This paper models the interaction of copies and originals (e.g. MP3s and CDs, generally called flavors) in a dynamic, horizontally (stylistic variety) and vertically (distribution technology) differentiated market. The Johnson (1985) household copying model is at the root of this model. Quality...

We show that the main results of the expected utility and dual utility theories can be derived in a unified way from two fundamental mathematical ideas: the separation principle of convex analysis, and integral representations of continuous linear functionals from functional analysis. Our...

One of the basic principles of successful place marketing and branding is the thoughtful analysis of target groups needs and preferences. Many authors show favour to the city residents as the core target group. The residents may also be segmented into the smaller groups, and in some cases...

Models of labor supply derived from stochastic utility representations and discretized sets of feasible hours of work have gained popularity because they are more practical than the standard approaches based on marginal calculus. In this paper we argue that practicality is not the only feature...
