Health insurance markets in the United States are characterized by imperfect information, complex products, and substantial search frictions. Insurance agents and brokers play a significant role in helping employers navigate these problems. However, little is known about the relation between the structure of the agent/broker market and access and affordability of insurance. This paper aims to fill this gap by investigating the influence of agents/brokers on health insurance decisions of small firms, which are particularly vulnerable to problems of financing health insurance. Using a unique membership database from the National Association of Health Underwriters together with a nationally representative survey of employers, we find that small firms in more competitive agent/broker markets are more likely to offer health insurance and at lower premiums. Moreover, premiums are less dispersed in more competitive agent/broker markets.

NEW EVIDENCE ON EMPLOYER PRICE-SENSITIVITY OF OFFERING HEALTH INSURANCE
January 2014
Working Paper Number:
CES-14-01
Economic incentives such as the preferential tax treatment of premiums and economies of scale encourage employers to provide health insurance through the workplace. The employer's decision to offer health insurance depends on how much workers value insurance relative to wages, and that value is likely to vary, given the composition of the establishment's workforce. Using the 2008-2010 MEPS Insurance Component augmented with information from other data sources, we generate new estimates of employers' price-sensitivity of offering insurance. Our results suggest that employers are sensitive to changes in the tax price of insurance, with very small employers exhibiting the largest price-sensitivity. Employer size, workforce composition, and local labor market conditions also influence the employer's decision to offer insurance. New evidence can inform policy discussions about the implications of broad-based reforms that change marginal tax rates as well as targeted strategies that address the tax-exempt status of premiums.

HOW WILL THE AFFORDABLE CARE ACT CHANGE EMPLOYERS' INCENTIVES TO OFFER INSURANCE?
January 2014
Working Paper Number:
CES-14-02
This study investigates how changes in the economic incentives created by the Affordable Care Act (ACA) will affect the probability that private-sector U.S. employers will offer health insurance. Using the Medical Expenditure Panel Survey Insurance Component for 2008-2010, we predict employers' responses to key ACA provisions. Our simulations predict that overall demand for insurance will rise, driven by workers' desire to avoid the individual mandate penalty and the availability of premium tax credits in exchanges. Our analyses also suggest that the average probability of an establishment offering insurance will decline from .83 to .66 with ACA implementation, although there is considerable variation by firm size, industry and union status.

Declines in Employer Sponsored Coverage Between 2000 and 2008: Offers, Take-Up, Premium Contributions, and Dependent Options
September 2010
Working Paper Number:
CES-10-23
Even before the current economic downturn, rates of employer-sponsored insurance (ESI) declined substantially, falling six percentage points between 2000 and 2008 for nonelderly Americans. During a previously documented decline in ESI, from 1987 to 1996, the fall was found to be the result of a reduction in enrollment or 'take-up' of offered coverage and not a decline in employer offer/eligibility rates. In this paper, we investigate the components of the more recent decline in ESI coverage by firm size, using data from the MEPS-IC, a large nationally representative survey of employers. We examine changes in offer rates, eligibility rates and take-up rates for coverage, and include a new dimension, the availability of and enrollment in dependent coverage. We investigate how these components changed for employers of different sizes and find that declining coverage rates for small firms were due to declines in both offer and take-up rates while declining rates for large firms were due to declining enrollment in offered coverage. We also find a decrease in the availability of dependent coverage at small employers and a shift towards single coverage across employers of all sizes. Understanding the components of the decline in coverage for small and large firms is important for establishing the baseline for observing the effects of the current economic downturn and the implementation of health insurance reform.

Manufacturing Firms' Decisions Regarding Retiree Health Insurance
June 2003
Working Paper Number:
CES-03-14
This study analyzes the firm's decision to offer and contribute to retiree health insurance. We apply a binomial probit model and an interval regression model to analyze the likelihood of offering and the proportion of costs contributed by the firm. Our findings indicate that while firm characteristics affect the probability that a firm offers retiree health insurance, financial performance and alternative insurance options significantly affect the firm's generosity towards its cost. This study expands on previous research by including potentially important policy-related measures to the more limited set of firm and workforce characteristics that have been typically employed.

Contributions to Health Insurance Premiums: When Does the Employer Pay 100 Percent?
December 2005
Working Paper Number:
CES-05-27
We identify the characteristics of establishments that paid 100 percent of health insurance premiums and the policies they offered from 1997-2001, despite increased premium costs. Analyzing data from the MEPS-IC, we see little change in the percent of establishments that paid the full cost of premiums for employees. Most of these establishments were young, small, singleunits, with a relatively high paid workforce. Plans that were fully paid generally required referrals to see specialists, did not cover pre-existing conditions or outpatient prescriptions, and had the highest out-of-pocket expense limits. These plans also were more likely than plans not fully paid by employers to have had a fee-for-service or exclusive provider arrangement, had the highest premiums, and were less likely to be self-insured.

