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...

The main goal is to present two investment recommender systems (IRS), by combining clustering, factor analysis, Adaptive Neuro Fuzzy Inference System (ANFIS), and Multimodal Neural Network (MNN). The aim is to merge each method with advanced techniques to improve the precision and efficiency of...

In this paper, we propose new linearly convergent second-order methods for minimizing convex quartic polynomials. This framework is applied for designing optimization schemes, which can solve general convex problems satisfying a new condition of quartic regularity. It assumes positive...

As part of a study aimed at estimating suburban highway needs for year 2005, models were developed for forecasting daily vehicle miles of travel (DVMT) for urban areas and its distribution by highway functional class, urban location, and urban area size. A regression model combining both time...

Cikkünk a fogyasztói márkaérték meghatározása során az okozati illetve reflektív mérési modellek problematikájából indul ki. Véleményünk szerint a márkaérték meghatározására használt strukturális egyenlet modellek becslésének csak akkor van létjogosultsága, ha ezek a...

A társadalmi problémák és konfliktusszituációk jelentős része elosztási kérdésekre vezethető vissza. A vizsgálat tárgya kiterjed például lakóközösségek közös költségének felosztására, örökösök közötti osztozkodásra, csődbement cég vagyonának...

In this paper we analyze criminal deterrence in the presence of specific psychic costs of punishments. We consider a dynamic model with three players, analyzing the choices of a representative lawmaker, potential criminal and judge. In our setting the lawmaker decides whether to introduce a...
