In this research project, we study boom-bust cycles in housing and credit markets that are driven by economic fundamentals andamplified by financial market imperfections. In particular, we ask to what extent government policy (tax policy) and financial innovation contribute to the occurrence of boom-bust cycles in economies with two financial market imperfections: limited contract enforcement and incomplete markets. To this end, we first develop a micro-founded macroeconomic model with heterogeneous households and these two financial frictions. We use a version of the model economy calibrated to the US data to simulate the quantitative impact of changes in government policy and financial innovation on the cyclical variations in house prices, household debt, default rates, and other macroeconomic variables. We also consider a second version of the model calibrated to German data and German institutions and conduct a comparative analysis between the US and Germany. Finally, we discuss the distributional consequences of changes ingovernment policy and financial innovation and their effect on longrun economic growth, with a special emphasis on the human capitalchannel.

在这个研究项目中，我们研究了房地产和信贷市场的繁荣-萧条周期，这些周期是由经济基本面驱动的，并被金融市场的不完善放大。特别是，我们问政府政策（税收政策）和金融创新在多大程度上有助于经济体的繁荣-萧条周期的发生与两个金融市场的不完善：有限的合同执行和不完整的市场。为此，我们首先建立了一个微观基础的宏观经济模型，异质家庭和这两个金融摩擦。我们使用一个根据美国数据校准的经济模型来模拟政府政策和金融创新的变化对房价、家庭债务、违约率和其他宏观经济变量的周期性变化的量化影响。我们还考虑了第二个版本的模型校准到德国的数据和德国的机构，并进行比较分析之间的美国和德国。最后，我们讨论了政府政策变化和金融创新的分配后果及其对长期经济增长的影响，特别强调了人力资本渠道。
