The economic theory of decision making under risk has seen remarkable advances over the 50 years since Pratt’s (1964 …) characterization of risk aversion under expected utility. We review developments in three key areas to which Louis Eeckhoudt has made … significant contributions: (1) increases in risk and risk taking; (2) self-protection and risk aversion; and (3) higher (and lower …

Recently, Caballi and Pomansky (1996) proposed a formal definition of mixed risk aversion and characterized stochastic … dominance in presence of such utility functions. However they did not study comparative mixed risk aversion. In this note we … give a sufficient condition for analytic comparative mixed risk aversion. …
