A4.3 Homoscedasticity <strong>of</strong> residuals<br />
The variance <strong>of</strong> the residuals <strong>of</strong> the main empirical specification was not clearly found to be<br />
homoscedastic through a graph <strong>of</strong> residuals versus fitted (predicted) values. However, reestimation<br />
<strong>of</strong> the main empirical specification using quantile regression using heteroscedastic<br />
robust st<strong>and</strong>ard errors (presented in Section 3.5.4) revealed that the main result holds despite the<br />
above.<br />
