Indices of Power IOP 2.0
IOP calculates various voting power indices for simple voting games in uni- and multicameral institutions with actors having weighted and/or unweighted votes including Shapley-Shubik index, inclusiveness index, non-normalized and normalized Banzhaf index, public good index, member bargaining power index, Deegan-Packel index, Coleman’s decision probability index.
The link http://www.tbraeuninger.de/IOP.html is not working at the moment. Sorry. But here is the packed file IOP 2.0 R5 and a short manual. If that’s not working, here is the x64 version IOPv205-x64.exe of the executable file.
LIMED (version 1.0)
Limed calculates limiting “median hyperplanes” for spatial voting games in two or three policy dimensions. Limed can handle a large range of voting rules such as weighted voting in unicameral systems with actors having multiple voting weights (e.g., European Union Council of Ministers) or (un-)weighted voting in bi- or multicameral system (e.g., US Congress).
Limed requires the commercial program Gauss (Aptech System, Inc.) and runs on any hardware and operating system that runs Gauss. To download a zipped version of Limed, a user guide and some data examples, click here.
LIMED was used to compare alternative uni- and multicameral decision-making rules for the International Seabed Authority using a three-dimensional spatial representation of states’ preferences; see Thomas Bräuninger (2003) When Simple Voting Doesn’t Work. Multicameral Systems for the Representation and Aggregation of Interests in International Organisations. British Journal of Poltical Science 33(4): 681-703.
Mineps (version 1.0)
Mineps analyses spatial voting games with actors having Euclidean preferences in a two dimensional space. It calculates the yolk (yolk center and yolk radius) and the minimal epsilon so that the epsilon-core is not empty. The epsilon-core is a generalization of the conventional core where individuals do not regard a proposal as attractive unless it is a finite (epsilon) distance closer to their ideal point than the status quo (cf. Shapley/Shubik 1966). The minimal epsilon equals the minimal finagle radius (Wuffle et al. 1989) of a two candidate electoral competition (Bräuninger 2007). Mineps has four options:
1. calculate the yolk for a given set of ideal points
2. calculate the yolk and the minimal epsilon for a given set of ideal points
3. run a number of experiments: draw ideal points from a uniform/normal distribution and do 1.
4. run a number of experiments: draw ideal points from a uniform/normal distribution and do 2.
Mineps was used to show that both the size of the yolk and the ratio between yolk radius and minimal epsilon is decreasing as the size of a committee is increasing (Thomas Bräuninger (2007) ‘Stability in Spatial Voting Games with Restricted Preference Maximizing’, Journal of Theoretical Politics 19(2): 173-91).
