1. Towards a general model of economic trade, investment and growth Terry Maidment Economists Conference 2003 ANU Globalisation and Distribution MON. 13: :15 MCC T6

2. Introduction
This paper covers topics related to economic welfare from trade and growth of relevance to:
Australia,
the developing economies of ASEAN
and APEC as well as the leading industrial economies of the
United States and
Japan.

3. Story Line
Commodity price shocks applied to a GTAP simulation would quantify the effects of the recent changes relative to total global trade flows
Theory highlights the role of interest rates, exchange rates and inflation in long run ge models
The empirical model is a Keynesian demand model of consumption, IS and LM for 16 economies

4. Main points
Microeconomic foundations of investment include human capital in endogenous growth models (in particular see Beaudry and Green 2003)
At the 2003 UNSW econometric conference there were two papers on the short term official interest rate the policy instrument.
In addition, a paper on FDI observed that FDI should be placed in the context of total capital movements and complete capital markets.
An empirical result that we state is that the real exchange rate Granger causes the real interest rate but not the reverse causality in the case of Japan.

5. Finer points Special note on the EU
Policy of SLP for developing economies
Stabilisation: Argentina and Brazil
Liberalisation: APEC, WTO, China
Privatisation: EU and Budget deficit, the Maastrict Treaty

6. Regional focus and theory
CLMV (Cambodia, Laos, Myanmar, Vietnam)
APEC and MFN
ASEAN
GE Theory

7. Input Output Statistics and CGE analysis
It has been well known for some time that the statical Leontief system is the simplest form of Walrasian general equilibrium, it provides disaggregation within a macro model and in the simplest Leontief system, the linear programming solution is well defined.

8. General equilibrium assumptions

9. Sensitivity analysis and model parameters
Kim and Pagan 1997 have described calibration of CGE models as flowing from Johansen 1960.
Johansen's linearised solution of equilibrium values presupposes the existence of a benchmark data set and also an evaluation of a stochastic equilibrium solution of a potential empirically identified economy.
The solution however is not necessarily observable in a real economy.
Sensitivity to parameter values and CGE model reliability are analysed in Pagan and Shannon, 1987 and Horridge, 1986.
Hanslow and Pearson 1989 demonstrated the utility of TABLO in GEMPACK for performing local sensitivity analysis on any set of model parameters.
