Promotions are at the same time beloved and feared by both food retailers and branded goods manufacturers in today's retail environment. Beloved because they attract smart customers and generate an immediate effect on a brand's sale. Feared because there is uncertainty about the competitors' behavior and the actual customer demand leading to high forecast errors. For the retailer, this results in a doom loop of over- or understocking with high inventory costs in the supply chain. Collaboration between retailers and the manufacturer disentangles the doom loop. The thesis reveals the...

The presented work combines two areas of research: cooperative game theory and lot size optimization. One of the most essential problems in cooperations is to allocate cooperative profits or costs among the partners. The core is a well known method from cooperative game theory that describes efficient and stable profit/cost allocations. A general algorithm based on the idea of constraint generation to compute core elements for cooperative optimization problems is provided. Beside its application for the classical core, an extensive discussion of core variants is presented and how they can be...

Artificial economics aims to provide a generative approach to understanding problems in economics and social sciences. It is based on the consistent use of agent-based models and computational techniques. It encompasses a rich variety of techniques that generalize numerical analysis, mathematical programming, and micro-simulations. The peer-reviewed contributions in this volume address applications of artificial economics to markets and trading, auctions, networks, management, industry sectors, macroeconomics, and demographics and culture.

The authors draw from the theory of cointegration in order to test the monetary model of exchange rate determination. They focus on the issue of optimal prediction in partially non-stationary multivariate time series models. In particular, they carry out an exchange rate prediction exercise.

The three major aims of the present study were to (a) test some of the major game-theoretic solutions for n-person games in characteristic function form with data obtained from "rational" players; (b) locate, assess, and explain differences between sophisticated and naive subjects in coalition frequencies and payoff disbursements; and (c) provide a common data base for bargaining process analyses and testing of both present and future models. To this end, five quartets of subjects each partici pated in 16 different coalition formation tasks presented as computer-controlled, four-person,...

In a wide number of economic problems the equilibrium values of the variables can be regarded as solutions of a parametrized constrained maximization problem. This occurs in static as well as dynamic models; in the latter case the choice variables are often paths in certain function spaces and thus can be regarded as points in infinite dimensional spaces. It is sometimes possible to determine qualitative properties of the solutions with respect to changes in the parameters of the model. The study of such properties is often called comparative statics; [15], [2], and [10]. Certain comparative...

Die vorliegende Arbeit befasst sich mit den Problemkreisen der Standortwahl und der Tourenplanung.
