Due to federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use the discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...

This paper develops a generalized hedonic model in which an exogenous shock to a single product attribute can affect other attributes, the markets for the product's complements and substitutes, and aggregate quantity produced. These factors are shown to be empirically relevant and to cause bias...

This paper uses a recent increase in Wisconsin’s tobacco tax as a natural experiment to measure the economic incidence of tobacco taxation, using micro-level data on cigarette prices from retail locations in Wisconsin and states that share its border. We find that Wisconsin’s $1 tobacco tax...

This study uses for official use only data on US military operations to evaluate the large-scale Army policies to replace relatively light Type 1 tactical wheeled vehicles (TWVs) with more heavily protected Type 2 variants and later to replace Type 2s with more heavily protected Type 3s. We find...

This article estimates the effect of offering an expedited citizenship application process to noncitizens for joining the US military. Executive Order (EO) 13269, enacted in July of 2002, allowed noncitizens to apply for US citizenship immediately upon joining the military, effectively reducing...

This comment discusses the pros and cons of the methodology and data used in our previous study on the cost-effectiveness of armor on Tactical Wheeled Vehicles (TWVs), and responds to recent critiques by Franz Gayl. In our previous article, we evaluated the large-scale Army policies to replace...

Our research uses data from multiple archival sources to examine substitution among armored (tank-intensive), infantry (troop-intensive), and airborne (also troop-intensive) military units, as well as mid-war reorganizations of each type, to estimate the marginal cost of reducing U.S. fatalities...
