Krugman - a professor at Princeton University, the most recent winner of the Nobel Prize in economics, and a columnist for the New York Times - talks about the global financial meltdown: what surprises him, what scares him, and what he'd do to ensure a recovery if he were calling all the shots.

Can the U.S. economy grow much faster than the two-point-something percent it has in recent years? Standard economic analysis suggests that it cannot. But many influential business leaders and journalists--and even a few economists--have embraced a radical economic theory that argues that the old speed limits to growth are obsolete. According to this so-called new paradigm, rapid technological change means that the economy can grow much faster than it used to; global competition means that a booming economy will not produce high inflation. Many people in the business community take the new doctrine very seriously, notes MIT economist Paul Krugman. Unfortunately, he says, it is riddled with gaping conceptual and empirical holes. Krugman lays out in clear terms the macroeconomic principles that explain how markets interact and why there are limits on growth. We would all like the U.S. economy to grow faster than it has, says Krugman, but all the evidence suggests that it cannot.

Should politicians turn to business leaders for advice in formulating economic policy? Not according to economist Paul Krugman, who argues that executives' advice is often disastrously misguided. Business leaders who have been promoted to economic advisers are no more likely to be great economists than are military experts. People who have mastered the complexities of running a multibillion-dollar enterprise may think they can make pronouncements whenever the subject is money, but before they can offer sound economic advice, they must master a new vocabulary and a new set of concepts. In short, they must go back to school.

In this article, Stanford economist Paul Krugman argues that fears about the impact of Third World competition are questionable in theory and flatly rejected by the data. After examining the consequences of isolated productivity improvements in three increasingly realistic economic models, Krugman concludes that an increase in Third World labor productivity means an increase in world output. And an increase in world output shows up in higher wages for Third World workers, not in decreased living standards for the First World. Yet if the West responds to the widespread fears about Third World economic success by erecting import barriers, the effects could be disastrous--dashing any hope of a decent living standard for hundreds of millions of people throughout the developing world.
