The urgency of this research is based on the increasing focus on improving Human Development Quality (HDQ) as a primary target in West Sumatra’s Regional Development Plan for 2021–2026. The condition of human develop...

Using the result that under the null hypothesis of no misspecification an asymptotically efficient estimator must have zero asymptotic covariance with its difference from a consistent but asymptotically inefficient estim...

IntroductionThe study was conducted to respond to the growing need for standardized and comparable tools for assessing the sustainability of farms in the European Union, given that the green transition, the reform of the...

Abstract Why do foreign investors exit Central and Eastern Europe (CEE) despite formal alignment with EU institutional standards? We argue that divestment reflects not cyclical volatility but strategic responses to insti...

During the conference entitled Spatial Econometrics and Regional Economic Analyses, which took place in Lodz in 2014, there was a proposition to introduce the spatial coherence property into the Ward method, which is app...

Forest fragmentation poses a critical threat to ecosystem service functionality, particularly in rapidly urbanizing regions. This study investigates the spatio-temporal dynamics of forest fragmentation and its impacts on...

For years now, developed countries face an epidemic of high blood pressure, diabetes and high cholesterol, risk factors related to heart and circulatory disease, and a suite of psychological disorders ranging from depres...

The economic distance defines a dissimilarity level between objects functioning in the economic space. It is one of the most important issues of spatial econometrics. However its measurement is difficult due to the defin...

Abstract This study investigates the structural determinants of agricultural sustainability by analyzing the long-run effects of institutional quality, oil consumption, information and communication technology (ICT), agr...

Abstract A number of panel unit root tests that allow for cross‐section dependence have been proposed in the literature that use orthogonalization type procedures to asymptotically eliminate the cross‐dependence of t...
