We compare the performance of maximum likelihood (ML) and simulated method of moments (SMM) estimation for dynamic discrete choice models. We construct and estimate a simplified dynamic structural model of education that captures some basic features of educational choices in the United States in...

We derive the proper form of the Akaike information criterion for variable selection for mixture cure models, which are often fit via the expectation-maximization algorithm. Separate covariate sets may be used in the mixture components. The selection criteria are applicable to survival models...

This paper uses newly collected panel data that allow for significant improvements in the measurement and modeling of IT productivity to address some long-standing empirical limitations in the IT business value literature. First, we show that using GMM-based estimators to account for the...

We econometrically evaluate information worker productivity at a midsize executive recruiting firm and assess whether the knowledge that workers accessed through their electronic communication networks enabled them to multitask more productively. We estimate dynamic panel data models of...

In dieser Arbeit entwickeln wir neue Methoden und Verfahren, um aktuelle Modellierungsverfahren zu ergänzen und zu verbessern und um so ein tieferes Verständnis von Energiemärkten zu gewinnen. Wir untersuchen verschiedene Aspekte der stochastischen Modellierung von Energiemärkten: wir...

Primarily, the study assesses the determinants of non-oil import demand in ­Nigeria. This is aimed at measuring the relative strengths and nature of effects of the variables that determine Nigeria's non-oil import demand, and subsequently assessing the extent to which results are in conformity...
