We analyze a large panel of units grouped by shared extreme value indices (EVIs) and aim to identify these unknown groups. To achieve this, we order the Hill estimates of individual EVIs and segment them by minimizing the total squared distance between each estimate and its corresponding group...

Industrial estate (IE) was established to obtain economic, territorial, and environmental advantages. A high occupancy rate indicates an IE's success, which depends on thorough IE planning and preparation. However, the literature has not fully explored a comprehensive measurement of IE readiness...

We propose a sentiment-based financial stress index (S-FSI) for Russia from January 2018 to June 2024. The index is based on the intensity of internet searches in Russian via Google and Yandex for terms with negative connotations about financial stability. The terms in our index form a unique...

Housing rents are one of the most important and difficult elements of spatial cost of living comparisons. Difficulties arise from the lack of sufficiently detailed and harmonized data, especially at the international level. The emergence of Airbnb has created a valuable new source of...

Okun's misery index (MI), the sum of unemployment rate and inflation rate, is a popular measure of the state of the economy and thus of (macro) '' Economic Discomfort'' as well as of government performance.
