Following the structure of many commodity markets, we consider a few large firms and a competitive fringe of many small suppliers choosing quantities in an infinite-horizon setting subject to demand shocks. We show that a collusive agreement among the large firms may not only bring an output...

It is widely accepted that one of the most important characteristics of an effective climate policy is to provide firms with credible incentives to make long-run investments in R&D that can drastically reduce emissions. Recognizing that a government may be tempted to revise its policy design...

In an effort to reduce air pollution and congestion, Latin American cities have experimented with different policies to persuade drivers to give up their cars in favor of public transport. Two notable examples are the driving restriction program introduced in Mexico-City in November of 1989...

We study the static and dynamic implications of non-linear pricing schemes (i.e., bundling) for otherwise unrelated products but for multimarket contact. Bundling is always present in competition but unlikely in a cartel agreement. Although it brings extra profits to the cartel –sometimes...

This study investigates when a cartel that uses a sales quota allocation scheme monitors more frequently than it enforces; for example, monitoring of sales is done on a weekly basis but firms are only required to comply with sales quotas on a quarterly basis. In a simple three-period quantity...

In an effort to reduce pollution and congestion, Latin American cities have experimented with different policies to persuade drivers to give up their cars in favor of public transport. Borrowing from the bundling literature, the paper presents a novel model of vertical and horizontal...

Hacia fines del 2012 debe entrar en vigencia una nueva ley de pesca en reemplazo de la actual Ley No. 19.713. Varios analistas han argumentado que la nueva ley se debe hacer cargo, entre otras cosas, de la baja competencia en el sector y de la falta de entrada de nuevos actores. En este trabajo...

En este artículo se discuten los efectos de escalar los cargos de acceso por sobre los costos marginales en los incentivos de un operador de telefonía local integrado verticalmente a implementar una práctica de precios predatorios en algunos de los servicios desregulados (e.g., larga...

A tradeable permits market is said to be efficient when all affected firms trade permits until their marginal costs equal the market price. Detailed firm-level data are generally required to perform such an efficiency test, yet such information is rarely available. If firms face a declining...

We consider a market for storable pollution permits in which a large agent and a fringe of small agents gradually consume a stock of permits until they reach a long-run emissions limit. The subgame-perfect equilibrium exhibits no market power unless the large agent’s share of the initial stock...
