We perform an experiment designed to assess the accuracy of beliefs about distributions. The beliefs relate to behavior (mobile phone purchasing decisions, hypothetical restaurant choices), attitudes (happiness, politics) and observable characteristics (height, weight) and are typically formed...

Little is known by economists about how emotions affect productivity. To make persuasive progress, some way has to be found to assign people exogenously to different feelings. We design a randomized trial. In it, some subjects have their happiness levels increased, while others in a control...

We live in a high-divorce age. Parents worry about the possibility of negative effects upon their children. This paper tests whether recent parental-divorce has deleterious consequences for grown children. Under controlled conditions, it measures students’ happiness with life, and their...

Some firms say they care about the happiness and ‘well-being’ of their employees. But are such claims hype? Or might they be scientific good sense? This study provides evidence that happiness makes people more productive. First, we examine fundamental real-world shocks (bereavement and...

In an incentivized experiment we identify a powerful and ubiquitous bias: individuals regard their own characteristics and choices as more common than is the case. We establish this \false consensus" bias in terms of happiness, political stance, mobile phone brand and on the attitude to...

Cognitive biases have been a recognised feature of research into human behaviour...

Economists and behavioural scientists are beginning to make extensive use of measures of subjective well-being, and such data are potentially of value to policy-makers. A particularly famous difficulty is that of “priming”: if the order or nature of survey questions changes people’s likely...

We present the first attempt to construct a long-run historical measure of subjective wellbeing using language corpora derived from millions of digitized books. While existing measures of subjective wellbeing go back to at most the 1970s, we can go back at least 200 years further using our...

The paper provides evidence that happiness raises productivity. In Experiment 1, a randomized trial is designed. Some subjects have their happiness levels increased, while those in a control group do not. Treated subjects have 12% greater productivity in a paid piece-rate Niederle-Vesterlund...
