The research database consists of the OECD countries except Iceland, Latvia and Turkey, which were excluded because of insufficient data. The primary objective of the study is to group the countries according to their average wage, GDP per capita, minimum wage and unemployment rate. Another objective, of no less importance, is to determine which of the three remaining above variables significantly affect the average wage, while defining the type and strength of this relationship. Yet another important goal is to develop forecasts of the wage level and GDP per capita for each OECD country by 2020. In terms of clustering OECD countries by the four variables, the Czech Republic always ranks alongside Chile and three post-communist countries, Estonia, Hungary and Poland. GDP per capita is the only explanatory variable significantly affecting the average wage. The dependence of these two variables is represented by a second-order polynomial (concave parabola), the selected regression parabola explaining approximately 88 percent of the variability in the observed levels of the average annual wage. The conversion of the average wage, GDP per capita and minimum wage to purchasing power parity allows consideration of different price levels and thus comparison of purchasing power parity of the population in different countries.

This paper investigates the optimum saving rate from the perspective of the receivers of interest. The first part lists major contributions detected in the literature on the optimum saving rate and differential games of capitalism. The second part explores the socially optimal saving rate connected to the maximum sustainable consumption per person. A new graphical method is used to show the distribution of consumption goods between wage earners and receivers of interest. The optimum saving rate of the receivers of interest is derived in the third section. The mathematical formula indicates that this rate is lower than the golden rule, and it coincides with the optimum of the Ramsey-Cass-Koopmans model only under specific circumstances.

The aim of this article is to explore main linkages among the participation rate, potential output and pension funding system. Based on the existing literature, there are several possibilities how to render the current set-up of the pension system sustainable. This sustainability is conventionally regarded from the perspective of provision of "satisfactory level" of retirement pensions as well as from the perspective of general budgetary impact. In this respect, demographic change is accounted for owing to the common perception that it has a lot to do with how the future pension system should and will look like. It has been found out that if appropriate economic policy measures ‒ targeting mainly labour market participation rate and long-term unemployment ‒ are adopted, no need for abrupt changes in the existing social security system framework is actually necessary. Also, the linkages between the participation rate and potential output seem to be relatively strong, so that the economy could be easily considered as signifi cantly influenced by its labour market. The functioning of the latter thus seems to be pivotal for the resolution of some long-term economic capacity concerns, including its dynamics.
