The genetic engineering techniques are essential in modern agriculture and, at the same time, demand regulation on several levels. The diffusion of planting genetically modified organisms (GMOs) has grown since 1996, notably in the United States, Argentina and Canada. In Brazil, the production...

Using a proportional hazard model with multiple exits, this paper analyzes whether immigrants' unemployment spells differ from natives', and if so, how the difference vary with time spent in Sweden and across immigrant cohorts. A unique data set taken from the Swedish unemployment registers is...

This research examines re-entry into the labour force for mothers after maternity leave. The empirical analysis focuses on the first twenty-two years of post-reunification Germany, using proportional hazards models. Results show that the re-entry into part-time employment is primarily affected...

Optimal age replacement policies for network components such as cables, overhead lines or transformers are usually identified based on gathered knowledge about the state of a component and its stochastic deterioration process. In this context, uncertainty is an important challenge because...

Academics, practitioners, and investors at large typically have a preference for making decisions based on a single variable that is supposed to be maximized or minimized. This approach is usually appropriate but it may also be misleading. When selecting an optimal retirement strategy a retiree...

Reliability has been largely applied to industrial systems in order to study the various possibilities of systems’ failure. The goal is to establish the chain of events leading to any system’s failure, namely the top event. Looking for the minimal paths leading to any system’s fault allows...

A ranking method assigns to every weighted directed graph a (weak) orderingof the nodes. In this paper we axiomatize the ranking method that ranksthe nodes according to their outflow using four independent axioms. This outflowranking method generalizes the ranking by outdegree for directed...

The present study reviews the literature about dynamic decision-making and judgment of low-probability, high-consequence events. The specific features of this situation under risk and uncertainty imply an anomaly: while the single probability of an event with high negative consequences may be...
