Risk aversion with two risks: A theoretical extension

Journal of Mathematical Economics, 2016, vol. 63, issue C, pages 100-105

Abstract: We identify new conditions ensuring risk aversion in the sense of Arrow–Pratt in a two-argument utility framework in which a financial risk is accompanied by a background risk. Our results generalize the findings of Finkelshtain et al. (1999). We consider a sequence of possible dependence among risks. We also provide an empirical example showing that second-order expectation dependence cannot be ignored in determining risk aversion with two risks.
