This chapter describes how the spatial distribution of economic activity changes as economies develop and grow. We start with the relation between development and rural-urban migration. Moving beyond the coarse rural-urban distinction, we then focus on the continuum of locations in an economy...

This paper examines the relationship between openness and within-country regional inequality across 28 countries over the period 1975-2005. In particular, it tests a) whether increases in trade lead to rising inequalities, b) whether these inequalities recede in time, and c) whether increases in...

We study long-run trends in aggregate market hours of work and shifts across economic sectors within the context of balanced aggregate growth. We show that a model of many goods and uneven TFP growth in market and home production can rationalize the observed falling or U-shaped aggregate hours...

The comovement between exports and productivity observed in many countries suggests a direct link between these two variables. This paper tries to establish whether such a causal link exists for four developed market economies, using co-integration and Granger-causality techniques. These...

In this we specify and jointly estimate supply, demand and price equations for four aggregate commodity groups: food, beverages, agricultural raw materials and metals. This simple structural model allows us, for each group of commodities, to incorporate stock data for the first time, and to...

The purpose of this paper is to provide a simple model which illuminates the interdependence between primary commodity prices and the rest of the economy. We study the role of commodity prices in a disinflation program, the role of commodity prices in determining whether or not a fiscal...
