Why do some firms adopt certain tax havens and how sensitive is the demand for tax havens? We address these questions by studying how the repeal of Section 936 tax credits affected firms with affiliates in Puerto Rico. We first describe the characteristics of US multinationals that were exposed...

We find that employee stock option deductions lead to large aggregate tax savings for Nasdaq 100 and S&P 100 firms and also affect corporate marginal tax rates. For Nasdaq firms, the median marginal tax rate is 31 percent when option deductions are ignored but falls to 5 percent when one...

This paper investigates the extent to which loss-offset constraints affect corporate tax incentives. Using data gathered from corporate annual reports, we estimate that in 1984 fifteen percent of the firms in the nonfinancial corporate sector had tax loss carryforwards. When weighted by their...

Puerto Rico operated as a tax haven under U.S. Internal Revenue Code (IRC) Section 936. Firms in the pharmaceutical industry accounted for approximately 50% of tax credits awarded and 20% of employment under the program. The U.S. Congress eliminated the tax exemption program in 2006, creating a...

Under current U.S. tax law, a distinction is made between gains and losses by businesses. Losses that must be "carried forward" are subject to two penalties: a loss of interest, and expiration after fifteen years. Previous examinations have focused on the higher expected tax payments such a tax...

This paper analyzes the links between corporate tax avoidance, the growth of high-powered incentives for managers, and the structure of corporate governance. We develop and test a simple model that highlights the role of complementarities between tax sheltering and managerial diversion in...

Two well-noted phenomena of recent decades are the increasing concentration of personal income and the declining rate of corporate profitability. This paper investigates to what extent these two trends have a common explanation extent these two trends have a common explanation-shifting of income...

It is often claimed that multinational firms avoid taxes by shifting income from high-tax to low-tax countries. Using a five year panel of data for two hundred large U.S. manufacturing firms, we find that U.S. tax liability, as a fraction either of U.S. sales or U.S. assets, is related to the...

This paper develops and tests the hypothesis that accounting rules mitigate the effect of tax policy on firm investment decisions by obscuring the timing of tax payments. I model a firm that maximizes a discounted weighted average of after-tax cash flows and accounting profits. I estimate the...

We investigate how the length of the net operating loss carryback period affects corporate liquidity and marginal tax rates. We estimate that extending the carryback period from two to five years, as recently proposed in President Obama's budget blueprint, would provide $19 ($34) billion of...
