Special Issue Information

Dear Colleagues,

The literature on global inequality documents extreme wealth concentration, showing that the top of the global wealth distribution holds multiple times the wealth of the bottom half of humanity. It also demonstrates that growth-centric development models are failing to fulfil their promises of reducing poverty. In order to understand the links between growth, inequality, and poverty, we must examine several interconnected channels. These include how wealth and capital, rapid technological change, ongoing climate change challenges, the distributional consequences of financial shocks, labour market dynamics, and fiscal policy design jointly determine the evolving relationship between growth, inequality, and poverty. This Special Issue on “Income Inequality, Poverty and Economic Growth” invites researchers to submit theoretical or empirical papers that investigate the contribution of technological and climate changes, labour market dynamics, and financial and fiscal policies to the evolving relationship between growth, inequality, and poverty in the 21st century. The aim of this Special Issue is to bring together the latest research on why established growth and development models are failing to achieve their poverty and inequality reduction and sustainable growth targets.

This study examines how the composition of public education expenditure is associated with income inequality through educational quality and skill formation. While the existing literature largely focuses on aggregate education spending, this study argues that the allocation of resources across education levels plays a critical role in shaping educational outcomes and their distributional consequences. Using panel data for OECD countries over the period 2000–2022, we employ a simultaneous equation framework estimated using Three-Stage Least Squares (3SLS), complemented by a lag-structured empirical design and an instrumental-variable approach based on lagged expenditure to mitigate endogeneity concerns. The results reveal substantial heterogeneity across education levels. Tertiary education expenditure is positively associated with educational quality. Although its direct association with income inequality is not statistically significant, it exhibits a significant negative indirect association through the educational-quality channel. In contrast, spending at pre-primary, primary, and secondary levels exhibits weak or negative associations with measured learning outcomes and, in some cases, positive associations with income inequality. These patterns warrant cautious interpretation and may reflect diminishing marginal returns and endogenous policy responses in mature education systems. Further analysis suggests that educational quality serves as an important transmission mechanism linking education spending to income distribution, although no significant relationship is found with short-run economic growth, consistent with the long-term nature of human capital accumulation. Overall, the findings highlight the importance of improving the allocation and effectiveness of education spending rather than simply expanding aggregate budgets. Full article

The issues of income inequality and poverty are intrinsically linked and represent persistent global governance challenges. China faced significant hurdles, including absolute rural poverty and a widening urban–rural development gap. The “Targeted Poverty Alleviation” policy (TPA), implemented from 2014 onward, employed comprehensive measures, including household registration, industrial support, and skills training. By the end of 2020, this policy successfully eradicated absolute rural poverty under the prevailing standard, contributing a Chinese solution to global poverty reduction. Beyond addressing absolute deprivation, whether this policy has impacted relative rural poverty and urban–rural inequality remains a subject of debate in existing literature. Utilizing microdata from the China Family Panel Studies (CFPS) from 2014 to 2020, this study employs the Kakwani measure to measure relative deprivation levels, thereby identifying income disparities both within rural areas and between urban and rural regions. Combining empirical tools, including a Difference-in-Differences (DID) framework, Propensity Score Matching (PSM), and Entropy Balancing method, the analysis finds that the Targeted Poverty Alleviation policy significantly curbs income inequality both within rural areas and across the urban–rural divide. Further investigation reveals that this effect operates through three primary mechanisms: promoting diversified rural livelihoods, improving incomes for impoverished households, and bridging knowledge and information gaps. Heterogeneity analysis indicates that the inequality-reducing effect of the policy is more pronounced in non-major grain-producing regions, low-income provinces, and among vulnerable groups such as the elderly, low-income individuals, and women. This study addresses the lack of detailed micro-level measurement, deepens the explanatory analysis of mechanisms and heterogeneity, and provides a basis for formulating differentiated policies in line with the vision of common prosperity.

Inflation has become a major global economic issue, affecting household welfare and poverty reduction efforts, especially in developing countries. Despite growing scholarly attention, understanding of its conceptual foundations, emerging themes, and future research directions remains limited. This review analyzes international studies on inflation and household poverty from 2015 to 2025. Following PRISMA 2020 guidelines, 147 peer-reviewed English-language articles were selected from an initial pool of 659 records in the Scopus database and analyzed using the Biblioshiny package in R for performance metrics and science mapping. The findings reveal a rapidly growing and diverse research area, with an average annual growth rate of 20.77%, involving 362 authors across 147 journals. Most research focuses on high-income nations such as the United States, China, and the UK, while regions heavily affected by inflation-driven poverty, such as Sub-Saharan Africa and Central Asia, are less represented. Thematic analysis identifies five key areas: macroeconomic instability and inequality; household well-being and food security; energy poverty and commodity prices; COVID-19 and external economic threats; and multidimensional poverty combined with social policies. Around 30% of the publications feature international collaboration, reflecting increased global cooperation. Life-cycle analysis indicates the field is in a growth phase and may reach maturity around 2036. Overall, this review provides a detailed overview of the development and structure of research on inflation and household poverty, highlights notable geographic and thematic gaps, and offers valuable insights for future studies and policies aimed at reducing inflation’s adverse effects on vulnerable economies.
