the classification and performance of alternative exchange rate systems abstract owing to dissatisfaction with the imf s de jure classification of exchange rate regimes a substantial literature has emerged presenting de facto classifications of exchange rate systems and using the latter classifications to compare performances of alternative regimes in terms of key macroeconomic variables this paper critically reviews the literature on de facto regimes in particular the paper 1 describes the main methodologies that have been used to construct de facto codings 2 surveys the empirical literature generated by de facto regime codings and 3 lays out the problems inherent in constructing de facto classifications the empirical literature is found to yield few robust findings we argue that the as yet unfulfilled objective of this literature and the major research agenda for the future in this area lies in the need of a more thorough investigation of the degree of monetary policy independence without relying exclusively on movements in exchange rates an agenda the attainment of which is made especially challenging because of the lack of comprehensive and reliable data on reserves and interest rates

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

inflation targeting and fear of floating in brazil mexico and south korea we present evidence on fear of floating ff practices before and after the adoption of inflation targeting it for three emerging countries that faced important exchange rate crises in the 1990 s brazil mexico and south korea we start using the methodologies proposed by calvo and reinhart 2002 and ball and reyes 2008 and check the probabilities of observing small monthly exchange rate changes combined with large movements in policy instruments international reserves and interest rates which should indicate some degree of exchange rate targeting this initial exercise suggests a progress towards greater exchange rate flexibility after it we then use a var model to analyse the monetary policy response to exchange rate and inflation shocks and detect a drastic reduction in direct intervention in the foreign exchange market after it accompanied by a stronger response to inflation these findings are consistent with the it framework and suggest a reduced role for ff

can asia overcome the imf stigma asian countries still have the imf stigma which originates from the experiences of the asian crisis of 1997 98 the feeling of being unfairly treated grew even stronger afterward the asian countries built large foreign reserves carried out structural reforms and became even stronger than pre crisis period asians are confident in not repeating the same mistake of falling into a crisis with too much external borrowing whether imf can entice asia to new precautionary liquidities facilities remains uncertain asia may choose either to focus on completing a regional safety net or to engage in imf demanding for a greater voice and votes

exchange rate policy for developing countries according to the imf in the mid 1970 s approximately 85 percent of developing countries had pegged exchange rate arrangements since then the situation has changed drastically today most developing countries have either managed floats or flexible exchange rates argentina hong kong and a few others may persevere with their currency boards additional nations may well imitate them and movements toward common currencies a la the european union may gain strength here and there nonetheless it seems clear that the political and financial prerequisites to adopt such hard pegs are extremely stringent new attempts are the exception not the rule the question for most emerging market economies is no longer to float or not to float but how to float in this note we review some key issues in defining the right answer to this question

de facto exchange rate regimes and currency crises are pegged regimes with capital account liberalization really more prone to speculative attacks abstract this paper empirically examines whether de facto exchange rate regimes affect the occurrence of currency crises in 84 countries over the 1980 2001 period by using the probit model we employ the de facto classification of reinhart and rogoff 2004 that allows us to estimate the impact of relatively long lived exchange rate regimes on currency crises with much greater precision we find that pegged regimes significantly decrease the likelihood of currency crises compared with floating regimes by using the combined data of exchange rate regimes and the existence of capital controls we also find interesting evidence that pegged regimes with capital account liberalization significantly lower the likelihood of currency crises compared with other regimes these results are robust to a wide variety of samples and models from the standpoint of the macroeconomic policy trilemma we can conjecture that pegged regimes with capital account liberalization are substantially less prone to speculative attacks because they can enhance greater credibility in their currencies by abandoning monetary policy autonomy

the economics of exchange rate regimes a review essay the exchange rate regime issue has taken centre stage in discussions of international economic policy much of the profession appears to have been converted to the hypothesis of the vanishing middle regime for countries well integrated into world capital markets there is little if any middle ground between floating exchange rates and monetary unification this paper considers the exchange rate regime issue in the context of recent books on the subject by w max corden and morris goldstein both authors prescribe managed floating exchange rates supplemented with inflation targeting for emerging market economies under managed floating and with a credible monetary policy the public finances in order and strengthened debt management and prudential regulation the exchange rate is free to act as a market gauge for assessing policies and as a mode of conflict resolution both authors also argue however that no exchange rate regime is a holy grail ultimately a credible exchange rate regime depends upon the trust evoked by governments there is no exchange rate regime whether of the managed floating or hard fix variety that can eradicate a history of failed stabilisation attempts

intertemporal labor supply and long term employment contracts the authors compare the implications of a symmetric information contracting model and a dynamic labor supply model for changes in earnings and hours a simple test is whether earnings changes are more variable than hours changes as predicted by the labor supply model or less variable as predicted by the contracting model the authors apply this test to two longitudinal surveys of adult men and find that earnings are somewhat more variable than hours for men who never change employers the estimates suggest that changes in earnings and hours not associated with survey measurement error occur at fixed wage rates copyright 1987 by american economic association

self enforcing employment contracts and business cycle fluctuations abstract this paper incorporates risk sharing employment contracts into an economy in which matching frictions characterize the labour market and in which agents cannot commit in equilibrium the terms of ongoing contracts are affected by those being negotiated in the job market because contracts must be self enforcing in this context risk sharing implies that hours worked and wages are negatively related while enforcement considerations imply the converse overall the sign of this relationship is ambiguous therefore the existence of such contracts may explain why movements in hours worked appear weakly related to those in real wages in u s aggregate data

the 2009 recovery act stimulus at the extensive and intensive labor margins abstract this paper studies the effect of government stimulus spending on a novel aspect of the labor market the differential impact of spending on the total wage bill versus employment we analyze the 2009 recovery act via instrumental variables using a new instrument the spending done by federal agencies that were not instructed to target funds towards harder hit regions we find a moderate positive effect on jobs created saved i e the extensive margin and also a significant increase in wage payments to workers whose job status was safe without recovery act funds i e the intensive margin our point estimates imply that roughly one half of the wage payments resulting from the act were paid at the intensive margin to provide a theoretical underpinning for the estimates we build a micro founded dynamic model in which a firm meets new government demand with a combination of new hiring and increasing existing workers average hours faced with hiring costs and an overtime premium the firm responds by increasing hours along both margins our model analysis also provides insight into how government spending policy should be structured to lower the cost of generating new jobs finally we catalogue survey evidence from recovery act fund recipients that reinforces the importance of the intensive labor margin

