Jacek BEDNARZ 1 Stanisław GĘDEK 2 PŁYNNOŚĆ JAKO CZYNNIK RYZYKA NA RYNKU KAPITAŁOWYMW opracowaniu przedstawiono modelowe ujęcie płynności jako czynnika ryzyka w warunkach rynku kapitałowego. W przedstawionej analizie wykazano, że uwzględnianie egzogenicznej płynności rynku jako elementu ryzyka w wypadku instytucjonalnie zarządzanych portfeli aktywów ma nie tylko charakter behawioralny. Wykazano również, że całkowita użyteczność portfela zależy od preferencji inwestora względem ryzyka płynności. Słowa kluczowe: czynnik ryzyka, rynek kapitałowy.
Regions specialized in the organic milk production in Poland represent a small share in the total production of this raw material within the country. Measurement of concentration is one of the key issues in research on the economic structures of market phenomena. The aim of the work was to examine the degree of concentration of the organic milk market in the context of the total milk market, as well as an attempt to answer the question about the possibility of indicating regions specializing in the production of organic milk. The study was carried out using the classical Herfindahl-Hirschman index. A modified version of the formula of the zero unitarization method was also used. The obtained results indicate a moderate degree of concentration of the organic milk market. At the same time, using the modified zero unitarization method, it is possible to clearly identify regions in which the production of organic milk has more economic significance.
This article shows a brief perspective on the timeline between knowledge and innovation management and what is now known as Knowledge Intensive Business Services, where knowledge management has a leading role in the establishment of a competitive advantage in business organizations, a strategy that will allow them to reflect their competitiveness in a changing environment by mastering their innovation competence. This implies that knowledge management has both an inherent part of organizations of the post-industrial era and a strong need to respond to the challenges brought by today's society. Such a relatively new way of doing business dictates significant changes to be made in businesses, starting with their human capital as the key element and asset.
The interest rate curve is often viewed as the leading indicator of economic prosperity in a broad sense. This paper studies the ability of the slope of the yield curve in the term structure of interest rates to impact the sectoral indices on the Warsaw Stock Exchange, using daily data covering the period from 1 January 2001 to 30 September 2020. The results of the research indicate an ambiguous dependence of the logarithmic rates of return of sub-indices on the change of the interbank interest rate curve. The only sectors showing a clear relationship of this type is energy and pharmaceuticals.
