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...

Why do countries default? This seemingly simple question has yet to be adequately answered in the literature. Indeed, prevailing modelling strategies compel the to choose between two unappealing model features: depending on the cost of default selected by the modeler, either the debt ratios are...

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 distinguish two types of debt crises: those that are the outcome of exogenous shocks (to productivity growth for instance) and those that are endogenously created, either by self-fulfilling panic in financial markets or by the reckless behavior of "Panglossian" borrowers. After Krugman, we...

We propose two distinct approaches to the measurement of industry upstreamness (or average distance from final use) and show that they yield an equivalent measure. Furthermore, we provide two additional interpretations of this measure, one of them related to the concept of forward linkages in...

International trade theory is a general-equilibrium discipline, yet most of the standard portfolio of research focuses on the production side of general equilibrium. In addition, we do not have a good understanding of the relationship between characteristics of goods in production and...

Does foreign entry improve host country productivity and welfare? Existing studies have focused on the role of technology spillovers and backward linkages with domestic suppliers. In this paper, we study how these externalities are affected by technological incompatibilities between foreign and...

We develop a simple model to study the interactions between a supplier’s financial constraints and contract incompleteness in a vertical relationship. Production complexity increases the extent of contract incompleteness and the hold-up problem, which generates a cost when the supplier needs...

Empirical studies provide evidence of positive spillovers from multinational firms to upstream suppliers coupled with negative spillovers to firms in the same industry. This paper shows that these empirical regularities can be rationalized in a model with incompatibilities between foreign and...

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...
