Sales force management decisions belong to the major issues considered in marketing research. Among others, the alignment of sales territories has been one of the main field of work for years. Recent results have reported a strong impact of the alignment of sales territories on profit, and,...

Recently, Branzei, Dimitrov, and Tijs (2003) introduced cooperative interval-valued games. Among other insights, the notion of an interval core has been coined and proposed as a solution concept for interval-valued games. In this paper we will present a general mathematical programming algorithm...

In this work, inspired by Winter (2006), in fact of vintage 1968, we discuss the relation between three different levels of analysis of technologies, namely as (i) bodies of problem-solving knowledge, (ii) organizational procedures, and (iii) input-output relations. We begin by arguing that the...

Incentives often fail in inducing economic agents to engage in a desirable activity; implementability is restricted. What restricts implementability? When does re-organization help to overcome this restriction? This paper shows that any restriction of implementability is caused by an identifi...

Using a standard production model, we demonstrate theoretically that, even if labor is fully flexible, it generates a form of operating leverage if (a) wages are smoother than productivity and (b) the capital-labor elasticity of substitution is strictly less than one. Our model supports using...

Linear optimization problems are investigated whose parameters are uncertain. We apply coherent distortion risk measures to capture the violation of restrictions. Such a model turns out to be appropriate for many applications and, principally, for the mean-risk portfolio selection problem. Each...
