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

economies of traffic density in the deregulated airline industry this article estimates a structural model of competition among hub and spoke airlines in order to measure the strength of economies of traffic density on individual route segments we find that economies of density were strong during the sample period fourth quarter 1985 stronger than previous estimates by douglas caves laurits christensen and michael tretheway derived from traditional cost function methods we also find that the airlines competitive behavior was far from collusive in the markets under study markets requiring a connection at a hub airport our structural model also provides plausible estimates of demand elasticities we use our estimates to provide a cost based rationale for the major changes in the structure of the industry following deregulation for example the increase in airport and industry wide concentration and the increase in competition at the city pair market level and to simulate the effects of a merger of airlines that share a hub

assessing firm behavior in carve out markets evidence on the impact of carve out policy abstract airlines wanting to cooperatively set prices for their international air travel service must apply to the relevant authorities for antitrust immunity ati while cooperation may yield benefits it can also have anti competitive effects in markets where partners competed prior to receiving ati a carve out policy forbids ati partners from cooperating in markets policymakers believe will be most harmed by anti competitive effects we examine carve out policy applications to three ati partner pairings and find evidence more consistent with cooperative pricing in carve out markets in spite of the policy calling into question the effectiveness of the policy in achieving intended market outcomes

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

competition in airline networks the case of constant elasticity demands abstract this paper is concerned with the effect of competition in airline hub and spoke networks using constant elasticity demand functions we demonstrate that competition in a single market may generate positive or negative network externalities depending on price elasticities of demand

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

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

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

the economics of international codesharing an analysis of airline alliances abstract international airline alliances allow airlines to coordinate their operations in providing international service this paper analyzes the effect of such alliances on traffic levels fares and welfare in the model the benefits of alliances arise because cooperative pricing of trips by the partners puts downward pressure on fares in the interline city pair markets these are markets where travel on both carriers is necessary the loss of competition in the interhub market which connects the hub cites of the partners generates a countervailing effect tending to raise the fare in that market while the presence of economies of traffic density complicates these impacts by generating cost links across markets simulation analysis shows that the above tendencies typically prevail welfare analysis shows that both consumer and total surplus typically rise following formation of an alliance despite the harm to interhub passengers suggesting that the positive effects of alliances may outweigh any negative impacts

the economics of hubs the case of monopoly in this paper we study the optimization problem of an unregulated air carrier which is given the exclusive right to satisfy demand for air travel between any pair of cities it chooses a network of connections and a set of prices to maximize profits thus both network design and prices are endogenous we characterize the solution to this optimization problem when demands and costs are symmetric our main result is that if there are economies of density in the number of individuals travelling between two directly connected cities the optimal network is either a hub of size n 1 or one in which every pair of cities is connected directly

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

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

the imf and precautionary lending an empirical evaluation of the selectivity and effectiveness of the flexible credit line abstract this paper provides an empirical evaluation of the flexible credit line fcl the imf s prime precautionary lending instrument since 2009 to which so far only mexico colombia and poland have subscribed we consider both questions of selectivity and effectiveness first which variables explain the three countries participation in fcl arrangements and second to which extent has the fcl delivered on its promise of boosting market confidence in its respective users based on a probit analysis we show that fcl selectivity can be explained by both demand and supply side factors the probability of participation in the fcl was greater in countries that experienced larger prior exchange market pressures that had lower bond spreads and inflation that accounted for higher shares in us exports and that exhibited a higher propensity of making political concessions to the us using a synthetic control approach we find evidence for some but generally limited beneficial effects on sovereign bond spreads and gross capital inflows into the three fcl countries overall our results suggest that any economic stigma that may prevent eligible countries from entering into an fcl arrangement is unwarranted conversely the apparent link of fcl participation with us interests is not conducive to overcoming political stigma

