The U.S. government spends over $33 billion on its Food Stamp program to provide millions of Americans with the means to purchase food. These stamps are redeemable for food at over 160,000 store locations throughout the nation, and they cannot be sold for cash or used to purchase nonfood items. The average food stamp benefit is about $284 per month. Suppose that, in the absence of food stamps the average consumer must divide $600 in monthly income between food and "all other goods" such that the following budget constraint holds: $600 = $12A + $4F, where A is the quantity of "all other goods" and F is the quantity of food purchased.
Using the vertical axis for "all other goods," draw the consumer's budget line in the absence of the Food Stamp program.
What is the market rate of substitution between food and "all other goods"?
On the same graph, show how the Food Stamp program alters the average consumer's budget line.
Would this consumer benefit from illegally exchanging food for cash? Explain.
Question) Using the vertical axis for "all other goods," draw the consumer's budget line in the absence of the Food Stamp program.
Answer) F (quantity of food purchased) is the horizontal axis. A (quantity of all other goods") is the vertical axis. Sketch
Question) What is the market rate of substitution between food and "all other goods"?
The market rate of substitution is the slope of the line
The slope can be found by using the graph above, and finding the rise divided by the run of the triangle shown. Since the graph slopes downward from left to right, ...
This in-depth solution of over 400 words and 3 graphs explains the market rate of substitution, how the Food Stamp Program alters budget line and if the consumer would benefit from exchanging food for cash.
