Abstract We exploit daylight saving time (DST) as an exogenous shock to daylight, using both the discontinuous nature of the policy and the 2007 extension of DST, to consider the impact of light on criminal activity. Regression discontinuity estimates show a 7% decrease in robberies following the shift to DST. As expected, effects are largest during the hours directly affected by the shift in daylight. We discuss our findings within the context of criminal decision making and labor supply, and… 
Ambient Lighting and Arrests: Evidence from a Natural Experiment
Objectives This study assesses whether changes in outdoor lighting affect the likelihood that a crime results in an arrest. Methods This study uses crime data from the FBI’s National Incident-Based
How Dark Is Dark? Bright Lights, Big City, Racial Profiling
Abstract Grogger and Ridgeway (2006) use the daylight saving time shift to develop a police racial profiling test that is based on differences in driver race visibility and (hence) the race
Aggression and sleep: a daylight saving time natural experiment on the effect of mild sleep loss and gain on assaults
ObjectivesThe purpose of this study was to test the effect of a mild, short-term sleep loss/gain on assault rates.MethodsUsing National Incidence Based Reporting System data and city-reported data
Air Pollution and Criminal Activity: Microgeographic Evidence from Chicago

The Effect of Moonlight on Outdoor Nighttime Crime
The use of outdoor lighting, particularly through street lights, is a common tool for policy makers attempting to reduce crime. Research on the effect of lights on crime, however, are limited as
Stress on the Sidewalk: Mental health costs of close proximity crime
I apply novel, extremely micro-level datasets to provide new evidence on crime's impact on mental health. I find that each reported violent and sexual crime significantly increases the stress levels
Punishment and Crime: The Impact of Felony Conviction on Criminal Activity
This paper uses increases in felony larceny thresholds as a negative shock to felony conviction probability to examine the impact of punishment severity on criminal behavior. In the theft value


Under the Cover of Darkness: Using Daylight Saving Time to Measure How Ambient Light Influences Criminal Behavior
We use data from the National Incidence-Based Reporting System (NIBRS) to examine how the probability of getting caught when committing a crime, proxied by ambient daylight, impacts criminal
Are Idle Hands the Devil's Workshop? Incapacitation, Concentration and Juvenile Crime
This paper examines the short-term effect of school on juvenile crime. To do so, we bring together daily measures of criminal activity and detailed school calendar information from 29 jurisdictions
Does Daylight Saving Time Save Energy? Evidence from a Natural Experiment in Indiana
Abstract We take advantage of a natural experiment in the state of Indiana to estimate the effect of daylight saving time (DST) on residential electricity consumption. Our main finding is that,
