Racial profiling or racist policing? bounds tests in aggregate data
State-wide reports on police traffic stops and searches summarize very large populations, making them potentially powerful tools for identifying racial bias, particularly when statistics on search outcomes are included. But when the reported statistics conflate searches involving different levels of police discretion, standard tests for racial bias are not applicable. This paper develops a model of police search decisions that allows for non-discretionary searches and derives tests for racial bias in data that mixes different search types. Our tests reject unbiased policing as an explanation ...

Drug prices under the medicare drug discount card program
In early 2004, the U.S. government initiated the Medicare Drug Discount Card Program (MDDCP), which allowed card subscribers to obtain discounts on prescription drugs. Pharmacy-level prices were posted on the program website weekly with the hope or promoting competition among card sponsors by facilitating consumer access to prices. A large panel of pharmacy-level price data collected from this website indicates that price dispersion across cards persisted throughout the program. Prices declined initially when consumers were choosing cards, but rose later when subscribers were restricted to ...
Layoffs during the COVID-19 Pandemic: Four Findings from WARN Act Data
With economic conditions changing so rapidly during the COVID-19 pandemic, the standard layoff indicators that policymakers and analysts use are falling short. These indicators are either not released frequently enough, or they lack geographic or industry information. Some indicators, such as initial unemployment insurance claims, may be less accurate under the current extreme conditions because of processing delays, duplicate claims, and fraud.2

Regional aggregation in forecasting: an application to the Federal Reserve’s Eighth District
Hernndez-Murillo and Owyang (2006) showed that accounting for spatial correlations in regional data can improve forecasts of national employment. This paper considers whether the predictive advantage of disaggregate models remains when forecasting subnational data. The authors conduct horse races among several forecasting models in which the objective is to forecast regional- or state-level employment. For some models, the objective is to forecast using the sum of further disaggregated employment (i.e., forecasts of metropolitan statistical area [MSA]-level data are summed to yield ...

The effect of neighborhood contagion on mortgage selection
In this paper we conduct an empirical investigation of how neighborhood mortgage adoption contagion affects mortgage product choice, with an emphasis on Hispanic borrowers. We use loan-level mortgage data for metropolitan areas in California and Florida during 2004 and 2005, the peak years of the subprime mortgage boom. We identify an important and statistically significant effect of contagion on consumer choice of hybrid mortgage products that were popular during this period, especially for Hispanic borrowers.

Tax competition and tax harmonization with evasion
We examine a two-jurisdiction tax competition environment where local governments can only imperfectly monitor where agents pay taxes and risk-averse individuals my choose to cross borders to pay lower taxes in a neighboring location. ; In the game between local authorities, when communities differ in size, in equilibrium the smaller community sets lower taxes and attracts agents from the larger jurisdiction. With identical communities, tax rates must be equal. Whenever the smaller community benefits from tax harmonization, the larger one will also. ; If the high-tax community chooses a ...

Clustered housing cycles
Using a panel of U.S. city-level building permits data, we estimate a Markov-switching model of housing cycles that allows cities to systematically deviate from the national housing cycle. These deviations occur for clusters of cities that experience simultaneous housing contractions. We find that cities do not form housing regions in the traditional geographic sense. Instead, similarities in factors affecting the demand for housing (such as population growth or availability of credit) appear to be more important determinants of cyclical co-movements than similarities in factors affecting the ...
