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

Not Spending is Not Investment

I see this logical error so constantly, almost every day, that I feel the need to reiterate. Personal saving, virtuous and useful as it is for individuals, does not increase investment. This is what I call the “lump of money” fallacy (a.k.a. the loanable funds model). Ask yourself: If you transfer $10K from your bank […]

An Important New Book on Income and Wealth Inequality

I just got an email from LIS (the group that runs the Luxembourg Income Study and Luxembourg Wealth Study) giving notice of a new book: Income Inequality: Economic Disparities and the Middle Class in Affluent Countries Contrary to the title, there’s a whole section on wealth inequality. The book’s 17 chapters by 17 established researchers/research […]

The Appalachia Map, Yet Again

Lots of desperation talk these days by Republicans hoping to win future national elections by increasing their share of the “missing” white vote, while ignoring all those brown people. (Sean Trende’s piece seem to be the epicenter at this moment.) Nate Cone drives a very effective stake through the heart of that zombie ambition here, with […]

Humans’ Comparative Advantage: Wanting Things

Asset Reflux Disease: Explaining Koo to Krugman

Or: Why Banks Aren’t Like People Steve Keen does a good job of addressing Paul Krugman’s befuddlement with Richard Koo’s balance-sheet-based thinking, here, with detailed models showing how funds flow and stocks change over time. I’d like to address it more succinctly and I hope intuitively, by pointing out a simple misunderstanding that Paul shares […]

One Place Where Mankiw Makes Absolutely No Sense at All

In his Defending the One Percent paper, Greg Mankiw is rather grudgingly acknowledging rent-seeking (and -getting) in the financial industry, and the allocation of top talent to that industry. He sez: The last thing we need is for the next Steve Jobs to forgo Silicon Valley in order to join the high-frequency traders on Wall Street. […]

What Caused the (Next) Housing Bubble? (Six Graphs)

Political Calculations gives us this chart of median new home prices versus median incomes over the last 46 years. The rising tip at the upper right (!) is May 2013. What do you think: sustainable? Here’s the zoomed-in version of recent years, from inside the red dashes: As they say, …new homes are, virtually by definition, at the […]
