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...

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....

This paper modifies the heterogenous firms and trade model by Melitz (2003) by explicitly modelling the entry cost of a firm in a new market as a function of market size. This leads to several new predictions compared to the standard model: The productivity of non exporters and exporters depends...

Using a large dataset covering all trade in military equipment over the period 1950-2007, we address the relationship between differences in polity and arms trade from a novel empirical perspective. We provide evidence on the determinants of link formation at the bilateral level by estimating...

Data on the growth performances of countries with similar comparative (dis)advantage and political institutions reveal a striking variation across world regions. While some former autocracies such as the East Asian growth miracles have done remarkably well, others such as the Latin American...

Recent theories of firm heterogeneity emphasize between-firm wage differences as a new mechanism through which trade can affect wage inequality. Using linked employer-employee data for Sweden, we show that many of the stylized facts about wage inequality found in Helpman et al. (2012) for Brazil...

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...

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...
