This paper produces a comprehensive assessment of income redistribution to the working-age population, covering OECD countries over the last two decades. Redistribution is quantified as the relative reduction in market income inequality achieved by personal income taxes (PIT), employees’ social security contributions, and cash transfers, based on household-level micro-data. A detailed decomposition analysis uncovers the respective roles of size, tax progressivity, and transfer targeting for overall redistribution, the respective role of various categories of transfers for transfer redistribution; as well as redistribution for various income groups. The paper shows a widespread decline in redistribution across the OECD, both on average and in the majority of countries for which data going back to the mid-1990s are available. This was primarily associated with a decline in cash transfer redistribution while PIT played a less important and more heterogeneous role across countries. In turn, the decline in the redistributive effect of cash transfers reflected a decline in their size and in particular by less redistributive insurance transfers. In some countries, this was mitigated by more redistributive assistance transfers but the resulting increase in the targeting of total transfers was not sufficient to prevent transfer redistribution from declining.

European countries have the world’s most redistributive tax and transfer systems. While they have been well equipped to deal with vertical inequality – fostering redistribution from the rich to the poor – less is known about their performance in dealing with horizontal inequality, that is, in redistributing across socioeconomic groups. In a context where individuals may not only care about vertical redistribution, but also about the economic situation of the specific groups they belong to, the horizontal dimension of redistribution becomes politically salient and can be a source of social tensions. The authors analyse the performance of the 28 EU countries for redistribution across (i) age groups; (ii) occupational groups; and (iii) household types over the period 2007–2014 using counterfactual simulation techniques. We find a significant degree of heterogeneity across countries: changes in the tax and transfer system have particularly hit the young and the losers of occupational change in Eastern European countries, while households with greater economic security have benefited from these changes. The findings of this study suggest that horizontal inequality is a dimension which policy-makers should take into account when reforming tax and transfer systems.

The purpose of this paper is to investigate the adjustment of government redistributive policies in Scandinavian and Mediterranean countries following changes in income inequality over the period 1980–2021.

The authors first modelled the time-varying dynamics between income inequality and redistribution and then used a non-linear framework to test for the existence of asymmetries and cointegration in their long-run relationship. The authors used two complementary measures of inequality – the share of total income accruing to top percentile income holders and the ratio of the share of total income accruing to top decile income holders divided by that accumulated by the bottom 50% – and computed redistribution as the difference between the two inequality indicators before and after taxes and transfers.

The authors found that the sign of the relationship between income inequality and redistribution is mostly positive and time-varying. Overall, the authors also found evidence that the impact of increases in inequality on redistributive measures is higher than that of decreases. Finally, the authors obtained a significant long-run relationship between both variables in all countries except Denmark and Spain. These results hold for both Scandinavian and Mediterranean countries.

To the best of the authors’ knowledge, this is the first paper to account for the potential existence of non-linearities and to examine the asymmetries in the adjustment of redistributive policies to increases in income inequality using alternative income inequality metrics.

This paper aims to re-examine the impact of government expenditure on income inequality. Existing studies provide mixed results on whether government expenditure reduces or increases income inequality. In this paper, government expenditure is viewed as a tool for redistribution, hence, its impact on inequality is examined.

A sample of 122 countries with 91 and 31 countries categorized as developing and developed countries is used. The dynamic panel threshold regression is used to examine the impact of government expenditure on income inequality and to estimate the turning point of the negative or positive effects.

The major findings suggest that, in general, government expenditure does reduce income inequality. Results from developed countries support the inversed U-shaped Kuznet curve where higher government expenditure initially led to more inequality but would eventually bring about a positive effect after a certain threshold level. For developing countries, education and development expenditure were the driving forces towards lower income inequality.

Several policy implications can be derived from this paper. First, government expenditure is a useful tool to alleviate the problem of income inequality. More integration with the global economy via trading activities is also an important channel to help reduce income inequality. Finally, better institutional quality provides an effective ecosystem in promoting better redistribution of income via government expenditure.

This paper presents a maiden attempt to estimate a threshold value or when government expenditure starts to reduce or increase income inequality. The sample is segregated into developed and developing countries to further control the effect of government size and the level of development of a country.

The recent increase in economic inequalities in many countries heightened the debates about policy preferences on income distribution. Attitudes toward inequality vary greatly across countries and numerous explanations are offered to clarify the factors leading to support for redistribution. The purpose of this paper is to examine the link between subjective social class and redistributive demands by jointly considering the individual and national factors. The author argues that subjective measures of social positions can be highly explanatory for preferences about redistribution policies.

