Table 5b then reports on the results for the same set of experiments but where for the
exports/output, EU export share, intermediates over output, and intermediate import
share variables we have used weighted averages. As before, in the first two
regressions we include all the variables of interest. In the second two regressions we
drop the exports/output variable because we consider it to be unreliable. In the final
pair of regressions we also drop the CTH criterion.
The results are broadly highly comparable in terms of magnitude and sign to those
reported on above. However, generally the statistical significance of the results is
somewhat lower. The principle exception to this is with regard to the share of
intermediate imports by industry. Here we find that the higher is the share of
intermediate imports of a given industry typically the lower is the degree of
restrictiveness of the rules of origin. It is important to note here that out measure is the
share of intermediate imports of a given industry, and not by a given industry. For
example, we measure the amount of intermediate import of Transport Equipment for
each country, but we do not know in which industry those intermediates are then
employed. The negative coefficient on this variable thus suggests that for industries
where intermediate imports tend to be high, the degree of restrictiveness of rules of
origin tends to be low. This might suggest that the key intermediate import industries
are not those where the countries have a comparative advantage, and are thus not the
industries which the countries principally export, and where then rules of origin are
important.