Health-Related Research Using Confidential U.S. Census Bureau Data
August 2008
Working Paper Number:
CES-08-21
Economic studies on health-related issues have the potential to benefit all Americans. The approaches for dealing with the growth of health care costs and health insurance coverage are ever changing and information is needed on their efficacy. Research on health-related topics has been conducted for about a decade at the Census Bureau\u2019s Center for Economic Studies and the Research Data Centers. This paper begins by describing the confidential business and demographic Census Bureau data products used in this research. The discussion continues with summaries of nearly 30 papers, including how this work has benefited the Census Bureau and its research findings. Some focus on data linkages and assessing data quality, while others address important questions in the employer, public, and individual insurance markets. This research could not have been accomplished with public-use data. The newly available data from the Agency for Healthcare Research and Quality and National Center for Health Statistics, as well as additional Census Bureau data now available in the Research Data Centers are also discussed.

The Underserved Have Less Access to Employer-Sponsored Telemedicine Coverage
September 2022
Working Paper Number:
CES-22-40
Telemedicine has been proposed as one means of improving health care access for underserved communities, and information about insurance coverage for telemedicine (TMC) is important in understanding its utilization and provision. We use 2018-2019 Medical Expenditure Panel Survey-Insurance Component data on employer-sponsored coverage to examine pre-pandemic TMC relative to employer, worker, and health plan characteristics. We find that the share of employees in private sector establishments offering TMC was lower in the most rural counties, in smaller firms, in establishments without unionized employees, and in establishments where most workers were low wage, part-time and older when compared to other establishments. These findings reflect differences across establishments in insurance offers, as well as differences in TMC conditional on an insurance offer, which suggests that TMC may function as a premium plan feature with limited availability and potential support for improving healthcare access for the underserved.

Estimating the Costs of Covering Dependents through Employer-Sponsored Plans
January 2017
Working Paper Number:
CES-17-48
Several health reform microsimulation models use synthetic firms to estimate how changes in federal and state policies will affect employers' offers of health insurance, as well as the price of health insurance for workers and firms. These models typically rely on distinct measures of the average costs of single and dependent coverage, for employees and employers, which do not capture the joint distribution of these costs. Since some firms pay a large share of the premium for single polices but a lower share for dependent coverage, or the reverse, simulation models that do not account for the joint distribution of premium costs may not be sufficient to answer certain policy questions. To address this issue, we developed a method to extract estimates of the joint distribution of employer and employee costs of health insurance coverage from the Medical Expenditure Panel Survey ' Insurance Component (MEPS-IC). This paper describes how these distributions were constructed and how they were incorporated into the Urban Institute's Health Insurance Policy Simulation Model (HIPSM). The estimates presented in this paper and those available in supplementary datasets may be useful for other simulation models that need to utilize information on the joint distribution of single and dependent employee premium contributions.

Why are employer-sponsored health insurance premiums higher in the public sector than in the private sector?
February 2019
Working Paper Number:
CES-19-03
In this article, we examine the factors explaining differences in public and private sector health insurance premiums for enrollees with single coverage. We use data from the 2000 and 2014 Medical Expenditure Panel Survey-Insurance Component, along with decomposition methods, to explore the relative explanatory importance of plan features and benefit generosity, such as deductibles and other forms of cost sharing, basic employee characteristics (e.g., age, gender, and education), and unionization. While there was little difference in public and private sector premiums in 2000, by 2014, public premiums had exceeded private premiums by 14 to 19 percent. We find that differences in plan characteristics played a substantial role in explaining premium differences in 2014, but they were not the only, or even the most important, factor. Differences in worker age, gender, marital status, and educational attainment were also important factors, as was workforce unionization.

The Dynamics of Market Structure and Market Size in Two Health Services Industries
October 2007
Working Paper Number:
CES-07-26
The relationship between the size of a market and the competitiveness of the market has been of long-standing interest to IO economists. Empirical studies have used the relationship between the size of the geographic market and both the number of firms in the market and the average sales of the firms to draw inferences about the degree of competition in the market. This paper extends this framework to incorporate the analysis of entry and exit flows. A key implication of recent entry and exit models is that current market structure will likely depend upon history of past participation. The paper explores these issues empirically by examining producer dynamics for two health service industries, dentistry and chiropractic services. We find that the number of potential entrants and past number of incumbent firms are correlated with current market structure. The empirical results also show that as market size increases the number of firms rises less than proportionately, firm size increases, and average productivity increases. However, the magnitude of the correlations are sensitive to the inclusion of the market history variables.
