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

"Minimálbér-paradoxon" versenyzői munkaerőpiacon? ("Minimum-wage paradox" in a competitive labour market? Lessons from an experimental line of thought)

A versenyzői munkaerőpiac hagyományos kereslet-kínálati modellje az egyensúlyi bérszintet meghaladó minimálbér következményeként az egyensúlyi bérszint mellettinél alacsonyabb foglalkoztatást jósol; minél magasabb a minimálbér, annál alacsonyabbat. Empirikus vizsgálatok szerint ugyanakkor a minimálbér-emelés nem feltétlenül csökkenti a foglalkoztatást - ezt nevezik minimálbér-paradoxonnak -, ami legkézenfekvőbben a munkáltatók munkaerő-piaci monopszonerejével látszik magyarázhatónak. Ezzel szemben az a gondolatkísérlet, amelyről ez a cikk beszámol, általánosabb érvényű, versenyzői munkaerőpiacot feltételező magyarázat kidolgozására irányul. / === / In the conventional textbook demand/supply model of competitive labour markets, the introduction of a minimum wage above market-clearing level must reduce employment. Empirical findings suggest, however, that this may not always be the case, a finding most readily explained by monopsonistic competition in the labour market. The experimental line of thought reported here explores an alternative root, interpreting the "minimum-wage paradox" as the outcome of a competitive labour market that displays friction

A magyar minimálbér-szabályozás és hatása a foglalkoztatásra, különösen 2000-től napjainkig (Minimum-wage regulation in Hungary and its impact on employment, with particular respect to the 2000’s)

Noha az 1990-es évek első felében felbomlott az akadémiai közgazdászok sok évtizeden át örök érvényűnek hitt közmegegyezése a minimálbér szükségképpen negatív foglalkoztatási hatásáról, a túlságosan magas minimálbért minden közgazdász foglalkoztatáscsökkentő hatásúnak jósolja. Tanulmányunkban a magyar minimálbér-szabályozást e hatás szempontjából vizsgáljuk és értékeljük. / === / Although the long-held view of an unambiguously negative employment effect of a binding minimum wage was challenged by empirical findings in the early 1990’s, it is unanimously predicted that if the minimum wage is set too high it will bring about adverse employment effects. Accordingly, our study starts from an evaluation of the magnitude of the Hungarian minimum wage, i.e., of how it relates to minimum wage rates elsewhere, and of how it has developed through time. Next we inspect the main features that characterize the Hungarian system of minimum wage regulation. Theoretical views on the potential employment effect of minimum wage regulation are then surveyed and contrasted to empirical findings. The study concludes by policy recommendations. To sum up the main strand of arguments, we try to demonstrate that even though Hungary’s minimum wage, if assessed by its ratio to average and/or median full-time earnings, does not appear particularly high by international standards, it might rightly be regarded as unreasonably high in light of Hungary’s excessively low relative rate of employment among the least schooled. This diagnose should become particularly evident once one takes into account that, in sharp contrast to established rules elsewhere, a significantly higher wage floor is in effect for those with lower secondary schooling. Abolition of this legally guaranteed premium over the minimum wage as well as more moderation in minimum wage adjustments are thus highly recommended

Munkavásárlás vagy dolgozóbérlés? Elmélkedés a munkaviszony közgazdasági értelmezéséről. = Purchase of work or renting of workers?

Munkaszolgáltatások adásvételeként értelmezendő-e a munkaviszony vagy dolgozók bérléseként? A közgazdaság-tudomány álláspontja következetlen: jellemzően dolgozóbérlésnek deklarálja, ugyanakkor ideálisan munkaszolgáltatások adásvételeként gondolja el. Az írás érvelése szerint e következetlenség vélhető oka az abból fakadó szaktudományi dilemma, hogy a tömeges dolgozóbérlés színtereként értelmezett munkaerőpiac versenyzői egyensúlya elvi lehetetlenség. _______ Should the employment relationship be interpreted as a form of purchase of labour services or as one of renting workers? Economics typically portrays it as the latter, but idealizes it as the former. This apparent inconsistency can presumably be attributed to the dilemma arising from the theoretical incompatibility of the core economic concept of competitive equilibrium and the reality of mass renting of people in the labour market

Experience-earnings profile and earnings fluctuation: a missing piece in some labour market puzzles?

