The accuracy of short-run macroeconomic forecasts for the UK economy i
s analysed by examining institutional, human capital and model-based f
actors. It is found that members of the Chancellor's panel of independ
ent forecasters have a superior performance than other institutions, w
hilst the higher education sector and research/consultancy organizatio
ns have detrimental records. Additionally, non-monotonic relationships
are found for the number of economists contributing to the forecast a
nd the number of equations within the model. Moreover, with respect to
the mean number of these factors currently employed by organizations
in the sample, economies of scale exist in forecast accuracy. However,
the attainment of a doctorate and the number of variables utilized re
duce forecast accuracy.
