Revisiting the Identification of the Conduct Parameter in Homogeneous Goods Markets

Yuri Matsumura, Suguru Otani

We revisit the identification of the conduct parameter in homogeneous goods markets. Lau (1982) argues that the conduct parameter is not identified if and only if the inverse deman…

Conduct Parameter Estimation in Homogeneous Goods Markets with Equilibrium Existence and Uniqueness Conditions: The Case of Log-linear Specification

Yuri Matsumura, Suguru Otani

We propose a constrained generalized method of moments (GMM) estimator with some equilibrium uniqueness conditions for estimating the conduct parameter in a log-linear model with h…

Challenges in Statistically Rejecting the Perfect Competition Hypothesis Using Imperfect Competition Data

Yuri Matsumura, Suguru Otani

We theoretically prove why statistically rejecting the null hypothesis of perfect competition is challenging, known as a common problem in the literature. We also assess the finite…
