6. In the past usury laws were common. A usury law establishes a price ceiling for interest rates, and anyone who charges more is guilty of being a loan shark.
a) Use supply and demand to show what will happen in the market if the legal rate is below the equilibrium rate.
b) The case against usury laws usually assumes that people are rational, that is, they have well-defined goals and act to attain those goals as best they can. Why do usury laws look bad when we make this assumption?
c) Some people reject the assumption that people are rational as economists assume. They argue that some people have self-control problems and are compulsive spenders who ignore the long-run consequences of their actions.

If you view people in this way, why might usury laws look beneficial?
d) What view do you take?
