Oil and Natural Gas Prices and CPI Inflation in G20 Economies: A Cross-Country Empirical Analysis, 2018–2024

This paper utilizes bivariate OLS regressions and correlation analysis on monthly data from 2018 to 2024 to systematically map the varying degrees of co-movement between crude oil, natural gas prices, and CPI inflation across eighteen G20 economies, finding that oil is a significant driver in most nations while natural gas impacts are concentrated in specific markets like Italy, Mexico, Argentina, and Turkey, thereby establishing a descriptive baseline for future causal research.

A Novel Subgroup Decomposition of Income Inequality: Resolving the Information Mixture Problem

This paper proposes a novel subgroup decomposition methodology based on the Unequally Distributed (UD) and Relative UD (RUD) income framework to resolve the "information mixture problem" in conventional approaches by isolating a foundational egalitarian baseline, thereby enabling a mathematically consistent partitioning of income inequality into pure within-group and between-group components.

Non-cognitive Abilities and Urban-Rural Income Inequality: A Transdisciplinary Analysis of Heterogeneous Returns in China

Using 2018 China Family Panel Studies data, this paper demonstrates that non-cognitive abilities generate significantly larger income returns for rural residents—particularly low-income earners—than for urban counterparts, suggesting that cultivating these traits offers a promising, overlooked strategy for reducing China's urban-rural income inequality.
