The graph is a two-panel event-study figure titled "Right-to-Carry Laws and Urban Firearm Crimes."  The left panel plots the estimated change in the firearm violent crime rate in 47 major US cities, relative to the year before right-to-carry (RTC) is adopted.   The right panel plots the estimated change in the firearm robbery rate in 47 major US cities, also relative to the year before right-to-carry is adopted.  The y-axis in both charts range from -20 to 60 percent, and both x-axes range from five years b
When states enact Right-to-Carry (RTC) concealed handgun laws, incidents of violent crimes, robberies, and aggravated assaults involving firearms increase by around a third in major cities as a result of the altered behavior of gun permit holders, career criminals, and the police.

The wealth gap between White and Black Americans is nearly as large today as it was in the 1950s. In Wealth of Two Nations: The US Racial Wealth Gap, 1860–2020 (NBER Working Paper 30101), Ellora Derenoncourt, Chi Hyun Kim, Moritz Kuhn, and Moritz Schularick construct a time series of the ratio of White-to-Black per capita wealth spanning a century and a half. Delving into historical census data, state tax records, and multiple waves of the Survey of Consumer...
National governments that finance their activities by issuing debt must find someone to buy it. The interest rate they must pay to borrow depends on the cost of attracting new buyers, a cost that generally rises along with the outstanding stock of debt. Due in part to government responses to the COVID-19 pandemic, the aggregate government debt-to-GDP ratio is now at its highest level since 2003. Outstanding government debt now exceeds GDP in advanced economies, and is...
Many decisions involve choosing among complex options, and it may be difficult to assess the value of each alternative. In Complexity and Choice (NBER Working Paper 30002), Yuval Salant and Jörg L. Spenkuch use data on 227 million chess moves on an online chess server to study how complexity affects the quality of decision-making. They find that complex optimal options are chosen less frequently than other alternatives that are also optimal but simpler. The...

In keeping with this approach, in most US states all covered workers must pay union dues regardless of union membership. However, the Labor Management Relations Act of 1947, better known as the Taft-Hartley Act, allowed states to introduce “...
