We present a new data set for years of schooling across countries for the 1960–2000 period. The series are constructed from the OECD database on educational attainment and from surveys published by UNESCO. Two features that improve the quality of our data with respect to other series,...

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 Paper presents a new set of data on human capital. It is constructed so as to stay as close as possible to the censuses compiled by national, OECD or UNESCO sources. We then use these data to test a model that embeds the Mincerian approach to human capital into the Mankiw, Romer and Weil...

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...

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...

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...
