      More precisely, we use the country-sector coefficient of variation of sales, the competition-as-major-threat dummy as well as the some-risk-of-closure dummy (for both dummies we also include the corresponding country-sector averages) and the country-sector average of the “chosen because of stable-profits” dummy.

      VAR: 9 parameters ( = 6 coefficient estimates+ 2 variance estimates + 1 Covar estimate). SVAR: 10 parameters (=8 parameters + 2 variances). It is underidentified. Sims (1980) suggested using a recursive system. For this we need to restrict some of the parameters in the VAR. Ex: assume y is contemporaneously affected by z but not vice-versa.

      One possible correction is to use coefficient of variation (cov) as a measure of the volatility. While it helps to purge the impact of the scale of the series on the measured volatility, the cov method has its own limitations. ...

      In the actual regression these variables were mainly used for quick sorting of the database, rather than to control for elimination types as was done for the chemical specific dummies. Columns BB through BH provide another set of “dummy” variables related to the age group of the children (or adults) included in each data group.
