Risk premiums in asset prices and returns
回顾了时变风险溢价的最新研究，包括解释无偏假设被拒绝的尝试，利用即期和远期汇率讨论证据，联系一般均衡资产定价理论，并描述人工经济方法。
We review recent research on time-varying risk premiums, including attempts to explain rejections by baillie and others of the unbiasedness hypothesis. Using spot and forward foreign exchange rates we discuss the evidence for time-varying risk premiums, relate it to general equilibrium theories of asset pricing, and describe the artificial economy methodology.
