　　The winner of the 2015Nobel Prize in Economic Sciences studies personal consumption（消费）．He also has explored how spending can affect both living conditions and poverty．

　　The Royal Swedish Academy of Sciences is presenting the Economics Prize to Professor Angus Deaton of Princeton University in New Jersey．The Nobel committee says his research has mainly dealt with three questions：How do consumers distribute their spending among different goods？How much of society's wealth is spent and how much is saved？And，how do we best measure and study wellbeing and poverty？

　　Mr．Deaton used household surveys to collect detailed information about how families spend their money．For example，in one study，the Princeton professor examined the relationship between poverty and the amount of calories in the food people ate．

　　The Nobel committee said Mr．Deaton's research has shown how the clever use of household data can shed light on issues such as the relationship between income and calorie intake，and the degree of sexual discrimination（歧视）with the family．

　　The Princeton professor was asked why he paid so much attention to household information．Mr．Deaton said that his studies were mainly about people and their behavior．

　　The Nobel committee also，praised Mr．Deaton's work because it used detailed information about real people，not theoretical ideas．Subjects of his research have included happiness，well-being and aging．

　　At a press conference this week，the Nobel Prize winner said he was pleased that his work had been recognized．He told reporters he believed poverty would decrease．"I think we've had a remarkable decrease for the past 20to 30years．I do expect that to continue，"he said．

　　Mr．Deaton is a citizen of both the United States and Britain．He was born in Scotland．He has served as a Professor of Economics and International Affairs at Princeton since 1983．The Economics Prize has been offered by Sweden's central bank in m
