Consequently, we also report the results from instrumental variables estimation (Column (3)).
The coefficient for infrastructure index from this estimation (Column 5 from Table 4 or Column 4 from Table 3) will be used in the next section to undermine the gap for Mexico.
Appendix A: Fig. 8 reports the predicted probabilities of the estimations in column (1), column (2), and column (3) of Appendix B: Table 20 (the first prediction is the benchmark that we report also in Appendix A: Fig. 6 together with the relative confidence intervals).
OLS estimations in columns 2 and 4 of Table 3 are smaller (in absolute value) compared to IV estimates, suggesting the presence of a negative bias for men and a positive bias for women.
Additionally, the resulting KLaL values for tap water were closer to the correlation of Shah et al. [1982. Design parameters estimations for bubble column reactors. A.I.Ch.E. Journal 28, 353 379] than those of other conventional models.
Focusing on the extensive margin, logit estimations presented in column (4) show that a 1.0%% increase in Seguro Popular's coverage rate reduced the probability of receiving private transfers by 0.0654 % points.
Notwithstanding these problems, estimation results in column (3) do not differ much from our previous estimates: unemployment is negatively related to absences, with a larger effect for small firm employees.
In the design of natural gas dehydration systems, correct estimation of absorption column size is crucial.
In this work the ternary distillation column estimation problem is addressed, using an ethanol-tertbutanol-water pilot experimental column.
The change is less than one times the standard error of the first-step estimation (see the column 'difference/SE' [Diff/SE]).
