The welfare cost of imperfect competition in the product and labor markets in the United States is quantified in a dynamic general equilibrium model. We find that the welfare cost of imperfect competition in the product market is 3.62 percent while it is 0.58 percent in the labor market, taking the transition path from the distorted to the optimal steady state into account. If we also take into account that the US economy is characterized by distortionary taxation, the welfare cost of the product market distortion increases to 13.51 percent and the labor market distortion to 4.35 percent.
