My dissertation research is composed of two parts: a theoretical part on semiparametric efficient estimation and an applied part in energy economics under different dynamic settings. The essays are related in terms of their applications as well as the way in which models are constructed and...

Heckman and Singer (1984) argued that in typical longitudinal analyses, standard treatments of heterogeneity components result in incorrect parameterization of the duration model. As a consequence, estimation bias is not limited to duration dependence, but extends to the structural parameters as...
