摘要

我研究的是公共投资的永久扩张对提高长期生产率的刺激效应。通过对劳动力需求的预期效应，政策变化已经在短期内增加了就业。在一个搜索匹配劳动力市场的模型中，我分析了公共投资的就业乘数，并表明它在衰退时期比繁荣时期更大。以美国为基准进行校准后，该模型得出的结论是，在公共投资永久性增长占GDP的1%之后，就业一年将增加0.26个百分点。预期效应占就业增长的65%。

The short-run employment effects of public infrastructure investment

I study the stimulus effects of a permanent expansion of public investment that improves long-run productivity. Through an anticipation effect on labor demand, the policy change raises employment already in the short-run. In a model with search and matching labor market, I characterize the employment multiplier of public investment analytically and show that it is larger in a recession than a boom. Calibrated to the US, the model yields an increase in employment of 0.26 percentage points one year after a permanent expansion of public investment by 1% of GDP. The anticipation effect accounts for 65% of the employment gain.

期刊介绍： The European Economic Review (EER) started publishing in 1969 as the first research journal specifically aiming to contribute to the development and application of economics as a science in Europe. As a broad-based professional and international journal, the EER welcomes submissions of applied and theoretical research papers in all fields of economics. The aim of the EER is to contribute to the development of the science of economics and its applications, as well as to improve communication between academic researchers, teachers and policy makers across the European continent and beyond.
