Active Private Sector Development Policies Revisited: Impacts of the Ethiopian Industrial Cluster Policy
研究埃塞俄比亚工业集群政策对企业增长的影响，发现该政策破坏了企业商业和知识网络、降低了信任、增加了交易成本，对就业创造和企业绩效产生负面效应。
We analyse impacts of a cluster policy aiming to increase firm growth through maximising agglomeration benefits and improving production facilities. Firms located in a natural cluster were incentivised to move to a new government-created cluster. A limited number of firms were allowed to move, and many similar firms, also eager to move but could not, formed our comparison group. Controlling for selection, and employing difference in-difference estimation, we find large negative effects on job-creation and firm performance. The policy hampered the firms’ business and knowledge networks, reduced trust among firms, increased transaction costs and curbed market information.
