1. In a single risky security setting, define the wealth elasticity of demand for the risky security by: da * w n dw a* a. Show that increasing, constant and decreasing relative risk aversions imply that n is respectively less than, equal to, and greater than 1. b. Relate n to the behavior of the proportion of wealth invested in the risky security as wealth changes. 1.
