...will be good for business, says Krugman.
The truth is that conservatives who predict economic doom if we try to fight climate change are betraying their own principles. They claim to believe that capitalism is infinitely adaptable, that the magic of the marketplace can deal with any problem. But for some reason they insist that cap and trade—a system specifically designed to bring the power of market incentives to bear on environmental problems—can’t work. Well, they’re wrong—again.... Still, should we be starting a project like this when the economy is depressed? Yes, we should—in fact, this is an especially good time to act, because the prospect of climate-change legislation could spur more investment spending.Consider, for example, the case of investment in office buildings. Right now, with vacancy rates soaring and rents plunging, there’s not much reason to start new buildings. But suppose that a corporation that already owns buildings learns that over the next few years there will be growing incentives to make those buildings more energy-efficient. Then it might well decide to start the retrofitting now, when construction workers are easy to find and material prices are low. The same logic would apply to many parts of the economy, so that climate change legislation would probably mean more investment over all. And more investment spending is exactly what the economy needs.
