Recent Models and Algorithms for One-to-One Pickup and Delivery Problems

Abstract: In one-to-onePickup and Delivery Problems (PDPs), the aim is to design a set of least cost vehicle routes starting and ending at a common depot in order to satisfy a set of pickup and delivery requests between location pairs, subject to side constraints. Each request originates at one location and is destined for one other location. These requests apply to the transportation of goods or people, in which case the problem is often called the dial-a-ride problem. In recent years, there have been several significant developments in the area of exact and heuristic algorithms for PDPs. The purpose of this chapter is to report on these developments. It contains two main sections devoted to single vehicle and multi-vehicle problems, respectively. Each section is subdivided into two parts, one on exact algorithms and one on heuristics.

Counterproductive Behaviors and Psychological Well-being: The Moderating Effect of Task Interdependence

Abstract: Purpose The purpose of this study was to investigate the relationship between counterproductive behaviors (CPBs) and psychological well-being in a teamwork setting. Moreover, we examined the moderating effect of task interdependence. CPBs are considered in light of four dimensions, namely parasitism, interpersonal aggression, boastfulness, and misuse of resources.

Short-Term Gain or Pain? A DSGE Model-Based Analysis of the Short-Term Effects of Structural Reforms in Labour and Product Markets

Abstract: This paper explores the short-term effects of labour and product market reforms through a dynamic general equilibrium model that features endogenous producer entry, equilibrium unemployment and costly job creation and destruction. Unlike in existing work, the link between labour and product market dynamics and the policy factors driving it are modelled explicitly. The analysis yields three main findings. First, it takes time for reforms to pay off, typically at least a couple of years. This is partly because their benefits materialise through firm entry and increased hiring, both of which are gradual processes, while any reform-driven layoffs are immediate. Second, all reforms appear to stimulate GDP already in the short run, but some of them -- such as job protection reforms -- are found to increase unemployment temporarily. Implementing a broad package of labour and product market reforms enables governments to minimise or even alleviate such transitional costs. Third, reforms are not found to have noticeable deflationary effects, suggesting that the inability of monetary policy to deliver large interest rate cuts in their aftermath -- either because of the zero bound on policy rates or because the country belongs to a large monetary union -- may not be a relevant obstacle to reform implementation. Alternative simple monetary policy rules have little impact on the transitional costs from reforms.
