摘要
This paper estimates the incidence of corporate income tax for small firms, using the discontinuous cut of the tax rate for small firms. We first document that firms bunch blow the threshold. We employ the donut-hole regression discontinuity method to estimate the causal impact of the tax cut. We find in the short run, all the tax cut benefit went to the investment, and there was no significant increase in wages, workers' other benefits, and number of workers. The elasticity of investment with respect to the cash saved by tax-cut is larger than 1, probably because of the increase in after-tax rate of return. The increase in investment was financed by lower retained profits and more debt. Although firm size and productivity did not increase immediately due to the tax cut, there were some evidences for the growth in firm size and productivity in the second year of the tax cut. Wages also grow faster in the second year, due to more investment in the first year. Our results imply that firms invest almost all the cash saved in the tax cut to develop business, and works can share the benefits only in the long run.
