From Greg Ip: In Davos, Nobody Knows Anything, and That’s the Problem

The raison d’être of Davos is intelligence gathering. Hedge funds go to chat up CEOs, CEOs go to chat up politicians, politicians go to chat up donors, and journalists go to chat up everyone.

This year, all that chatting is yielding distressingly little intelligence, and that helps to explain why the mood here, and indeed over the world economy, seems so dark.

Here are the questions people here most want answered: How will Brexit be resolved? No one knows, certainly not British parliamentarians or cabinet ministers. When will the federal government shutdown ends? Nobody knows. Will the U.S. and China reach a deal to avoid all-out trade war by March 2? Nobody knows. This isn’t because no one from the Trump administration is here; if they were, they wouldn’t know, either (or so the people here who have dealt with Trump have concluded).

In the economy uncertainty is, of course, a constant. Businesses, markets and investors are used to working with probabilities rather than certainties, whether it’s the outlook for profits or interest rates. But with today’s problems you can’t even assign probabilities. Since Mr. Trump himself does not seem to know what he wants out of the China trade talks, how can you judge the odds and provisions of a deal?

How do you assign a probability to Mr. Trump or Democrats breaking a promise to their bases, as would be necessary to end the partial federal shutdown? Shutdowns used to treated as localized natural disasters, Harvard economist Ken Rogoff noted on a panel moderated by Journal editor Matt Murray: painful for those involved but without national repercussions. This shutdown, he said, is like one local disaster after another, each worse than the one before. In such a situation, “We don’t know what happens.”

As for Brexit, French finance minister Bruno Le Maire, asked about reopening the European Union’s deal with Britain, shrugged: “It’s up to the British people and British politicians to decide what they want.”

“Nobody knows anything,” screenwriter William Goldman once said of making hit movies. Too bad he died last year; he could have taught Davos a thing or two.
