10.  Public Choice Theory:
       Economic Concepts Applied to Politics


Government intervention is often recommended as solution to market failure - regulation, taxes, subsidies, persuasion.

Government intervention comes at a cost

administrative costs
enforcement costs
opportunity cost of industry's resources to comply
e.g. manager's time is spent in complying with regulation
price distortion and inefficiency
rent seeking
     e.g. barriers create economic rent for those controlling barriers

Government failure - govt. solution to some problems does not guarantee their improvement.

Public Choice and the Political "Market"

Public choice - application of economic principles to public sector decision making
Assumption of public choice economists -
people are the same, whether they are consumers, employers, and employees,
     or
politicians, bureaucrats, voters, and special interest groups
Their motivation is self interest.
Political Market - participants include:
politicians
voters
special interest groups
bureaucrats
Politician
-moving toward the middle (Exhibit 18-1)
-successful campaigns appeal to the median voter
   opponents are "too liberal" or "too conservative"
   candidates want to be perceived as moderate
   candidates pay close attention to polls
   candidates speak toward ends, not means  
Voters
-benefits of voting - feelings of civic duty, feeling of patriotism, or self interest
-costs of voting - opportunity cost of time to become informed and to vote
-does it matter? - importance of vote
Special interest groups - common interests tie together groups, which hold strong preferences
-better informed and actively participate in political process
-B/C of rent seeking
-congressional districts as special interest groups
-logrolling - exchange of votes to gain support for specific legislation
Bureaucracy
-funding - legislative appropriation
-motive - not profit or cost efficiency
-control - responsible to elected officials
-competition - little, if any
-life span - determined by legislation

Given this, what will be behavior of bureaucrat?
