In this paper we use a non cooperative equilibrium selection approach as a notion of stability in link formation games. Specifically, we follow the global games approach first introduced by Carlsson and van Damme (1993), to study the robustness of the set of Nash equilibria for a class of link...

We present a model of investment under uncertainty about fundamentals, using a global games approach. Goldstein & Razin (2003) show that there is an information based trade-off between foreign direct investment (FDI) and portfolio investment (PI) which rationalizes some well known stylised facts...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country's relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare...

This paper formulates a dynamic model of global carbon consumption in the absence of an effective international agreement. Each period, countries extract carbon from the global ecosystem. A country's output depends both on its carbon usage and on the ecosystem ("stored carbon"). The desired mix...

The traditional exception to the welfare reducing character of protectionism is based on the optimum tariff argument. If in addition the market power can be traced back to control of a necessary, cero substitution natural resource type input, then the corresponding trade tax and the shadow price...

This paper presents a simple methodology to estimate the elasticity of substitution between labor and capital for firms operating in perfectly competitive markets with CRS production functions. It is applied in a cross-country sample to 28 3-digit ISIC manufacturing industries. The econometric...

This paper uses a new data set to estimate the causes and consequences of foreign currency debt in rms' balance sheet. The vidence from this sample of Chilean firms indicates that dollar-denominated debt is more used by larger firms and those more exposed to foreign competition. We find evidence...

Este trabajo evalúa los impactos de la política fiscal sobre la evolución de la actividad económica (PIB) en Chile. Los resultados del análisis dinámico con la metodología de VAR estructural indican efectos no keynesianos de la política fiscal. Un aumento (reducción) en el gasto fiscal...

Efficient regulation of the commons requires information about the regulated firms that is rarely available to regulators (e.g., cost of pollution abatement). Different mechanisms have been proposed for inducing firms to reveal their private information but for reasons I discuss in the paper, I...

Noncontributory subsidies for the old poor (first-pillar pensions) affect the welfare of hundreds of millions around the world. Their benevolent rationale is to redistribute progressively, subject to efficiency considerations. This paper focuses on a critical efficiency issue: first pillars may...