time deposits dimensions and fraud we stipulate arguendo that fractional reserve demand deposit banking is per se fraudulent we ask whether or not time deposit banking can also be illicit and answer in the positive if there is a mismatch between the time dimensions of deposits and loans to wit if an intermediary borrows short and lends long

constraints on exchange rate flexibility in transition economies a meta regression analysis of exchange rate pass through this article uses meta regression analysis mra to investigate exchange rate pass through to domestic prices highlighting differences between transition and developed economies a total of 23 studies yielded 575 coefficients measuring exchange rate pass through to import prices and consumer prices for 23 developed and 12 transition economies the mra results confirm the finding of many particular analyses that exchange rate pass through is less than complete in addition exchange rate pass through is higher to import prices than to consumer prices and exchange rate pass through is higher in the long run than in the short run regarding transition and developed economies mra suggests that there is no statistically significant difference in exchange rate pass through to import prices yet exchange rate pass through to consumer prices is significantly and substantially higher in transition than in developed economies this finding is consistent with the caution of many monetary authorities in transitio

crises and exchange rate regimes time to break down the bipolar view we revisit the link between crises and exchange rate regimes err using a panel of 90 developed and developing countries over the period 1980 2009 we find that corner err are not more prone to crises compared to intermediate err this finding holds for different types of crises banking currency and debt and is robust to a wide set of alternative specifications consequently we clearly break down the traditional bipolar view countries that aim at preventing crisis episodes should focus less on the choice of the err and instead implement sound structural macroeconomic policies

capital markets and the exchange rate with special reference to the dollarization debate in latin america the paper reviews the main challenges faced by policymakers in emerging market economies em in light of recent financial crises and taking into account salient factors like the existence of partial dollarization imperfect credibility weak financial systems and contagion the standard theory of optimal currency areas is discussed and criticized for omitting the above factors when these factors are taken into account an extreme foreign exchange regime like dollarization is shown to become much more attractive the paper discusses the pros and cons of dollarization and among other things shows that the lack of a lender of last resort is not necessarily a major drawback in em the paper also discusses inflation targeting it in a formal model it is shown that it could be subject to credibility problems similar to those found in exchange rate based stabilization programs

macroeconomic policies and performance in latin america abstract this paper provides new evidence on macroeconomic policies and results in latin america and the caribbean results are i credibility allows adoption of counter cyclical macroeconomic policies ii accuracy in meeting inflation targets depends on central bank independence and country risk iii intermediate exchange rate er regimes have become less persistent iv er regimes matter for inflation and growth v real er trends are not explained by productivity growth and supply reforms do not resolve real er misalignments vi financial integration has increased significantly vii foreign shocks are a major growth determinant and viii composition of foreign capital inflows matters for growth

does speed kill lending booms and their consequences in croatia abstract recent research connects lending booms with increased risks of banking and currency crisis another strand of literature connects financial deepening with long term growth together these findings pose dilemmas for policymakers in the case of croatia we find that rapid loan growth increased the probability of credit quality deterioration and stimulated current account and foreign debt problems conventional monetary tightening was not very effective due to capital inflows unconventional measures such as capital controls also had limited effectiveness we propose limiting negative impacts by pro active monetary policy more restrictive fiscal policy and increased capital requirements for fast growing banks rather than measures to prevent lending booms ex ante

welfare cost of fluctuations when labor market search interacts with financial frictions we provide a quantitative assessment of welfare costs of fluctuations in a search model with financial frictions the matching process in the labor market leads positive shocks to reduce unemployment less than negative shocks increase it we show that the magnitude of this non linearity is magnified frictions this asymmetric effect of the business cycle leads to sizable welfare costs the model also accounts for the responsiveness of the job finding rate to the business cycle as financial frictions endogenously generate counter cyclical opportunity costs of opening a vacancy and wage sluggishness

fractional reserve banking client collaboration and fraud this paper traces the recent debate over the legitimacy of maturity mismatching and fractional reserve banking it shows that there is common ground between bagus and howden journal of business ethics 90 3 399 406 2009 106 295 300 2012 on the one hand and evans journal of business ethics 2013 on the other regarding contractual arrangements that lead to fractional reserve banking while both agree that fractional reserve banking that arises out of a bailment or storage contract constitutes fraud block and barnett journal of business ethics 88 4 711 716 2009 100 229 238 2011 stress the illegitimacy of fractional reserve banking for creating more money substitutes than there is actual money while it is true that fractional reserve banks are capable of creating money this activity still cannot be regarded as fraudulent using a common law definition of fraud for it can only take place with requisite client collaboration that makes it impossible to identify a victim

the exchange rate regime and the currency composition of corporate debt the mexican experience abstract this paper analyzes the effect that the change from a fixed to a floating exchange rate regime that took place in mexico in december 1994 had on the currency composition of corporate debt in particular the paper asks whether a fixed exchange rate regime biases corporate borrowing towards foreign currency due to an implicit exchange rate guarantee given by the government therefore under a predetermined regime firms will not fully internalize their exchange rate risk and will be more likely to engage in balance sheet mismatches than under a floating regime we study the main determinants of foreign currency borrowing of those firms listed in the mexican stock exchange from 1992 to 2000 to test whether balance sheet currency mismatches fell after the adoption of the floating exchange rate regime the results found support the view that the floating exchange rate regime has been useful in reducing exchange rate exposure

real wages over the business cycle evidence from panel data one topic on which keynes did not disagree with classical economists was the cyclical behavior of real wages keynes 1936 as well as various classical writers predicted that real wages should move countercyclically quoting the general theory p 17 in general an increase in employment can only occur through the accompaniment of a decline in real wages thus i am not disputing this vital fact which the classical economists have rightly asserted as indefeasible this prediction is based on the premise of competition and a given short run capital stock increases in employment then correspond to more intensive use of capital and through diminishing product lower real wages for this reason evidence by dunlop 1938 and tarshis 1939 that real wages move procyclically was viewed as paradoxical both dunlop and tarshis based their findings on an observed positive correlation between real and money wages which given the procyclical movement of money wages implies a positive correlation between

