. Explain the interpretation of a utility function and why such a function should be
increasing.
is said that the utility function of a decision maker is given by
Ua(x) = 2ax – x², r € R
for some a > 0.For which lotteries with random outcomes X is the above function a utility
function? Explain your answer and give an example of a lottery or specify a distibution
of the random variable X for which the function mentioned in relation 2 is not a utility
function.
3.
Consider a decision maker with initial wealth 0 and this decision maker needs
to play a lottery L having a random outcome X bounded above by a > 0. This means
P(X < a) = 1. Is this decision maker risk averse or risk seeking for this particular lottery?
Explain your answer and give the definion of riskaverse and risk seeking!
4.
Let a > 0 be given and L a lotery with random outcome X having cumulative
distribution function
if r < 0
F(x) = { a-lx if 0 < x < a
if r > a
and assume that the utility function of the decision maker having initial wealth w = 0 is
given by the function uq listed in relation 2. Compute the expected utility of this lottery and
the certainty equivalence of this lottery.
