We study the efficient computation of power indices for weighted voting games with precoalitions amongst subsets of players (reflecting, e.g., ideological proximity) using the paradigm of dynamic programming. Starting from the state-of-the-art algorithms for computing the Banzhaf and...

In this note, we apply weighted hierarchical games of cooperative game theory to the problem of optimal firm size of the firm. In particular, we analyze the influence of production technology on the size of the firm. Our note enhances previous approaches using a permission structure with equally...

The paper unveils the market structure of container shipping, which suffers by many interpretations. Existing models regress between contestability, duopoly, monopolistic competition and game theory. This paper proposes an oligopoly model with two groups of companies: oligopolists and...

In this paper, we use a partition function form game to analyze cartel formation among firms in Cournot competition. We assume that a firm obtains a certain cost advantage that allows it to produce goods at a lower unit cost. We show that if the level of the cost advantage is "moderate", then...

Individual contributions by infringing firms to the compensation of cartel victims must reflect their 'relative responsibility for the harm caused' according to EU legislation. Several studies have argued that the theoretically best way to operationalize this norm is to apply the Shapley value...

We consider a (pure) public goods provision problem with voluntary participation in a quasi-linear economy. We propose a new hybrid solution concept, the free-riding-proof core (FRP-Core), which endogenously determines a contribution group, public goods provision level, and how to share the...

The issue of capital structure of companies is one of the most debated problems of financial management. According to economic theory, capital structure determines the stock market value of firms and therefore their viability, while one of the most negative result of the crash of 2008 and the...

This paper investigates the effect of freight transport time savings (FTTS) on the performance of transport consuming companies. In the first part existing methods on FTTS valuation are critically discussed and their limitations are identified. Following, a conceptual model is built introducing...

Über die Einführung einer Pkw-Maut wird nach der Bundestagswahl heftig diskutiert. Ferdinand Dudenhöffer macht den Vorschlag, die Maut zu nutzen, um damit das gesamte Verkehrssteuersystem zu modernisieren. Sowohl die Schadstoffbelastung als auch die Staugefahr könnte auf diese Weise gelenkt...
