[简答题]International investors seem incapable of ending their love affair
with the dollar. America’s economy has slowed sharply this year, yet its
currency has risen to a 15 year high in trade weighted terms. (46) Against
the euro the dollar touched $ 0.88 — 8% higher than in early January and close
to the level at which the European Central Bank and the Federal Reserve jointly
intervened to prop up the European currency last September. Why is the euro
looking sickly
There are plenty of theories. One is that the
markets do not trust the ECB: (47) the euro area economies are not immune to
America’s downturn, yet the central bank still seems more concerned with
fighting inflation than with supporting growth; another more plausible
explanation is that, in an uncertain global economic climate, the dollar has
resumed its traditional role as a safe-haven currency. Most economists
reckon that the euro is undervalued and expect a rebound over the next year. One
of the most optimistic is Goldman Sachs, which is predicting a rate of $1.22 in
12 months.
But an analysis by David Owen, an economist at
Dresdner Kleinwort Wasserstein, gives pause for thought. (48) He has found
that, over the past decade, movements in the real exchange rate of the euro
against the dollar have closely reflected the difference between productivity
growth in the euro area and in America. When productivity growth in America
has been faster than in Europe—as it was in most of the late 1990s—the euro
falls, and vice versa. This is exactly what economic theory would predict:
countries with faster productivity growth in the traded goods sector should see
rising real exchange rates. Mr. Owen uses monthly data for productivity growth
in manufacturing, a good proxy for the traded goods sector. Using annual
productivity data for the whole economy (which are available over a longer
period), the broad relationship between the exchange rate and relative
productivity growth in America and Europe seems to have persisted for most of
the past 30 years.
Mr. Owen reckons that, in the short term,
America’s downturn will reduce the productivity gap between America and the euro
area, and so boost the euro. (49) But in the long term, he expects
productivity growth to remain faster in America—in which case, a sustained rise
in the euro is unlikely over the next few years. Only if the downturn completely
kills the belief in America’s new paradigm, and its productivity growth
plummets, will the euro be able to rebound more permanently.
The strength of the dollar this year does indeed seem to hinge on a
belief among investors that America’s slowdown will be brief, and that in the
longer run America remains the best place in which to invest. (50) But they
may be underestimating the potential for productivity gains in Europe, as the
single currency boosts competition and encourages firms to exploit economies of
scale through mergers and acquisitions. The adoption of more flexible
working practices in many countries should also help to improve
productivity.
Studies in America suggest that the bulk of its
productivity gains from information technology come from the use of it rather
than from its production. So the euro area, too, should start to enjoy
productivity gains over the next decade, as it makes fuller use of it. If you
believe that Europe really is starting to change, buy Euros. If not, stick with
the darling dollar.
[简答题]
"宜家"的供应链运作在全球拥有180家的"宜家"连锁商店，分布在42个国家。2002年它获取了110亿欧元的收入和超过11亿欧元的净利润，成为全球最大的家居商品零售商。它的成功之路，除了具有一整套严格的组织系统外，还有一套周密的管理体系。从产品设计开始，"宜家"就坚持自己设计，并拥有产品专利，具体做法是从100多名设计师所设计的新产品中，进行挑选，选择同样价格的产品中其设计的成本最低的。当产品设计确定之后，设计研发机构将和分布在全球的33个国家设立的40家"宜家"贸易代表处，共同确定哪些供应商可以在成本最低而又保证质量的情况下，生产这些产品。在激烈竞争中得分高的供应商将得到大订单。同时，"宜家"为其所有的供应商设定了不同标准和等级，并经常进行考核。在物流环节上，为保证最低的成本，严格控制物流的每一个环节，如一直推行的"平板包装"，节省了大量的产品粗装成本，达到了降低运输成本和提高效率的目的；又如将枕头里的空气抽掉，以节省大量商品体积等。为了节省运输时间，"宜家"在全球的近20家配送中心与一些中央仓库大多集中在海陆空的交通要道。"宜家"通过科学的计算，决定哪些产品在本地制造销售，哪些出口到海外的商店。因此，"宜家"的整个供应链的运作，从每家商店提供的实时销售记录开始，反馈到产品设计研发机构，再到贸易机构、生产商、物流公司、仓储中心，又转回到商店。
我们从中得到哪些启示？
