In 1997, John Lott and David Mustard published an important paper in which they found that right‐to‐carry concealed weapons laws reduce violent crime. Although Lott and Mustard appear to do all possible variations of the analysis, a closer reading reveals that the study might suffer from several possibly important errors. I reestimate the model and check for incorrect functional form, omitted variables, and possible second‐order bias in the t‐ratios. Lott and Mustard's basic conclusions are… Expand
Using Placebo Laws to Test "More Guns, Less Crime"
Abstract We reexamine Mustard and Lott’s controversial study on the effect of “shall-issue” gun laws on crime using an empirical standard error function randomly generated from “placebo” laws. WeExpand
Statistical Variability and the Deterrent Effect of the Death Penalty
In a recent paper Donohue and Wolfers (DW specifically, that the estimated standard errors on the subset of his regressions that suggest a deterrent effect are downward biased due to autocorrelation.Expand
Privately Produced General Deterrence*
In this study, we use county data on private security establishments and employment for 1977–92 to test two hypotheses. First, we test whether private security deters crime. Second, we test whetherExpand
RTC Laws Increase Violent Crime: Moody and Marvell Have Missed the Target
An NBER working paper by Donohue, Aneja, and Weber (DAW) estimates the impact of right-to-carry (RTC) laws and finds using data from 1979–2014 that RTC laws lead to significant increases in violentExpand
Regression to the Mean, Murder Rates, and Shall-Issue Laws
The relationship between state murder rates and the liberalization of conditions under which a citizen can obtain a permit to carry a concealed weapon (shall-issue laws) is controversial andExpand
Do Right-to-Carry Concealed Weapons Laws Still Reduce Crime?
A review of the literature studying the effect of right-to-carry laws shows that the weight of evidence indicates that such laws reduced violent crime. However, more recent studies, using more recentExpand
Citizen, defend thyself: an individual‐level analysis of concealed weapon permit holders
Research on right‐to‐carry laws and subsequent crime reduction has relied heavily on the use of econometric models relying on aggregate‐level data. We examine the underlying individual‐levelExpand
Trust But Verify: Lessons for the Empirical Evaluation of Law and Policy
In a recent article, Aneja, Donohue and Zhang claim that they are unable to replicate the regressions published by the National Research Council in Chapter 6 of Firearms and Violence. They concludeExpand
The Decision to Carry
Despite persistent debate on the role of concealed-carry legislation, decisions to legally carry concealed handguns are not well understood. Using detailed data on concealed-carry permitExpand
Gun Prevalence, Homicide Rates and Causality: A GMM Approach to Endogeneity Bias
The positive correlation between gun prevalence and homicide rates has been widely documented. But does this correlation reflect a causal relationship? This study seeks to answer the question ofExpand

Crime, Deterrence, and Right‐to‐Carry Concealed Handguns
Using cross‐sectional time‐series data for U.S. counties from 1977 to 1992, we find that allowing citizens to carry concealed weapons deters violent crimes, without increasing accidental deaths. IfExpand

Private expenditures on crime reduction have potentially important externalities. Observable measures such as barbed-wire fences and deadbolt locks may shift crime to those who are unprotected,Expand
More Guns, Less Crime: Understanding Crime and Gun-Control Laws
On its initial publication in 1998, John R. Lott, Jr.'s "More Guns, Less Crime" drew both lavish praise and heated criticism. More than a decade later, it continues to play a key role in ongoingExpand

Several procedures are proposed for testing the specification of an econometric model when one or more models purport to explain the same phenomenon. These procedures are closely related, althoughExpand
Crime and Social Interactions
The high degree of variance of crime rates across space (and across time) is one of the oldest puzzles in the social sciences (see Quetelet (1835)). Our empirical work strongly suggests that thisExpand

Theoritical considerations suggest that spillover forces equalize wages for similar jobs. Thus, it is expected that firm wages are cointegrated with the corresponding wage rates on an industrialExpand
