Price Leadership and Welfare Losses in U.S. Manufacturing: Reply
利用价格领导模型估计美国制造业垄断造成的福利损失，基于445个四位数行业的样本，发现无谓损失占GNP的0.114%，支持了Harberger三十年前的结论。
A model of price leadership is used to estimate the welfare losses dueto monopoly in U.S. Manufacturing. Given that the leaders behave independently, an hypothesis confirmed empirically, the deadweight lossis estimated at 0.114 percent of GNP based on a sample of 445 four-digit industries. This estimate lends strong support to Arnold C.Harberger's finding of thirty years ago. Copyright 1986 by American Economic Association.
