A quest for a fair schedule: The Young Physicists’ Tournament
The Young Physicists Tournament is an established team-oriented scientific competition between high school students from 37 countries on 5 continents. The competition consists of scientific discussions called Fights. Three or four teams participate in each Fight, each of whom presents a problem while rotating the roles of Presenter, Opponent, Reviewer, and Observer among them. […]
A multi-channel interactive learning model of social innovation
We develop a new model of social innovation (SI) inspired by the multi-channel interactive learning model of business innovation. As opposed to the linear models of innovation, this model does not identify ‘stages’ of business innovation. Rather, it stresses that innovation is an interactive process, in which collaboration among various partners are crucial, as they […]
Korai és időskori halálozások különbségei Európában a 2000-es évek első évtizedében
A tanulmányban 38-41 európai ország lakosságának halálozásában tapasztalt eltérésekkel és ezek magyarázatával foglalkozom. Összehasonlítom a korai (0-64 éves kor) és az időskori (65 év felett) mortalitási rátákat alakító tényezőket betegség-csoportonként és nemek szerint a 2009. évre. Egy szűkebb mintán kitérek az elkerülhető (ezen belül a megelőzhető és kezelhető) betegségekből adódó halálozási különbségekre a 2015. évre. […]
The Equivalence of the Minimal Dominant Set and the Myopic Stable Set for Coalition Function Form Games
In cooperative games, the coalition structure core is, despite its potential emptiness, one of the most popular solutions. While it is a fundamentally static concept, the consideration of a sequential extension of the underlying dominance correspondence gave rise to a selection of non-empty generalizations. Among these, the payoff-equivalence minimal dominant set and the myopic stable […]
Finding and verifying the nucleolus of cooperative games
The nucleolus offers a desirable payoff-sharing solution in cooperative games, thanks to its attractive properties. Although computing the nucleolus is very challenging, the Kohlberg criterion offers a method for verifying whether a solution is the nucleolus in relatively small games (number of players n at most 15). This approach becomes more challenging for larger games […]
The Effects of Expanding a Neonatal Intensive Care System on Infant Mortality and Long-Term Health Impairments
We study the effects of the geographic expansion of a Neonatal Intensive Care Unit (NICU) system and a Newborn Emergency Transportation System (NETS) on neonatal and infant mortality and long-term impairments. We utilize gradual expansion in Hungary, we use administrative and census data, and we identify the effects from longitudinal variation in access, using changing […]
The Role of Place and Income in Life Expectancy Inequality: Evidence from Hungary
Using mortality registers and administrative data on incomes and population, we develop new evidence on the magnitudes and sources of life expectancy inequality in Hungary. We document considerable inequality across geographies and income groups, and show that inequality has increased between 1991-2016. We show that avoidable deaths play a large role in life expectancy […]
Mass media coverage and vaccination uptake: evidence from the demand for meningococcal vaccinations in Hungary
We estimate the effect of mass media coverage of the meningococcal disease on the uptake of meningococcal vaccinations in Hungary. Our analysis is based on administrative county-level data on vaccination purchases linked to indicators of media coverage of the meningococcal disease and to administrative records of disease incidence. Using geographical and time variations in these […]
Temperature, climate change, and human conception rates: Evidence from Hungary
In this paper, we examine the relationship between temperature and human conception rates and project the impacts of climate change by the mid-twenty-first century. Using complete administrative data on 6.8 million pregnancies between 1980 and 2015 in Hungary, we show that exposure to hot temperatures reduces the conception rate in the first few weeks following […]
Termelékenység, innováció és külkereskedelem magyar vállalati adatok alapján
Az innováció és a termelékenység közötti vállalati szintű kapcsolat elemzésekor az exporton kívül az importot is figyelembe kell venni. Az innováció pozitívan hat a termelékenységre, ugyanakkor a hatás mértéke időben változott. Az innováció termelékenységre kifejtett becsült hatása 2010-ig nőtt, utána csökkent és 2016-ra visszaesett a 2005. évi szintre. Ezt a hatást felerősítette az, hogy 2010 […]
Complexity of finding Pareto-efficient allocations of highest welfare
We allocate objects to agents as exemplified primarily by school choice. Welfare judgments of the object-allocating agency are encoded as edge weights in the acceptability graph. The welfare of an allocation is the sum of its edge weights. We introduce the constrained welfare-maximizing solution, which is the allocation of highest welfare among the Pareto-efficient allocations. […]
VERSENY ÉS SZABÁLYOZÁS 2019
A KRTK Közgazdaság-tudományi Intézetének verseny- és ágazati szabályozás kérdéskörével foglalkozó tizenkettedik kötetében elemezzük az európai „magán-versenyjog” hajnalát (Vantaa kontra Skanska ügy), a versenykorlátozó cél és hatás problémáit az uniós versenyjogban (Budapest Bank ügy) és az Európai Unió kutatás-fejlesztésre és innovációra vonatkozó állami támogatási politikáját. Több tanulmányban foglalkozunk az iparpolitika és a versenypolitika változó viszonyaival (Siemens/Alstom […]
