate increase intended to support the currency in a crisis may not be effective but that a relaxation of short term lending facilities can make this policy effective by attenuating the rise in interest rates relevant to firms

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

aggregation and optimization with state dependent pricing the literature on the aggregation of s s policies has ignored the impact of aggregate behavior on the individual s optimization problem in the case of pricing the feedback effects are clear not only do pricing strategies determine the evolution of the price level but the evolution of the price level also influences the optimal pricing strategies in this paper we provide a consistent treatment of aggregation and optimization we use this model to analyze three issues in the menu cost pricing literature the relationship between strategic complementarity and the real effects of money the relationship between the variance of the money supply and the correlation between money and output and the relationship between the cost of price adjustment and the size of price adjustment questions concerning the dynamics of aggregate variables such as prices employment investment and consumption represent the core of business cycle analysis one striking feature of these variables is the radical difference between properties of these aggregates and the nature of the individual behavior that underlies them the behavior of a firm s prices investment and employment and the behavior of an individual s consumption all involve frictional elements that lead to discrete adjustment at the microeconomic level heterogeneity among individuals however tends to smooth the behavior of the corresponding aggregates in recent years a large body of research has developed to examine the manner in which microeconomic frictions influence aggregate dynamics one of the centerpieces of this research has been the s s model developed by arrow harris and marschak 1951 the key element of this model is the state dependence of individual decisions agents act when a state variable crosses some critical threshold which balances the cost and benefits of adjustment the aggregate implications of this form of microeconomic behavior have been analyzed by blinder 1981 caplin 1985 and mosser 1991 in the context of inventory dynamics by caplin and spulber 1987 caballero and engel 1991 1993 and caplin and leahy 1991 in the context of prices and by bertola and caballero 1990 caballero 1993 and eberly 1994 in the context of con sumer durables one of the most limiting aspects of these models is that they focus exclusively on the impact that microeconomic inertia has on aggregate dynamics they 1we would like to thank michael harrison loannis karatzas john leahy sr andreu mas colell a co editor and four anonymous referees for helpful discussions and comments and the national science foundation and the sloan foundation for financial support

a stable international monetary system emerges inflation targeting is bretton woods reversed a stable international monetary system has emerged since the early 1990s a large number of industrial and a growing number of developing countries now have domestic inflation targets administered by independent and transparent central banks these countries place few restrictions on capital mobility and allow their exchange rates to float the domestic focus of monetary policy in these countries does not have any obvious international cost inflation targeters have lower exchange rate volatility and less frequent sudden stops of capital flows than similar countries that do not target inflation inflation targeting countries also do not have current accounts or international reserves that look different from other countries this system was not planned and does not rely on international coordination there is no role for a center country the imf or gold it is durable in contrast to other monetary regimes no country has been forced to abandon an inflation targeting regime succinctly it is the diametric opposite of the post war system bretton woods reversed

fear of appreciation abstract in recent years the term fear of floating has been used to describe exchange rate regimes that while officially flexible in practice intervene heavily to avoid sudden or large depreciations however the data reveals that in most cases and increasingly so in the 2000s intervention has been aimed at limiting appreciations rather than depreciations often motivated by the neo mercantilist view of a depreciated real exchange rate as protection for domestic industries as a first step to address the broader question of whether this view delivers on its promise we examine whether this fear of appreciation has a positive impact on growth performance in developing economies we show that depreciated exchange rates indeed lead to higher growth but that the effect rather than through import substitution or export booms as argued by the mercantilist view works largely through the deepening of domestic savings and capital accumulation

fiscal policy in general equilibrium this paper studies four classic fiscal policy experiments within a quantitatively restricted neoclassical model the authors main findings are as follows 1 permanent changes in government purchases can lead to short run and long run output multipliers that exceed one 2 permanent changes in government purchases induce larger effects than temporary changes 3 the financing decision is quantitatively more important than the resource cost of changes in government purchases and 4 public investment has dramatic effects on private output and investment these findings stem from important dynamic interactions of capital and labor absent in earlier equilibrium analyses of fiscal policy copyright 1993 by american economic association

a model of imperfect competition with keynesian features the recent literature on the reappraisal of keynes has viewed keynesian equilibria as arising when prices are fixed and effective demands and supplies are equilibrated through the adjustment of quantities one problem with this approach is that it lacks a theory of price determination in particular of why prices are fixed in the present paper we show that a number of keynesian features arise in a model in which prices are fully flexible but where agents have some monopoly power one advantage of this approach is that it provides a theory of the determination of both prices and quantities

