STOCKHOLM (Reuters) - British-born economist Angus Deaton won the 2015 economics Nobel Prize for "his analysis of consumption, poverty and welfare", the Royal Swedish Academy of Sciences said on Monday.
The academy said that Deaton's work had been a major influence on policy making, helping for example to determine which social groups are affected by an increase of value-added tax on food.
"To design economic policy that promotes welfare and reduces poverty, we must first understand individual consumption choices," the award-giving body said on announcing the 8 million Swedish crown ($978,000) prize.
"More than anyone else, Angus Deaton has enhanced this understanding," it said.
Deaton also spearheaded the use of household survey data in developing countries, especially data on consumption, to measure living standards and poverty, the academy said.
The economics prize, officially called the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was established in 1968. It was not part of the original group of awards set out in dynamite tycoon Nobel's 1895 will.
