The Effect of Undocumented Immigration and Border Enforcement on Crime Rates along the U.S.-Mexico Border
In the 1990s, the U.S. border led the nation in the decline of property-related crimes, while violent crime rates fell twice as fast in the U.S. as in the median border county. This paper asks how changes in undocumented immigration and border enforcement have played a role in generating these divergent trends. We find that while migrant apprehensions are correlated with a greater incidence of violent crime, they are not systematically associated with higher rates of property crime. Border patrol enforcement is associated with lower property crime rates but higher violent crime. ...

The Hidden Effects of Algorithmic Recommendations
Algorithms are intended to improve human decisions with data-driven predictions. However, algorithms provide more than just predictions to decision-makers—they often provide explicit recommendations. In this paper, I demonstrate these algorithmic recommendations have significant independent effects on human decisions. I leverage a natural experiment in which algorithmic recommendations were given to bail judges in some cases but not others. Lenient recommendations increased lenient bail decisions by 40% for marginal cases. The results are consistent with algorithmic recommendations making ...

Can Reputation Discipline the Gig Economy? Experimental Evidence from an Online Labor Market
Just as employers face uncertainty when hiring workers, workers also face uncertainty when accepting employment, and bad employers may opportunistically depart from expectations, norms, and laws. However, prior research in economics and information sciences has focused sharply on the employer?s problem of identifying good workers rather than vice versa. This issue is especially pronounced in markets for gig work, including online labor markets, where platforms are developing strategies to help workers identify good employers. We build a theoretical model for the value of such reputation ...

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 distribution between old and new larceny thresholds (“response region”), higher thresholds cause a 2 percent increase in the average larceny value within 120 days of enactment. However, within five years of enactment, response region average larceny values and rates decline 2 percentand 13 percent, respectively, in low-wage areas. Thus, under certain market conditions, smaller expected penalties ...

Information Production, Misconduct Effort, and the Duration of Corporate Fraud
We develop and test a model linking the duration of financial fraud to information produced by auditors and analysts and efforts by managers to conceal the fraud. Our empirical results suggest fraud termination is more likely in the quarter following the release of audited financial statements, especially when reports contain explanatory language, indicating auditors? observable signals reduce fraud duration. Analyst attention increases the likelihood of fraud termination, but the marginal effect beyond the first analyst is negative, possibly due to free riding and herding behavior impairing ...

A Model of Charles Ponzi
We develop a model of Ponzi schemes with asymmetric information to study Ponzi frauds. A long-lived agent offers to save on behalf of short-lived agents at a higher rate than they can earn themselves. The long-lived agent may genuinely have a superior savings technology, but may be an imposter trying to steal from short-lived agents. The model identifies when a Ponzi fraud can occur and what interventions can prevent it. A key feature of Ponzi frauds is that the long-lived agent builds trust over time and improves their reputation by keeping the scheme going.

The effect of changing employers’ access to criminal histories on ex-offenders’ labor market outcomes: evidence from the 2010–2012 Massachusetts CORI Reform
Many regard the 2010?2012 Massachusetts Criminal Offender Record Information (CORI)Reform as a national model to improve ex-offenders? labor market outcomes. This reform prohibits most employers from inquiring about an individual?s criminal history on the initial job application (the ?ban the box? reform), and reduces employers? access to an applicant?s criminal record (the record-access reform). Using the CORI Reform as a natural experiment and a unique large confidential dataset linking individuals? CORI records with their unemployment insurance quarterly wage records, we examine the impact ...

Does changing employers’ access to criminal histories affect ex-offenders’ recidivism?: evidence from the 2010–2012 Massachusetts CORI Reform
This paper examines how changes in employers? access to job applicants? criminal histories affect ex-offender recidivism. We use extensive state administrative data on individual criminal histories spanning the 2010?2012 Massachusetts Criminal Offender Record Information (CORI) Reform, widely regarded as landmark legislation governing access to individuals? criminal information. The CORI Reform: i) banned inquiring about criminal history on initial job applications, and ii) broadened the list of groups eligible to use the state?s criminal records repository while simultaneously restricting ...