multiple expectational equilibria under monopolistic competition this paper shows that a monopolistically competitive economy with real investment can have multiple rational expectations equilibria one is associated with entrepreneurs optimistic expectations about future demand another with entrepreneurs pessimism it also shows that an optimistic expectational equilibrium pareto dominates a pessimistic equilibrium an investment subsidy can be beneficial both by reducing the original underinvestment distortion and by changing firms expectations from pessimistic to optimistic the most important assumption is increasing returns to scale and monopolistic competition makes increasing returns consistent with each producer s optimization

aid dutch disease and manufacturing growth abstract we examine the effects of aid on the growth of manufacturing using a methodology that exploits the variation within countries and across manufacturing sectors and corrects for possible reverse causality we find that aid inflows have systematic adverse effects on a country s competitiveness as reflected in the lower relative growth rate of exportable industries we provide some evidence suggesting that the channel for these effects is the real exchange rate appreciation caused by aid inflows we conjecture that this may explain in part why it is hard to find robust evidence that foreign aid helps countries grow

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

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

state dependent pricing and the general equilibrium dynamics of money and output economists have long suggested that nominal product prices are changed infrequently because of fixed costs in such a setting optimal price adjustment should depend on the state of the economy yet while widely discussed statedependent pricing has proved difficult to incorporate into macroeconomic models this paper develops a new tractable theoretical state dependent pricing framework we use it to study how optimal pricing depends on the persistence of monetary shocks the elasticities of labor supply and goods demand and the interest sensitivity of money demand

rationalizability learning and equilibrium in games with strategic complementarities we study a rich class of noncooperative games that includes models of oligopoly competition macroeconomic coordination failures arms races bank runs technology adoption and diffusion r d competition pretrial bargaining coordination in teams and many others for all these games the sets of pure strategy nash equilibria correlated equilibria and rationalizable strategies have identical bounds also for a class of models of dynamic adaptive choice behavior that encompasses both best response dynamics and bayesian learning the players choices lie eventually within the same bounds these bounds are shown to vary monotonically with certain exogenous parameters we study the class of noncooperative supermodular games introduced by topkis 1979 and further analyzed by vives 1985 1989 who also pointed out the importance of these games in industrial economics supermodular games are games in which each player s strategy set is partially ordered the marginal returns to increasing one s strategy rise with increases in the competitors strategies so that the game exhibits strategic complementarity 2 and if a player s strategies are multidimensional marginal returns to any one com ponent of the player s strategy rise with increases in the other components this class turns out to encompass many of the most important economic applications of noncooperative game theory in macroeconomics diamond s 1982 search model and bryant s 1983 1984 rational expectations models can be represented as supermodular games in each of these models more activity by some members of the economy raises the returns to increased levels of activity by others in oligopoly theory some models of bertrand oligopoly with differentiated products qualify as supermodu lar games in these games when a firm s competitors raise their prices the marginal profitability of the firm s own price increase rises a similar structure is present in games of new technology adoption such as those of dybvig and spatt 1983 farrell and saloner 1986 and katz and shapiro 1986 when more users hook into a communication system or more manufacturers adopt an interface standard the marginal return to others of doing the same often rises similarly in some specifications of the bank runs model introduced by diamond and dybvig 1983 when more depositors withdraw their funds from a bank it is more worthwhile for other depositors to do the same in the warrant exercise

real business cycles and the animal spirits hypothesis abstract we calibrate a quantitative equilibrium macroeconomic model with an aggregate technology that is subject to increasing returns and show that this model may display fluctuations at business cycle frequencies even when there are no shocks to the fundamentals of the economy these fluctuations are due to the self fulfilling beliefs of investors which we call animal spirits we compare the impulse response functions predicted by our model and by two other more standard models with a four variable vector autoregression on u s data our animal spirits economy is the most successful of the three at matching broad features of the dynamic responses in the data journal of economic literature classification numbers e00 e3 e32

the recent growth of international reserves in developing economies a monetary perspective abstract the massive accumulation of international reserves in developing economies is a puzzling recent development in the world economy this paper studies reserve accumulation as the outcome of a simple model in which the central bank smooths inflation i explore the view that central banks accumulate reserves to face large fiscal shocks that need monetary financing central bank revenues are obtained through inflation but inflation is distortionary as a result the central bank optimally accumulates international reserves in order to spread the costs associated with inflation over time a simple numerical exercise for an average developing economy using data between 1970 and 2009 yields fast growth of international reserves

stochastic fiscal policy and the swedish business cycle in this paper we show that fluctuations in distortive taxes can account for some of the key features of the swedish post war business cycle the empirical fit of a simple stochastic growth model is significantly improved when it is amended to include imperfectly predictable fluctuations in payroll taxes consumption taxes and government consumption indeed using the simulated method of moments smm we find that for large sets of conventional moments models with stochastic fiscal policy cannot be statistically rejected whereas a model without it is always rejected

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed
