Supporters of the new super systems argue that these mergers will allow for substantial cost reductions and better coordinated service. Any threat of monopoly, they argue, is removed by fierce competition from trucks. But many shippers complain that for heavy bulk commodities traveling long distances, such as coal, chemicals, and grain, trucking is too costly and the railroads therefore have them by the throat.
The vast consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such "captive" shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who fed they are being overcharged have the right to appeal to the federal government's Surface Transportation Board for rate relief, but the process is expensive, time consuming, and will work only in truly extreme eases.
Railroads justify rate discrimination against captive shippers on the grounds that in the long run it reduces everyone's cost. If railroads charged all customers the same average rate, they argue, shippers who have the option of switching to trucks or other forms of transportation would do so, leaving remaining customers to shoulder the cost of keeping up the line. It's theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. "Do we really want railroads to be the arbiters of who wins and who loses in the marketplace"? Asks Martin Bercovici, a Washington lawyer who frequently represents shipper.
Many captive shippers also worry they will soon be tilt with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortunes. Still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to acquire one another, with Wall Street cheering them on. Consider the $10.2 billion bid by Norfolk Southern and CSX to acquire Conrail this year. Conrail's net railway operating income in 1996 was just $427 million, less than half of the carrying costs of the transaction. Who's going to pay for the rest of the bill? Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market.
According to those who support mergers railway monopoly is unlikely because ______.
A．cost reduction is based on competition
B．services call for cross-trade coordination
C．outside competitors will continue to exist
D．shippers will have the railway by the throat
A、species
B、collections
C、/
D、/

Movie directors sometimes shoot two endings to a film, undecided about which to use until the very last minute. In the Casablanca everyone knows, Ingrid Bergman leaves Humphrey Bogart, but in another ending Bogart got the girl.
In some ways, it feels like we're in the middle of a movie made by some deranged(疯狂的) economist, and we don't know yet if we're going to get the happy ending or the sad one. Does the rise of India and other developing countries supercharge(提高) global growth, or will all the new competition pull down wages in the industrialized world? Is this period going to be titled The Bright Dawn or The Big Squeeze?
Certainly for workers in the industrialized world, the latest signs are troubling. Profits seem to be outpacing wages just about everywhere. As a result, from Japan to the U.S. to Europe, labor is getting a smaller share of the economic pie. The numbers are pretty straightforward: In Japan, the share of national income going to workers dropped from 53.1% in 2001 to 51.1% in the year ending with the first quarter of 2005. In the U.S., the employee share of gross domestic income dropped from 58% to 56.8%. In Western Europe, workers' share of national income dropped from 51.7% in 2001 to 50.5% at the end of 2004, before bouncing up a bit in the latest quarter.
An obvious—and pessimistic—explanation for this broad decline is the intensification of global competition, forcing formerly privileged workers in advanced countries to accept a lower standard of living. Harvard economist Richard Freeman has argued that the entry of China, India, and the former Soviet countries into the global economy has effectively doubled the size of the world's workforce. As a result, labor is relatively abundant, capital is relatively scarce, the returns to labor go down, and the returns to capital go up.
"Having twice as many workers and newly the same amount of capital places great pressure on labor markets throughout the world", writes Freeman. That "shifts the balance of power in markets toward capital, as more workers compete for working that capital."
This is the unhappy ending to the global economy story. However, the numbers are also consistent with another, much more upbeat(乐观的)ending. It could be that corporate restructuring efforts in Japan and Europe are finally taking hold, leading to higher profits and faster productivity growth, even as U.S. companies continue their efforts to boost efficiency. And it could be that there's just a lag before the productivity gains get passed on to workers in the form. of higher wages.
So, will we get the happy ending or the sad ending? There's no way of telling yet—but hey, what fun is a movie with a predictable ending?
Similar to the story in the movie Casablanca, the world economy______.
A．is experiencing dramatic changes
B．is set in complicated political factors
C．involves fierce competition between different parties
D．is developing into two possible opposite directions
A、available
B、obtainable
C、possible
D、necessary
