Among health care systems with both public and private elements (such as in the US and Germany), an important question is whether the type of health insurance exerts an impact on workers' careers. We exploit the unique German case of a two-tier health care system to analyze whether opting out of...

This paper analyses the relationship between locus of control (LOC) and the demand for supplementary health insurance. Drawing on longitudinal data from Germany, we find robust evidence that individuals having an internal LOC are more likely to take up supplementary private health insurance...

Polish legislation names the general health insurance system as the main source of health care funding. Public health care funding in Poland is relatively small compared with other European countries, which restricts population’s access to medical services and exposes the health care system to...

We develop a new approach to quantify how patients respond to dynamic incentives in health insurance contracts with a deductible. Our approach exploits two sources of variation in a differences-in-regression-discontinuities design: deductible contracts reset at the beginning of the year, and...

Uniform health care delivered by a mainstream public insurer - such as the National Health Service (NHS), seldom satisfies heterogeneous demands for care, and some unsatisfied share of the population either use private health care, or purchase private insurance (PHI). One potential mechanism to...

Long waiting lines are a common feature and a major concern in many public health care delivery systems. The waiting lines are often characterized as inefficient, because they are a burden to patients without generating any gains for providers. There is an ongoing debate in Germany regarding the...

Consumers' health plan choices are highly persistent even though optimal plans change over time. This paper separates two sources of inertia, inattention to plan choice and switching costs. We develop a panel data model with separate attention and choice stages, linked by heterogeneity in...

Solidarität bedeutet in der GKV zweierlei - auf der einen Seite ein Risikoausgleich zwischen niedrigen und hohen Risiken, die alle entsprechend einer durchschnittlichen Schadenserwartung zu gleichen Bedingungen versichert werden; auf der anderen Seite ein sozialer Ausgleich, der durch die...

Starting from December 2012, insurers in the European Union were prohibited from charging gender-discriminatory prices. We examine the effect of this unisex mandate on risk segmentation in the German health insurance market. While gender used to be a pricing factor in Germany's private health...

This study examines the determinants of demand for private health insurance in Ireland. Survey data commissioned by the Health Insurance Authority from 2009 to 2017 are used to estimate multivariate models of health insurance demand. The results show that older and sicker individuals are more...

Using a randomized field experiment, we show that health care specialists cream-skim patients by their expected profitability. In the German two-tier system, outpatient reimbursement rates for both public and private insurance are centrally determined but are significantly higher for the...

A feature of many insurance markets is that they combine vertical differentiation (all consumers prefer high to low-coverage policies) and adverse selection (high cost customers prefer high-coverage plans). Building on Novshek and Sonnenschein (1978) and Azevedo and Gottlieb (2017), this paper...

Medicare pricing is known to indirectly influence provider prices and care provision for non-Medicare patients; however, Medicare's regulatory externalities beyond fee-setting are less well understood. We study how physicians' outpatient surgery choices for non-Medicare patients responded to...

Based on published estimates of its price elasticity of demand and of tax wedges, as well as the method of revealed preference, I estimate that the annual social value of ESI is about $1.5 trillion beyond what policyholders, their employers, and taxpayers pay for it. The private component of...

Who bears the consequences of administrative problems in healthcare? We use data on repeated interactions between a large sample of U.S. physicians and many different insurers to document the complexity of healthcare billing, and estimate its economic costs for doctors and consequences for...

We study how inertia interacts with market power and adverse selection in managed competition health insurance markets. We use consumer-level data to estimate a model of the California ACA exchange, in which four firms dominate the market and risk adjustment is in place to manage selection. We...

This paper explores whether Big Data, taking the form of extensive high dimensional records, can reduce the cost of adverse selection by private service providers in government-run capitation schemes, such as Medicare Advantage. We argue that using data to improve the ex ante precision of...

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...

State governments face the classic "make or buy" decision for the provision of Medicaid services. Over the past two decades, the majority of states have outsourced the provision of social health insurance through Medicaid Managed Care (MMC) programs. These programs have been extensively studied...

Polish legislation names the general health insurance system as the main source of health care funding. Public health care funding in Poland is relatively small compared with other European countries, which restricts population's access to medical services and exposes the health care system to...

States with Section 1332 Waivers to operate high-risk pools (HRPs) or reinsurance programs can receive federal pass through funds equal to reductions in federal expenditures generated by the Waiver. Shifting financial responsibility for high-cost individuals out of the Health Insurance Exchange...

While the Unemployment Insurance (UI) program is one of the largest safety net program in the U.S., research on its benefits is limited. This paper exploits plausibly exogenous changes in state UI laws to empirically estimate whether UI generosity mitigates any of the previously documented...
