Political Wealth and Economic Inequality: Evidence from Declared Assets of Indian MPs, 2004–2024

Purpose: This study investigates the growth and concentration of political wealth in India. By researching the declared assets of Members of Parliament (MPs) for five Lok Sabha election cycles spanning the years 2004 to 2024. Design/methodology/approach: Mandatory affidavits submitted to the Election Commission of India (ECI) and processed by the Association for Democratic Reforms (ADR),  are used for the source of data.      Inequality within the political class is assessed using Gini coefficients, top decile wealth shares, and Pareto tail indices. Findings: We record a sharp increase in median and mean MP wealth, a thickening upper tail, and an increasing distance between political elites and the masses Our results show intensifying concentration of MP wealth over time. Real (inflation adjusted) asset values reveal substantial appreciation beyond nominal price movements, consistent with the “winner’s premium” documented in the political economy literature. Regional analysis shows sharp divergence: MPs in governance challenged BIMARU states exhibit returns to office far exceeding regional economic growth, while MPs in dynamic southern states mirror private sector capital accumulation. Comparing MP wealth growth with regional per capita income demonstrates persistent and universal excess, widening the representative–represented gap. The findings suggest that India’s “Billionaire Raj” is not merely an economic phenomenon but is deeply embedded within its legislative institutions. Research limitations/implications: The affidavit data may under-report the wealth as candidates tend to declare their real estate at circle rates, do not report benami holdings and differ in accuracy of reporting. Regional PCI figures are unweighted averages of state incomes, which underweights populous poorer states; this is likely to understate the divergence between MP wealth and regional economic conditions.  Such limitations also highlight the need for future work that would incorporate affidavit verification, circle-rate adjustments, or triangulation with tax data where possible, to recover a more accurate picture of political wealth. Additionally, it highlights the necessity of population-weighted measures of regional inequality and implies that the accumulation of political wealth might be less correlated with constituent welfare than current estimates imply. Originality/value: Existing studies document returns to winning office but do not study how political wealth is distributed, how inequality evolves over time, how regional political wealth diverges from regional economic conditions, or how the statistical structure of political wealth has changed. This study addresses these gaps by providing the first multi-cycle distributional analysis of MP wealth (2004-2024), the first inflation-adjusted assessment of real political wealth growth, the first regional comparison of MP wealth against regional income, and the first formal modelling of the lognormal-Pareto structure of political wealth.
