Economics Detective Radio

This week's episode is a little different. There's an ongoing controversy related to a two-time guest of this show, Robin Hanson. I talk through the scandal, giving a whole decade of background so you can understand where this scandal comes from. There are many links for this episode. Here they are in the order they are discussed: Robin Hanson's books, The Age of Em and The Elephant in the Brain. "Unequal Beauty Silence" October 19, 2009 "Pretty Smart Healthy Privilege" September 26, 2014 "Inequality Talk Is About Grabbing" August 7, 2013 "Two Types of Envy" April 26, 2018 "Redistribution" means "change the distribution". A great many who have commented can't imagine any policy options to change the distribution of sex access other than rape and slavery, and so accuse me of advocating such things. But a great many other policy options exist. — Robin Hanson (@robinhanson) April 28, 2018 "it’s not hard to come away with the impression that [Hanson] believes men are owed sex, that women are devious about it,

Andrea Matranga of the New Economics School in Moscow joins the podcast with a fascinating question: Why did humans adopt agriculture in the times and places they did? His research paper, The Ant and the Grasshopper: Seasonality and the Invention of Agriculture, offers a potential solution. Here's the abstract: During the Neolithic Revolution, seven populations independently invented agriculture. In this paper, I argue that this innovation was a response to a large increase in climatic seasonality. Hunter-gatherers in the most affected regions became sedentary in order to store food and smooth their consumption. I present a model capturing the key incentives for adopting agriculture, and I test the resulting predictions against a global panel dataset of climate conditions and Neolithic adoption dates. I find that invention and adoption were both systematically more likely in places with higher seasonality. The findings of this paper imply that seasonality patterns 10,000 years ago were amongst the major deter

My guest today is Ryan Muldoon of the University at Buffalo. He is the author of Social Contract Theory for a Diverse World: Beyond Tolerance. We discuss the role of perspective diversity in political philosophy, with reference to both Ryan's book and his article, Diversity and Disagreement are the Solution, Not the Problem. We relate the philosophy to political divides in the real world, such as the rise of nationalist movements in Europe.  

The assiduous Vincent Geloso returns to the podcast to discuss his work with Rosolino Candela on lightships and their importance in economics. The abstract of their paper reads as follows: What role does government play in the provision of public goods? Economists have used the lighthouse as an empirical example to illustrate the extent to which the private provision of public goods is possible. This inquiry, however, has neglected the private provision of lightships. We investigate the private operation of the world’s first modern lightship, established in 1731 on the banks of the Thames estuary going in and out of London. First, we show that the Nore lightship was able to operate profitably and without government enforcement in the collection of payment for lighting services. Second, we show how private efforts to build lightships were crowded out by Trinity House, the public authority responsible for the maintaining and establishing lighthouses in England and Wales. By including lightships into the broader

My guest for this episode of Economics Detective Radio is Bart Wilson of Chapman University. He is the author of many experimental economics studies. Our conversation today focuses on one particular study entitled Language and cooperation in hominin scavenging. The abstract reads as follows: Bickerton (2009, 2014) hypothesizes that language emerged as the solution to a scavenging problem faced by proto-humans. We design a virtual world to explore how people use words to persuade others to work together for a common end. By gradually reducing the vocabularies that the participants can use, we trace the process of solving the hominin scavenging problem. Our experiment changes the way we think about social dilemmas. Instead of asking how does a group overcome the self-interest of its constituents, the question becomes, how do constituents persuade one another to work together for a common end that yields a common benefit? You can view a video demonstration of the experimental software here. The animation is qui

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 e

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.  

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 prohibiti

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. Signalling plays an important role in Bryan's understanding of the education system. He sees the causal effect of education on income as being 80 percent signalling and 20 percent learning. Most signalling models view signalling as negative sum: signals are costly, and to the extent that they help educated workers by pushing their resumes to the top of the pile, the

Today's guest is Russ Roberts, host of the quintessential economics podcast EconTalk. (If you haven't heard EconTalk, go subscribe to it right now, because it is excellent!) We discuss EconTalk's role in the economics profession, the things Russ has learned in the course of making it, the importance of intellectual honesty, and the enduring insights of Adam Smith. Here's the EconTalk interview with Bryan Caplan that I mentioned in the episode. Stay tuned for my own interview with Bryan!

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

Sam Hammond returns to the podcast today to discuss the free market welfare state. He and Will Wilkinson have both written articles in this area recently, and we discuss some of the concepts they bring up. People tend to think of government functions on a one-dimensional spectrum with "big government" on one end and "small government" at the other. Sam points out that the welfare state is separable from the other functions of government (regulation, command and control, protectionism, etc.). Not only is this true in theory, but it is played out in practice, with Nordic countries having very large welfare states as well as high economic freedom. We discuss some of the problems with current welfare states and some ways to improve them.

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. Here's Lynn Arditi's article on the accidental decriminalization of prostitution in Rhode Island. Scott mentions John Snow, the scientist who first discovered that cholera was spread by contaminated water sources. Here's the first video in a series on him.  

