Jane Jacobs as Spontaneous Order Theorist with Pierre Desrochers

This episode of Economics Detective Radio features Pierre Desrochers discussing the life and work of Jane Jacobs. Jacobs, born Jane Butzner, was a thinker and activist who wrote about cities. She spent her early career as a business journalist. When she started writing about urban renewal, she recognized the policy for the disaster it was. Jacobs became a voice for the general dissatisfaction with a policy that would bulldoze whole neighbourhoods, relocating the inhabitants into new buildings preferred by urban planning reformers and political elites.

The editors of Fortune Magazine invited Jacobs to write a piece about downtowns. Her piece, “Downtown is for People” became the magazine’s most-discussed article. She developed the ideas in that article into her first and most famous book, The Death and Life of Great American Cities. The book launched her as a minor celebrity.

In New York City, she successfully opposed initiatives to “renew” Greenwich Village. She also opposed a plan that would have cut a highway through SoHo, Chinatown, and Little Italy. Eventually she found herself opposing the Vietnam War, and, fearing that one of her sons would be drafted, moved to Toronto.

TruthCoin, Prediction Markets, and Anarchy with Zack Hess

This episode of Economics Detective Radio features Zack Hess. Zack is working on a project called “TruthCoin,” a decentralized prediction market based on the technology behind bitcoin.

Prediction markets are a highly effective way to bring together dispersed information and insight into prices that reflect the likelihood of any future event. However, recent attempts to create centralized prediction markets have been thwarted by governments under antiquarian anti-gambling laws.

Enter TruthCoin. TruthCoin is a prediction market (currently in beta) that will not depend on any central server or organization. This online market will be dispersed among all the participants and thus more difficult to shut down.

Furthermore, TruthCoin will not depend on a central arbiter. The main difficulty faced by the creators of TruthCoin is in creating incentives for human arbiters to judge the outcomes of bets correctly. The solution is for judges to be set against one another, for each judge to get a higher payoff when other judges are wrong. Then any attempted collusion between arbiters falls apart.

Vampires, Zombies, and the Dismal Science with Glen Whitman

In this episode, Glen Whitman discusses Economics of the Undead: Vampires, Zombies, and the Dismal Science, a book he co-edited with James Dow. Glen is an economics professor at California State University and, unlike most academic economists, he moonlights as a TV writer. He first wrote for the TV show Fringe and now writes for the soccer spy drama, Matador.

The book’s website provides the following description:

“Whether preparing us for economic recovery after the zombie apocalypse, analyzing vampire investment strategies, or illuminating the market forces that affect vampire-human romances, Economics of the Undead: Zombies, Vampires, and the Dismal Science gives both seasoned economists and layman readers something to sink their teeth into.

Undead creatures have terrified villagers and popular audiences for centuries, but when analyzed closely, their behaviors and stories—however farfetched—mirror our own in surprising ways. The essays collected in this book are as humorous as they are thoughtful, as culturally relevant as they are economically sound, and provide an accessible link between a popular culture phenomenon and the key concepts necessary to building one’s understanding of economic systems large and small. It is the first book to combine economics with our society’s fascination with the undead, and is an invaluable resource for those looking to learn economic fundamentals in a fun and innovative way.”

Migration and Open Borders with Nathan Smith

In this episode, Nathan Smith discusses the economics and history of migration and migration restrictions. Nathan is an Assistant Professor of Business Administration: Finance and Economics at Fresno Pacific University and regular blogger at Open Borders: The Case.

We start the episode by discussing the economic impacts of Nathan’s own migration to Fresno. Students gain, as he adds to the supply of economics professors, other economists might lose from his competition in labour markets, people looking for parking near the University might lose, as he slightly reduces the supply of available parking spaces, and property owners gain from his demand for housing. In general, anyone Nathan transacts with gains from the transaction, while those who he competes with may suffer some slight loss.

