Trade policy reforms in recent decades have sharply reduced the distortions that were harming agriculture in developing countries, yet global trade in farm products continues to be far more distorted than trade in nonfarm goods. Those distortions reduce some forms of poverty and inequality but...

This paper examines whether, in the presence of trade preferences, Sub-Saharan African economies, and especially its poorest households, could gain from multilateral trade reform. The World Bank’s LINKAGE model of the global economy is employed to examine the impact first of current trade...

The first generation of genetically modified (GM) crop varieties sought to increase farmer profitability through cost reductions or higher yields. The next generation of GM food research is focusing also on breeding for attributes of interest to consumers, beginning with ‘golden rice’, which...

This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but the...

This paper divides the population into two groups: the "inheritors" or "rentiers" (whose wealth is smaller than the capitalized value of their inherited wealth, i.e. who consumed more than their labor income during their lifetime); and the "savers" or "self-made men" (whose wealth is larger than...

In this article, I study the effect of worker heterogeneities on wages and unemployment within the context of a directed search model. A worker's productivity in a given firm depends both on their type and on a worker-firm specific component. Firms advertise unconditional wage offers, and hire...

This Paper analyses the evolution of quantitative measures of employee rents in Europe during the nineties, using the European Household Panel Survey. I look at two classes of measures: wage differentials between workers along industry and firm size dimensions; and estimated welfare differences...

We introduce non-homothetic preferences into a general equilibrium model of monopolistic competition and explore the impact of income inequality on the medium-run macroeconomic equilibrium. We find that (i) a sufficiently high extent of inequality divides the economy into mass consumption...

Internet development holds the promise of transmitting economic value across physical space at zero marginal cost. In such a 'weightless economy', what factors matter for the location of economic activity and thus for economic development? This paper sketches a model of spatial dynamics over a...

Models of labour market equilibrium where forward-looking decisions maximize both profits and labour income on a risk-neutral basis, offer valuable insights into the effects of employment protection legislation. Since risk-neutral behaviour in the labour market presumes perfect insurance,...
