Die meisten wissenschaftlichen Studien, die sich einer Analyse des gesellschaftlichen Problems „Armut“ widmen, untersuchen die Armutssituation in einer Periode. Da eine statische Betrachtungsweise aber nur ein unvollständiges Bild vermittelt, wird in dieser Arbeit die individuelle Dynamik von...

This paper models firm survival in Kenyan manufacturing with a particular emphasis on the effect of credit on firm resilience. The paper explores how firms coped with the challenging economic environment that prevailed in the 1990s particularly the effect of the dramatic increase in interest...

This paper explores the adoption of two agricultural technologies, how their patterns of adoption differ, and the relationship between them. The first technology, the System of Rice Intensification, has been studied previously and high rates of disadoption were observed in some areas. The second...

Interorganizational alliances are widely recognized as critical to product innovation. A notable trend is the rapid growth of new product development (NPD) alliances between large, well-established firms and small, growing firms. This dissertation is comprised of two studies on the formation and...

We adapt the Expectation-Maximization (EM) algorithm to incorporate unobserved hetero- geneity into conditional choice probability (CCP) estimators of dynamic discrete choice problems. The unobserved heterogeneity can be time-invariant, fully transitory, or follow a Markov chain. By exploiting...

In this paper, we suggest a Stata routine for multinomial logit models with unobserved heterogeneity using maximum simulated likelihood based on Halton sequences. The purpose of this paper is twofold. First, we describe the technical implementation of the estimation routine and discuss its...

This paper investigates preference heterogeneity of wine consumers by using latent class models based onattitudinal questions. Such responses turn out to be an important source of additional information when the goalis to identify different groups of people with a similar wine preference...

In dynamic discrete choice analysis, controlling for unobserved heterogeneity is an important issue, and finite mixture models provide flexible ways to account for unobserved heterogeneity. This paper studies nonparametric identifiability of type probabilities and type-specific component...

We examine the failure determinants for large quoted UK industrials using a panel data setcomprising 539 firms observed over the period 1988-93. The empirical design employs datafrom company accounts and is based on Chamberlain’s conditional binomial logit model,which allows for unobservable,...
