Last week, the National Statistical Coordination Board
came out with the analysis report, "GDP, GDP, GDP: Who’s the FAREst ofthem all?" The article compares the economic performance of the five
presidents of the country's Fifth Republic.
NSCB, my current employer, said that among the
post-martial law presidents, President Benigno Aquino III (N. Aquino) got the
highest GDP growth rate in his first year in office with 5.4% while
former President Estrada got the lowest with 0.1%. Aquino also got the
highest GDP growth rate in his second year of service with 4.9%, while
Ramos got the lowest with 3.4%.
The article used the average annualized growth rate, a
measure of central tendency, to compare the economic performance of each
administration. While it is enlightening to parallel the average growth rates of each regime, I believe that it is equally important to consider another barometer of performance,
which is stability.
How can we measure stability and why is this
important? Businesses, and ordinary people for that matter, would want to be
situated in a stable environment. Having a turbulent economy makes it
impossible to look forward and forecast. How could a retailer project revenues if
the economy keeps on swinging from a 10% surge one quarter to a 2% slowdown the
next, to a 4% rebound the quarter after that. It would make forecasting a pain.
If a company cannot forecast its sales, it cannot forecast its profits, and if
it cannot project its profits, it would have a difficulty time deciding how much
capital to invest.
The lack of stability creates a risky environment for
businesses and investors, and we were taught in Economics 101 that we need
investments to create jobs and raise the income of the average citizen.
Economists often use the measures of dispersion, the
standard deviation and the variance are two of the most popular ones, to
estimate risk and ultimately evaluate stability.
If you have a strong foundation in mathematics,
statistics or economics, you may skip this part and move on to the next
paragraph, but for those of you who don't, carry on. The measures of dispersion
would give us a summary on spread of the data in a given set. It gives us a
sense on how distant the observations are from one other. When the value of
the measures of dispersion is high, then it is likely that observations in your
data set are really distant from each other. For example, data set A (8,
56, 16, 6, 105, 2) would have a standard deviation* of 43, compare it to the
data set B (1, 2, 2, 1, 5), which would have a standard deviation of 2. Notice
how far way the values of each observations in set A are and how that resulted
into set A having a significantly higher standard deviation compared to set B.
I've taken the liberty of computing for the standard
deviation of annual GDP growth rates of the Corry Aquino (C. Aquino), Ramos, Estrada, and
Arryo administrations. I felt that it was unfair to include the performance of
the N. Aquino administration in the analysis since his term is still on-going.
One may argue that the same consideration must be given with Estrada's, since
his time in office was cut short by the revolt which launched Arroyo into
power,. However, I believe that there is credit in including Estrada's administration in
the analysis since his term has ended and the data needed to evaluate the
overall stability of his entire regime is already complete.

Based on the estimates, it is during the regime of
former President Arroyo when the country experienced the least variability in
terms of GDP fluctuation. The standard deviation of the GDP growth rates of the
president, who is now facing criminal charges for corruption, was at 1.9,
substantially lower compared to the standard deviation of the growth rates
during the time of Estrada (2.13), Ramos (2.5), and C. Aquino (2.77). This
means that despite the roller coaster boom and bust the country experienced
during Arroyo's regime (GDP growth peaked growing at 6.6% in 2004, then it
suddenly dropped to 1.1% two years later due to the Wallstreet Meltdown), the
economy was still at its most stable.
I also thought that it would be interesting to find
out which administration was most stable in the first 10 quarters of their terms. This is the
most objective way, I believe, we can compare the stability of the N. Aquino
administration with the administration of his predecessors. I computed for the standard deviation the growth rates of all five
presidents in the first 10 quarter of their terms.
According to the estimates, the Arroyo regime still
has the smallest standard deviation, at 0.99, suggesting that the economy during her first two years in office was still the most stable. The standard deviation for N. Aquino's
regime only came in second, at 1.5. The standard deviation for C. Aquino,
Ramos, and Estrada were estimated at 2.28, 1.9, and 2.6, respectively.
After giving it a lot of thought, I'm inclined to
believe that the level of standard deviation in the first 10 quarters of the
Arroyo rule may not necessarily be the result of her administration's policies. Normally, the first few quarters
of a government regime would start from a high base because the previous year
would be an election year. Election spending often fuels the economy. A slowdown usually follows an election year
since the political spending would come to a stop by then. This is called the high-base
effect. The sharp slowdown would reasonably result to a high discrepancy
between the GDP growth of the first and second year in office, ultimately
causing the standard deviation to be higher.
In Arroyo's case, there was no election prior to the
start of her term. She was put to office by a popular revolt. There would be no
base-effect to cause a discrepancy in the growth rates in the first two years
of her term. Standard deviation would be moderate.

My goal in writing this blog entry is to provide
addition insight and supplement the information provided by NSCB. I admit that
there are weaknesses the methodology used.
As the NSCB article said, "some analysts suggest that the changes
in GDP mirror how Philippine presidents and their economic managers manage our
economy. Of course, other analysts would think that this may be far too
simplistic given that the starting conditions and other factors, including the
external environment, were not the same across the periods of these
Presidents." However, I believe that my analysis would somehow contribute
to the on-going discourse on public policy and macroeconomic trends.
*the formula for the standard deviation is as follows:
