Ben Bernanke famously quipped that monetary policy works in practice, but not in theory. This column bridges the gap between practice and theory in assessing how central banks can influence both of them by intervening in asset markets. To the extent that asset market volatility is driven by shifts in beliefs, the central bank should aim to eliminate that volatility by engaging in countercyclical unconventional monetary policy, which would end up reducing the risk premium.

The blockchain technology underlying Bitcoin and other cryptocurrencies is attracting growing interest. This column argues that if transactions facilitated by this technology become pervasive, it will have implications for the conduct (and success) of central bank monetary policy. Central banks should embrace the technologies that underpin cryptocurrencies, or risk being cut out from intermediation and surveillance and also risk payment service providers moving to other currency areas with an institutional environment that is more appealing for buyers and sellers.

The pre-crisis consensus was, and remains, very strong – the business cycle would be managed by monetary policy, while fiscal policy would focus solely on debt sustainability. In a world of zero interest rates, however, fiscal policy has to contribute to supporting aggregate demand and protecting against deflationary risks. This column outlines three ways in which a well-designed expansionary fiscal policy stance can contribute to better economic outcomes.

Some economists see helicopter money as a free lunch, because it can prompt growth without requiring higher debt financing. This column argues that if there are costs associated with the permanent injection of cash into the economy, they would diminish its effectiveness.

Today's unconventional central bank policies have historical precedent. One example is the suspension of convertibility of banknotes into gold by the Bank of England between 1797 and 1821. This column argues that, although there were important differences between then and now, it demonstrates that bank reputation and interaction between bank and state are vital to the success of unconventional policies. Also, short-term unconventional policies may persist long after a crisis has passed.

Is it possible that the global financial cycle is driven by US monetary policy? In this video, Hélène Rey explains how US monetary policies affect global financial cycles. This video was recorded at the ASSA Meetings in San Francisco in January 2016.

International financial spillovers from emerging markets have increased significantly over the last 20 years. This column argues that growing financial integration of emerging economies is more important than their rising share in global trade in driving this trend, that firms with lower liquidity and higher borrowing are more subject to spillovers, and that mutual funds are amplifying spillover effects. Policymakers in developed economies should pay increased attention to future spillovers from emerging markets, particularly from China.

Recent research into how monetary policy frameworks incorporate risks to financial stability has shown that policy affects both financial conditions and financial vulnerabilities that amplify negative shocks. This column argues that looser monetary policy improves financial conditions, but can in some situations worsen vulnerabilities through incentives for financial sector risk-taking and non-financial sector borrowing. Policymakers face an intertemporal trade-off between financial conditions and vulnerabilities which may impact a cost-benefit analysis of monetary policy.

The Global Crisis has renewed debate about the relationship between short-term interest rates and bank risk taking. Theory offers ambiguous and conflicting predictions. This column explores the relationship using confidential bank-level data from the US. Bank risk taking is found to be negatively associated with short-term interest rates, and this is more pronounced for highly capitalised banks. These findings can help inform the design of monetary policy.

The zero lower bound policy for nominal interest rates was implemented to stimulate sluggish economic growth and boost employment. This column explores whether this policy had unintended effects on the money market fund industry. Traditionally enjoying relatively low and safe returns, money market funds could respond to the low interest rate environment by either exiting the market or changing product offerings and accepting higher portfolio risk. The results show evidence of both, and point to an important but neglected channel for monetary policy transmission.

Brexit has raised the possibility of a recession on both sides of the Atlantic. Unable to use traditional remedies like monetary or fiscal policy stimulus, policymakers may consider automatic fiscal stabilisers. This column examines the impact of automatic stabilisers through social insurance on the business cycle, and how its impact can be used to mitigate recession. Unemployment insurance or food stamps would be better than progressive taxes at stimulating aggregate demand. The main economic channels policymakers must consider are those related to risk and precautionary savings.

Despite facing many of the same challenges, Germany’s current macroeconomic policy is substantially different to those of other countries, in part due to the economy legacy of Walter Eucken. This column considers the economic policy of Hjalmar Schacht, whose ‘MEFO-bills’ monetary solution ended the years of economic struggle caused by the Treaty of Versailles’ reparations commitments. By tying the bills to output, Schacht was able to stimulate output, and eliminate unemployment. This historical implication has clear modern-day implications, with parallels to ‘helicopter money’ policy and Italy’s recent ‘fiscal money’ proposal.


The global financial crisis has had a profound impact on output and productivity in advanced and emerging economies. In response, policymakers around the world have acted boldly with monetary policy, macro-prudential policy and regulation.

Is productivity being held back by financial factors - such as the lack of long term finance for long term investment - or is productivity being held back by real economy factors, such as globalisation and demographics? The recent crisis has also spurred a reassessment of the relationship between the level (and type) of finance and growth. Could weak productivity growth owe in part to wasteful investment spending or an undersupply of financial services? How does the mix of early and late stage financing drive investment and productivity? This conference aims to bring together perspectives on these big questions, as they will provide important guidance for future policy actions.


The objective of this course is to present empirical applications (as well as the research methodologies) of relevant questions for both banking theory and policy, mainly related to Systemic Risk, Crises, Monetary Policy and Risk taking behaviour. An important objective is to understand scientific papers in empirical banking; to accomplish this objective, emphasis is placed on illustrating research methodologies used in empirical banking and learning the application of these methodologies to selected topics, such as:

- Securities and credit registers; large datasets

- Fire sales, runs, market and funding liquidity, systemic risk

- Risk-taking and credit channels of monetary policy

- Moral hazard vs. behavioral based risk-taking

- Secular stagnation, banking and debt crises

- Interbank globalization, contagion, emerging markets, policy

The idea that the global economy has entered a low-growth equilibrium appears to have gained acceptance. This column argues that this ‘New Normal’ never was, isn’t, and should be replaced by the ‘New Abnormal’. Far from being an equilibrium, the low growth recorded in the West since the nadir of the financial crisis in 2009 has only been achieved by progressively more aggressive and unprecedented monetary policy actions in response to a series of panic attacks in the financial markets. The aftershocks of the crisis are colliding with a series of structural changes which leave the global economy in a state of latent instability.

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.

Both the US and the Eurozone reacted to the Global Crisis by injecting liquidity and loosening monetary policy. This column argues that despite the similarities in the behaviour of bank credit, the behaviour of bank reserves has been quite different. In particular, while US bank reserves have been on an uninterrupted upward trend since Lehman’s collapse, EZ bank reserves have fluctuated markedly in both directions. At the source, this is due to differences in the liquidity injections procedures between the Eurozone and the Fed.

Helicopter money is frequently in the headlines but frequently misunderstood. This column reviews the VoxEU columns that have – since 2010 – provided research-based policy analysis of this ‘beyond unconventional’ policy.

By the end of 2013, growth in Latin America had begun to decelerate. The ensuing policy responses to this have differed across countries. This column uses data from the past 40 years to analyse policy responses to economic distress in the region. On average, countercyclical policy responses to crises have been more common over the last 15 years than previously. Latin America thus appears to have graduated in terms of monetary and fiscal responses to crises. But there is still a great deal of heterogeneity across countries in the region, and they must continue to build sound and credible fiscal and monetary institutions.

The ECB’s response to the Crisis – not providing stimulus to the Eurozone economy when it needed it, and allowing it to slip into a low inflation trap – is a reflection of the monetary union’s faulty architecture. This column recalls a 1998 manifesto from several distinguished scholars that warned EZ policymakers of the potential consequences of a misguided policy framework. Two sets of issues need to be critically addressed by current EZ policymakers: its objectives and instruments.
