Already classical economists took interest in the role of wages and wage formation mechanisms, as well as in their influence on other components of the labour market. This article aims to systematise contemporary approaches to wages as one of the labour market components that have been developed within major economic theories. The systemization will serve as a basis for identifying main interactions between wages and other labour market components, such as labour supply and demand and labour market disequilibrium. The article presents major concepts formulated within neo-classical and Keynesian theories, labour market segmentation theories, efficiency wage theory, rent-sharing and rent-extraction theories, theory of job search, and search-and-matching models. One of the conclusions arising from the discussion is that the evolution of contemporary labour markets is a challenge for researchers seeking wage formation models adequately describing the real-life circumstances.
Działalność gospodarcza opiera się na wykorzystaniu zasobów naturalnych, kapitałowych i ludzkich (społecznych). We wcześniejszych ujęciach określano je także jako tzw. czynniki wzrostu gospodarczego w postaci ziemi, kapitału i pracy. Ostatnio wyodrębnia się również technologię lub przedsiębiorczość – czyli umiejętności łączenia tych podstawowych czynników. Celem artykułu jest zaprezentowanie modelu powiązań gospodarki z naturą oraz analiza wpływu ograniczoności zasobów naturalnych na rozwój społeczno-gospodarczy w ujęciu tzw. słabej i mocnej trwałości rozwoju, z rozróżnieniem kryzysu wydobycia i kryzysu zaopatrzenia.

The paper presents a discussion on the natural resources and the conditions of their exploitation in time of scarcity of certain resources and the renewable character of others. In particular, the paper focuses on the interconnection of the economy and the environment with the application of formulae describing relationships between the primary and secondary resources, waste and consumption. Further on, the author proceeds with the presentation of the impact made by the limited resources on social and economic development along the weak and strong sustainability of development approach, making a distinction between the crisis of exploitation and the crisis of supply. In the analysis, the author used various statistical data on the production of major resources and power generation in the world, and the use of primary energy carriers in Poland.
The automotive industry is one of the most important sectors for Polish total exports and imports in terms of value, as well as the factor of trade intensity trade. The paper is aimed at verifying the hypothesis according to which the sector covered in this research does not strengthen the capital intensity of Polish exports and fosters international division of labour between centres and semi-peripheries. Thus, the issues raised here are considered in the context of the middle income trap. The author analysed trade streams in Polish exports and imports through the changes in their structure, evolution of revealed comparative advantages (RCA), import penetration (IMP), revealed advantages in trade (RTA), trade balance and the level of intra-industry trade (IIT) together with an attempt to distinguish the shares of vertical and horizontal exchange. For the purpose of the research, data at the 4- and 6-digit disaggregation level of the Harmonised System were used. As a middle income country Poland is still an attractive location for foreign investments of multinational companies. However, it may preserve the developmental gap. This may be proven by the structure of the trade in the sector covered: cars and parts and accessories of motor vehicles are the most dominant sections, which is consistent with the level of revealed comparatives advantages and revealed advantages in trade. What is also worth noticing are the trade relations with Germany, where one can easily identify a technological dependency.
