[多项选择]It is 15 years since Moises Naim coined the memoraible phrase "corruption eruption". But there is no sign of the eruption dying down. Indeed, there is so much molten lava and sulphurous ash around that some of the world’s biggest companies have been covered in it. Siemens and Daimler have recently been forced to pay gargantuan fines. BHP Billiton has admitted that it may have been involved in bribery. America’s Department of Justice is investigating some 150 companies, targeting oil and drugs firms in particular.
The ethical case against corruption is too obvious to need spelling out. But many companies still believe that, in this respect at least, there is a regrettable tension between the dictates of ethics and the logic of business. Bribery is the price that you must pay to enter some of the world’s most difficult markets (the "when in Rome" argument). Bribery can also speed up the otherwise glacial pace of bureaucracy (the "efficient grease" hypothesis). And why not The chance
A. The likelihood of prosecution is also growing. The Obama administration has revamped the Foreign Corrupt Practices Act (FCP and is using it to pursue corporate malefactors the world over. The Department of Justice is pursuing far more cases than it ever has before. Recent legislation has made senior managers personally liable for corruption on their watch. They risk a spell in prison as well as huge fines. The vagueness of the legislation means that the authorities may prosecute for lavish entertainment as well as more blatant bribes.
