Pulling Leviathan's Teeth The Political Economy of Death Penalty Abolition

Abstract

It is not immediately apparent why a state would willingly abolish the death penalty and thereby lose a powerful political instrument. The fact that some states abolish capital punishment while others retain it has thus far been explained by systematic differences in the values of politicians or citizens. An explanation of different behavior based on different preferences for such behavior is, however, largely tautological and not of much use to social science. This article proposes and empirically tests a political economy model in which rational politicians are more likely to abolish the death penalty when it is of no political use to them and if the process of abolition serves as a self-commitment in periods of transition. The results of estimating stratified Cox regression models show that the death penalty tends to be abolished particularly during periods of democratization and transitions to peace, but also that independence of the judiciary can encourage abolition. In contrast, military dictatorships are significantly more likely to retain capital punishment, as are countries with a common law legal system and those that are strongly politically influenced by Islam. These findings support the view that the abolition of capital punishment is at least partly motivated by rational political considerations.
