Decreasing relative risk premium
We consider the risk premium π demanded by a decision maker with present wealth x in order to be indifferent between obtaining a new level of wealth y1 with certainty, or to participate in a lottery which either results in unchanged wealth x or a level of wealth y2 > y1. We then define the relative risk premium λ as the quotient between π and the increase in wealth y1−x which the decision maker...
متن کاملThe Equity Premium Puzzle and the Risk-free Rate Puzzle
This paper studies the implications for general equilibnum asset pricing of a class of Kreps-Porteus nonexpected utility preferences characterized by a constant intertemporal elasticity of substitution and a constant, but unrelated, coefficient of relative risk aversion. It is shown that relaxing the parametric restriction on tastes imposed by the time-additive expected utility specification do...
متن کاملDecreasing Relative Risk Aversion
The testable implication of the complete risk-sharing hypothesis depends on what is assumed on households' relative risk aversion (RRA) coefficient. We therefore use a hyperbolic absolute risk aversion (HARA) utility function, which includes increasing, constant, and decreasing RRA as special cases, to test this hypothesis. Using household level total non-durable consumption data from Indian vi...
متن کاملCash Flow Risk, Discounting Risk, and the Equity Premium Puzzle
This article investigates the impact of cash flow risk and discounting risk on the aggregate equity premium. Our approach is based on the idea that consumption is hard to measure empirically, so if we substitute out an empirically difficult-to-estimate marginal utility by a pricing kernel of observables, we can evaluate the empirical performance of an equilibrium asset pricing model in a differ...
متن کاملThe Equity Premium a Puzzle*
Restrictions that a class of general equilibrium models place upon the average returns of equity and Treasury bills are found to be strongly violated by the U.S. data in the 1889-1978 period. This result is robust to model specification and measurement problems. We conclude that, most likely, an equilibrium model which is not an Arrow-Debreu economy will be the one that Simultaneously rationali...
