Effects of background risks on cautiousness with an application to a portfolio choice problem
نویسندگان
چکیده
We provide a necessary and a sufficient condition on an individual’s expected utility function under which any zero-mean idiosyncratic risk increases cautiousness (the derivative of the reciprocal of the absolute risk aversion), which is the key determinant for this individual’s demand for options and portfolio insurance.
