Investors who are less risk averse will have what type of utility curves?
A) Flatter.
B) Inverted.
C) Steeper.
the answer is A , I answered C based on the fact that a less risk averse investor would require more return to compensate him/her for taking more risk making the slope of the indifference curve more steeper, what do u think ?
