The authors construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity....

The objective of this study is to investigate the validity of the Kaldor-Verdoorn's Law in explaining the long run determinants of the labor productivity growth for the manufacturing sector of some developed economies (Western European Countries, Australia, Canada, Japan and United States). We...

Regional unemployment rates in the European Union (EU-15) reveal a core-periphery structure. Large ?core? regions in the middle of the continent have low unemployment rates, whereas excessive mass unemployment is predominantly found in the peripheral regions at the outside borders of EU-15. This...

Economic activities are highly clustered. Why is geographic con-centrationbecoming a predominant feature of modern economies? Onthe basis of the empirical models developed by the 'new' theories ofinternational trade, our answer is that increasing returns are the driv-ingforce of economic...

This paper reconsiders the theoretical foundations of EU regional policy in economics. It begins with a discussion of the line of thought of its prevalent explanation in equilibrium economics which is focusing on market failures as its key underpinning and which is the major toolkit of...

A growing body of empirical evidence shows that there exists a long-run positive tradeoff between inflation and real macroeconomic activity. Within a New Keynesian framewok, we examine how increasing returns generate a positive long-run relation between inflation and output.

We address the notion of dynamic, endogenous diversity and its role in theories of investment and technological innovation. We develop a formal model of an innovation arising from the combination of two existing modules with the objective to optimize the net benefits of diversity. The model...

This note shows that in a developing economy, agriculture and Special Economic Zones (SEZ) can grow simultaneously without affecting one another if an appropriate subsidy policy is designed by the government. We consider increasing returns brought about by external economies of scale in the...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...
