Can economics save the world? (with Erik Angner)

Episode Summary

Executive Summary: The episode argues that economics, when treated as an empirical and ethical science rather than a rigid ideology, can meaningfully improve society. Guest Erik Agner defends economics as a tool for solving problems like poverty and climate change, while Hanauer and Goldstein stress that economics must be reformed, interdisciplinary, and grounded in real human behavior, values, and public purpose.

Main Topics: Economics as a tool for public good (Priority: 5/5): Agner argues economics can help solve major social problems if used responsibly, analogizing it to medicine: useful, imperfect, and dependent on good practice and complementary supports. Critique of mainstream and media economics (Priority: 5/5): The hosts and guest distinguish serious economics research from textbook neoclassical models and TV punditry, arguing that public perceptions are shaped by a narrow set of ideological voices rather than the profession as a whole. Interdisciplinary economics and philosophy (Priority: 4/5): Agner emphasizes that economics must be joined with philosophy, ethics, and aesthetics because policy choices inevitably involve judgments about what a good life and good society are. Scarcity as a psychological constraint (Priority: 5/5): A major discussion focuses on scarcity not just as lack of resources, but as a felt sense of insufficiency that impairs cognition and traps people in poverty; policy should reduce scarcity stress, not intensify it. Childcare, labor force participation, and middle-out economics (Priority: 4/5): Using childcare in Sweden as an example, the conversation shows how public childcare can make work feasible, improve family well-being, and expand labor supply in an economically efficient and humane way. Climate change and carbon taxation (Priority: 4/5): Agner cites broad economist agreement on carbon taxes as a realistic climate policy, arguing that evidence-based economic consensus deserves more public attention and political traction. Humility, modeling, and scientific realism (Priority: 3/5): The discussion closes by defending economics as a science that should be judged by what its models predict or explain, while also acknowledging that many current economic assumptions and applications are inadequate.

Key Arguments: Economics should be judged as a science with real-world utility, not dismissed because of bad actors or simplistic textbook versions. The economics profession and its media-facing representatives are not the same; hired guns and self-promoters distort public understanding of the field. Values are unavoidable in policy; economics cannot be implemented without ethical and philosophical judgments about goals and tradeoffs. Scarcity is not only material shortage but also a psychological state that reduces rational decision-making and can perpetuate poverty. Policies that make poor people’s lives harder often worsen outcomes; reducing stressors like unaffordable childcare can improve employment and well-being. Public childcare is economically efficient because it enables more people, especially parents, to work and use their skills productively. Carbon taxes are one of the strongest areas of economist consensus and could be part of a workable climate strategy. Better economics requires empirical realism, interdisciplinary collaboration, and greater humility about model limitations.

Data Points: Podcast tenure: Almost 9 years - Nick Hanauer says it has been nearly nine years since he brought David Goldstein on to help redefine capitalism. Minimum wage policy shift: $15 minimum wage - Presented as an example of an idea that went from being seen as “the world’s dumbest idea” to common sense. Childcare cost in Fairfax, Virginia: $1,100 per child per month - Agner describes the cost of childcare when he lived in the D.C. area. Total childcare cost for three children: $3,300 per month - Agner calculates the monthly cost for three children in childcare. Break-even income estimate: About $5,000 per month - Agner says a junior academic might need to earn this much just to cover childcare costs. Swedish childcare cost for middle class: About $100 per month - Agner says childcare in Sweden is effectively free for poor families and low-cost for solidly middle-class families. Daycare staffing ratio example: 1 staff member for 8 kids - Agner uses this to illustrate why organized childcare is more efficient than parents staying home individually. Climate economist consensus: Thousands of economists - Agner cites an open letter signed by thousands of economists, Nobel laureates, and Fed officials supporting carbon taxation. Time horizon since economics shift: 40–50 years - Hanauer says economics has steered the world in the wrong direction for the last 40 or 50 years. Policy response window: Short term - Agner says carbon taxes could be implemented at least in the short term, even if not immediately tomorrow.

Pivotal Quotes: "Economics is too important to be left to economists." — Erik Agner: Agner describes the need for interdisciplinary collaboration and ethical reflection in policymaking. "The poorer you are, the greater the sense of scarcity, the harder it's going to be to act in a way to get you out of poverty." — Erik Agner: He explains how psychological scarcity can trap people in poverty and why support like childcare matters. "Dismissing it wholesale is positively harmful." — Erik Agner: Agner argues against rejecting economics entirely despite criticizing the profession.

Implications: Listeners are urged to see economics as a practical, reformable tool rather than a fixed ideology. The episode supports policies like childcare, carbon taxes, and interdisciplinary research that reduce scarcity, expand opportunity, and make markets serve human goals.
