The capital-output ratio is more than 40% lower in the poor countries than in the richest ones. Comparing TFP in manufacturing and in the economy at large, we show that the Balassa-Samuelson effect explains the bulk of this scarcity: TFP in manufacturing is indeed about 40% lower than TFP in the...

This Discussion Paper analyses 23 industrial sector in a sample of 51 developed and developing countries. It distinguishes the contribution of five factors: private capital, infrastructure, education, trade integration, and net efficiency. Several relatively small handicaps, combined...

The dynamic inconsistency of a government's preferred policy, when it occurs, usually implies that the maximum level of welfare that can be delivered at some initial time can only be attained by constraining the economy to `low' levels in the future. In this paper, we set up a linear quadratic...

We analyze a two-country zone facing a joint inflationary shock and responding with coordinated and uncoordinated monetary and fiscal policies. We show that the standard presumption that the absence of coordination results in an excessive exchange rate appreciation of the zone with respect to...

I argue in this paper that the `speed of convergence' estimated in recent works on `convergence' does not capture `actual' convergence towards a steady state, but rather conditional dynamics towards a moving target. Although this conditional convergence can be taken to imply that there are...

Against all odds, the euro turned out to be a weak currency. We argue that this outcome can readily be explained by the policy mix that was chosen at the onset of the period: tight fiscal policies following the convergence mechanism that was imposed by the Maastricht treaty and loose monetary...

Commodity prices are usually very slow to recover from adverse shocks. This is one of the reasons why it has proven so difficult either to smooth their effect or to stabilize them, and why it is sometimes argued that they should behave as if shocks were permanent. There is no reason however why...

We distinguish two attitudes towards debt. The attitude of prudent borrowers, which attempt to stabilize their debts to low levels, even in the event of a bad shock, and what we call, after Krugman, "Panglossian" borrowers, which only focus on the best of their growth prospects, and rationally...

We argue in this paper that cancelling the debt of the poorest countries was a good thing, but that it should not imply that the debt instrument should be foregone. We claim that debt and debt cancellations are indeed two complementary instruments which, if properly managed, perform better than...

The paper attempts to explain why single factor explanations of the poverty of nations are usually found to be unsatisfactory. Poor countries outside Africa, for instance, have an income per head which stands at about one third of the rich countries’ income per head. Yet each of the three...