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

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

impacts of code share alliances on airline cost structure a truncated third order translog estimation abstract the airline industry has undergone significant changes following deregulation more than a decade ago a prominent development in recent years has been the proliferation of airline alliances an important question arises are alliances cost savings or competition reducing this paper addresses the first part of the question however the answer has bearing on the second part as well since results in industrial economics suggest that unless a merger or alliance can substantially reduce costs consumers are unlikely to enjoy lower prices e g farrell j and c shapiro 1990 horizontal mergers an equilibrium analysis american economic review 80 1 107 26 this paper estimates a truncated third order translog cost function using quarterly firm level data of 10 airlines for the period 1994qi to 2001qi using the estimated function we assess whether alliances have any impacts on costs and if so the extent to which the cost structure of airlines are affected it is found that the truncated third order translog is an appropriate specification and alliances do appear to lower costs however while the impacts are statistically significant in economic terms the magnitude appears to be immaterial

irregular growth cycles this paper uses the familiar neoclassical theory of capital accumulation to show how complex behavior can emerge from quite simple economic structures indeed when sufficient nonlinearities and a production lag are present the interaction alone of the propensity to save and the productivity of capital can lead to growth cycles that exhibit a wandering sawtooth pattern not unlike those observed in reality these fluctuations need not converge to a cycle of any regular periodicity so they are not quasi periodic because such chaotic trajectories are unstable errors of estimation in parameters or initial conditions however tiny will accumulate rapidly into substantial errors of forecast moreover periods of erratic cycling can be interspersed with periods of more or less stable growth evidently the future behavior of a model solution cannot be anticipated from its patterns in the past a situation that seems to mimic experience apparent structural change and unpredictability is explained in the present theory by a deterministic single equation model random shocks play no role so the reader can visualize just what it is we are are talking about a noteworthy simulation is presented in figure 1 for gnp in a growth model that is described below in section iii a period of relatively rapid growth is followed by a period of cycles then remarkably for a considerable time about twenty periods apparently steady state growth occurs wandering cycles however emerge another brief period close to the steady state appears again toward the end of the series i establish conditions of savings and productivity that lead to results of this kind this analysis makes use of the mathematical theory of chaos which in the form exploited here originated in the work of edward lorenz a formal definition of chaos and sufficient conditions for chaotic trajectories were provided in a seminal paper by t y li and james yorke a survey of these related contributions is found in yorke and evelyn yorke this theory was introduced into economics by jess benhabib and myself 1981 where we showed that sequences of rational choices can be erratic when preferences depend on experience in a certain way by michael stutzer who provides a detailed analysis of trygve haavelmo s growth model by benhabib and myself 1980 in an application of the overlapping generations model and in my forthcoming study of the classical growth model

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

effective demand in a sequence of markets a consumer s effective demand is defined in a model where prices are fixed at nonclearing levels where markets are visited sequentially and where there is stochastic rationing this concept of effective demand is compared to that proposed by lower grossman and benassy and that proposed by dreze the influence of transaction costs on effective demand and the choice of an optimal order of visits to the markets are also dealt with

entry deterrence and strategic alliances researchers have written extensively on the impact that strategic alliances between airlines have on airfare but little is known of the market entry deterrent impact of strategic alliances using a structural econometric model this paper examines the market entry deterrent impact of codesharing a form of strategic alliance between incumbent carriers in domestic air travel markets we find evidence of market entry deterrence but deterrence impact depends on the specific type of codesharing between market incumbents as well as the identity of the potential entrant we quantify the extent to which market incumbents codesharing influences potential entrants market entry cost and probability of market entry

