摘要

本研究评估了能源中断和内部发电机对大约12 000家非洲公司的产能利用的影响。能源中断和内部发电机分别由公司经历能源中断的天数和自产电力占总电力消耗的比例来衡量。我们进一步根据停电天数和自产电力份额构建分位数假人。估计结果取决于对这些关键变量的测量，以及是否考虑了能源中断和内部发电机的共同影响。例如，只有在包含停电天数、自产电量份额和它们之间的交互项的模型中，才会发现停电天数和共同影响都是显著的。本研究全面评估了停电和发电机所有权对容量利用率的影响，提供了有价值的管理和政策见解。

Energy outages, in-house power generators, and capacity utilization: The case of African manufacturing

This study evaluates the impact of energy outages and in-house power generators on capacity utilization among approximately 12,000 African firms. Energy outages and in-house power generators are measured by the days that firm experienced energy outages and the share of self-generated electricity as a proportion of total electricity consumed, respectively. We further construct quantile dummies based on outage days and the self-generated electricity share. The estimation results depend on the measurement of these key variables and whether the joint impact of energy outages and in-house power generators is accounted for. For example, only in the model that include outage days, the self-generated electricity share, and the interaction term between them, both outage days and the joint impact are found to be significant. This study provides a comprehensive assessment of the effects of power outages and generator ownership on capacity utilization, offering valuable managerial and policy insights.

期刊介绍： Energy Economics is a field journal that focuses on energy economics and energy finance. It covers various themes including the exploitation, conversion, and use of energy, markets for energy commodities and derivatives, regulation and taxation, forecasting, environment and climate, international trade, development, and monetary policy. The journal welcomes contributions that utilize diverse methods such as experiments, surveys, econometrics, decomposition, simulation models, equilibrium models, optimization models, and analytical models. It publishes a combination of papers employing different methods to explore a wide range of topics. The journal's replication policy encourages the submission of replication studies, wherein researchers reproduce and extend the key results of original studies while explaining any differences. Energy Economics is indexed and abstracted in several databases including Environmental Abstracts, Fuel and Energy Abstracts, Social Sciences Citation Index, GEOBASE, Social & Behavioral Sciences, Journal of Economic Literature, INSPEC, and more.
