Summary of the impact
This impact case study is based on research concerning the estimation of
regional economic impacts through input-output models and spatial
econometrics. The research resulted in the distribution of a free
modelling software package to decision-makers throughout the South West
region and has had policy impacts in terms of the influence of advice,
data, and reports provided to a range of organisations including the South
West Regional Development Agency, Plymouth City Council, and several other
local councils and private sector decision-makers.
Underpinning research
The underpinning research has been primarily undertaken by Paul Bishop
(currently Professor of Economics, Plymouth University and located at
Plymouth for the entire case study period). The genesis of the research
was a Ph.D. undertaken by Dr Steven Brand at the University of Plymouth
(awarded 1998) Dr Brand is now Associate Professor of Economics, Plymouth
University, located in Plymouth for the entire case study period apart
from 1996-1998 when at University of Cardiff. The Ph.D. was supervised by
Professor Bishop and entitled A Reassessment of the Hybrid Approach to
the Construction of Regional Input-Output Tables. Theoretical
innovations related to this research were associated with novel methods of
estimating regional trade [1], the use of locations quotients in IO models
[2] and the reappraisal of the use of such models for local impact
analysis [3]. Much of the research took place within CEMLEF by the
Economics Research Group in co-operation with Professor Peter Gripaios
(currently emeritus Professor of Economics, formerly Professor of
Economics - located at Plymouth during entire case study period - retired
2009).
Our expertise in regional modelling was recognised by the award of
substantial funding (totaling £437,000) in the form of research grants
from the South West Regional Development Agency (SWRDA), primarily for the
construction of regional accounts, the building of input-output models and
further theoretical research on IO models and spatial linkages. The
Regional Accounts brought together the best sources of published and
unpublished economic data in a structured way. This lowered the costs of
regional economic analysis whilst maximising the usefulness of otherwise
disparate resources (e.g. facilitating productivity analysis or economic
impact analysis). The Accounts quickly became an integral part of economic
intelligence and analytical capacity within the region. Software based on
the model has been made available as a public good throughout the region
since the mid-2000s and has been used by SWRDA, local authorities and
other private and public organizations. Insights from the research were
utilised and further developed in the construction of Welsh Input-Output
tables (in collaboration with University of Cardiff) and for evaluating
the impact of foreign manufacturing. The adaptable nature of the modelling
techniques can be demonstrated by reports produced for a range of clients
during the 2000s including economic assessment of the move of the Met.
Office to Exeter, the sinking of HMS SCYLLA as a diving attraction, a
proposed Marine Science Park and the case for a New Devon Airport. The
development of the IO model was the centre of a wider research program
developed within the unit. As a consequence of expertise in regional data,
members were the first to publish analyses of new data available from the
Government Experimental Accounts, which facilitated a detailed examination
of the spatial impact of the public sector, producing new insights into
the nature of spatial inequalities [4]. IO also facilitates a detailed
examination of industrial structure and inter-industry linkages. This led
to an on-going research program examining the impact of industrial
structure and the diversity of that structure on sub-regional GDP through
the application of spatial econometric models. Members of the group have
pioneered the use of spatial econometrics in some regional applications
demonstrating that empirical conclusions can be altered by inclusion of
spatial effects through spatial lag and error models. The results were
amongst the first to highlight the employment dynamics and spillover
effects characterising different types of industries and employ spatial
autocorrelation modelling to produce better specified models. [5, 6]

Details of the impact
The major elements of research that underpin its wider impact include new
techniques for the development of IO models, the construction of Regional
Accounts and the widespread application of these and associated modelling
techniques. The suite of techniques is now referred to as the AMORE
solution (Advanced Modelling of Regional Economies). A central principle
of the IO project was that the modelling resource was a public good. The
resource was therefore used by SWRDA, Local Authorities, consultants and
academic researchers. SWRDA's use has included informing the Agency's
Regional Economic Strategy and regular economic bulletins (e.g. [1], [2]).
One example was the use of the Regional Accounts as the basis for the
economic evaluation and re- appraisal of the agency's priority sectors [3,
4]. In the SWRDA Legacy Documentation, SWRDA Chief Economist Nigel Jump
stated that the Accounts "... have been crucial to our understanding
of the SW economy, investment appraisal and evaluation, and framing our
views about the future." [5, p.69]. Several Local Authorities have
made use of the accounts [6] for impact analysis and investment appraisal
(e.g. Somerset Council's 2011 Economic Strategy [7]). The Stockholm
Environment Institute at the University of York used the Regional Accounts
for carbon foot-printing of key sectors in the region [8, p.6].
The research has made an important contribution to the development of
Plymouth's Low Carbon Action Plan. In 2010 Plymouth City Council (PCC)
received funding for a government Low Carbon Framework pilot scheme. The
report The Low Carbon and Environmental Goods and Service Sector
(2011) [9] was the first detailed study of the nature and extent of the
local LCE and was based on an adapted form of the IO model with a low
carbon sector [10]. Hence it built upon and extended previous research
conducted by the group.
The final report ".... provided the baseline detail against which low
carbon economic targets could be considered." [11 p14], the
definition of the Low Carbon Economy adopted by the PCC for future policy
[11, p13] and underpinned recommendations in the Action Plan including
that the Low Carbon sector should be a priority sector in the Local
Economic Strategy [11, p19]. An evaluation of the Plymouth pilot for the
Department of Energy and Climate Change by CAG consultants concluded that
the project "...demonstrates the benefits gained from working with
local academic institutions." In particular: "The research
.....could be a useful comparator for other councils. It also suggests
actions for policy makers that may be transferable." [12, p.134]
During 2013 Bishop and Brand undertook a project for South West Water
(SWW) comprising two elements: a report on the Economic Drivers of Bad
Debt in the Water Sector and The Economic Impact of South West
Water on the Devon and Cornwall Economy [13]. The bad debt
report built upon recent academic papers on consumer insolvency by Bishop.
The project involved developing a bespoke input-output model of the SWW
company area, constructed using the same accounting principles as the
South West Regional Accounts, hence directly building on prior research.
In addition, a modelling tool was developed to enable the company to
update the impact assessment and conduct scenario planning. Evidence of
impact comes from a statement by Iain McGuffog [14]. The RED Group's
expertise in regional modelling is evidenced by its recent appointment
(2012) as the Department for Business Innovation and Skills, Business and
Economic Intelligence Expert in the South West [15]. This involves the
group in providing regular monthly briefings on the South West economy to
The National Institute of Economic and Social Research (NIESR).
