This paper develops a novel procedure for proxying economic activity with day-time satellite imagery across time periods and spatial units, for which reliable data on economic activity are otherwise not available. In developing this unique proxy, we apply machine-learning techniques to a...

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....

It has traditionally been argued that the development of telecommunications infrastructure is dependent on the quality of countries' political institutions. We estimate the effect of political institutions on the diffusion of three telecommunications services and find it to be much smaller in...

We investigate whether excessively optimistic beliefs may play a role in the persistent demand for doctoral and post-doctoral training in science. We elicit the beliefs and career preferences of doctoral students through a novel survey and randomize the provision of structured information on the...

Using an RD-design and public educational administrative data for Chile, we study the impact of age of entry on children outcomes. Different from previous studies, we are able to track this impact on school achievements over eleven years of the school life of a cohort of students. Our results...

This paper studies aggregate dynamics in a cobweb model where learning takes place through a selection mechanism, by which more successful firms are replicated at a higher rate. The structure of the model allows to characterize analytically the aggregate dynamics, and to compute the effect on...

We estimate the impact of a differential treatment of paid employees versus self-employed workers in a public health insurance system on the entry rate into entrepreneurship. In Germany, the public health insurance system is mandatory for most paid employees, but not for the self-employed, who...

Many entrepreneurs start their ventures while retaining jobs in wage employment; this phenomenon is called hybrid entrepreneurship. Little is known about the entry modes (new venture start-up vs. business takeover) of hybrid entrepreneurs. Our study aims to close this gap by investigating the...

Using panel data from Spain Farinas and Ruano (IJIO 2005) test three hypotheses from a model by Hopenhayn (Econometrica 1992): (H1) Firms that exit in year t were in t-1 less productive than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent...

This paper examines causes of the low self-employment rates among Mexican-Hispanics by studying self-employment entry utilizing the 1996 panel of the Survey of Income and Program Participation (SIPP). The data show that Mexican-Hispanics are less likely to be self-employed as well as entering...
