Institutions are known to play a powerful and enduring role in countries’ divergent levels of economic development. This column presents evidence that institutions matter for within-country inequality, too. In Brazil, changes in export prices and export tax revenues led to an increase in education spending in states that experienced commodity booms, which increased the number of schools and improved educational outcomes such as literacy rates. However, the effect was limited in states where slavery was predominant in colonial times.

Whereas textbook macroeconomic theory suggests that output should return to potential after a recession, there is mounting evidence that deep recessions have highly persistent effects on output. This column reports estimates of the long-term damage caused by the Great Recession. In most countries in the sample, the loss of potential output – 8.4% on average – has been almost as large as the loss of actual output. In the countries hit hardest by the recession, the growth rate of potential output is much lower today than it was before 2008.

The CEPR Business Cycle Dating Committee recently concluded that there is not yet enough evidence to call a business cycle trough in the Eurozone. Instead, the committee has announced a 'prolonged pause' in the recession. This Vox Talk discusses the possible directions that this situation could lead to and questions whether the Great Recession has harmed the Eurozone’s long-term growth prospects to the extent that meagre growth could become the 'new normal'.

The simplest business cycle dating algorithm declares recessions over after two consecutive quarters of positive GDP growth. By that metric, the Eurozone recession has been over since 2013Q1. This column argues that growth and improvements in the labour market have been so anaemic that it is too early to call the end of the Eurozone recession. Indeed, if this is what an expansion looks like, then the state of the Eurozone economy might be even worse than economists feared.

Investment in the Eurozone is forecast to remain below trend until 2015, with a particularly large shortfall in the periphery. Low investment reduces aggregate demand, thus lowering short-term growth, and it also hampers medium-term growth through its effect on the capital stock. This column highlights three causes of low Eurozone investment – reduced public investment, financial fragmentation, and heightened uncertainty – and proposes a series of remedies.

Thomas Piketty’s new book has been widely praised for its empirical contribution, but his prediction of rising inequality rests on economic theory. This column argues that Piketty’s pessimistic forecast is based on an extreme – and unrealistic – assumption about households’ saving behaviour. According to standard theory, the wealth–income ratio would increase only modestly as growth falls, so declining growth would not be a powerful force for generating high inequality.

Immigrants to the US are drawn from both ends of the education spectrum. This column looks at the effect of highly educated immigrants – in particular, those with degrees in Science, Technology, Engineering, or Mathematics – on total factor productivity growth. The authors find that foreign STEM workers can explain 30% to 60% of US TFP growth between 1990 and 2010.

Young firms are known to play a central role in job creation. This column presents the results of a new OECD project on the dynamics of employment (DynEmp) based on an innovative methodology using firm-level data. It confirms that young firms play a central role in creating jobs, and in enhancing growth and innovation. Public policies can help by enabling firms to experiment, and by fostering the reallocation of resources towards the most productive firms. Structural reforms to product, labour, and capital markets, as well as bankruptcy laws that do not overly penalise failure, are particularly relevant.

Many analysts view democracy as a neutral or negative factor for growth. This column discusses new evidence showing that democracy has a robust and sizable pro-growth effect. The central estimates suggest that a country that switches from non-democracy to democracy achieves about 20% higher GDP per capita over the subsequent three decades.

The concept of environmental capital is throughly entrenched in policy dicussions but largely missing from mainstream economic curriculums. This column argues environmental externalities, climate change, and constraints on natural resources will constantly and deeply affect humankind’s future. The teaching of economics, especially growth economics, should stop ignoring them.

Excessive short-termism is always a problem for policy, but the Global Crisis has brought it sharply into focus. This column introduces a report that discusses how a shift to longer-term solutions is necessary and possible. A key message is that businesses as well as governments need to take a longer-term view. The report identifies ways to overcome the current impasse in key economic, climate, trade, security, and other negotiations.

Inequality has the potential to undermine growth. However, greater redistribution requires higher tax rates, which reduce incentives to work and save. Moreover, the evidence that inequality is bad for growth might simply reflect the fact that more unequal societies choose to redistribute more, and those efforts are antithetical to growth. This column presents evidence from a new dataset on pre- and post-tax inequality. The authors find that income equality is protective of growth, and that redistributive transfers on average have little if any direct adverse impact on growth.

Urbanisation and GDP per capita are positively correlated across countries. However, when the sample is restricted to developing countries, urbanisation and growth are more loosely related – particularly in Africa. CEPR Policy Insight 71 argues that the low share of manufacturing in developing-country cities may help to explain this discrepancy. Strengthening urban finances, embracing technology, improving skills, and stimulating the formal sector will help cities to promote growth. Since decisions affecting urban development can have lasting impact, longer-term planning deserves greater attention than it is currently receiving.

Financial development and growth have long been linked. This column argues that there remain fundamental lacunae in our understanding of the finance-growth nexus. Three main areas for future research are identified: aid, institutions and technology.

The strong rebound of manufacturing production following the Great Recession of 2008–09 has generated renewed interest in the sector among analysts and policymakers. This column argues that a detailed look at the data suggests that claims of a US manufacturing renaissance are unwarranted. Yet, there remain factors that could support a greater contribution from the manufacturing sector to overall US growth in the years ahead.

There is a strong link between entrepreneurship and growth – young firms were responsible for almost all net job creation in the US economy over the last 30 years. This column presents new research into the responsiveness of firms of different ages to investment opportunities. Firms aged 0–23 months create about twice the total number of new jobs in response to local income shocks than firms that are more than six years old.

Economists have found that large-scale infrastructure investments tend to increase economic growth and reduce poverty. However, there has been relatively little research on the effects of smaller, more targeted investment projects. This column discusses recent research on the effects of the US Rural Electrification Administration, which provided subsidised loans for connecting farms to the electric grid. Counties that received electricity through the REA witnessed smaller declines in agricultural productivity, smaller declines in land values, and more retail activity than similar counties that did not.

The link between higher national income and higher national life satisfaction is critical to economic policymaking. This column presents new evidence that the connection is hump-shaped. There is a clear, positive relation in the poorer nations and regions, but it flattens out at around $30,000–$35,000, and then turns negative.

A key question in economics is whether poor countries will automatically close the income gap with rich countries. However, different empirical methods yield different answers – growth regressions suggest convergence, whereas tests of distribution dynamics suggest divergence. This column discusses recent research that reconciles these two strands of the literature. It extends the benchmark growth regression model to include a parameter that determines the share of new technologies a country can adopt each year. The result is that, although each country converges to a growth path, the growth paths themselves may diverge.
