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...

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...

This paper aims to disentangle the correlation between LDC debt and growth in the 1980s. We show that large debt was not an unconditional predictor of slow growth in the eighties and that investment was not abnormally low, when compared with a `financial autarky' rate, calculated in the text. We...

The paper computes lifetime welfare functions for French and American workers. For the vast majority of workers, we find that the lifetime discrepancy between the welfare of an employed and that of an unemplyed worker appear to quite similar in the two countries, corresponding to nine monthly...

We analyse the buy-back of its debt by an LDC. Contrary to the analyses that were previously done on this subject, we assume that the debtor can hide its transactions behind the veil of a fictitious operator: the banks, we assume, cannot discriminate intra-bank transactions from buy-backs by the...

This paper gives a valuation formula for LDC debt that is used to assess: i) the price at which a buy-back of the debt is advantageous to the country (we shall see that it is likely to be half the observed market price); ii) the value to the creditors of having the flows of payment guaranteed...

This paper sets a framework for analysing how memoryless voters may come to elect and re-elect a committed policy-maker. Policy-makers, we assume, are trusted to implement the policy that they announce ex ante (and do implement it, if elected and re-elected). Voters, however, are never bound by...
