Job-Market signaling is ranked high among the explanations why in- dividuals engage voluntarily in OSS projects. If true, signaling implies the existence of a wage premium for OSS engagement. However, due to a lack of data this issue has not been tested previously. Based on a novel data set...

This paper studies how removing barriers to competition in the nontraded goods sector affects the current account, the real exchange rate, and factor prices in a small open economy. We show that the expansion of the nontraded sector that results from a "deregulation shock" is associated with an...

We use a dynamic general-equilibrium model to study how removing barriers to competition in the nontraded goods sector affects the current account of a small open economy. We show that the expansion of the nontraded sector that results from such a "deregulation shock" is associated with an...

Reexamining foreign direct investment (FDI) as a potential channel for knowledge diffusion - based on industry data from seventeen OECD countries during the period 1973-2000 - we find that FDI-receiving countries benefit strongly from FDI-related knowledge spillovers. We do not find evidence for...

Our paper decomposes knowledge-diffusing trade flows and estimates their impacts separately. Overall, trade generates positive knowledge spillovers, but the effects of intra-industry trade are ambiguous. With regard to sectoral import penetration, we find that potential positive spillovers are...

This papers sheds light on the puzzling evidence that even though open source software (OSS) is a public good, it is developed for free by highly qualified, young and motivated individuals, and evolves at a rapid pace. We show that once OSS development is understood as the private provision of a...

This paper explores the role of immigrant employees for a firm's capability to absorb international knowledge. Using matched employer-employee data from Denmark for the years 1999 to 2009, we are able to show that non-Danish employees from technological advanced countries contribute...
