the speculative attack on the peso and the real exchange rate argentina 1979 1981 abstract this article applies a speculative attack model to argentina during its pre announced exchange rate system from january 1 1979 to june 30 1981 the model attempts to verify a rule whereby if domestic credit growth exceeds the rate of currency depreciation two things occur first the domestic price of non traded goods rises relative to the price of traded goods second foreign reserves decline until a point when a sudden speculative attack depletes remaining reserves causes a precipitous fall in the relative price of non tradables and forces the country onto a floating exchange rate regime in some important respects the model captures the argentinian experience yet in other respects if fails to do so

a quality adjusted price index for personal computers this study estimates quality adjusted price indexes for personal computers three separate hedonic models are estimated using data from 1 841 personal computers over the period 1984 1991 in addition to the traditional linear model a nonlinear model is developed and estimated the nonlinear model is parsimonious in parameters allows time varying attribute prices and can be estimated using a pooled data set the results indicate that nominal quality adjusted prices of mail order firms declined at an average annual rate of 24 62 quality adjusted prices of major manufacturers declined at a slower rate

predicting exchange rate crises mexico revisited abstract this paper predicts ex ante probabilities of currency crises and sizes of expected devaluations month by month for mexico between 1980 and 1986 the forces contributing to speculative attacks on the mexican peso include domestic fiscal and monetary shocks external credit shocks and relative price shocks reducing domestic credit growth increasing the uncertainty surrounding this growth and reducing the size and perhaps increasing the frequency of currency realignments might have greatly reduced the amount of currency speculation against the peso between 1980 and 1986 anticipated external credit supply shocks played a relatively minor role during mexico s balance of payments crises

collusion and overlending i introduction for a long time have korean companies been engaged in unbridled expansionism financed through loans inefficient octopus style management and over and duplicate investment thus expediting the structural failure of the economy this failure to concentrate on profits consolidation and efficiency provided the fuse to the bankruptcy bombs that triggered the foreign exchange and economic crises the collusion between the conglomerates financial sector and politicians made this financial monopoly possible chosun ilbo december 26 1997 collusion and overlending in the korean financial sector may be best illustrated by the above editorial highlight of chosun ilbo the most read newspaper in korea its 1997 financial crisis is primarily triggered by continual bankruptcies of chaebols conglomerates which with assistance from politicians had borrowed heavily from financial institutions in financing their investment projects 1 unlike some other asian countries experiencing problems in their financial sector due to shifts in investment projects toward real estates such as japan hong kong and thailand chaebols in korea concentrated mostly on manufacturing activities 2 in this study we establish a tractable model of overlending with three key players namely chaebols financial institutions and politicians as highlighted in chosun ilbo the model is designed to achieve two primary goals that are crucial for matching some key observations during the korean turmoil first we illustrate how overlending can be an equilibrium outcome with collusion between chaebols and politicians when the economic environment is favorable this occurs despite that such a collusion distorts normal borrowing lending operation by causing a discernible shift in loan composition from more to less productive investment projects second we show that as the economic environment gradually deteriorates there can be a shift from a collusion to a no collusion equilibrium the combination of deterioration in fundamentals and expectations of an equilibrium shift can trigger economy wide financial crisis more specifically we construct a simple principal supervisor agent model of corruption and overlending the principal is the formal authority of loan decision making of a financial institution or in short the financial institution the supervisor is a politician who serves as the informational intermediary in the borrowing lending arrangement via his her connections and networking 3 the agent is a chaebol of an unknown type which seeks for external financing of a set of risky projects a politician s favorable signal about the borrowing chaebol s overall performance would grant the approval of the loan to finance an array of risky projects whose returns depend on idiosyncratic shocks that cannot be washed out in aggregation within the chaebol as an outside alternative to making the loan the financial institution can invest in the world capital market where a fixed rate of return is guaranteed this portfolio decision depends on a comparison of the expected average returns on the given set of risky projects with the safe returns on investments in the world capital market while both the chaebol s type and the state of nature are unobservable to the financial institution we for simplicity assume that politician s connections and networking can fully uncover the true type of the chaebol this valuable information possessed by the politician is one that the financial institution has an incentive to purchase but a low type chaebol has an incentive to conceal whether the politician ends up revealing truthfully this information depends on how much to obtain from the lender in terms of general support versus how much to gain from the borrower in terms of bribes or side payments when a low type chaebol has the politician on its side information is distorted and a collusion equilibrium arises

