In this paper the standard Hotelling model with quadratic transport costs is extended to the multi-firm case. The sequential game consists of a location choice stage and a price setting stage. Considering locational equilibria it is shown that neither holds the Principle of Maximum...

Tests for the cointegrating rank of a vector autoregressive process are considered which allow for possible exogenous shifts in the mean of the data generation process. The break points are assumed to be known a priori. It is proposed to estimate and remove the deterministic terms such as mean,...

Results are presented on the stability of solutions of stochastic delay differential equations with multiplicative noise and of convergent numerical solutions obtained by a a method of Euler-Maruyama type. An attempt is made to provide a fairly self-contained presentation. A basic concept of the...

In this paper we analyze the sources of German unemployment within a structural vector error correction model (SVECM) framework. For this purpose, we propose a method to estimate an exactly identified Subset SVECM, which is a SVECM with short run parameter restrictions. A cointegration analysis...

A model of herding behavior on the labor market is discussed where employers only receive signals with limited precision about the workers' types, but can observe previous employers' decisions. In particular, we study a situation where the employer and the worker can influence the signal...

The game theoretic prediction for alternating offer bargaining depends crucially on how 'the pie' changes over time, and whether the proposer in a given round has ultimatum power. We study experimentally eight such bargaining games. Each game is once repeated before moving on to the next one...

Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3. One major motivation is to test...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

MM*STAT ist ein flexibel einsetzbares Tool für Einführungskurse in Statistik im Grundstudium. Folgende konzeptionelle Überlegungen waren dabei von besonderer Bedeutung: Erstens muss die Lehrveranstaltung "Statistik" für Studenten jeder Fachrichtung ein breites Spektrum konkreter...

In the heterogeneous experimental oligopoly markets of this paper, sellers first choose capacities and then prices. In equilibrium, capacities should correspond to the Cournot prediction. In the experimental data, given capacities, observed price setting behavior is in general consistent with...
