چکیده

The panel data literature on deterrence and capital punishment contains a wide range of empirical claims despite the use of common data sets for analysis. We interpret the diversity of findings in the literature in terms of differences in statistical model assumptions. Rather than attempt to determine a “best” model from which to draw empirical evidence on deterrence and the death penalty, this paper asks what conclusions about deterrence may be drawn given the presence of model uncertainty, i.e. uncertainty about which statistical assumptions are appropriate. We consider four sources of model uncertainty that capture some of the economically substantive differences that appear across studies. We explore which dimensions of these assumptions are important in generating disparate findings on capital punishment and deterrence from a standard county-level crime data set. Corresponding Author: Durlauf, Department of Economics, University of Wisconsin, Madison WI 53706, [email protected]. We thank Timothy Conley and David Rivers for many helpful insights. Durlauf thanks the University of Wisconsin Graduate School and Vilas Trust for financial support. Hon Ho Kwok and Xiangrong Yu have provided outstanding research assistance.

Assumptions Matter: Model Uncertainty and the Deterrent Effect of Capital Punishment

The effectiveness of capital punishment in deterring homicides has remained unclear despite the fact that the Supreme Court’s moratorium on capital punishment and the subsequent adoption of capital punishment by a subset of states, combined with very different rates of execution across polities, would appear to be an ideal environment for revealing deterrence effects using panel data methods. O...

Does Capital Punishment Deter Murder?

Ethical, philosophical and religious values are central to the continuing controversy over capital punishment. Nevertheless, factual evidence can and should inform policy making. The evidence for capital punishment as an uniquely effective deterrent to murder is especially important, since deterrence is the only major pragmatic argument on the pro-death penalty side.1 The purpose of this paper ...

Model Uncertainty and the Deterrent Effect of Capital Punishment

The reintroduction of capital punishment after the end of the Supreme Court moratorium has permitted researchers to employ state level heterogeneity in the use of capital punishment to study deterrent effects. However, no scholarly consensus exists as to their magnitude. A key reason this has occurred is that the use of alternative models across studies produces differing estimates of the deter...
