| Abstract: | We extend marginal excess burden (MEB) analysis in public finance literature to a dynamic general equilibrium model with incomplete markets and heterogeneous households. This extension allows us to quantitatively assess efficiency ranking and incidence of taxes. Our results indicate a disparity in welfare cost and distributional consequence of different forms of taxation on capital, labor and consumption. According to our MEB ranking, capital income taxation appears to be least efficient as it results in larger marginal excess burdens, compared to labor income tax and consumption tax. The tax incidence analysis shows variation of tax burdens across households, depending on their age, income type and generation. In particular, older households with higher income bear the highest burden of company income tax; meanwhile, future born households bear the highest burden of personal income tax. Hence, our MEB analysis demonstrates a fruitful approach to better understanding efficiency and incidence of tax reforms in one unified framework. |
