Power law distributions are ubiquitous in socioeconomic contexts. While their general properties are well understood, it is often less clear why they regularly appear in empirical data. What are the generative mechanisms leading to power laws, how do they arise in the real world? This paper aims...

In this report, we consider policies to help people appropriately manage their defined contribution (DC) pension wealth through later life. We draw on evidence in a report published alongside this one (Boileau, Cribb and Emmerson, 2025), which sets out key information on the landscape in which...

This report is one of two reports on the management of pension wealth in retirement conducted as part of the Pensions Review, led by the Institute for Fiscal Studies in partnership with the abrdn Financial Fairness Trust. In this report, we examine the decisions that older individuals face as...

Accurate and comprehensive measurement of household livelihoods is critical for monitoring progress toward poverty alleviation and targeting social assistance programs for those who most need it. However, the high cost of traditional data collection has historically made comprehensive...

This study investigates the key drivers behind the wealth accumulation of America's 100 richest self-made billionaires, using data from the Forbes 400 list. Focusing on five individual and contextual factors - education, innovation, networks, inheritance, and geographic origins - the research...

Two mechanisms have been proposed to explain sex selection in India: son preference in which parents desire a male heir and daughter aversion in which dowry payments make parents worse off with girls. Our model incorporates both mechanisms, providing micro-foundations, based on the organization...

Wealth is increasingly unequally distributed in many countries. This study examines public perceptions of wealth deservingness and preferences for taxing the wealth of the rich, focusing on how opinions vary based on the amount, use, and origin of wealth. Drawing on an original vignette...

We study the effects of envy (relative consumption concerns), drawing on evidence that preferences typically exhibit present bias. We employ a Ramseytype model with agents who differ in initial capital endowments and account for present-biased envy: agents are naive and care about how their...

In the absence of a wealth register, Belgian wealth inequality needs to be estimated. Here I apply the mortality multiplier approach to Belgian inheritance tax tabulations and administrative microdata, collectively covering 1935 to 2022. Belgian wealth inequality has strongly declined during the...

We embed an experiment in a large-scale representative survey to investigate how relative wealth affects risk-taking and how this effect varies as a function of perceived control over life outcomes. Our results contest the common prediction of higher risk-taking in the middle of the...

How much is owed today to Blacks and other groups who have suffered substantial past economic violence? The issue has become extremely relevant given the $105 million reparations program announced by the City of Tulsa on June 1, 2025. To make some progress on this complex issue, this short paper...

Flat tax systems have gained traction in countries that transitioned from socialism, with more than 20 nations in Eastern Europe and Central Asia adopting such systems since the mid-1990s. These reforms aimed to streamline tax processes, enhance compliance, and boost economic growth. While...

I evaluate the link between automation and the rise in top income concentration when inequality matters for macro. The novel mechanism is that automation redistributes income towards high-wealth households who save more, which lowers the interest rate and incites firms to automate more. To...

Estimates of social insurance pension wealth are available for a number of Western economies, including Austria for the year 2017. Such wealth may be compared with conventional wealth in terms of size and distribution and when we add such estimates to measures of wealth in the conventional...

Wealth is increasingly unequally distributed in many countries. This study examines public perceptions of wealth deservingness and preferences for taxing the wealth of the rich, focusing on how opinions vary based on the amount, use, and origin of wealth. Drawing on an original vignette...

Women are more dependent on intra- and inter-generational transfers for wealth accumulation than men (Bartels et al. 2023, Black et al. 2022), yet the role of inheritance in closing gender wealth gaps remains poorly understood. Using Swedish registry inheritance data between 2002-2004 and panel...

The total wealth of Britain's households in 2018 to 2020 was approximately £2.2 trillion less than was previously believed - a 14% reduction. That, at least, is the implication of a recent change in methodology made by the Office for National Statistics (ONS) to the UK's leading official...

The current system of private pension savings in the UK is based on employers choosing a workplace pension provider, to which contributions from the employee and employer are sent, and which invests the contributions on behalf of the employee. This means that when an individual leaves their...

This report examines ethnic differences in pension participation in the UK following the nationwide roll-out of automatic enrolment, the drivers of those gaps, and the consequences for wealth accumulation. It draws on an academic research paper (Cribb, O'Brien and Sturrock, 2025) published...

This report describes patterns of co-residence of young adults at a parental home in the United Kingdom. We show how the rate of co-residence varies across dimensions such as income, region and ethnicity. We show how it has changed in recent years and discuss potential drivers of the rise...

How does economic growth affect individual wealth accumulation and, thereby, wealth inequality? Combining individual wealth from the Socio-Economic Panel (SOEP) and local GDP growth across 401 German counties, this paper documents a sizable Hometown-Growth-Wealth Nexus. We find that past...

The growing demand for sustainable business practices has led to the development of corporate sustainability assessment tools, with environmental, social, and governance (ESG) indicators becoming central to non-financial performance evaluation. These metrics increasingly influence investment...

This paper estimates rates of return on wealth across gross wealth groups by matching individual-level survey data with macroeconomic return data for Germany. Using machine learning for more detailed financial asset categories, we find that the average nominal rate of return on gross assets for...

This paper investigates the long-run nexus between wealth inequality and aggregate output using a DSGE model in which wealth inequality endogenously affects individual entrepreneurship incentives, thereby influencing aggregate output. Our model passes the indirect inference test against the UK...