Drawing on data from 11 successive waves of yearly wage surveys carried out by the Public Employment Service in Hungary from 1992 to 2003, the paper examines, with the use of elementary statistical tools, whether or not earnings fluctuations differ in size across groups of employees with different degrees of schooling and labour market experience, and if they do, whether the observed differentials might be related to differences in the experienceearnings profiles of those groups. Although preliminary, our findings suggest that earnings fluctuations do differ in magnitude across those groups, and that, moreover, their magnitudes vary in positive association with group-specific global and local slopes of the relevant experience-earnings profiles. Assuming that (1) differences in the observed magnitudes of earnings fluctuations are at least partly due to differences in the flexibility/rigidity of the market rates of earnings, and that (2) flexibility/rigidity of those rates is a determinant of unemployment, it seems reasonable to expect that long-discovered systemic differences in unemployment across groups of employees with different degrees of schooling and experience (and, perhaps, across countries as well) might also be related in part to differences in experience-earnings profiles

Physiological sharp wave-ripples and interictal events in vitro: What’s the difference?

Sharp wave-ripples and interictal events are physiological and pathological forms of transient high activity in the hippocampus with similar features. Sharp wave-ripples have been shown to be essential in memory consolidation, while epileptiform (interictal) events are thought to be damaging. It is essential to grasp the difference between physiological sharp wave-ripples and pathological interictal events in order to understand the failure of control mechanisms in the latter case. We investigated the dynamics of activity generated intrinsically in the CA3 region of the mouse hippocampus in vitro, using four different types of intervention to induce epiletiform activity. As a result, sharp wave-ripples spontaneously occurring in CA3 disappeared, and following an asynchronous transitory phase, activity reorganized into a new form of pathological synchrony. During epileptiform events, all neurons increased their firing rate compared to sharp wave-ripples. Different cell types showed complementary firing: parvalbumin-positive basket cells and some axo-axonic cells stopped firing due to a depolarization block at the climax of the events in high potassium, 4-aminopyridine and zero magnesium models, but not in the gabazine model. In contrast, pyramidal cells started firing maximally at this stage. To understand the underlying mechanism we measured changes of intrinsic neuronal and transmission parameters in the high potassium model. We found that the cellular excitability increased and excitatory transmission was enhanced, whereas inhibitory transmission was compromised. We observed a strong short-term depression in parvalbumin-positive basket cell to pyramidal cell transmission. Thus, the collapse of pyramidal cell perisomatic inhibition appears to be a crucial factor in the emergence of epileptiform events

Electroconvulsive therapy in a Hungarian academic centre (1999-2010).

BACKGROUND: Since the 1930s, the Department of Psychiatry and Psychotherapy at Semmelweis University (DPPSU) in Budapest has played a leading role in convulsive therapy in Hungary. The aim of this study was to describe the pattern of ECT use at the DPPSU over an 11-year period. SUBJECTS AND METHODS: Analysis of the medical notes of all patients treated with ECT in this academic centre between 1999 and 2009. RESULTS: During the study period, 28,230 patients were admitted to the DPPSU, of whom 457 (1.6%) received ECT. More than 50% of patients receiving ECT were diagnosed with schizophrenia. The percentage of female patients receiving ECT significantly exceeded that of the male patients, above what was expected in view of the diagnostic mix. CONCLUSION: The data indicate that in the first decade of the 21(th) century, ECT use shows a declining tendency in this Hungarian academic centre. The mean number of treatment sessions was relatively low and nearly the same across diagnostic groups. ECT was mainly used as a last resort for treatment-resistant patients. In the majority of cases, bifronto-temporal brief pulse stimulation was applied. Seizures were monitored with EEG and EMG

Provenance groups in a Roman jet jewelry collection at Aquincum (Budapest, Hungary) and comparison with jet and jet-like gemstones

Jet and jet-like gemstones are found in graves from the Neolithic, but they became particularly popular during the Bronze Age and the Roman period. To discover their provenance, several techniques were used to determine distinctions between organic materials and occurrences. The present study utilized a combination of Fourier Transform Infrared spectroscopic (FTIR) and stable isotope ratio analyses to compare a unique Copper Age black bead („Lelle bead”) with Roman period jet items from the Aquincum Museum’s collection and known jet samples from various locations (UK, Spain, Turkey). Visual and multivariate statistical analyses of FTIR spectra, combined with H%, C%, and stable hydrogen and carbon isotope ratio determinations enabled us to distinguish significant (p < 0.1) groups among the Aquincum collection: „Lelle-type” samples, „Whitby-type” jets, shales, and coals. Some gemstones were positively identified as Whitby jet, whereas some of the others were indistinguishable from the Lelle bead. This study shows that the coupled FTIR and stable isotope analyses can potentially be used to determine the provenance of archaeological artifacts
