In their paper "Measuring Privatization: Comparing Five Indicators of the Disposition of State-Owned Enterprises in Advanced Democracies", published in Volume 21:4 of the Journal of Comparative Policy Analysis, Son and Zohlnhofer examine the use of indicators to determine privatization.
In the scientific literature, numerous such indicators are circulating, most of which are treated as equivalents. However, little attention is paid to whether they actually match each other closely. In their paper, Son and Zohlnhofer state that the correlations between these indicators are alarmingly low. As a consequence, it has been shown that the results of statistical analyses can differ significantly depending on which privatisation indicator is used. Son and Zohlnhofer therefore suggest that the different indicators should not be considered as equivalents but as measurements of different aspects of privatisation.
The jury explained its decision to award the prize to Son and Zohlnhofer with the following words:
"'Measuring Privatization' by Son and Zohlnhöfer takes comparative policy analysis seriously and advances the field by shedding light on the multiple dimensions of different dependent variables/indicators that often have been seen as substitutes for each other. The authors highlight the importance of choosing the right indicators to explain phenomena that analysts seek to understand. They illustrate why scholars using large-N data sometimes end up with inconclusive or mixed results when they ignore this fundamental issue. More importantly, this study of state-owned enterprises has implications for other sectors and comparative approaches to important policy issues. The focus on indicators is widely used in comparative policy analysis, and this article contributes to the policy literature on privatization and to the development of methods in the broader field of comparative policy studies."
