Local Industrial Conditions and Entrepreneurship: How Much of the Spatial Distribution Can We Explain?

Glaeser, Edward Ludwig; Kerr, William R. - National Bureau of Economic Research (NBER) - 2008

Why are some places more entrepreneurial than others? We use Census Bureau data to study local determinants of manufacturing startups across cities and industries. Demographics have limited explanatory power. Overall levels of local customers and suppliers are only modestly important, but new...

Agglomerative Forces and Cluster Shapes

Kerr, William R.; Kominers, Scott Duke - National Bureau of Economic Research (NBER) - 2010

We model spatial clusters of similar firms. Our model highlights how agglomerative forces lead to localized, individual connections among firms, while interaction costs generate a defined distance over which attraction forces operate. Overlapping firm interactions yield agglomeration clusters...

Entrepreneurship and Urban Growth: An Empirical Assessment with Historical Mines

Glaeser, Edward Ludwig; Kerr, Sari Pekkala; Kerr, William R. - National Bureau of Economic Research (NBER) - 2012

Measures of entrepreneurship, such as average establishment size and the prevalence of start-ups, correlate strongly with employment growth across and within metropolitan areas, but the endogeneity of these measures bedevils interpretation. Chinitz (1961) hypothesized that coal mines near...

Medium Term Business Cycles in Developing Countries

Comin, Diego; Loayza, Norman V.; Servén, Luis; Pasha, … - National Bureau of Economic Research (NBER) - 2009

We build a two country asymmetric DSGE model with two features: (i) endogenous and slow diffusion of technologies from the developed to the developing country, and (ii) adjustment costs to investment flows. We calibrate the model to match the Mexico-U.S. trade and FDI flows. The model is able to...

Comin, Diego; Gertler, Mark - National Bureau of Economic Research (NBER) - 2003

Over the postwar, the U.S., Europe and Japan have experienced what may be thought of as medium frequency oscillations between persistent periods of robust growth and persistent periods of relative stagnation. These medium frequency movements, further, appear to bear some relation to the high...

The Rise in Firm-Level Volatility: Causes and Consequences

Comin, Diego; PHILIPPON, Thomas - National Bureau of Economic Research (NBER) - 2005

We document that the recent decline in aggregate volatility has been accompanied by a large increase in firm level risk. The negative relationship between firm and aggregate risk seems to be present across industries in the US, and across OECD countries. Firm volatility increases after...
