Apples and oranges? A comparison of the public expenditure of the Visegrád countries

In this article, the average expenditure of Hungary is compared to that of the other three Visegrád countries. In Hungary, this expenditure is higher by 10 % of GDP, but one-quarter of this is attributable to higher interest expenses, and one-third to revenue factors which simultaneously increase both revenues and expenses. These revenue factors have a neutral impact in terms of the deficit, but they distort the comparison in respect of the levels of expenditure. For example, the tax content of public expenditures, the sales and fee revenues collected directly to cover the expenditures, and the size of EU subsidies – flowing through the budget – vary considerably from one country to the next. Two-thirds of the remaining 4-percentage point difference appears in relation to households’ cash transfers (pensions, family allowances). Hungary spends more on public services and economic subsidies, but less on the current and capital expenditure of healthcare institutions.government expenditure, public spending, Visegrad countries.

Superdiffusion in a class of networks with marginal long-range connections

A class of cubic networks composed of a regular one-dimensional lattice and a set of long-range links is introduced. Networks parametrized by a positive integer k are constructed by starting from a one-dimensional lattice and iteratively connecting each site of degree 2 with a $k$th neighboring site of degree 2. Specifying the way pairs of sites to be connected are selected, various random and regular networks are defined, all of which have a power-law edge-length distribution of the form $P_>(l)\sim l^{-s}$ with the marginal exponent s=1. In all these networks, lengths of shortest paths grow as a power of the distance and random walk is super-diffusive. Applying a renormalization group method, the corresponding shortest-path dimensions and random-walk dimensions are calculated exactly for k=1 networks and for k=2 regular networks; in other cases, they are estimated by numerical methods. Although, s=1 holds for all representatives of this class, the above quantities are found to depend on the details of the structure of networks controlled by k and other parameters.Comment: 10 pages, 9 figure

Partially asymmetric exclusion models with quenched disorder

We consider the one-dimensional partially asymmetric exclusion process with random hopping rates, in which a fraction of particles (or sites) have a preferential jumping direction against the global drift. In this case the accumulated distance traveled by the particles, x, scales with the time, t, as x ~ t^{1/z}, with a dynamical exponent z > 0. Using extreme value statistics and an asymptotically exact strong disorder renormalization group method we analytically calculate, z_{pt}, for particlewise (pt) disorder, which is argued to be related to the dynamical exponent for sitewise (st) disorder as z_{st}=z_{pt}/2. In the symmetric situation with zero mean drift the particle diffusion is ultra-slow, logarithmic in time.Comment: 4 pages, 3 figure

Pulsating B-type stars in the young open cluster h Persei (NGC 869)

We announce the discovery of six Beta Cephei stars and many other variable stars in the young open cluster h Persei (NGC 869). The cluster seems to be very rich in variable B-type stars, similarly to its twin, Chi Persei (NGC 884).Comment: 5 pages, 5 figures, Proc. HELAS-II conference, Goettingen, 20-24 August 200

Comparison of the Redistribution Level and Structure of Functional Expenditure in the Visegrád Countries

Our study aims to compare the level of redistribution, and expenditure structure of the Visegrád countries in the period between 1995–2010. For the purpose of comparability, the new methodology presented in the study filters out those components of total expenditures, which are exogenous in the short term from the perspective of economic policy makers. Of these, the most significant are the interest payments determined by the level of indebtedness and interest rates, tax payments within the general gov-ernment, and EU subsidies running through the budget. Beyond this we defined a structural indicator for medium term expenditure developments, which filters cyclical effects from the corrected data, and also spreads the government’s capital expenditures out with-in the electoral cycle. The disaggregated figures highlight that compared to the other countries of the region, the excessive level of expenditure was increased by the growth of social expenditures in the period between 2002–2006 in Hungary. Afterwards, cuts were made to the additional expenditure by reducing public health care and general public services expenditure. The total adjusted Hungarian expenditure level fell short of the regional average in 2010. At the same time, Hungary had the highest level of social expenditures and the lowest level of healthcare expenditures in the region

Dynamics at barriers in bidirectional two-lane exclusion processes

A two-lane exclusion process is studied where particles move in the two lanes in opposite directions and are able to change lanes. The focus is on the steady state behavior in situations where a positive current is constrained to an extended subsystem (either by appropriate boundary conditions or by the embedding environment) where, in the absence of the constraint, the current would be negative. We have found two qualitatively different types of steady states and formulated the conditions of them in terms of the transition rates. In the first type of steady state, a localized cluster of particles forms with an anti-shock located in the subsystem and the current vanishes exponentially with the extension of the subsystem. This behavior is analogous to that of the one-lane partially asymmetric simple exclusion process, and can be realized e.g. when the local drive is induced by making the jump rates in two lanes unequal. In the second type of steady state, which is realized e.g. if the local drive is induced purely by the bias in the lane change rates, and which has thus no counterpart in the one-lane model, a delocalized cluster of particles forms which performs a diffusive motion as a whole and, as a consequence, the current vanishes inversely proportionally to the extension of the subsystem. The model is also studied in the presence of quenched disordered, where, in case of delocalization, phenomenological considerations predict anomalously slow, logarithmic decay of the current with the system size in contrast with the usual power-law.Comment: 24 pages, 13 figure
