Efficiency of Public Spending on Health
Introduction Background:
• The 1998 Constitution established a new political formulation of the health services in the country.
The new system was grounded on three principles: Universality, Integrality and Equity.
• In addition to the those principles, others were created to organize the process. Decentralization
stands out among them.
• In 1990, Law 8.080 linked the decentralization to municipalization.
• In 2000, the Constitutional Amendment Number 29 established how much each Federative
Unit had to invest. The Federal Government is the main financial agent of the public health
network.
• The Amendment was regulated by a Complementary Law in January 2012. The Law states
what can be considered expenses on the health area and what cannot. However, it does not
bring any novelty concerning Deadlines or Sanctions.

Transfers Scheme – How is it related to efficiency?
Law 8.080/1990: The transfer of health resources to states and municipalities will be
based on:
I. Demographic profile
II. Epidemiological profile
III. Quantity and Quality of Health Services
IV. Technical, economic and financial performance in previous years
V. Health share in local budget
VI. A 5-year investment plan
VII. Reimbursements from other government levels
VIII. Half of the resources will be distributed according to the number of
inhabitants
IX. Special criteria may apply to states and municipalities with high migration flows 7
Efficiency of Public Spending on Health
Motivation
Public Spending on Health and Intergovernmental Transfers
Based on the criteria listed in the referred law, this paper examines if - and how - the
technical criteria set out in the act 35 of Law 8.080/1990 for the distribution of
resources related to the efficient management of health services in the Federal States.
Therefore, we use a measure of efficiency based on Stochastic Frontier where the
input is public spending on health, whereas health care products are
consultations, hospitalizations, tests and number of beds in the Unified Health
System (SUS) for the period 2000 to 2008.

Methodology
Battese and Coelli (1995)
Estimation of a Cost Function to evaluate the inefficiency component
The stochastic frontier for panel data is modeled as:
is governmental spending in health at time t, by unit i
is a vector of healthcare services
are variables explaining the inefficiency term
is defined by a Normal distribution truncated in
In this cost function, the Uit now defines how far the firm operates above the cost frontier.

Efficiency of Public Spending on Health
•Concerning Table 4 first part, the signs of the coefficients of the stochastic frontier
are as expected, with the exception of the negative estimate of the number of
hospitalizations and beds variables. It s possible that scale effects are causing noise in
estimating, that is, states that operate in large scale also have more hospital beds. So,
that can interfere in the results. That result is counterintuitive and will be looked into
afterwards.
•Concerning Table 4 second part - the estimated coefficients in the inefficiency
model are of particular interest to this study:
Concerning sanitation, the negative coefficient indicates that an improvement in
the variables related to sanitation such as water supply, sewers and garbage
collection are associated with a decrease in the lack of efficiency in the public
health service.

Efficiency of Public Spending on Health
Demography has a negative coefficient, showing a direct relation between an improvement
in that coefficient and health expenditure efficiency. That phenomenon may be linked to the
system s adaptation to cater for an increase in the demand for health services due to na increasing
elderly population.
Income is significant and has a positive coefficient. Notice that a higher income per capita
enables the population to make use of private hospitals, thus reducing demand in the public health
system, which does not incite an increase in efficiency as there is a reduction in the number of
consultations, examinations, hospitalizations and beds. Conversely, the growth in the low-income
population calls for more public health service demand.
Epidemiological variables were also significant and negative results which indicate that the
public system has to adapt to the increase in the demand due to epidemics, that is, an
epidemic outbreak makes the state react more efficiently in providing health services to see to the
stricken population.

Public Policies Implications
•Concerning the estimated elasticities, the results show that the increase in the number of
consultations and clinical examinations leads to an augmentation in health expenditure. Furthermore,
we can see that the increase in the health service efficiency is associated with sanitation,
demographic characteristics of the population, level of income and epidemics.
•According to the criteria stablished by Law number 8.080 of 1990 act 35, the increase in the
health service demand makes the state react more efficiently in relation to those target
populations.
•However, the state s reaction does not necessarily entail providing high standards of public
health service. There is the need for research to investigate this topic carefully, using different
methodological approaches.
