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.

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.

The fact is that the two years or so after 9/11 were a terrible time in America – a time of political exploitation and intimidation, culminating in the deliberate misleading of the nation into the invasion of Iraq. It’s probably worth pointing out that I’m not saying anything now that I wasn’t saying in real time back then, when Bush had a sky-high approval rating and any criticism was denounced as treason. And there’s nothing I’ve done in my life of which I’m more proud.

The economic expansion that began in 2001, while it has been great for corporate profits, has yet to produce any significant gains for ordinary working Americans. And now it looks as if it never will.

The Obama campaign seems dangerously close to becoming a cult of personality.

Some years down the pike, we're going to get the real solution, which is going to be a combination of death panels and sales taxes. It's going to be that we're actually going to take Medicare under control, and we're going to have to get some additional revenue, probably from a VAT. But it's not going to happen now.

Every once in a while I feel despair over the fate of the planet. If you’ve been following climate science, you know what I mean: the sense that we’re hurtling toward catastrophe but nobody wants to hear about it or do anything to avert it.
