Reducing tax evasion is a priority for many governments. A growing literature argues that verifying taxpayer reports against third-party information is critical for tax collection. However, effectiveness can be limited when tax authorities face constraints to credible enforcement and taxpayers make offsetting adjustments on other margins. We exploit a policy intervention in which Ecuadorian fir...

In repeated games with di®erential information on one side, the labelling \general case" refers to games in which the action of the informed player is not known to the uninformed, who can only observe a signal which is the random outcome of his and his opponent's action. Here we consider the problem of minimizing regret (in the sense ̄rst formulated by Hannan [8]) when the information available...

This paper examines the effect of leverage on the effectiveness of a self-financed taxsubsidy program offered by a government in stimulating a firm’s investment. We show that the firm, be it levered or unlevered, has an incentive to hasten its investment because of the agency conflicts arising from the commitment made by the government on the terms of the tax-subsidy program. We further show th...

This paper utilizes a novel database collected by the authors to document features of the progressivity of personal income tax systems across 209 countries for the years 1980-2009. We measure progressivity in several ways. First, we associate it with the increase in effective average (marginal) tax rates between a wage of zero and ten times the average wage in a country. Second, we consider the...

This paper analyzes how corporate capital gains taxes affect the capital gain realization decisions of firms. The paper outlines the tax treatment of corporate capital gains, the consequent incentives for firms with gains and losses, the efficiency consequences of these taxes in the context of other taxes and capital market distortions, and the response of firms to these incentives. Despite rec...

In a recent working paper, Plesko (1999) uses confidential tax return data to evaluate alternative measures of corporate average and marginal tax rates and concludes “The results suggest that commonly used measures of average tax rates provide little insight about annual corporate tax burdens, and may introduce substantial bias into statistical models. Marginal tax rate proxies perform better, ...

In the U.S. business income is taxed several times at different sources, including corporate income, dividends, capital gains, and interest payments. We investigate how the different rates above affect firm investment and the allocation of capital in the economy. To do so, we construct and calibrate a model with heterogeneous firms, borrowing constraints, costly equity issuance and endogenous e...

This paper analyses the impact of the corporate tax reform introduced in Italy at the beginning of 2004 on firms’ tax burden. For this purpose we develop a microsimulation model reproducing the Italian corporate tax system. The model is based on an integrated dataset combining ISTAT (Italian Institute of Statistics) survey data on enterprises and company accounts, for the year 2000. The empiric...
