Studies often find an aggregated near-zero employment effect when increasing the minimum wage. But the effects might vary if local employers in different regions have different market power. The column examines increases in the minimum wage in Japan and finds a more pronounced negative employment effect in local labour markets where employers had less control over wages.

Concentrated labour markets, in which workers have few choices of potential employers, reduce the wages of workers when they are not covered by collective wage bargaining agreements. But these types of agreements have become much less common in the past 20 years. This column uses employee-level data to show that even though UK labour markets have not on average become much more concentrated, concentration – which varies a great deal across regions and industries – is having a bigger impact on wages than before.

The effect of increasing product market concentration on the labour market is sometimes overlooked because the labour market is often assumed to be entirely competitive. This column discusses the definition of labour markets and analyses the circumstances in which employers have monopsonist power to set wages, thus contributing to the growing debate over whether market concentration might be one cause of stagnant wages and other labour trends.

Monopsony refers to the market power that employers wield in labour markets. This column explores monopsony power in online labour markets, using observational and experimental data from Amazon’s Mechanical Turk platform. Both datasets suggest an employer labour supply elasticity of close to 0.1, suggesting that a 10% reduction in wages would only see a 1% drop in willing labour. This points to substantial employer market power in a supposedly frictionless setting.
