How much does US-based R&D benefit other countries and through what mechanisms? We test the 'technology sourcing' hypothesis that foreign research labs located on US soil tap into US R&D spillovers and improve home country productivity. Using panels of UK and US firms matched to patent data we...

We document a robust relation between corporate tax differentials and US international financial integration (IFI). While this is the case for traditional IFI based on cross-border positions, the positive link also emerges for its larger consolidated-by-nationality version. The gap between these...

This paper investigates the causes of the shortfall in private R&D expenditure of the EU compared to the US. It shows that differences in the structure of the two economies play only a minor role in explaining the R&D gap. Instead, the European R&D shortfall is mainly caused by a negative...

We study the prevalence and traits of global collaborative patents for U.S. public companies, where the inventor team is located both within and outside of the United States. Collaborative patents are frequently observed when a corporation is entering into a new foreign region for innovative...

This paper studies the impact that ethnic innovators have on the global activities of U.S. firms by analyzing detailed data on patent applications and on the operations of the foreign affiliates of U.S. multinational .rms. The results indicate that increases in the share of a firm's innovation...

We present a heterogeneous-firm model in which management ability increases both pro- duction efficiency and product quality. Combining six micro-datasets on management practices, production and trade in Chinese and American firms, we find broad support for the model's predictions. First, better...

Immigrants account for about a quarter of US invention and entrepreneurship despite a policy environment that is not well suited for these purposes. This chapter reviews the U.S. immigration policy environment that governs how skilled migrants move to America for employment-based purposes. We...
