You have been charged with deciding on optimal fishing policies in order to both encourage growth in the salmon population in the Atlantic and allow fishermen to earn a living. You will need to allow some fishing, but not so much fishing that population counts are depleted for next year. Three proposals are on the table for you to choose from. Option 1: Institute a fishing "window" of 3 weeks wherein fishermen may fish as much as they wish, but after three weeks they must stop. Option 2: Institute a fishing "quota" that will limit the number of fish that any individual fisherman may harvest from the waters.

The quantity in the used car market will be too low relative to the efficient quantity and the price will be too low.

In the aftermath of the financial crisis of 2008, several banking practices came into sharp focus for contributing to the crisis. One of those practices was the issuance of "subprime" mortgages - mortgages made to borrowers who were unlikely to be able to repay in the case of a recession or a decline in housing values. Banks defended their choice by arguing that if the mortgage holders defaulted on the payments, the banks themselves would be the ones taking a loss in profits. In the end, however, the default rate on these loans was so high that the country's entire financial system was at risk of collapse, and taxpayer dollars were used to keep banks solvent. This information indicates that subprime mortgages are _________.
goods with additional social costs

Suppose that a local cable company, the only provider of service, is maximizing profits at a price of $15 per month for local cable service. Assume that some of its customers have quite elastic demands and others have inelastic demands. A price change of $5 per month would cause a change in quantity demanded of 1,000 individual customers. There are 100,000 current individual customers. Businesses are more sensitive to price changes because they often have connections and can easily add or subtract a cable connection. An additional charge of $1 will mean a 100 fewer customers. There are 1,000 business connections in the town. In the above situation, is individual demand is elastic or inelastic? In the above situation, is business demand is elastic or inelastic? As a result of the answers to the previous two questions, the cable company should a.) (increase / decrease) prices for individual customers and b.) (increase / decrease) prices for businesses in order to increase revenues.
inelastic elastic increase decrease
