Abstract
We conduct a randomized laboratory experiment examining the e ffects of stress (implemented using four methods) on temporal discounting, eff ort provision, and executive control. Our study includes 1142 subjects from the informal settlements in Nairobi, Kenya. Respondents are randomly administered either a control or a treatment (stress) protocol, for seven consecutive days. This allows us to estimate the causal impacts of stress on decision-making after one and seven days of administration.

Experimental Details
Interventions
Intervention(s)
We induce stress in four diff erent ways across subjects: the Trier Social Stress Task (TSST) which induces psychosocial stress, physical stress using the Cold Pressor Task , fi nancial stress using the Centipede Game, and using hydrocortisone administration to induce the neurobiological consequences of stress.
