The conversation dives into labor regulations, the complexities of employment, and the benefits of deregulating labor markets through immigration reform.

ANECDOTE

Race-Based Minimum Wage Example

Bryan Caplan uses the example of a $20 minimum wage exclusively for black workers to illustrate its potential harm.
Such a regulation might discourage hiring black workers, leading to unemployment.

INSIGHT

Labor Regulations Can Backfire

Labor regulations, while seemingly beneficial to workers, can backfire and decrease employment.
Consider the hypothetical "Bryan Caplan Protection Act", mandating a million-dollar hourly wage, to understand this.

INSIGHT

Non-Monetary Value of Work

Economists often overlook the non-monetary value of work, like social contact and purpose.
Unemployment causes significant misery, even with full income compensation, highlighting this.

A Mostly Common Sense Guide to Philosophy

Michael Huemer

This book provides a comprehensive guide to basic philosophical problems, including skepticism, free will, personal identity, and ethical theories like utilitarianism and deontology. It presents these complex topics in a clear and engaging way, making philosophy more accessible to readers.

Selfish reasons to have more kids

Bryan Caplan

The Nurture Assumption

Paula Parker

In 'The Nurture Assumption', Judith Rich Harris challenges the conventional wisdom that parents are the primary influence on child development. Instead, she posits that children's peers play a more significant role in shaping their behavior and personality. The book offers a compelling argument that reevaluates the traditional understanding of parental influence and highlights the importance of peer relationships in child development.

Working

people talk about what they do all day and how they feel about what they do

Studs Terkel

In 'Working,' Studs Terkel conducts in-depth interviews with people from diverse occupations, ranging from gravediggers to studio heads. The book provides a snapshot of American working life in the early 1970s, highlighting the emotional and physical aspects of work. It explores themes of job satisfaction, the search for meaning, and the impact of work on individuals' lives. The interviews are edited to preserve the voices and stories of the subjects, offering a powerful and original perspective on work and its significance in human experience.

The Case against Education

Bryan Caplan

In 'The Case Against Education,' Bryan Caplan argues that a significant portion of the benefits of education are not due to the acquisition of skills or knowledge, but rather to signalling preexisting abilities. He contends that this signalling effect is prevalent across all levels of education, from elementary school to graduate programs. Caplan supports his argument with extensive data, tables, and graphs, as well as personal anecdotes and observations. He also proposes alternative educational approaches, such as technical and vocational training, which he believes are more effective in improving worker productivity. The book is known for its provocative and well-argued critique of the current education system, suggesting reforms like reduced school time and relaxed child labor laws[1][3][4].

Why Americans Vote the Way They Do

Boris Shor

Jeronimo Cortina

Andrew Gelman

David K. Park

This book explores the complex relationship between income, geography, and voting patterns in the United States. It challenges common myths about political divisions and offers insights into why rich states tend to vote Democratic while rich individuals often vote Republican. The authors use statistical analysis to explain these patterns and their implications for American politics.

The Good

Iris Murdoch

Neighborhood Defenders

Katherine Levine Einstein

This book explores how 'neighborhood defenders,' often privileged homeowners, use land use regulations to limit housing supply, contributing to the affordable housing crisis. It highlights how participatory institutions can exacerbate inequality by allowing these defenders to delay or block new housing projects. The authors analyze data from public meetings and zoning regulations to demonstrate the impact on housing availability and costs.

Kelly & Zach Weinersmith

In 'Open Borders: The Science and Ethics of Immigration', Bryan Caplan and Zach Weinersmith make a compelling case for open borders, suggesting that unrestricted immigration could eliminate absolute poverty worldwide and boost the global economy. The book addresses common criticisms of immigration and presents its arguments in a clear and engaging graphic format.

Everybody knows that good parenting has a big impact on how kids turn out. Except that maybe they don't, because it doesn't.

Incredible though it might seem, according to today's guest — economist Bryan Caplan, the author of Selfish Reasons To Have More Kids, The Myth of the Rational Voter, and The Case Against Education — the best evidence we have on the question suggests that, within reason, what parents do has little impact on how their children's lives play out once they're adults.

Of course, kids do resemble their parents. But just as we probably can't say it was attentive parenting that gave me my mother's nose, perhaps we can't say it was attentive parenting that made me succeed at school. Both the social environment we grow up in and the genes we receive from our parents influence the person we become, and looking at a typical family we can't really distinguish the impact of one from the other.

But nature does offer us up a random experiment that can let us tell the difference: identical twins share all their genes, while fraternal twins only share half their genes. If you look at how much more similar outcomes are for identical twins than fraternal twins, you see the effect of sharing 100% of your genetic material, rather than the usual 50%. Double that amount, and you've got the full effect of genetic inheritance. Whatever unexplained variation remains is still up for grabs — and might be down to different experiences in the home, outside the home, or just random noise.

The crazy thing about this research is that it says for a range of adult outcomes (e.g. years of education, income, health, personality, and happiness), it's differences in the genes children inherit rather than differences in parental behaviour that are doing most of the work. Other research suggests that differences in “out-of-home environment” take second place. Parenting style does matter for something, but it comes in a clear third.

Bryan is quick to point out that there are several factors that help reconcile these findings with conventional wisdom about the importance of parenting.

First, for some adult outcomes, parenting was a big deal (i.e. the quality of the parent/child relationship) or at least a moderate deal (i.e. drug use, criminality, and religious/political identity).

Second, parents can and do influence you quite a lot — so long as you're young and still living with them. But as soon as you move out, the influence of their behaviour begins to wane and eventually becomes hard to spot.

Third, this research only studies variation in parenting behaviour that was common among the families studied.

And fourth, research on international adoptions shows they can cause massive improvements in health, income and other outcomes.

But the findings are still remarkable, and imply many hyper-diligent parents could live much less stressful lives without doing their kids any harm at all. In this extensive interview Rob interrogates whether Bryan can really be right, or whether the research he's drawing on has taken a wrong turn somewhere.

And that's just one topic we cover, some of the others being:

• People’s biggest misconceptions about the labour market
• Arguments against open borders
• Whether most people actually vote based on self-interest
• Whether philosophy should stick to common sense or depart from it radically
• Personal autonomy vs. the possible benefits of government regulation
• Bryan's perfect betting record
• And much more
