Teams, in both firms and in sports, jointly produce a product. While a fixed task is assigned to each member of a team, the individual team productivity of a worker or player is difficult to conceptualize. This is particularly true, if this concept is aimed to be operable on observable data. In...

This paper contributes to the analysis of central vs. decentral (firm-level) labour market negotiations. We argue that during negotiations on a central scale employers and employees plausibly take output market effects into account, while they behave competitively during firm-level negotiations....

As argued by Ebenfeld, Mayr and Topper (2002), Onion options may be decomposed into one-touch double barrier binary options (ODBs). Using this idea, these authors provide an arbitrage-free pricing formula for Onion options within the Black-Scholes framework. Their approach rests upon solving the...

Applying a framework of perfect competition under uncertainty, we contribute to the discussion of whether or not ad valorem taxes and specific taxes are equivalent. While this equivalence holds without price uncertainty, we show that ad valorem taxes and specific taxes are almost never...

The Alchian-Allen substitution theorem states that an increase of the prices of two similar goods by the same amount leads to a relative increase in the compensated demand of the more expensive good. In this paper we generalize this theorem to ordinary demand functions and show under which...

In this paper we investigate optimal harvesting of a renewable natural resource. While in the standard approach the resource is located at a single point in space we allow for the resource to be distributed over the plane. Consequently, an agent who exploits the resource has to travel from one...

As a part of their industry or competition policies governments decide whether to allow for free market entry of firms or to regulate market access. We analyze a model where governments (ab)use these policy decisions for strategic reasons in an international setting. Multiple equilibria of this...

Applying a framework of perfect competition under uncertainty, we contribute to the discussion of whether or not ad valorem taxes and specific taxes are equivalent. While this equivalence holds without price uncertainty, we show that ad valorem taxes and specific taxes are almost never...

In this paper we investigate trade union formation. To this end we apply a model with two types of labour where both groups decide on whether they prefer to be represented by either two independent craft-specific (professional) labour unions or by a joint (encompassing) labour union. Applying...

In standard models of spatial harvesting, the resource is distributed over the complete domain and the agent is able to control the harvesting activity everywhere. In some cases, it is more realistic to assume that the resource is located at a single point and that the agent is required to...
