In this paper we determine the asymptotic behavior of the Non-dictatorship Index (NDI) introduced in Bednay, Moskalenko and Tasnádi (2019). We show that if m denotes the number of alternatives, then as the number of voters tends to infinity the NDI of any anonymous voting rule tends to (m −...

Social choice rules (SCRs) aggregate individual preferences to social preferences. By Arrow's (1951) impossibility theorem there does not exist a non-dictatorial SCR satisfying three desirable properties. Considering this negative axiomatic result, in this paper we determine distances of SCRs...

Social choice rules can be defined or derived by minimizing distance-based objective functions. One problem with this approach is that any social choice rule can be derived by selecting an appropriate distance function. Another problem comes from the computational difficulty of determining the...

A szavazási eljárások távolságminimalizálási problémák megoldásaiként is levezethetők. A MedRank algoritmus meglehetősen erős feltételek mellett minimalizálja a Spearman-féle colstok távolságot. Rávilágítunk ennek az eredménynek a korlátaira, és megvizsgáljuk a MedRank...

The government may regulate a market by obtaining partial ownership in a firm. This type of socially concerned firm behaves as a combined profit and social surplus maximizer. We investigate the presence of a socially concerned firm in the framework of a Bertrand-Edgeworth duopoly with capacity...

Augmented reality (AR) applications have a serious problem with the accuracy of the azimuth angle provided by mobile devices. The fusion of the digital magnetic compass (DMC), accelerometer and gyroscope gives the translation and rotation of the observer in 3D space. However, the precision is...

A pandémia időszakában felgyorsuló digitális átalakulás jelenkorunk egyik meghatározó jelensége. A tanulmány több indikátor segítségével mutatja be a hazai digitalizációs folyamat állapotát nemzetközi környezetben. A digitális eszközökkel való ellátottság területén...