the political economy of basle ii the costs for poor countries the financial crises of the 1990s triggered many changes to the design of the international financial system we use the formulation of the new basle capital accord for banks b ii to illustrate that while much affected developing countries have had very little influence on this so called new international financial architecture we argue that b ii has been formulated largely to serve the interests of powerful market players with developing countries being left out at the same time we demonstrate that b ii is likely to raise the costs and reduce the supply of external financing for developing countries in particular furthermore and importantly b ii may well increase the pro cyclicality of external financing an unfortunate outcome given that developing countries already face much volatility in terms of capital flows overall while b ii may indeed compensate for a range of weaknesses of basle i the exclusionary policy process and costs which b ii imposes on developing countries require a re think of the way in which crucial elements of financial governance such as the basle capital accords are developed and implemented

speculative currency attacks with endogenously induced commercial bank crises abstract to date all models of exchange rate crises ignore the existence of a commercial banking sector however if deposit money internal drain is used to purchase foreign exchange external drain then an external drain may give rise to a banking crisis the paper illustrates how an internal drain alters the dynamics of a speculative attack when it results in a cash payments restriction by interrupting the external drain such a restriction postpones devaluation and reduces the size of the initial devaluation the us internal and external drains of 1893 are discussed to provide motivation and support for the model

a new approach to modeling early warning systems for currency crises can a machine learning fuzzy expert system predict the currency crises effectively abstract this paper presents a hybrid causal model for predicting the occurrence of currency crises by using the neuro fuzzy modeling approach the model integrates the learning ability of the neural network with the inference mechanism of fuzzy logic the empirical results show that the proposed neuro fuzzy model leads to a better prediction of crisis significantly the model can also construct a reliable causal relationship among the variables through the obtained knowledge base compared to neural network and the traditionally used techniques such as logit the proposed model can thus lead to a somewhat more prescriptive modeling approach based on determinate causal mechanisms towards finding ways to prevent currency crises

likelihood versus timing of speculative attacks a case study of mexico abstract this paper estimates a survival model to identify the role of macroeconomic fundamentals on the likelihood and the timing of a currency crisis for mexico during 1982 1994 foreign reserve losses expansionary output expansionary monetary and fiscal policies an increase in inflation differentials and an appreciation of the real exchange rate appear to have contributed to the speculative pressures on the other hand the decline in foreign reserves and the increase in the share of short term foreign currency indexed debt seem to be the main factors which determined the timing of speculative attacks

the persistence of the peso problem when policy is noisy abstract the peso problem the market s belief that a discrete event may occur has frequently been blamed for the persistence of on average mistaken forecasts of macroeconomic variables this paper demonstrates how beliefs that a policy process may have switched can induce apparent ex post biased forecasts of exchange rates even after the switch has occurred furthermore during this peso problem period exchange rates may appear to contain a speculative bubble component since they will systematically deviate from the levels implied by observing fundamentals ex post and the conditional variance of exchange rates will exceed the variance implied by observing fundamentals

quality adjusted price and quantity indices for pesticides quality adjusted price indices are calculated for pesticides used on major crops in u s agriculture for 1967 92 using hedonic methods pesticide potency hazardous characteristics and persistence in the environment are used as quality characteristics separate hedonic functions are estimated for pesticides by end use crop and major pesticide class price indices are aggregated using chained tornqvist indices adjusted quantity indices are computed using pesticide expenditures the adjusted price index rose steadily reaching in 1992 around 2 5 times the level of 1968 pesticide use at constant quality peaked in 1981 at a level substantially higher than the peak reached by the unadjusted index

balance of payments crises and devaluation the collapse of a fixed exchange rate is typically marked by a sudden balance of payments crisis in which speculators fleeing from the domestic currency acquire a large portion of the central bank s foreign exchange holdings faced with such an attack the central bank often withdraws temporarily from the foreign exchange market allowing the exchange rate to float freely before devaluing and returning to a fixed rate regime this paper links the timing of the initial speculative attack to the magnitude of the expected devaluation and to the length of the transitional period off loating an implication of the analysis is that there exist devaluations so sharp and transition periods so short that acrisis must occur the moment the market first learns that the current exchange parity will eventually be altered for sufficiently long transition periods the floating exchange rate overshoots its new peg before appreciating back toward it for shorter periods the rate depreciates monotonically to its new fixed level accordingly the central bank s return tothe foreign exchange market can occasion a capital outflow or a capital inflow this abstract was borrowed from another version of this item

speculative currency attacks and balance of payments crises abstract this paper reviews the recent theoretical literature on collapsing exchange rate regimes using a combination of technique intuition and realworld observation we discuss the literature s main insights point out some unresolved questions and offer suggestions for future research the survey should be of interest to both specialists and non specialists in the field of international macroeconomics

