Risk Aversion Sensitive Real Business Cycles
研究了技术选择如何使生产在不同自然状态下替代，并依赖于状态依赖的风险厌恶，发现内生技术选择能抵消负面生产率冲击，增加投资波动性，并预测股票市场超额收益。
Technology choice allows for substitution of production across states of nature and depends on state-dependent risk aversion. In equilibrium, endogenous technology choice can counter a persistent negative productivity shock with an increase in investment. An increase in risk aversion intensifies transformation across states, which directly leads to higher investment volatility. In our model and the data, the conditional volatility of investment correlates negatively with the price-dividend ratio and predicts excess stock market returns. In addition, the same mechanism generates predictability of consumption growth and produces fluctuations in the risk-free rate. This paper was accepted by Gustavo Manso, finance.
