In light of a recent mass shooting in Nova Scotia, the Prime Minister of Canada intends to ban a lot of firearms. I have seen both sides of this debate, notably whether or not gun control is an effective strategy to reducing violent crime. Gun control itself is a supply-reduction policy whereas loosening gun control coupled with more severe penalties for offenders who use guns is a demand-reduction policy. Both sides of this have valid arguments, though, which one is more effective? This is an economics policy question.
I have not seen very much attention given to this topic from economics. Is there a well defined economics literature surrounding gun control and its efficacy (does it work)? Maybe econometric studies examining gun control laws imposed in certain states as natural experiments?
I am not simply asking "Does gun control work" as this would attract opinion-based answers. I am looking for studies that have examined the effects to better inform myself on the subject, on which I have not formed an opinion.
