SCENARIO 1: Consider the interactions between the markets for beer and cola drinks.

consumption and that labor is mobile between the two industries.

negative externality.

production possibility frontier?

politicians will recognize this when pressed. However, typically liberals will tout the

Suppose that you and two friends have an opportunity to purchase a pizza restaurant.
Each of you would put up $75,000. The revenue from the restaurant is expected to
remain $200,000 per year for the next several years. The costs (not including the
opportunity costs of your investment) of operating the restaurant are expected to remain
steady at $185,000 for the next several years. The current market rate of interest is 7

The rash of hurricanes that pelted the Gulf Coast in 2005 resulted in a large decline in
gasoline production as many offshore rigs were shut down and many refineries were
taken off line while waiting out the hurricane. The decrease in supplies of gasoline led
to a run up in prices. Many voters clamored for relief by calling on their congressman
and senators to enact temporary price controls. Analyze the impact on the gasoline
market that would have transpired had politicians actually headed the calls by voters to
impose price controls on gasoline.

involves providing $100 in cash. Plan B involves providing $100 in food coupons that
can only be spent on food.

under Plan A? What is likely to happen to his consumption of both food and "all other
goods" if they are both normal goods?
