In this paper we introduce a new predictor-corrector interior-point algorithm for solving P_* (κ)-linear complementarity problems. For the determination of search directions we use the algebraically equivalent transformation (AET) technique. In this method we apply the function φ(t)=t^2-t+√t...

The year 2020 saw the world turned upside down by the coronavirus pandemic. Countless human activities were suspended or cancelled as the virus spread across the globe. In this paper, we show how the regular season matches of Ecuador’s professional football league were rescheduled due to the...

The mixed-strategy equilibrium of the symmetric production-in-advance type capacity-constrained Bertrand-Edgeworth duopoly game has not been derived analytically over the entire range of intermediate capacities in the literature. Tasnádi (2020) constructed a symmetric mixed-strategy equilibrium...

A strukturális egyenletek módszere (SEM) népszerű többváltozós elemzési eszköz a marketingkutatások területén, mivel látens változók és a közöttük lévő kapcsolatok feltárását teszi lehetővé. A módszer két fő iránya a varianciaalapú (PLS) és a kovarianciaalapú...

Distancing policies became the primary preventive intervention during the COVID-19 pandemic. This paper estimates the effect of such interventions on the effective reproduction number (Rt) of this virus on a daily panel of 109 countries. Distancing interventions affect COVID infections...

The aim of our research is to understand and reveal the key economic, demographic, labour market, and other factors behind the common fertility trends of CEE countries in the past decades. Our main research question is what driving forces played a role in the development of the total fertility...

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...

In finitely additive exchange economies the usual definition of competitive equilibrium can result in an empty equilibrium set, and therefore one has to consider notions of ε-competitive equilibria. In this paper we investigate the relationship between two notions of ε-competitive equilibria.

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 −...
