This paper seeks to integrate more closely the theory of optimum currency areas with the theory of international trade. The currency area is considered as a continuous variable ranging from zero to one: zero if there is no enlargement, and some positive value otherwise, corresponding exactly to...

Why is there delay in contests? In this Paper we follow and extend the line of reasoning of Carl von Clausewitz to explain delay. For a given contest technology, delay may occur if there is an asymmetry between defense and attack, if the expected change in relative strengths is moderate, and if...

We relate the phenomena of sluggish interregional labour reallocation and in-kind compensation in Russia to 'attachment' strategies of firms: Paying wages in non-monetary forms makes it hard for workers to raise the cash needed for quitting their region in order to find better jobs in more...

Contestants have to choose whether to initiate a contest or war, or whether to remain peaceful for another period. We find that agents wait and initiate the contest once their rival is sufficiently weak to be an easy target.

This paper employs worldwide data on output and bilateral trade in order to identify optimum currency areas (OCA’s) on a global basis. By retaining only two of the many criteria that have been mentioned in the literature on OCA’s, it has been possible to use computer programming to do the...

Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

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...

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 explores the link between trade and European labour markets by using evidence on relative commodity prices and intra-sectoral skill levels at the NACE three-digit level for the four large EC countries and for the period 1976–90. We find that if the relative import prices of...

A simple model of offshoring, which depicts offshoring as ‘shadow migration,’ permits straightforward derivation of necessary and sufficient conditions for the effects on wages, prices, production and trade. We show that offshoring requires modification of the four classic international...
