We provide quasi-experimental estimates of the impact social media on mental health by leveraging a unique natural experiment: staggered introduction Facebook across US colleges. Our analysis couples data student around years Facebook’s expansion with generalized difference-in-differences empirical strategy. find that rollout at college had negative health. It also increased likelihood which st...

Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people's emotions over time predicts changes risk attitudes. Using a large-panel dataset, identify happiness, anger, and fear as significant correlates of within-person Robustness checks indicate limited role alternat...

This paper demonstrates the important link between the incomes and wealth of pensioners and their working-life earnings levels. It uses the combination of detailed income and asset information and working-life history information available in the British Household Panel Survey. The proportionality predicted by a simple “stripped down” form of the life-cycle model is supported for pensioner coup...

We study a simple savings scheme that allows workers to defer receipt of part their wages for three months at zero interest. The significantly increases during the deferral period, leading higher postdisbursement spending on lumpy goods. Two years later, after two additional rounds scheme, we find treated have made permanent improvements homes. popularity implies lack good alternative options. ...

This paper is concerned with learning decision-makers’ preferences using data on observed choices from a finite set of risky alternatives. We propose discrete choice model unobserved heterogeneity in consideration sets and standard risk aversion. obtain sufficient conditions for the model’s semi-nonparametric point identification, including cases where depends some exogenous variables. Our meth...

We study two-player games where one-sided asymmetric information can lead to either adverse or advantageous selection. contrast behavior in these with settings both players are uninformed. find stark differences, suggesting that subjects do account for endogenous selection effects. Removing strategic uncertainty increases the fraction of who Subjects respond more than Using additional treatment...

We provide experimental evidence on coordination within large groups that could proxy the atomistic nature of real-world markets. use a bank run game where two pure-strategy equilibria can be ranked by payoff and risk dominance sequence public announcements introduces stochastic sunspot equilibria. find systematic group size effects theory fails to predict. When payoff-dominant strategy is risk...

In the present paper, the issue of the existence of optimal barter steady states is addressed in a stationary overlapping generations model with many commodities and many different long-lived consumers. A general characterization of the individual endowments leading to an optimal barter steady state is obtained. The result, which is a generalization of Benveniste and Cass (1986), is obtained as...

This paper analyzes the relationships between the values and dispersion of residential properties and the environmental-health quality of their locations. It constructs residents’ health-adjusted lifetime-utility function by combining satisfaction from consumption over the lifespan with risk to life from living in an environmentally unhealthy location. It employs this utility function to analyz...

We examine the impact of retirement exibility and the constraint against borrowing from future labor income on optimal consumption, optimal investment, and optimal retirement policy. We solve three alternative models almost explicitly in parametric forms (up to at most a constant) and provide veri cation theorems for the claimed solutions. In addition, we also obtain analytical comparative stat...