why did argentina s currency board collapse this paper sheds light on the risks associated with currency board arrangements referring to the severe liquidity crisis that emerged in argentina in november 2000 the inability of the argentinean economy to grow because of an overvalued peso and the massive borrowing needs of the government in the context of rapidly rising borrowing costs seriously undermined the credibility of the fixed exchange rate regime given the widespread dollarisation of the financial sector on the liability side argentina had arguably little choice but to stick to the currency board a series of measures aimed at reviving growth were implemented but with no signs of upturn in demand increasingly distrustful international investors and growing social unrest the country was forced into default in december 2001 putting an abrupt end to its decade long experiment with hard money this study shows that with rigid labour markets a lack of fiscal discipline and the absence of a natural anchor currency argentina was never a strong candidate for a hard peg

international financial crises causes prevention and cures dale jorgenson has bestowed a great honor and no small challenge by inviting me to give this lecture a great honor because of the distinguished list of economists who have preceded me a challenge because of the standard they have set and because there is no greater challenge for any economist than providing a coherent account of significant events to his scientific peers i am sometimes asked by friends about the differences between academic life and life as a public official there are many two stand out first as an academic the gravest sin one can commit is to sign one s name to something one did not write as a public official it is a mark of effectiveness to do so as often as possible second as an academic if a problem is too hard and does not admit of a satisfactory solution there is an obvious response work on a different problem that is not a luxury that one has in government i have been reminded of this often in recent years as we have grappled with financial crises in a number of what had previously been considered emerging markets with unrestrained futures anyone who doubts the social importance of what economists do should consider the debates surrounding these crises hundreds of millions of people who expected rapidly rising standards of living have seen their living standards fall hundreds of thousands if not millions of children have been forced to drop out of school and go to work hundreds of billions of dollars of apparent wealth has been lost the stability of large nations as nations has been called into question and the united states has made its largest nonmilitary foreign policyrelated financial commitments since the marshall plan almost all the issues involved in understanding preventing and mitigating these crises are the stuff of economics courses and research fixed versus flexible exchange rates moral hazard and multiple equilibria speculation and liquidity fiscal and monetary policies regulation and competition what economists think say and do has profound implications for the lives of literally billions of their fellow citizens whether it is discussing the role of derivatives in signaling exchange rate commitments with chinese premier zhu rongji or discussing an nber working paper on inflation targeting with the brazilian central bank governor arminio fraga or discussing alternative approaches to bankruptcy law with indonesia s economic team or optimal debt durations with the mexican authorities i am consistently struck by the impact of the kind of research discussed at the aea meetings the future well being of the world s people in large part will depend on how the ongoing process of global integration works out this is a strong statement but one that is supported by the global economy s post world war i failure and its post world war ii success central to global integration is financial integration the flow of funds and of capital across international borders and as the events of the late 1920 s and early 1930 s remind us central to global disintegration can be international financial breakdowns today i want to reflect on the issue of global financial integration in light of the dramatic and largely unpredicted events of recent years it is perhaps a good time for reflection there has been enough repair that priority can shift from u s department of the treasury 1500 pennsylvania avenue washington dc 20005 this lecture reflects many things i have learned from experiences i have shared with colleagues in the united states government and governments around the world i thank brad delong marty feldstein stephanie flanders ken rogoff andrei shleifer and ted truman for useful comments and suggestions i am especially grateful to nouriel roubini and stephanie flanders for valuable discussions and assistance in the preparation of this lecture the usual disclaimer applies

the welfare cost of business cycles revisited finite lives and cyclical variation in idiosyncratic risk abstract this paper investigates the welfare costs of business cycles in a heterogeneous agent overlapping generations economy which is distinguished by idiosyncratic labor market risk aggregate variation arises both in terms of aggregate productivity shocks and countercyclical variation in the volatility of idiosyncratic shocks based on both aggregate data and microeconomic data from the panel study on income dynamics we find the welfare benefits of eliminating aggregate variation to be large an order of magnitude larger than those originally documented by lucas 1987 the key difference is countercyclical variation in idiosycratic risk which both amplifies the welfare cost of aggregate productivity shocks and imposes a cost of its own the magnitude of these effects increases non linearly in risk aversion our results therefore are consistent with the increasingly popular notion that distributional effects are an important aspect of understanding the welfare cost of business cycles

how effective are capital controls a number of authors have recently argued that in order to avoid financial instability emerging countries should rely on capital controls two type of controls have been considered controls on capital outflows and controls on capital inflows in this paper i review the historical evidence on the effectiveness of these two type of controls i argue that controls on outflows have been ineffective they are circumvented and breed corruption i also analyze chile s recent experience with controls on inflows and i argue that their effectiveness has been exaggerated

monetary convergence of the eu accession countries to the eurozone a theoretical framework and policy implications abstract a flexible approach to direct inflation targeting offers the european union accession countries a viable monetary policy choice that is believed to facilitate both the economic transition and the monetary convergence to the eurozone following this assumption a model investigating the nexus between inflation and selected monetary variables in three eu accession countries the czech republic poland and hungary is advanced the empirical analysis is aimed at explaining the sensitivity of the cpi based inflation path in these countries to backward as well as forward looking expectations nominal exchange rate fluctuations the eurozone inflation impulses and output changes the analysis implies that the monetary convergence begins with flexible inflation targeting and concludes with a full fledged euroization

