Economics

There are three chapters in my dissertation. In chapter one I study the impact of govern-ment corruption on tax avoidance by corporations with tax liability in China. I begin by developing a model of a firm’s choice of tax avoidance based on the level of corruption in the firm’s province. I show that a higher level of government corruption and a higher tax rate are predicted to increase a firm’s tax avoidance. My empirical estimates show that a one-standard-deviation increase in gov-ernment corruption corresponds to a 6 % increase in tax avoidance by firms, based on data from nearly 600,000 firms from 1998 to 2007. When I separate the sample by type of ownership of firms, I find that domestic private firms tend to avoid a larger portion of their tax liabilities than foreign or state-owned firms. I also find that tax avoidance increases when the effective tax rate increases. The size of the firm, age of the firm, and whether the firm exports from China also influence tax avoidance. In chapter two, a joint work with Sergey Mityakov, we study the impact of competition on tax avoidance by corporations in Mexico. Using more than 2,000 firm level data, we show that firms tend to avoid more taxes in less competitive markets, that is more concentrated market. A one standard deviation increase in competition leads to a 7.7 % increase in tax avoidance. By splittin
