Seminar Abstract 【Endogenous Cost Differentials between Public and Private Enterprises: A Mixed Duopoly Approach】 ------------------------------ Speaker: 松島 法明 Affiliation: 信州大学 経済学部 Date and Time: 2002.10.29 (Tue), 4:30 - 6:00 p.m. Place: 3F1136 Chair: 江口 匡太 ------------------------------ Abstract: We investigate a mixed duopoly, where a state-owned welfare-maximizing public firm competes against a profit-maximizing private firm. We use a Hotelling-type spatial model which presents product differentiation. We endogenize production costs by introducing cost-reducing activities. We show that the private firm's cost becomes lower than the public firm's because the private firm engages in excessive strategic cost-reducing activities. Even though each firm's cost is heterogenous, the locations of the firms are socially efficient, given the cost differentials. Privatization of the public firm would improve welfare because it mitigates the loss due to excessive cost-reducing investments.
