Suppose that the equilibrium rent for a two-bedroom apartment in downtown Chicago
is $900 per month. The city council decides to place a price ceiling on apartments and
will not allow landlords to charge more than $700 per month. Draw this situation using

The Securities and Exchange Commission of the U.S. government requires that mutual
fund companies publish a long and detailed prospectus which covers an array of areas
including the cost of owning the fund, the types of stocks the fund invests in, the
management fee, administrative fees and an assessment of the type of risk that holding
the fund represents. This is clearly designed with the intent of mitigating the imperfect
information problem. However, can you think of any reason why the value of these
documents is likely to be quite marginal?
