This paper provides a brief overview of the evolution of exchange rate policy in the Islamic Republic of Iran from 1993 to 2002 and reviews the basic criteria for the choice of the exchange rate regime in the medium term. The analysis highlights the merits of an intermediate regime which would allow the authorities to smooth out excessive short-term exchange rate fluctuations while letting nominal exchange rate movements facilitate real exchange rate adjustments called for by major oil price shocks.

Exchange rate-based inflation stabilization (ERBS) policies are associated with a boom-recession cycle in economic activity and sustained real exchange rate appreciation. A class of models in the literature has explained these empirical regularities with the lack of credibility of the stabilization plans. The lack-of-credibility models typically assume perfectly forward-looking pricing behavior without inflation stickiness and attribute the slow decline in inflation to the consumption boom that occurs due to the perceived temporariness of the ERBS policy. This paper tests the empirical validity of forward-looking pricing behavior in Mexico and Turkey, two countries which have experienced ERBS. It finds that the forward- and backward-looking components of inflation weigh approximately equally in pricing behavior, and therefore, that inflation is partially sticky. The paper then develops the theoretical implications of partial inflation stickiness in a lack of credibility model of ERBS and concludes that the presence of stickiness significantly reduces the persistence of the consumption boom predicted by the model, but helps to explain the recession in the late phase of the stabilization.

Abstract

The recent boom in unconventional energy production is transforming the energy landscape in North America, with important implications for global energy markets and the broader competitiveness outlook. This book, within a unifying policy perspective, examines the impact the upsurge in energy production has had on the manufacturing sectors of the United States, Canada, and Mexico, and of the region as a whole, which produces nearly a quarter of the world’s energy.

This study examines money demand and inflation dynamics in the Islamic Republic of Iran using quarterly data for the period 1990/91-2001/02 and tests whether the disinflation during 2000/01-2001/02 represents a structural break in the data. A long-run money market equilibrium condition is identified and the short-run behavior of the inflation, measured in terms of non-administered component of the consumer price index (CPI) is modeled conditional on the disequilibria in the money market. Estimation results indicate that the stabilization of the exchange rate on account of strong oil revenues during 2000/01-2001/02 buoyed the demand for domestic money and contributed to the decline in inflation. Tests of model stability do not point to a structural shift in the inflation equation during the period of analysis.

Using data on syndicated loan issuances by emerging market firms, we find that an increase in the external debt of emerging market governments significantly raises the borrowing costs of the domestic corporate sector. This finding suggests that a higher level of public external debt "crowds out" foreign credit to the private sector by increasing the risk of a sovereign debt crisis and thereby making exposure to corporate sector debt less desirable. The effect is stronger in countries with weak creditor rights. The results highlight the potential costs of fiscal expansions for the domestic corporate sector even when debt is issued in foreign markets.
