Relevant and even prescient commentary on news, politics and the economy.

The Fed Credibility Argument

For once a short post, inspired by Simon Wren’s suggestion that the Fed should allow (encourage) a temporary rise in wage inflation. (The merits of such a policy being obvious to many of us given the current virtues of some extra inflation, and past decades’ wage trends.) I’ve never understood the credibility danger of the […]

Modeling the Price Mechanism: Simulation and The Problem of Time

Today’s New York Times article on rapid online repricing by holiday retailers depicts a retail world starting to approach the “flash-trading” status of financial markets: Amazon dropped its price on the game, Dance Central 3, to $24.99 on Thanksgiving Day, matching Best Buy’s “doorbuster” special, and went to $15 once Walmart stores offered the game […]

Does the Minimum Wage Increase Productivity?

This Galbraith article – pointing to Ron Unz’s ongoing good thinking on the topic, got me thinking: If employers are faced with higher wage rates, that gives them more incentive to invest in business capital that 1. makes workers more efficient and productive, and 2. reduces the number of workers they need. Is this incentive […]

The Efficiency of De Ebil Gubmint Man

I’ve pointed out before that in some areas (here, Medicare), government programs are hugely more efficient and well-run than their private counterparts. I don’t know if this qualifies as one of those, but it does make a very important point that I’ve also made before: Government is not the problem. Bad government is the problem. […]

Modeling the Wealth, Income, and "Saving" Effects of Redistribution: More is Better?

Update: More expansive discussion of this model with more graphics, here. Update 2: There is a revised and corrected version of the model and spreadsheet here, with discussion. It has long seemed to me that redistribution is, for some reason, necessary for the emergence, continuance, and growth of large, prosperous, modern, high-productivity monetary economies. No such economy […]

The Miasma School of Economics

I’ve been reading Steven Johnson’s The Ghost Map, about the London cholera epidemic of 1854, and one passage reminded me exactly of today’s economics discipline. The sense of similarity was heightened because I also (instigated by Nick Rowe) happened to be reading Mankiw’s micro textbook section on the rising marginal cost of production — a […]

Marginal Rates and Economic Growth: They Go Up Together

With Republicans frantically clinging to discredited ideology and digging in their heels on raising top marginal tax rates, I thought it would be worth revisiting a post from a couple of years ago, showing some excellent long-term evidence that higher marginal tax rates are not associated with slower growth. Quite the contrary, in fact. Here […]

It’s No Wonder People Don’t Understand the "Public" Debt

A friend of mine posted this on Facebook: I started to explain it, but realized that the standard usage is wildly screwy and confusing for any normal human, and decided to explain it here instead. The problem is that even in standard economists’ usage, “public” is used in two different ways: 1. “Public” debt: debt […]

Medium of Account vs Unit of Account: Brazil Anyone?

I’d like to interject a very concrete example into the large swirl of quite theoretical, thought-experiment discussion about whether “demand for money” means “demand for the medium of exchange” or “demand for the medium of account.” Scott Sumner and Nick Rowe are, as so often, at the center of this discussion. But before I do, […]
