Datasets / Solution Concepts


Solution concepts I created:

The Strongly Stable Core. For greater detail, see  HeeMin Kim.1995. "The Strongly Stable Core in Weighted Voting Games." Public Choice 84:77-90 

Data sets I created (with Richard c. Fording)

Over the years, Richard Fording (University of Alabama) and I created several measures of ideology based on the Comparative Manifestos Project data.*  They include:

 [1] The Kim-Fording Measure of Party Ideology                                                                                      [2] The Kim-Fording Measure of Voter Ideology                                                                                                 [3]  The Kim-Fording Measure of Parliament Ideology I  (A Weighted-Mean Version).                          [4]  The Kim-Fording Measure of Parliament Ideology II (A Median Version).                                        [5]  The Kim-Fording Measure of Government Ideology.                                                                       [6]  The Kim-Fording Measure of Democratic Performance (Congruence).

Here the data are available for 25 Western democracies for 1945-2013.

  • Data sets I created (with Marius Radean):

    The Measures of the Median Voter Ideology, the Median Constituency Ideology (the supporters of the current government), the Government Ideology based on Citizen Survey, the Government Ideology based on Expert Survey, and Congruence/Distortion Measures (the distance between any pair above).  They are based on the Comparative Study of Electoral Systems (CSES) Data and Created with Marius Radean, a Lecturer at the University of Essex.  We will continue to update these data as the CSES becomes updated.
