摘要

许多政策制定者将停电视为发展中国家企业生产力的主要制约因素。然而,实证研究发现,停电对企业绩效的短期影响不大。本文建立了一个动态宏观经济模型,研究了停电对生产率的长期一般均衡影响。中断通过创造闲置资源,抑制现有企业的规模和减少新企业的进入来降低模型中的生产率。与经验文献一致,该模型预测了消除停电的短期小影响。然而,长期的一般均衡效应要大得多,这支持了消除停电是一个重要发展目标的观点。(jel d22, d24, g32, l94, o13, o14)

Electricity and Firm Productivity: A General-Equilibrium Approach
Many policymakers view power outages as a major constraint on firm productivity in developing countries. Yet empirical studies find modest short-run effects of outages on firm performance. This paper builds a dynamic macroeconomic model to study the long-run general-equilibrium effects of power outages on productivity. Outages lower productivity in the model by creating idle resources, depressing the scale of incumbent firms and reducing entry of new firms. Consistent with the empirical literature, the model predicts small short-run effects of eliminating outages. However, the long-run general-equilibrium effects are much larger, supporting the view that eliminating outages is an important development objective. (JEL D22, D24, G32, L94, O13, O14)

期刊介绍: American Economic Journal: Macroeconomics focuses on studies of aggregate fluctuations and growth, and the role of policy in that context. Such studies often borrow from and interact with research in other fields, such as monetary theory, industrial organization, finance, labor economics, political economy, public finance, international economics, and development economics. To the extent that they make a contribution to macroeconomics, papers in these fields are also welcome.
