for helpful comments. We are grateful for financial support by the Austrian National Bank (Jubiläumsfonds) under Project no. 9134. Abstract We use a model of self-centered inequality aversion suggested by Fehr and Schmidt (1999) to study voting on redistribution. We theoretically identify two classes of conditions when an empirically plausible amount of(More)
Using a newly constructed panel dataset of German enterprises, I estimate R&D and capital investment equations for the time period from 1990 to 1994. Simple accelerator specifications indicate considerable sensitivity of R&D and investment to cash flow for relatively small firms. Much of this effect vanishes already once error-correcting behavior is taken(More)
and the WZB in Berlin offered a number of helpful comments. The usual disclaimer applies. ABSTRACT Previous empirical work on corporate growth rates using cross-section or short-panel econometric techniques suggests that growth rates are random but that some degree of mean reversion exists. This means that size differences between firms are transitory. We(More)
Modelling in systems biology currently lacks clinical applications. As a possible approach leading to clinical relevance the modelling of tissue homeostasis is proposed. As an example a model of epidermal homeostasis is presented which reproduces central morphological and kinetic characteristics of epidermal tissue. Each individual cell is modelled as an(More)
In this paper a novel spline-based multi-lane detection and tracking system is proposed. Reliable lane detection and tracking is an important component of lane departure warning systems, lane keeping support systems or lane change assistance systems. The major novelty of the proposed approach is the usage of the so-called Catmull-Rom spline in combination(More)
States are ill equipped to meet the challenges of a globalized world. The concept of citizenship with its rights and obligations, including the allegiance owed, is too narrowly defined to exist only between individuals and a state. Today, people identify with, and pay allegiance to, many organizations beyond the state. This paper suggests that citizenship(More)
A model-based design of systems requires appropriate tool support in many ways. It requires a modeling notation that suits the application problem, a set of analysis techniques that provide qualitative and/or quantitative results, and finally some optimization methods that help a designer to make appropriate design decisions. The challenge is to integrate(More)
In general, decision support is one of the main purposes of model-based analysis of systems. Response surface methodology (RSM) is an optimization technique that has been applied frequently in practice, but few automated variants are currently available. In this paper, we show how to combine RSM with numerical analysis methods to optimize continuous time(More)
