The paper empirically analyzes the impact of the degree of efficiency on key performance fig-ures of publicly traded European banks in the period from 2005 to 2009. Efficiency is meas-ured by constructing non-parametric frontiers using the technique of data envelopment analysis on the cost,...

Using data from the German Socio-Economic Panel from 1984-2009, we follow persons from their working life into their retirement years and find that, on average, employed people maintain their life satisfaction upon retirement, while long-term unemployed people report a substantial increase in...

Forensic Services werden unter diesem Label in Deutschland seit gut 10 Jahren von vielen großen Wirtschaftsprüfungsgesellschaften angeboten. Da die Dienstleistungen und Methoden einzeln gesehen nicht grundlegend neu sind, stellt sich die Frage, mit welchen Vorteilen das Angebot für Anbieter...

This paper examines a principal-agent problem between a manager (principal) and an employee (agent). At the contracting date uncertainty with regard to the profitability of the relationship is present. Once the contract is signed, the employee performs a specific investment that reduces his...

We introduce transport cost of trade in products into the classical Zodrow and Mieszkowski (1986) model of capital tax competition. It turns out that even small levels of transport cost lead to a complete breakdown of the seminal result, the underprovision of public goods. Instead, there is a...

We investigate the stability of individual behavior in a repeated public good experiment over time by reinviting subjects back to the lab up to four times in one week intervals. We exclude effects due to learning about others' behavior and reputation building by employing a non-learning and...

In this paper, a problem generator for the Two-Dimensional Rectangular Single Large Object Placement Problem is presented in which the large object includes one or several defective areas. The parameters defining this problem are identified and described. The features of the problem generator...

Emission trading schemes like the European Union Emissions Trading System (EUETS) try to reconcile economic efficiency and ecological efficiency by creating financial incentives for companies to invest in climate-friendly innovations. Using real options methodology we demonstrate that under...

This paper examines the effect of uncertainty on investment timing in a game theoretical real option model. We extend the settings of Gryglewicz et al. (2008), Wong (2007), and Sarkar (2000) by a more general assumption, i.e. the investment is also influenced by the actions of a second player....

Based on a serial supply chain model with 2-periods and price-sensitive demand, we present the first experimental test of the effect of strategic inventories on supply chain performance. In theory, if holding costs are low enough, the buyer builds up a strategic inventory (even if no operational...