speculation and the decision to abandon a fixed exchange rate regime this paper investigates the extent to which it is possible for speculative attacks to be predictable given information on economic fundamentals a standard model of predictable attacks is extended to incorporate an optimizing monetary authority it is shown that while incorporating a forward looking monetary authority improves our understanding of many observed phenomena it also implies that the branch of the literature that places emphasis on predictable movements in fundamentals cannot generate predictable speculative attacks in addition the model provides useful insights into the viability of temporary nominal anchor policies and a theoretical foundation for an important empirical methodology

on the choice of funtional form for hedonic price functions this study examines how errors in measuring marginal attribute pric es vary with the form of the hedonic price function in simulations consumers with known utility functions bid for houses with given attributes various forms of the hedonic function are estimated using equilibrium housing prices errors in estimating marginal attribute prices are calculated by comparing each consumer s equilibrium marginal bid vector with the gradient of the hedonic function when all attributes are observed linear and quadratic box cox forms produce lowest mean percentage errors however when some attributes are unobserved or are replaced by proxies linear and linear box cox functions perform best copyright 1988 by mit press

collapsing exchange rate regimes shocks and biases abstract patterns in domestic credit creation stemming from inconsistent fiscal policies have received widespread attention for their role in aggrevating speculative attacks on central bank foreign exchange reserves and contributing to the collapse of exchange rate regimes this paper acknowledges the importance of monetary and fiscal discipline but also emphasizes the importance of other random shocks to the domestic money market most notably shocks from external credit supplies and relative prices policies of the domestic fiscal authorities are only partial catalysts for speculative attacks on a currency expansion of domestic credit stemming from the monetization of fiscal imbalances may be dominated by involuntary domestic credit expansions which are necessitated by surprise shortages in supplies of external capital further the unexpected availability of external capital translates into a lower net critical reserve floor making the depletion of central bank reserves by a speculative attack more difficult to accomplish relative price shocks also randomize the demand for nominal money balances and therefore may also have a strong direct influence on the probability of an exchange regime collapse empirical studies of exchange rate crises that neglect these considerations will produce biased estimates of both expected collapse probabilities and anticipated post collapse exchange rates

speculative attacks and macroeconomic fundamentals evidence from some european currencies abstract this paper evaluates the role of macroeconomic fundamentals in generating episodes of speculative pressures on six currencies of the european exchange rate mechanism erm the observed regime changes are first estimated by a set of speculative pressure indicators the contribution of economic fundamentals are then examined by using the implications of the basic speculative attack literature in general episodes of speculative pressures appear to be associated with a deterioration in economic fundamentals only for some of the sample currencies confirming the view that consistent macro policies are necessary but not sufficient to ensure the maintenance of an exchange rate peg

a critical evaluation of exchange rate policy in turkey abstract this paper reviews and critically evaluates the exchange rate policy followed in turkey in the post 1980 period during which a far reaching program of liberalization has been launched we conclude that the new exchange rate policy has been essential for turkey s regaining its creditworthiness furthermore it has positively contributed to growth of output and exports and to expansion of tradables production relative to nontradables persistence of inflation and weakness of private investment in tradables overshadow the successes recorded in other areas and cast doubt over the sustainability of turkey s outward orientation we argue that the root cause of these problems has been inconsistencies between overall economic policies rather than the exchange rate policy itself we compare the period of real appreciations since late 1998 with the earlier period of real depreciations and draw policy implications

effective costs and chemical use in united states agricultural production using the environment as a free input a cost function based production model is used to represent patterns of input use and output production in u s agriculture and the implied costs of induced reductions in risk from agricultural chemicals bad outputs we estimate and evaluate shadow values for these harmful outputs and the implied input and output specific substitution patterns with a focus on the impacts on pesticide demand and its quality and quantity components using state level data we find these measures to be statistically significant vary substantively by region and imply increased demand for effective pesticides associated with improvements in quality from embodied technology copyright 2002 oxford university press

learning large deviations and recurrent currency crises this article studies a version of obstfeld s journal of international economics 43 1997 61 77 escape clause model the model is calibrated to produce three rational expectations equilibria two of these equilibria are e stable and one is unstable dynamics are introduced by assuming that agents must learn about the government s decision rule it is assumed they do this using a stochastic approximation algorithm it turns out that as a certain parameter describing the sensitivity of beliefs to new information gets small the algorithm converges to a small noise diffusion process the dynamics of exchange rate changes are then characterized using large deviation techniques from freidlin and wentzell random perturbations of dynamical systems second edition berlin springer verlag 1998 these methods describe the sense in which the limiting distribution of exchange rate changes is approximated by a two state markov switching process where the two states correspond to the two e stable equilibria the model is calibrated to the exchange rate histories of argentina brazil and mexico currency crises in these countries resemble the predicted escape routes of the model a key feature of these escape routes is that expectations of a devaluation erupt suddenly without large contemporaneous shocks this is consistent with evidence showing that crises are often poorly anticipated by financial markets

