Economic Activity Index (“GDB-EAI”)
February 2014
General Commentary – February 2014
The February 2014 EAI was 127.1, a 2.4% reduction compared to February 2013. Moreover, the FY2014 YTD (July- February) EAI showed a reduction of 3.8% with respect to the corresponding figure for FY2013.
Total non-farm payroll employment for February 2014 averaged 929,200, an annual increase of 0.1%, while FY2014 YTD total non-farm payroll employment showed a 1.9% decrease with respect to the corresponding figure for FY2013. During this month, total private employment increased by 1.5% y-o-y (10,300 jobs), while total public employment decreased by 3.7% y-o-y (9,300 jobs).
Electric power generation for February 2014 totaled 1,528.0 million kWh, an annual decrease of 2.2%. Electricity generation for FY2014 YTD was 3.6% less than during the same period of FY2013.
The preliminary number for gasoline consumption* in February 2014 was 80.5 million gallons, 6.4% below February 2013. The FY2014 YTD gasoline consumption number was 3.1% below the corresponding figure for FY2013.
Cement sales for February 2014 totaled 1.27 million bags, registering an annual reduction of 12.7%. Sales for FY2014 YTD were 15.6% below the figure for the same period of FY2013.

In February 2014, the GDB-EAI registered a 2.4% year-over-year (y-o-y) reduction (the
lowest since May 2013), after showing a 3.4% y-o-y decrease in January 2014.
* The monthly gasoline consumption is estimated by the GDB from the Treasury Department's monthly gasoline excise tax collections paid by importers
which are transferred to P.R. Highways and Transportation Authority. These collections fluctuate due to changes in inventories and purchases, which
do not necessarily reflect the actual monthly consumption reported by retailers.

• The complete series of the EAI, which starts in January 1980, shows the recessions of FY1982 and FY1983, the
mild recession of FY1991, the recession of 2001, and the sharp but temporary effects of two hurricanes. It also
shows the path of the Index since the beginning of the current recession.

Forthcoming changes
In order to further reduce the volatility of the Index, the Economic Analysis Division is
testing different seasonal adjustment procedures.
The change in the current seasonal adjustment procedure would allow more reasonable
month-over-month comparisons for the monthly observations of the index.
The selected seasonal adjustment procedure will be implemented in the April 2014
release.

Description of the
GDB-Economic Activity Index

Advantages of the GDB-EAI:
Readily available
Highly correlated to Puerto Rico’s real GNP
Reliable tool to monitor actual trend of Puerto Rico economy
The GDB-EAI is made up of 4 indicators:
Total Payroll Employment (Establishment Survey/ Thousand of employees)
Total Electric Power Generation (Millions of kWh)
Cement Sales (Millions of bags)
Gas Consumption (Millions of gallons)
GDB-EAI Highlights and Composition
GDB Economic Activity Index Highlights
10
The GDB-EAI is a coincident index for the economic activity of Puerto Rico. It is highly correlated
to Puerto Rico’s real GNP not only on the levels, but also on the annual growth rates.
This index was developed following the methodology similar to that used by The Conference Board
in their coincident index. This methodology follows a standard procedure to adjust the data for
seasonality and volatility factors.

Clarification about the interpretation of
the GDB-EAI figures
When it is annualized, the level of the EAI is highly correlated with the level of the
real GNP (with a Pearson correlation coefficient of 0.9886, for FY1981-FY2012).
The annual growth rates of both variables are also highly correlated (with a Pearson
correlation coefficient of 0.9508, for FY1982-FY2012).
Nevertheless, the annual growth rate of the EAI IS NOT the same as the annual growth
rate of the real GNP. Being highly correlated does not mean being equal.
In order to approximate real GNP growth from the EAI annual growth, we estimate a
linear regression model relating both variables.
Plugging in the EAI annual growth rates into the resulting equation we obtain estimates
for the annual growth rates of the real GNP.
This transformation generates an approximation of the actual real GNP growth figures.
12
The GDB-EAI is an indicator of the general economic activity, not a direct measurement of
the real GNP. Moreover, the GDB-EAI annual growth rates are not the same as the real GNP
growth rates, because the former are more volatile than the latter.
Clarification about the interpretation of
the GDB-EAI figures (2)
13
Here is a comparison of the annual growth rates of the GDB-EAI with the actual real GNP
figures. There are also estimates of the annual growth of the real GNP using the figures
coming from the GDB-EAI.
• Notice that the real GNP growth estimates
coming from the EAI are relatively close to the
actual real GNP growth figures.

Here is a comparison graph of the actual real GNP figures and the estimates of the annual
growth of the real GNP using the figures coming from the GDB-EAI.

The GDB-EAI and its indicators are subject to
revisions. While the information comprising the GDB EAI
has been obtained from sources GDB believes to be
reliable, GDB is not responsible for any errors or
omissions, or for the results obtained from the use of this
