Long before Poland̛s accession to the European Union, the prices of agricultural land were of interest not only to potential investors in the agri-food sector, but also to speculators, whom agroeconomists were tasked with monitoring. The aim of this study was to assess changes in agricultural land prices in Poland compared to the European Union and to identify variables that strongly depend on the average level of prices of agricultural land in the European Union. This article also demonstrates that in EU countries there is a significant correlation between agricultural land prices and the value of direct payments and the value of gross domestic product per capita.

Prices are considered to be an only, directly observable market parameter, deciding on a degree of implementation of functions of market entities. The variability is inherent to prices, in accordance to an attribute of functioning on competitive market. Examination of factors affecting the prices is particularly significant on account of occurrence of many potential variables which may impact their levels and still increasing market ties among particular economies. Potato is one of the basic agricultural raw materials in the world. Potato is of high economic value, mainly through the universal usability both by manufacturers as well as consumers. The purpose of the article was to determine of variables characterizing strong dependency on evolving level of potato prices in the EU countries. Attempts of building a model aimed at depicting potato prices evolution in the European Union countries under an influence of particular variables was performed using panel data models. Conducted analyses allowed to indicate the occurrence of regional variation of potato prices in particular European Union countries. It was also shown that essential impact on a potato prices level is potato production volume, value of gross domestic product and potato import volumes.

The purpose of the paper is to analyse the impact of Industry 4.0 on employee competencies and labour market changes. It is pursued with the research hypothesis that Industry 4.0 affects how employee competencies are shaped today. The original research was based on expert literature and statistical analysis of reported data. The survey involved 154 representatives of nine sectors. The questionnaire was intended mainly for businesses that employ modern technologies. The relationships were analysed using the Spearman's rank correlation coefficient. The research leads to the conclusion that the most in-demand competencies in the modern economy are prompt action, logical thinking, team player skills, and ability to change. At the same time, engineering diploma and technical education, project management skills, and ability to work in a multi-generational environment have lost their importance. It has been demonstrated that most sectors preferred similar competencies.

Purpose – The main purpose of the work is to analyse the relationship between the net working capital management strategy and selected financial results of enterprises belonging to the WIG-food index. Research method – As part of the assessment, the financial data of 12 companies belonging to the WIG-food index for the period 2008-2018 were analysed. The dependent variables were the following measures: net profit/loss (NPL), current liquidity ratio (CLR), inventory turnover ratio (ITR), general debt ratio (GDR), return on sales (ROS). To achieve the objective of the research a one-way ANOVA variance was used. Results – The research results indicate that the net working capital management strategy adopted by the companies belonging to the WIG-Food index significantly affects the achieved financial results. Originality/value – The conducted research showed that the most common differences in shaping individual financial results occur between the use of aggressive (A) and conservative (C) strategy, aggressive (A) and moderately conservative (MC) strategy, conservative (C) and moderately aggressive (MA) strategy, as well as moderately aggressive (MA) and moderately conservative (MC) strategy.
