The adoption of the International Monetary Fund (IMF) Structural Adjustment Programme (SAP) in 1986 resulted in the transition from fixed exchange rate regime to floating exchange rate regime in Nigeria. Ever since, the exchange rate of naira vis-à-vis the U.S dollar has attained varying rates all through different time horizons. On this basis, this study examines the consistency, persistency, ...

The volatility dynamics of foreign exchanges have been the focus of research since Bollerslev’s (1986) seminal work on the generalized autoregressive conditional heteroscedasticity (GARCH) modelling. Several well-established empirical regularities may be highlighted as follows: [a] evidence of volatility clustering is detected in the exchange rates returns; [b] asymmetric effects in exchange ra...

This paper analyzes the effects of pegged and floating exchange rates using a two-country dynamic general equilibrium model that is calibrated to the US and a European aggregate. The model assumes shocks to money, productivity and the interest rate parity condition. It captures the fact that the sharp increase in nominal exchange rate volatility after the end of the Bretton Woods (BW) system wa...

The relation between the volatilities of pricing kernels associated with different currencies and the volatility of the exchange rate between the currencies is derived under the assumption of integrated capital markets, and the volatilities of the pricing kernels are related to the foreign exchange risk premium. Time series of pricing kernel volatilities are estimated from panel data on bond yi...

in this paper, based on a new keynesian structure, we have analyzed monetary policy response to exchange rate volatilities in iran. for this purpose, first, exchange rate derived from equilibrium condition in exchange market and then two different models have been estimated. assumption on the first model is that central bank responses to exchange rate volatilities and the assumption on the seco...

In this paper, we investigate the long run dynamics of the intraday range of the GBP/USD, JPY/USD and CHF/USD exchange rates. We use a non-parametric filter to extract the low frequency component of the intraday range, and model the cyclical deviation of the range from the long run trend as a stationary autoregressive process. We find that the long run trend is time-varying but highly persisten...

We compare forecasts of the realized volatility of the exchange rate returns of the Euro against the U.S. Dollar and the Japanese Yen obtained both directly and through decomposition. Decomposing the realized volatility into its continuous sample path and jump components, and modeling and forecasting them separately instead of directly forecasting the realized volatility, is shown to lead to im...

This paper documents a new " stylized fact " regarding commodity prices using alternative datasets covering the period from 1880 to 1996: The volatility of real commodity prices, defined as nominal commodity prices deflated by the manufacturing unit value index, is higher under flexible-exchange rate regimes than fixed-exchange rate regimes. Furthermore, changes in exchange regime are associate...

Two issues; the liberalisation of labour markets and monetary unification, have taken centre stage in policy debates on the future of the European Union. We show that both have the effect of raising capital mobility as well as labour-market flexibility. The reduction of exchange-rate fluctuations reduces the cost of both entering a market – by setting up companies and hiring new employees – as ...