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

airline code share alliances and their competitive effects abstract code share alliances have become a prominent feature in the competitive landscape of the airline industry however policy makers are extremely hesitant to approve proposed code share alliances when the potential partners route networks have significant overlap the main concern is that an alliance may facilitate price collusion on partners overlapping routes this article shows how policy makers can use a structural econometric framework to quantify the competitive effects of proposed code share alliances where potential alliance partners compete on overlapping routes in the prealliance industry as an example i apply the econometric model to the delta continental northwest alliance this proposed alliance was initially greeted with skepticism by the u s department of transportation owing to the potential partners unprecedented level of route network overlap for the markets considered in my analyses it appears as though the ultimate approval of the alliance by policy makers was justified

domestic airline alliances and consumer welfare this article investigates the consumer welfare consequences of the recent code share agreement between continental airlines and northwest airlines we develop a discrete choice model based on individual flight characteristics this structural model recognizes that consumers i may have heterogeneous preferences for flight attributes and ii may face different prices for the same flight the empirical methodology also deals with the measurement error problem stemming from the absence of consumer level data on prices the estimation results suggest that whereas the code share agreement did not impact consumers significantly on average it increased the average surplus of connecting passengers but decreased the average surplus of nonstop passengers interestingly the magnitude of our welfare results may be attributed in large part to changes in product characteristics other than prices

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

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

the economics of airport congestion pricing abstract conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports several characteristics of aviation markets however may make naive congestion prices equal to the value of marginal travel delays a non optimal response this paper develops a model of airport pricing that captures a number of these features the model in particular reflects that 1 airlines typically have market power and are engaged in oligopolistic competition at different sub markets 2 part of external travel delays that aircraft impose are internal to an operator and hence should not be accounted for in congestion tolls and 3 different airports in an international network will typically not be regulated by the same authority we present an analytical treatment for a simple two node network and some numerical results to illustrate our findings some main conclusions are that second best optimal tolls are typically lower than what would be suggested by congestion costs alone and may even be negative and that cooperation between regulators need not be stable but that non cooperation may lead to welfare losses also when compared to a no tolling situation

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

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

the price effects of international airline alliances abstract this paper provides evidence on the effect of international airline alliances on fares the main finding is that alliance partners charge interline fares that are approximately 25 percent below those charged by nonallied carriers according to our theoretical model the main source of this fare reduction is the internalization of a negative externality that arises from the uncoordinated choice of interline sub fares in the absence of an alliance the paper also looks for evidence of an anti competitive alliance effect in the gateway to gateway markets while the point estimates show that an alliance between two previously competitive carriers would raise fares by about 5 percent this effect is not statistically significant

hybrid cooperation agreements in networks the case of the airline industry abstract this paper develops a unified framework to analyze a continuum of hybrid cooperation agreements along two dimensions their degree of revenue sharing scope of alliances and their degree of cost sharing scope of joint ventures the analysis focuses on the air transportation industry distinguishing between interline and interhub markets as economies of traffic density become stronger we find that the socially optimal cooperation agreement moves from full alliance to joint venture in interline markets whereas it moves from joint ventureto merger in interhub markets these results are driven by the tradeoff between a procompetitive effect of alliances in interline markets and an anticompetitive effect in interhub markets along with the efficiency gains associated with joint ventures in interhub markets we also develop an empirical application for intercontinental routes for the period 2010 2016 that identifies a positive impact of deeper degrees of airline cooperation revenue and cost sharing on traffic both in interline and interhub markets therefore the potential anticompetitive effect of deeper alliances in interhub markets is not observed in our sample

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

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

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

international airfares in the age of alliances the effects of codesharing and antitrust immunity this paper provides empirical evidence showing the effect of airline cooperation on the interline fares paid by international passengers the analysis focuses on two measures of cooperation codesharing and antitrust immunity and the results show that their partial effects are both negative the presence of codesharing on an international interline itinerary reduces the fare by 8 17 with the exact number depending on the sample used and the estimation method moreover the presence of antitrust immunity reduces the fare by 13 21 codesharing and immunity are substitutes however in the sense that their combined effect is smaller than the sum of their partial effects taking account of this difference which is captured by an interaction variable in the regressions the combined effect ranges between 17 and 30 these results provide strong evidence that airline cooperation in the fare setting process generates substantial benefits for interline passengers

