Determining ‘currency value’ is a century-old topic on which there is little consensus among economists. This column proposes a novel way of adjusting real exchange rates for key country-specific fundamentals to obtain better gauges of currency valuation levels. Adjusting for productivity, export quality, foreign assets, and output gaps is shown to isolate information related to currency risk premia across countries. This can serve as a more precise input into investment and policy decisions.

The global financial crisis has had a profound impact on output and productivity in advanced and emerging economies. In response, policymakers around the world have acted boldly with monetary policy, macro-prudential policy and regulation.
Is productivity being held back by financial factors - such as the lack of long term finance for long term investment - or is productivity being held back by real economy factors, such as globalisation and demographics? The recent crisis has also spurred a reassessment of the relationship between the level (and type) of finance and growth. Could weak productivity growth owe in part to wasteful investment spending or an undersupply of financial services? How does the mix of early and late stage financing drive investment and productivity? This conference aims to bring together perspectives on these big questions, as they will provide important guidance for future policy actions.

Many advanced economies have experienced a productivity slowdown in recent years. Italy, however, has been experiencing such a slowdown since the mid-1990s. This column provides a detailed analysis of Italy’s patterns of misallocation over this period. Firms in the Northern regions, as well as large firms, have experienced the sharpest increase in resource misallocation. To tackle the resulting productivity slowdown, reforms need to address unemployment benefits and higher education, as well as encouraging investment in intangible assets.

The ‘great inventions’ view of productivity growth ascribes the excellent growth from 1920 to 1970 in the US to a handful of advances, and suggests that today poor productivity performance is driven by a lack of breakthrough discoveries. This column argues instead that the development of an effective governmental infrastructure in the 19th century accounted for a major part of US technological progress and prominence in this period. Infrastructure design thus appears to have the power to reinvigorate technological progress.

Americans have long debated when the country became the world’s economic leader, when it became so unequal, and how inequality and growth might be linked. Yet those debates have lacked the quantitative evidence needed to choose between competing views. This column introduces evidence on American incomes per capita and inequality for two centuries before World War I. American history suggests that inequality is not driven by some fundamental law of capitalist development, but rather by episodic shifts in five basic forces: demography, education policy, trade competition, financial regulation policy, and labour-saving technological change.

Cluster development programmes (CDPs) aim to support industrial clusters of agglomerated firms to achieve higher productivity and sustainable development. Such programmes have been prominent in Latin America over the past decade, but there have been few impact evaluations. This column presents the findings from an evaluation of Latin American CDPs. Various case studies show positive medium-term effects of the programmes on employment, exports, and wages. CDPs are also found to have positive spillover effects on untreated firms, and to improve the network connectivity and technology-transfer ties between firms.

There are strong links between the nature of education in a country and its political institutions, and an individual’s education can impact their lifetime labour market choices. This column examines how being educated under a socialist regime impacts individuals in a free labour market. Using data on students from East and West Germany in the 1970s, it finds that a socialist regime education led to a larger spread in labour market outcomes – more of these individuals were not employed, but conditional on being employed, had higher wages and a higher probability of achieving a professional status in the East.

The development accounting literature tries to account for cross-country output per worker differences by taking stock of inputs per worker. The data employed are often measured without great precision, however, making comparisons difficult. This column presents a new, internationally comparable dataset of average hours worked per adult across the world income distribution. Adults in poor countries are found to work a lot more and with lower productivity than those in rich countries. The findings suggest that those from poorer countries are not only ‘consumption poor’, but also ‘leisure poor’.

Behavioural economics has made many gains in recent years, but much uncertainty persists about the effectiveness of different behavioural interventions. This column uses data from a large-scale experiment to find the relative effectiveness of multiple treatments within one setting, and to gauge the accuracy of academic experts’ forecasts of responses. It finds monetary incentives are strong motivators, non-monetary psychological inducements are moderately effective, and results using behavioural factors are generally consistent with models of social and time preferences. Further, the interviewed experts correctly anticipate several results, including the effectiveness of psychological inducements, but fail to predict other important features.

