Predict how each of the following events will raise or lower the equilibrium wage and quantity of oil workers in Texas. In each case, sketch a demand and supply diagram to illustrate your answer.

1. The price of oil rises.
2. New oil-drilling equipment is invented that is cheap and requires few workers to run.
3. Several major companies that do not drill oil open factories in Texas, offering many well-paid jobs outside the oil industry.
4. Government imposes costly new regulations to make oil-drilling a safer job.

1. The number of people at the most common ages for home-buying increases.
2. People gain confidence that the economy is growing and that their jobs are secure.
3. Banks that have made home loans find that a larger number of people than they expected are not repaying those loans.

Table 4.6 shows the amount of savings and borrowing in a market for loans to purchase homes, measured in millions of dollars, at various interest rates. What is the equilibrium interest rate and quantity in the capital financial market? How can you tell? Now, imagine that because of a shift in the perceptions of foreign investors, the supply curve shifts so that there will be \$10 million less supplied at every interest rate. Calculate the new equilibrium interest rate and quantity, and explain why the direction of the interest rate shift makes intuitive sense.

Interest Rate Qs Qd
5% 130 170
6% 135 150
7% 140 140
8% 145 135
9% 150 125
10% 155 110

Imagine that to preserve the traditional way of life in small fishing villages, a government decides to impose a price floor that will guarantee all fishermen a certain price for their catch.

1. Using the demand and supply framework, predict the effects on the price, quantity demanded, and quantity supplied.
2. With the enactment of this price floor for fish, what are some of the likely unintended consequences in the market?
3. Suggest some policies other than the price floor to make it possible for small fishing villages to continue.
