This paper reviews the recent literature on game-theoretic models of market structure and their empirical implementation.

Convergence concerns poor economies catching up with rich ones. At is- sue is what happens to the cross sectional distribution of economies, not whether a single economy tends towards its own steady state. It is the latter, however, that has preoccupied the traditional approach to con- vergence...

Inequality measures are powerful tools of applied welfare analysis. However, to use the tools effectively one has to take into account the characteristics of the data with which one usually has to work. These raise a number of common statistical problems which are addressed here for both...

This paper analyses how the degree of regional integration affects regional differences in production structures and income levels. With high transport costs, industry is spead across regions to meet final consumer demad. As transport costs fall, increasing returns interacting with labour...

Kelly (1992) has recently shown that evidence on convergence cannot be taken as evidence against endogenous growth in general. This study uses a well-known class of stochastic growth models to show other dicul- ties with traditional empirical studies of convergence. Key parameters typically...

We develop a model in which the interaction between transport costs, increasing returns, and labour migration across sectors and regions creates a tendency for urban agglomeration. Demand from rural areas favours urban dispersion. European urbanisation took place mainly in the XIX Century, with...

The conventional view that product heterogeneity limits the scope for collusion among oligolpolists has been challenged in recent theoretical work. This paper provides an argument in support of the conventional view by emphasising the role of uncertainty. I introduce the idea that, with...

This paper outlines a new approach for analysing the role of trade in promoting industrial development. It offers an explanation as to why firms are reluctant to move to economics with lower labour costs, and shows how trade liberalisation can change the incentives for firms to locate in...
