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...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

We provide a novel set of stylized facts on firms engaging in international trade in services, using unique data on firm-level exports and imports from the world's second largest services exporter, the United Kingdom (UK). We show that only a fraction of UK firms engage in international trade in...

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in...

This paper presents a new model of the domino effect which is used to generate an empirical index of how "contagious" FTAs are with respect to third nations due to the trade diversion. We test our contagion hypothesis together with alternative specifications of interdependence and other...

The increased integration of the economies of Central and Eastern Europe with the European Union (EU) as the Europe Agreements are progressively implemented, is projected to have a significant impact on trade flows with Spain, as exports and imports grow very rapidly, albeit starting from a very...

Exchange risk hedging in a static (i.e. one-period) setting is extremely straightforward. The variance-minimizing hedge of a particular future cash flow involves a forward contract equal but opposite in sign to the exposure of the cash flow. The exposure is the regression coefficient of the cash...

Development accounting exercises based on an aggregate production function find technology is biased in favour of a country's abundant production factors. We provide an explanation to this finding based on the Heckscher-Ohlin model. Countries trade and specialize in the industries that use...

This paper develops a model to analyse the implications of firing costs on incentives for R&D and international specialization. The key idea is that, to avoid paying firing costs, the country with a rigid labour market will tend to produce relatively secure goods, at late stages in their product...

The demise of the CMEA trading system in 1991 and the shift to convertible currency settlements and world market prices was expected to bring about a severe contraction of intra-group trade, coupled with large imbalances in trade between Eastern Europe and the former Soviet Union. The observed...
