Prove that that contract curve will be a straight line if the utility function for both consumers is U=3x²_iy_i

Expert Solution

The pareto-optimal allocations would be where . For the consumer A, we have the utility as , and the marginal rate of substitution would be as or or or or or . It can be also found as , which would yield the same result.

For consumer B too, we have the same utility as , and the marginal rate of substitution would be as or or or or or .

The pareto-optimal allocation in this case would hence be where or or . The feasibility conditions are and or and , where and are the (given) endowments of A and B.

Putting this to the pareto-optimal condition, we have or or or or , which is the contract curve, and is an equation of straight line through the origin.

A basic feature of the utility function (demand curve) is the law of diminishing marginal utility. That is, as a person consumes an item or a product, the satisfaction or utility that they derive from the product wanes as they consume more and more of that product. In other words, the price a person is willing to pay (or the demand) for that product decreases with consumption. However, our demand for some environmental goods (e.g., clean air/water) does not wane...

5. In the gizmo market, the supply curve is the typical upward-sloping straight line, and the demand curve is the typical downward-sloping straight line. The equilibrium quantity in the gizmo market is 50,000 gizmos per month when there is no tax. Then a tax of $5 per gizmo is imposed. As a result, the government is able to raise $231,200 per month in tax revenue. We can conclude that the equilibrium quantity of gizmos has decreased by _______ gizmos per...
