Between 1978 and 2015, China moved being from a poor, underdeveloped country to the world’s leading emerging economy. But relatively little is known about how the distribution of income and wealth within the country changed over this period. This column presents the first systematic estimates of the level and structure of China’s national wealth since the beginning of the market reform process. The national wealth-income ratio increased from 350% in 1978 to 700% in 2015, driven mainly by the increase of private wealth.

Recent research into the share of wealth owned by the richest households has given us important insights into trends in inequality. This column shows how we can now estimate the share of wealth owned by the richest households in Europe, and how many they numbered, from 1300 to the present day. Throughout this time, the only significant declines in inequality were the result of the Black Death and the World Wars.

Anthony B. Atkinson passed away on the morning of 1 January 2017 at the age of 72, after a long illness. This column describes how he established a unique place for himself among economists over the past half-decade by putting the question of inequality at the centre of his work while demonstrating that economics is first and foremost a social and moral science, in defiance of prevailing trends.

Recent studies on intergenerational income mobility have looked beyond the two-generational model to the role of grandparents, but multigenerational patterns in the wealth distribution have received less attention. This column uses a Swedish four-generational wealth dataset to study the role of family background for people’s wealth status and how much of this that is due to material inheritance. Most of the transmission in wealth status between generations comes from parents in the form of bequests and gifts, with only a marginal contribution from grandparents.

Household micro-data reveal striking differences in secured debt holdings across Eurozone countries. This column presents new evidence on the role of household characteristics and country institutions in accounting for the cross-country patterns observed. In countries with lengthier asset repossession periods, young or low-income households face higher borrowing costs, leading to a lower probability of holding mortgages.

Economists normally study wealth formation and inequality among the adult population, but some people already possess economic resources in early childhood. This column uses data from Denmark to examine childhood wealth and the role of wealth transfers early in life. A main result is that wealth inequality starts as early as childhood. Although overall wealth levels in childhood are low, they are better predictors of wealth in adulthood than parental wealth.

The ratio of wealth to income has increased substantially since WWII. Despite the key role of housing wealth in this process, an appropriate macroeconomic model that can explain recent history and assess the future is still lacking. This column presents a novel macroeconomic model designed to investigate the evolution of housing wealth in a growing economy with a fixed overall land supply. A key implication is that rising house and land prices are natural phenomena in a growing economy. Further, rising wealth-to-income ratios appear to be an important trigger for the long-term growth of the finance industry.

Recent decades have seen a remarkable increase in the concentration of wealth in the hands of the wealthiest in the US. This column examines which factors may have driven this increase. The evidence points to higher wage inequality, often attributed to new developments in the technology of production, as the main driving force, followed by tax cuts for top earners and more generous public transfers as secondary factors.

Jason Furman, 17 March 2016

The US is becoming ever more unequal. This column assesses the 2016 Economic Report of the President, highlighting that middle-class incomes are shaped by productivity growth, labour force participation, and the equality of outcomes. As the US economy moves beyond recovery from the Global Crisis, its policy stance should focus on promoting each of those factors to foster inclusive growth.

The World Bank has identified 37 countries as being in a ‘middle-income trap’, but few formal tests of the middle-income trap hypothesis exist. This column presents a new test based on a more nuanced observation that incorporates information on a country’s long-run growth path. Only seven out of 46 middle-income countries are found to be potentially ‘trapped’. Some countries that are usually considered to be trapped may just be growing very slowly.

Thomas Piketty’s "Capital in the Twenty-First Century" quantified the evolution of wealth inequality and concentration over time and across a number of countries. This column examines existing macroeconomic models of wealth inequality through the lenses of the facts and ideas in Piketty’s book. It further examines the importance of the mechanism that Piketty champions – post-tax rate of return on capital. Gaps in existing knowledge and directions for future research are identified. 

Daniel Waldenström, 20 December 2015

Recent work on the importance of wealth and capital shows that it has fluctuated grossly over time in Europe. This column examines whether this pattern carries over to smaller, late-industrialising countries by looking at new historical evidence from Sweden. After being low in the pre-industrial era, Swedish wealth levels came into line with the rest of Europe in the 20th century. However, government wealth grew much faster and became more important in Sweden, largely due its public pension system. These findings highlight the role of economic and political institutions in the long-run evolution of national wealth.

The concentration of personal wealth has received a lot of attention since the publication of Thomas Piketty’s Capital in the 21st Century. This column investigates the UK and finds wealth distribution to be highly concentrated. The data seem to suggest that the top wealth share has increased in the UK over the first decade of this century. 

Facundo Alvaredo, Tony Atkinson, Salvatore Morelli, 06 September 2015

The concentration of personal wealth is now receiving a great deal of attention – after having been neglected for many years. One reason is the growing recognition that, in seeking explanations for rising income inequality, we need to look not only at wages and earned income but also at income from capital, particularly at the top of the distribution. In this paper, we use evidence from existing data sources to attempt to answer three questions: (i) what is the share of total personal wealth that is owned by the top 1 per cent, or the top 0.1 per cent? (ii) is wealth much more unequally distributed than income? (iii) is the concentration of wealth at the top increasing over time? The main conclusion of the paper is that the evidence about the UK concentration of wealth post-2000 is seriously incomplete and significant investment is necessary if we are to provide satisfactory answers to the three questions.

Piketty's justification for his proposed wealth tax relies on the notion that the rate of return on capital exceeds economic growth. This column challenges this basis, arguing that it fails to account for risk. The authors also examine the relative merits of a consumption tax, which may be more valid.

The extent to which lifetime incomes are determined by inherited wealth is a politically sensitive issue, but long-run evidence on this question is limited. This column presents evidence on Swedish inheritance flows since the early 19th century. Despite a long history of aristocracy, accumulated capital was small relative to income in pre-industrial Sweden. In more recent times, Sweden stands out as a country where the return of capital has not automatically translated into a return of inherited wealth.

Per Krusell, Tony Smith, 01 June 2014

Thomas Piketty’s new book has been widely praised for its empirical contribution, but his prediction of rising inequality rests on economic theory. This column argues that Piketty’s pessimistic forecast is based on an extreme – and unrealistic – assumption about households’ saving behaviour. According to standard theory, the wealth–income ratio would increase only modestly as growth falls, so declining growth would not be a powerful force for generating high inequality.

Tony Atkinson, Salvatore Morelli, 26 March 2014

Inequality – long ignored – is now centre stage in debate about economic policy around the globe. This column introduces the Chartbook of Economic Inequality, a summary of long-run changes in economic inequality for 25 countries over more than 100 years.

Angus Deaton, 20 March 2014

The world has become healthier and wealthier since 1960, as measured by life expectancy and GDP per capita. In this column Angus Deaton introduces his new book and argues that the world is indeed a better place than it used to be, albeit with big setbacks, and that progress opens up vast inequalities.

Fiscal consolidation, and public concern that its pain be fairly spread, is putting tax systems under considerable pressure. This column takes stock of how they have been faring, and how they could do better.
