Severe recessions have been frequent among OECD countries over the past four decades. This column explores the implications of various broad types of policy to minimise the risk and frequency of such episodes for the trade-off for the growth-fragility nexus. Product and labour market policies improve growth but are essentially neutral with regards to economic risks, while better quality institutions increase both growth and economic stability. Macroprudential and financial market policies, on the other hand, entail a trade-off between growth and risk.

An unprecedented process of deregulation took place in the banking sector in the three decades prior to the Global Crisis. This column argues that during periods of intense bank competition, financial innovation can compound the adverse effects of competition on stability. Coupled with strong competition, the significant use of one such innovation – securitisation – in the run-up to the crisis was related to high levels of bank risk.

‘Too big to fail’ is an enduring problem for financial authorities and regulators. While forbidding government bailouts may be a popular move, the strategy lacks credibility. This column examines the proposals of the Minneapolis Plan to End Too Big to Fail. The plan has many virtues that tackle systemic problems and that build on the Dodd-Frank Act’s crisis prevention and management tools. However, further analysis of the plan is still needed to ensure that its measures aren’t circumvented.

In the years since the Global Crisis, there has been substantial public opposition to taxpayer-funded bailouts of financial institutions. Reflecting this sentiment, a cornerstone of the EU’s post-crisis resolution framework is that losses be borne by private investors and creditors. This column surveys some of the details that need to be worked out before such bail-in measures can work. Effective implementation requires clear identification of the limits to bail-in. In particular, for such measures to be successful, bailout cannot be ruled out by assumption.

As with previous systemic crises, the 2007-2009 crisis has created regulatory reform, but is it adequate? This column argues that prudential regulation should consider interactions between conduct – capital, liquidity, disclosure requirements, macroprudential ratios – and structural instruments, and also coordinate with competition policy. Though recent reforms are a welcome response to the latest crisis, we do not know how effective they will be in future.

After the 2008 Global Crisis, there has been progress towards a system-wide regulatory architecture that includes a national macroprudential authority. This column describes a ‘capacity indicator’ that measures the state of macroprudential policies worldwide, including the features policymakers believe constitute a successful macroprudential policy regime. Eventually this index may be used to establish whether these macroprudential policy innovations have been successful.

The ECB is under fire from all sides for its inability to stimulate Europe's economies. This column puts the case for an informal European ‘praesidium’ within the Eurogroup to coordinate wider stimulus and reform measures. This will inevitably lead to the appointment of a European finance minister – the Eurozone's equivalent of Alexander Hamilton, the first Treasury Secretary in the history of the US.

Governments and regulators are commonly assumed to offer special protection to the stakeholders of large financial institutions during financial crises. This column measures the ex ante cost of implicit shareholder guarantees to financial institutions in crises, and suggests that such protection affects small and large financial institutions differently. The evidence suggests that in the event of a financial crisis, stock investors price in the implicit government guarantees extended to large financial institutions, but not to small ones.

Finance plays a key role in growth by connecting savers and investors, but it can also be a source of crises. This column discusses whether there has been enough finance to enable productive investments. UK non-financial companies appear to have enough internal funds to cover all their investment taken as a whole, but the evidence suggests that small firms face shortfalls. The column also pleads for the development of new and better data sources to help measure the supply of finance that can be used to exploit productive investment opportunities.
The course will consider alternative macroeconomic frameworks with financial frictions to under-stand financial crisis, business cycles and public policy. There will be an brief historical overview of financial crises and basic financial accelerator models which emphasizes the interaction between borrowing constraint, asset price and aggregate production.
It will then be introduced liquidity constraint to examine the business cycles and monetary policy. Finally, the course will present financial intermediaries and government to study banking crisis, credit policy and macro prudential policy. By developing these frameworks, the training aims to understand the recent financial crisis and the roles of public policies.

There has been much research on the effects of banking crises, but corporate resilience to systemic crises is less well understood. This column uses data from 34 countries from 1990 to 2011 to analyse the role of social trust – societal expectations that people will behave honestly and cooperatively – in building corporate resilience. It finds that social trust facilitates access to trade credit, and dampens the harmful effects of crises on corporate profits and employment.

The recent reversal of capital flows to emerging markets has pointed to the continuing relevance of the sudden stop problem. This column analyses the sudden stops in capital flows to emerging markets since 1991. It shows that the frequency and duration of sudden stops have remained largely unchanged, but that global factors have become more important in their incidence. Stronger macroeconomic and financial frameworks have allowed policymakers to respond more flexibly, but these more flexible responses have not guaranteed insulation or significantly mitigated the impact.

One of the many impacts of the Global Crisis was on stress levels, and these can be a risk factor for adverse birth outcomes. This column shows that exposure to the Crisis resulted in a significant reduction in the birth weight of babies in Iceland, comparable in size to the effect of smoking during pregnancy. The full costs of poor health at birth as a result of the Crisis will not materialise until the children exposed in utero become adults.
Adair Turner, 19 March 2016
Prior to the Global Crisis, modern macroeconomics largely ignored the details of the financial system, and favoured mathematical precision and elegance at the expense of realism. So argues Adair Turner in this Vox Talk. He also explains the key arguments in his book, ‘Between Debt and the Devil: Money, Credit and Fixing Global Finance’: that most credit is not needed for economic growth but rather drives real estate booms and busts; and that sometimes it’s better to print your way out of financial crises.

It has been claimed that recessions as a result of a financial crisis tend to last longer than normal recessions. This column asks whether early intervention to help distressed banks during financial crises is effective in mitigating the consequences of financial distress. The evidence suggests that decisive and early recapitalisation of banks can shorten recessions by several years and help speed up recovery.

It is widely agreed that the Global Crisis qualifies as a period of ‘systemic’ financial stress. However, identifying and classifying other similar periods is challenging. This column presents a new framework for a transparent and objective identification of systemic financial stress episodes, beyond the expert-selected stress events available so far. The approach is applied to 27 EU countries to successfully identify episodes of financial stress.

Recent events in Europe provide ample evidence that the political aftershocks of financial crises can be severe. This column uses a new dataset that covers elections and crises in 20 advanced economies going back to 1870 to systematically study the political aftermath of financial crises. Far-right parties are the biggest beneficiaries of financial crises, while the fractionalisation of parliaments complicates post-crisis governance. These effects are not observed following normal recessions or severe non-financial macroeconomic shocks.

Economists were early critics of the design of the Eurozone, though many of their warnings went unheeded. This column discusses some fundamental design flaws, and how they have contributed to recent crises. National booms and busts lead to large external imbalances, and without individual lenders of last resort – national central banks – these cycles lead some members to experience liquidity crises that degenerated into solvency crises. One credible solution to these design failures is the formation of a political union, however member states are unlikely to find this appealing.

The risk that asset price bubbles pose for financial stability is still not clear. Drawing on 140 years of data, this column argues that leverage is the critical determinant of crisis damage. When fuelled by credit booms, asset price bubbles are associated with high financial crisis risk; upon collapse, they coincide with weaker growth and slower recoveries. Highly leveraged housing bubbles are the worst case of all.

There has been much talk about using macroprudential policy to manage systemic risk and reduce negative spillovers, but there is little agreement on how it could be operationalised. This column highlights the findings of a new book on the topic and offers a framework for operationalising macroprudential policy. Macroprudential measures, together with higher capital requirements, could be used to tame the build-up of leverage and credit booms in order to prevent financial crises.
