Some notable recent empirical research on crime

I recently tripped across some recent empirical crime research that seemed worth noting:

From the Journal of Public Economics, "The effect of Medicaid expansion on crime reduction: Evidence from HIFA-waiver expansions," authored by Hefei Wen, Jason Hockenberry and Janet Cummings:

Abstract:  Substance use figures prominently in criminal behavior. As such expanding public insurance and improving access to substance use disorder (SUD) treatment can potentially reduce substance use and reduce crime.  We examine the crime-reduction effect of Medicaid expansions through the Health Insurance Flexibility and Accountability (HIFA) waivers.  We find that HIFA-waiver expansion led to a sizeable reduction in the rates of robbery, aggravated assault and larceny theft. We also show that much of the crime-reduction effect likely occurred through increasing SUD treatment rate and reducing substance use prevalence.  The implied benefit-cost ratio estimate of increased treatment on reducing crime ranges from 1.8 to 3.2.

From the American Journal of Public Health, "Easiness of Legal Access to Concealed Firearm Permits and Homicide Rates in the United States," authored by Michael Siegel, Ziming Xuan, Craig Ross, Sandro Galea, Bindu Kalesan, Eric Fleegler and Kristin Goss:

Abstract

Objectives.  To examine the relation of “shall-issue” laws, in which permits must be issued if requisite criteria are met; “may-issue” laws, which give law enforcement officials wide discretion over whether to issue concealed firearm carry permits or not; and homicide rates.

Methods.  We compared homicide rates in shall-issue and may-issue states and total, firearm, nonfirearm, handgun, and long-gun homicide rates in all 50 states during the 25-year period of 1991 to 2015.  We included year and state fixed effects and numerous state-level factors in the analysis.

Results.  Shall-issue laws were significantly associated with 6.5% higher total homicide rates, 8.6% higher firearm homicide rates, and 10.6% higher handgun homicide rates, but were not significantly associated with long-gun or nonfirearm homicide.

Conclusions.  Shall-issue laws are associated with significantly higher rates of total, firearm-related, and handgun-related homicide.

Silly, lying, false propaganda from notorious, left wing, hate speech propaganda outlets. They are advocating their sicko, misleading agendas. Medical rent seeking is three times as big as lawyer rent seeking, and ten times as deadly. I am not addressing it. It is too big for me.

Also, doctors who feel threatened become mass murderers. See Al Qaeda. See Che Guevara. See the ethnic cleansing of Bosniaks. I do not want to die, just yet.

The reason for the reduction in crime is the reduction in addicts by death, not by treatment.

The reason for must carry rules, is that they are in high violence areas.

Dismissed, pro-criminal, left wing trash. As usual, here.

On another collateral subject, I admire the public accessibility of academic law review contents. They are subsidized by the tax payer, and do not charge for access.

That Commie filth, dirt bag, left wing garbage science outlet, American Journal of Public Health wants $35 to read its stupid article.