The author uses data from 48 countries gathered by World Values Survey and empirically tests the impact of self-positioning into classes by multilevel ordered logit model. Several model specifications and estimation strategies have been employed to obtain consistent estimates and to check for the robustness of the results.

The findings show that, in addition to objective factors, subjective class status is highly explanatory for redistributive preferences across countries. The author also exhibits that there is interaction between self-ranking of social status and national context. The author’s estimations from the multilevel models verify that subjective social class has greater explanatory power in more equal societies. This is in contrast to the previous studies that establish a positive link between inequality and redistribution.

The paper contributes to the literature by introducing subjective social class as a determinant. Self-ranked positions can be very relieving about policy preferences given the information these categorizations encompass about individuals’ perceptions about their and others’ place in the society.

We investigate the role of fiscal policy, through several measures of government revenues and expenditures and redistribution, on disposable and market income inequality and economic growth as well as the interaction between inequality and growth for 31 European countries from 1995 to 2019.

We use a simultaneous equations model to assess the linkage between economic growth, inequalities and fiscal policy variables.

(1) While disposable income inequality has a negative effect on all fiscal policy variables, market income inequality has a mixed effects; (2) for Eastern European countries, public consumption and direct taxation positively influence economic growth; conversely, for Western European countries, the effects are negative; (3) disposable and market income inequality have a positive effect on growth for Eastern European countries, and a negative influence on growth for Western European countries; (4) growth contributes to the increase of disposable and market income inequality for Eastern European countries; for Western European countries, the effects are opposite; and (5) fiscal policy allows for the attenuation of disposable income inequality.

The different results between the role of market and disposable income inequality levels lead us to suggest tax progressivity as an important feature to consider when analyse the trivariate relationship between inequalities, fiscal policy and growth. Furthermore, there are different dynamics between inequality and growth, and the role of fiscal policy, on both Eastern and Western European countries.

As elsewhere, inequality has increasingly been on the agenda in recent years in Denmark, which has led to discussion about the redistributive role of welfare states across existing welfare regimes. Perhaps surprisingly, the Danish debate on inequality has revolved more specifically around how the country's tax system influences labour supply, especially the high level of marginal income taxation. The debate on poverty and inequality has become more prominent in Denmark in recent years, with a focus on the living standards of pensioners and children as well as the dynamic relationship between inequality and social policy. Thus, if there is a willingness to reduce inequality, a central challenge is to determine which instruments are available to counter rising inequalities in Denmark. In this context, the interaction between the issue of poverty and political support for specific social policies in Denmark is a challenge. Overall, the analysis suggests that tax reforms focusing on labour market supply have helped increase inequalities, thus indicating a possible trade-off between different aspects of welfare state development. Furthermore, the universality of the Danish model might be questioned in the coming years, which might also imply a debate on the generosity of a number of social security benefits, including those targeting the unemployed.

This study aims to determine how taxes can be used to bridge income inequality gap in sub-Saharan Africa (SSA).

A panel data set of 36 SSA countries was analysed using generalised method of moments.

The results suggest that an increase in direct taxes relative to indirect taxes has a positive significant impact on income inequality. This is mostly due to the progressive nature of direct taxes as compared to indirect taxes.

This research contributes to the scant literature on how specific tax components affect income inequality, especially in developing countries.

The purpose of this paper is to define economic security as a country's ability to redistribute incomes through a strong governance structure by practicing rule of law, eliminating corruption and a government that acts as a facilitator by formulating effective fiscal and monetary policy and regulation.

The paper uses two stage instrumental analysis and carries out second order asymptotic tests to establish the validity of the instruments.

The results suggest that courts that implement national laws effectively and punish corruption and a government that has balance budgets and investment friendly monetary policy ensures economic security by means of welfare friendly outcomes that favor the incomes of the poor and middle class. There is also evidence that redistribution takes place from rich to the poor. As a result, income and wage inequalities fall down.

The paper adds to the literature on institutions by providing empirical evidence on the relationship between institutions and inequality.

This chapter investigates to what extent the tax and transfer systems in Europe protect households at different income levels against losses in current income caused by economic downturns like the present financial crisis. We use a multi-country microsimulation model to analyse how shocks on market income and employment are mitigated by taxes and transfers. We find that the aggregate redistributive effect of the tax and transfer systems increases in response to the shocks. But the extent to which households are protected differs across income levels and countries. In particular, there is little stabilization of disposable income for low-income groups in Eastern and Southern European countries.
