Friedrich Hayek is not an important figure in the history of macroeconomics.

We should try to create the society each of us would want if we didn't know in advance who we'd be.

Simple doesn't mean stupid. Thinking that it does, does.

Governments do not necessarily act in the national interest, especially when making detailed microeconomic interventions. Instead, they are influenced by interest group pressures. The kinds of interventions that new trade theory suggests can raise national income will typically raise the welfare of small, fortunate groups by large amounts, while imposing costs on larger, more diffuse groups.

I've always believed that a speculative bubble need not lead to a recession, as long as interest rates are cut quickly enough to stimulate alternative investments. But I had to face the fact that speculative bubbles usually are followed by recessions. My excuse has been that this was because the policy makers moved too slowly - that central banks were typically too slow to cut interest rates in the face of a burst bubble, giving the downturn time to build up a lot of momentum.

Now, it’s true that some of the protesters are oddly dressed or have silly-sounding slogans, which is inevitable given the open character of the events. But so what? I, at least, am a lot more offended by the sight of exquisitely tailored plutocrats, who owe their continued wealth to government guarantees, whining that President Obama has said mean things about them than I am by the sight of ragtag young people denouncing consumerism.

It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phoney numbers about jobs created or lost.
