Abstract
In 2008 San Francisco implemented a pay-or-play employer mandate that required firms operating in the city to provide health
insurance coverage for employees or contribute to the cityfs gpublic optionh health access program, Healthy San Francisco.
Using data from our Bay Area Employer Health Benefits Survey, we found that in the first two years after implementation, more
employers offered insurance and provided employee health benefit coverage relative to employers outside San Francisco not
subject to the mandate. Sixty-seven percent reported in 2009 that they had expanded benefits since 2007. Although 22percentt
of firms responding to the survey reported contributing to Healthy San Francisco for some employees, we observed no crowd-out
of private insurance. Premium changes between 2007 and 2009 were similar in San Francisco and surrounding areas, but more
of the burden of premium contributions in San Francisco shifted from workers to employers. Overall, 64percent of firms respondingg
to the survey supported the employer mandate. San Franciscofs experience indicates that such a mandate is feasible, increases
access, and is acceptable to many employers, which bodes well for the national employer mandate that will take effect under
the Affordable Care Act in 2014.
San Francisco took the first steps toward achieving universal health care coverage in the city by implementing the Health
Care Security Ordinance in January2008. This ordinance included a pay-or-play employer health spending mandate, requiringg
all private-sector firms employing twenty or more workers to contribute a minimum amount to health benefits per worker-hour.
Employers can fulfill the requirement by providing private insurance, paying into a reimbursement account, or contributing
to Healthy San Francisco.
Healthy San Francisco is a low-cost health access plan created by the ordinance and administered by the cityfs Department
of Public Health. The plan covers primary care, specialty care, urgent and emergency care, laboratory tests, inpatient hospitalization,
radiology, and pharmaceuticals.
The plan strengthened safety-net services and provided a gpublic optionh as an alternative to private health insurance for
employers to choose to satisfy the mandate. Healthy San Francisco is not formally insurance, but it offers benefits tantamount
to a generous Medicaid policy, with the caveat that it is restricted to a limited network of providers located within San
Francisco, mainly composed of community health centers.1 The plan is not licensed as insurance and is not regulated by state insurance agencies.
Research on Healthy San Francisco has found high satisfaction rates among enrollees and providers as well as improved continuity
of care for patients. The plan has been cited as a potential model for improving health access in other localities. However, the employer mandate portion of the ordinance has been criticized by industry groups, such as the San Francisconci
Chamber of Commerce and the Golden Gate Restaurant Association.
The mandate was also challenged in an unsuccessful lawsuit that the Supreme Court declined to review. The plaintiffs claimed
that the mandate was overly burdensome, but it is unknown whether these concerns are shared broadly by the employer community.
Previous work has shown that although 76percent of employers had to make a change to health benefitseither by expandingin
eligibility or coverage to more workers or by increasing the generosity of benefitsin order to comply, there was early employere
support for the mandate while it was being phased in.5 This article extends that work to assess a broader range of employer responses two years into implementation.
The Affordable Care Act calls for an employer mandate of a similar magnitude to be implemented nationwide in 2014. During
2008 in San Francisco, the mandated contribution was $1.76 per worker-hour, or $3,632 annually, for each full-time worker
at firms with a hundred or more employees. Firms with twenty to ninety-nine employees were required to contribute at least
$1.17 per worker-hour. For-profit firms with fewer than twenty employees and nonprofit firms with fewer than fifty employees
were exempt.
These minimum contribution amounts were slightly less than the 2008 national average employer health insurance contribution
per employee, $3,983.6 The Affordable Care Act requires employers with at least fifty workers to pay a penalty of $2,000$3,000 per uncovered workere
for not providing coverage.7
There are many questions as to how an employer mandate will perform in practice, and little evidence to inform projections.
The Congressional Budget Office estimated that about one million people will lose employer-sponsored coverage under the Affordable
Care Act and will instead receive federally subsidized coverage through health insurance exchanges,8 while the Urban Institute and RAND reported that the law will have little effect on overall employer coverage.9,10 However, a report from the consulting firm McKinsey indicated that up to a third of employers would definitely or probably
drop coverage.11 The conflicting estimates reflect the fact that, much like San Franciscofs Health Care Security Ordinance, the Affordable
Care Act will change many variables in the way care is financed and delivered.
