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.

Europe is experiencing a wave of mergers in the telecommunications industry. This column argues that an increase in market concentration in the mobile industry generates an important potential trade-off: while consolidation increases prices, investment per operator also goes up. Competition and regulatory authorities should be open to the potential trade-off between market power effects and efficiency gains from agreements between firms.

There is a cross-country relationship between economic performance and both economic and political diversification. This column presents global evidence that between 1962 and 2012, both types of diversification were closely related to economic performance. This period included the spread of democracy, the global liberalisation of trade, and the termination of the Cold War. The recent retreat of democracy, the popular reaction to trade liberalisation in key countries, and a new cold war appear likely to reduce economic efficiency and growth.
