Gross value added (GVA) is a measure of economic activity that represents the total value of goods and services produced in an area. It can be calculated using an output, income, or expenditure approach. While GVA indicates economic scale and growth, it does not directly measure well-being as it ignores issues like income inequality, environmental impacts, and how production is used. Gross disposable household income (GDHI) measures amounts available for households to spend or save after taxes and represents a redistributive effect across areas. The regional index of sustainable economic well-being (R-ISEW) attempts to incorporate social and environmental factors into the analysis framework alongside economic indicators.

3. Gross Valued Added (GVA):Gross Valued Added (GVA):
Total value of goods and services
produced through economic activity in any
particular period
• GVA = GDP - Taxes + Subsidies (GDP is at market
prices)
• Taxes and subsidies not part of the value added in
production
• GDP = national; GVA = regional
• GVA = Output = Income = Expenditure…

6. (2) Income approach(2) Income approach
• Income of all those involved in production process
• Includes:
– Compensation of employees (wages and salaries)
~60%
– Operating surplus (profit, interest…etc) ~30%
– Mixed incomes (sole traders and self-employed)
~10%
• Excludes:
– Transfer payments (pensions and social security);
Direct taxes; ‘Shadow Economy’
7. (3) Expenditure approach(3) Expenditure approach
The value of expenditure on goods and
services
C + G + I + X – M
C = Consumer expenditure on goods & services
G = Government expenditure
I = Investment in buildings and machinery
X-M = Exports minus imports
8. What is the GVA for Company A?What is the GVA for Company A?
Company A
Sales £100
Cost of Sales £30
Wages £40
Expenses £20 £90
Net profit £10
GVA for Company A £50
Sales - CoS - Expenses £50
Wages + net profit £50
Other calculations:
Employment based:
Net additional employment x GVA per FTE
for sector
Turnover based:
Turnover x Turnover :GVA ratio for sector

10. ProductivityProductivity
How efficiently factors of production (land,
labour and capital) are used in the
production process
• GVA per job or GVA per hour
• GVA per head as a proxy (from ONS)
–Resident vs. workplace: commuting effects
–Non-active population factor
13. • Indicator of scale and growth
• Comparisons across time & place (but time lags)
• Established methodology
• Limitations are well documented
– Does not directly measure well-being; ‘Threshold hypothesis’
– Distribution; Income inequality
– Ignores externalities e.g. environmental
– Includes ‘bads’ i.e. more expenditure on health care due to stress
– To be considered alongside other economic, environmental and
social indicators

Well-being (R-ISEW)Well-being (R-ISEW)
• Monetises social and environmental issues bringing
them into the same analytical framework as economic
indicators
• First ISEW by Cobb & Daly in 1989
• First UK ISEW by nef and Professor Tim Jackson, University of Surrey
in 1994
•First R-ISEWs for all regions supported by RDAs, calculated in 2007
23. R-ISEW = Personal consumer expenditure
- adjustment for income inequality
+ public expenditures (non-defensive)
+ value of domestic labour & volunteering
+/- economic adjustments (net international position, net
capital growth, consumer durables)
- defensive private expenditures
- costs of environmental degradation
- depreciation of natural capital

26. ConclusionsConclusions
• Must fully understand the benefits and limitations of indicators.
• GVA measures the total value of goods and services produced
through economic activity.
• ‘Circular flow’: GVA = Output = Income = Expenditure
• Productivity describes how efficiently an economy is using its
resources.
• GDHI measures how much consumers have available to spend in
the economy and reveals a ‘redistributive effect’.
• The R-ISEW attempts to bring a number of indicators into a single
framework. An effective model?
