We investigate a simple nonlinear model of economics to which strong multiplicative noise is added, and find two distinct generic control regimes. In the regime of noisy behavior, the application of the control is able to reduce noise only if the underlying periodicity is correctly taken into...

The formation of complex patterns in physical or biological systems is often caused by the interaction of many low (Kolmogorov) complexity systems, leading to emergent collective effects. In this contribution, we demonstrate how complex processing of acoustic signals by the peripheral auditory...

Household debt relative to disposable income increased from 60% in 1980 to 104% at the end of 2003. ‘Buying on credit’ has become so popular that an increasing number of firms generate more profit from financing than from selling their products. In this paper, we show that rising income...

The method Schroeder is accepted amongst real estate professionals in Switzerland as a near standard for condition monitoring, budgeting of maintenance and refurbishment, and strategic decision support in point of building portfolios. It is based on the devaluation curves of 12 or more building...

The paper revives a theoretical definition of party coherence as being composed of two basic elements, cohesion and factionalism, to propose and apply a novel empirical measure based on spin physics. The simultaneous analysis of both components using a single measurement concept is applied to...

Previous research suggests firms can build a market share advantage by preempting later entrants with a broad product line and expanding rapidly into related markets. Whether such a strategy leads to a pioneering profit advantage relative to followers also depends on its cost effects. In this...
