Q 75Q 75
Amy is currently spending her income to maximize her satisfaction. She is renting an apartment for $900 per month as shown in the diagram below (Assume each dollar spent on housing buys 1 unit of housing. H1 represents her $900 per month apartment). a. Suppose that Amy qualifies for a government housing assistance program that will provide her with a $600 per month apartment at no charge. If she accepts the apartment, she cannot augment her expenditure on housing (for example, she cannot add $300 of her income to the $600 per month provided by the government program, and rent the $900 per month apartment), nor can she exchange the apartment for cash or other goods. How does the government program alter Amy's budget line?
b. Suppose that Amy is given $600 in cash instead of the $600 per month apartment. How will this alter Amy's budget line?
c. Is Amy indifferent between the housing assistance program and cash program, or does she prefer one program over the other? Draw an indifference curve to illustrate your answer.

Q 77Q 77
The food stamp program provides low income households with coupons which can be exchanged for some specified dollar value worth of food. Many economists argue that this program is an inefficient means of increasing the well-being of low income families. Proponents of this view argue that an equivalent cash subsidy would bring about a greater increase in the well-being of the low income families receiving aid. Although many economists hold this view, not all policy analysts agree with the advocates of cash payments instead of food stamps. Advocates of the existing program argue that food stamps provide an incentive for low income families to increase the nutritional quality of their diets.
a. Carefully analyze the arguments regarding increases in well-being under cash payments and food stamp programs. Use graphical analysis to present your arguments.
b. Critically evaluate the pros and cons of the food stamp program. Do food stamps ensure that low income families increase their consumption of food?

Now, if the individual's income rises just enough so that his original consumption bundle exactly exhausts his income, will the individual purchase more or less gasoline (this level of income implies the consumer can afford his original consumption bundle)? Is the individual better-off at the higher price level of gasoline with the higher income level or the original price of gas and income?
