Radio spectrum is a vital asset and resource for mobile network operators. With spectrum in the 800 and 900 MHz bands coverage can be provided with fewer base station sites compared to higher frequency bands like 2.1 and 2.6 GHz. With more spectrum, i.e. wider bandwidth, operators can offer...

Financial services are characterised by the integration of customers while the service is being delivered. This integration leads to interruptions and thus delays in the processing of a customer order until for example the customer provides the missing input. Because customer behaviour can only...

Cartel detection is usually viewed as a key task of either competition authorities or compliance officials in firms with an elevated risk of cartelization. We argue that customers of hard core cartels can have both incentives and possibilities to detect such agreements on their own initiative...

We document that mean earnings of managers grow faster than for non managers over the life cycle for a group of high-income countries. Furthermore, we find that the growth of earnings for managers (relative to non managers) is positively correlated with output per worker across these countries....

We document that for a group of high-income countries (i) mean earnings of managers tend to grow faster than for non managers over the life cycle; (ii) the earnings growth of managers relative to non managers over the life cycle is positively correlated with output per worker. We interpret this...

The paper shows how traditional organizational structures within the production sector, such as quality circles, learning groups ("Lernstatt") and project teams reflect the constructivist and postmodern concepts of strategic management with their wide ignorance of purely plan deterministic...
