Economic Diversity And Regional Economic Performance: A Methodological Concern From Model Uncertainty, Jing Chen
Regional Research Institute Working Papers
Although the role of spatial dependence has been considered in studying the relationship between economic diversity and regional economic performance, the existing literature seldom mentions model uncertainty, which mainly arises from at least two sources. One source of model uncertainty is the choice of an appropriate spatial weight matrix that describes the spatial interactions between two regions, which can be specified in a variety of ways. The second source of model uncertainty is choosing a set of control variables to model the diversityperformance relationship. To overcome these limitations, a Bayesian Model Averaging (BMA) method is used to address model uncertainty …
Interpreting Economic Diversity As The Presence Of Multiple Specializations, Jing Chen
Interpreting Economic Diversity As The Presence Of Multiple Specializations, Jing Chen
Regional Research Institute Working Papers
Conventional wisdom indicates that economic specialization can promote economic growth, whereas economic stability is theoretically associated with diversified economies. This conflicting relationship between specialization and diversity has been questioned, as regional scientists have suggested that specialization and diversity can coexist in a regional economy and proposed the concept of diversified specializations. To test this proposition empirically, three Herfindahl Hirschman Indices measuring regional economic diversity were used to examine the relationship between economic structure and regional economic performance among 359 metropolitan statistical areas (MSA) in the contiguous U.S. The first index measures economic diversity across 87 three-digit North American Industry Classification …
