Teaching the coase theorem: Are we getting it right?

The authors examine current textbook representations of Coase's analysis of negative externalities [Coase, 1960]. Standard treatments identify Coase's ideas with Stigler's Coase Theorem: a zero transaction cost world in which efficient solutions emerge automatically, regardless of legal rules and the initial allocation of rights. Yet Coase's seminal paper breaks from this mode of analysis. The authors use this intellectual history to distinguish two approaches to negative externalities: blackboard (Pigou, Stigler, Samuelson) and Coasean. They survey 45 microeconomics textbooks and find that 80 percent misrepresent Coase's arguments. They argue that a Coasean approach increases students' critical thinking skills by challenging them to move beyond simple laissez faire or interventionist solutions.     

The market for private student loans: an analysis of credit union exposure,risk, and returns

Beginning in 2011, credit unions in the United States have been required to report in their quarterly call reports their holdings of private student loans. Since this time, private student loans have been the fastest growing loan product among credit unions. The empirical results here indicate credit unions respond to external market forces and internal exposure to interest rate risk in their decision to hold private student loans. The effect of which, to date, has led to lower returns on their assets and no effect on overall risk. Credit unions looking to diversify their loan portfolio should do so with caution. Private student loans being in deferral reduce both delinquency and charge-off rates, which will rise over time with their seasoning and as interest rates rise.
