Measuring the Effects of Economic Diversity on Growth and Stability
研究了经济多样性对区域稳定性和增长的作用，提出基于投入产出模型的新多样性衡量方法，发现该理论框架下的多样性与更高的稳定性和增长相关。
The role of economic diversity in regional stability and growth is examined. Contrary to "conventional wisdom" the empirical literature has been unable to confirm the link between diversity and economic performance. Traditional notions of diversity tend to be defined narrowly, usually emphasizing the distribution of employment across industries. These approaches are inadequate because they do not capture elements of inter-industrial linkages. An alternate approach to conceptualizing diversity, based on a regional input-output model, is described and computed for the 50 states. Empirical results suggest that diversity within the theoretical construct of input-output is associated with higher levels of stability and growth.
