| Abstract: |
This dissertation consists of three essays studying the impacts of income and wage taxes. Chapter One examines how income tax changes differentially affect the pre-tax wages of different industries based on the injury and fatality rates of those industries. This chapter recognizes that compensating differentials are a function of the income tax rate and uses this observation to introduce a new methodology for estimating compensating differentials with a specific application to the estimation of the Value of a Statistical Life (VSL) parameter. When taxes change, the pre-tax wages of risky jobs should shift relative to the pre-tax wages of safe jobs in a manner proportional to the VSL. This strategy yields VSL estimates between $50 million and $75 million, an order of magnitude higher than the previous literature. Chapter Two studies the link between taxes and occupational choices. Just as taxes distort the labor-leisure decision, they also distort the wage-amenity decision. Few papers have isolated this effect. This chapter introduces a two-step estimation strategy to isolate the elasticity of occupation choice with respect to tax rates, testing whether workers select higher (lower) wage jobs when tax rates decrease (increase). The final estimates find a statistically significant overall compensated elasticity of 0.05, implying that a 10% increase in the net-of-tax rate causes workers to change to a job with a 0.5% higher wage. Chapter Three focuses on the tax elasticity of labor income. (cont.) Because governments can tax labor income separately from capital income, it is critical to isolate the tax elasticity of labor income. Furthermore, governments can use non-linear taxes so the mean elasticity :is not the relevant statistic. In this chapter, I introduce a new quantile estimator useful for panel data and applicable in an IV context. I find evidence of significant heterogeneity in the compensated elasticity. The importance of this heterogeneity is most evident for men as the elasticity is much larger at the top quantiles. The elasticity also appears to be larger at lower quantiles for both men and women. |
