For most of the topics Roberts covers, no specialized knowledge is required. By now, everyone knows that driverless cars are coming. But in one of the first discussions of the technology, EconTalk considered not just how it would affect jobs (an estimated 3.5 million Americans are employed as truck drivers) but how it might change many aspects of life. If everyone had a driverless car, everyone would, in effect, have a chauffeur. Time spent commuting could become much more productive, as people worked on their laptops while being ferried to and from the office.
The podcast on price gouging laws should be required listening for every well-meaning politician. Duke University’s Mike Munger joined Roberts to discuss the effect of such laws after natural disasters like hurricanes. Bottom line: If prices are allowed to spike temporarily for essentials like gasoline, suppliers will have the incentive to invest in generators and so forth to provide them. The sooner gas is flowing, the sooner everyone’s power will be back up and running, at which time, prices will fall. Anti-gouging laws, though they sound good, actually prolong the crisis.
Often Roberts agrees with his guests, but when he doesn’t, he is the model of polite demurral. It’s a cliche that we should approach all subjects with an open mind, but to encounter Roberts is to realize, with force, how rare a truly open mind actually is.
On several podcasts, Roberts has explored the “replicability crisis” in psychology and other disciplines and biases of various kinds in economics, climate science, medicine and other fields. He’s also sensitive to the law of unintended consequences. One guest that I recall from a few years ago spoke of the irony that as we make appliances more energy efficient, we can actually increase energy usage rather than reducing it. Gas stations take advantage of the lower price of refrigerators, for example, by stocking more sodas and other drinks. Each refrigerator is more efficient than its predecessor, but the result can be more overall energy use.
Roberts is unyielding on the topic of the bank bailouts. Several podcasts have explored the run-up to the financial crisis of 2007-2008. Roberts’ explanation of how we came to be a country that privatizes bankers’ profits and socializes their losses is soon to be a book.
Though the podcast is titled “EconTalk,” it’s really about much more — from organ selling, to empathy (an overrated virtue, according to Paul Bloom), to how museums hoard art, to food waste (it’s OK!), to the moral (not just economic) insights of Adam Smith. The podcast stimulates the soul as well as the mind.