The big slogan among open borders advocates is that a significant reduction in migration restrictions could “double world GDP.” Nathan’s own most recent estimates show about a 91% increase world GDP, mainly because people would move from places where they can earn very little (e.g. places with dysfunctional institutions) to places where they can earn quite a bit more (e.g. places with well-functioning  institutions, complementary factors of production, highly developed networks of specialization and exchange, etc.). There are complementarities between human capital and unskilled labour. For instance, great managers are more productive when there are many workers to manage, and the workers are more productive where there are great managers.

Price Theory and the Minimum Wage

The minimum wage is a contentious issue among economists, and yet it enjoys near-universal support among the public. In my view, public views of the minimum wage are simply the result of a lack of careful thought by most people. Daniel Kahneman’s theory that people, when faced with a difficult question, substitute a simpler question that they can easily answer, applies particularly well in this case. People answer the question of whether they would like people to earn more when the real question is whether government should mandate higher wages (I first heard this argument from Bryan Caplan on EconLog).

A purely empirical argument for or against the minimum wage is methodologically wrong-headed because empirics do not speak for themselves. Sound theory must be the economist’s first tool in understanding the effect of a policy such as the minimum wage.

Before we can understand something like the minimum wage, we must understand the role of prices in allocating factors of production to their various uses. The price of a factor signals to entrepreneurs that that factor is scarce, that it is needed elsewhere in the economy, and that the entrepreneur who can reduce his usage of relatively more scarce factors in favour of relatively less scarce ones can earn profits, while entrepreneurs who fail to do so earn losses. I give the example of a sandwich shop during an oil boom; the high price of labour caused by the oil boom leads the sandwich shop to substitute away from labour in various ways.

Virginia Political Economy and Entrepreneurship with Diana Thomas

In this episode, Diana Thomas discusses the relationship between the Virginia School of Political Economy and the Austrian School of Economics. Diana is an Associate Professor of Economics at the Heider College of Business at Creighton University.

The Virginia School is a branch of public choice, the application of the tools and techniques of economics to the study of political actors. The Virginia School’s founders, James Buchanan and Gordon Tullock, were the first to systematically apply a rational choice framework to the study of politics in The Calculus of Consent.

Two assumptions commonly made by neoclassical economists are the “benevolence assumption” and the “omniscience assumption.” The benevolence assumption is implicit in normative analysis of what governments “ought” to do, as this assumes that political actors are motivated to maximize the common good rather than pursuing their self-interest. This assumption is challenged by public choice economists. The omniscience assumption is at play in economic models that depict the economy as being in equilibrium, whereby nobody is misinformed of or surprised by economic reality. This assumption is challenged by Austrian economists. Continue reading Virginia Political Economy and Entrepreneurship with Diana Thomas

Economic Calculation and Education

A key difference between Austrian economics and the neoclassical-mathematical economics developed in the mid-twentieth century by Paul Samuelson and others is the assumption by the latter that people are essentially omniscient. What neoclassical economists call “rationality” effectively means omniscience. When the agents in neoclassical models face any uncertainty, the uncertainty is always fully understood in advance; for instance, a stock’s value tomorrow might be drawn from a normal distribution with a known mean and variance. Without the assumption of omniscience, the Austrian school faces the important question of how people can make economic decisions in a complex, uncertain world.

Ludwig von Mises’ answer (see his 1920 essay, Economic Calculation in the Socialist Commonwealth) was that capitalist entrepreneurs calculate in monetary terms. That is, they use the prices of the immediate past as their starting data, and attempt to direct factors of production in such a way as to maximize the spread between costs and revenues. If their predictions of price changes are good, they earn profits. If their predictions are bad, they earn losses. Thus, their direction of scarce resources is subject to immediate and consequential feedback allowing a selective process for only the best entrepreneurial forecasting methods. Without monetary exchange and prices, the problem of directing factors of production to their highest uses becomes intractable.

An interesting thing about Mises’ calculation argument is that it does not only relate to socialism, but to free, capitalist societies also. Mises states that, “Economic goods only have part in this system [of monetary calculation] in proportion to the extent to which they may be exchanged for money.” Thus, when a good cannot be exchanged for money, for any reason, it is subject to a Misesian calculation problem.

