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...

Clusters of Entrepreneurship

Glaeser, Edward Ludwig; Ponzetto, Giacomo A. M.; Kerr, … - National Bureau of Economic Research (NBER) - 2009

Employment growth is strongly predicted by smaller average establishment size, both across cities and across industries within cities, but there is little consensus on why this relationship exists. Traditional economic explanations emphasize factors that reduce entry costs or raise...

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...

The Geography and Channels of Diffusion at the World's Technology Frontier

Keller, Wolfgang - National Bureau of Economic Research (NBER) - 2001

Convergence in per capita income turns on whether technological knowledge spillovers are global or local. Global spillovers favor convergence, while a geographically limited scope of knowledge diffusion can lead to regional clusters of countries with persistently different levels of income per...

Trade and Transmission of Technology

Keller, Wolfgang - National Bureau of Economic Research (NBER) - 1997

We present a model of R&D-driven growth which predicts that technology, in the form of product designs and created through R&D investments, is transmitted to other domestic and foreign sectors by being embodied in differentiated intermediate goods. Empirical results are presented employing data...

Estimating the Productivity Selection and Technology Spillover Effects of Imports

Keller, Wolfgang; Acharya, Ram C. - National Bureau of Economic Research (NBER) - 2008

Economists emphasize two channels through which import liberalization affects productivity, one operating between and the other within firms. According to the former, import competition triggers market share reallocations between domestic firms with different technological capabilities...

Technology Transfer through Imports

Keller, Wolfgang; Acharya, Ram C. - National Bureau of Economic Research (NBER) - 2007

While there is general agreement that technology differences must figure prominently in any successful account of the cross-country income variation, not much is known on the source of these technology differences. This paper examines cross-country income differences in terms of factor...
