The tax wedge mainly quantifies the extent to which tax on labour income enervates employment and it reflects the total labour costs. It is commonly defined as the ratio between the amount of taxes paid by the worker and the related total labour costs for the employer. As such, the tax wedge affects both the labour force (unemployment) by reflecting the burden of the employer and indirectly the household disposable income. It is conferred that the alteration caused by the tax wedge on income distribution has been analysed with a small number of empirical studies. Based on the hypothesis that the tax wedge may affect income distribution from different aspects in terms of household size and income level, dynamic panel data analysis is carried out for 36 OECD member countries and the period 2000-2019. The dynamic panel analysis estimation findings for two households (single person with no children, earning 167% of the average wage, and one-earner married couple with two children, earning 100% of average wages) reveal that the tax wedge is negatively related to unfair income distribution. In addition, the aspect of the relationship is the same (negative) for the two households.

This study aims to evaluate the effects of selected key factors on health outcomes. Unfortunately, statistical reporting in this field is not harmonized, and in some countries it is completely absent. For this reason, valuable information for health determinant analysis may be lacking or overlooked. Using two different databases, we obtained data from 61 countries for the period 2000-2015. To analyse panel data with over 660 observations, a linear mixed model was applied. This paper contributes to the health economics debate by statistically testing the relationship between health outcomes and variables such as healthcare personnel, healthcare expenditure and infrastructure. The results confirm the importance of healthcare expenditure and healthcare infrastructure. However, the size and direction of the effect vary among countries with different income levels. In regard to human resources, the number of doctors proved to have a significant effect only in lower-income countries.

This paper examines the relationship between financial stability and income inequality in 35 developing countries from 2004 to 2020 using system generalized method of mo- ments (GMM) estimation. Four dimensions of the financial sector, namely financial stability, depth, access and efficiency were included as regressors. The results for the relationship of each of the financial dimensions with income inequality are mixed. In this study, inequality increases with an increase in the stability of the financial sector; on the contrary, the depth of the financial sector reduces inequality. Furthermore, not only does the dimension of the financial sector matter in addressing income inequality issues, but the quality of institutions is important. It is important for policy makers to understand linkages between financial dimensions and inequality so as to come up with appropriate prudential regulatory mechanisms.

This study aims to investigate the impact of international remittances on income inequality in the post-communist region. The association between the variables is examined via static and dynamic panel models. Using macroeconomic data from 27 countries over the period 1991-2014, we discover that income inequality progresses along a U-shaped course as a country becomes more dependent on remittances. For most of the countries, the relationship between remittances and inequality is inverse. When remittances account for more than 20% of GDP, they exacerbate economic inequality. This finding challenges the view that remittances should only be viewed as a pro-poor redistribution mechanism because in certain cases, additional migrant transfers may actually increase income inequality.

Mancur Olson wrote his influential study Big Bills Left on the Sidewalk: Why Some Countries are Rich, and Others Poor in 1996. In his paper, Olson claimed that the differ-ences in economic development between countries are caused by only two factors: institutions and policies on the one hand and culture on the other. We attempt to test his conjecture using econometric modelling, combining and comparing it with a broadly defined orthodox production function in an indirect neoclassical notation (Solow-Minhas-Arrow-Chenery's SMAC framework). The "pseudo-production function" obtained is econometrically sound and of explanatory power similar to models including economic variables, although we find strong evidence of interdependence between capital-labour share and institutions and policies and culture. We consider the test, performed on panel data from 154 countries over five-year averages from 1980-2014, to be robust and consistent with Olson's ideas.

The present paper deals with the development of wage distribution by educational attainment in the Czech Republic in the years 2003-2012, analysing fifty wage distributions as the object of research and the gross monthly wage in CZK as the research variable. It examines the development of wage distribution in time and the gross monthly wage in relation to the level of educational attainment. It also pursues the development of the minimum wage in the monitored period. The author pays special attention to the lowest guaranteed wage levels classified according to wage classes and work capability assessment, comparing the minimum wage to the wage of subsistence. The forecasts of future wage distribution are an integral component of the research, the financial standing of Czech households being evaluated in an international context within the European Union.

A new good quality standardized data set for cross-national comparisons of income inequality covering 147 countries has been constructed. The Bayesian model averaging and multiple imputation approach have been used to identify robust correlates from a larger pool of potential predictors of cross-national variation in inequality determined from previous literature. The results document signiicant macro-regional speciicity both regarding levels and predictors of inequality. While globalization associates with lower inequality in Western countries, it has opposite e ects in Latin America, Sub-Saharan Africa or post-communist countries. Age structure, the extent of social spending, or colonial history are another important factors with regionally speciic impacts on inequality. By contrast, explanative power of some other traditional determinants of inequality has not been corroborated.

The Kuznets hypothesis of inverted U-curve dependence of the income inequality on the absolute value of the average income is still an unresolved issue despite the growing number of theoretical and empirical research on this topic. This paper analyzes the historical data on the average income and the income inequality for the period 1979-2009 collected for 145 countries. We found that the income inequality is influenced predominantly by governmental policy on subsidies and social transfers. Different amount of subsidies and social transfers across various countries makes the data biased. The inverted U-curve was found in countries with low amount of social contribution. However, increasing amount of social contributions makes the U-curve flat and shifts its maximum to higher values of the average income. Based on the experimental data a model describing the influence of both governmental policy and the level of economic development was developed.

Because of growing awareness of financial needs for public pensions, attention has been focused on privatisation of the pension systems. While the privatisation of pension funds can encourage development of capital markets in New Member States, equity investment in transition economies is even more volatile than in the ""old"" capitalist countries. Privatised pension system coincides with investment risks, higher administrative costs, and inability of private markets to provide retirees with affordable, indexed and certain annuities. Namely, private sector may not provide enough investment projects to efficiently absorb mandated pension savings and the expected pension income is subject to a number of risks: poor and volatile investment returns, longevity, and inflation eroding the purchasing power of pensions. Indeed, the PAYG system appears to be the only viable system to perform well in terms of risk and volatility of returns.

According to Abraham Maslow's motivational theory, human action is motivated by five levels of human needs. The model introduced in this paper exploits Maslow's theory to explain migration flows between regions. In the model, movement from one region to another influences migrant utility in three ways: through change in wage owing to different regional wage levels, through changes in utility connected with a migrant's safety needs, and through disarrangement of a migrant's social network. When safety and social needs are added to the model, equilibria arise in which wage differentials between regions persist.
