CAMBRIDGE – The world's major central banks are currently obsessed with the goal of raising their national inflation rates to their common target of about 2% per year. This is true for the United States, where the annual inflation rate was -0.1% over the past 12 months; for the United Kingdom, where the most recent data show 0.3% price growth; and for the eurozone, where consumer prices fell 0.6%. But is this a real problem?

"There is no easy answer to this problem. But before rushing to impose tariffs, it is important to remember that cap-and-trade policies would not be the only government source of differences in competitiveness. Better roads, ports, and even schools all contribute to a country`s competitiveness."

"The Obama administration and congressional Democrats have proposed a major cap-and-trade system aimed at reducing carbon dioxide emissions. Scientists agree that CO2 emissions around the world could lead to rising temperatures with serious long-term environmental consequences. But that is not a reason to enact a U.S. cap-and-trade system until there is a global agreement on CO2 reduction. The proposed legislation would have a trivially small effect on global warming while imposing substantial costs on all American households. And to get political support in key states, the legislation would abandon the auctioning of permits in favor of giving permits to selected corporations."
