Operationalizing the Entrepreneurial Pipeline Theory: An Empirical Assessment of the Optimal Size Distribution of Local Firms

This article analyzes the relationship between local economic growth and the distribution of businesses across size categories. The distribution is measured by the employment share in businesses of various sizes and by a business distribution index. The index provides a measure of the extent to which the local economy deviates from an equal employment share in each of nine business-size categories. The authors find strong links between a countys business-size distribution and its economic growth rate and also a difference between the optimal income and job growth-enhancing distributions. In addition, the results indicate that the optimal growth-enhancing distribution of employment has a higher share of the smallest businesses (with one to four employees) than the current average. The results support increased policy emphasis on encouraging small business start-ups and development; however, the optimal development strategy depends on the initial distribution of businesses within a local economy.

Are mega-farms the future of global agriculture? Exploring the farm size-productivity relationship for large commercial farms in Ukraine

With farms cultivating tens or hundreds of thousands of hectares, Ukraine is often used to demonstrate the existence of economies of scale in modern grain production. Panel data analysis for all the countrys farms with more than 200 hectares in 2001-2011 suggests that higher yields and profits are due to unobserved factors at rayon (district) and farm level rather than economies of scale. Productivity growth was driven not by farm expansion but by exit of unproductive and entry of more efficient farms. Higher initial shares of area under farms with more than 3,000 or 5,000 hectares at the rayon level significantly reduce subsequent exit, suggesting that land concentration reduces productivity growth. The paper draws implications for global evolution of farm structures.
