Picking Uncle Sam's pocket, with Jetson Leder-Luis

In this episode, Patrick McKenzie (patio11) is joined by economist and fraud researcher Professor Jetson Luis-Leder to examine the systemic issues underlying government program fraud. Jetson and Patrick discuss healthcare fraud cases, including hospice eligibility manipulation and ambulance transport schemes, and other fraud practices against unemployment and the PPP program. The discussion reveals how institutional constraints, technological limitations, and policy design choices create opportunities for both beneficial and harmful rule violations.

How real estate investing works with Moses Kagan

In this episode, Patrick McKenzie (patio11) is joined by Moses Kagan, co-founder of Adaptive Realty, ReSeed, and Reconvene. Their deep dive into real estate investing and property management covers the different classes of apartment buildings, the challenges of property management, and the complexities of financing structures in the industry. They examine how the internet has transformed capital raising, the significance of cap rates, the effects of supply and demand on property values, and a comparison of the real estate markets in different major cities. The episode is in many ways a follow up to Patrick’s conversation with Jim McKenzie and offers a window into the opaque world of real estate investment. – Full transcript available here: https://www.complexsystemspodcast.com/episodes/real-estate-moses-kagan/ – Sponsor: Check Check is the leading payroll infrastructure provider and pioneer of embedded payroll.

Telling the tech story

In this episode, Patrick McKenzie (patio11) and Erik Torenberg, investor and the media entrepreneur behind Turpentine, explore the evolving relationship between tech journalism and the industry it covers. They discuss how fictional portrayals of industries greatly inform how jobseekers understand those industries, and how the industries understand themselves. They cover the vacuum in quality tech reporting, the emergence of independent media companies, and industry heavyweights with massive followings. Patrick also brings up the phenomenon of Twitter/Slack crossovers, where coordinated social media action is used to influence internal company policies and public narratives. They examine how this dynamic, combined with economic pressures and ideological motivations, has led to increased groupthink in tech journalism. Expanding on themes covered in Kelsey Piper’s episode of Complex Systems, this conversation makes more legible the important ways media affects tech, even though tech is arguably a more sophisticated industry – and why there is a need to move beyond simplistic narratives of "holding power accountable" to provide nuanced, informative coverage that helps people understand tech’s impact on society. – Full transcript available here: https://www.complexsystemspodcast.com/episodes/tech-media-erik-torenberg –Sponsors: WorkOS | Check Building an enterprise-ready SaaS app?

Patrick McKenzie (patio11) is joined by his father, Jim McKenzie, for an intimate and in depth exploration of commercial real estate development.

Decisions Nobody Made, policy edition, with Dave Guarino

In this episode of Complex Systems, Patrick McKenzie (aka @Patio11) is joined by Dave Guarino, a software engineer and policy wonk. They explore the complexities and challenges of public programs, focusing on SNAP aka CalFresh in California, where Dave was the founding engineer and then director. They discuss how society’s complex preferences become policy, driving obviously bad UXes (like 200+ questions for an application) for structural reasons. Patrick and Dave debate structural issues within government agencies that lead to these inefficiencies, the lack of user-centric design, misaligned incentives, a “cavernous gap” in feedback loops, and surprisingly simple ways anyone can influence public policy and improve government systems. – Full transcript available here: https://www.complexsystemspodcast.com/episodes/government-software-dave-guarino/ – Sponsors: Check | WorkOS Check is the leading payroll infrastructure provider and pioneer of embedded payroll.
