The relationship between finance and growth has recently returned to the top of the policy research agenda, with several papers questioning earlier results indicating a positive link. This column suggests a different interpretation of the early findings. While there can be too much finance, as many countries have found out in recent crises, this does not imply that there is too much financial development.

The large international imbalances accumulated in the Eurozone have proven difficult to unwind during the recent Crisis. This column argues that market reforms had a role in generating current account imbalances, and that patterns of relative labour market regulation could be equally important in the aftermath of the Crisis.

The Global Crisis put to the fore the possibility that the relationship between financial development and output growth may be non-linear. This column presents new evidence on the issue using data on output growth of ten sectors from Latin America and East Asia. The authors find large differences between the two regions in terms of the impact of financial depth on sectoral growth, and validate the negative impact of financial deepening on output growth in several sectors. The results confirm that the impact of financial development on sectoral growth may indeed be non-linear – i.e. it may promote growth only up to a point.

Remittances are one of the most important financial flows to developing countries – more than three times the level of official development assistance. This column presents recent research on remittance flows from Italy. Their limited volatility and countercyclical behaviour with respect to macroeconomic conditions in the recipient country help mitigate developing countries’ vulnerability to external shocks. Better access to financial services for migrants can foster remittance flows.

A well-functioning financial system is critical for economic growth. However, some studies find a negative relationship between the two at high levels of financial development. This column discusses why this is the case and suggests some policy implications. It argues that reforms that refocus the financial system on enterprise credit and on internalising the downside risks can be beneficial.

Financial liberalisation has been controversial among academics and policymakers as it is not clear whom the benefits of expanded credit allocation accrue to. Using time and state-level variation across Indian states, this column finds strong evidence that financial deepening reduces rural poverty, especially among the self-employed. Financial deepening is also found to be associated with an inter-state migration trend from rural areas into the tertiary sector in urban areas.

For some commentators, the recent financial crises are a sign that financial development has gone too far. Yet there are still countries where such concerns are the stuff of dreams. This column focuses on why the level of financial development in poor countries remains so low and what policymakers can do about it.

Financial systems support and spur economic growth. But does financial innovation foster financial development? While recent innovations have done damage, this column says the long-run story is that financial innovation is essential for economic growth.

Recent sovereign defaults in developing countries have put severe strain on the defaulting country’s banking system. This column argues that these events teach us how the development of private financial markets plays a critical role in reducing the risk of government default and thus in supporting public borrowing.

Can financial sector reform help bring informal firms into the formal sector? This column examines over 22,000 firms from 43 countries. Firms in countries with a credit registry are 20% less likely to evade taxes, and the tax evasion ratio in such countries is 11% lower.

What do countries need for sustainable financial development? This column argues that protection of property rights is necessary but not sufficient. Using a sample of 160 countries from 1960 to 2005, it finds that checks and balances on power and political stability are the vital ingredients.

Financial interconnectedness across countries has reached unprecedented levels – but what has driven this change? This column finds that financial deregulation is responsible for 16 percentage points of the increase in financial development, but openness to trade and the size of government off-set one another. This is because the structural association between trade openness and financial development is mildly negative.

Why have emerging economies weathered the crisis better than advanced countries? This column summarises a session given by Alan Winters, Saul Estrin, Thorsten Beck, and organised by Nauro Campos at the Royal Economic Society annual conference in March 2010. The contributions argue that the crisis may have long-lasting effects on migration, foreign direct investment, and financial development in Africa.

How does financial development affect macroeconomic outcomes? Previous studies have relied on aggregate measures. This column introduces a data set that distinguishes between lending to enterprises and households and investigates the consequences for economic growth, income inequality, and consumption smoothing.

Financial institutions and sensible regulation have made great strides in emerging markets, but this column warns that the current crisis may cause emerging markets to re-enact internal battles for their economic souls that we thought had been conclusively decided. Developed country leaders should not fan the flames of anti-market sentiments.
