Considerations
In using the GRDE for specific
studies or analyses, the following points should be considered: The GRDE estimation
is based on the national aggregation of the national income accounts. This is broken
down by regions using various indicators. Specifically, the major expenditure
items are estimated as follows:
- For Personal Consumption
Expenditure (PCE), the national estimate is distributed by region based on the
structure of the Family Income and Expenditure Survey (FIES). The final
expenditures of non-profit institutions serving households, which is included under
PCE, is the same as that of the household expenditure.
- For private construction at
constant price, regional distribution is based on the structure of the Building
Permits data. Private construction at current prices is estimated by inflating the
regional constant price level by the regional consumer price index (CPI). For public
construction disaggregation by region is based on the regional breakdown of the infra
program of NEDA and validated by the individual agencies' infra programs. An under
coverage ratio is applied for private construction which is assumed to be the same ratio
across regions.
- The regional distribution for
durable equipment is based on the results of the Annual Survey of Establishments (ASE) and
the Census of Establishments (CE). As such, the estimates are affected by the
limitations of these surveys.
- Estimates of the changes in stocks
for non-agricultural industries use the ASE/CE for regional distribution. Data for
stocks in agriculture and government are readily available.
- The General Government Consumption
Expenditure (GGCE) is estimated by region based on the data from the Commission on Audit
(COA).
Limitations
- The latest GRDE available is for
1996 since estimates of some of the expenditure items rely on the results of the ASE and
CE. The latest CE is 1994 while the latest ASE is 1995.
- In the absence of data on regional
trade flow, net exports is derived as a residual item. Hence, net
exports refer to the combined effect of the income flows between regions, the
commodity flows between regions and the rest of the world and statistical discrepancy.
