Misallocation and aggregate productivity across time and space
探讨了不同国家间投入要素在异质性生产单位间的配置差异（即错配）如何影响总生产率，指出导致错配的政策和制度在贫困和发展中国家普遍存在，并可能解释跨国生产率差异。
Abstract Productivity is at the core of the large differences in income per capita across countries. What accounts for international productivity differences? I discuss cross‐country differences in the allocation of inputs across heterogeneous production units—misallocation—as a potential factor in accounting for aggregate productivity. Policies and institutions generating misallocation are prevalent in poor and developing countries and may also be responsible for differences in the selection of operating producers and technology used, contributing substantially to aggregate productivity differences across countries.
