This paper presents a model in which growth and geographic agglomeration of economic activities are mutually self reinforcing processes. Industrial agglomeration in one location spurs growth because it reduces the cost of innovation in that location through a pecuniary externality due to...

This paper describes the possible impact of multi-speed integration on the location of economic activities in Europe. We present a model where two countries integrate their economies and leave a third temporarily outside because of its lower income. We analyse the effect of different integration...

This paper takes a modest step towards formalizing the theoretical interconnections among four post-Industrial-Revolution phenomena – the industrialization and growth take-off of rich ‘northern’ nations, massive global income divergence, and rapid trade expansion. Specifically, we present...

This paper constructs a model of endogenous growth and endogenous industry location where the two interact. We show that with global spillovers in R&D, a high growth rate and a high level of transaction costs are associated with relocation of the newly created firms to the South (the location...

Recent empirical tests of dynamic optimal seigniorage models focus on their `smoothing' and long-run implications. The models also imply that the optimal policies are forward looking; that is seigniorage revenues depend on expected future government expenditures. We report causality tests of...

When learning-by-doing is at the origin of growth, we show that growth rates should be negatively related to the amplitude of the business cycle if the growth rate in human capital is increasing and concave in the cyclical component of production. Empirical evidence strongly supports this...

This paper analyses the effect of different types of regional subsidies to poor regions on industrial location, employment, income inequality - between and inside regions - and welfare. We show that the impact on location of such subsidies is stronger when trade costs are low. When firms are...

This paper analyses how country size affects exchange rate policy and volatility. A hump-shaped relation between exchange rate variability and the size of countries is generated in the theoretical model: exchange rate variability increases with country size for small countries, but then...

The paper investigates the impact of financial integration on asset return, risk diversification and breadth of financial markets. We analyse a three-country macroeconomic model in which i) the number of financial assets is endogenous; ii) assets are imperfect substitutes; iii) cross-border...

This paper analyzes the reaction of exporters to exchange rate changes. We present a model where, in the presence of distribution costs in the export market, high and low productivity firms react differently to a depreciation . Whereas high productivity firms optimally raise their markup rather...
