Quote 17: Dani Rodrik on the problem with economist

Dani Rodrik’s blog can be found here. I found this quote insightful:

“The problem wasn’t with the economics but with the economists.” Theories and models are tools, but “we have fixated on one of the possible hundreds of models and elevated that above the others,” he said, referring to free market theory. “We form a narrative of the moment, which fits the zeitgeist.”

From the New York times (ht The Big Picture).

Like we have said a million times – the economic method is awesome for framing issues. But picking a model (which involves picking a set of value judgments) is not necessarily our strong point.

Previously, I have felt that economists could focus on setting up the framework and letting other people throw in the value judgments – but this process has not described the way economists have acted. As a result, it also shouldn’t describe what people judge economists on.

The economic method is great for making value judgments transparent – but it appears (some) economists seem more interested in clouding their models for political purposes than making full use of the framework. This is the message I gained from Dani Rodrik’s quote 🙂

Quote 14: Milton Friedman on policy prescriptions

This was from Greg Mankiw’s blog:

The role of the economist in discussions of public policy seems to me to be to prescribe what should be done in light of what can be done, politics aside, and not to predict what is “politically feasible” and then to recommend it.

If you ever get annoyed with the fact that much of what economists say is politically infeasible this is the quote that explains how we feel. When giving policy we see ourselves as describing the process “removed” from the institution of government – in many ways economists have an idealistic view of government as a body that actually functions in the interest of society.

The fact that a policy isn’t “politically feasible” doesn’t stop it being optimal in the face of more natural constraints.

Unhappy the land that is in need of heroes

Ed Prescott has written some pretty brainy stuff in his time. I’m particularly a fan of his work on dynamic inconsistency in economics with Finn Kydland. But, here we see why you should not make heroes of people. Read more

Quote 13) John Maynard Keynes on stock fluctuations

John Maynard Keynes again 😉

The market can stay irrational longer than you can stay solvent.

An apt quote given current extreme uncertainty, and the talk about stock being “cheap”.

Quote 12: Michael Lewis on incentives in Wall Street

Michael Lewis:

He thought the cause of the financial crisis was “simple. Greed on both sides—greed of investors and the greed of the bankers.” I thought it was more complicated. Greed on Wall Street was a given—almost an obligation. The problem was the system of incentives that channeled the greed.

Found in the December 2008 portfolio magazine (ht Robbie Allan).

Quote: 11) Thomas Sowell on economics and politics

Although I don’t agree with all Thomas Sowell has to say, this quote is brilliant:

The first lesson of economics is scarcity: there is never enough of anything to fully satisfy all those who want it. The first lesson of politics is to disregard the first lesson of economics

I think this quote is apt following an election. All political parties prefer to ignore trade-offs – they just focus is ability in different policy areas 😛