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

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

individual consumption risk and the welfare cost of business cycles we measure the welfare gain from removing aggregate consumption fluctuations in a model where each individual faces incomplete consumption insurance we show that because this welfare gain is a convex function of the overall consumption risk aggregate plus idiosyncratic each individual faces to gauge the magnitude of the gain it is important to match individuals overall risk prior to any policy in an economy calibrated to match individuals overall risk even removing 10 percent of aggregate fluctuations can result in a large welfare gain further large gains do not necessarily depend on the countercyclical nature of idiosyncratic risk jel e21 e32

exchange rate regimes in developing and emerging economies and the incidence of imf programs summary the global economic crisis will compel many countries to revise key economic policies including their exchange rate regime the international monetary fund will have significant influence on their choices and has exhibited a bias against intermediate regimes we examine the link between exchange rate regimes and imf program use and find no evidence that countries with intermediate exchange rate regimes require more frequent imf assistance rather they appear somewhat less dependent especially when compared to fixed exchange rates our results suggest that intermediate regimes should remain a viable and possibly desirable exchange rate choice for some countries

econometric testing of purchasing power parity in less developed countries fixed and flexible exchange rate regime experiences we investigate the purchasing power parity ppp hypothesis for 16 less developed countries ldcs from all over the world during their fixed and flexible exchange rate experiences over the period 1957 01 1999 12 the main contribution of this article to the empirical literature on ppp is that our study is the first to consider ppp hypothesis on alternative exchange rate regimes for ldcs the bilateral exchange rates of ldcs and the united states and their respective price levels are considered three different time series methodologies are employed unit root tests engle granger 1987 cointegration technique and johansen multivariate var methodology 1988 the cointegration techniques improve the results which allows the examination of the more frequent long run relationship between relative prices and nominal exchange rates nevertheless using each of econometric techniques we find only a few and a nearly equal evidence in favour of ppp under the alternative regimes in ldcs hence the main conc

a theory of wage dynamics a dynamic equilibrium model of long term implicit labour contracts under incomplete but symmetric information is developed workers are assumed to be risk averse and of unknown ability or productivity risk neutral firms learn as do workers about each worker s productivity by observing the worker s output over time it is shown that equilibrium contracts provide for wages which never decline with age and increase only when the worker s market value increases above his current wage in addition to characterizing the equilibrium wage contract we also derive some of its implications for the behaviour of aggregate wages across various groups of workers these implications explain some findings in the recent empirical literature on ageearnings profiles in particular our model can explain why earnings may be positively related to experience even after controlling for productivity as some empirical studies have indicated

endogenous changes in the exchange rate regime a bureaucratic incentive model public choice submits that legal changes can be endogenous in such a way that they are manipulated by bureaucrats who want to maximize rents from transactions with various interest groups this paper takes the change in exchange rate regimes to empirically examine the premise it offers a two stage method in which we first show that the exchange rate is influenced by interest group pressures and subsequently that the 1990 market average regime mar as a phase in policy in korea was introduced mainly to serve bureaucratic incentives this method is expected to be useful to a host of countries for various studies attempting to test a possible existence of bureaucratic or other hidden motivations behind any isolated event of policy change

exchange rate regime durability and performance in developing versus advanced economies abstract drawing on new data and advances in exchange rate regimes classification we find that countries appear to benefit by having increasingly flexible exchange rate systems as they become richer and more financially developed for developing countries with little exposure to international capital markets pegs are notable for their durability and relatively low inflation in contrast for advanced economies floats are distinctly more durable and also appear to be associated with higher growth for emerging markets our results parallel the baxter and stockman classic exchange regime neutrality result though pegs are the least durable and expose countries to higher risk of crisis

monetary policy in emerging markets can liability dollarization explain contractionary devaluations abstract in emerging markets external debt is denominated almost entirely in large developed country currencies such as the u s dollar this liability dollarization offers a channel through which exchange rate variation can lead to business cycle instability when firms assets are denominated in domestic currency and liabilities are denominated in foreign currency an exchange rate depreciation worsens firms balance sheets which leads to higher capital costs and contractions in capital spending to illustrate this i construct a quantitative sticky price small open economy model in which a monetary policy induced devaluation leads to a persistent contraction in output in this model fixed exchange rates offer greater stability than an interest rule that targets inflation

is the behavior of hours worked consistent with implicit contract theory this paper examines the determinants of hours worked when employment relationships are influenced by risk sharing considerations the environment considered is an extension of the standard symmetric information risk sharing model that allows for the possibility of enforcement problems on the part of both the employer and the employee we show that this class of risk sharing models unambiguously predicts hours to be influenced by wages only through an income effect using data from the psed we find evidence in favor of this extended version of the risk sharing model

the effect of implicit contracts on the movement of wages over the business cycle evidence from micro data in this paper we address the question of whether wages are affected by labor market conditions in a manner more consistent with a contract approach than with a standard spot market model from a simple implicit contract model we derive implications about the links between wages and past labor market conditions using individual data from the current population survey and the panel study of income dynamics we find that an implicit contract model with costless mobility describes these links better than either a simple spot market model or an implicit contract model with costly mobility

the role of unemployment insurance in an economy with liquidity constraints and moral hazard the potential welfare benefits of unemployment insurance along with the optimal replacement ratio are studied using a quantitative dynamic general equilibrium model to provide a role for unemployment insurance agents in our economy face exogenous idiosyncratic employment shocks and are unable to borrow or insure themselves through private markets in the absence of moral hazard replacement ratios as high as 65 are optimal and the welfare benefits of unemployment insurance are quite large however if there is moral hazard and the replacement ratio is not set optimally but is instead set to an empirically plausible value the economy can be much worse off than it would be without unemployment insurance

stuck on gold real exchange rate volatility and the rise and fall of the gold standard 1875 1939 abstract did the gold standard diminish macroeconomic volatility supporters thought so critics thought not and theory offers ambiguous messages hard regimes like the gold standard limit monetary shocks by tying policymakers hands but exchange rate inflexibility compromises shock absorption in a world of real disturbances and nominal stickiness a model shows how lack of flexibility affects the transmission of terms of trade shocks evidence from the late nineteenth and early twentieth century exposes a dramatic change the classical gold standard did absorb shocks but the interwar gold standard did not supporting the view that the interwar gold standard was a poor regime choice

implicit bands in the yen dollar exchange rate this article attempts to identify implicit exchange rate regimes for the yen dollar exchange rate to that end we apply a sequential procedure that considers both the dynamics of exchange rates and central bank interventions to data covering the period from 1971 to 2003 our results suggest that implicit bands existed in two subperiods april december 1980 and march october 1987 the latter coinciding with the louvre accord furthermore the study of the credibility of such implicit bands indicates the high degree of confidence attributed by economic agents to the evolution of the yen dollar exchange rate within the detected implicit band rate thus lending further support to the relevance of such implicit bands

embodied technical change and the fluctuations of unemployment and wages a matching model where technological change is partially embodied in the job match is shown to be successful in explaining the variability of unemployment and vacancies if we incorporate long term wage contracts into the model it also explains a number of stylized facts on the dynamics of real wages which have been found in the empirical labor literature

