Exchange Rate Management Under Uncertainty


Book Description

These twelve essays take up economic management under flexible exchange rates in the presence of uncertainty. Nearly all of the contributions adopt a rational expectations framework, focusing on the stochastic aspects of the assumption and exploring the variability of, for example, output and prices in relation to the variability of various external disturbances.Jagdeep Bhandari is Associate Professor of International Economics at West Virginia University.




Exchange Rate Management in Interdependent Economies


Book Description

With the breakdown of the Bretton Woods System and the begin of floating between the major currencies, central banks have been formally freed from their obligations to defend the fixed parities of bilateral exchange rates. Nev ertheless, since then there have been countless occasions on which monetary authorities have officially intervened in the foreign exchange market. More over, numerous studies indicate that exchange rates have been much more variable than originally anticipated - in real and in nominal, as well as in short run and longer run measures (see for example Hesse and Braasch [1989] and Marston [1988]). Through the experience of high real sector costs, the topic of optimal exchange rate management soon reentered policy discussions. The term exchange rate management encompasses both the choice of ex change rate regime as well as active intervention policies within the given 1 system. Much of the recent policy discussion has focussed on the first issue, in particular proposals of how to reform the present international monetary order. And new systems such as the European Monetary System (EMS) have emerged for subgroups of countries. However, the question of finding the optimal system has not yet been resolved.




Stabilization with Exchange Rate Management Under Uncertainty


Book Description

Stabilization programs in open economies typically consist of two stages. In the first stage the rate of currency devaluation is reduced, but the fiscal adjustment does not eliminate the fiscal deficit which causes growth of debt and loss of reserves, making a future policy change necessary. Only later, at a second stage, is this followed by either an abandonment of exchange rate management or by a sufficiently large cut in the fiscal deficit. We study how different second-stage policy changes affect economic dynamics during the first stage. These changes include tax increases, budget cuts on traded and nontraded goods, and increases in the growth rate of money. Under certainty about the timing and nature of a switch, current account developments provide information about which policy instrument is expected to be used for stabilization. Uncertainty about the timing of a stabilization is shown to be important in explaining phenomena such as continuous reserve losses and the possibility that a policy change is accompanied by a surprise discrete devaluation rather than a run on reserves




Exchange Rate Uncertainty in Money-Based Stabilization Programs


Book Description

Complementing the explanation provided by Calvo and Vegh (1994) for money-based stabilization programs, exchange rate uncertainty introduced to a particular version of the portfolio approach with imperfect competition in the banking system leads to a bias toward appreciation that is directly related to the divergence of expectations and that dampens the interaction between portfolio movements and the real exchange rate. Based on Frankel-Froot, uncertainty exists when the fundamental equilibrium real exchange rate is temporarily unknown in a foreign exchange market with two types of agents: ‘parity-guessers,’ who expect a jump to a reference parity level, and ‘money-followers,’ who expect nominal depreciation equal to the monetary rule.




Inflation Targeting and Exchange Rate Management In Less Developed Countries


Book Description

We analyze coordination of monetary and exchange rate policy in a two-sector model of a small open economy featuring imperfect substitution between domestic and foreign financial assets. Our central finding is that management of the exchange rate greatly enhances the efficacy of inflation targeting. In a flexible exchange rate system, inflation targeting incurs a high risk of indeterminacy where macroeconomic fluctuations can be driven by self-fulfilling expectations. Moreover, small inflation shocks may escalate into much larger increases in inflation ex post. Both problems disappear when the central bank leans heavily against the wind in a managed float.




Foreign Exchange Intervention Rules for Central Banks: A Risk-based Framework


Book Description

This paper presents a rule for foreign exchange interventions (FXI), designed to preserve financial stability in floating exchange rate arrangements. The FXI rule addresses a market failure: the absence of hedging solution for tail exchange rate risk in the market (i.e. high volatility). Market impairment or overshoot of exchange rate between two equilibria could generate high volatility and threaten financial stability due to unhedged exposure to exchange rate risk in the economy. The rule uses the concept of Value at Risk (VaR) to define FXI triggers. While it provides to the market a hedge against tail risk, the rule allows the exchange rate to smoothly adjust to new equilibria. In addition, the rule is budget neutral over the medium term, encourages a prudent risk management in the market, and is more resilient to speculative attacks than other rules, such as fixed-volatility rules. The empirical methodology is backtested on Banco Mexico’s FXIs data between 2008 and 2016.







Exchange Rate Economics


Book Description

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""
