Negative shocks to bank balance sheets are problematic not just for financial markets, but for employment and economic growth more widely. This column uses evidence on a bank liquidity shock in Italy in 2007-10 to show the impact on firms’ production, investment, and employment. Firms borrowing from banks with a high exposure to the shock experienced a more intense fall both in credit flows and in investment expenditure. While the credit cut has been homogeneous across borrowers, firms with easier access to external finance were able to contain the negative consequences of the drop in credit for investment.

The shifting balance between manufacturing and service industries in developed economies has significant implications for long-term growth and international trade. This column uses Japanese firm-level data to analyse the impact of ‘factoryless goods producers’ on overall productivity. As these producers specialise in tasks in which advanced economies have a comparative advantage, it is anticipated that when combined with falling production costs and trade liberalisation, they will contribute to economic growth.

Firms with greater market power can behave monopolistically, and recent research suggests that declining market competitiveness is driving income inequality. While competition authorities already measure the overall impact of their interventions by using customer savings, these measurements do not account for indirect effects of intervention. This column introduces a DSGE model to model competition policy interventions as a negative mark-up shock. Competition policy has a significant and positive impact on growth and jobs, and impacts richer and poorer households differently. Interventions have important redistributive effects that benefit the poorest in society.

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.

Free trade often comes hand in hand with economic growth. The opportunity for gain is relatively small, according to quantitative models that rely on standard static mechanisms. This column introduces a model to study the diffusion of ideas across countries as a means of increasing productivity, and a quantitative assessment of the role of trade in the transmission of knowledge. How much the transmission of knowledge will impact productivity depends on the openness of the trading countries, current stock of knowledge, and a diffusion parameter.

The US government’s ‘bailout of bankers’ in 2008-09 remains a highly controversial moment in economic policy. Many critics suggest that intervention to relieve household debt may have been more effective in stimulating economic recovery. This column suggests that without federal intervention to stabilise financial markets and recapitalise some non-bank lenders, the magnitude of the economic collapse might have been much worse. While household debt was incredibly important in reducing demand, the financial sector dislocations and the lack of credit also played a critical role.

There is a high degree of correlation between the business cycles of different countries. This is particularly the case in the Eurozone, but also among industrialised countries outside of the Eurozone. Using a two-country behavioural macroeconomic model, this column shows that the main channel for the synchronisation of business cycles is the propagation of ‘animal spirits’ – waves of optimism and pessimism that become correlated internationally.

Theory and empirical data contest the direction of causality in the relationship between economic performance and income inequality – a relationship that is of great political importance. This column uses evidence from OECD countries to show that the relationship is not linear. While some countries can improve economic performance only at the cost of increasing economic inequality, other countries can improve both economic performance and equality without such a trade-off.

By creating liquidity, banks improve the allocation of capital and accelerate economic growth. This column uses evidence from US banks between 1984 and 2006 to evaluate the impact of competition amongst banks on their liquidity creation. It finds that an intensification of competition in the banking industry materially reduces liquidity creation. Furthermore, the evidence suggests that more profitable banks experience a smaller reduction in liquidity creation because of their ability to better absorb risk. Similarly, an intensification of competition reduces liquidity creation more among small banks, who are more engaged in relationship lending.

The first century of modern Greek monetary history has striking parallels to the country’s current crisis, from repeated cycles of entry and exit from the dominant fixed exchange rate system, to government debt built-up and default, to financial supervision by West European countries. This column compares these two episodes in Greece’s monetary history and concludes that lasting monetary union membership can only be achieved if both monetary and fiscal policies are effectively delegated abroad. Understandable public resentment against ‘foreign intrusion’ might need to be weighed against their potential to secure the long-term political and economic objective of exchange rate stabilisation.

Most economists view trade as benefiting countries overall but leading to winners and losers within nations. This column summarises a recent survey about winners and losers from globalisation prepared in the context of the FP7 COEURE project. It stresses that the policy debate should focus on identifying and compensating the losers from globalisation rather than on considering protectionist measures that are detrimental to growth.

Since the Eurozone Crisis a host of monetary and fiscal instruments have been used to try to reinvigorate growth and achieve financial stability, with mixed results. Basel III’s counter-cyclical capital buffer (CCB) is one such instrument which was met with scepticism. This column uses evidence from the Swiss economy to show that given the right circumstances and political will, the CCB can achieve financial stability.

Okun’s law describes the positive empirical relationship between unemployment and the output gap. This column explores how this relationship differs depending on age and gender, taking into account different labour market institutions. Using data for 20 OECD countries over three decades, the authors find that the effect of Okun’s relationship decreases with age. Labour market institutions have similar effects on the unemployment rates of all groups, though magnitudes vary by age and gender.


The Poverty Reduction, Equity and Growth Network (PEGNet) Conference 2016 on Regional integration for Africa’s economic transformation – Challenges and opportunities will be held in Kigali, Rwanda in cooperation with the Institute of Policy Analysis and Research, IPAR-Rwanda on September 15-16, 2016.

The Conference will provide a platform for high-level dialogue between development researchers, practitioners and policy-makers working on Poverty Reduction, Inequality, Growth and other related topics in Development Economics. The two conference days will feature parallel-sessions based on invited and contributed papers and project presentations. These will be complemented by a debate, a round-table discussion, and keynote speeches by renowned speakers from academia, economic policy and development practice.

There has been much debate about the poverty impacts of economic growth and structural transformation in developing countries. This column revisits these issues using a newly constructed dataset of poverty measures for India spanning 60 years. There has been a downward trend in poverty measures since 1970, with an acceleration post-1991, despite rising inequality. Post-1991 data suggest stronger inter-sectoral linkages. Urban consumption growth came with gains to both the rural and urban poor. The primary/secondary/tertiary composition of growth has ceased to matter, as all three sectors contributed to poverty reduction.

The role of equities in Europe’s capital markets has diminished since the Global Crisis and is only slowly recovering to its prior level. This column argues that revitalising its equity markets has much to offer Europe in terms of funding business growth, creating jobs, and delivering long-term pension returns for the ageing population. The root causes of Europe’s underutilised equity markets are both cultural and regulatory. Understanding and addressing these barriers are the next necessary steps towards the full utilisation of equities.

Many argue that China has had a higher total factor productivity growth rate than India and the US since the late 1970s. This column assesses changes in China’s technology gaps between both the US and India from 1979 to 2008 with a constant elasticity of substitution production framework. The calculations suggest that the technology gap between China and the US was significantly larger than that between India and the US for the period before 2008.

Since the Global Crisis, a broad discussion about the future of securitisation has emerged. This column presents new evidence on the relationship between securitisation and economic growth. The impact of securitisation depends on the underlying type of collateral. Securitisation of business loans may encourage investment and spur economic activity, but securitisation of consumer loans may at the aggregate divert resources away from productive purposes.

Though some studies propose that entrepreneurial activity increases during conflicts, macro evidence shows that a conflict is damaging to growth. This column argues that the conflict in Afghanistan did not contribute to economic development because it caused regressive structural changes at the micro level. It reduced employment opportunities and increased self-employment in activities that have low returns. To improve the economic resilience, self-employment in activities that are less affected by conflict should be stimulated.

There is no consensus on whether foreign aid is effective in boosting the economy of the recipient country. This column suggests that there is no evidence that aid affects growth. This finding does not imply that aid is necessarily ineffective. Much of the aid is not given to affect growth in the first place, but as humanitarian aid following disasters, to fight terror, please political allies, or influence decisions in important international organisations. Such aid should thus be evaluated with its own goals in mind.
