A company’s brand portfolio serves as its link to customers and markets, protects it from competitors, and provides it with a degree of channel power. Historically, brand portfolios were built, brand by brand. But in today’s fast-paced and highly competitive marketplace, companies cannot...

We prove the existence of a subgame-perfect epsilon-equilibrium, for every epsilon 0, in a classof multi-player games with perfect information, which we call free transition games. The noveltyis that a non-trivial class of perfect information games is solved for subgame-perfection, withmultiple...

An independence system is a family I of subsets of a ground set V with the property that any subset of any member of I also belongs to I. The inclusion-minimal sets not in I are called minimal covers. We prove several complexity results related to computation, enumeration, and counting of the...

In dit rapport wordt een economische inschatting gepresenteerd van de ontwikkeling van de kosten van beroepsziekten en arbeidsongevallen in Nederland, voor zo ver deze tot uiting komen in de schadelast van verzekeraars uit hoofde van aansprakelijkheidsverzekeringen van werkgevers....

The customer contacts taking place after a sales transaction and the services involved are of increasing importance in contemporary business models. The responsiveness to service requests is a key dimension in service quality and therefore an important succes factor in this business domain. This...

In this paper, we consider a finite set of agents with commonly known full-support priors on the fundamental space of uncertainty. Then, we show that if the hierarchies of conditional beliefs á la Battigalli and Siniscalchi (1999) are derived from these priors, then all types of the same agent...

Combinatorial optimization problems arise in several areas ranging from management to mathematics and graph theory. Most combinatorial optimization problems are computationally hard due to the restriction that a subset of the variables have to take integral values. During the last two decades...

In today’s technological environment, rapid advances have considerably increased the number of service delivery options available to companies. Consequently, in addition to the traditional network of channel intermediaries, many firms have established Customer Interaction Centers (CICs) to...

Incomplete preferences over lotteries on a ¯nite set of alternatives satisfying, besides independence and continuity, a property called bad outcome aversion are considered. These preferences are characterized in terms of their speci¯c multi-expected utility representations (cf. Dubra et al.,...

In this survey we analyze, and compare, various sufficient epistemic conditions for backward induction that have been proposed in the literature. To this purpose we present a simple epistemic base model for games with perfect information, and translate the different models into the language of...
