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...

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...

Unlike oil and coal, which are compressed forms of energy, renewable energy requires unusually large land areas. This article calculates the consequences of a switch to hydrogen-cell vehicles powered by electricity from wind turbines. It then re-does the calculation for three other green energy...

This paper shows that macroeconomic movements have strong effects on the happiness of nations. First, we find that there are clear microeconomic patterns in the psychological well-being levels of a quarter of a million randomly sampled Europeans and Americans from the 1970's to the 1990's....

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...

One of the famous questions in social science is whether money makes people happy. We offer new evidence by using longitudinal data on a random sample of Britons who receive medium-sized lottery wins of between £1000 and £120,000 (that is, up to approximately U.S. $200,000). When compared to...

This paper proposes a new way to think about happiness. It distinguishes between stocks and flows. Central to the analysis is a concept we call ‘hedonic capital’. The paper sets out a model of the dynamics of wellbeing in which bad life-shocks are smoothed by the drawing down of hedonic...

It has been known for centuries that the rich and famous have longer lives than the poor and ordinary. Causality, however, remains trenchantly debated. The ideal experiment would be one in which status and money could somehow be dropped upon a sub-sample of individuals while those in a control...

Journalists and others have asked me whether the favourable RAE 2008 results for UK economics are believable. This is a fair question. It also opens up a broader and more important one: how can we design a bibliometric method to assess the quality (rather than merely quantity) of a nation’s...

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...
