Reducing Administrative Barriers Increases Take-Up of Subsidized Health Insurance Coverage
Administrative barriers to social insurance program take-up are pervasive, including in subsidized health insurance. We conducted a randomized controlled trial with Massachusetts' Affordable Care Act marketplace to reduce these barriers and other behavioral frictions. We find that a “check the box” streamlined enrollment intervention raises enrollment by 10.5%, more than personalized reminder letters (7.6% increase) or generic reminder letters (4…
First Case of 2019 Novel Coronavirus in the United States
An outbreak of novel coronavirus (2019-nCoV) that began in Wuhan, China, has spread rapidly, with cases now confirmed in multiple countries. We report the first case of 2019-nCoV infection confirmed in the United States and describe the identification, diagnosis, clinical course, and management of the case, including the patient's initial mild symptoms at presentation with progression to pneumonia on day 9 of illness. This case highlights the imp…
Inferring Risk Perceptions and Preferences Using Choice from Insurance Menus
Demand for insurance can be driven by high risk aversion or high-risk. We show how to separately identify risk preferences and risk types using only choices from menus of insurance plans. Our revealed preference approach does not rely on rational expectations, nor does it require access to claims data. We show what can be learned non-parametrically about the type distributions from variation in insurance plans, offered separately to random cross-…
The Questionable Value of Having a Choice of Levels of Health Insurance Coverage
In most health insurance markets in the United States, consumers have substantial choice about their health insurance plan. However additional choice is not an unmixed blessing as it creates challenges related to both consumer confusion and adverse selection. There is mounting evidence that many people have difficulty understanding the value of insurance coverage, like evaluating the relative benefits of lower premiums versus lower deductibles. A…
Access is Not Enough
BACKGROUND: Access to physicians is a major concern for Medicaid programs. However, little is known about relationships between physician participation in Medicaid and the individual-level and practice-level characteristics of physicians. METHODS: We used the 2011 Massachusetts All Payer Claims Database, containing all commercial and Medicaid claims; we linked with data on physician characteristics. We measured Medicaid participation intensity (f…
Pricing Regulation and Imperfect Competition on the Massachusetts Health Insurance Exchange
We analyze insurance-pricing regulation under imperfect competition on the Massachusetts health insurance exchange. Differential markups lead to price variation apart from cost variation. Coarse insurer pricing strategies identify consumer demand. Younger consumers are twice as price sensitive as older consumers. Older consumers thus face higher markups over costs. Modified community rating links prices for consumers differing in both costs and p…
Designing and Regulating Health Insurance Exchanges
The Massachusetts health care reform provides preliminary evidence on the function of health insurance exchanges and individual insurance markets. This paper describes the type of products consumers choose and the dynamics of consumer choice. Evidence shows that choice architecture, including product standardization and the use of heuristics (rules of thumb), affects choice. In addition, while consumers often choose less generous plans in the exc…
