On the (nonlinear) relationship between exchange rate uncertainty and trade: An investigation of US trade figures in the Group of Seven

In this paper bilateral models formalizing monthly growth of US imports and exports are employed to investigate the potential of nonlinear relationships linking exchange rate uncertainty and trade growth. Parametric linear and nonlinear as well as semiparametric time series models are evaluated in terms of fitting and ex ante forecasting. The overall impact of exchange rate variations on trade growth is found to be weak. In periods of large exchange rate variations, trade growth forecasts gain from conditioning on volatility. Empirical results support the view that the relationship of interest might be nonlinear and, moreover, lacks homogeneity across countries and imports vs. export

External military threat and the response of the member states of the Gulf Co-operation Council (GCC)

The study shows that procurements of traditional arms by two countries have the possibility of moving together over time. This is demonstrated with reference to Iran and the member states of the Gulf Co-operation Council (GCC) for the period 1961- 1996. Acquiring arms by the member states of the GCC is shown to be only a response to the perception of their leaders to the external threat posed by Iran throughout the varying regimes that have ruled Teheran. In the light of the recent emergence of macroeconomic problems such as unemployment in the economies of the GCC coupled with the ineffectiveness of the financially exhausting build-up of arms as a military deterrent policy, one important implication of the study is that the priority of the GCC leaders will have to turn to a more effective deterrent policy such as acquiring nuclear technology rather than engaging in a costly and unsuccessful Arab military alliance as experienced in the 1970s.

Exchange Rate Volatility and Export Performance: A Cointegrated VAR Approach

Abstract: During the last decades Norwegian exporters have ƒ{ despite various forms of exchange rate targeting ƒ{ faced a rather volatile exchange rate which may have influenced their behaviour. Recently, the shift to inflation targeting and a freely floating exchange rate has brought about an even more volatile exchange rate. We examine the causal link between export performance and exchange rate volatility across different monetary policy regimes within the cointegrated VAR framework using the implied conditional variance from a GARCH model as a measure of volatility. Although treating the volatility measure as either a stationary or a non-stationary variable in the VAR, we are not able to find any evidence suggesting that export performance has been significantly affected by exchange rate uncertainty. We find, however, that volatility changes proxied by blip dummies related to the monetary policy change from a fixed to a managed floating exchange rate and the Asian financial crises during the 1990s enter significantly in a dynamic model for export growth ƒ{ in which the level of relative prices and world market demand together with the level of exports constitute a significant cointegration relationship. A forecasting exercise on the dynamic model rejects the hypothesis that increased exchange rate volatility in the wake of inflation targeting in the monetary policy has had a significant impact on export performance.
