What Can Macroeconometric Models Say About Asia-Type Crises?.
If you are interested in this subject, you should read this paper
before reading this chapter. The paper uses the MC2 model to analyze
Asia-type crises. The four experiments in this paper can be duplicated
on this site. The following are the steps necessary to duplicate the
first experiment, the exchange rate experiment for Thailand.
Once the model is solved you can examine the results. If you have set the experiment up correctly, your comparisons (between your dataset and MC2BASE) will match the comparisons in Table 2 in the paper, subject to slight rounding error. You can, of course, examine many more variables and periods than are presented in the paper.
The notation on the website for the variables presented in Table 2 of the paper is: consumption (C), exports (EX), investment (I), imports (IM), import price level (PM), export price level in local currency (PX), export price level in dollars (PX$), domestic price level (PY), current account as a percent of nominal potential output (SPCT), and output (Y).
The other three experiment in Table 2 of the paper can be run by starting over (with a new dataset) and following the above steps, where E is changed for the country of interest. Other exogenous variables can also be easily changed.
This experiment is useful for seeing the effects of exchange rate changes in the model.
As was mentioned in Chapter 2 of this workbook, the use of the historical errors is important. This allows the perfect tracking solution to be the base path, from which changes can then be made. If you did not use the historical errors, you would have to first create a base path of predicted values, which the new predicted path (after the interest rate changes) would be compared. See Section 2.6 of The US Model Workbook for more discussion of this.
