y
f(x)
x
2)
Graphically show both the long-run and short-run profit function as a function of output price
and then as a function of an input price.
3)
For the utility function, u = ln (x), compute Pratt’s risk coefficient and determine whether this
utility function exhibits increasing or decreasing aversion to risk.
4)
In the fall of 1998, milk prices in New York are very high and feed prices are low.
Most

What would
you suggest to dairy farmers for whom you have cost function information.
5)
A technological change occurs which shifts the production function up at all input levels but
