Hello The answer is yes -- explanatory variables can have identical values for each cross-section.

If you are using the POOL command for estimation the data for each cross-section is stacked one after another. The exchange rate variable will have the same 13 numbers repeated for each cross-section.

If you are using the SYSTEM command for estimation then a set-up may specify one equation for each cross-section. Each equation will have the same variable name for the interest variable in the list of explanatory variables. Diana Whistler University of British Columbia
