We propose a simple explanation for the long-run decline in the startup rate. It was caused by a slowdown in labor supply growth since the late 1970s, largely pre-determined by demographics. This channel explains roughly two-thirds of the decline and why incumbent firm survival and average...

We study how a mortgage reform that exogenously increased access to credit had an impact on entrepreneurship, using individual-level micro data from Denmark. The reform allows us to disentangle the role of credit access from wealth effects that typically confound analyses of the collateral...

This paper develops a game-theoretic model that predicts when a university invention is commercialized in a start-up firm rather than an established firm. The model predicts that university inventions are more likely to occur in start-ups when the technology transfer officers (TTOs) search cost...

While official measures of business dynamism have seen a long-term decline, early-stage venture financing of new companies has reached levels not observed since the late 1990s, resulting in a sharp debate about the state of American entrepreneurship.

We study whether this reform affects the composition of people who are drawn into entrepreneurship. New firms started in response to the reform are, on average, smaller,...

After the new plant opening, incumbent plants in winning counties experience a sharp relative increase in TFP. Five years after the opening, TFP of incumbent plants in winning counties is 12% higher than TFP of incumbent plants in losing counties. Consistent with some theories of agglomeration,...
