Michael Munger on Middlemen

Episode Summary

Executive Summary: Russ Roberts and Mike Munger examine why middlemen are often disliked yet economically essential. Using a 1,000-year-old Anglo-Saxon text, a POW camp trading experiment, Bastiat, and the 2008 financial crisis, they argue middlemen create value by reducing transaction costs, aggregating information, managing risk, and enabling price discovery—though they can also harm markets when they seek protection from competition or from risk.

Main Topics: What a middleman does (Priority: 5/5): Munger defines middlemen as people who buy cheap and sell dear without changing the product, a definition that captures why they are often viewed skeptically. He argues that despite the negative reputation, middlemen are widespread and often indispensable. The Anglo-Saxon 'mankgear' text (Priority: 4/5): Munger uses a 1,000-year-old text describing a merchant who imports goods across dangerous seas and profits by resale. The passage highlights transport risk, arbitrage, and the moral suspicion attached to profit-seeking. POW camp exchange and price discovery (Priority: 5/5): Radford’s POW camp article is used as a natural experiment showing how voluntary exchange emerges from identical endowments and different preferences. Middlemen and arbitrageurs help create information about prices and scarcity. Bastiat and the fallacy of the state as substitute middleman (Priority: 5/5): Bastiat’s essay is used to challenge the idea that the state can simply replace private traders. Munger argues private merchants have incentives and local knowledge that bureaucracies lack, making them more effective at transport and allocation. Dynamic costs, incentives, and knowledge (Priority: 5/5): The discussion emphasizes that transport and exchange are not static technical problems. Profit incentives drive continual cost reduction, adaptation to changing relative prices, and discovery of better methods that a state provider would not replicate well. Financial middlemen, derivatives, and the 2008 crisis (Priority: 5/5): The hosts connect middlemen to Wall Street, Fannie Mae, Freddie Mac, and mortgage derivatives. They distinguish between productive financial intermediation and dangerous structures that encourage excessive risk-taking, opacity, and systemic contagion. Limits of historical explanation (Priority: 3/5): They close by noting that crises like the Great Depression and the 2008 meltdown are hard to explain ex post. Economics can identify some mistakes and incentives, but narratives are often incomplete and politically contested.

Key Arguments: Middlemen are not useless skimmers; they often create value by solving problems of transport, information, timing, and matching diverse preferences. The POW camp example shows that trade can increase welfare even when total physical goods are fixed, because exchange reallocates existing goods to higher-valued uses. Private traders have stronger incentives than the state to minimize costs, search for better prices, and innovate continuously. A large part of what middlemen do is unseen: they create markets, reduce transaction costs, and discover prices that help everyone make better decisions. The state cannot simply replace middlemen because it lacks profit incentives, local knowledge, and the discipline of competition. Middlemen can also be harmful when they seek to prevent competition rather than lower costs, or when financial intermediaries take on hidden systemic risk. The 2008 crisis was not simply a market failure; it reflected a hybrid system of government guarantees, regulatory distortions, and mistaken risk assumptions. Derivative markets differ from simple barter markets because prices were less stable, the underlying risks were opaque, and interconnected financial claims made failures contagious. Economic explanations are often retrospective and contested; crises rarely have a single clean cause.

Data Points: Date of recording: October 20, 2008 - Russ Roberts notes the episode is being taped during the financial crisis. Age of Anglo-Saxon text: about 1,000 years old - Munger cites a manuscript from around 1050 describing the merchant/monger. Radford article publication year: 1945 - The Economic Organization of a POW Camp is introduced as a key reference. POW camp year: 1943-1944 - The camp setting for Radford’s exchange experiment. Red Cross packet contents: 10 or 12 items - Each prisoner received the same standardized parcel with goods like beef, carrots, chocolate, cigarettes, and toilet paper. Debate date: October 29, 2008 - Munger mentions a forthcoming debate with Bill McKibben at the University of Vermont. Debate timing: late afternoon - Munger specifies the approximate time of the debate. Webvan loss rate: 90% of profits per year - Munger says the company was losing heavily while trying to eliminate the middleman. Webvan order size: $1 billion - He cites a billion-dollar warehouse build-out as part of the failed strategy. Black-Scholes Nobel Prize: a Nobel Prize in economics - Munger references controversy over the award tied to the model.

Pivotal Quotes: "I say I am useful to the king and to eldermen and to the rich and to all people." — Mike Munger: From the Anglo-Saxon merchant text, illustrating the merchant’s self-defense of his role. "When the hungry stomach is at Paris and corn, which can satisfy it, is at Odessa, the suffering cannot cease till the corn is brought into contact with the stomach." — Mike Munger: Bastiat quote used to explain why intermediaries exist and why transport matters. "The real thing that middlemen do is find ways to return cost." — Mike Munger: Core argument that the most important service of middlemen is lowering transaction and transport costs.

Implications: Listeners should view middlemen as a necessary part of market coordination, not just parasites. But they should also watch for intermediary structures that suppress competition, hide risk, or become politically protected.
