a What is my expected utility?
b How much insurance should I buy to be fully insured?
c What is a fair insurance premium?
d What is my utility if I buy full insurance at the fair insurance price?
2. A productionfunction is given by f(xa1xb2xc3), where a + b + c > 1.
a Proof that the function is showing increasing returns to scale.
3. Look at the costfunction c(y) = 3y2 + 22
a order AC(y), AVC(y) and MC(y) and illustrate the in a ?gure.
b What output minimize AC(y)?
c which output gives that AC(y)=MC(y)
4 Look at a competetive market with many companies who all have identical costfunctions given by c(y) = 0.5y2 + 1 for y > 0 and c(0) = 0.
It seems like we have a demand in the market at D(p) = 23 - p
a Order the suplycurve Si(p) for each company
b With n companies in the market, order the whole supplycurveS(p) for the industry.
c What is the lowest cost we can have to sell products in this market?
d How much will each company produce at this price?
e How many companies will exist in this market at this price?
