We examine the effects of patient cost-sharing on adolescents' healthcare utilization and out-of-pocket medical expenditures by exploiting the healthcare reform in South Korea that lowered the coinsurance rate for inpatient care from 20% to 5% for children under 16. We apply a...

Health care markets often lack a market force because the presence of health insurance undermines price signals. Patients have little incentive to shop for low-priced alternatives because they do not bear the full cost of their health care consumption. In turn, producers lack incentives to...

Health insurance premiums often do not reflect individual health risks, implying redistribution from individuals with low health risks to individuals with high health risks. This paper studies whether more cost-sharing leads to less redistribution and to lower welfare of high-risk individuals....

The Affordable Care Act requires insurers to offer cost sharing reductions (CSRs) to low-income consumers on the Marketplaces. We link 2013-2015 All-Payer Claims Data to 2004-2013 administrative hospital discharge data from Utah and exploit policy-driven differences in the actuarial value of CSR...

Insurance for prescription drugs is characterized by two types of cost-sharing: flat copayments and variable coinsurance. We develop a theoretical model to show that refill purchases of preventive drugs (compliance) are lower under coinsurance due to the consumer's exposure to variation in drug...

Ukraine's fight for its values and its future has become an inspiration to the democratic world. That fight comes at an unthinkable human cost, and it will likely only sharpen the expectations of a strong state capable of effectively serving its citizens, who are also taxpayers. A pressing...

Two in five Americans have medical debt, nearly half of whom owe at least $2,500. Concerned by this burden, governments and private donors have undertaken large, high-profile efforts to relieve medical debt. We partnered with RIP Medical Debt to conduct two randomized experiments that relieved...

Unavailable or expensive health insurance may hinder the transition of individuals from paid employment to entrepreneurship. The literature argues that the guaranteed availability of health insurance introduced by the Affordable Care Act (ACA) of 2010 could reduce this barrier to...

Many studies have attempted to investigate the drivers of preventive behaviour. This study contributes to this strand of literature by examining the association between higher insurance deductibles in the Swiss health system and preventive behaviour that allows for maintaining a good diet,...

Objective: The ratio of controller to reliever medication use has been proposed as a measure of treatment quality for asthma patients. In this study we examine the effects of plan level mean out-of-pocket asthma medication patient copayments and other features of benefit plan design on the use...

In this paper, we use individual level data on purchases of one of the most prescribed categories of drugs (cholesterol-lowering statins) to study the responses of physicians and patients to variation in the cost of drugs. In a sample of first-time statin prescriptions to employees from a group...

We use a large data set of deductible choices in auto insurance contracts to estimate the distribution of risk preferences in our sample. To do so, we develop a structural econometric model, which accounts for adverse selection by allowing for unobserved heterogeneity in both risk (probability...

We use the design of Medicare’s prescription drug benefit program to demonstrate three facts about the health consequences of cost-sharing. First, we show that an as-if-random increase of 33.6% in out-of-pocket price (11.0 percentage points (p.p.) change in coinsurance, or $10.40 per drug)...

We use data on insurance deductible choices to estimate a structural model of risky choice that incorporates 'standard' risk aversion (diminishing marginal utility for wealth) and probability distortions. We find that probability distortions - characterized by substantial overweighting of small...

Health insurance plans increasingly pay for expenses only beyond a large annual deductible. This paper explores the implications of deductibles that reset over shorter timespans. We develop a model of insurance demand between two actuarially equivalent deductible policies, in which one...

Objective: To study how changes in insurance benefit design affect medication use of older adults with mental disorders.Data sources: US Medicare claims data from 2007 to 2018.Study Design: We focus on the gradual elimination of the Medicare prescription drug coverage gap beginning in 2011, and...

Self-quarantining expenses are probably not a deductible medical expense, under current law. I propose a statutory amendment to make them deductible under IRC section 213, provided:1) they are required by the CDC or a comparable governmental authority;2) they are limited to $200 per day for 14...

The growth of health care spending has been a longstanding policy concern. Over the years, several innovations have been proposed to lower levels of health care spending; however, their impact has been limited and not sustained over time. Costly new technology, while often an improvement to...
