This paper analyzes optimal and equilibrium insurance contracts under adverse selection and moral hazard, comparing them with those under a single informational asymmetry. The complex interactions of self-selection and moral hazard constraints have important consequences. We develop an analytic...

We study the Rothschild-Stiglitz model of competitive insurance markets with endogenous information disclosure by both firms and consumers. We show that an equilibrium always exists, (even without the single crossing property), and characterize the unique equilibrium allocation. With two types...

In theory, guaranteed renewable (GR) insurance contracts can efficiently insure against reclassification risk without causing adverse selection on pre-existing conditions. In practice, however, adverse selection can still arise on other dimensions. In 2020, in response to protests demanding...

This article reverses the standard conclusion that asymmetric information plus competition results in insufficient insurance provision. Risk-tolerant individuals take few precautions and are disinclined to insure, but they are drawn into a pooling equilibrium by the low premiums created by the...

Should choice be offered in social insurance programs? The paper presents a conceptual framework that identifies the key forces determining the value of offering choice, reviews some existing evidence on these forces, and aims to guide further empirical research in different in- surance domains....
