How we tax property, with Lars Doucet

Fraud levels are a policy choice

In this episode, Patrick McKenzie (patio11) offers a reading of his viral essay, "The optimal amount of fraud is non-zero" with extensive live commentary. Patrick examines payment systems, benefits programs, and pandemic-era policies, to uncover how businesses and governments often intentionally accept some level of fraud as a cost of doing business. Reducing fraud to zero would require such restrictive verification that it would severely hamper legitimate commerce and social programs. Using examples from credit card processing to PPP loans, Patrick illustrates how different industries calibrate their tolerance for fraud based on their margins, mission, and societal role. – Full transcript available here: https://www.complexsystemspodcast.com/fraud-choice-patrick-mckenzie – Sponsor: GiveWell | Check Support proven charities that deliver measurable results and learn how to maximize your charitable impact with GiveWell.

Boom, busts, and long term progress with Byrne Hobart

By popular demand, Patrick McKenzie (patio11) is joined by Byrne Hobart for a 3rd conversation to discuss Byrne’s book "Boom: Bubbles and the End of Stagnation." They explore how periods of irrational market enthusiasm often create lasting value despite their painful endings. Using examples from the 1990s fiber optic boom that enabled modern streaming to today’s AI investment surge, they examine how even when investment manias end badly, they frequently pull forward crucial technological development that benefits society long-term. Byrne and Patrick weave through historical cases like Bell Labs to present day examples in crypto and energy infrastructure, revealing hidden cycles where speculative excess can drive genuine innovation. – Full transcript available here: https://www.complexsystemspodcast.com/episodes/boom-busts-and-long-term-progress-with-byrne-hobart-2/ – Sponsor: Check Check is the leading payroll infrastructure provider and pioneer of embedded payroll.
