November 2017Depression through the Lens of Economics: A Research Agenda
with Johannes Haushofer
in The Economics of Poverty Traps, Christopher B. Barrett, Michael R. Carter, and Jean-Paul Chavas, editors
Major depressive disorder (MDD) is one of the most prevalent mental illnesses worldwide. Existing evidence suggests that it has both economic causes and consequences, such as unemployment. However, depression has not received significant attention in the economics literature, and existing work is almost entirely empirical. We see great potential for traditional, theoretical economic analysis to both develop new insights about depression, and to form new connections to other areas of economics. In this paper, we begin with an overview of the canonical symptoms of depression, identifying a set of key facts that lend themselves well to economic analysis. We illustrate these facts with descriptive analysis of data from Indonesia. We then discuss what we see as fruitful avenues for new theoreti...
June 2017Measuring and Bounding Experimenter Demand
with Johannes Haushofer, Christopher Roth: w23470
We propose a technique for assessing robustness of behavioral measures and treatment effects to experimenter demand effects. The premise is that by deliberately inducing demand in a structured way we can measure its influence and construct plausible bounds on demand-free behavior. We provide formal restrictions on choice that validate our method, and a Bayesian model that microfounds them. Seven pre-registered experiments with eleven canonical laboratory games and around 19,000 participants demonstrate the technique. We also illustrate how demand sensitivity varies by task, participant pool, gender, real versus hypothetical incentives, and participant attentiveness, and provide both reduced-form and structural analyses of demand effects.
December 2016Depression for Economists
with Johannes Haushofer: w22973
Major depressive disorder (MDD) is one of the most prevalent mental illnesses worldwide. Existing evidence suggests that it has both economic causes and consequences, such as unemployment. However, depression has not received significant attention in the economics literature. In this paper, we present a simple model which predicts the core symptoms of depression from economic primitives, i.e. beliefs. Specifically, we show that when exogenous shocks cause an agent to have pessimistic beliefs about the returns to her effort, this agent will exhibit depressive symptoms such undereating or overeating, insomnia or hypersomnia, and a decrease in labor supply. When these effects are strong enough, they can generate a poverty trap. We present descriptive evidence that illustrates the predicted re...
