In this chapter, we explore the extent to which universities and other nonprofit research institutes currently participate in the secondary market for patents. We document 220 assignments, involving a total of 544 U.S. patent assets, that appear to represent arms-length patent sales by...

In light of the United Nations' (UN) latest urbanization projections, par- ticularly with respect to India and the People's Republic of China, a good understanding is needed of what drives aggregate urbanization trends. Yet, previous literature has largely neglected the issue in favor of...

We use US county level data (3,058 observations) from 1970 to 1998 to explore the relationship between economic growth and the extent of government employment at three levels: federal, state and local. We find that increases in federal, state and local government employments are all negatively...

We use U.S. county-level data to estimate convergence rates for 22 individual states. We find significant heterogeneity. E.g., the California estimate is 19.9 percent and the New York estimate is 3.3 percent. Convergence rates are essentially uncorrelated with income levels. -- Economic Growth ;...

Recent literatures on entrepreneurship and economic growth estimate the empirical relationships between the following pairs of variables: (1) institutions and entrepreneurial activity; (2) institutions and economic growth; and (3) entrepreneurship and economic growth.This paper revisits each of...

This paper contributes to the literature that uses the Economic Freedom of North America (EFNA) index to evaluate relationships with various outcomes. Most of the literature estimates a linear relationship between economic freedom and those outcomes. However, using matching methods can be a...

This paper examines U.S. per capita income convergence in 1929-2002 using a panel approach based on the assumptions of multiple aggregate structural breaks and growth clubs. One novelty is that our specification explicitly allows for regional conditional convergence to the nation, while at the...

We utilize county-level data to explore the roles of different types of human capital accumulation in U.S. growth determination. The data includes over 3,000 cross-sectional observations and 39 demographic control variables. The large number of observations provides enough degrees of freedom to...

The historical analysis of US regional growth is improved by augmenting existing estimates of state personal income per capita, extending previous studies of convergence across states, and more broadly, offering an improved basis for interpreting other issues in regional development such as the...