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

foreign exchange intervention in emerging markets a survey of empirical studies nowadays foreign exchange interventions occur in emerging market economies whereas empirical studies on interventions mainly refer to advanced economies however interventions in emerging markets are different from those in advanced economies they occur regularly and central banks have considerable leverage derived from relatively high reserves some non sterilisation the central bank s information advantage and capital controls consequently these interventions often successfully impact the level and volatility of exchange rates nevertheless more research on interventions in emerging markets is needed analysing the influence of heterogeneous institutional circumstances examining the role of central bank communication and using high frequency data

when do governments improve fiscal institutions lessons from financial crisis and fiscal reform in latin america do crises really lead to more institutional reforms this paper explores the connection between financial crises and one type of reform frequently advocated during the recent global financial crisis namely fiscal institutional reforms some authors expect that crises lead to reforms but we demonstrate that the relationship is not so straightforward using a data set of latin american countries that experienced several crises and also several periods of reform in the period from 1990 to 2005 we find that the type of crisis and its duration matter we argue that reforms are less likely during a banking crisis whereas fiscal crises are most likely to lead to fiscal reforms this means that the type of economic crisis is important for explaining the likelihood of reforms we explore other possible explanations for reform such as the partisanship of the president and whether a country is under an imf program and do not find confirming evidence for alternative explanations

identifying monetary policy in a small open economy under flexible exchange rates abstract previous empirical study on the effects of monetary policy shocks in small open economies has generated puzzling dynamic responses in various macroeconomic variables this paper argues that these puzzles derive from an identification of monetary policy that is inappropriate for such economies to remedy this it is proposed that a structural model be estimated to explicitly account for the features of the small open economy such a model is applied to canada with tightly estimated results overall the dynamic responses to the identified monetary policy shock are consistent with standard theory and highlight the exchange rate as a transmission mechanism

on the necessary and sufficient conditions for legitimate banking contracts what role do demand deposits serve in the financial system the answer to this simple question has great implications in keeping the legal terms of the contract consistent with the demands of the financial system demand deposits are a perfect monetary substitute since money is only held to hedge against perceived uncertainty in both the timing and magnitude of future expenditures demand deposits are demanded for the same reason from this we derive three main conclusions first a financial contract similar to a demand deposit e g very short term bonds money market mutual funds etc cannot substitute for money second full agreement to a financial contract does not create a perfect substitute for money unless it provides money s two key characteristics on demand and par value redemption finally the demand for fractional reserve demand deposits is fostered by an exogenous source deposit insurance and that demand for a good or service is not a sufficient condition to justify its legality or ethicality

targeting the real exchange rate theory and evidence abstract this paper presents a theoretical and empirical analysis of policies aimed at setting a more depreciated level of the real exchange rate an intertemporal optimizing model suggests that in the absence of changes in fiscal policy a more depreciated level of the real exchange rate can only be attained temporarily this can be achieved by means of higher inflation and or higher real interest rates depending on the degree of capital mobility evidence for brazil chile and colombia supports the model s prediction that undervalued real exchange rates are associated with higher inflation

a theoretical approach to sterilized foreign exchange intervention in this paper we survey prominent theories that have shaped the literature on sterilized foreign exchange interventions we identify three main strands of literature 1 that which deems interventions futile 2 that which requires some market friction i e limited arbitrage in order for interventions to be effective and 3 that which advocates the use of interventions as long as they convey signals on the stance of future monetary policy we contribute to the literature in three important ways first by reviewing new theoretical models that have surfaced within the last decade second by further penetrating into the theory of interventions in order to analyze the key features that make each model distinct and third by only focusing on sterilized operations which allows us to sidestep the effects induced by changes in the stock of money supply in addition the models that we present comprise both a macro and microstructure approach so as to provide a comprehensive view of the theory behind exchange rate intervention

evaluation of currency regimes the unique role of sudden stops this paper tackles two established puzzles in international macroeconomics literature the first is the lack of systematic differences in the macroeconomic performance across exchange rate regimes the second is the absence of a clear empirical relationship between macroeconomic performance and capital account liberalization we suggest that these negative findings may be due to empirical methods that fail to account for a latent economic crisis state influenced by exchange rate and capital account regimes and to allow that latent variable to influence the growth effects of policy regimes in practice we model and estimate the latent state of the economy as a crisis probability our proposed framework of analysis allows exchange rate and capital market liberalization regimes to have both a direct effect on short term growth and an indirect effect on growth that is channelled through their effects on the crisis probability the empirical decomposition of the total effect into two conflicting effects helps resolve the puzzles assaf razin and yona rubinstein

the time series properties of aggregate consumption implications for the costs of fluctuations the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations this paper pursues two approaches to modeling consumption dynamics and measuring how much society dislikes fluctuations one statistical and one economic the statistical approach estimates the properties of consumption and calculates the costs of having consumption fluctuating around its mean growth the paper finds that persistence is a crucial determinant of the costs and that the high persistence in the data severely distorts conventional measures it shows how to compute valid estimates and confidence intervals the economic approach uses a calibrated model of optimal consumption and measures the costs of eliminating income shocks this uncovers a further cost of uncertainty through its impact on precautionary savings and investment the two approaches lead to costs of fluctuations that are higher than the common wisdom between 0 5 and 5 of per capita consumption jel e32 e21 e60

