Studies have confirmed an increase in earnings inequality in Japan, but do not agree on how or when it increased, or which groups were most affected. This column decomposes changes in earnings data to show a recent decrease in the returns to general human capital of almost all Japanese workers, at the same time as an increase in the returns to firm-specific human capital among male workers with high wage rates. Gender-based wage inequality has persisted.

Diversified business groups and conglomerates have been shown to withstand economic shocks better than equivalent standalone companies. This column uses employment data from France to argue that business groups use internal labour markets to save on termination, search, and training costs, which helps them cope with unexpected changes. These internal markets also provide implicit employment insurance to employees.

Amid a persistent fall in oil prices, many oil-exporting countries are realising that economic diversification should be a top priority. One important pathway is to create a dynamic export sector. This column argues the standard policy of structural reforms – which mostly tackle ‘government failures’ rather than ‘market failures’ – are not sufficient. The state needs to intervene to change the incentive structure of firms and workers, and impose a strict accountability framework.

Health and education are two key components of human capital. In this video, Adrienne Lucas discusses the impact of the treatment for HIV+ parents on their children’s school achievements. This video was recorded during a UNU-WIDER conference on “Human capital and growth” held in June 2016.

In this video, Kehinde Ajayi discusses the ways in which schools affect students’ performance. Allowing students to make informed choices about which school to attend is key to improving educational attainment. This video was recorded during a UNU-WIDER conference on “Human capital and growth” held in June 2016.

Education usually has a protective effect – people with higher levels of education are less likely to start criminal activities. In this video, Giovanni Mastrobuoni discusses the benefits of education on members of the Italian-American Mafia. Although the nature of the business is illegal, those involved in business-related crimes (loan sharking, drug dealing) are those who gain the most from an extra year in school. This video was recorded in March 2016 during the Royal Economic Society’s Annual Conference held at the University of Sussex.

A city’s metropolitan governance structure has a critical influence on the quality of life and economic outcomes of its inhabitants. This column quantifies the impact of governance on productivity using data from five OECD countries. Administrative fragmentation, which complicates policy coordination across a city, has a negative effect on individual productivity. This finding, combined with benefits from good governance such as improved transport and lower pollution levels, highlights the importance of well-designed metropolitan authorities.

Italy’s economic performance is lagging behind other Eurozone and OECD countries. This column argues that radical changes in human capital, financial, innovation and product markets, and taxation would restore growth, but will take time to bear fruits. This leaves no room for complacency in the ongoing reform efforts.

Vocational training programmes offer a second chance to those who drop out of the formal education system. Most studies of the success of such programmes, however, typically only analyse outcomes directly after participation. This column examines the medium- and long-term outcomes of a vocational training programme in Colombia. Results suggest that vocational training and formal education are complementary investments and that there are educational spillover effects for family members, in particular among applicants with high baseline educational attainment.

Workers who switch firms can lose firm-specific human capital. This column presents evidence of how moving to occupationally specialised firms can compensate workers for wage losses that are caused by ‘specific human capital’. When switches occur between firms that are very distant from each other in terms of their knowledge structure, occupationally specialised firms are prepared to pay a wage premium that can outweigh the costs of such long-distance switches.

The relationship between aggregate output and income inequality is central in macroeconomics. This column argues that greater income inequality raises the economic growth of poor countries and decreases the growth of high- and middle-income countries. Human capital accumulation is an important channel through which income inequality affects growth.

Policymakers have used a variety of measures to promote firm innovation but their exact impact remains unclear. This column argues that regional context, proxied by investment in R&D and education levels, is fundamental in shaping the innovative performance of firms. The local socioeconomic environment either favours or limits the innovative capacity of firms, depending on their level of interaction both with neighbouring and distant economic actors.

The rapid growth of the US financial sector has driven policy debate on whether it is socially desirable. This column examines the trade-off between finance and entrepreneurship, and links the growth of finance to rising wealth inequality. Although financial intermediation helps allocate capital efficiently, people choosing a career in finance do not internalise the negative effect on the pool of talented entrepreneurs. This mechanism can explain the simultaneous growth of wealth inequality and finance in the US, and why more unequal countries have larger financial sectors.

The negative consequences of dual labour markets have been extensively documented, but so far little attention has been paid to their effects on workers’ on-the-job training and cognitive skills. This column discusses evidence from PIAAC – an exam for adults designed by the OECD in 2013. Temporary contracts are associated with a reduction of 8–16 percentage points in the probability of receiving on-the-job training, and this training gap can explain up to half of the gap in numeracy scores between permanent and temporary workers.

Admission to higher education often depends on the results of high-stakes tests, but assessing the consequences of having a ‘bad day’ on such tests is challenging. This column provides evidence from a dataset on Israeli high-school students. Random variations in pollution have measurable effects on exam performance, and these in turn have significant effects on students’ future educational and labour-market outcomes. The authors argue that placing too much weight on high-stakes exams may not be consistent with meritocratic principles.

Like any insurance mechanism, unemployment benefits involve a trade-off between risk sharing and moral hazard. Whereas previous studies have concluded that unemployment insurance is close to optimal in the US, this column argues that replacement rates should vary over the life cycle. Young people typically have little means to smooth consumption during a spell of unemployment, while the moral hazard problems are minor – regardless of replacement rates, the young want jobs to improve their lifetime career prospects and to build up human capital.

Africa has generated a lot of enthusiasm lately. The cynical view of the continent as a hopeless basket case has been replaced by the lofty narrative of Africa Rising. This column argues that Africa’s progress is impressive, and there is more to the story than a commodity boom. But Africa is at a crossroads. The opportunities are huge, but the road ahead is long, and will require persistent and patient effort from policymakers as well as business.

Grade inflation is widely viewed as detrimental, compromising the quality of education and reducing the information content of student transcripts for employers. This column argues that there may be benefits to allowing grade inflation when universities’ investment decisions are taken into account. With grade inflation, student transcripts convey less information, so employers rely less on transcripts and more on universities’ reputations. This incentivises universities to make costly investments to improve the quality of their education and the average ability of their graduates.

Although studies of contemporary economies find robust associations between human capital and growth, past research has found no link between worker skills and the onset of industrialisation. This column resolves the puzzle by focusing on the upper tail of the skill distribution, which is strongly associated with industrial development in 18th-century France.

Most developing countries have made a great effort to eradicate illiteracy. As a result, the inequality in the distribution of education has been reduced by more than half from 1950 to 2010. However, inequality in the distribution of income has hardly changed. This column presents evidence from a new dataset on human capital inequality. The authors find that increasing returns to education, globalisation, and skill-biased technological change can explain why the fall in human capital inequality has not been sufficient to reduce income inequality.
