Before going to Europe on business, a woman drove her new Rolls-Royce to a downtown bank in New York City and went in to ask for a loan of $5,000. The bank officer said the bank would need some kind of security for the loan, so the women handed over the keys to her Rolls-Royce. The car was parked on the street in front of the bank. The bank agreed to accept the car as collateral for the loan. The bank's president and its officers all enjoyed a good laugh at the woman for using a $250,000 Rolls-Royce as collateral against a $5,000 loan. An employee of the bank then proceeded to drive the Rolls into the bank's underground garage and parked it there. Two weeks later, the woman walked through the bank's doors and asked to settle up her loan and get her car back. "That will be $5,000 in principal, and $20.30 in interest," the loan officer said. The woman wrote out a check and started to walk away. "Wait, Miss," the loan officer said, "We're very happy to have had your business, and this transaction has worked out very nicely, but we are a little puzzled. While you were away, we checked you out and found that you are a multi-millionaire.

Price rises but inflation stays low. 1. Everybody in Britain is talking about falling prices though they know inflation is high. T F 2. Professor Brown found it easy to explain the difficult economic issue. T F 3. Chinese-made products have made Britain poorer. T F 4. In the past decade the CPI in Britain has increased only modestly. T F 5. The low inflation has resulted from higher prices for some goods and lower prices for mass-produced Chinese goods. T F Petrol, up. Eating out, up. School fees, up. Everyone in Britain seems to be talking about price rises, but why then is inflation still so low?
Professor Brown gave the seemingly difficult economic issue a simple answer: It is the low-priced "Made-in-China" products that help keep inflation under control. In his presentation at an economic forum, Brown reminded the price-sensitive Britons that Chinese-made commodities have not only helped bring down the inflation figures, but also made the already rich countries like Britain richer. Consider the following figures. Over the past 10 years, the total cost of living in Britain, as measured by the official consumer price index, has risen by just 14 percent. But that very modest average increase has included high inflation in some categories: school fees, for example, are up 62 percent, hairdressing up 58 percent, holidays up 52 percent, and eating out up 33 percent on average, with top London restaurant prices showing much faster growth. Why then has the total cost of living remained so stable? The answer to the question, the professor said, is not just interesting in its own right, but tells Britons a surprising amount about what is happening today not only in Britain but in the world economy as a whole. Because the prices of mass-produced goods have been plunging: clothes prices down by 42 percent in a decade, shoes by 31 percent and consumer electronics by 63 percent. Professor Brown said that this relates to China's entry into the global economy. By becoming the workshop of the world, China has pushed down the prices of all mass-produced goods.