balance of payments crises in an optimal portfolio model abstract balance of payments crises are often associated with large current account movements preceding and following the crises in this paper we treat the issue of balance of payments crises in a general equilibrium model to allow for such current account movements at the same time we model the portfolio decisions of the individuals in an explicit risk and return framework the resulting behavior for money demand foreign exchange reserves and current account is derived most importantly the risk and return framework allows for a discussion of the influence of uncertain government domestic credit policies on the current account behavior preceding the attack and on the probability of an attack

reserve and exchange rate cycles abstract many latin american countries appear locked into cycles of reserve loss devaluation and temporary reserve gains this paper shows how a dual exchange rate system with leakages may generate cycles in reserves and the premium between official and parallel exchange rates we study the dynamics of these cycles and their asymptotic behavior both analytically and numerically

gold monetization and gold discipline gold and its price have emerged as frequent topics of both academic and government debate 2 public attention focused on the gold market since gold s price began fluctuating violently in 1980 and 1981 has turned to gold as a possible means of removing some discretion inherent in the current fiat money system since lack of adherence to monetary rules can lead to problems of dynamic policy inconsistency academic economists have begun seriously to reconsider monetary standards based either on gold or on some other commodity as politically feasible methods of establishing rules 3

explaining the duration of exchange rate pegs abstract this paper is an empirical investigation of the duration of exchange rate pegs in 16 latin american countries and jamaica we identify factors that influence peg duration using logit analysis the real exchange rate and the level of international liquidity are significant determinants of the monthly likelihood of devaluation structural variables such as the openness of an economy and its geographical trade concentration and political variables such as changes in the executive also significantly affect the likelihood of a devaluation there is some evidence that the likelihood of a devaluation first rises and subsequently declines during the first year of a peg

the use of the exchange rate for stabilization a real interest arbitrage model applied to argentina we model interest rate and portfolio determination under the risk of real currency devaluation taking into account risk aversion on the part of investors a simple extension of the friedman savage analysis of consumer behavior under uncertainty to a two period two country setting allows us to explicitly solve for the interest rate premium paid in the risky asset the model is applied to the 1979 1980 argentinean experiment with the pre announced exchange rate empirical results suggest that a safety factor central bank reserves as a fraction of m2 is closely related to the net ex ante and ex post arbitrage differentials in favor of argentina relative to the united states jel d8

the end of an era in international financial regulation a postcrisis research agenda the global financial crisis that erupted in the summer of 2007 has made the reform of international prudential financial regulation one of the top priorities of global public policy past scholarship has usefully explained the creation and strengthening of international financial standards with reference to three policy arenas inter state domestic and transnational despite the accomplishments of this specialist literature the recent crisis has revealed a number of limitations in the ways scholars have understood inter state power relations the influence of domestic politics and the significance of transnational actors within international financial regulatory politics taken together developments in each of these three arenas suggest that researchers may also need to be prepared to shift from explaining the strengthening of official international standards to analyzing their weakening in the post crisis world the latter task will require scholars to devote more analytical attention to a wider set of international regulatory outcomes including informal regulatory convergence regulatory fragmentation and especially cooperative regulatory decentralization

speculative attack and the external constraint in a maximizing model of the balance of payments balance of payments models of speculative attack differ from non renewable resource models in that foreign exchange reserves may be borrowed from abroad this paper shows that in an idealized world where all private income is subject to lump sum taxation central bank reserves can become infinitely negative without violating the government s intertemporal budget constraint none the less a growth rate of domestic credit exceeding the world interest rate if maintained indefinitely leads to violation of the constraint in the paper s model given an assumed limit to official external borrowing the paper next analyses inevitable transitions between fixed and floating exchange rate regimes when individual preferences are explicitly specified in a discrete time deterministic model the collapse of a fixed rate may be characterized by two successive speculative attacks

financial policy and speculative runs with a crawling peg argentina 1979 1981 abstract in this paper we present a model of a balance of payments crisis and examine the argentine experiment with a crawling peg between december 1978 and february 1981 the approach taken allows us to examine the evolution of a crisis when a collapse is not perfectly foreseen and yields plausible estimates of one month ahead probabilities of a collapse of the crawling peg the results suggest that the viability of an exchange rate regime depends on the consistency of exchange rate policy with domestic credit policy if the two are not consistent confidence in exchange rate policy is undermined

