Consider a world in which there are two countries， Guatrarica and Costamala， who share an open border such that labor flows freely between the two countries. Total income (GDP) in each country is equal to the sum of wages and rents to capital owners that accrue from production as in Figure 7-2. Explain the impact on the two countries from a technology shock that increases the marginal product of labor in Costamala:
a.The number of workers in each country.
b.Wages in each country.
c.GDP in each country.
d.Capital rents in each country.
Old volcanic mountains, long and motionless, take up a large part of the island's center, with the highest peak, Cerro de Punta, at 1,338 meters in the Cordillera Central. The mountains are surrounded by a coastal plain with Atlantic shore beaches cooled all year round by trade winds.
The population is 3.8 million, of which about 1.5 million live in San Juan, although about another two million Puerto Ricans live in the USA. (77) The average lifespan is 73.8 years and GDP per capita is US＄12, 212, the highest in Latin America, although not up to the level of the continental USA. The people are largely a mixture of Amerindian, TainoArawak, Spanish and African. Most Puerto Ricans do not speak English and less than 30% speak it well. The people are very friendly and hospitable, but there is law-breaking action linked to drags and unemployment.
It can be learned from the passage that ______ .
A．Puerto Rico belongs to the USA
B．Puerto Rico is part of Spain
C．Puerto Rico is an independent country
D．Puerto Rico has the highest peak in Latin America
Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Three striking facts highlight the dramatic shift in recent years in the relative economic balance of "first-world" and "third-world" economies. Last year, according to the estimates, emerging economies produced slightly more than half of world output measured at purchasing-power parity (等值). Second, they also accounted for more than half of the increase in global GDP in current-dollar terms. And third, perhaps most striking of all, the 32 biggest emerging economies, which we track weekly in The Economist and Economist.com, grew in both 2004 and 2005. Every previous year during the past three decades saw at least one country in recession--if not a deep crisis. Some economies will inevitably stumble over the coming years, but, thanks to sounder policies, most can look forward to rapid long-term growth. The young emerging economies have grown up in more ways than one.
Such happenings are part of the biggest shift in economic strength since the emergence of the United States more than a century ago. As developing countries and the former Soviet block have embraced market-friendly economic reforms and opened their borders to trade and investment, more countries are industrializing than ever before--and more quickly. During their industrial revolutions America and Britain took 50 years to double their real incomes per head; today China is achieving that in a single decade. In an open world, it is much easier to catch up by adopting advanced countries' technology than it is to be an economic leader that has to invent new technologies in order to keep growing. The shift in economic power towards emerging economies is therefore likely to continue. This is returning the world to the sort of state that endured throughout most of its history. People forget that, until the late 19th century, China and India were the world's two biggest economies and today's "emerging economies" accounted for the bulk of world production.
Many bosses, workers and politicians in the rich world fear that the success of these newcomers will be at their own expense. But rich countries will gain more than they lose from the enrichment of others. Fears that the third world will steal rich-world output and jobs are based on the old fallacy that an increase in one country's output must be at the expense of another's. But more exports give developing countries more money to spend on imports--mainly from developed economies. Faster growth in poor countries is therefore more likely to increase the output of their richer counterparts than to reduce it. The emerging economies are helping to lift world GDP growth at the very time when the rich world's ageing populations would otherwise cause growth to slow.
From the first paragraph we can learn that ______.
A．there is a dramatic shift in recent years in the world economy
B．emerging economies produced nearly half of world output
C．there are 32 emerging economies in "third-world"
D．the young emerging economies have developed rapidly in recent years
Judging by prices in futures markets, investors are betting that short-term interest rates could start rising as early as May, and will be 1.25 percentage points higher by the end of the year. That may be excessive. Economists at Goldman Sachs, who long argued that the central bank would do nothing this year, now expect short-term rates to go up only 0.75% this year, starting in June. But virtually everyone reckons some Fed tightening is in the future.
The reason？ After an unprecedented 11 rate-cuts in 2001, short-term interest rates are abnormally low. As the signs of robust recovery multiply, analysts expect the Fed to take back some of the rate-cuts it used as an "insurance policy" after the September 11th terrorist attack. But higher rates could still be further off, particularly if the recovery proves less robust than many hope. The manufacturing sector is growing after 18 months of decline. The most optimistic Wall Streeters now expect GDP to have expanded by between 5% and 6% on an annual basis in the first quarter.
But one strong quarter does not imply a sustainable recovery. In the short term, the bounce-back is being driven by a dramatic restocking of inventories. But it can be sustained only if corporate investment recovers and consumer spending stays buoyant. And since consumer spending held up so well during the "recession" it is unlikely to jump now.
These uncertainties alone suggest the central bank will be cautious about raising interest rates. That caution is all the more necessary given the lack of inflationary pressure. Although America's consumer prices have stopped falling on a monthly basis, the latest figures show few signs of nascent price pressure. Indeed, given the huge pressure on corporate profits, the Federal Reserve might be happy to see consumer prices rise slightly. In short, while Wall Street frets about when and how much interest rates will go up. The answer may well be not soon and not much.
Some people expected short-term interest rates to jump soon because they ______.
A．strongly believed in economic recovery.
B．took for granted economic expansion.
C．were cautious in their excessive investment.
D．had doubts about the effects of price pressure.
