  1. Political Economics & Public Choice Review, Comparison and Application

  2. Part I Review of the Public Choice Theory

  3. Origin • Mid 20th Century • Has a close relationship with the background of that period • The Great Depression in 1930s • Welfare Economics and Keynes Economics • Economists focused on the market at that time • The requirement of explaining the public choice

  4. The Triangulum Headshot Not Available Duncan Black James M. Buchanan Kenneth J. Arrow

  5. Duncan Black (1908-1991) • Econ Prof. of North Wales University • “Father of the Public Choice Theory” • In his “The theory of committees and election“ (1958), the notion of committee decision was brought out. • Additionally, he delved into the research of the voting progress and create the basic framework of the election theory.

  6. James M. Buchanan(1919 - ) • The most influential scholar in P.C.T • Got 1986’s Nobel Prize for his contribution of Public Choice Theory • “The Calculus of Consent: Logical Foundations of Constitutional Democracy”(1962) • 2 gradations: choice under the rules and the choice of rules • Ordinary Politics and Constitutional Politics • Center for Study of Public Choice

  7. The Center for Study of Public Choice George Mason University

  8. Kenneth J. Arrow(1921- ) • Econ Prof. of Stanford • Got 1972’s Noble Prize for his contribution to the Public Choice • “Social Choice and Individual Values”(1951) • Arrow Impossibility Theorem • Marked the formation of Public Choice Theory

  9. Public Choice Under the Direct Democracy • At the very beginning, the study of public choice focused on the choice under the direct democracy. • Arrow and Black

  10. Arrow’s study • Public choice is a collection of individuals’ choices (Arrow, 1951) • The essence of this theory is the mapping between individual and public • f:(R1, R2…..RN) R • Arrow impossibility theorem • Development: • 1. New ways of proving • 2. By changing of assumption, new impossibility theorem came out (Sen, 1970)

  11. Black’s Study • Voting rules under direct democracy • Median Voter Theorem (Black, 1958): if voter policy preferences can be represented along one dimension, if a voter always votes for the politician that commits to a policy position closest to their own preference, and if there are only two politicians, then if the politicians want to maximize their number of votes they should both commit to the policy position preferred by the median voter. • One-Dimension to Multi-Dimension (Davis Otto A, 1972 )

  12. Public Choice Under the Representative Democracy • Based on the study of public choice under the direct democracy • Nowadays, representative democracy is prevalent all over the modern society • 4 components: • Origin of the Government • Motivation of the government’s expenditure • Rent Seeking • Free Rider Theory

  13. Origin of the government • Anthony Downs • “An Economic Theory of Democracy”(1957) • “Instead of trying to win the election for making policies, parties make policies to win the election.” • Space theory for two parties • Space theory of voting for more than 3 parties (Tullock,1976)

  14. Motivation of the government’s expenditure • Based on the assumption of “economic man ” • The government try to achieve its goal instead of the goal of the public (Downs, 1957) • “Maximum Budget” and Niskanen Model (Niskanen, 1971) • Expansion (Breton, Albert and Ronald Wintrobe, 1971) • Criticism and new models (Downs, 1967)

  15. Rent Seeking • Tullock, Gorden. The Welfare Cost of Tariffs, Monopolies and Theft , 1967 • The term “rent seeking” make its debut by Krueger(1974) • “Rent exists everywhere, thus the behavior of rent seeking is inevitable.” (Mueller, 1989) • “The best way to eliminate the rent seeking is the reform of the system. ” (Mueller, 1989) • Bucharnan, Toward a Theory of Rent-Seeking Society, 1987

  16. Free Rider Theory • Olson, Mancur. The logical of Collaborative Action: Public Goods and the Theory of Groups, 1965 • “In a big group, the “economic man” is not willing to make effort to achieve the goal of the group.” (Olson, 1965) • “Only if the incentive exists, big groups do worse than the small groups in collective behavior.” (Olson, 1965) • Similar with the “Prisoners’ Dilemma”.

  17. Constitutional Political Economy • An important field of Public Choice Theory • Buchanan, Tullock. The Calculus of Consent: Logical Foundations of Constitutional Democracy, 1962 • Choice Under the Rules and the Choice of the Rules. (Buchanan, Tullock, 1962) • Constitution Utilitarian Contract • “The choice of Constitution is the choice of Social Rules. The constitution should be agreed by the public. The functions of constitution are protect the popularities’ legal rights and limit the power of the government” (Brennan, Buchanan, 1985)

  18. Constitutional Political Economy • Mueller(1971, 1973, 1996) delved into the Constitutional Democracy • Analysis in Game Theory (Riley, 2001) • The Journal: Constitutional Political Economy

  19. Part II Political Economics versus Public Choice

  20. General Comparison • 3 basic differences : • Point of reference • The importance they assign to individual liberty • Attitude to modeling techniques

  21. Different point of reference • “Choice versus Conflict” • P.E starts its analysis within the framework of existing representative democracy and focuses on the coercive character of the state. (Persson and Tabellini, 2000) • P.C starts at the individual level. The yardstick for the general legitimacy of the state and its decisions is there fore the individual willingness of all citizens to join a state and accept its decisions. This is why public choice puts voluntary exchange at its core. (Buchanan, 1954)

  22. The Importance of Individual Liberty • “Efficiency versus Liberty” • Based on different points of reference, the two approaches derive different criteria to evaluate political decisions and political institutions. • P.E assigns central importance to efficiency considerations of political decisions within the representative democracy (Ursprung 2003) • P.C assigns the greatest importance to the value of individual liberty and its promotion as a criterion to evaluate political decisions and institutions. (Buchanan and Roger, 1998 )

  23. Attitude to modeling techniques • “Methodological Determination versus Methodological Openness” • P.E studies “some of the classic problems in public choice”, adopting a general-equilibrium approach with explicit micro political foundations. • P.C always reject the idea that the discipline is defined by the analytical tools or techniques it uses and focused instead on the questions it wants to answer.

  24. Part III Application

  25. Introduction • How can we evaluate the “current score” of the competition between these two approaches? • I propose to compare the results of the two with respect to their common scientific goal: to derive normative implications for institutional improvement

  26. Institutional Improvements • P.E contributed very successfully and derived important new suggestions for institutional improvements. • However the success may have nourished the fallacious opinion that the only barrier for taking over P.C is the technical problem solving. • Unfortunately, this belief has blurred the perspective of the P.E research and led to unconvincing results. • Additionally, the newer contribution of P.E have been unable to provide any meaningful advice for institutional innovations.

  27. Why? • The causal factors for the decline of P.E research are as follows: • Its inability to define a relevant point of reference outside the given institutional setting • Its concentration on the coercive character of the state • Its preference for efficiency considerations over concerns for individual liberty • Nevertheless, P.C, with Wicksell as its point of reference and individual choice and liberty as its main criteria, do better in deriving for institutional improvements

  28. Conclusion • Hence, measured by their common scientific goal to derive normative implications for institutional improvements, we still see an edge for public choice in the economic analysis of politics • Nonetheless, there is an ongoing competition that can only benefit both approaches of political economy. Solely looking in the “queen’s mirror” will bring neither public choice nor political economics forward
