Macroeconomic policy

For decades, the UK government has been very careful in ensuring a low-risk status for its public and private debt. This column warns that if the UK opts to leave the EU, uncertainty over the implications of Brexit would put this low-risk status in jeopardy. A depreciation of the pound could well generate an export boom, but this would not compensate for the damage to internal demand and to the UK’s ability to access external financing of its deficits.

The threat to the financial system posed by cyber risk is often claimed to be systemic. This column argues against this, pointing out that almost all cyber risk is microprudential. For a cyber attack to lead to a systemic crisis, it would need to be timed impeccably to coincide with other non-cyber events that undermine confidence in the financial system and the authorities. The only actors with enough resources to affect such an event are large sovereign states, and they could likely create the required uncertainty through simpler, financial means.

At first sight, it is difficult to explain why the macroeconomic debate and macroeconomic policy in Germany differ considerably from other countries, despite the same academic textbooks and models being used as elsewhere. This column explains how a specific paradigm of macroeconomics, developed by Walter Eucken and diametrically opposed to Keynesian economics, is behind the German formal theoretical apparatus. The success of German macroeconomic policy can be attributed to the openness of the German economy, which allows it to benefit from macroeconomic policies pursued in other major countries.

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.

The IMF’s latest Global Financial Stability Report devotes for the first time a chapter to the systemic risks potentially associated with the insurance sector and how regulatory bodies should respond. This column examines the key points and proposes a way forward for the global regulatory framework for insurance. In particular, it argues for the importance of not treating the sector in the same way as the banking sector as the two operate very different business models. Similarly, for an activity-based approach, a regulatory focus on just nine ‘systemically important’ insurers rather than the sector as a whole is flawed.
