Abstract

This article explores the development of part-time employment in Central and Eastern Europe and compares it to Western Europe. On the macro level it examines the role of the business cycle and its effect on part-time employment in the two groups of countries since 2001. The key result reveals that contrary to the West, the business cycle development exerts a significant negative effect on the part-time employment rate in Eastern Europe. When the economy operates below its potential, part-time employment tends to grow more than full-time employment. This finding is consistent with the labour demand effect and reflects the pursuit of flexibility by firms as well as the adjustment in composition of employment to changing economic conditions. The countercyclical effect is even stronger for involuntary part-time employment. Separate analyses of individual demographic groups of workers reveal a significant negative effect of the business cycle on part-time employment of older workers and male prime-age workers in Eastern Europe. In contrast, the effect is insignificant for young workers and unclear for prime-age women.

Abstract

Interesting and challenging is not exactly that economic thinking is divided between those who admit that labour would be a good negotiated on its specific market segment and those who don’t, but other two-three aspects. The one is that those who do admit it are classic, neoclassic and (interestingly!) Marxian schools. The last thinkers certainly see it as pejorative. Interesting is equally that those who ‘reject labour market concept’ work around the Keynesian thinking school. The author of ‘General Theory…’ rejected the idea that employer and employee could ever be economically equal to each other and that labour could keep any real market supply specific behaviour. Thirdly, Keynes was the first one who pointed to unemployment as a real modern problem, but also interestingly his view on the same unemployment wasn’t satisfactory for our present.

At present, unemployment is a problem and even an unsolved one for the European economy and for the EU Organization. The EU documents might indicate it as a problem (and not only economic) and a policy priority, together with the wages issue, but basically employment and wages cannot make any policy priority against economic targets like productivity, cost reduction and industrial efficiency.

Let Ω be a bounded domain in with smooth boundary, and let 𝓧1; 𝓧2; · · ·, 𝓧m be points in Ω. We are concerned with the singular stationary non-homogenous q-Kuramoto-Sivashinsky eaquation (q-KSE:

where we use some nonlinear domain decomposition method to give a suficient condition to have a positive weak solution u in Ω under the physical Dirichlet-like boundary conditions , which is singular at each 𝓧i as the parameters λ, ϒ and ρ tend to 0 and where q ∈ [1, 4] is a real number.

Abstract

In this paper, we study the existence of positive solutions of the Dirichlet problem -Δu = λ p(x)f(u; v) ; -Δv = λ q(x)g(u; v); in D, and u = v = 0 on ∂D, where D ⊂ Rn (n ≥ 3) is an C1,1-domain with compact boundary and λ > 0. The potential functions p; q are not necessarily bounded, may change sign and the functions f; g : ℝ2 → ℝ are continuous with f(0; 0) > 0, g(0; 0) > 0. By applying the Leray- Schauder fixed point theorem, we establish the existence of positive solutions for λ sufficiently small.

Abstract

In a recent work, E. Cinti and F. Otto established some new interpolation inequalities in the study of pattern formation, bounding the Lr(μ)-norm of a probability density with respect to the reference measure μ by its Sobolev norm and the Kantorovich-Wasserstein distance to μ. This article emphasizes this family of interpolation inequalities, called Sobolev-Kantorovich inequalities, which may be established in the rather large setting of non-negatively curved (weighted) Riemannian manifolds by means of heat flows and Harnack inequalities.
