This paper analyzes the determinants of remittances to Tonga. The results indicate that macroeconomic conditions in remitting countries and exchange rate fluctuations influence remittances. In particular, remittances growth falls when the Tongan currency appreciates, but increases with higher real GDP growth and lower unemployment in remitting countries. The analysis also finds that the influence of these determinants varies with the recipients of remittances, with remittances to non-profit organizations being more sensitive to an appreciation of the Tongan currency and the interest rate differential between Tonga and remitting countries than remittances to households. However, the analysis does not find evidence of "?Dutch Disease" in Tonga, as the real exchange rate does not appear to be affected by remittances.
Real Exchange Rates, Devaluation, and Adjustment provides a unified theoretical and empirical investigation of exchange rate policy and performance in scores of developing countries. It develops a theory of equilibrium and disequilibrium real exchange rates, takes up the question of why devaluations are the most controversial policy measures in poorer nations, and discusses what determines their success or failure. In a lucid fashion, Edwards organizes vast amounts of data on exchange rates - both real and nominal - and discusses their effect on net trade balances, net asset positions, output growth, real wages, and rates of price inflation, analyzed both in time series and through cross country comparisons. Edwards's investigation singles out 39 major devaluation episodes for before and after comparative analyses while simultaneously isolating the separate effects of other important explanatory variables, such as bank credit expansion and changes in the terms of trade. The first part of the book focuses on theoretical models of devaluation and real exchange rate behavior in less developed countries. Special attention is paid to intertemporal channels in the transmission of disturbances. The second part uses a large cross country data set to analyze the way the real exchange rate has behaved in these nations. The data are also used to test the implications of several theories of real exchange rate determination. The third part analyzes actual devaluation experiences between 1962 and 1982. These chapters examine the events leading to a balance of payments crisis and to a devaluation, exploring the relation between macroeconomic disequilibrium, and the imposition of trade and exchange controls. They also investigate the effect of nominal devaluation on key variables such as the balance of payments, the current account, the real exchange rate, real output real wages, and income distribution.
Serven examines empirically the link between real exchange rate uncertainty and private investment in developing countries using a large cross country-time series data set. He builds a GARCH-based measure of real exchange rate volatility and finds that it has a strong negative impact on investment, after controlling for other standard investment determinants and taking into account their potential endogeneity. The impact of uncertainty is not uniform, however. There is some evidence of threshold effects, so that uncertainty only matters when it exceeds some critical level. In addition, the negative impact of real exchange rate uncertainty on investment is significantly larger in economies that are highly open and in those with less developed financial systems.
Attempts to achieve real depreciation through continuous devaluation or by accelerating the rate of crawl - when not supported by changes in other policies and in the underlying conditions - usually end up increasing inflation, yet remain ineffective in changing the real exchange rate.
Devaluation is an integral part of adjustment in many developing countries, particularly relied upon by countries facing large external imbalances. A devaluation can only reduce trade imbalances if it translates to a real devaluation and if trade flows respond to relative prices in a significant and predictable manner. However, a recent strand in the empirical trade literature has questioned the existence of a stable relationship between trade flows and its traditional determinants. This paper re-examines the relationship between relative prices and imports and exports in a sample of 12 developing countries.
This article analyzes the theory of equilibrium real exchange rates and defines misalignment as a deviation of the real exchange rate (RER) from its equilibrium level. The role of macroeconomic policies is then analyzed under three alternative nominal exchange rate regimes: predetermined nominal exchange rates; floating nominal rates; and dual or black market nominal exchange rates. This discussion points out how inconsistent macroeconomic policies often lead to real exchange rate misalignment. Corrective measures, including nominal devaluation and several alternative approaches, are then evaluated.
