Humans run on a fuel called food. Yet economists and other social scientists rarely study what people eat. We provide simple evidence consistent with the existence of a link between the consumption of fruit and vegetables and high well-being. In cross-sectional data, happiness and mental health...

We present evidence that psychological well-being is U-shaped through life. A difficulty with research on this issue is that there are likely to be omitted cohort effects (earlier generations may have been born in, say, particularly good or bad times). First, using data on 500,000 randomly...

A modern statistical literature argues that countries such as Denmark are particularly happy while nations like East Germany are not. Are such claims credible? The paper explores this by building on two ideas. The first is that psychological well-being and high blood-pressure are thought by...

This paper is a continuation of results in Blanchflower and Oswald (2008). It provides new evidence that well-being follows a curve through life. We use data on half a million randomly sampled individuals across eight major European nations. Importantly, we show that in this set of countries...

In surveys of well-being, countries such as Denmark and the Netherlands emerge as particularly happy while nations like Germany and Italy report lower levels of happiness. But are these kinds of findings credible? This paper provides some evidence that the answer is yes. Using data on 16...

This paper estimates micro-econometric happiness equations for the United States and Great Britain. Reported levels of wellbeing have declined over the last quarter of a century in the US; life satisfaction has run approximately flat through time in Britain. These findings are consistent with...

There is a large amount of cross-sectional evidence for a midlife low in the life cycle of human happiness and well-being (a ‘U shape’). Yet no genuinely longitudinal inquiry has uncovered evidence for a U-shaped pattern. Thus some researchers believe the U is a statistical artefact. We...

This paper examines a famous puzzle in social science. Why do some nations report such high happiness? Denmark, for instance, regularly tops the league table of rich nations’ well-being; Great Britain and the US enter further down; France and Italy do relatively poorly. Yet the explanation for...

Many environmentalists have not yet discovered and understood the value to them of a new research literature. That literature is the economics of happiness. It offers a potentially important tool for future policy debate. In particular, this literature offers a defensible way to calculate the...
