Background: Dispelling misinformation during crises is of critical importance. But information can also induce distress, which can lead to poor decision-making. We ask whether delivering correct information hurts or improves mental health during the Covid-19 pandemic. Methods: We randomly assigned a sample of low-income migrant workers to receive Covid-19-related information through text messages, a pre-recorded audio message, or (live) phone calls. Results: Misinformation was rampant at baseline. Phone calls led to the greatest increase in Covid-19-related knowledge, particularly among those without smartphones. They also reduced depression and anxiety substantially. The amount of information delivered explains gains in knowledge, but not improvements in mental health. Conclusions: These results suggest that governments reconsider the dependence on text messages and pre-recorded audio given the mental health improvements created by live phone calls. Trial Registration: The trial was pre-registered with the American Economic Association's Trial Registry (doi: 10.1257/rct.5947). Funding: Good Business Lab funded the data collection and interventions. Declaration of Interests: Adhvaryu and Nyshadham disclose that they are members of the Board of Directors and serve as Chief Development Officer and Chief Strategy Officer, respectively, at Good Business Lab. None of the authors has any financial interest in GBL. Ethics Approval Statement: This study was approved by Good Business Lab's Ethics Committee in India (Identifier: GBL0520) and University of Michigan Human Subjects Research Committee in the United States (Office of Human Research Protections Registration Number: IRB00000246). We obtained informed consent from all study participants.

We study the role of household enterprise as a coping mechanism after health shocks. Using variation in the cost of traveling to formal sector health facilities to predict recovery from acute illness in Tanzania, we show that individuals with prolonged illness switch from farm labor to enterprise activity. This response occurs along both the extensive (entry) and intensive (capital stock and labor supply) margins. Family members who are not ill exhibit exactly the same pattern of responses. Deriving a simple extension to the canonical agricultural household model, we show that our results suggest complementarities in household labor.
