We present robust evidence on the presence of adverse selection in hospitalization insurance for low-income households. A large randomized control trial from Pakistan allows us to separate adverse selection from moral hazard, to estimate how selection changes at different points of the demand...

I evaluate the accuracy of people's subjective probability expectations for using various health services. Subjective expectations closely reflect patterns of observed utilization, are predicted by the same covariates as observed utilization, and correlate with objective measures of risk. At the...

Despite widespread exposure to substantial medical expenditure risk in low-income populations, health insurance enrollment is typically low. This is puzzling from the perspective of expected utility theory. To help explain it, this paper introduces a decomposition of the stated willingness to...

We examine economic vulnerability to illness when, as for informal sector workers in Thailand, there is universal coverage for health care but earnings losses are uninsured. Even with comprehensive health care entitlement, severe illness that strikes an initially healthy worker is found to raise...

Child labor is a common consequence of economic shocks in developing countries. We show how reducing vulnerability can affect child labor and schooling. We exploit the extension of a health and accident insurance scheme by a Pakistani microfinance institution (MFI) that was set up as a...

This paper analyzes whether Mexico's de-facto non-contributory health insurance program Seguro Popular had an effect on the risk of miscarriage during pregnancy. Using data on pregnancies over the 2004-08 period from the 2009 round of the National Survey on Demographic Dynamics (ENADID), and...

Using the expansion of a large-scale health insurance program in Mexico and variation in local rainfall levels, I estimate whether the program-induced increase in healthcare coverage protected the educational attainment of primary school children in the event of adverse climatic shocks. Results...

We analyze short-term effects of free hospitalization insurance for the poorest quintile of the population in the province of Khyber Pakhtunkhwa, Pakistan. First, we exploit that eligibility is based on an exogenous poverty score threshold and apply a regression discontinuity design. Second, we...

In many markets insurers are barred from price discrimination based on con- sumer characteristics like age, gender, and medical history. In this paper, I build on a recent literature to show why such policies are inefficient if consumers differ in their willingness-to-pay for insurance...

We study the consequences of imposing a minimum coverage in an insurance market where enrollment is mandatory and agents have private information on their true risk type. If the regulation is not too stringent, the equilibrium is separating in which a single insurer monopolizes the high risks...
