OPEN Repository

Welcome to OPEN - the Repository of Open Scientific Publications, run by the Interdisciplinary Centre for Mathematical and Computational Modelling, University of Warsaw, previously operating as the CeON Repository. The Repository enables Polish researchers from all fields to openly share their articles, books, conference materials, reports, doctoral theses, and other scientific texts.

Publications in the Repository are indexed by the most important search engines and aggregators and downloaded by users worldwide. We invite you to create an account, deposit your publications, and use the resources of the Repository.

Oszacowanie wpływu rozwoju infrastruktury na wzrost gospodarczy w świetle rachunku produktywności KLEMS
(Uczelnia Łazarskiego, 2022) Kotlewski, Dariusz; Kolegium Nauk o Przedsiębiorstwie, Szkoła Główna Handlowa w Warszawie
It is widely believed that the impact of infrastructure development on economic growth is positive. However, the controversial issue is how positive it is. This paper presents the general view of the demand-side school of economics on this topic, the view often found among neoliberal economists, and a more contemporary concept called here “sustainable” infrastructure investment. The use of KLEMS productivity accounting, a proven variant between economic growth accounting methods, is proposed as a way to study the phenomenon. A suitably modified growth decomposition model is demonstrated on the example of the aggregate Polish economy as a tool for studying the phenomenon.
Kształtowanie współczesnego bezpieczeństwa energetycznego Polski – analiza empiryczna na przykładzie rynku ropy naftowej
(Uczelnia Łazarskiego, 2022) Mróz, Maciej; Kolegium Nauk o Przedsiębiorstwie, Szkoła Główna Handlowa w Warszawie
Energy security is an important goal of Poland’s energy policy. The country’s limited resources in basic energy resources, such as crude oil, necessitate imports from third countries. The main challenges of increasing this kind of security is diversification of both sources and directions of supplies. In this case a greater scope of diversification guarantees, on the one hand, the stability of crude oil supplies, and on the other, introduces a market mechanism which determines the market price of the raw material. The aim of the publication is to analyze Poland’s energy security, taking the crude oil market in the last decade as an example. It was assumed that the stability of crude oil supplies to Poland is the result of the extensive oil infrastructure which enables the diversification of sources and directions of supplies, while the degree of acceptability of crude oil prices defines both the level and the scope of crude oil price volatility. The empirical verification of Poland’s energy security was carried out using an indicator analysis (Herfindahl-Hirschman market concentration index) and appropriate econometric models (i.e. GARCH class models).
Zmiany jakościowe infrastruktury drogowej w odniesieniu do modeli ruchu i korzyści lokalizacyjno-ekonomicznych przedsiębiorstw
(Uczelnia Łazarskiego, 2022) Brdulak, Jacek; Pawlak, Piotr; Kolegium Nauk o Przedsiębiorstwie, Szkoła Główna Handlowa w Warszawie; Instytut Transportu Samochodowego w Warszawie
The article presents qualitative changes in road infrastructure in relation to traffic modeling and assessment of the impact of this infrastructure on the location of enterprises. The development of road infrastructure also affects measurable economic benefits achieved by enterprises in connection with motor transport of manufactured products in better conditions. This issue seems to be important and still valid because motor transport is still a very important field of economy. The article briefly presents the development of traffic models, as well as the phenomena of generated traffic and induced travel in the context of traffic modeling. In the face of dynamic qualitative changes in motor transport, they should be constantly monitored. Conducting this type of analysis is necessary both in an attempt to estimate the socio-economic effects of road infrastructure development, as well as in the context of the location decision of enterprises and their transport activity. Enterprises can obtain measurable benefits related to the use of traffic models in planning optimal transport activities and selection of the most effective markets for manufactured products.