Local employer mandates are currently in effect in two states, Massachusetts and Hawaii, yet these mandates are very different
in character and magnitude from the national employer mandate. In Massachusetts the penalty for not providing coverage is
only $295 annually per worker, and the employer mandate is coupled with an individual mandate. Hawaii simply requires employers
to provide coverage. Research on reforms in both states found increases in the proportion of employers offering coverage,
and in Massachusetts there was no evidence of dropped coverage or restricted eligibility.
The San Francisco mandate has a minimum contribution more similar in magnitude to the Affordable Care Actfs requirement. Thus,
developments in San Francisco provide a unique opportunity to generate new evidence on the potential impact of the Affordable
Care Act employer mandate.
Specifically, we investigated the following questions: When given a pay-or-play choice, do employers comply with a mandate
by expanding private insurance, by offering a mini-medical plan (a limited benefit plan with a very low maximum annual payout,
often $10,000 or less), or by dropping private insurance? Do employer mandates increase the number of employees with health
benefits? How does the mandate affect employer and employee health insurance premiums? How supportive are employers of a pay-or-play
mandate?
We addressed these questions by studying trends in San Francisco two years after implementation, compared to trends among
firms in surrounding counties that were not subject to the law.
Study Data And Methods
Data
The primary data source for our analysis was the Bay Area Employer Health Benefits Survey, a telephone survey that was conducted
in 2008 and 2009 by the authors at the University of California, Berkeley. The survey was conducted by interviewing representatives
at firms who were responsible for company benefit decisions in San Francisco and surrounding counties. This article analyzes
for-profit firms with 20200 employees, which is the group we expected to be most affected by the mandate.17
In the Bay Area Employer Health Benefits Survey, we interviewed 349 and 329 San Francisco firms in 2008 and 2009, respectively.
We also interviewed 290 and 229 comparison firms in 2008 and 2009, respectively, from four surrounding counties not subject
to the mandate.
The sample frame included for-profit firms with twenty or more employees as listed in the Dun and Bradstreet Database and
provided by Survey Sampling, a private firm that provides sampling and data collection solutions for survey research. The
sample included the population of San Francisco firms and a random sample of firms drawn from surrounding counties.
The response rate for the survey was 20percent, creating the potential for nonresponse bias. However, we tested for suchh
bias using data from the City of San Francisco; the Dun and Bradstreet Database; the California HealthCare Foundationfs California
Employer Health Benefits Survey;18 and responses to a question on insurance offering asked of all firms, including survey nonresponders. We found that nonresponse
bias was minimal: The firms that responded to the 2008 Bay Area Employer Health Benefits Survey were similar in industry,
firm size, and geographic distribution to those that refused to participate.
The 2008 survey collected data on 2007 benefit offerings. The 2009 survey, conducted in late 2009, collected current benefit
information.
We chose Alameda, Contra Costa, Marin, and Santa Clara Counties for the survey because these counties are geographically adjacent
and contain metropolitan areas (Oakland and San Jose), and the firms there are similar in size, worker population, and industry
composition to those in our San Francisco sample (see Appendix1).19 The 2007 pre-mandate offer rate in San Francisco and surrounding counties was similar. According to the American Communityy
Survey,20 these counties were also similar to San Francisco in household size and median household income during 200610.0
Furthermore, an additional 639 firms in San Francisco and 371 firms in comparison counties refused to participate in the survey
but answered the following question: gDoes your firm currently offer health benefits to at least some of your employees?h
Ninety-three percent of the firms that completed the survey offered health insurance, compared to 91percent of the firmss
that refused to participate. Thus, although the low response rate was concerning, evidence suggested that systematic nonresponse
differences in health insurance offerings were small.
When we used our weighting scheme and limited the sample to firms with more than twenty employees in the Bay Area, our insurance
offer rate was consistent with the 95percent offer rate in the 2007 California Employer Health Benefits Survey,18 further corroborating the representativeness of our sample..
Finally, we compared our estimates of the percentage of firms contributing to Healthy San Francisco with administrative reports
from the City of San Francisco. In 2008, 980 employers had elected to pay into Healthy San Francisco, the public option, out
of what we estimatedbased on County Business Pattern data21to be approximately 4,500 total covered employers. This yielded administrative estimates of public option demand that equaledal
our survey-based estimate of 22percent.22
The Bay Area Employer Health Benefits Survey asked questions on insurance offering, plan types, premiums, changes to health
and other types of benefits, and demographic and socioeconomic characteristics of firm employees.5 The survey also included questions for San Francisco firms only on employer burden and support for the ordinance. For example,
it asked whether firms found the record-keeping and other administrative requirements of the health spending mandate to be
very burdensome, somewhat burdensome, not too burdensome, or not burdensome at all.