the un importance of unemployment fluctuations for the welfare cost of business cycles abstract this paper studies the cost of business cycles within a real business cycle model with search and matching frictions in the labor market we endogenously link both the cyclical fluctuations and the mean level of unemployment to the aggregate business cycle risk the key result of the paper is that business cycles are costly fluctuations over the cycle induce a higher average unemployment rate since employment is nonlinear in the job finding rate and the past unemployment rate we show this analytically for a special case of the model we then calibrate the model to u s data for the calibrated model too business cycles cause higher average unemployment the welfare cost of business cycles can easily be an order of magnitude larger than lucas s 1987 estimate the cost of business cycles is the higher the lower the value of nonemployment is or equivalently the lower is the disutility of work the ensuing cost of business cycles rises further when workers skills depreciate during unemployment

explaining the transition between exchange rate regimes this paper studies the transition between exchange rate regimes using a markov chain model with time varying transition probabilities the probabilities are parameterized as nonlinear functions of variables suggested by the currency crisis and optimal currency area literature results using annual data indicate that inflation and to a lesser extent output growth and trade openness help explain the exchange rate regime transition dynamics

low wage employment subsidies versus the welfare state this paper is a brief for the introduction of a subsidy to any qualified firm for its use of low wage employees as a means to reduce the unemployment and raise the pay of disadvantaged workers there would be a case for such a wage subsidy in all the advanced market economies and certainly the american one regardless of recent trends the case has grown stronger however with the worsening of the relative wages and especially the unemployment rates of low age workers the globalization of investment and the bias of technical progress are the causes most often suggested i would add the growth of the welfare system the public entitlements to hospitalization to retirement and disability insurance and to the benefits labeled welfare in the narrow sense since this factor tends to be overlooked i devote section i to it section ii proceeds to the case for a low wage employment subsidy it will be clear that the beneficial effects of the subsidy on disadvantaged workers are the mirror opposite of the harmful side effects of the welfare system side effects that the subsidy would counteract i side effects of the welfare system

inflation targeting in brazil chile and mexico performance credibility and the exchange rate inflation targeting it has been adopted by a growing number of countries and latin america has been part of this world trend this paper reviews the recent it experiences of brazil chile and mexico applying a common empirical framework to the three country cases inflation performance under it and its associated output costs are reported and compared favorably to a control group of other countries the paper analyzes ways by which it has contributed to strengthen credibility the effect of targets on inflation expectations and on actual inflation the low influence of inflation shocks on core inflation and the decline in inflation forecast errors do the three inflation targeters exhibit fear of floating no considering their relatively large exchange rate volatility and moderate international reserve holdings no considering strongly declining inflation to devaluation passthrough coefficients and little evidence for monetary policy reaction to exchange rate shocks yes considering the frequency and intensity of sterilized exchange interventions in comparison to other inflation targeters that float more cleanly

the importance of lifetime jobs in the u s economy though the u s labor market is justly notorious for high turnover and consequent high unemployment it also provides stable near lifetime employment to an important fraction of the labor force this paper investigates patterns of job duration by age race and sex with the following major conclusions 1 the typical worker today is holding a job which has lasted or will last about eight years over a quarter of all workers are holding jobs which will last twenty years or more sixty percent hold jobs which will last five years or more 2 the jobs held by middle aged workers with more than ten years of tenure are extremely stable over the span of a decade only twenty to thirty percent come to an end 3 among workers aged thirty and above about forty percent are currently working in jobs which eventually will last twenty years or more three quarters are in jobs which will last five years or more 4 the duration of employment among blacks is just as long as among whites even though the jobs held by blacks are worse in almost every other dimension they are no more unstable than those held by whites 5 women s jobs are substantially shorter than men s on the average only about a quarter of all women over the age of thirty are employed in jobs which will last over twenty years whereas over half of men over thirty are holding these near lifetime jobs this abstract was borrowed from another version of this item

free banking and monetary control despite growing interest in competitive payments systems and the continuing progress of bank deregulation relatively little is known about the macroeconomic implications of completely unregulated or free banking its advocates view free banking where competing banks freely issue monetary liabilities redeemable in base money 1 as a means for depoliticising the money stock by replacing public holdings of government money with private bank money while limiting changes in the monetary base such a programme begs many crucial questions how would the unregulated stock of bank money be determined would free banking enhance or reduce macroeconomic stability compared to regulated banking what implications would free banking have for the proper conduct of monetary policy lawrence h white i 984 ch i employs a model of a free banking system to answer some of these questions however because it concerns free banklng as practised in scotland in the nineteenth century white s model assumes an open economy operating in an international gold standard where the price level is given and there is no such thing as monetary policy in its modern sense were free banking to reemerge today it would probably be based not on a gold standard but on irredeemable paper fiat base money issued by a former or extant central bank under this form of free banking the price level is no longer given and conventional monetary policy questions remain relevant in particular would free banking on a fiat standard simplify or complicate the control of nominal variables including the price level and nominal income would it be easier or more difficult to adhere to a simple monetary rule what would happen if the stock of base money were frozen as a means for ruling out discretion altogether answers to such questions require an analysis of determinants of the money stock in a closed free banking system with a centrally determined stock of base money here i offer some preliminary answers based upon carl christ s i 989 formal interpretation of selgin i988 the features of free banking stressed here because they bear most on questions of monetary control include i the freedom of banks to issue notes as well as deposits where banknotes are a more

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

does it pay to go to the corners an empirical evaluation of the bipolar view of exchange rate regimes abstract this paper provides the first empirical evidence for the controversial bipolar view which suggests that countries should move towards the two corner regimes my results show that compared to intermediate regimes the two corners are associated with significantly lower inflation

argentina s currency board collapse weak policy or bad luck two basic views can be discerned in post mortems of argentina s currency board 1 that weak fiscal policy was fundamentally to blame and 2 that the peso had become too severely overvalued for the peg to survive this paper evaluates the evidence for these rival interpretations the real effective exchange rate index did not indicate massive overvaluation but this index does not capture the effects on the equilibrium rate of the sudden stop in capital flows to emerging markets after 1998 it also understates the amount of adjustment required for argentina to reach the equilibrium rate because neighbour countries dollar exchange rates were held up by argentina s overvaluation as is indicated by their depreciation in 2002 argentina was particularly vulnerable to the sudden stop because of the extreme volatility of its portfolio inflows fiscal policy simulations suggest that even with a substantially improved primary balance from 1994 onwards loss of investor confidence would still have triggered unsustainable debt dynamics once the recession began to bite after 1998 the stagnation of output and prices in argentina created a yawning gap between the interest rate on debt and the rate of growth of nominal gdp had the currency been floated in say 1995 the real devaluation of the peso would still have pushed up the debt gdp ratio but higher output would have left greater scope for addressing this by running a sizeable primary surplus moreover the more gradual depreciation under floating might have allowed the economy to adjust to higher debt service payments without resort to default the imf has criticised itself for not pressing for tighter fiscal policy in the 1990s a more fundamental criticism would be that it was seduced by the bipolar model into complacency about adjustment to real shocks and forgetting the teachings of optimum currency area theory

