Junior is rich: bequests as consumption
研究了在世代交叠经济中引入遗产动机对资产定价的影响，发现低风险厌恶下模型能产生合理的股权溢价均值、无风险利率和遗产财富比，但无风险利率方差过高。
We explore the consequences for asset pricing of admitting a bequest motive into an otherwise standard overlapping generations economy where agents trade equity, a risk free asset and consol bonds. With low risk aversion, the calibrated model produces realistic values for the mean equity premium and the risk free rate, the variance of the equity premium, and the ratio of bequests to wealth. However, the variance of the risk free rate is unrealistically high. Security prices tend to be substantially higher in an economy with bequests as compared to an otherwise identical one where bequests are absent. We are able to keep the prices sufficiently low to generate reasonable returns and premia by stipulating that a portion of the bequests skips a generation and is received by the young. “You never actually own a Patek Philippe.
