Project Details
Description
We solve a multi-dimensional and dynamic model where individuals differ alongtwo dimensions: productivity and Frisch elasticity of labor supply. We decomposethe optimal capital tax formula into two components. Firstly, the social plannerprefers to tax capital income because, with a concave utility function, anindividual who saves more in period t will choose to work less in period t + 1 inresponse. This effect is in line with the literature of New dynamic public finance(NDPF). Secondly, the optimal capital tax rate is also determined by the ratio ofexpected informational rent tomorrow relative to informational rent today. If thetype i enjoys less informational rent in period t than that in period t+1, the socialplanner lowers type i’s capital tax rate. This effect leads to a progressive taxschedule on capital income. More importantly, this novel effect is only present ina multi-dimensional case.
