Gibt es in einem räumlichen Markt einzelwirtschaftliche und/oder gesamtwirtschaftliche, wohlfahrtstheoretische Anreize zur vertikalen Integration zweier Marktstufen in einer organisatorischen Einheit (Konzern)? Zur Beantwortung dieser Frage wird ein Modell vorgestellt, in dem die Standorte der...

In this paper, we examine the movement of container freight in, out and around the third largest maritime port in the United States and the use of toll facilities by these freight movements. Understanding how road pricing affects freight activity is of significant interest to transport planners,...

We examine the extent to which uncertainty delays investment and the effect of competition on this relationship using a sample of 1,214 condominium developments in Vancouver, Canada built from 1979-1998. We find that increases in both idiosyncratic and systematic risk lead developers to delay...

Various approaches used in Agent-based Computational Economics (ACE) to model endogenously determined interactions between agents are discussed. This concerns models in which agents not only (learn how to) play some (market or other) game, but also (learn to) decide with whom to do that (or not).

Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition,...

Sustainable energy systems of the future will need more than efficient, clean, low-cost, renewable energy sources; they will also need efficient price signals that motivate sustainable energy consumption as well as a better real-time alignment of energy demand and supply. The Power Trading Agent...

The definition of emergence remains problematic, particularly for systems with purposeful human interactions. This study explores the practical import of this concept within a specific market context: namely, a double-auction market for wholesale electric power that operates over a transmission...

Natural gas is increasingly important as a fuel for electric power generation as well as other uses due to its environmental advantage over other fossil fuels. Using the World Gas Model, a large-scale energy equilibrium system based on a complementarity formulation, this paper analyzes possible...

We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in “large” partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded...

This paper explores the effectiveness of boosting, often regarded as the state of the art classification tool, in giving warning signals of recessions 3, 6, and 12 months ahead. Boosting is used to screen as many as 1,500 potentially relevant predictors consisting of 132 real and financial time...