The Austrian Cult and Mathematical Economics with Ash Navabi

In this episode, Ash Navabi discusses whether the Austrian School of Economics is a cult and the value of mathematics in economic theory. Ash is an economics student at Ryerson University.

Ash wrote an article responding to recent criticisms of the Austrian school by Keynesian bloggers Noah Smith and Paul Krugman. Krugman approvingly referenced Smith’s attacks on the “hermetic system that is Austrians.” Just a week later he made the following telling comment about the economics mainstream:

“And modern academic economics is very much an interlocking set of old-boy networks; to some extent this has become even more true since the decline of the journals, with most discourse taking place via working papers long before formal publication. I used to refer to the international trade circuit as the floating crap game — the same 30 or 40 people meeting in conferences all over the world, reading and citing each others’ work; it’s the same in each sub-field. And to some extent it’s inevitable: there’s so much stuff out there, and you have to filter somehow, so you mainly read stuff by people you know and people they tell you are worth reading.”

Ash was quick to point out that, by the logic of the people who deride Austrian economists as “cultish” because they interact mainly with one another, each of the “old-boy networks” Paul Krugman refers to (that is, each sub-field of mainstream economics) must also be a cult.

Gold and the Great Depression with James Caton

In this episode, James Caton discusses the classical and inter-war gold standards. James is an economics PhD student at George Mason University.

Gold has many qualities that make it an ideal money: It is valuable, scarce, divisible, and easy to transport. It is also easy to verify the value of a given amount of gold: The Old Testament references weights and scales being used to measure gold. Ancient people could verify the purity of the gold by observing its water displacement.

Before 1870, only Great Britain was on a gold standard, while gold, silver, and other metals would circulate freely alongside one another throughout the rest of Europe. The classical gold standard began in the wake of the Franco-Prussian War, when the victorious Germany demonetized silver in favour of gold and the rest of Western Europe followed suit (see Caton on the deflation that resulted from the demonetization of silver). America converted to the gold standard in 1879 upon redeeming the Civil War greenbacks for gold. Continue reading Gold and the Great Depression with James Caton

Simple Keynesianism

XKCD Comic about simple English Wikipedia
Source: http://xkcd.com/547/

Simple English Wikipedia is an edition of the open-source encyclopedia designed to be intelligible to small children, adults with learning disabilities, and people who are learning English.  It is also an entertaining read, because the simple language often makes things silly. I found the article on Keynesian economics to be particularly silly and entertaining:

Keynesian economics (also called Keynesianism) describes the economics theories of John Maynard Keynes. Keynes wrote about his theories in his book The General Theory of Employment, Interest and Money. The book was published in 1936.

Keynes said capitalism was a good economic system. In a capitalism system, people earn money from their work. Businesses employ and pay people to work. Then people can spend their money on things they want. Other people work and make things to buy. Sometimes the capitalism system has problems. People lose their work. Businesses close. People cannot work and cannot spend money. Keynes said the government should step in and help people who do not have work.

This idea is called “demand-side policy”. If people are working, the economy is good. If people are not working, the economy is bad.

Keynes said when the economy is bad, people want to save their money. That is, they do not spend their money on things they want. As a result there is less economic activity.

Keynes said the government should spend more money when people do not have work. The government can borrow money and give people jobs (work). Then people can spend money again and buy things. This helps other people find work.

Some people, such as conservatives, libertarians, and people who believe in Austrian economics, do not like Keynes’ ideas. They say government work does not help capitalism. They say when the government borrows money, it takes money away from businesses. They do not like Keynesian economics because they say the economy can get better without government help.

During the late 1970s Keynesian economics became less popular because inflation was high.

When a big recession happened in 2007, Keynesian economics became more popular. Leaders around the world (including Barack Obama) created stimulus packages which would allow their government to spend a lot of money to create jobs.

Hilarious!
