Finding employment in the formal sector in developing countries is difficult. Countries with an abundance of informal firms suffer from low aggregate productivity. This column suggests that as countries develop, more workers transition from the informal to the formal sector. A ten-year period of rapid growth in Vietnam displayed a decrease in the employment in the informal sector in favour of the formal one. Most of it was due to changing cohorts in the workforce. In addition, this transition leads to gains in aggregate productivity in the formalised sectors.

Italy’s productivity has been stagnant since the late 1990s. This column argues that public sector inefficiency could be partially responsible for the country’s low labour productivity. The evidence suggests that Italy could realise significant macroeconomic productivity gains if average public sector efficiency were to improve from its current faltering levels.

In recent decades, there has been an accelerated increase in top income inequality, particularly in developed countries. This column argues that innovation partly accounts for the surge in top income inequality and fosters social mobility. In particular, the positive effect of innovation on social mobility is due to new innovators.

Understanding the determinants of firm performance is important if we want to improve how we do business. This column presents new research on corporate efficiency in Europe, highlighting the importance of firm characteristics such as firm ownership. Evidence suggests that a mix of majority and minority shareholders drives efficiency.

International trade in services and immigration are among the fastest growing aspects of globalisation. Using UK data, this column explores the links between these phenomena. Immigrants promote exports of final services to their home countries, while also reducing imports for some intermediate services, and bringing productivity gains to the labour market. In designing immigration policies, it is important that the potential impact on exports and offshoring activities are carefully considered.

The shallow growth response to Eurozone rebalancing policies could point towards structural impediments. To uncover such impediments and design effective structural reforms, it is necessary to focus on the path from micro behaviour to macro outcomes. This column argues that firm-level data from the CompNet database can shed light on the impacts of structural reforms.

Manufacturing is often seen as the key to sustainable export and productivity growth in developing countries. This column argues that, while manufacturing played a key role in some countries’ development, high growth can be sustained without relying primarily on manufacturing. A process of learning, productivity improvement, and investment that touches all sectors characterises the most successful economies. Policies that artificially favour manufacturing should instead give way to maximising learning from the frontier in all sectors of the economy.

The US economy has strengthened considerably in recent years, presenting an opportunity to address the 40-year stagnation in incomes for the middle class. This column provides historical and international context for the key factors affecting middle-class incomes: productivity growth, labour force participation, and income inequality. It also outlines President Obama’s approach to economic policies – what he terms “middle-class economics” – which is designed to improve all three.

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.

It is often argued that for poor countries, increases in agricultural productivity result in higher non-agricultural output, but the theory is ambiguous and the empirical evidence is limited. This column presents evidence from a natural experiment provided by China’s early 1980s agricultural reforms. Higher agricultural output induced by the reforms led to quantitatively important growth in non-agricultural output. This growth appears to be primarily due to rural savings increasing the supply of capital to the non-agricultural sector.

It is generally agreed that firms can improve their employees’ wellbeing through improvements in job quality – but is it in their economic interests to do so? This column reports research showing that satisfied employees and higher productivity go together. Analysis of the British Workplace Employment Relations Survey finds that employee job satisfaction is positively associated with workplace financial performance, labour productivity, and the quality of output and service.

Minimum wage laws are often shown to have little impact on employment as the labour price rise can be offset by lower turnover, lower markups, and heightened efficiency, or ‘cleansing’ effects. This column shows that in a fast-growing economy like China, there is a ‘cleansing’ effect of labour market standards. Minimum wage growth allows more productive firms to replace the least productive ones and forces incumbent firms to become more competitive. Both mechanisms boost the aggregate efficiency of the economy.

Real wages continue to fall in the UK and elsewhere, yet despite this striking feature of the labour market, some commentators anticipate resurgent pay growth in the near future. This column argues that the absence of any improvement in the UK’s productivity performance – together with evidence that nominal wage growth is flatlining and real wage growth is falling – make it highly unlikely that wage growth is about to explode upwards.

Happy workers might well be more productive than unhappy ones, but high worker satisfaction could also be a sign that workers are overpaid or underworked. This column examines the link between worker satisfaction and future stock returns in 14 countries. In most but not all countries, employee satisfaction is associated with higher future stock returns. Abnormal returns to companies with high worker satisfaction are significantly increasing in the flexibility of their countries’ labour markets.

The Chinese government has been actively promoting innovation via policies such as R&D subsidies, tax relief, and location policies. Since 1995, central and local governments have established more than 100 clusters in over 60 cities. This column presents new evidence on the effect of the concentration of firms on product innovation (new products) in the manufacturing industries.

Innovation is a key driver of productivity growth, but innovation in the service sector has received relatively little attention. This column shows that the total factor productivity gap between Japanese firms with and without innovations is larger in services than in manufacturing. Whereas the percentage of firms holding patents is much higher in manufacturing than in services, trade secrets are just as important in both sectors. These results suggest that the protection of trade secrets makes an important contribution to productivity growth.

The rise of trade in intermediate inputs is well documented, but its role in shaping domestic economies is not yet completely understood. This column presents evidence from French firms on the effects of importing intermediate inputs. Firms importing more varieties of intermediate inputs increased their productivity and exported more varieties. Foreign inputs from the most advanced economies have the strongest effect on firm productivity, but imported inputs from all countries help raise the number of export varieties.

Brazil has grown rapidly and reduced poverty over the past decade, but it has grown more slowly than other emerging economies and its income per capita remains relatively low by global standards. This column points out that sectors of the Brazilian economy that have been opened up to international competition have outperformed those that remain heavily protected. Deeper integration into global markets and value chains could provide competitive pressures that would improve Brazil’s productivity and living standards.

Trade liberalisations are often accompanied by labour market reforms, making it difficult to isolate their effects. This column discusses the effects of trade liberalisation, globalisation, and labour-market reforms on the Colombian labour market. Reduced trade frictions increased cross-firm wage inequality and shifted the firm-size distribution rightward, with offsetting effects on overall wage inequality. Average income increased, but the gains were concentrated among employees of large, productive firms with access to export markets. Greater trade openness also increased job turnover.

Headquarters play important strategic roles in modern companies, but downsizing of headquarters is often advocated as a cost-cutting measure. This column presents evidence from Japanese firm-level data that the size of headquarters is positively associated with firms’ overall productivity. Moreover, the benefits of ICT are greater for companies with relatively large headquarters. Downsizing headquarters to cut costs may thus be harmful for long-term company performance.
