Corzine’s Downfall

The collapse this week of the broker-dealer MF Global and the due punishment of its chief executive Jon Corzine, who resigned Friday, have been and will be put to many political and rhetorical purposes. MF Global’s bankruptcy has been called, possibly, the first domino in a potential collapse of the European banking system; in this rendering, it’s a rough analog to the failure, in the spring of 2008, of Bear Srearns, which warned the chaos of autumn. It might well be cast as a stimulus for more government regulation, or smarter regulation; to some, it might even be a case study in overregulation. Every rationale for regulation seems to contain, as yang to its yin, an argument that regulation is actually to blame.
Corzine’s downfall is an update on Icarus, all illustration of arrogance. It reminds us that leverage kills, that it is dangerous to pick up nickels in front of a steamroller, that risk is risky, that pigs get fat while hogs get slaughtered. It complicates the Democrats’ hopes of controlling anti-Wall Street fervor in the Presidential election, because Corzine has been one of Barack Obama’s most generous supporters-a possible future Treasury Secretary. The Republicans will not soon let this one go.
It certainly further stains the reputation of Goldman Sachs. Corzine, a former C.E.O. of Goldman, took over a company partially owned by the firm of another ex-Goldmanite, Christopher Flowers, and managed, in a year and a half, to destroy it, in part while resisting oversight from a government regulator. That regulator comes from the Commodity Futures Trading Commission, whose chairman, Gary Gensle, is also a Goldman alumnus.
It further damages the perception, or myth, that a becoming-a-partner at Goldman Sachs indicates brilliance, or insures success or a lifetime inclusion in the vampire-squid-piracy, although you can find whisperings of a conspiracy theory that Goldman planted Corzine at MF Global in order to destroy it—a notion that is almost as deceiving as it is ridiculous.
Corzane’s collapse is also an occasion for taking-pleasure-in-others’-suffering. It is an occasion for those among Occupy Wall Street’s 99 per cent, who’d be ready to pitchfork him to pieces. It is also an occasion for the tiny cowering minority, who may resent Goldman for its perceived arrogance or cunning, or who may question the conceited folly and civic harm of Corzine’s spending over a hundred million of his own money to get elected to public office. The sentiment, among his peers, was that Corzine wasn’t so great a trader to begin with. And the sentiment was also that in the years since he had left Goldman, his skills, such as they were, had got rusty or outdated.
It is ironic that Corzine blundered by, and is being criticized for, among other things, betting too unbalancedly on Europe. That is, MF Global was banking on the hope that Portugal, Ireland, Italy, and Greece (whose bonds are collectively known as PIIGS) would not default on their debts by the end of the year. It might have turned out to be a good bet, were it not for the fact that it was made sneakily with money that was borrowed and perhaps even effectively stolen-or for the fact that he basically bet the firm, and the farm. Goldman Sachs, meanwhile, has been criticized, since the housing meltdown of 2008, for having profited from bets against the housing market—for shorting crappy derivatives based on mortgages. That was a good bet, except that Goldman made it while dumping those crappy derivatives on its unwitting clients.

The underlined expression in the 2nd paragraph indicates that Corzine is too ______.
A. cynicalB. greedy
C. arrogant D. ambitious

简述对外贸易国别统计原则中的产消国原则。

A公司是一家生产饮料的企业，在市场中颇有知名度。其生产的B款饮料，市场占有率达．30%。近年来，另一家公司推出C款饮料，其质量不比B款饮料差，每瓶饮料价格却比B款饮料低一元。
在内部研究对策的时候，A公司的市场营销人员提出，通常情况下，公司有三条对策可选：其一，降价一元，以保住市场占有率；其二，维持原价，通过增加广告投入和加强营业推广。(如有奖销售等)活动来与竞争对手竞争；其三，维持原价，听任其市场占有率降低。A公司总经理对以上对策都不满意，理由很简单，因为无论采取以上哪种策略，A公司似乎都会在竞争中处于不利地位。于是，A公司聘请一家市场咨询专业公司提供支持，期待他们提出更好的对策。
咨询公司的市场营销专家们经过深思熟虑后，提出了让竞争对手意想不到的第四种策略：将B款饮料的价格再提高一元、同时推出一种与竞争对手的C款饮料价格一样的D款饮料和另一种价格更低的E款饮料。这一策略，一方面提高了B款饮料在消费者心目中的地位，同时使竞争对手的产品沦为一种普通品牌的产品。据统计，A公司采取此策略后，A公司的B款饮料销量不降反增，D款和E款两款饮料也成功入市，分得一定的市场份额。由此，A公司在竞争中出奇制胜，而且利润大增。

A公司采用的定价策略是( )。

A．成本导向定价

B．心理定价

C．声望定价

D．整数定价
