Acemoglu, Daron - 2010

We study the efficiency of oligopoly equilibria in a model where firms compete over capacities and prices. The … demands across the firms. We first establish the existence of pure strategy subgame perfect equilibria (oligopoly equilibria … oligopoly equilibria of this game can be arbitrarily low. However, if the best oligopoly equilibrium is selected (among multiple …

Dynamic Price Competition, Learning-by-Doing and Strategic Buyers

Sweeting, Andrew; Jia, Calvin Dun; Hui, Shen; Yao, Xinlu - 2022

We generalize recent models of dynamic price competition where sellers benefit from learning-by-doing by allowing for long-lived strategic buyers, with a single parameter capturing the extent to which each buyer internalizes future buyer surplus. Many of the equilibria that exist when buyers are...

A Dynamic Oligopoly with Collusion and Price Wars

Fershtman, Chaim; Pakes, Ariel - 2021

Most of the theoretical work on collusion and price wars assumes identical firms and an unchanging environment, assumptions which are at odds with what we know about most industries. Further that literature focuses on the impact of collusion on prices. Whether an industry can support collusion...

An Aggregative Games Approach to Merger Analysis in Multiproduct-Firm Oligopoly

Nocke, Volker - 2018

Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct-firm price competition with nested CES or nested logit demands. We show that the Herfindahl index provides an adequate measure of the welfare distortions introduced by market power, and that the induced...

Nonlinearities and the Macroeconomic Effects of Oil Prices

Hamilton, James D. - 2010

This paper reviews some of the literature on the macroeconomic effects of oil price shocks with a particular focus on possible nonlinearities in the relation and recent new results obtained by Kilian and Vigfusson (2009)

Solution Methods for Models with Rare Disasters

Fernández-Villaverde, Jesús - 2016

This paper compares different solution methods for computing the equilibrium of dynamic stochastic general equilibrium (DSGE) models with rare disasters along the line of those proposed by Rietz (1988), Barro (2006}, Gabaix (2012), and Gourio (2012). DSGE models with rare disasters require...

Heterogeneous Wealth Dynamics : On the Roles of Risk and Ability

Santos, Paulo - 2016

This paper studies the causal mechanisms behind persistent poverty. Using original data on Boran pastoralists of southern Ethiopia, we find that heterogeneous and nonlinear wealth dynamics arise purely in adverse states of nature. In favorable states, expected herd grow is quasi-linear and...
