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.

Religious Slaughter of Animals in Poland
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej, 2021) Mroczek, Robert; Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy
The aim of this study is to show various aspects related to the slaughter of cattle and poultry in Poland for religious purposes and attempt to estimate the scale of this slaughter and possible economic losses for companies in the meat and poultry industry if a ban on religious slaughter was introduced. The slaughter of animals for slaughter in Poland for religious purposes is carried out on an industrial scale and mainly concerns two species of animals, i.e. cattle and poultry. Its size can be determined only on the basis of estimates, which in the case of cattle and poultry may be 20-40% and 35-55% of the export volume, which in absolute values would correspond to 75-150 thousand tons and 500-800 thousand tons (in hot carcass weight) of beef and poultry meat, respectively. Thus, these are not small amounts. The possible introduction of a ban on the slaughter of animals for slaughter for religious purposes in Poland (with the exception of religious communities) would mean measurable financial losses for the meat and poultry industries, as well as for slaughter cattle and poultry producers. Appropriate indicators were used to determine changes over time. Descriptive and graphical analysis of statistical data was performed and a simulation calculation was made.
Factor Relations in Agriculture – Conceptual Reasoning with Empirical Verification
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej, 2021) Bezat-Jarzębowska, Agnieszka; Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy
The research presented in the paper allowed the author not only to fully recognize the correctness of production processes, but also determine the relations between production factors and production volumes (productivity and factor relations). Based on the adopted analytical assumptions and general conditions of farming processes in agriculture, the paper analyzes relations between production factors, i.e., the essence of production techniques. The research on relations between production factors is very complex, thus the paper focuses only on some areas of the issue, such as: labor productivity and its dependency on technical equipment of labor or agrarian structure (approximate land-labor ratio) and the dependency of capital-labor and land-labor ratios on production factors. The analysis is based on the principle of generality and the methodological approach for deduction is used in the paper. The empirical part of the paper uses the dataset for selected EU countries. It was concluded that the ( ) ratio, relatively to ( ) ratio, has a greater impact on the level of labor productivity. These conclusions may be significant for agricultural policy, since improving the agrarian structure does not seem to be a priority, whereas the technical equipment of labor seems to be more important. Thus, it is crucial to increase the involvement of the capital factor.
Productivity of Production Factors in Polish Agriculture and in The Selected European Union Countries with Regard to The Common Agricultural Policy Payments
(Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej, 2021) Ściubeł, Anna; Instytut Ekonomiki Rolnictwa i Gospodarki Żywnościowej - Państwowy Instytut Badawczy
The aim of the paper is to analyze the productivity of production factors of Polish and selected EU farms from 2004 to 2017, taking into account the Common Agricultural Policy (CAP) payments, based on the literature. In the postaccession period, there was a marked increase in the efficiency of production factors on Polish farms. The average land, labor, and capital productivity indices from 2004 to 2017 were EUR 442.89/ha, EUR 4,774.35/AWU, and EUR 0.25/ EUR 1, respectively. In 2014, land productivity increased to EUR 1,591.3/ha and labor productivity to EUR 11,800/AWU, amounting to 68.8% and 28.6% of the EU-28 average, respectively, while capital productivity was higher (EUR 1.41/EUR 1) compared to the EU-28 average (EUR 1.29/EUR 1). The share of CAP payments in the income of the Polish farms in 2014 increased to 49.5%; however, this was still below the EU-28 average (61.1%). Regardless of the fact that the total factor productivity (TFP) remains lower in comparison to other EU countries, the increased efficiency of Polish farms in the post-accession period should be considered as significant.