Methods
To investigate the extent to which health benefit changes were probably caused by the ordinance rather than reflecting broader
trends, we analyzed health benefit changes in San Francisco firms compared to changes in similar firms in surrounding Bay
Area counties not subject to the mandate. Our analysis began by evaluating health benefit offer patterns in San Francisco
and the comparison sample of firms in 2007 (before the ordinance was implemented) and 2009, including whether the firm offered
coverage, the proportion of employees eligible for coverage, and the proportion of employees taking up coverage among those
who were eligible.
Using this information, we calculated the mean proportion of employees who had health benefit coverage from their employer,
including Healthy San Francisco benefits.23 We regression-adjusted these figures to determine the difference in offering associated with the ordinance, controlling for
industry and firm size. We calculated changes in single coverage premiums between 2007 and 2009 using the Bay Area Employer
Health Benefits Survey as well as statewide trends from the California Employer Health Benefits Survey.18,24
We calculated changes made to health benefit packages, including types of benefits, and created summary indicators for any
expansions and contractions in coverage. For all analyses, we both tested for changes in outcomes within San Francisco and
tested whether these changes were different from corresponding changes outside San Francisco.
We further explored the extent of these changes among two subsets of firms with low pre-mandate health spending. The first
subset was what we called a high-impact group, composed of firms that had to increase health benefit spending by 50centss
or more per worker-hour on average according to 2007 spending patterns. The second subset consisted of firms that did not
offer any health benefits in 2007. For each of these groups, we created parallel comparison samples of firms outside of San
Francisco based on 2007 benefits, and again we tested for differences in pre-post trends in San Francisco versus comparison
firms from adjacent counties.
All results reported were weighted to reflect the population distribution of firm characteristics in the surveyed counties.
Appendix119 shows descriptive characteristics of each subsample used for analysis..
Study Results
Changes In Coverage Offered And Proportion Of Workers Covered
In 2007 the pre-implementation health insurance offering in firms subject to the ordinance was quite high, 93percent (Exhibit1).5 Between 2007 and 2009 the proportion of San Francisco firms in our weighted sample that offered health benefits rose to 96percent.nt.
Over the same period, the offer rate fell from 94percent to 90percent in the counties surrounding San Francisco. A regressionon
analysis adjusted for firm size and industry suggested that the ordinance was associated with a five-percentage-point increase
in the proportion of employers offering insurance.

firms were those that had to increase health benefit spending by 50cents or more per worker-hour on average, according too
2007 spending patterns. gWorkers with health benefitsh includes those with Healthy San Francisco. All statistics were weighted
to reflect the population of firms in San Francisco. In 2009, 4percent of workers in all firms were covered by Healthy Sann
Francisco; 7percent of workers in high-impact firms were; and 9percent of workers in firms not offering benefits in 200707
were.
When we focused on high-impact firms with low 2007 health spending, we saw a fifteen-percentage-point regression-adjusted
increase in San Francisco, while coverage outside the city remained constant. Looking at the 7percent of San Francisco firms thatt
did not offer any benefits in 2007, we saw that 60percent of those firms had begun to offer benefits by 2009. After adjustmentt
for firm size and industry, this change represented a fifty-two-percentage-point increase in offering associated with the
ordinance.
The ordinance was also associated with significant increases in the percentage of employees with health benefits from the
interviewed employer, with a five-percentage-point increase in the proportion of workers covered by employer-sponsored health
benefits or Healthy San Francisco. In contrast, the proportion of workers covered by the interviewed employer in firms outside
San Francisco dropped by five percentage points.
After adjustment for firm size and industry, the ordinance was associated with a ten-percentage-point increase in coverage
from a workerfs employer in San Francisco. These increases were mostly concentrated in the group of firms that either did not offer or had few health benefits in
2007. Coverage increased fifteen percentage points in high-impact firms and thirty-nine percentage points in firms that did not offer health benefits in 2007.
There were no significant changes in employee eligibility or take-up in firms that offered insurance during this period. This
fact indicates that increases in coverage were driven by firms newly offering coverage.
