1 . Consider a client with cuasi-linear preferences showed by the energy function:

U  c, g   c  three or more g in which c is a private very good and g is a genuine public very good. The price of the private great is $12 per unit and the value of the public good $1. Assume the customer has $1, 000 to spend. Calculate the utility maximizing quantities of c* and g*. Response:

Max U  c, g   c  several g

Our company is interested in an inside solution with c, g  0, so we all assume 0  zero, 1  0, 2  0. We rewrite (1. 1) as

To obtain the optimum value of c, we replace g in the finances constraint.

2 . Now imagine the consumer features $1, 800 to spend. How will the enhancements made on income impact the optimal quantities of c and g. Why?

Answer:

g*  8

c*  149. 33

The brand new optimal principles show us that with a cuasi-linear utility function all the salary affect will be absorbed by the private very good.

3. At this point the power function is usually U  c, g   5c  g as well as the consumer features $1, 500 to spend. Find the principles of c and g that improve his electricity.

Answer:
