In this study, we elucidate the income redistribution effects of the proposal to incorporate the Bend Points mechanism of the U.S. OASDI into the Korean National Pension Scheme (BP-KNPS Proposal) through a micro-simulation analysis using individual data from the Korean Labor and Income Panel...

We examine the effects of patient cost-sharing on adolescents' healthcare utilization and out-of-pocket medical expenditures by exploiting the healthcare reform in South Korea that lowered the coinsurance rate for inpatient care from 20% to 5% for children under 16. We apply a...

This paper discusses the key concepts and main stylized facts concerning household real income and income inequality in the United States in recent decades. It explains the widely used summary measures of income distribution, which reveal that income inequality in the US has been steadily...

This study evaluates the incidence of food and non-food social programs in function of income inequality in households in Peru during 2022-2024 in a context of persistent distributive gaps, despite social interventions aimed at promoting equity. Data from the National Household Survey (ENAHO)...

The application of reduced VAT rates in the EU generally aims to alleviate the regressivity of consumption taxation. However, while these measures generate redistribution across income groups, they also create redistribution effects within income groups, leading to arbitrary redistribution among...

This paper describes the integration of labour supply behavioural responses into UKMOD, the UK tax-benefit microsimulation model belonging to the EUROMOD family. Traditional static models quantify only the direct ("morning after") fiscal and distributional effects of policy reforms, abstracting...

This paper assesses the fiscal and distributional effects of personal income tax expenditures in Portugal using EUROMOD and 2022 EU-SILC microdata. We compare the 2023 tax-benefit system with a counterfactual scenario in which tax expenditures are removed to estimate first-round impacts. We find...

This paper provides clear evidence that concerns for basic needs satisfaction (BNS) represent a distinct distributional motive. Using a unified theoretical and experimental framework across five dictatorgame experiments in Germany and Georgia (N=446), we disentangle BNS from motives such as...

The current report presents findings of a research project that explored attitudes towards welfare and redistributive policies among Irish residents. Public support for the welfare state is an important foundation for democratic governments to pursue the policies needed to alleviate poverty in...

Abstract We study life expectancy inequality in a Mirrleesian life-cycle framework. Life expectancy shapes the efficiency dimension of redistribution via the pension wedge. Moreover, cost- and preference-based channels arising from the income-lifespan gradient reduce the mechanical value of...

We study the distributional consequences of the recent inflationary surge and the subsequent monetary policy response in the euro area. Using an estimated two-asset Heterogeneous Agent New Keynesian model with an overlapping generations structure, we analyze the macroeconomic shocks driving...

We study the transmission and distributional effects of monetary policy in an environment where consumption-saving choices reflect both precautionary motives and life-cycle considerations. Age emerges as a key state variable linking multiple dimensions of heterogeneity: young households have low...

When structural labor supply models are unavailable or impractical, the paper proposes a practical method for incorporating behavioral responses into static taxbenefit microsimulation models. Using elasticity estimates from the literature, the proposed external evidence procedure offers a...

The tax and transfer system partially insures households against individual income risk. We build a framework to assess the size and (welfare) value of this partial insurance, which is based on exploiting distributional differences between household gross income and disposable income. Our...

Do factual immigration updates shift societal concerns across political ideologies? Conducting an online experiment in the lead-up to the 2024 U.S. Presidential Election, respondents provided local immigrant stock and flow estimates before being randomized to receive realistic information on...

This paper is the first to examine how adverse childhood experiences (ACEs) influence the support for income redistribution in adulthood. Using data from the 2022-2024 wave of the Global Flourishing Study on over 160,000 individuals from 22 countries, we construct measures of ACEs based on...

Chile combines high income levels and strong human development outcomes with persistent inequality. This paper examines the country's social protection matrix, focusing on its institutional configuration, financial structure, and main outcomes. The analysis distinguishes three core components-...

We study beliefs about wealth inequality and preferences for wealth redistribution, drawing on a large-scale online survey in Germany. Specifically, we assess participants' knowledge of the German wealth distribution, their perceived position within it, and the effects of two information...

Using a combination of individual-level, bioclimatic, ethnographic, and archaeological data, we investigate the ancient origins of cross-country variation in preferences for redistribution. Our hypothesis is that contemporary attitudes toward redistribution are shaped by ancestral inequality,...

We study how Americans trade off the welfare of the poor versus the rich using incentivized transfer experiments. Combining this with estimates of the Elasticity of Taxable Income, we quantify optimal income tax rates in the US. Revealed preferences show strong concern for the poor across the...

This paper examines how stable national disposable income inequality can coexist with substantial local reconfiguration in spatial inequality within a small, open, and highly integrated economy. Focusing on Luxembourg, where strong commuting flows and a nationally uniform tax-benefit system...

This paper argues that Colombia's taxation problems reflect a deeper political economy equilibrium shaped by extractive institutions, extreme inequality, and cultural norms that favor individual solutions over collective ones. Historical legacies produced a weak and often distrusted state, which...

This study examines how constitutionally embedded Islamic economic principles - declarations of an "Islamic Economy Provision," "Islamic Alms/Zakat Provision," and "Islamic Riba Provision" - affect income inequality in OIC (Organisation of Islamic Cooperation) countries over the period...

Objective ‒ The study's primary goal is to assess the relationship between income inequalities and attitudes toward them in various categories of localities in terms of population during 1988-2019. Research design & methods ‒ The study uses data on inequalities from the cyclical survey of...
