We compare unit and ad valorem commodity tax regimes under the "Leviathan hypothesis" that the government seeks to maximize tax revenue. We show that the ad valorem tax regime welfare-dominates the unit tax regime if and only if the economy exhibits "ad valorem under-shifting" in response to a...

The conventional wisdom is that a big jurisdiction sets a higher tax rate than a small jurisdiction. We show this result arises due to simplifying assumptions that imply tax-base sensitivities are equal across jurisdictions. When more than two jurisdictions compete in commodity taxes, tax-base...

This paper argues that the large reduction in corporate tax rates and only gradual widening of tax bases in many countries over the last decades are consistent with tougher international competition for foreign direct investment (FDI). To make this point we develop a model in which governments...

Die neuen Mitgliedstaaten der Europäischen Union haben ihre nominalen Körperschaftsteuersätze vor ihrem Beitritt stark reduziert. Vielfach wurde befürchtet, dass die geringeren nominalen Steuersätze von restriktiveren Verlustverrechnungsmodalitäten begleitet werden. Dies könnte zu einem...

While there is a large and growing number of studies on the determinants of corporate tax rates, the literature has so far ignored the fact that the behavior of governments in setting tax rates is often best described as a discrete choice decision problem. We set up an empirical model that...

In January 2014, Mexico addressed its epidemic of obesity by implementing an excise tax of 1 peso (1 MXN) per liter on soft drinks. This study evaluates the pass-through of the tax, the influence on the tax of competition among different stores, and the after-tax price dispersion. Using an...

We examine how tax cuts that benefit some firms are related to the economic performance of their direct competitors. Consistent with tax cuts decreasing the cost of initiating competitive strategies, we find that a decrease in the tax burden for only a specific group of firms in the U.S. economy...

This paper analyses the development of the ratio of corporate taxes to wage taxes using a simple political economy model with internationally mobile and immobile firms. Among other results, our model predicts that countries reduce their corporate tax rate, relative to the wage tax, either when...

This paper is concerned with a policy oriented macroeconomic experiment involving an 'international' economy with a relatively small 'home' country and a large 'foreign' country. It compares the economic performance of two alternative tax systems as a means to finance unemployment benefits: a...
