Since introduction of unit roots, researchers have tried to solve the purchasing power parity (PPP) puzzle or its failure by testing for stationarity of the real exchange rates. Failure to support the PPP is mostly said to be due to low power of these tests. Panel unit root testing is more...

Previous research that has tested the stability of the reserve demand function uses panel data, without incorporating any adjustment process into the testing procedure when providing evidence of instability in reserve demand. In this article, we use time-series data, as well as a bounds testing...

Few studies in the literature have argued that inflationary effects of devaluation redistribute income from workers to producers. By using cross-sectional data from 24 countries, this paper provides an empirical support for the theoretical arguements that indeed, devaluations have unequalizing...

In this note we employ two procedures to determine whether the adjustment of international reserves is in real or nominal terms. Using panel data from 17 DCs and 16 LDCs, we show that adjustment of actual reserves to their desired level is indeed in nominal terms.

Due to intervention in the foreign exchange market, any pressure on the external account of a country could be absorbed either by a change in reserves or by a change in the exchange rate. In this paper we employ Girton and Roper's EMPM model to investigate the experience of G7 countries. The...

Unlike previous research that investigated the relation between exports and output, in this paper we assess the long-run relation between the degree of openness and economic growth. For the many countries considered here, we find a positive long-run relation between openness and economic growth.

Devaluation is said to redistribute income from the poor, who have a high Marginal Propensity to Consume (MPC) to the rich, who have a low MPC. Assuming the high MPC group to be unskilled labour and the low MPC group to be skilled labour, we investigate the impact of currency depreciation on...

Cointegration analysis is often used in empirical studies of Purchasing Power Parity (PPP) to test whether there is a long-run relationship among countries' bilateral exchange rates and price levels. But the presence of a cointegrated relationship is not enough to support PPP, as other...

A group of studies have shown that in less developed countries, Purchasing Power Parity (PPP) theory is supported more often when black market exchange rates rather than official rates are used in the testing procedure. They have all relied upon linear Augmented Dickey-Fuller (ADF) test applied...
