Our simple linear regression model illustrate what we expected: there is, even if not very strong, a
negative correlation between the Weighted Average Tariff and the total Trade in one country. One main
problem is related to R-squared that in this model is extremely low (0.09), but we think that this value in
our multi regression model will be higher. As is shown in the below chart the data is not tightly packed,
which also reflects the R-squared value. Stata Output in the Appendix.
