The Keynesian Cure

At some point, the world economy will begin expanding rapidly again. But what it needs now is a boost to aggregate demand, which requires short-term fiscal expansion and policies that increase the private sector’s effective risk-bearing capacity.

BERKELEY amp#45;amp#45; It is not yet foredoomed that the world economy will undergo a substantial recession in the next three years or so: we might still escape. But governments should play it safe by starting to take more steps now to cushion, soften, and shorten the period of high unemployment and slow or negative growth that now looks very likely.

It is a fact of nature – human nature, at least – that prudent and appropriate policies now will later seem excessive. At some point, the world economy will begin expanding rapidly again. But it would be most imprudent to assume that the turning point is right now, and that things are as bad as they will get.

Perhaps the best way to look at the situation is to recall that three locomotives have driven the world economy over the past 15 years. The first was heavy investment, centered in the United States, owing to the information technology revolution. The second was investment in buildings, once again centered in the US, driven by the housing boom. The third was manufacturing investment elsewhere in the world – predominantly in Asia – as the US became the world economy’s importer of last resort.

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    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.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
