He was awarded the Nobel Prize in 2015 for his work on the analysis of consumption, poverty, and welfare. Deaton and economist Anne Case gained recognition for their research on “deaths of despair” in the United States, highlighting the rising mortality rates among White middle-aged Americans due to suicide, drug overdoses, and alcohol-related deaths. Deaton emphasizes the importance of considering national boundaries and domestic issues when addressing poverty and well-being and discusses the limitations of randomized controlled experiments in economics. He also discusses the significance of household survey data in his research and shares his experience of winning the Nobel Prize.