complex dynamics in a simple macro disequilibrium model abstract this study analyzes disequilibrium dynamics in a simple macro economic model constructed with micro foundation in which the behavior of individual economic agents concerning consumption labor supply employment output supply and the formation of expectation can be described by very simple and conventional monotonic functions it is demonstrated that despite that simplicity complex nonlinear dynamics may appear through the interaction of those individual behavior in different markets

on macroeconomic equilibrium with stochastic rationing the purpose of this paper is to apply the ideas of stochastic rationing mechanisms to a simple disequilibrium macroeconomic model it has been shown that effective demands with stochastic rationing as opposed to those derived from deterministic constraints the clower benassy or dreze effective demand are consistent with the maximization of expected utility and are also capable of producing unsatisfied demand and supply in a quantity constrained equilibrium the well known regime classification of quantity constrained equilibria i e keynesian unemployment classical unemployment repressed inflation and underconsumption is shown to be relevant in a macroeconomic framework with stochastic rationing comparative statics of quantity constrained equilibria are worked out for different regimes

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

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

monopoly competition and information acquisition abstract an incumbent monopolist is uncertain about its linear demand but can acquire public information at a cost we determine how an entry threat affects the firm s information acquisition if returns to scale are constant and the state contingent demands become more dispersed as output increases then entry reduces information acquisition if however either the incumbent or entrant has increasing returns or if the state contingent demands are nonlinear or fail increasing dispersion then entry can increase information finally entry can hurt consumers although entry always increases output it can decrease information consumers sometimes prefer a better informed monopoly to a duopoly

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

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

rivalry between strategic alliances abstract rivalry between strategic alliances is investigated in a model where each alliance member maximizes its own profit and some share of its partner s profit a complementary alliance confers a strategic advantage by allowing the partners to credibly commit to greater output owing to both within alliance complementarities and cross alliance substitutabilities although rivalry between different alliances can sometimes lead to a prisoners dilemma for firms it tends to improve economic welfare on the other hand an alliance that arises due purely to the threat of entry may reduce welfare

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

ergodic fluctuations in deterministic economic models abstract nonperiodic business fluctuations are shown to exist with positive measure generically and to behave like stationary stochastic processes in the standard dynamic macro model the implication is that so called chaotic fluctuations are probable for random initial conditions in a large class of recursive economies

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

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

stationary keynesian equilibria equilibria with keynesian unemployment are studied in the framework of a simple macroeconomic model assuming that they result from a non t tonnement at fixed prices and wages

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

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

international reserves before and after the global crisis is there no end to hoarding we evaluate the impact of the global financial crisis gfc and recent structural changes in the patterns of hoarding international reserves ir we confirm that the determinants of ir hoarding evolve with developments in the global economy during the pre gfc period of 1999 2006 gross saving is associated with higher ir in developing and emerging markets the negative impact of outward direct investment on ir accumulation is consistent with the recent trend of diverting international assets from the international reserve account into tangible foreign assets the joneses effect lends support to the regional rivalry in hoarding ir as a motivation and commodity price volatility induces precautionary buffer hoarding during the 2007 2009 gfc period previously significant variables become insignificant or display the opposite effect probably reflecting the frantic market conditions driven by financial instability nevertheless the propensity to import and gross saving continue to display strong and even larger positive effects on ir holding the results from the 2010 2012 post gfc period are dominated by factors that had been mostly overlooked in earlier decades while the negative effect of swap agreements and the positive effect of gross saving on ir holdings are in line with our expectations we find a change in the link between outward direct investment and ir in the pre and post crisis period the macro prudential policy tends to complement ir accumulation developed countries display different demand behaviors for irs higher gross saving is associated with lower ir holding possibly reflecting high income countries tendency to deploy their savings in the global capital markets the presence of sovereign wealth funds motivates developed countries to hold a lower level of ir our predictive exercise affirms that an emerging market economy with insufficient ir holdings in 2012 tends to experience exchange rate depreciation against the u s dollar when many emerging markets were adjusted to the news of tapering quantitative easing in 2013
