5Issues
- Health care reform debate is confusing.
- Everyone wants to know Whats in for me?
- Understanding potential spillovers of insurance/
uninsurance on local health care markets is key. - Empirical analyses based on data from the
Community Tracking Study ? Potential/realized
access and assessment of health care providers. - Policy modeling and implications.
6The uninsured population
- 45 million nonelderly uninsured in 2009.
- 54 million nonelderly uninsured by 2019.
- 65 are from low-income families (lt200 FPL).
- 35 of Latinos, 29 of Native Americans and 20
of African Americans are uninsured compared to
12 of whites. - Sources Congressional Budget Office, 2009
Kaiser Family Foundation (2006) The Uninsured, A
Primer.
7Rationale for providing access
- Good but not fully convincing argument
- It is the right thing to do
-
- Enlightened self-interest argument
- It makes you and me better off

9Local communities and uninsurance
Increased public/ Private spending
Public health services
Lower revenue for healthcare providers
Economic effects
Population health
Financial instability of Providers/institutions
Reduce charity/ uncompensated care
Access to care
10Unmet medical needs by community ranking and
insurance status
Pagán JA, Pauly MV. (2006). Community-level
uninsurance and the unmet medical needs of
insured and uninsured adults, Health Services
Research, 41(3) 788-803.
11Spillovers and vulnerability the case of
community uninsurance (Pauly and Pagán, Health
Affairs 2007)
- IOM framework High uninsurance results in higher
uncompensated care (bad debt and charity care). - End result Insured people pay for this (10
higher premiums higher prices cost-shifting). - This is a pecuniary community spillover (that is,
a financial spillover that works its way through
prices). - Local pecuniary spillovers on the insured are
likely to be small when money flows from the
outside (e.g., Medicare DSP, state funds).
12Non-pecuniary or real spillovers
- Occur when the uninsured demand a lower quality
and quantity of health care than the insured. -
- Preference externalities distinct groups of
consumers who have substantially different
preferences from others bring forth products
with more appeal to themselves but less appeal to
others (Waldfogel, 2003). - Caveat Local health care markets must not be
perfectly segmented.
13Non-pecuniary, real spillovers in partially
insured markets
- Uninsured demand lower quality care.
- Even if the insured have differential access to
health care (e.g., better facilities to go to),
there are high fixed costs for quality
differentiation.
14Example Two communities of same size and number
of uninsured
- Community 1 Uninsured never use charity care and
can only pay for low quality care. - ? Only quality spillover.
- Community 2 Uninsured get charity care and do
not skimp on quality. - ? Only pecuniary spillover.
15How can the insured reduce these negative
effects?
- By patronizing health care suppliers that do not
provide care to the uninsured or who do not
engage in cost shifting. - This can only happen in large enough markets that
can be segmented (e.g., in certain regions and
for low-fixed-cost services). - Quality spillovers are more likely in specialty
care, care requiring expensive equipment (e.g.,
scanning), etc.

17Community uninsurance and mammography (J of
Clinical Oncology April 2008)
- Women ages 40-69 from 2000-2001 CTS HS
(n12,595). - Prob of mammography screening falls by 1.3 for
every 10 increase in community uninsurance.
182009 IOM Report
- Report covers
- Health insurance coverage trends
- Health effects
- Community effects
19Pauly Pagán Spillovers of uninsurance in
communities
- 2003 CTS Household Survey ? Participants
clustered in 60 communities (48 large metro
areas, 3 small metro areas and 9 non-metro
areas). - Working age population (N 31,935).
- Health care measure f(Community uninsurance,
Charity care, X, C).
20Dependent variables
- Potential and realized health care access
- (1) Respondent has a place to go when sick
- (2) Visited doctor
- (3) Visited doctor for routine preventive care
- Assessment of health care providers
- (1) Satisfaction with choice of PCP
- (2) Satisfaction with health care received
- (3) Trust doctor
21Independent variables (distinguishing pecuniary
and real spillovers)
- Community uninsurance rate ? Proportion
uninsured. - Charity care ? Proportion of uninsured
respondents in a community with no cost-related
problems obtaining medical care. - Charity care proxy is correlated with different
sources of free care (hospitals, doctors and
FQCHCs Herring, 2005).

25Simulated Effects of Changes in Community
Uninsurance and Charity Care on Potential and
Realized Health Care Access
26Simulated Effects of Changes in Community
Uninsurance and Charity Care on Assessment of
Health Care System Providers
27Conclusion/caveats
- Model predictions depend on
- the degree of market segmentation,
- the amount of charity care (or below cost care),
and - the source of resources to cover the cost of
charity or below cost care. - Empirical evidence points to both real and
pecuniary spillovers. - The theory is value neutral ? Insurance-related
quality spillovers could be good or bad.
28Punchline
- Different approaches to cover the uninsured will
lead to different effects on the insured. - Ex 1 Increase support for safety net providers
that cater to the uninsured (e.g., community
health centers) ? little positive real spillover
on the insured. - Ex 2 Tax credits for health insurance would have
a positive real spillover on the insured.
29Agent-based model (D Damianov, JA Pagán)
- Objective Understand consequences of various
health care reform proposals. - Approach Modeling incentives to purchase
insurance and use services based on the quality
of the service provided, price, and
risk/preferences. - Model useful to understand complex social
dynamics and learning between micro/macro-level
processes. - Agents respond to their social context,
especially to the actions of other members in
their community (local health care market).
30Future
- Health care reform plans are constantly changing
How do we muddle through and get our message
across? - In making the individual, business or social case
for reform, the answer to the Whats in for me?
question should always consider the broader
community/market effects.