Optimising the allocation of factors of production improves productivity. In India, where evidence suggests land is severely misallocated to inefficient manufacturing firms, access to financing is disproportionately tied to access to land. This column examines the link between the misallocation of land and access to capital through financial markets. A very strong positive correlation emerges between the two, consistent with the fact that land and buildings can provide strong collateral support for accessing finance from the credit market.

Spain enjoyed substantial growth in the decade prior to the Global Crisis, despite declining aggregate productivity. Recent research blames the poor productivity on different forms of a ‘financial resource curse’. This column argues that resource misallocation was particularly severe due to corruption and crony capitalism. This suggests future growth will require serious political reforms.

The effect of an individual’s place of residence on their life chances has long been discussed in public policy debates. This column uses British Household Panel Survey data to assess whether birthplace plays a role in determining future earnings. On average, an individual born in London in the 1970s will earn around 7% more than an individual of the same age and gender born in Manchester; who in turn will earn 5.5% more than an individual born in Cardiff. Parental sorting and the influence of birthplace in decisions about current location both play a role in explaining this effect.

Recent research has found that certain firms increase their innovative activity during periods of falling demand. This column investigates this puzzle by analysing how Japanese firms adjust their product mix over the business cycle. During transitions from recession to expansion, firm-level product churning – that is, simultaneously adding and dropping products – increases by 25%. The findings lend support to the ‘trapped factor’ model, in which negative demand shocks see the redeployment of underemployed resources towards innovation processes.

Patent filings have proliferated globally in recent years. While some may see this as a direct consequence of increased innovation, this column uses evidence from the UK to show that patent thickets – patents belonging to many companies protecting overlapping technology – reduce innovation. Patent thickets decrease entry (i.e. first time patenting in an area) by 20%, which is substantial bearing in mind that the average probability of entry into a technology area is only about 1.5%.

Misalignments of real exchange rates continue to be the most visible and painful symptom of asymmetric shocks within the Eurozone. An important factor behind such misalignment is the difference in national wage formation and bargaining systems, especially between core and periphery members. This column argues that all members need to have institutions that ensure wage developments are in line with productivity developments. This would eliminate an important source of asymmetric behaviour and reduce resistance to EZ-wide fiscal mechanisms capable of absorbing asymmetric shocks.

Digital technologies are having dramatic impacts on consumers, businesses, and markets. These developments have reignited the debate over the definition and measurement of common economic statistics such as GDP. This column examines the measurement challenges posed by digital innovation on the economic landscape. It shows how existing approaches are unable to capture certain elements of the consumer surplus created by digital innovation. It further demonstrates how they can misrepresent market-level shifts, leading to false assessments of production and growth.

The Great Depression is considered one of the darkest times for the US economy, but some argue that the US economy experienced strong productivity growth over the period. This column reassesses this performance using improved measures of total factor productivity that allow for comparisons of productivity growth in the Depression era and in later decades. Contrary to Alvin Hansen’s gloomy prognosis of secular stagnation, the US economy was in a very strong position during the 1930s by today’s standards.

Reorganisation doesn’t always create a more efficient and effective firm. This column assesses the extent to which a firm’s physical productivity varies as a result of reorganisation. The results suggest significant variation. For policymakers, studying and understanding the internal organisational responses of firms to firm-specific and economy-wide shocks is essential to understanding the level and distribution of productivity in an economy.

A city’s metropolitan governance structure has a critical influence on the quality of life and economic outcomes of its inhabitants. This column quantifies the impact of governance on productivity using data from five OECD countries. Administrative fragmentation, which complicates policy coordination across a city, has a negative effect on individual productivity. This finding, combined with benefits from good governance such as improved transport and lower pollution levels, highlights the importance of well-designed metropolitan authorities.

Inequality, both in firm revenues and wages, varies greatly across sectors, has increased over time and is positively correlated to export opportunities. To explain these observations, this column propose a new theory in which firms’ investment at the entry stage affects the variance of the possible realisations of their productivity. It suggests that export opportunities and competition, besides reallocating resources across existing firms, increase the value of technological heterogeneity. This hints to a new powerful channel through which globalisation is making firms and wages more unequal.
