technology (ADUSST).3 Moreover, it is plausible that ADUSST is highly correlated with people’s previsit attitudes toward the United States, inasmuch as we would expect people who like the United States in general also to admire United States science and technology.4 We will therefore use ADUSST as an imperfect measure of respondents’ attitudes toward the United States in the absence of visiting the United States. The results of including ADUSST are shown in Table C-2.

The coefficient of USTRAVEL is positive and significant in regressions (1) and (2). Its size—0.14 and 0.10 in regressions (1) and (2), respectively—is close to the size of the coefficient of USTRAVEL in the regressions reported in Table C-1.

In regression (3), we add a term, USTRADUSST, representing the interaction of USTRAVEL with ADUSST. The coefficient of USTRAVEL is now insignificant. It is interesting that the coefficient of USTRADUSST is positive, relatively large (0.29), and quite significant. Our interpretation is that

This contention is supported by a regression (not shown) of ADUSST on USTRAVEL and various controls. The coefficient of USTRAVEL is −0.006, with a t-statistic of −0.45, suggesting that USTRAVEL indeed has little effect on ADUSST.

Of respondents who had not visited the United States, nearly everyone who has a high opinion of the United States also admires United States science and technology, and vice versa.
