It has been argued that when workers are already working long weeks, adding more hours can reduce productivity. This column tests this argument using evidence from Japan. The authors find that long working hours of key team members harm team productivity. In contrast, shorter hours cause the opposite effect, perhaps because workers recover from fatigue and arrive for work with increased energy and focus.

Employers in the US are grappling with whether and how to bring employees back to the office or other place of work. Using survey-based evidence, this column finds that four in ten Americans who currently work from home at least one day a week would seek another job if employers require a full return to business premises, and most workers would look favourably on a new job that offers the same pay with the option to work from home two or three days a week. High rates of quits and job openings in recent months appear to partly reflect a re-sorting of workers based on the scope for remote working.

While progress in closing gender gaps has been made, women around the world still earn less than men in the labour market. At the same time, income inequality across households has increased in recent decades. This column finds that the interaction of the marriage market and the labour market crucially impacts inequality across gender and within/between households. Policies that affect who marries whom (such as tax policies) or home production choices (such as parental leave or universal childcare) can mitigate or amplify inequality, calling for a better understanding of these spillovers across markets.

Do cultural norms determine whether women go back to work after having a child? And if culture changes, does their behaviour change too? Anna Raute and Uta Schӧnberg tell Tim Phillips how the reunification of Germany provided unique data.

Many continental European countries give workers a formal right to voice via board-level or shop-floor elected representation, but evidence on the effects of these arrangements is scarce. This column examines reforms in Finland that introduced or expanded workers’ rights to voice institutions. Overall, the reforms had non-existent or small positive effects on turnover, job quality, firm survival, productivity, and capital intensity. It may be that Finnish worker voice institutions operate through information sharing and cooperation, which do not substantially improve worker outcomes but also do not harm firm performance.

Despite a significant reduction in gender differences in the labour market over the last 40 years, they are still present in most advanced economies and do not appear likely to vanish soon. This column analyses the impact of culture, defined by women’s gender role attitudes, on maternal labour market decisions. It finds that social pressure is at least as strong as social learning in influencing labour market behaviour. Once these channels are accounted for, there is no direct effect of peers’ gender identity norms on labour force participation. Disseminating detailed statistics on female labour market outcomes and work attitudes may prove to be a cost-effective way to promote labour market participation, especially among less-educated mothers.

Worker representation on corporate boards has gained popularity as a way to promote the workers’ interests. This column explores whether worker wages are linked to worker representation on corporate boards, using ten years of data from Norway. Workers are paid more and face less earnings risk if they work in firms with worker representation on the board, but these benefits can be entirely explained by firm size and the share of unionised workers. While workers may benefit from being employed in firms with worker representation, they would not benefit from legislation mandating worker representation on corporate boards.

The extent to which negative monetary policy interest rates stimulate the economy has a subject of recent discussion among academics and policymakers. Using new comprehensive Danish microdata, this column shows that firms exposed to negative deposit rates to a higher degree than other firms increase their fixed investments and employment – after due control for changes in the level of interest rates. These findings are suggestive of an additional monetary transmission channel operating as nominal interest rates cross zero and become negative.

From the public discourse, it seems clear that we are living in an age of rising inequality. However, common measures of income and consumption inequality disguise a more nuanced pattern of inequality change across the world. This column argues that inequality within countries has not been rising everywhere and that inequality between countries has decreased. At the same time, technological progress is increasingly displacing basic labour in favour of skilled labour and capital, across borders, and widening the wage gap. The overall effect is unclear. National policies to mitigate inequality are needed but, in the absence of international cooperation, are constrained by cross-border spillovers.

Many countries are introducing mandatory wage transparency to address the seemingly intractable gender wage gap, but evidence of its effects on gender pay disparities and firm outcomes has, to date, been limited. To examine the benefits and costs of such policies, this column analyses the wages of firms prior to and following the introduction of Denmark’s 2006 Act on Gender Specific Pay Statistics. Mandatory transparency legislation reduced gender pay disparity, primarily by slowing down the growth of men's wages.

Artificial intelligence will transform job tasks and occupations. This column uses data from US online job postings during 2010–2019 to show how absolute and relative demand for AI-related skills has grown across all industry sectors and occupation groups. Jobs requiring AI skills command, on average, an 11% wage premium compared to similar jobs that do not require AI knowledge. However, AI is at least as much a managerial challenge as it is a technological challenge. Real productivity gains will come only when there are managers who can use AI to create and capture value.

Many countries, especially in Europe, are characterised by shared governance institutions that grant workers formal authority in firms’ decision-making. This column uses a natural experiment: a 1994 reform in Germany that abolished worker-elected directors in certain new firms and permanently preserved them in others, to provide empirical evidence on the effects of shared governance. It finds that shared governance can lead to an increase in capital formation and discusses the mechanisms which may lead to this result.

There is evidence that hot climatic temperatures and crime are linked. With climate change raising temperatures around the world, it is possible we may see higher levels of personal aggression. Based on data from Russia, this column shows that on hotter days, women are more likely to be killed in homicides, especially over weekends. Colder days have no similar effect on violence. Lower wages and higher unemployment contribute to higher homicide rates, so policies promoting employment may mitigate victimisation during extreme temperature days.

The US became the ‘arsenal of democracy’ by producing a massive amount of military goods that raised real GDP by 72% between 1940 and 1945. Yet, multiplier estimates for this expansion in government spending are less than one. Long-range studies at subnational levels show that military spending was associated with small effects on per capita activity. Military spending in the context of a quasi-command economy crowded out private consumption and investment and forced people into the military. In essence, Americans sacrificed heavily to win the war, while their Allies sacrificed even more.

Neutrality has long been viewed as impartiality in war. This column, part of the Vox debate on World War II, asserts that neutral states in the war were realist in approaching their defence to ensure their survival. Neutrals such as Portugal, Spain, Sweden, and Switzerland maintained independence by offering economic concessions to the belligerents to make up for their relative military weakness. Economic concessions took the form of merchandise trade, services, labour, and capital flows. Depending on their position and the changing fortunes of war, neutral countries could also extract concessions from the belligerents, if their situation permitted.

History has shown that new technology can disrupt societies, and current developments in automation have raised anxious speculation on what might happen if stable middle-class jobs are taken over by machines. This column analyses the impact of technological change on labour markets and social protests, taking the case of the adoption of electricity in early 20th century Sweden. It finds that electrification did increase the incidence of local strikes, but that disputes were associated with workers demanding higher wages and better working conditions rather than attempting to block innovation.

Changes in working hours and the associated time and energy consumed during work can exert an important influence on people’s fitness. However, the effects of such changes on health behaviour and obesity are not well understood. This column examines the effects of a 2001 French national reform that reduced working hours on employee obesity and overweight. Although reduced working times could, in theory, be used for health-promoting activities, in practice it had different effects on white- and blue-collar workers. Policies to reduce working hours alone do not necessarily produce better fitness for everyone.

Since the early 1980s, technology has reduced the demand for low and medium-skill workers, the young, and women, especially in manufacturing industries. The column investigates which technologies have had the largest effect, and on which types of worker. It finds that robots and software raised the demand for high-skill workers, older workers, and men, especially in service industries.

Multinational enterprises play an important role in coordinating production around the globe. This column presents a dynamic quantitative model of multinational enterprise expansion that can be used to analyse the effects of policies that affect the cost of the operations of such firms. It uses this model to estaimte the impact of potential implementations of Brexit.

The worldwide decline of the labour share is worrying, because the labour share is thought to be too low. This column attempts to derive an estimate of the socially optimal labour share. The calibration implies that the socially optimal share is 17% higher than the historical average.
