The chapter is devoted to the investigation of the relationship between slow integral
manifolds of singularly perturbed differential equations and critical phenomena in chemical …

This paper advances understanding of multiplier-accelerator interaction in European
countries in the 21st century. More than eight decades from the contributions of Keynes and …

Some recent contributions to Economic Dynamics have shown a new interest for delay
differential equations. In line with these approaches, we re-proposed the problem of the …

The question of the determination of investment decisions and their links with
economicactivity leads us to formulate a new business cycle model. It is based on the …

We consider a Kaldor-type discrete-time nonlinear business cycle model in income and
capital, where investment is assumed to depend both on the difference between normal and …

The term “canard” or “French duck” is comparatively recent in scientific literature. It has been
introduced by French mathematicians investigating van der Pol's equation [3, 5]. A trajectory …

We study the recently observed phenomena of torus canards. These are a higher-
dimensional generalization of the classical canard orbits familiar from planar systems and …

In this paper a nonlinear discrete-time business cycle model of Kaldor-type is considered, to
illustrate particular global bifurcations which determine the appearance or disappearance of …

This paper presents the bibliometrics of a Keynesian and neoclassical discussion about the
multiplier–accelerator effect. Having its oldest roots in the 1930s, there was a special …