In 2009, 72percent of workers at for-profit San Francisco firms with 20200 employees were covered by insurance offered by b
the employer, and 4percent of workers were covered by Healthy San Francisco (Exhibit1). An additional 8percent of workers signed waivers indicating that they already held qualifying insurance benefits, andand
11percent were considered exempt from the mandate.25 Only 5percent of workers apparently had no health benefits.s.
Fifty-three percent of workers in high-impact firms had coverage from the employer, including 7percent in Healthy San Francisco..
In firms with no health benefits in 2007, 35percent of workers had health benefits from the interviewed employer by 2009,,
including 9percent of workers in Healthy San Francisco..
Changes In Premium Contributions
Premiums in our San Francisco sample increased 16percent between 2007 and 2009, only slightly more than in counties surroundingg
San Francisco and California generally (Exhibit2). However, the employer contribution to the premium increased 17percent in San Francisco (from $321 to $375), substantiallyly
more than in the two comparison groups. At the same time, the employee contribution increased only 9percent in San Franciscoo
(from $56 to $61), while increasing much more in surrounding counties (from $52 to $78) and California as a whole (from $50
to $67).

SOURCES Authorsf Bay Area Employer Health Benefits Survey, California Employer Health Benefits Survey (Notes18 and 24 in text). NOTES The sample was for-profit firms with 20200 employees. Firms in comparison counties were drawn from the foure f
surrounding counties of Alameda, Contra Costa, Marin, and Santa Clara. All statistics were weighted to reflect the population
of firms in these counties. The differential growth in premiums from 2007 to 2009 in San Francisco firms compared to comparison
firms from surrounding counties was significant for employee premium changes, but not for total or employer premium changes.
Absent wage reductions, these differences indicate that an outcome of the employer mandate was to shift the health coverage
costs burden toward the employer. Economic theory and some evidence suggests that workers will ultimately bear that burden
through smaller wage increases, although preliminary findings from San Francisco do not show such changes.26
Changes In Health Benefit Types
Sampled firms in San Francisco expanded health benefits along a number of dimensions after 2007 (Exhibit3). In 2009, 22percent of the firms said that they contributed to Healthy San Francisco for some workers. Sixty-seven percentnt
reported that they had expanded benefits since 2007. With the exception of adding a new high-deductible plan, the proportion
of firms reporting expansions in benefits was higher in San Francisco than in surrounding counties. Patterns were generally
analogous in the high-impact group, although a larger proportion of such firms in San Francisco offered mini-medical plans,
compared to all San Francisco firms.

in comparison counties were drawn from the four surrounding counties of Alameda, Contra Costa, Marin, and Santa Clara. All
statistics were weighted to reflect the population of firms in these counties. High-impact firms were those that had to increase
health benefit spending by 50cents or more per worker-hour on average, according to 2007 spending patterns. gExpanded coveragehâ
includes the three specific actions presented, along with increasing the employer contribution to the premium by at least
25percent, decreasing the employee contribution to the premium by at least 25percent, making an existing health plan morere
generous, adding a new insurance benefit offering, or expanding eligibility. gContracted coverageh includes the four specific
actions presented, along with increasing the employee contribution to the premium by at least 25percent or decreasing thee
employer contribution to the premium by at least 25percent. The differential change in benefits from 2007 to 2009 in Sann
Francisco firms compared to comparison-county firms was significant for expanded coverage and for health reimbursement arrangement (HRA), in both cases for all firms and for high-impact firms.
We found no evidence of crowd-out of private health plans by Healthy San Francisco. In both San Francisco and surrounding
counties, less than 1percent of firms in the 2009 survey indicated that they had stopped offering health insurance sincee
2007. In the high-impact group, 1.4percent of San Francisco firms stopped offering coverage to their workers, a figure nott
statistically different from zero; the 95percent confidence interval rules out values larger than 4percent.t.
Consistent with the changes in health benefits observed in Exhibit3, 33percent of San Francisco firms and 55percent of high-impact San Francisco firms responded that they had to increasease
spending in response to the Health Care Security Ordinance (Exhibit4). Firms in the high-impact group were significantly more likely to find it difficult to comply with the ordinance and too
find the law burdensome, compared to firms overall.

