Furthermore, the analysis lacked the data required to disentangle the two effects by using, for instance, instrumentalvariable estimation techniques. Lagged income was used as the instrumentalvariable. The only difference between the models with and without the instrumentalvariable is that the remuneration variable is only significant without the instrumentalvariable. Given the potential endogeneity of child mortality, we use the instrumentalvariable method to estimate the fertility equation. Rejection of this null hypothesis implies that at least one instrumentalvariable is correlated with the disturbance. The second issue is the double censoring of the dependent variable in equation (3), which complicates the instrumentalvariable regression. The main difference between the models with and without the instrumentalvariable is that the remuneration variable is only significant without the instrumentalvariable. Accounting for this possible bias, we use an instrumentalvariable approach. Therefore, instrumentalvariable techniques are applied when estimating (2) and (3). The results, particularly the sign and statistical significance of the coefficients, did not change with the instrumentalvariable procedures. To study the effect of selection, we will apply a particular instrumentalvariable approach. In this work, the remuneration system was endogenous, and by using an instrumentalvariable, it was found not to have a significant effect. To get unbiased and consistent estimates, we used the instrumentalvariable method to predict household expenditure per adult. Lagged income is used as the instrumentalvariable. Secondly, given the instrumentalvariable design employed here, the feedbacks between democracy, on the one hand, and investment and education, on the other, have been excluded. In table 6, the results for the double-censored model using the actual value of participation and for the double-censored model using the instrumentalvariable approach are reported. Such a strategy requires an instrumentalvariable that must be a good predictor of the first-stage dependent variable but not be correlated with the second-stage dependent variable. Also, one can ask the question of what is good inference conditional on the moments that go into the instrumentalvariable estimate instead of conditional on the whole data set. Instrumentalvariable estimation is not likelihood-principle based, but it applies to models for which there may be a likelihood. Also, traveling time (for gastroscopy) just falls short of significance when the instrumental variable is included, probably because location of the practice is included in this variable.
