Continental drift: European integration and the location of U.K. foreign direct investment

Article Abstract:

The European Union (EU) internal market and economic integration in general have been accompanied by an increase in foreign direct investment (FDI). The proportion of UK FDI going to other EU countries has increased, especially since 1986 and the Single European Act. There is also evidence that some investment has been switched from the US to Europe after 1990. More than a third of the additional investment can be accounted for by the financial services industry.

Long-memory risk premia in exchange rates

Article Abstract:

An analysis of the time series properties of forecast errors, spot rates and forward premia for a number of currencies in the inter-war and post-war periods of floating exchange rates can provide valuable information about the effectiveness of fractionally integrated models. It has been found that forward premia frequently appear to be well described by fractional processes. This indicates that risk premia follow fractional processes given rational expectations.
