We investigate the impact of short-term weather and long-term climate on self-reported life satisfaction using panel data. We find robust evidence that day-to-day weather variation impacts life satisfaction by a similar magnitude to acquiring a mild disability. Utilizing two sources of variation...

The underlying motivations for envy or related social preferences and their impact on agricultural innovations are examined by combining data from money burning experimental game and household survey from Ethiopia.  In the first stage of the money burning experimental game, income inequality is...

Using data from experimental games and household survey from 1,200 married couples in three sites in Ethiopia, this paper uses different versions of a voluntary contribution mechanism to test for household efficiency.  The experimental and econometric analyses provide many interesting results...

Using data from a field experiment conducted in seventy Colombian municipalities, we investigate who pools risk with whom when risk pooling arrangements are not formally enforced.  We explore the roles played by risk attitudes and network connections both theoretically and empirically.  We...

Economists have traditionally assumed that individual behavior is motivated exclusively by extrinsic incentives.  Social physchologists, in contrast, stress that intrinsic motivations are also important.  In recent work, economic theorists have started to build psychological factors, like...

This paper describes and analyzes the results of a unique field experiment especially designed to test the effects of the level of commitment and information available to individuals when sharing risk.  We find that limiting exogenously provided commitment is associated with less risk sharing,...

Standard models of investment predict that credit-constrained firms should grow rapidly when given additional capital, and that how this capital is provided should not affect decisions to invest in the business or consume the capital.  We randomly gave cash and in-kind grants to male- and...

When members of a committee have incentives to agree with each other, they over-weight public information: this can generate status quo bias.  We test this hypothesis using a novel field experiment -  a large debate tournament with random assignment of judges to committees.  To analyse our...

This paper investigates whether expectations of trustworthiness and resulting acts of trust accord with an objective model of trustworthiness or are biased. Combining experimental and survey data, I find that Ghanaian workers appropriately take account of the religiousness of trustees, but...

This paper presents rigorous and direct tests of two assumptions relating to limited commitment and asymmetric information that underpin current models of risk pooling. A specially designed economic experiment involving 678 subjects across 23 Zimbabwean villages is used to solve the problems of...
