什么是市场失灵,引起市场失灵的原因主要有哪些?

正确答案及解析

正确答案
解析

市场失灵是指由于外部条件或内部原因导致的市场机制转移资源的能力不足而达不 到帕累托最优状态的现象。

引起市场失灵的原因主要有垄断、外在性、公共物品和不完全信息等。垄断是竞争性经济 不可避免的现象。与竞争性经济相比,垄断厂商为了自身的利润最大化所选择的产量更低、价 格更高,因而导致社会福利受损。外部影响导致社会收益或社会成本与私人收益或成本不相同, 私人单独决策的结果并非是社会所需要的。公共物品通常具有非排他性,因而私人供给不足。 不完全信息使得价格信号不能完全反映实际需求和供给。正因为如此,市场机制会出现失灵。

Two years ago,Rupert Murdoch’s daughter,Elisabeth,spoke of the“unsettling dearth of integrity across so many of our institutions”.Integrity had collapsed,she argued,because of a collective acceptance that the only"sorting mechanism"in society should be profit and the market.But"it's us,human beings,we the people who create the society we want,not profit".

Driving her point home,she continued:“It’s increasingly apparent that the absence of purpose,of a moral language within government,media or business could become one of the most dangerous goals for capitalism and freedom.”This same absence of moral purpose was wounding companies such as News International,she thought,making it more likely that it would lose its way as it had with widespread illegal telephone hacking.

As the hacking trial concludes-finding guilty one ex-editor of the News of the World,Andy Coulson,for conspiring to hack phones,and finding his predecessor,Rebekah Brooks,innocent of the same charge-the wider issue of dearth of integrity still stands.Journalists are known to have hacked the phones of up to 5,500 people.This is hacking on an industrial scale,as was acknowledged by Glenn Mulcaire,the man hired by the News of the World in 2001 to be the point person for phone hacking.Others await trial.This saga still unfolds.

In many respects,the dearth of moral purpose frames not only the fact of such widespread phone hacking but the terms on which the trial took place.One of the astonishing revelations was how little Rebekah Brooks knew of what went on in her newsroom,how little she thought to ask and the fact that she never inquired how the stories arrived.The core of her successful defense was that she knew nothing.

In today’s world,it has become normal that well-paid executives should not be accountable for what happens in the organizations that they run.Perhaps we should not be so surprised.For a generation,the collective doctrine has been that the sorting mechanism of society should be profit.The words that have mattered are efficiency,flexibility,shareholder value,business-friendly,wealth generation,sales,impact and,in newspapers,circulation.Words degraded to the margin have been justice,fairness,tolerance,proportionality and accountability.

The purpose of editing the News of the World was not to promote reader understanding,to be fair in what was written or to betray any common humanity.It was to ruin lives in the quest for circulation and impact.Ms.Brooks may or may not have had suspicions about how her journalists got their stories,but she asked no questions,gave no instructions-nor received traceable,recorded answers.

Which of the following is suggested in the last paragraph?(  )

  • A.The quality of writings is of primary importance
  • B.mmon humanity is central to news reporting
  • C.Moral awareness matters in editing a newspaper
  • D.Journalists need stricter industrial regulations
