Entry, exit, and imperfect competition in the long run

AMIR, Rabah; LAMBSON, Val - Center for Operations Research and Econometrics (CORE), … - 2003

An infinite-horizon, stochastic model of entry and exit with sunk costs and imperfect competition is constructed … to exhibit excessive entry and insufficient exit relative to a social optimum. …. Simple examples provide insights into: (1) the relationship between sunk costs and industry concentration, (2) entry when …

A real options model for electricity capacity expansion

GAHUNGU, Joachim; SMEERS, Yves - Center for Operations Research and Econometrics (CORE), … - 2011

This paper proposes a real option capacity expansion model for power generation with several technologies that differ in operation and investment costs. The economy is assumed perfectly competitive and the instantaneous payoff accruing from the generation system is the instantaneous welfare...

Monopolistic competition and income dispersion

OSHARIN, Alexander; THISSE, Jacques-François; USHCHEV, … - Center for Operations Research and Econometrics (CORE), … - 2013

We develop a model of monopolistic competition that accounts for consumers' heterogeneity in both incomes and preferences. This model makes it possible to study the implications of income redistribution on the toughness of competition. We show how the market outcome depends on the joint...

Endogenous heterogeneity in strategic models: symmetry-breaking via strategic substitutes and nonconcavities

AMIR, Rabah; GARCIA, Filomena; KNAUFF, Malgorzata - Center for Operations Research and Econometrics (CORE), … - 2006

This paper is an attempt to develop a uniﬁed approach to endogenous heterogeneity by constructing general class of two-player symmetric games that always possess only asymmetric pure-strategy Nash equilibria. These classes of games are characterized in some abstract sense by two general...

Concentration, spatial clustering and the size of plants : disentangling the sources of co-location externalities

LAFOURCADE, Miren; MION, Giordano - Center for Operations Research and Econometrics (CORE), … - 2003

Following the model-based approach of Ellison and Glaeser (1997), we develop a framework to test for the link between concentration, spatial clustering and the size of plants. Concentration is an a-spatial concept of variability that can be measured with the standard locational Gini or the more...

Endogenous timing with free entry

TESORIERE, Antonio - Center for Operations Research and Econometrics (CORE), … - 2006

A free entry model with linear costs is considered where firms first choose their entry time and then compete in the … outputconfigurations encompassing one limit-output dominant firm and the Cournot equilibrium with free entry as extreme cases. Sequential … entry is never observed. Both Stackelberg and Cournot-like outcomes are sustainable as equilibria however.When the number of …

Efficiency gains and mergers

DE FEO, Giuseppe - Center for Operations Research and Econometrics (CORE), … - 2008

In the theoretical literature, strong arguments have been provided in support of the efficiency defense in antitrust merger policy. One of the most often cited results is due to Williamson (1968) that shows how relatively small reduction in cost could offset the deadweight loss of a large price...

The dynamics of agglomeration : evidence from Ireland and Portugal

BARRIOS, Salvador; BERTINELLI, Luisito; STROBL, Eric; … - Center for Operations Research and Econometrics (CORE), … - 2004

This paper analyses and compares the dynamics of agglomeration in Portuguese and Irish manufacturing industries between 1985 and 1998 implementing Dumais, Ellison and Glaeser (2002) methodology. Using comparable and exhaustive micro-level data sets, we find that s industries tend to be subject...