maturity mismatching and market failure the present article is a continuation of the debate two sets of authors bagus and howden vs barnett and block have been engaging in regarding one type of maturity mismatching borrowing short and lending long bsll all four authors had agreed that this practice can set up the austrian business cycle the present author denies that bsll would be a legitimate commercial interaction in the free society bagus and howden continue to maintain that it would be licit our main criticism of bagus and howden is a reductio ad absurdum that this opens them up to the charge of embracing the doctrine of market failure this is something highly problematic for the two of them since all four contributors to this debate are well known supporters of laissez faire capitalism

currency boards more than a quick fix currency boards more than a quick fix once a popular colonial monetary arrangement currency boards fell into disuse as countries gained political independence but recently currency boards have made a remarkable come back this essay takes a critical look at their performance are currency boards really a panacea for achieving low inflation and high growth or do they merely provide a quick fix allowing authorities to neglect fundamental reforms and thus fail to yield lasting benefits we have three major findings first the historical track record of currency boards is sterling with few instances of speculative attacks and virtually no involuntary exits countries that did exit from currency boards did so mainly for political rather than economic reasons and such exits were usually uneventful second modern currency boards have often been instituted to gain credibility following a period of high or hyperinflation and in this regard have been remarkably successful countries with currency boards experienced lower inflation and higher if more volatile gdp growth compared to both floating regimes and simple pegs the inflation difference reflects both a lower growth rate of money supply a discipline effect and a faster growth of money demand a credibility effect the gdp growth effect is significant but may simply reflect a rebound from depressed levels third case studies reveal the successful introduction of a currency board to be far from trivial requiring lengthy legal and institutional changes as well as a broad economic and social consensus for the implied commitment moreover there are thorny issues as yet untested regarding possible exits from a currency board thus currency boards do not provide easy solutions but if introduced in the right circumstances with some built in flexibility they can be an important tool for gaining credibility and achieving macroeconomic stabilization atish r ghosh anne marie and holger c wolf

india and the impossible trinity in the 1990s india responded to the well known trilemma of macroeconomic policy by adopting an intermediate exchange rate system combined with selective capital controls this regime enabled the country to balance exchange rate stability exchange rate targeting and monetary autonomy and to weather successfully various shocks that included contagion from the east asian crisis india s experience serves to reinforce doubts about the desirability of bipolar exchange rate regimes for developing countries as an integral element of a new international financial architecture

the international monetary system in the last and next 20 years the last two decades have seen far reaching changes in the structure of the international monetary system europe moved from the european monetary system to the euro china adopted a dollar peg and then moved to a basket band and crawl in 2005 emerging markets passed through a series of crises leading some to adopt regimes of greater exchange rate flexibility and others to rethink the pace of capital account liberalization interpreting these developments is no easy task some observers conclude that recent trends are confirmation of the bipolar view that intermediate exchange rate arrangements are disappearing while members of the fear of floating school conclude precisely the opposite we show that the two views can be reconciled if one distinguishes countries by their stage of economic and financial development among the advanced countries intermediate regimes have essentially disappeared this supports the bipolar view for the group of countries for which it was first developed within this subgroup the dominant movement has been toward hard pegs reflecting monetary unification in europe while emerging markets have also seen a decline in the prevalence of intermediate arrangements these regimes still account for more than a third of the relevant subsample here the majority of the evacuees have moved to floats rather than fixes reflecting the absence of emu like arrangements in other parts of the world among developing countries the prevalence of intermediate regimes has again declined but less dramatically where these regimes accounted for two thirds of the developing country subsample in 1990 they account for a bit more than half of that subsample today as with emerging markets the majority of those abandoning the middle have moved to floats rather than hard pegs the gradual nature of these trends does not suggest that intermediate regimes will disappear outside the advanced countries anytime soon barry eichengreen and raul razo garcia

cost of business cycles with indivisibilities and liquidity constraints it is almost universally agreed that individuals face incomplete insurance markets and cannot perfectly insure against the idiosyncratic risk in this paper simple general equilibrium models with incomplete insurance markets are examined in order to assess the impact of imperfect insurance on the magnitude of the welfare costs of business cycles two versions of incomplete insurance markets are considered and certain statistical properties of the equilibrium stochastic processes in these environments are compared with those of a perfect insurance economy

the dynamics of a newly floating exchange rate the turkish case in recent years many emerging market economies have switched or are in the process of switching to a floating exchange rate regime most of these economies have a history of high inflation and a high level of foreign currency denominated debt therefore the stability of the exchange rate and the dynamics of its volatility are more crucial than before this paper analyses the dynamics of exchange rate in turkey in the aftermath of recent float in february 2001 the turkish experience is a particularly important one and provides valuable lessons for other countries as the central bank is trying to simultaneously contain the volatility of exchange rate and pursue an implicit inflation targeting policy the reported findings indicate that the central bank policies accompanied with favourable external factors were effective in taming the volatility of the exchange rate in a relatively short period of time however there is a significant real appreciation of the currency during the same period given the

the cost of business cycles and the stabilization value of unemployment insurance this paper o ers a new perspective on why labor market policies aimed at reducing the cost of business cycles may be warranted and how such policies can be designed in order to improve welfare to this end we develop a quantitative dynamic equilibrium model to illustrate how the contractual structure of the labor market may hide signi cant undiversi ed wage risk induced by aggregate uctuations the environment analyzed is such that the only imperfectly diversi ed risk workers bear is the risk of losing their job when the market for new contracts is depressed when we t the model to replicate the amount of wage variation estimated from micro data we obtain estimates of the potential value of stabilization policies that are substantially larger than those found in the literature we use this framework to examine several policy issues and in particular to show why state contingent unemployment insurance may dominate non contingent unemployment insurance schemes 2001 elsevier science b v all rights reserved jel classixcation e32 j41