rational and self fulfilling balance of payments crises speculative attacks on a pegged exchange rate must sometimes occur ifasset price paths are to be free of abnormal profit opportunities suchattacks are fully rational as they reflect the market s response to aregime breakdown that is inevitable the authors shows that under someexpectations about policy balance of payments crises can also be purely self fulfilling events in such cases even a permanently viableregime may collapse and the economy will possess multiple equilibriacorresponding to different subjective assessments of the probability ofa crisis the behavior of the domestic interest rate will naturally reflect the possibility of a speculative attack copyright 1986 by american economic association

the international monetary system forty years after bretton woods review essay in may 1984 a distinguished group of central bankers and economists gathered for a conference at bretton woods to consider the evolution of the world monetary system that was born at that location forty years earlier this volume contains nine essays with accompanying discussion on issues of performance and reform of current international monetary arrangements these papers deal with problems facing the industrialized and the lessdeveloped countries and assess the institutions that have been set up to accommodate these problems the major accomplishments of the original bretton woods conference were of course the establishment of the system of payments based on fixed exchange rates and the organization of the world bank and the international monetary fund as the order developed in the late 40 s and early 50 s each central bank saw it as its duty to intervene in foreign exchange markets to ensure an essentially fixed parity of their currency with respect to the dollar the role of the u s was to guarantee the dollar price of gold at 35 an ounce the system has been called a dollar standard because the dollar played the role of a reserve currency one of the paradoxes of the system as robert triffin pointed out in the early 60 s is that in order to produce a continuing and rapid enough expansion of world reserves the u s had to run balance of payments deficits yet continued deficits by the u s threatened the convertibility of the dollar into gold as it happened the system of fixed parities broke down in the early 70 s not because of a lack of reserves but because a glut of dollars made the bretton woods dollar exchange rates untenable the system eventually evolved into one in which most of the industrialized countries currencies more or less are determined by the market while the currencies of most second and third world countries are pegged to a major currency the floating period has been

exchange market mayhem the antecedents and aftermath of speculative attacks exchange market mayhem the antecedents and aftermath of speculative attacks this paper evaluates the causes and consequences of episodes of turbulence in foreign exchange markets using data from 1959 through 1993 for twenty oecd countries we consider the antecedents and aftermath of devaluations and revaluations flotations fixings and speculative attacks which may not be successful we find that realignments of fixed exchange rates are alike devaluations are preceded by political instability budget and current account deficits and fast growth of money and prices revaluations are mirror images of devaluations speculative attacks resemble devaluations but money growth and inflation are more endemic and there is no last minute attempt to tighten monetary policy in contrast few consistent correlations link regime transitions like flotations or fixings to macroeconomic or political variables transitions between exchange rate regimes are largely idiosyncratic and are neither consistently provoked ex ante by systematic imbalances nor typically justified ex post by subsequent changes in policy we conclude that there are no clear early warning signals of many speculative attacks and no easy solutions for policy makers barry eichengreen andrew k rose and charles wyplosz

collapsing exchange rate regimes some linear examples abstract we construct a pair of linear examples to study the collapse time of a fixed exchange rate regime the first example is a perfect foresight continuous time model which allows calculation of the exact collapse time and the tracking of reserves the second example is a discrete time stochastic model which yields an endogenous probability distribution over the collapse time and produces a forward discount of the exchange rate

foreign exchange futures prices under fixed exchange rates abstract this paper develops three models for the determination of foreign exchange futures prices under fixed exchange rates and expectations of devaluation these models show that certain characteristics of futures prices behavior that have been used as proof of inefficiency may be present even if the market is efficient they also have several implications that are consistent with the observed behavior of mexican pesos futures prices

thirty years of currency crises in argentina external shocks or domestic fragility participation has been quite volatile in the early 1800s in the midst of the lending boom fueled by the end of the napoleonic wars argentina and many other countries in latin america were able to issue bonds in london to finance their wars of independence and the civil wars that followed this lending boom ended in the summer of 1825 when the bank of england raised the discount rate to stop the drain in its reserves the tightening of liquidity was followed by stock market crashes banking problems and recessions in england and on the continent within months the crisis also spread to latin america argentina defaulted in 1827 in the midst of what is known as the first latin american debt crisis only resuming payments in 1857 similar international capital flow booms to emerging markets occurred in 1867 72 1880 90 1893 1913 and 1920 29 fueled by an easing monetary stance in the financial centers of those times and by the financial needs of railway expansion urbanization and development of the banking sector of countries in the periphery while argentina was heavily involved in all these capital flow bonanzas its participation was quite volatile with financial crises often following booms 1
