Population ecology models are elegant in form and adequate in describing aggregate data, but poor in telling stories and predicting the location of growth. Fundamentals models emphasizing the variables central to resource mobilization, such as intellectual human capital, can predict where and...

Scientists who make breakthrough discoveries can receive above- normal returns to their intellectual capital, with returns depending on the degree of natural excludability - that is, whether necessary techniques can be learned through written reports or instead require hands-on experience with...

Chinese rural industry has grown three times faster than national GDP, surpassing agriculture in size in 1987, and now nearing half of the total Chinese economy. We use a rich, new county-level data set to explore this dramatic growth. We find that a Cobb-Douglas production function explains...
