We Compare Values of Time Obtained with Linear Utility Functions Used in Logit and Hierarchical Logit Specifications of a 9-Mode Passenger Choice Model Estimated with Disaggregate Data From Santiago, Chile, and Find That They Are Sensitive to the Specification Used, Unconvincingly High, and...

Low-carbon hydrogen is a promising option for energy security and decarbonization. Cooperation is needed to ensure the widespread use of low-carbon energy. Cooperation among hydrogen supply chain (HSC) agents is essential to overcome the high costs, the lack of infrastructure that needs heavy...

Stochastic frontier models commonly assume positive skewness for the inefficiency term. However, when this assumption is violated, efficiency scores converge to unity. The potential endogeneity of model regressors introduces another empirical challenge, impeding the identification of causal...

Our research aims to reveal the key social, economic, and other factors behind the common fertility trends of the CEE countries compared to the rest of Europe over the past decades. A panel analysis was conducted to examine the main (social and economic) determinants of the total fertility rate...

A matematika tanszék rögös utat járt végig az elmúlt harminc évben, azonban mind az oktatás, mind a kutatás magas színvonalú megvalósításában ez nem volt akadály. A tan­szék történetének áttekintéséhez interjút készítettünk és ennek kapcsán beszélgettünk az...

The nucleolus offers a desirable payoff-sharing solution in cooperative games, thanks to its attractive properties-it always exists and lies in the core (if the core is nonempty), and it is unique. The nucleolus is considered as the most `stable' solution in the sense that it lexicographically...

This paper deals with the design problem of H∞ control for linear systems in finite-frequency (FF) domain. Accordingly, the H∞ norm from the exogenous disturbance to the controlled output is reduced in a given frequency range with utilizing the generalized Kalman–Yakubovic–Popov (gKYP)...

A dolgozat a közgazdasági modellezés matematikai hátterének problémáit vizsgálja. A modellezés legfőbb problémája, hogy a vizsgált jelenségek nem emelhetők ki a környezetükből, és nem lehet egyszerűsített modellel a gazdasági jelenségeket leírni, következésképpen a...
