papers include articles in the 1994 and 1997 Economic Journal, the 1996 Journal of Public Economics, the 2001 American Economic Review, the 2002 International Journal of Epidemiology, and the 2004 Journal of Public Economics. According to www.repec.org some of these are among the most-quoted writings in modern economics. A paper in Science, co-authored with Steve Wu, in 2010, showed that across the United States there is a match between subjective well-being scores and objective measures. In 2012, Andrew Oswald published an article in the Proceedings of the National Academy of Sciences of the USA arguing that, like humans, great apes have a tendency to U-shaped wellbeing through life. Oswald has also worked on the beneficial influence of a fruit-and-vegetable diet on happiness and psychological health, in articles in Social Indicators Research in 2013 and the American Journal of Public Health in 2016. Measuring societal achievement Oswald has questioned the dominance of GDP in progress measurement, and said "Feelings data will dominate data collection in our world in the very long run." COVID-19 In April 2020, Oswald released a paper, jointly written with Nattavudh Powdthavee, on the idea that the young cohort of workers could be released first from the coronavirus crisis ‘lockdown’ of 2020. This led to public debate and publicity in newspapers such as the Financial Times. Other work Oswald's other work includes research that finds a U-shape in human well-being through life, on blood pressure and well-being, on happiness and productivity, on antidepressants, and on risk-taking. His recent co-authors include Nick Powdthavee, author of The Happiness Equation, and the Warwick economists Eugenio Proto and Daniel Sgroi. More broadly, earlier journal articles included work on the design of optimal nonlinear taxation in a world in which people care about their relative income (in the 1983 Journal of Public Economics) and on why humans imitate each other (in the 1998 Journal of Public Economics). These articles are rather mathematical. He has also worked with Liam Graham on the theory of hedonic adaptation (in the 2010 Journal of Economic Behavior and Organization); a key idea in their paper is that humans have a pool of psychic resources called by the authors 'hedonic capital'. Media contributions Oswald contributed to the BBC series The Happiness Formula, has written over 200 articles for newspapers and magazines, and given about 1000 broadcast-media interviews around the world. One article that provoked a public debate was his
