The US dollar weakened significantly this past week as rising oil prices revealed the vulnerabilities of the US economy. Companies are beginning to struggle and have been forced to come up with more creative ways to deal with the energy crisis. With crude oil prices hitting $135 a barrel and gasoline in many states topping $4 a gallon, US companies are making cuts across the board. Ford Motors Co for example plans on reducing production while American Airlines will be lowering capacity by 15 percent and adding bag charges. According to the futures market, some traders even expect gas prices to hit $7 to $8 a gallon. However the US is not alone in having to deal with the oil crisis which is one of the major reasons why the dollar has weakened. Over the past few weeks, the market had been slowly pricing in a pause from the Federal Reserve. At the same time, there was a growing consensus that other central banks may need to begin or continue to cut interest rates. The surge in oil prices and hawkish comments from the European Central Bank, the Bank of England and the Reserve Bank of Australia dramatically altered the outlook for these central banks. With strict inflation targets, traders came to realize that interest rates for these 3 countries will remain unchanged for the foreseeable future and as a result, currency rates adjusted for these expectations. In the coming week, the vulnerabilities of the US economy may become even more apparent. The US markets are closed for Memorial Day on Monday, but we still have a busy week ahead of us with consumer confidence, new home sales, durable goods, first quarter GDP, personal income, personal spending and Chicago PMI due for release. We expect most of these numbers to be dollar

BY the time Frederick A. O. Schwarz Jr. retired from Cravath, Swain & Moore in 2002, he was financially set. He was already an author, he already had a distinguished track record in public service and philanthropy and, of course, he was the great-grandson of a toy magnate.

So when Fritz Schwarz — the name he greatly prefers — joined the nonprofit Brennan Center for Justice at New York University Law School, he seriously considered volunteering his services. He decided against it, and negotiated a salary, albeit one below what a starting lawyer makes.

He never got a raise, and last year, when the Brennan Center ran into a budget crunch, he gave up his pay. But in principle, if no longer in principal, he thinks the salary made sense. “An organization and a person are simply more committed to each other when the person is paid,” he said.

Clearly, Mr. Schwarz has bought into the concept of paid volunteerism. The phrase may sound oxymoronic, but an ever-growing number of retirees and nonprofit executives say it is an apt description of the way modern retirees view nonprofit work. And while no one has gathered statistics on the tendency, experts say there is a good chance that the automatic link between doing good and working for nothing has been permanently severed.

“People used to say, �?Here I am, what do you need done?’ ” said Deborah Russell, director of work-force issues for AARP. “Today’s retirees say, �?Here’s what I do well, how can you use it, and what will you
