Perfect Competition and the Effects of Energy Price Increases on Economic Activity
针对Rotemberg和Woodford关于能源价格上涨影响经济活动的证据，证明完全竞争理论也能解释这些现象，挑战了不完全竞争是必要条件的观点。
Rotemberg and Woodford (1996) present new striking facts concerning the effects of energy price increases on economic activity. They advance a theory of imperfect competition to successfully address these facts--suggesting that imperfect competition is a necessary ingredient for success. The present study shows that a theory of perfect competition rises to the challenge of explaining the Rotemberg-Woodford evidence.
