我们采取了一个现成的模型与金融摩擦和异质性,并研究映射从信贷紧缩,建模为冲击抵押品约束,简单的总楔。我们研究了这个模型的三个变体,它们的不同之处仅在于潜在的异质性。我们发现,在所有三个模型变量中,信贷紧缩表现为不同的楔形:效率,投资和劳动力楔形。此外,所有这三个模型的变体都有一个未失真的欧拉方程的企业所有者的总和。这些结果突出了使用代表性的代理模型,以确定商业周期波动的来源的局限性。
We take an off-the-shelf model with financial frictions and heterogeneity, and study the mapping from a credit crunch, modeled as a shock to collateral constraints, to simple aggregate wedges. We study three variants of this model that only differ in the form of underlying heterogeneity. We find that in all three model variants a credit crunch shows up as a different wedge: efficiency, investment, and labor wedges. Furthermore, all three model variants have an undistorted Euler equation for the aggregate of firm owners. These results highlight the limitations of using representative agent models to identify sources of business cycle fluctuations.
