In a previous paper we developed a non-standard two-stage recourse model for the dynamic day-ahead paratransit planning problem. Two heuristics, which are frequently applied in the recourse model, contain many details which leads to large CPU times to solve instances of relatively small size. In...

To stimulate sales of sustainable products, retailers need to know whether their in-store instruments effectively influence their market shares. This study uses actual sales data and a multilevel modeling approach to describe the market shares of sustainable brands according to price level,...

We provide a literature overview of the linkages between Poverty Reduction Strategy Papers (PRSPs) and the Millenium Development Goals (MDGs) and use novel data to examine their relation. We find that introduction of a PRSP is associated with progress in four of the nine MDG indicators we study....

This paper uses stochastic frontier analysis (SFA) to examine whether there is a trade-off between outreach to the poor and efficiency of microfinance institutions (MFIs). Using a sample of more than 1,300 observations, our study suggests that outreach and efficiency of MFIs are indeed...

Stature is increasingly popular among economic historians as a proxy for (biological) standard of living. Recently, researchers have started branching out from written sources to the study of stature from skeletal remains. Current methods for the reconstruction of stature from the skeleton...

This paper introduces a general, formal treatment of dynamic constraints, i.e., constraints on the state changes that are allowed in a given state space. Such dynamic constraints can be seen as representations of "real world" constraints in a managerial context. The notions of transition,...
