This paper addresses whether parallel market exchange rates in Africa behave in the long run in a manner consistent with the purchasing power parity (PPP) hypothesis. A recent econometric method, the panel co-integration test, enables us to examine the long-run PPP hypothesis by pooling the...

Using the ARFIMA-FIGARCH model, this paper studies the efficiency of the Japanese equity market by examining the statistical properties of the return and volatility of the Nikkei 225. It shows that both follow a long range dependence, which stands against the efficient market hypothesis (EMH)....

This paper empirically evaluates the validity of the term structure of interest rates in a low-interest-rate environment. Applying a time-series method to high-frequency Japanese data, the term-structure model is found to be useful for economic analysis only when interest rates are high. When...

This paper empirically analyzes Japanese long-run exchange rates from several perspectives. Several exchange rate models are considered, including the purchasing power parity, the real interest differential model, and the hybrid models à la Hooper and Morton (1982). A notable feature of the...

The paper estimates Angola’s equilibrium parallel market real exchange rate during the 1992–98 period. Using standard integration/co-integration techniques, the results fail to support the purchasing power parity hypothesis and indicate that two exogenous variables—the price of oil and the...

This paper empirically examines the long-run relationship between real exchange rates and real interest rate differentials over the recent floating exchange rate period, using a panel cointegration method, with data for a set of industrialized countries. The paper finds evidence of statistically...