San Francisco employers were well informed about the ordinance, and support for it was strong overall.27 Although still substantial, support was significantly lower among the high-impact firms.
Discussion
In the two years following the implementation of a pay-or-play mandate in San Francisco, we found that the mandate was associated
with increases in the proportion of firms offering coverage and the proportion of workers with health benefits. We also found
no evidence of crowd-out of private employer-sponsored insurance by Healthy San Francisco, which met high demand. And we found
that coverage increases were concentrated in firms that had offered few or no health benefits prior to the mandate.
Although premium changes between 2007 and 2009 were similar in San Francisco and surrounding areas, the composition of the
premium contributions in San Francisco shifted from workers to employers. Despite being burdened with compliance, a majority
of San Francisco employers were supportive of the policy.28
There have been concerns of excess cost growth in Massachusetts under health reform.29 Similarly, an expansion in the generosity of health benefits in San Francisco could have led to an increase in total premiums,
but we found no evidence of this effect. Instead, employers appear to have responded by taking on a greater share of the premium
increases, thus slowing growth in employee contributions.
As noted above, it is important to understand that higher employer contributions to health benefits may often be funded out
of lower wage growth in the long run. Although the evidence from the San Francisco mandate in the first two years after the
ordinancefs implementation does not indicate job loss or reduction in wage growth,26 this phenomenon has been found in other settings.30,31 Furthermore, research on the San Francisco mandate has found that in restaurants, an industry greatly affected by the mandate,
firms have raised prices to consumers.26
San Francisco has achieved high levels of employer health benefit coverage, indicating that the city has met one of the overarching
goals of the ordinance. We found that compliance was high, and we estimated that only 5percent of workers were still withoutt
coverage.
Our estimates suggest that absent the ordinance, another 10percent of workers would be without employer-paid health benefits..
The high compliance rate and successful expansion of coverage has positive implications for the implementation of the national
employer mandate that will take effect under the Affordable Care Act in 2014.
Some observers have expressed concerns that employers will drop private insurance in response to pay-or-play mandates.11 We found no evidence of private insurance crowd-out in San Francisco associated with the ordinance, although we might expect
less crowd-out in this setting because Healthy San Francisco is not formal insurance. Healthy San Francisco and private health
insurance are not likely to be perceived as substitutes because of the limited provider network, the stigma associated with
public programs, and the requirement that enrollees must be uninsured for ninety days to be eligible.
More surprising is the fact that we found employers initiating insurance offerings after the mandate. Models simulating the
likely impact of the Affordable Care Act on health benefit coverage have indicated little or negative changes in employer
offering of coverage. Perhaps these models should be revisited in light of increases in the number of employers offering coverage in San Franciscois
and Massachusetts.33
These results provide evidence that an employer pay-or-play mandate can increase health benefit coverage for workers in for-profit
firms. However, San Franciscofs mandate was not designed to improve coverage levels for small business employees, dependents,
and others out of the labor force. There were also many exclusions to the employer coverage mandate: Based on our calculations
from the Dun and Bradstreet Database, about 25percent of all San Francisco workers at for-profit firms were employed at firmss
that were exempt because of size.
San Francisco has attempted to address these groups through the creation of Healthy San Francisco. Future research will be
needed to assess the impact of the ordinance on health benefit coverage and access in the overall population.
Although San Francisco has many unique characteristics that make conclusions difficult to generalize, such as high initial
rates of coverage and high levels of income, it is the closest evidence we have to an employer mandate similar in magnitude
to that in the Affordable Care Act. In addition, our conclusions have the usual limitations of self-reported survey data and
are not able to fully reflect differences in employee characteristics or richness of benefit packages.
San Franciscofs Health Care Security Ordinance has made strides toward its goal of increasing coverage for and access to health
care, partially funded with expanded financing contributions by employers. Although most firms found the ordinance administratively
burdensome, and a substantial subset of them found it difficult to comply with, it has achieved support from the majority
of San Francisco businesses. This finding of broad support is perhaps surprising, given the vocal opposition by employer groups
such as the Golden Gate Restaurant Association, which sued to block implementation of the policy.
It will be important to monitor closely the implementation of the federal employer mandate to assess how the Affordable Care
Act is received, not only by industry lobby groups but by the broader national business community. Overall, San Franciscofs
experience indicates that a strong pay-or-play mandate can be effective, feasible, and acceptable to employers.
