We theoretically investigate the interaction of endogenous risk intolerance and monetary policy following a large recessionary shock. As asset prices dip, risk-tolerant agents’ wealth share declines. This decline reduces the market’s risk tolerance and triggers a downward loop in asset prices and aggregate demand when the interest rate policy is constrained. In this context, large-scale asset purchases are effective because they transfer unwanted risk to the government’s balance sheet. These effects are sizable when the model is calibrated to match the estimates of aggregate asset demand inelasticity. The COVID-19 shock illustrates the environment we seek to capture.

内源性风险承受力和LSAP的模型:“ COVID-19”冲击中的资产价格和总需求

我们从理论上研究了内在的风险不容忍与大规模衰退冲击后的货币政策之间的相互作用。随着资产价格下跌,风险承受能力的经纪人的财富份额下降。当利率政策受到约束时,这种下降会降低市场的风险承受能力,并引发资产价格和总需求的下降循环。在这种情况下,大规模购买资产是有效的,因为它们会将不必要的风险转移到政府的资产负债表中。当模型进行校准以匹配总资产需求无弹性的估计时,这些影响是相当大的。COVID-19的冲击说明了我们寻求捕获的环境。
