Increased globalisation since the mid-1990s has eroded some of the tax bases of many economies. At the same time, demand for public goods has risen and governments face the challenge of financing greater public expenditure with lower tax revenues. This column discusses tax policy responses to increasing globalisation, showing that since the mid-1990s governments in OECD countries have increasingly relied on revenues from employee-borne rather than firm-borne taxes. Due to the greater mobility of capital and high-skilled workers, who are able to escape higher taxes more easily, the middle classes have carried much of the additional tax burden.

The effect of an individual’s place of residence on their life chances has long been discussed in public policy debates. This column uses British Household Panel Survey data to assess whether birthplace plays a role in determining future earnings. On average, an individual born in London in the 1970s will earn around 7% more than an individual of the same age and gender born in Manchester; who in turn will earn 5.5% more than an individual born in Cardiff. Parental sorting and the influence of birthplace in decisions about current location both play a role in explaining this effect.

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.

Some economists argue that income inequality suggests intra-generational mobility in society. This column provides comprehensive evidence across a large number of advanced economies on the importance of intra-generational mobility and its relationship with earnings inequality. The findings do not support the belief that higher earnings inequality necessarily goes hand-in-hand with greater mobility over the working life. Higher inequalities are not systematically compensated by higher mobility opportunities.

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.

Taxation in developing nations has always been difficult, but the Global Crisis has brought further complications. This column examines and compares the tax revenue trends in Asia and Latin America to shed light on some of these issues. Despite their similarities, there is no one-size-fits-all explanation for tax/GDP ratios between the two regions. While progress has been made, the gap between the advanced economies and developing countries offers ample room for improvement. This is particularly important for developing nations as they face growing demand for fiscal spending.

With the new UN Global Goals agreed this autumn, the issue of poverty is at the top of global agenda. This column presents a new book that reviews past and present debates on poverty in both rich and poor countries. The challenges ahead are in assuring the political will and administrative capabilities to implement and enforce sound anti-poverty policies, and in adapting them to differing circumstances and evolving knowledge about their efficacy.

The gender gap in the workplace persists, affecting women in professional and managerial occupations the most. This column looks at the gender gap among top executives at Standard & Poor’s firms and suggests that performance-related pay schemes should be better scrutinised. Increasing transparency of an executive’s compensation relative to others in similar positions might go some way towards mitigating gender pay inequality for top executives.

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.

The COP21 conference faces a severe problem when it comes to funding climate adaptation in developing countries. This column examines novel strategies to increase the funding. The strategies are based on high individual carbon emitters wherever they are in the world, rather than according to the responsibilities of high-emitting countries. To this end, a global distribution of individual income and CO2e emissions is constructed.

Thomas Piketty and others have prompted renewed interest in understanding long-term patterns of inequality. This column presents evidence from pre-industrial Europe. Inequality rose even during the success stories of early modern Europe, but it can hardly have been the sole requisite for growth. In both economic history and today’s economic theory, the idea of a universal trade-off between growth and inequality needs to be replaced by stronger attention to social processes and institutional developments.

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.

Early childhood education has important effects on the academic readiness and ultimate life chances of children. This column examines how the introduction of the educational television show Sesame Street in the US affected primary school outcomes for disadvantaged children. Those from counties that had better access to the broadcast had superior educational outcomes through their early school years. These effects were particularly pronounced for black, non-Hispanic children, and those living in economically disadvantaged areas. The extremely low cost per child of such interventions make them ideal for addressing educational inequality in childhood.

China’s cities suffer from extremely high levels of air pollution, and Chinese consumers spend more than $US100 million on anti-smog products per year. Using recent internet sales data, this column explores how investing in such self-protection products varies for consumers with different income brackets. The urban poor are shown to be less likely to engage in this health-improving strategy. This suggests that cross-sectional income comparisons understate lifetime inequality.

Our level of income is unarguably dependent on where we live in the world. But evidencing this is tricky. This column presents a model that explains global income variability using one variable only – where you live. The results suggest that we might want to reassess how we think about both economic migration and global inequality of opportunity.

History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also uncover a new fact: in both international and cross-state U.S. data, there is a significant and robust negative relationship between religiosity and patents per capita. Three long-term outcomes emerge. First, a "Secularization" or "Western-European" regime with declining religiosity, unimpeded science, a passive Church and high levels of taxes and transfers. Second, a "Theocratic" regime with knowledge stagnation, extreme religiosity with no modernization effort, and high public spending on religious public goods. In-between is a third, "American" regime that generally (not always) combines scientific progress and stable religiosity within a range where religious institutions engage in doctrinal adaptation.

International trade has significant effects on domestic labour demand. It opens up new markets for export, but also creates opportunities for off-shoring. This column presents the results of a study on trade, wages and collective bargaining using data on French manufacturing firms. Both exporting and offshoring are found to have positive effects on wages, with collective bargaining agreements, particularly those at the firm-level, seeing greater wage gains for all types of worker.

Racial disparities in socioeconomic conditions remain a major policy issue throughout the world. This column applies a new neighbour-based measure of residential segregation to US census data from 1880 and 1940. The authors find that existing measures understate the extent of segregation, and that segregation increased in rural as well as urban areas. The dramatic decline in opposite-race neighbours during the 20th century may help to explain the persistence of racial inequality in the US.

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.

Jason Furman, 20 February 2015

The US economy has strengthened considerably in recent years, presenting an opportunity to address the 40-year stagnation in incomes for the middle class. This column provides historical and international context for the key factors affecting middle-class incomes: productivity growth, labour force participation, and income inequality. It also outlines President Obama’s approach to economic policies – what he terms “middle-class economics” – which is designed to improve all three.
