In early 2009 it became clear that the effects of the global financial crisis have not been
limited to the banking sector and we are now seeing major impacts on the wider economy. There
are various economic mechanisms through which the problems in banks have been transmitted
to other companies and households, such as lack of access to credit and volatility in asset
prices. This has had knock-on effects on other sectors, for example, a reduction in investment
has impact on industries that produce investment goods. Countries that have a high
concentration of such industries are particularly affected by the crisis.
There remains much uncertainty over the extent of these impacts with a relatively
wide range of forecasts, being updated when new information becomes available.
Macro-econometric models are not well-suited for the current situation as they do not include an explicit
treatment of the banking sector, where the crisis originates, while equilibrium-based modeling
approaches tend to predict a quick return to normal without providing a clear explanation of why it should be so.
This paper builds on the more theoretical analysis presented in Barker (2009), which
outlines some of the causes of the current crisis and suggests policy responses in the form of
a `seven-point plan'. The paper assesses this using an econometric model with
detailed disaggregation by sector and region. Through a series of scenarios based on assumptions
about some of the key behavioral aspects of the crisis and policy responses, a picture has been build
up of the prevailing situation in early 2009. The final result is a detailed set of
projections, disaggregated by world region and sector, incorporating both the direct and indirect effects
of these assumptions. |