My guest today is Lyman Stone. He is an agriculture economist for the USDA, but our topic for this episode is his popular writing about migration. He blogs at In a State of Migration on Medium and co-hosts the podcast Migration Nation. We discuss the history of migration restrictions in the United States, the economic impact of migration between and within nations, and the relationship between falling fertility and immigration. The Great Baby Bust of 2017 "Economics and Emigration: Trillion-Dollar Bills on the Sidewalk?" by Michael A. Clemens (2011) "Does Mass Immigration Destroy Institutions? 1990s Israel as a Natural Experiment" by Benjamin Powell, J.R. Clark, and Alex Nowrasteh (2017)  

This episode of the podcast features two guests, Zach and Kelly Weinersmith. Zach is the author of SMBC Comics, a popular webcomic that sometimes deals with advanced concepts in science, philosophy, economics, and other fields. Kelly is a professor in the Biosciences department of Rice University. Together they co-authored Soonish: Ten Emerging Technologies That'll Improve and/or Ruin Everything. To quote the book's description, In this smart and funny book, celebrated cartoonist Zach Weinersmith and noted researcher Dr. Kelly Weinersmith give us a snapshot of what's coming next--from robot swarms to nuclear fusion powered-toasters. By weaving their own research, interviews with the scientists who are making these advances happen, and Zach's trademark comics, the Weinersmiths investigate why these technologies are needed, how they would work, and what is standing in their way. In this fun and lively conversation, we discuss some of the technologies discussed in the book: space elevators, asteroid mining, aug

My guest on this episode is Shruti Rajagopalan of the State University of New York's Purchase College. We discuss Shruti's work on constitutional political economy as it relates to India. We start by talking about the Indian constitution. India got its independence in 1947 and ratified a constitution shortly after in 1949. Interestingly, it is the most amended constitution in the world. Shruti argues "that the formal institutions of socialist planning were fundamentally incompatible with the constraints imposed by the Indian Constitution." We go on to discuss Shruti's work on the Bhopal gas tragedy, which demonstrates some of the failings of India's institutions. The Bhopal gas tragedy was a man-made disaster in 1984 where mishandling of dangerous chemicals by the company Union Carbide resulted in thousands of deaths and hundreds of thousands of non-fatal injuries among the public. The Indian government mismanaged the legal cases against Union Carbide, resulting in no payout to the people affected by the disa

Robin Hanson returns to the podcast to discuss his new book, The Elephant in the Brain: Hidden Motives in Everyday Life, co-authored with Kevin Simler. As the subtitle suggests, the book looks at humans' hidden motives. Robin argues that these hidden motives are much more prevalent than our conscious minds assume. We are not conscious of the vast majority of the functions of our brains. This extends beyond the most basic things our brains do (such as commanding our hearts to beat every second or so) to many things we think of as higher-level cognitive tasks. Hanson and Simler argue that, if the brain were a corporation, the conscious mind wouldn't be the CEO but the press secretary. Most of the reasons our conscious brains give for our actions are actually ex-post rationalizations for decisions that have been made unconsciously and for reasons that aren't immediately obvious to us. As a press secretary, the conscious mind is better off not knowing if we are doing things for selfish reasons since that would m

My guest for this episode is Ennio Piano of George Mason University. Our topic is Ennio's work on the economics of biker gangs. Ennio has two papers on this subject. The first, published in Public Choice, is entitled Free riders: the economics and organization of outlaw motorcycle gangs and it describes the franchise-style model of the Hell's Angels motorcycle gang, and how that model contributed to that gang's rise to prominence. By making the local chapters of the Hell's Angels residual claimants, while the head chapter in Oakland is responsible for the gang's name and reputation, the gang exploits local knowledge while also coordinating activities internationally. The second paper, Outlaw and economics: Biker gangs and club goods describes how the norms and rituals of biker gangs fit with the theory of club goods. Costly, unreliable motorcycles and even Nazi tattoos can be explained through this theory: they are credible commitments to remain loyal to the club. This behaviour is similar in purpose to ritua

My guest today is Jake Meyer of California State University, Long Beach. We discuss Jake's work on the intersection of financial crises and politics. Jake's work explores important questions such as the interaction between interest group politics and financial and currency crises. A country's monetary authority needs to manage both the domestic labour market and the country's exchange rate, but particular interest groups tend to favour one over the other very strongly. If one of these interest groups becomes disproportionately influential in national politics, they can affect monetary policy in ways that lead to crises. For instance, if a group that cares about the domestic economy and not the exchange rate takes power, they can push the monetary authority into causing an exchange rate crisis. If a group that cares exclusively about the exchange rate takes power, they can push the monetary authority to ignore the domestic economy to the point that it causes a banking crisis. Jake's work also looks at the way

Today's guest is Kyle Coates and our topic is pro wrestling and the intellectual property problems that arise from it. So prepare to be amazed as we BODY SLAM this topic, or something. Who owns a wrestler's name, gimmick, and persona? Kyle was inspired to do research in this area when he heard about a legal dispute between the wrestlers Jeff and Matt Hardy and the wrestling network TNA. The Hardys changed networks and wanted to continue using a gimmick they had developed while performing for TNA. We discuss some of the lawsuits and disputes that have occurred in the pro wrestling sphere, and how to courts have treated these issues. And yes, we answer the most important question: If Dwayne "The Rock" Johnson runs for President, will he be able to use Rock puns in his campaign ads? Listen to the episode to learn the answer!
