BEA Accounts
Three approaches to estimate GDP
1. Expenditures approach:
GDP = C + I + G + (X - M)
2. Income approach:
GDP = Compensation of employees
+ Gross operating surplus
+ Taxes on production and imports,
less subsidies
3. Production approach:
GDP = Gross output - Intermediate inputs

BEA’s Vision for Integrating the Accounts
• Long-term: Full Integration (2008-2010)
– Integration of all industry accounts and
integration of industry accounts with the
national income and product accounts (NIPAs)
– Provide a third independent measure of GDP
• Short-term: Partial Integration (2004-2007)
– Integration of the Annual I-O and GDP-byindustry accounts

Value Added Estimates Depend on Quality
of Data
I-O accounts
• Value added =
Gross output intermediate inputs
• Quality of gross
output is high, but
overall quality of
intermediate inputs
is not
GDP-by-industry accounts
• Value added =
Compensation of
employees + gross
operating surplus + taxes on
production and imports, less
subsidies
• Quality depends on source
data; gross operating
surplus is most problematic

Partial Integration: Five Steps to Integrate
Industry Accounts
• Develop consistent level of industry detail
• Develop revised 1997 benchmark I-O
table
• Develop time series of gross output and
value added by industry
• Apply I-O framework to develop time
series of annual accounts
• Develop real (inflation adjusted) measures

Step 2: Develop Revised 1997 Benchmark
I-O Table
• Incorporate results of 2003 NIPA
revisions
• Set best levels and composition of value
added for each industry
– Incorporate the best estimates from
both sets of accounts

Evaluation Criteria: (1) Benchmark I-O
Accounts
• Share of an industry’s intermediate
inputs covered by quinquennial
economic census
• Share of an industry’s total gross output
accounted for by quinquennial census
10
www.bea.gov
Evaluation Criteria: (2)
GDP-by-Industry Accounts
• Quality and size of adjustments made to
convert enterprise-based, profit-type
income to establishment basis
• Share of an industry’s value added
accounted for by proprietors’ income
11
www.bea.gov
Merging Information from Benchmark I-O &
GDP-by- Industry Accounts
• Based on our criteria:
– Identify point estimate and variance of value
added for each publication-level industry in the
benchmark I-O and GDP-by-industry accounts
– Develop probability distribution of value added for
each industry in each set of accounts
– Combine the two distributions to get the “best”
estimate of value added for each industry

Step 3: Time Series of Gross Output and
Value Added by Industry
• Set levels of industry gross output and value added
to the revised 1997 benchmark I-O table
• Extrapolate gross output by industry using annual
survey data from the Bureau of the Census
• Develop time series of value added by industry by
applying GDI extrapolators to 1997 levels
• Adjust industry estimates to take into account
statistical discrepancy and extrapolation errors
14

Step 4: Develop Time-Series of Balanced
Annual I-O Accounts
• Prepare annual I-O tables, given
estimates of gross output, value added,
and final demand
• Balance annual I-O tables to establish
internal consistency and consistency
with GDP-by-industry accounts

Step 5: Develop Real Measures
• Apply double-deflation procedure to
these measures of gross output and
intermediate inputs to develop real
measures of value added
17

Future Research
• Evaluate coverage, quality, and consistency
of source data from statistical agencies
• Develop additional procedures to incorporate
new data from 2002 Economic Census and
intermediate input data from expanded
annual surveys
• Develop new processes and procedures for
incorporating information from a productionbased approach to measuring GDP into the
NIPAs
