Refugee Waves, Mass Immigration, and Jordan with Alex Nowrasteh and Andrew Forrester

My guests for this episode are Alex Nowrasteh and Andrew Forrester of the Cato Institute. Our topic is a working paper they recently published titled How Mass Immigration Affects Countries with Weak Economic Institutions: A Natural Experiment in Jordan. The abstract reads as follows:

Saddam Hussein’s unexpected 1990 invasion of Kuwait forced 300, 000 Kuwaitis of Palestinian descent to flee into Jordan. By 1991, this large exogenous population shock increased Jordan’s population by about 10 percent. Jordanian law allowed these refugees to work, live, and vote in Jordan immediately upon entry. The refugees did not bring social capital that eroded Jordan’s institutions. On the contrary, we find that Jordan’s economic institutions substantially improved in the decade after the refugees arrived. Our empirical methodology employs difference-in-differences and the synthetic control method, both of which indicate that the significant improvement in Jordanian economic institutions would not have happened to the same extent without the influx of refugees. Our case study indicates that the refugee surge was the main mechanism by which Jordan’s economic institutions improved over this time.

Universities, Adjuncts, and Public Choice with Phil Magness

Phil Magness returns to the podcast to discuss the public choice economics of universities. We discuss the internal politics of universities, their rising reliance on adjunct scholars to teach courses, the increasing numbers of administrators staffing universities, and the trends in faculty employment across disciplines.

Prohibition, Arkansas, and Bootleggers and Baptists with Jeremy Horpedahl

Today’s guest is Jeremy Horpedahl of the University of Central Arkansas. Jeremy’s work builds on a famous theory from Bruce Yandle’s 1983 article ” Bootleggers and Baptists-The Education of a Regulatory Economist.” The article explored the idea that laws are often passed or defended by coalitions of economic interests (bootleggers) and moral crusaders (Baptists). Though these two groups may be quite different, as in the canonical example, policies are unlikely to succeed without support from both groups.

Jeremy’s work focuses on a particular example of bootleggers and Baptists in the modern world; specifically in Arkansas. Arkansas has many dry counties, where alcohol may not be sold. Many of these dry counties are adjacent to wet counties, where liquor stores just across the county line can sell to the residents of the dry county. When there are ballot initiatives to make dry counties wet, these liquor stores have the most to lose, so they often spend hundreds of thousands of dollars to prevent the prohibition laws from going to a vote.

The Case Against Education with Bryan Caplan

My guest for this episode is Bryan Caplan of George Mason University. We discuss his latest book, The Case Against Education: Why the Education System Is a Waste of Time and Money, in which he argues that the social value of education is negative.

This may seem paradoxical given that more educated individuals tend to earn more than less educated individuals. This can be explained in two ways: First, people who get more education were likely more skilled in the first place; in other words, there is a selection effect. Second, people who are already skilled can use education to demonstrate their skill to employers; economists call this signalling. Continue reading The Case Against Education with Bryan Caplan

Algorithms, Algorithmic Discrimination, and Autonomous Vehicles with Caleb Watney

Algorithms, Algorithmic Discrimination, and Autonomous Vehicles with Caleb Watney

Today’s guest is Caleb Watney of the R Street Institute. In our conversation, we discuss algorithms, particularly with respect to their role in judicial decision making. Later in the conversation, we discuss the algorithms that will one day replace ape brains as the primary controllers of our cars.

Caleb wrote a Cato Unbound essay in response to an article by Cathy O’Neil. O’Neil, a mathematician, argues that algorithms could potentially lead us astray. Her book Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy has sounded the alarm about the potential harms of an over-reliance on algorithms.

In Caleb’s view, O’Neil has pushed too far in the anti-algorithm direction. He points out that private companies have used algorithms to generate amazing innovations. Government is a different story:

“The most compelling concerns about the improper use of AI and algorithms stem primarily from government use of these technologies. Indeed, all the tangible examples of harm O’Neil cites in her essay are the result of poor incentives and structures designed by government. Namely, hiring models at a public teaching hospital, teacher value-added models, recidivism risk models, and Centrelink’s tax-fraud detection model. The poor results of these kinds of interactions, in which governments purchase algorithms from private developers, could be viewed primarily as a failure of the government procurement process. Government contracting creates opportunities for rent-seeking, and the process doesn’t benefit from the same kinds of feedback loops that are ubiquitous in private markets. So it should be no surprise that governments end up with inferior technology.”

We discuss the merits and demerits of algorithms, how different private and public incentives interact with algorithms, and the difficulties in creating algorithms that can be fair and transparent. Caleb’s ultimate solution for many of the problems associated with algorithms used by the government is for those algorithms to be open source in order to foster public scrutiny of their processes and outcomes.


During the conversation, Caleb alludes to this paper by Kleinberg, Mullainathan, and Raghavan, which shows that there are three competing definitions of algorithmic fairness that cannot all be achieved simultaneously.

Sex Work, Craigslist, and Decriminalization with Scott Cunningham

My guest for this episode is Scott Cunningham of Baylor University. We discuss his work on the decriminalization of indoor sex work and on the impact of Craigslist’s erotic services page on violence against women.

The working paper on Craigslist generated a lot of media attention, with articles at Huffington Post and ThinkProgress. The most quoted statistic is that “Craigslist erotic services reduced the female homicide rate by 17.4 percent.” We discuss this statistic, its possible causes, and whether or not it is implausibly large. Continue reading Sex Work, Craigslist, and Decriminalization with Scott Cunningham
