The US government taxes the foreign income of American firms, using a system that grants credits for foreign taxes paid and permits tax deferral for unrepatriated income. This paper shows that the tax system encourages firms to restrict their equity stakes in new foreign investments, and to...

We estimate and attempt to explain the evolution of the taxes paid by U.S. multinationals on their foreign profits since 1966. In the oil sector, taxes paid to oil-producing States have been contained, allowing U.S. firms to earn high after-tax returns. Foreign taxes fell abruptly after the...

This paper analyzes the effects of the U.S. tax treatment of the R&D activities of American multinationals. Recent evidence indicates that the level of R&D spending is highly sensitive to its after-tax cost. The U.S. Tax Reform Act of 1986 reduced the tax deductions that many American firms can...

This paper examines the impact of the 1986 change in U.S. interest allocation rules on the investment and financing decisions of American multinationals. The 1986 change reduced the tax deductibility of the interest expenses of firms with excess foreign tax credits. The resulting increase in the...

This paper explores the effect of recent U.S. tax changes on the R&D activities of American multinational corporations. Prior to 1986, U.S. multinational firms could deduct all of their domestic R&D expenses against their U.S. income for tax purposes. After 1986, some firms could take only a...

Within Japanese multinational firms, parent exports from Japan to a foreign region are positively related to production in that region by affiliates of that parent, given the parent's home production in Japan and the region's size and income level. This relationship is similar to that found for...

We use firm-level data on U.S. multinationals to show how offshoring affects domestic employment within and across firms. We introduce a new instrument for offshoring: Bilateral Tax Treaties, which reduce the cost of offshore activities. We find substantial heterogeneity in effects. A 10 percent...

The U.S. Bureau of Economic Analysis (BEA) estimates the return on investments of foreign subsidiaries of U.S. multinational companies over the period 1982--2006 averaged 9.4 percent annually after taxes; U.S. subsidiaries of foreign multinationals averaged only 3.2 percent. Two factors distort...

We use firm-level data for U.S. multinational enterprises (MNE) and the model of firm heterogeneity first presented in Helpman, Melitz, and Yeaple (2004) to make four empirical contributions. First, we show that the most productive U.S. firms invest in a larger number of foreign countries and...

The last 20 years have been marked by a sharp rise in international demand for U.S. reserve assets, or safe stores-of-value. What are the welfare consequences to U.S. households of these trends, or of a reversal? In a lifecycle model with aggregate and idiosyncratic risks, the young and oldest...
