But there was a time when Les Angeles was nothing more than a tiny Indian village. The Spanish expedition searching for Monterey Bay camped there the night of August 1,1769. Twelve years later, other Spaniards started a settlement at the village, which remained unchanged for decades. Yankee sea traders used the settlement as a port, and the California gold rush brought some new economic life to the village, but the town remained quite small. It was not until the completion of the transcontinental railroads in 1869, and the discovery of oil in the 1890s, that the population began to grow. Later, during the two world wars, Los Angeles experienced move growth, in part because of the new airplane industry. At about the same time, the arrival of two New York motion picture producers in search of sunny weather marked the beginning of an entertainment industry that has become a multibillion-dollar industry today. In just the past 100 years, this tiny sea village has grown into the sprawling metropolis that we know today. (27) A．European expeditions in the 1700s. B．Famous sites in Los Angeles.

The performance of the US labour market in the late 1990s is as much a feature of the puzzlingly benign so-called New Economy. For the past four years the US has enjoyed an average annual growth rate of 4 percent— up from an average of about 3 percent in the previous decade. Productivity improvements account for about two-thirds of that elevated output, as workers have increased their output per hour. The rest has come from a rapid increase in the total number of workers, what economists call labour inputs. There has been a surge in new jobs—7m in the last three years—that has pushed the unemployment rate down into the uncharted territory of barely 4 percent. Recent economic history suggests that, whenever unemployment has gone this low, the scramble for workers becomes so difficult that wages are rapidly bid up, and an inflationary spiral follows. But in the US in the past five years, wage growth has been muted. In the last year, total employee compensation in the private sector rose by just 3.3 percent, almost unchanged on the figure three years ago, when the unemployment rate was 5.4 percent. "In some ways it's a bigger puzzle than the productivity puzzle," says Paul Krugman, professor of economics at the Massachusetts Institute of Technology. "How can we have such a low unemployment rate without an explosion of wages？" A number of factors appear to have contributed. In their search for workers to fill positions, companies have reached out to places they have not looked at in the past. As a result, more people are working than ever. The proportion of the population in employment reached a record high this year of more than 64 percent. This expanded labour supply helps explain why companies have kept the lid on pay over the last few years. The availability of new sources of labour—women, retirees, college students among them—means companies may not have to give big pay rises to hire new workers. It also helps explain why the benefits of the New Economy are not always widely felt—more people seem to be working longer hours than ever. But an expanded labour supply can only explain part of what has changed in the US in recent years. After all, unemployment—the proportion of the labour force out of work—has still declined, indicating that companies have drawn new workers not just from the pool of those not previously in the labour force, but also from the unemployed. And yet still wage costs have remained muted. One possible explanation is that companies have become more flexible in how they pay. "At Newfield, we use a much broader variety of means to reward workers, including performance related pay, year-end bonuses, and extended contracts," says Mr. Ostop. Why does Connecticut have the tightest labour market in the U. S. ？

An official report concluding that the criminal justice system is failing has added to the government's problems. The Audit Commission, the government's watchdog, says that the police too often charge suspects with the wrong offences, use inaccurate computerized information and face serious inefficiencies in the forensic science (the use of scientific methods by the police) service. Court delays alone are costing taxpayers￡80m ($120m) a year. The result is that few criminals are brought to justice and even fewer convicted. Only 6% of the more than 5m offences recorded by the police last year resulted in a conviction. Hardly surprising, then, that more than half the public believes that the criminal justice system is ineffective. The main purpose of the White Paper published last year is to address concerns that the procedures of the court are weighted too heavily against the prosecution. It includes many sensible and uncontroversial proposals. It asks for more support for witnesses, many of whom are frightened of testifying. A survey of one London court found that, of 140 witnesses called in a two-week period, only 19 actually turned up. Making juries more representative must also make sense. Getting off jury service is too easy. In some London courts, two-thirds of those called for jury service fail to turn up. As a result, juries are often composed of housewives, the unemployed and the retired. The White Paper recommends a check on professionals' getting off service, who can excuse themselves by saying their work is too important, and proposes penalties for those who fail to comply. Other proposed reforms will be more controversial. At present, no defendant can be tried for the same offence twice even if compelling new evidence emerges. The government's plan to scrap that law will be resisted by civil liberties campaigners, as will the proposal that previous convictions should be disclosed in open court if they are relevant to the case being heard. Whether or not such proposals make it into law, the White Paper did not do much to address public concerns. The reason why 94% of crimes do not result in a conviction is that three-quarters of them are not cleared up, and so nobody is charged. That is the fault of the police, not the courts; and that is the part of the criminal justice system that the government needs to focus on if it is to make a difference.
