On the peculiar relevance of a fundamental dilemma of minimum-wage regulation in post-socialism – apropos of an international investigation

To the extent minimum-wage regulation is effective in fighting against excessive earnings handicaps of those at the lower end-tail of earnings distribution, it may have the side-effect of worsening their employment prospects. A demand-and-supply interpretation of data on the relative employment rate and earnings position of the least educated in the EU27 suggests that the resulting dilemma might be particularly relevant for minimum-wage policies in post-socialist countries.

Effect of sampling effort and sampling frequency on the composition of the planktonic crustacean assemblage: a case study of the river Danube

Although numerous studies have focused on the seasonal dynamics of riverine zooplankton, little is known about its short-term variation. In order to examine the effects of sampling frequency and sampling effort, microcrustacean samples were collected at daily intervals between 13 June and 21 July of 2007 in a parapotamal side arm of the river Danube, Hungary. Samples were also taken at biweekly intervals from November 2006 to May 2008. After presenting the community dynamics, the effect of sampling effort was evaluated with two different methods; the minimal sample size was also estimated. We introduced a single index (potential dynamic information loss; to determine the potential loss of information when sampling frequency is reduced. The formula was calculated for the total abundance, densities of the dominant taxa, adult/larva ratios of copepods and for two different diversity measures. Results suggest that abundances may experience notable fluctuations even within 1 week, as do diversities and adult/larva ratios.

Lessons learned from the effect of tight monetary conditions and crises on corporate capital structure

The study reviews the theoretical and empirical literature on the effect of tight monetary conditions, crisis on corporate capital structure, further creates a framework for analyzing their relation, as well as sheds light on the lessons learned and open research areas. The results highlight that the supply side of capital has an effect on corporate capital structure, though the analysis of this relation is scarce. However, the impact of tight monetary conditions on capital structure is analyzed by several studies, there is limited evidence on the financial policy and the development of financing mix during a crisis period. The impact of the 2007/08 crisis on the corporate capital structure and especially in case of firms with impaired access to external financing is scarce. The study also highlights our lack in understanding of the relation of crisis and capital structure in case of the CEE region.
