Authoritarian regime types revisited: updated data in comparative perspective

Abstract

This article introduces a modified and updated version of the authoritarian regime type dataset first introduced by Hadenius and Teorell. The basic logic and merits of this dataset is presented, previously published criticism of the index is addressed and practical advice for potential users is provided. The dataset is also compared theoretically and empirically with the datasets provided by Cheibub et al., and Geddes et al. It is argued that the choice of dataset is likely to have a substantial effect on the results of empirical research. The different datasets all have their respective strengths and weaknesses. However, our typology of authoritarianism distinguishes itself from the alternative categorisations in that it recognises the heterogeneous character of electoral regimes and provides a category corresponding to the theoretically interesting class of ‘electoral authoritarian’ regimes.