measuring exchange rate misalignment in turkey we propose a new methodology to measure exchange rate misalignment for turkey which has already undergone a severe economic crisis we estimate the real exchange rate within a time varying parameter model where a return to normality assumption about the parameters are assumed contrary to common belief it is found that except the initial four months of the stabilization program the turkish lira remained structurally undervalued for most of 2000 also we observe a pattern where lira has been structurally overvalued after the crisis in 1994 until 1998 and has displayed structural undervaluation after then

on the welfare cost of economic fluctuations in developing countries macroeconomic fluctuations are much stronger in developing countries than in the united states yet while a large literature debates the welfare cost of economic fluctuations in the united states it remains an open question how large that cost is in developing countries using several models we provide such a measure we find that the welfare cost of consumption volatility per se is far from trivial and averages a substantial multiple of the corresponding u s estimate moreover in many poor countries the welfare gain from eliminating volatility may in fact exceed the welfare gain from an additional percentage point of growth forever

monetary policy vagabonding liquidity and bursting bubbles in new and emerging markets an overinvestment view credit booms have globally fuelled hikes in stock raw material and real estate markets which have culminated in the recent us subprime market crisis we explain the global asset market booms since the mid 1980s based on the overinvestment theories of hayek wicksell and schumpeter we argue that ample liquidity supply originating in the large industrialized countries has contributed to overinvestment cycles in japan east asia new markets in the industrial countries and many emerging market economies expansionary monetary policies in response to the burst of bubbles are argued to have contributed to vagabonding bubbles around the globe

the cost of business cycles under endogenous growth robert e lucas jr argued that the welfare gains from reducing aggregate consumption volatility are negligible subsequent work that revisited his calculation continued to find small welfare benefits further reinforcing the perception that business cycles do not matter this paper argues instead that fluctuations can affect welfare by affecting the growth rate of consumption i show that fluctuations can reduce growth starting from a given initial consumption which can imply substantial welfare effects as lucas himself observed empirical evidence suggests the welfare effects are likely to be substantial about two orders of magnitude greater than lucas original estimates

the mirage of exchange rate regimes for emerging market countries this paper argues that much of the debate on choosing an exchange rate regime misses the boat it begins by discussing the standard theory of choice between exchange rate regimes and then explores the weaknesses in this theory especially when it is applied to emerging market economies it then discusses a range of institutional traits that might predispose a country to favor either fixed or floating rates and then turns to the converse question of whether the choice of exchange rate regime may favor the development of certain desirable institutional traits the conclusion from the analysis is that the choice of exchange rate regime is likely to be of second order importance to the development of good fiscal financial and monetary institutions in producing macroeconomic success in emerging market countries this suggests that less attention should be focused on the general question whether a floating or a fixed exchange rate is preferable and more on these deeper institutional arrangements a focus on institutional reforms rather than on the exchange rate regime may encourage emerging market countries to be healthier and less prone to the crises that we have seen in recent years

the choice of exchange rate regime and speculative attacks we develop a framework for studying the choice of exchange rate regime in an open economy where the local currency is vulnerable to speculative attacks the optimal regime is determined by a policymaker who trades off the loss from nominal exchange rate uncertainty against the cost of maintaining a given regime this cost is affected in turn by the likelihood of a speculative attack searching for the optimal regime within the class of exchange rate bands we show that the optimal regime is either a peg a zero width band a free float an infinite width band or a non degenerate finite width band the paper shows that lower costs of moving across currencies induce policymakers to set more flexible exchange rate systems this lowers ceteris paribus the likelihood of financial crises one implication is that a tobin tax does not necessarily reduce the likelihood of currency crises the paper also investigates the effects of country size openess variability in fundamentals and reputation on the choice of exchange rate regime the role of abrupt changes in reputation in triggerering crises even with unchanged fundamentals as an alternative to sunspots is discussed and illustrated

job displacement risk and the cost of business cycles this paper analyzes the welfare costs of business cycles when workers face uninsurable job displacement risk that has a cyclical component using a simple general equilibrium model with incomplete markets this paper shows the following result for sufficiently high degree of risk aversion at least one cyclical variations in the long term earnings losses of displaced workers can generate arbitrarily large cost of business cycles even if the second moments of the distribution of individual income changes are constant over the cycle thus the previous literature which has either disregarded long term earnings losses of displaced workers or dealt with them only indirectly using second moment analysis might have severely under estimated the welfare cost of business cycles in addition to the theoretical analysis this paper also conducts a quantitative study of the cost of business cycles using empirical evidence on the long term earnings losses of u s workers the quantitative analysis suggests that cyclical variations in job displacement risk generate sizable cost of business cycles

the imf s unmet challenges the international monetary fund is a controversial institution whose interventions regularly provoke passionate reactions we will argue that there is an important role for the imf in helping to solve information commitment and coordination problems with significant implications for the stability of national economies and the international monetary and financial system in executing these functions the effectiveness of the imf like that of a football referee depends on whether the players see it as competent and impartial we will argue that the fund s perceived competence and impartiality and hence its effectiveness are limited by its failure to meet four challenges concerning the quality of its surveillance of individual countries groups of countries and the global system the relevance of conditionality in loan contracts the utility of the fund s approach to debt problems and the fund s failure to adopt a system of governance that gives appropriate voice to different stakeholders these problems of legitimacy will have to be addressed in order for the imf to play a more effective role in the 21st century

words deeds and outcomes a survey on the growth effects of exchange rate regimes abstract recent studies on the growth effects of exchange rate regimes offer a wide range of different sometimes contradictory results in this paper we systematically compare three prominent contributions in this field using a common data set a common specification and common estimation methods we argue that the contradictory findings can be explained by the fact that these studies use regime classifications which reflect fundamentally different aspects of exchange rate policy
