Labour shares, inequality, and the relative price of capital
Loukas Karabarbounis, Brent Neiman 25 November 2014
The share of compensation to labour in gross value added has declined in recent decades for most countries and industries around the world. Recent work has also used the share of compensation to labour in net value added as a proxy for inequality. This column discusses that gross and net labour shares have declined together for most countries since 1975 – an outcome consistent with the worldwide decline in the relative price of investment goods.
At least since Kaldor (1961), the constancy of the labour share of income has been considered one of the key foundations underlying macroeconomic models. In Karabarbounis and Neiman (2014a), we documented a global decline in the share of labour compensation in gross income (‘gross labour share’) since 1975 and emphasised the role of declining investment prices for this trend. Piketty (2014) and Piketty and Zucman (2014) also discussed this factor share movement and linked it to increases in the capital–output ratio.

Job polarisation and the decline of middle-class workers’ wages
Michael Boehm 08 February 2014
Employment in traditional middle-class jobs has fallen sharply over the last few decades. At the same time, middle-class wages have been stagnant. This column reviews recent research on job polarisation and presents a new study that explicitly links job polarisation with the changes in workers' wages. Job polarisation has a substantial negative effect on middle-skill workers.
The decline of the middle class has come to the forefront of debate in the US and Europe in recent years. This decline has two important components in the labour market. First, the number of well-paid middle-skill jobs in manufacturing and clerical occupations has decreased substantially since the mid-1980s. Second, the relative earnings for workers around the median of the wage distribution dropped over the same period, leaving them with hardly any real wage gains in nearly 30 years.

The long-run gains of not mixing genders in high-school classes
Massimo Anelli, Giovanni Peri 23 February 2013
What causes fewer women than men to choose high-earning potential subjects such as engineering, economics or science at undergraduate level? This column presents new evidence from an accidental natural experiment in Italy, suggesting mixed-gender classes at the high-school level reduce the number of women pursuing these subjects. These results suggest that gender-separated classrooms are an effective way to increase women’s career opportunities and salaries.

Jobs: The next piece of Africa’s growth jigsaw
David Fine, Susan Lund 04 December 2012
Africa's recent growth is impressive, yet its rate of stable job creation is anything but. This column argues that Africa needs rapid growth in stable, wage-paying jobs in order to ensure future stable growth and prosperity. African governments must develop and implement targeted jobs strategies – which focus on labour-intensive, competitive industries – to get the most out Africa’s rapid economic emergence.
Africa’s recent economic performance has been impressive. With average annual growth of 5.1% over the past ten years, the continent is the second fastest-growing region in the world (IMF 2012). The share of people in extreme poverty is falling. Since 2000, 31 million African households have joined a 90 million-strong consuming class with discretionary income to spend or save1.

Jobless recoveries and the disappearance of routine occupations
Henry Siu, Nir Jaimovich 06 November 2012
The US economy is recovering. But what explains the stubborn malaise in its labour market? This column argues that future recovery from recession will likely be jobless because technological advances and mechanisation now enable troubled firms to shed middle-income jobs in favour of machines and automation. If these jobs are not recouped during subsequent economic recovery, future recoveries may well remain jobless.
Economic recoveries aren’t what they used to be. Since the end of the Great Recession in June 2009:
