Today’s guest is Jamin Speer of the University of Memphis. We discuss his paper, “Are Changes of Major Major Changes? The Roles of Grades, Gender, and Preferences in College Major Switching” co-authored with Carmen Astorne-Figari.

The choice of college major is a key stage in the career search, and over a third of college students switch majors at least once. We provide the first comprehensive analysis of major switching, looking at the patterns of switching in both academic and non-academic dimensions. Low grades signal academic mismatch and predict switching majors – and the lower the grades, the larger the switch in terms of course content. Surprisingly, these switches do not improve students’ grades. When students switch majors, they switch to majors that “look like them”: females to female-heavy majors, and so on. Lower-ability women flee competitive majors at high rates, while men and higher-ability women are undeterred. Women are far more likely to leave STEM fields for majors that are less competitive – but still somewhat science-intensive – suggesting that leaving STEM may be more about fleeing the “culture” of STEM majors than fleeing science and math.

Kevin Erdmann of the Mercatus Center returns to the podcast to discuss his new book, Shut Out: How a Housing Shortage Caused the Great Recession and Crippled Our Economy. From the publisher’s website:

The United States suffers from a shortage of well-placed homes. This was true even at the peak of the housing boom in 2005. Using a broad array of evidence on housing inflation, income, migration, homeownership trends, and international comparisons, Shut Out demonstrates that high home prices have been largely caused by the constrained housing supply in a handful of magnet cities leading the new economy.

The same phenomenon is occurring in leading countries across the globe. Gentrifying cities have become exclusionary bastions in the new postindustrial economy. The US housing bubble that peaked in 2005 is more accurately described as a refugee crisis than a credit bubble. Surging demand for limited urban housing triggered a spike of migration away from the magnet cities among households with moderate and lower incomes who could no longer afford to remain, causing a brief contagion of high prices in the cities where the migrants moved.

Today’s guest on Economics Detective Radio is Anja Shortland of King’s College London, discussing her new book Kidnap: Inside the Ransom Business, where she brings an economist’s perspective to the shady world of the kidnapping for ransom business and to the professionals who specialize in getting hostages home safely. The book’s description reads as follows:

Kidnap for ransom is a lucrative but tricky business. Millions of people live, travel, and work in areas with significant kidnap risks, yet kidnaps of foreign workers, local VIPs, and tourists are surprisingly rare and the vast majority of abductions are peacefully resolved – often for remarkably low ransoms. In fact, the market for hostages is so well ordered that the crime is insurable. This is a puzzle: ransoming a hostage is the world’s most precarious trade. What would be the “right” price for your loved one – and can you avoid putting others at risk by paying it? What prevents criminals from maltreating hostages? How do you (safely) pay a ransom? And why would kidnappers release a potential future witness after receiving their money?

Kidnap: Inside the Ransom Business uncovers how a group of insurers at Lloyd’s of London have solved these thorny problems for their customers. Based on interviews with industry insiders (from both sides), as well as hostage stakeholders, it uncovers an intricate and powerful private governance system ordering transactions between the legal and the criminal economies.
