Kaldor-Kalecki model is one of the first models that use non-linear functions to explain the chaotic behaviour of the economic system. Re-elaborating the model we tried to prove the existence of a Bautin bifurcation for the discrete version of the model with an adaptation of the mathematical...

The class of distortion riskmetrics is defined through signed Choquet integrals, and it includes many classic risk measures, deviation measures, and other functionals in the literature of finance and actuarial science. We obtain characterization, finiteness, convexity, and continuity results on...

In this chapter, we discuss a specific kind of progress that occurs in most branches of economics today: progress involving the repeated use of mathematical models. We adopt a functional account of progress to argue that progress in economics occurs through the use of what we call “common...

Communication is at the center of any business transaction. Unfortunately until recently, communication has rarely been assigned its proper relevance in traditional business studies at German universities. This paper attempts to demonstrate why communication science can and should be an integral...
