We consider a model of an information network where nodes can fail and transmission of information is costly. The formation of paths in such networks is modeled as the Nash equilibrium of an N player routing game. The task of obtaining this equilibrium is shown to be NP-Hard. We derive...

We consider a project scheduling problem where the precedence constraints graph is an out-tree. The processing times can be compressed by using additional resources, which causes cost and simultaneously reduces the processing times of jobs. The objective is to minimize the sum of total lateness...

In project management, the project duration can often be compressed by accelerating some of its activities at an additional expense. This is the so-called time-cost tradeoff problem which has been extensively studied in the past. However, the discrete version of the problem which is of great...

Auch wenn in fast allen Auseinandersetzungen zum Thema 'organisationaler Wandel' die Beteiligung der Mitarbeiter als erfolgskritisch deklariert wird, sind bis heute Top-down-Ansätze vorherrschend, in denen Mitarbeiter als passive Rezipienten der Reorganisation als Weisung von oben...

The question whether the adoption of International Financial Reporting Standards (IFRS) will result in measurable economic benefits is of special policy relevance in particular given the European Union?s decision to require the application of IFRS by listed companies from 2005/2007. In this...

There is a widespread consensus among the most important players in developed countries (voters, politicians, producers, traditional and green interest groups and bureaucracies) that a shift towards an eco-social market economy is essential for sustainable growth. Nevertheless, market-based...

The development of the constitution must be based on the rule of law. Direct democratic rights allow citizens to participate in the amendment process. The direct democratic process of institutional change is theoretically and empirically analyzed. A number of counter arguments and issues for a...

On the basis of abundant facility and firm-level data for German manufacturing, originating from a recent OECD-survey, this paper empirically investigates the relevance of a variety of incentives for environmentally innovative behavior of facilities, the respective influence of pressure groups,...
