1.    High yield ("junk") bonds were sometimes used to finance corporate takeovers during the 1980s.  In class, I related the received wisdom that there was a relationship between the emergence of junk bonds and the fact that many large firms were subject to takeover bids.  Junk bonds enabled small firms to obtain financing to take over much larger firms.  Taking over such large firms is risky, and so-called investment grade bonds promised too low a return to finance such an enterprise.

This explanation, however, is incomplete.  It does not explain why takeovers tended to be financed with junk bonds rather than through new equity issues.  Firms engaged in takeovers could in principle do so by selling new shares.


2.     A survey of cab drivers in LA reports the following phenomena.  On average, drivers who own their own cabs pay their company 25% of the fares they receive.   In contrast, drivers who drive cabs owned by their company are pay their company 75% of the fares they receive.  The survey also reports that base wages tend to be higher for companies who drive company cabs than those who drive their own.

 In LA, customers tend to "hail" cabs by calling in to a cab company and requesting service.  In New York, they tend to hail them by standing on street corners and indicating that they need a cab.

3.     Define "complete contract."


4.     Describe conditions whereby bargaining alone will necessarily lead to the implementation of efficient arrangements.
