Using SIPRI data on all international transfers of major conventional weapons 1950–2007, we study the relationship between differences in polity and arms trade. To study whether states tend to trade arms within their political vicinity we estimate gravity models of the likelihood of trade at...

Does adoption of broadband internet in firms enhance labor productivity and increase wages? And is this technological change skill biased or factor neutral? We exploit rich Norwegian data with firm-level information on value added, factor inputs and broadband adoption to answer these questions....

With about 1/5th of all jobs changing each year, labor mobility is a potentially significant source for idea exchange in the economy. In this paper, we analyze the effect of labor mobility and innovation on productivity growth in the economy. First, by leveraging administrative data for Sweden,...

Using highly granular micro data, we document very divergent economic effects of the COVID-19 pandemic on Swedish private-sector firms and their workers. Firms that exported to, or imported from, heavily afflicted countries reduced their output due to disrupted trade. Service firms that operated...

We show theoretically and empirically that standard methods give downward biased estimates of productivity growth if technical change is factor-biased. We show how to correct for this bias and construct more reliable measures of the productivity gains from technical progress. We consider two...

This paper introduces a market size dependent firm entry cost into the Helpman, Melitz and Yeaple (2004) (HMY) version of the Melitz (2003) model. This is a relatively small generalisation, which preserves the analytical solvability of the model. Nevertheless, our model yields several new...

Does adoption of broadband internet in firms enhance labor productivity and increase wages? And is this technological change skill biased or factor neutral? We exploit rich Norwegian data to answer these questions. A public program with limited funding rolled out broadband access points, and...
