The Trouble With Financial Bubbles

Central bankers remain divided about when they should seek to prick asset bubbles, with some arguing that maintaining financial stability is too complex an objective. But we need our central bankers to make difficult decisions that require balancing potentially conflicting objectives, even if they are not always right.

LONDON – Very soon after the magnitude of the 2008 financial crisis became clear, a lively debate began about whether central banks and regulators could – and should – have done more to head it off. The traditional view, notably shared by former US Federal Reserve Chairman Alan Greenspan, is that any attempt to prick financial bubbles in advance is doomed to failure. The most central banks can do is to clean up the mess.

Bubble-pricking may indeed choke off growth unnecessarily – and at high social cost. But there is a counter-argument. Economists at the Bank for International Settlements (BIS) have maintained that the costs of the crisis were so large, and the cleanup so long, that we should surely now look for ways to act pre-emptively when we again see a dangerous build-up of liquidity and credit.

Hence the fierce (albeit arcane and polite) dispute between the two sides at the International Monetary Fund’s recent meeting in Lima, Peru. For the literary-minded, it was reminiscent of Jonathan Swift’s Gulliver’s Travels. Gulliver finds himself caught in a war between two tribes, one of which believes that a boiled egg should always be opened at the narrow end, while the other is fervent in its view that a spoon fits better into the bigger, rounded end.

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
