This special issue of the Journal of Quantitative Criminology is committed to the publi-
cation of papers commissioned by the National Research Council's Committee on
Deterrence and the Death Penalty.
In 1976, the Supreme Court decision Gregg v. Georgia, 428 US 153 ended the four-year
moratorium on executions that resulted from its 1972 decision in Furman v. Georgia, 408
US 238. In the immediate aftermath of Gregg, an earlier report of the National Research
Council by Blumstein, Cohen, and Nagin (1978) reviewed the evidence relating to the
deterrent effect of the death penalty that had been gathered through the mid-1970s. That
review was highly critical of the earlier research and concluded (1978:9) that available
studies provide no useful evidence on the deterrent effect of capital punishment.
During the thirty-five years since Gregg, and particularly in the past decade, many
additional studies have renewed the attempt to estimate the effect of capital punishment on
homicide rates. Most researchers have used post-Gregg data from the US to examine the
statistical association between homicide rates and the legal status and/or the actual
implementation of the death penalty. The studies have reached widely varying, even
contradictory, conclusions. Some studies conclude that executions save large numbers of
lives whereas others conclude that executions actually increase homicides and still others
conclude that executions have no effect on homicide. Commentary on the scientific
validity of the findings has sometimes been acrimonious.
The Committee on Deterrence and the Death Penalty was convened against this
backdrop of conflicting claims about the effect of capital punishment on homicide rates.
The Committee report which is a publication of the National Academy Press (NRC,
forthcoming), addressed three main questions laid out in its charge:
1. Does the available evidence provide a reasonable basis for drawing conclusions about
the magnitude of capital punishment's effect on homicide rates?
2. Are there differences among the extant analyses that provide a basis for resolving the
differences in findings? Are the differences in findings due to inherent limitations in
the data? Are there existing statistical methods and/or theoretical perspectives that
