Just outside the northern Italian town of Bra, there rises a church tower with a clock that is a half hour slow. Though not far from the industrial city of Turin, Bra smells of roses, and leisure(悠闲) is the law. It is both the home of an international movement that promotes slow food and one of Italian cities that have joined the slow cities. In Bra, population 27,866, the town fathers have declared that all small food shops be closed every Thursday and Sunday. They forbid cars in the town square. All fruits and vegetables served in local schools must be organic(有机的). And as the movement goes well, the slow concept gradually spreads across Europe.

The argument for a Slow Europe is not only that it is good, but also that it can work. The Slow City Movement, which started in 1999, has improved local economies(经济) by promoting local goods and tourism. Young Italians are moving from larger cities to Bra, where unemployment is only 5 percent, about half the nationwide rate. Slow food and wine festivals draw thousands of tourists every year. Shops are doing well, many with sales rising at a rate of 15% per year. “This is our answer to the world.” says Paolo Samrnini, the founder of Slow Cities.

France is in favor of slow economics. Most outsiders have long been doubtful of the French model: short hours and long vacations. Yet the French are more productive than those in the United States and Britain, and have been for years.

The mystery of French productivity has risen an Europewide debate about the advantages of working more slowly.
