The literature has shown that the implied welfare gains from international financial integration are very small. We revisit the existing findings and document that welfare gains can be substantial if capital goods are not perfect substitutes. We use a model of optimal savings that includes a...

We quantify the causal effect of foreign investment on total factor productivity (tfp) using a new global firm-level database. Our identification strategy relies on exploiting the difference in the amount of foreign investment by financial and industrial investors and simultaneously controlling...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value added output, we calculate for each state the efficient frontier for investments in the real economy, the efficient Sharpe...

This Paper examines the changing relationships between the G7 countries through VAR models for the quarterly growth rates, estimated both over sub-periods and using a rolling data window. Six trivariate models are estimated, all of which include the US and a European (E15) aggregate. In relative...

The Central and Eastern European countries' prospects of becoming EU members depend heavily on, among other things, their per capita GDP levels. It is shown that the neoclassical growth model does not yet adequately describe the growth process in these countries. This makes a direct growth...

For Africa, a regional customs union is unlikely to realise net welfare gains (in the sense of trade creation dominating trade diversion) which cannot be attained through unilateral trade liberalization. Unilateral reform has often failed in Africa, however. A regional customs union tied to...

This paper considers a new approach to the optimal management and analysis of exchange rate target zones by regarding the operation of a target zone as a dynamic signalling game between the monetary authorities and the financial markets. A Sequential Open Loop (Feedback) policy of sterilized...
