The Social Loss from Imperfect Competition: The Case of the Swedish Pulpwood Market
通过计量分析将瑞典圆木市场分为锯材和纸浆木材两个子市场，量化纸浆木材市场从寡头合作转向完全竞争后的社会福利变化，发现竞争将导致纸浆产业扩张而锯木产业收缩。
In this econometric analysis, the Swedish roundwood market is divided into two submarkets: the sawtimber market, which consists of many buyers and sellers, and the pulpwood markets, which consists of few buyers who collaborate in purchasing cartels. The two markets are interrelated through cross-price effects. The main issue is to quantify the effects on social welfare if the pulpwood market were competitive. The results show that a competitive pulpwood market should bring about a shift in the market structure in the sense that the pulp industry would expand its capacity at the expense of the sawmill industry.
