This story from Alex Tabarok on a study by Cui, Li and Zhang come to remarkably similar results to a previous study on ban the box laws in hiring

We conduct four randomized field experiments among 1,801 hosts on Airbnb by creating fictitious guest accounts and sending accommodation requests to them. We find that requests from guests with African American-sounding names are 19.2 percentage points less likely to be accepted than those with white-sounding names. However, a positive review posted on a guest’s page significantly reduces discrimination: When guest accounts receive a positive review, the acceptance rates of guest accounts with white-sounding and African American-sounding names are statistically indistinguishable.

This is modest good news.  It means that the original discrimination observed against people using Airbnb with black names had more to do with perceptions or stereotypes of unknown black people (e.g. "maybe they are more likely to be a criminal") than an out-and-out attitude of not wanting to have blacks set foot in their house.  The former is not great but a hell of a lot easier to combat than the latter.  I would argue the breakthrough in attitudes on gay marriage had a lot to do with so many people coming out of the closet over the last decade or two that almost everyone ended up having friends or family who were gay, and who they knew first hand to be good people.  This overcame past attitudes about homosexuality which for many were based wholly on stereotypes within their local circle.

As I linked above, this result in the Airbnb study was similar to a study on how ban the box had the perverse effect of reducing hiring of African-Americans because it reduced information:

Jurisdictions across the United States have adopted “ban the box” (BTB) policies preventing employers from asking about job applicants’ criminal records until late in the hiring process. Their goal is to improve employment outcomes for those with criminal records, with a secondary goal of reducing racial disparities in employment. However, removing criminal history information could increase statistical discrimination against demographic groups that include more ex-offenders. We use variation in the timing of BTB policies to test BTB’s effects on employment. We find that BTB policies decrease the probability of employment by 3.4 percentage points (5.1%) for young, low-skilled black men.

In that case as well, when no information is available, people fall back on stereotypes.  Employers recognized that stereotypes about criminal behavior were weak information and readily overcame them when better information (e.g. background checks) were available.

From the recently released study, "The Unintended Consequences of 'Ban the Box': Statistical Discrimination and Employment Outcomes When Criminal Histories Are Hidden"

Jurisdictions across the United States have adopted “ban the box” (BTB) policies preventing employers from asking about job applicants’ criminal records until late in the hiring process.

This is a pretty predictable outcome, and one that was discussed in my recent paper "How Labor Regulation Harms Unskilled Workers."  The effects of these regulations are synergistic.  Taken alone, one might expect this outcome from ban-the-box.  But combine it with minimum wage laws, rules that increase the monetary risk to employers for hiring unsuitable employees, and the increased regulatory difficulty in terminating employees (particularly minorities) and the effect is likely greater.  I explain this all in depth in the paper but here is a taste:

It used to be that the worst human resource risk a company faced was hiring employees who simply did not justify their salary. However, given the current body of regulation, any poorly selected employee is a potential ticking bomb who, through bad behavior with customers or other employees, could tie up the company for years in expensive litigation or regulatory actions. But as a firm’s liability for the negative activity of a poorly chosen
employee rises, regulations are making it harder to get good information to make better hiring choices,while simultaneously making it harder to terminate employees who were poorly chosen and present threats to the workplace or customers. When employers begin to look at their employees not as valuable assets but as potential liabilities, fewer people are going to be hired.

One potential way employers can manage this risk is to shift their hiring from unskilled employees to college graduates. Consider the risk of an employee making a racist or sexist statement to a customer or coworker (and in the process creating a large potential liability for the company). Almost any college graduate will have been steeped in racial and gender sensitivity messages for four years, while an employer might have an hour or two of training on these topics for unskilled workers. Similarly, because good information on prospective employees—credit checks, background checks,reference checks, discussions of past employment and salary—all have new legal limitations, employers who hire college graduates benefit from the substantial due diligence universities perform in their admissions process.

I made a vow a while back to try to get better at appealing to progressives using their assumptions, not mine.  So here is my shot at it here.  Prejudice exists among some employers that hold a stereotype of African-Americans as disproportionately criminal.  The best way to fight prejudice is through information and education.  But ban-the-box laws and other restrictions on background checks do just the opposite -- they restrict information.  Employers who see full criminal record information, say for African-American applicants, will be struck by how few have criminal records.  "Hey, these guys are OK," I can imagine someone saying.  Without this information, all that the employer has to work with are his pre-existing prejudices and misinformation, and in that context he might avoid African-Americans thinking "they are probably all criminals."
