The impact of the Global Crisis of 2008 played out differently in middle-income countries compared to developed countries. This column argues that the associations of growth level, growth volatility, shocks, institutions, and macroeconomic fundamentals have changed in important ways after the crisis. Educational attainment, share of manufacturing output in GDP, and exchange rate stability appear to increase the level of economic growth. Exchange rate flexibility, education attainment, and lack of political polarisation reduce the volatility of economic growth.

Most analysis of long-run economic performance abstracts from short-run fluctuations and seeks to explain improved performance through an increase in the rate of growth. Using data on annual rates of change of per capita income reaching back to the 13th century for some countries, this column show that improved long-run performance has actually occurred primarily through a decline in the rate and frequency of shrinking. Structural change, technological change, demographic change and the changing incidence of warfare offer at best a partial explanation; a full understanding requires a consideration of institutional change.

There are concerns that the premature deindustrialisation experienced by low-income countries in Africa and South Asia will negatively affect their growth. This column argues that this is not the case, since services, rather than manufacturing, are driving growth in the developing world. While demographics and urbanisation can help growth in low-income countries, the low quality of physical infrastructure is a major challenge.

Conventional growth theory characterises innovation as ‘resource-saving’, in the sense that it allows the same output to be produced with fewer resources. This column introduces a sources-of-welfare growth model that also includes a measure of ‘output-saving’ innovation, which arises from the expanded scope and efficiency in consumer choice recently brought about by the Internet economy and smartphones. The findings highlight how various new kinds of intangible capital complicate the measurement of GDP.

Investment growth in emerging market and developing economies has slowed sharply since 2010. This column argues that this slowdown reflects a range of factors, including negative terms-of-trade shocks, slowing FDI inflows, weak activity, and rising private debt burdens and political risk. Policymakers can boost investment directly through public investment, and indirectly by taking measures to improve overall growth prospects and the business climate.

Austerity policies implemented during the Great Recession have been blamed for the slow recovery in several European countries. Using data from 29 advanced economies, this column shows that austerity policies negatively affect economic performance by reducing GDP, inflation, consumption, and investment. It also warns that efforts to reduce debt through austerity in the depths of the economic recession were counterproductive.

Severe recessions have been frequent among OECD countries over the past four decades. This column explores the implications of various broad types of policy to minimise the risk and frequency of such episodes for the trade-off for the growth-fragility nexus. Product and labour market policies improve growth but are essentially neutral with regards to economic risks, while better quality institutions increase both growth and economic stability. Macroprudential and financial market policies, on the other hand, entail a trade-off between growth and risk.

Inequality can be both good and bad for growth. Unequal societies may be holding back one segment of the population while helping another. This column exploits US data to argue that inequality affects negatively the future income growth of the poor and positively that of the rich. This relationship is largely driven by inequality of opportunity, which limits the growth prospects at the bottom of the income distribution.

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.

Recent research suggests a point beyond which the benefits of financial development diminish, and further development can even hurt growth. This column describes how a negative relationship between credit and growth emerged strongly after 1990 and was particularly pronounced in the Eurozone, consistent with the notion that an overgrown financial sector weakens economic growth potential. It also argues that slower growth leads to more rapid financial sector expansion. Policymakers need to be aware of the possibility that causality runs in both directions.

A new set of historical national accounts for Spain constructs estimates of output and expenditure from 1850 onwards, which means we can estimate the evolution of GDP per capita and labour productivity during this period. This column argues that the data demonstrates that GDP per capita captures long-run trends in welfare in Spain, but not short and medium run trends.

Emerging economies are substantially reliant on foreign corporate debt issuance, which has major macroeconomic implications. This column quantifies the extent to which debt issuance matters for macroeconomic performance in emerging economies, and how much macro vulnerability it has entailed. It finds evidence that a large increase in debt reliance has had a considerable effect on macroeconomic performance, but suggests that potential negative impacts on overall health of economies can be reduced in the future if policymakers have access to more and better information.

Despite lifting millions out of poverty, globalisation is facing growing political opposition. This column surveys the successes and failures of globalisation, and some of the critical policy implications. Globalisation has reached a stage where its benefits have been captured but its costs have been largely ignored. Going forward, governments need to address inequality and social inclusion, boost global investment, and restore confidence.

Free trade is under fire, with evidence documenting the distributional impacts and labour adjustment costs of trade liberalisation mounting. This column instead presents new evidence on the benefits of freer trade in terms of growth and innovation. It points to gains that could be lost if support for globalisation is not maintained.

There is much dispute over whether immigration is beneficial or detrimental to the host country, and any conclusions are often event-driven rather than evidence-based. This column explores evidence on how immigration affected economic development between 1960 and 2013 through its effect on the cultural and ethnic composition of the destination country. Cultural heterogeneity appears to have had a positive impact on economic development, and the positive effect of diversity seems to have been stronger in developing countries.

Growth in higher education has been driven by the view that human capital is essential for economic and social progress. This column uses a comprehensive international dataset covering 78 countries to show that on average, a 10% increase in the number of universities (roughly adding one more university to the average region in the data) increases a region’s income by 0.4%, with additional effects spilling over to other regions within the same country. In the UK context, the benefits of university expansion are likely to far outweigh the costs.

There has been speculation that the low employment rates for younger and less-educated workers in the US reflect a ‘new normal’. This column uses detailed new US data to project output, productivity, and employment rates over the next decade. The results indicate that US economic growth will continue to recover from the Great Recession through the resumption of growth in productivity and labour input. The recovery of employment rates for less-educated and younger workers will make an important contribution to future economic growth.

Policy proposals to offset the effects of global warming would be strengthened if we knew more about the net economic benefits of climate action relative to business-as-usual. This column argues that estimates may understate the future costs of business as usual because of heterogeneous seasonal effects, and because more business sectors than previously assumed suffer a negative impact from increased summer temperatures. The cost of inaction may be equal to one-third of the growth rate of US GDP over the next 100 years.
