Sourcing foreign inputs to improve firm performance
Maria Bas, Vanessa Strauss-Kahn, 14 July 2014
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.
Should trade policy fight or promote imports of intermediate inputs? While several studies have shown the recent increase in imports of intermediate goods, their role in shaping domestic economies is not yet completely understood. Following the work of Feenstra and Hanson (1996), a large literature focuses on the impact of imported intermediate inputs on employment and inequality.

Institutions, trade shocks, and regional differences in long-run educational and development trajectories
André Carlos Martínez, Aldo Musacchio, Martina Viarengo , 9 July 2014
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.
Understanding the determinants of long-run socio-economic development is a major concern for academics and policymakers in many countries around the world.

Globalisation, job security, and wages
Kerem Cosar, Nezih Guner, James R Tybout, 7 July 2014
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.
How does increased openness to international trade affect workers’ wages and job security? This question is central to the public debate concerning the effects of globalisation, but convincing quantitative answers have been difficult to come by. One fundamental reason is that major trade liberalisation episodes have often coincided with labour reforms (Heckman and Pages 2004).

Capital is not back: A comment on Thomas Piketty’s ‘Capital in the 21st Century’
Odran Bonnet, Pierre-Henri Bono, Guillaume Camille Chapelle, Étienne Wasmer, 30 June 2014
Thomas Piketty’s claim that the ratio of capital to national income is approaching 19th-century levels has fuelled the debate over inequality. This column argues that Piketty’s claim rests on the recent increase in the price of housing. Other forms of capital are, relative to income, at much lower levels than they were a century ago. Moreover, it is rents – not house prices – that should matter for the dynamics of wealth inequality, and rents have been stable as a proportion of national income in many countries.
The impressive success of Thomas Piketty’s book (Piketty 2014) shows that inequality is a great concern in most countries. His claim that “capital is back”, because the ratio of capital over income is returning to the levels of the end of the 19th century, is probably one of the most striking conclusions of his 700 pages.

Is Piketty’s ‘Second Law of Capitalism’ fundamental?
Per Krusell, Tony Smith, 1 June 2014
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.
Over the last several weeks, we have thought quite a bit about the main message in Thomas Piketty’s now world-famous book, Capital in the Twenty-First Century (Piketty 2014). We have also discussed it at great length with colleagues.

Global income distribution: From the fall of the Berlin Wall to the Great Recession
Christoph Lakner , Branko Milanovic, 27 May 2014
Since 1988, rapid growth in Asia has lifted billions out of poverty. Incomes at the very top of the world income distribution have also grown rapidly, whereas median incomes in rich countries have grown much more slowly. This column asks whether these developments, while reducing global income inequality overall, might undermine democracy in rich countries.
The period between the fall of the Berlin Wall and the Great Recession saw probably the most profound reshuffle of individual incomes on the global scale since the Industrial Revolution.

How unequal is the European Parliament’s representation?
Anish Tailor, Nicolas Véron, 21 May 2014
The European Parliamentary elections are conducted under rules that give voters power that varies with their nationality. This inequality is higher than in European and US national elections, as well as in large emerging-market democracies like Brazil, India, and Indonesia. Making the distribution more equal would be simple, but would require a change in the EU Treaties.
This week’s European Parliament election (22–25 May) has several unprecedented features. Most importantly, the main pan-European parties are fielding lead candidates for European Commission President.

Falling real wages in the UK
David Blanchflower, Stephen Machin, 12 May 2014
The pain of the UK’s Great Recession has been spread more evenly than previous downturns, with falling real wages across the distribution. This column asks why this happened, how it compares with the US experience, and what the prospects are for recovering lost wage gains.
There have been unprecedented falls in real wages in the UK since the start of the recession triggered by the financial crisis of 2008. This did not happen in previous economic downturns – median real wage growth slowed down or stalled, but it did not fall.

How to address inequality
Jeffrey Frankel, 29 April 2014
Awareness of inequality is rapidly rising. This column argues that commentators should focus on identifying the policies that are best suited to improving income distributions efficiently, and the politicians that support them. It is not sufficient to sound the alarm about inequality and the political reach of the super-rich.
Inequality has received a lot of attention lately, particularly in two arenas where it had not previously received as much: American public debate and the International Monetary Fund.

Human capital and income inequality: Some facts and some puzzles
Amparo Castelló-Climent, Rafael Doménech, 23 April 2014
Most developing countries have made a great effort to eradicate illiteracy. As a result, the inequality in the distribution of education has been reduced by more than half from 1950 to 2010. However, inequality in the distribution of income has hardly changed. This column presents evidence from a new dataset on human capital inequality. The authors find that increasing returns to education, globalisation, and skill-biased technological change can explain why the fall in human capital inequality has not been sufficient to reduce income inequality.
The rise of income inequality in many countries from 1985 onwards, and particularly during the recent crisis, has prompted a current debate on the causes and consequences of higher inequality and its effects on future growth (see, for example, OECD 2011, IMF 2014, or Ostry et al. 2014).
