This chapter reviews the concepts, methods, and results of studies that analyze the incidence of taxes. The purpose of such studies is to determine how the burden of a particular tax is allocated among consumers through higher product prices, workers through a lower wage rate, or other factors of production through lower rates of return to those factors. The methods might involve simple partial equilibrium models, analytical general equilibrium models, or computable general equilibrium models. In a partial equilibrium model, the burden of a tax is shown to depend on the elasticity of supply relative to the elasticity of demand. Partial equilibrium models also are used to consider cases with imperfect competition. In a two-sector general equilibrium model, a tax might be imposed on either commodity, on either factor of production, or on a factor used in one sector. The original use of this model is to analyze the corporate income tax as a tax on capital used only in one sector, the corporate sector. The model can be used to show when the burden falls only on capital or when the burden is shared with labor. The model also has been applied to the property tax, and results of the model have been used to calculate the overall burden on each income group. Because the total stock of capital is fixed in that model, however, dynamic models are required to show how a tax on capital affects capital accumulation, future wage rates, and overall burdens. Such models might also provide analytical results or computational results. The most elaborate recent models calculate the lifetime incidence of each group. Finally, the chapter reviews the use of such incidence methods and results in the policy process.
