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 entrants seem particularly drawn to areas with many smaller suppliers, as suggested by Chinitz (1961). Abundant workers in relevant occupations also strongly predict entry. These forces plus city and industry fixed effects explain between 60 % and 80 % of manufacturing entry. We use spatial distributions of natural cost advantages to address partially endogeneity concerns. 1.

This study explores the importance of tacit knowledge transfer for international technology diffusion by examining ethnic scientific communities in the US and their ties to their home countries. US ethnic research communities are quantified by applying an ethnic-name database to individual patent records. International patent citations confirm knowledge diffuses through ethnic networks, and manufacturing output in foreign countries increases with an elasticity of approximately 0.3 to stronger scientific integration with the US frontier. To address reverse-causality concerns, reduced-form specifications exploit exogenous changes in US immigration quotas. Consistent with a model of sector reallocation, output growth in less developed economies is facilitated by employment gains, while more advanced economies experience sharper increases in labor productivity. The findings suggest tacit knowledge channels partly shape the effective technology frontiers of developing economies.

Firms and workers are much more productive in large and dense urban environments. There is substantial evidence of such agglomeration economies based on three aproaches. First, on a clustering of production beyond what can be explained by chance or comparative advantage. Second, on spatial patterns in wages and rents. Third, on systematic variations in productivity with the urban environment. However, more needs to be learned about the causes of agglomeration economies. We have good models of agglomeration through sharing and matching, but not a deep enough understanding of learning in cities. Despite recent progress, more work is needed to distinguish empirically between alternative causes.

This article examines the role of regional clusters in regional entrepreneurship. We focus on the distinct influences of convergence and agglomeration on growth in the number of start-up firms as well as in employment in these new firms in a given region-industry. While reversion to the mean and diminishing returns to entrepreneurship at the region-industry level can result in a convergence effect, the presence of complementary economic activity creates externalities that enhance incentives and reduce barriers for new business creation. Clusters are a particularly important way through which location-based complementarities are realized. The empirical analysis uses a novel panel dataset from the Longitudinal Business Database of the Census Bureau and the US Cluster Mapping Project. Using this dataset, there is significant evidence of the positive impact of clusters on entrepreneurship. After controlling for convergence in start-up activity at the region-industry level, industries located in regions with strong clusters (i.e. a large presence of other related industries) experience higher growth in new business formation and start-up employment. Strong clusters are also associated with the formation of new establish-ments of existing firms, thus influencing the location decision of multi-establishment firms. Finally, strong clusters contribute to start-up firm survival.

We study the long run effects of one of the most ambitious place based eco-nomic development policies in U.S. history: the Tennessee Valley Authority. We first conduct an evaluation of the dynamic effects of the TVA on local economies in the six decades since its inception. We find that TVA led to short run gains in agricultural employment that were eventually reversed, while impacts on man-ufacturing employment continued to intensify well after the program had scaled down. This pattern is potentially consistent with the presence of strong agglomer-ation economies and multiple steady states in the manufacturing sector. However, it is also consistent with models with a unique steady state and slow adjustment. To differentiate between these two possibilities, we estimate a simple dynamic county level model of agglomeration that allows for multiple steady states. We find clear evidence of agglomeration effects, but no sign that these effects are strong enough to generate multiple steady states, suggesting that the gains to the TVA region will eventually be reversed. Moreover, we find little evidence of nonlinearity in agglomeration economies, implying the aggregate productivity effects of place based development policies are probably limited.

We estimate the factors determining specialization of crop choice at the level of individual fields, distinguishing between the role of natural advantage (soil characteristics) and economies of density (scale economies achieved when farmers plant neighboring fields with the same crop). Using rich geographic data from North Dakota, including new data on crop choice collected by satellite, we estimate the analog of a social interactions econometric model for the planting decisions on neighboring fields. We find that planting decisions on a field are heavily dependent on the soil characteristics of the neighboring fields. Through this relationship, we back out the structural parameters of economies of density. Setting an Ellison-Glaeser dartboard level of specialization as a benchmark, we find that of the actual level of specialization achieved beyond this benchmark, approximately two-thirds can be attributed to natural advantage and one-third to density economies.

Geographically concentrated industry activity creates pools of skilled labor and specialized suppliers, and increases opportunities for knowledge spillovers. The strategic value of these agglomeration economies may vary by firm, depending upon the relative value of each economy, and upon firm and agglomeration economy traits. To better determine when a firm will be attracted to agglomeration economies, we develop a three-layer framework. The first layer assesses the relative importance of skilled labor, suppliers, and knowledge spillovers. The second layer considers whether firms can benefit from geographic concentration without co-locating. The final layer examines why some firms are more inclined to co-locate than others based upon firm and agglomeration economy traits. We test our framework on the U.S. location choices of new manufacturing entrants between 1985 and 1994 and find that firms are far more attracted to skilled labor and specialized suppliers than they are to potential knowledge spillovers, even in R&D intensive industries. We also find that leading firms will be more attracted to pools of labor, suppliers, and potential knowledge spillovers when their own contributions are less fungible, and cannot be easily leveraged for strategic advantage by proximate competitors.
