When talking about stock markets, there are three rules you have to remember. First, the stock market is not the economy. Second, the stock market is not the economy. Third, the stock market is not the economy.
So the market plunge of the past few days might mean nothing at all.
On one side, don’t assume that there was a good reason for the slide (although the fact that the Dow fell 666 points on Friday hints either at satanic forces or at some mystical link with the Kushner family’s bum investment at 666 Fifth Ave). When stocks crashed in 1987, economist Robert Shiller carried out a real-time survey of investor motivations; it turned out that the crash was essentially a pure self-fulfilling panic. People weren’t selling because some news item caused them to revise their views about stock values; they sold because they saw that other people were selling.

And on the other side, don’t assume that the stock price decline tells us much about the economic future, either. The great economist Paul Samuelson famously quipped that the stock market had predicted nine of the past five recessions. That 1987 crash, for example, was followed not by a recession, but by solid growth.
Still, market turmoil should make us take a hard look at the economy’s prospects. And what the data say, I’d argue, is that at the very least America is heading for a downshift in its growth rate; the available evidence suggests that growth over the next decade will be something like 1.5 percent a year, not the 3 percent Donald Trump and his minions keep promising.
There are also suggestions in the data that risky assets in general – stocks, but also long-term bonds and real estate – may be overpriced. Leaving bitcoin madness aside, we’re not talking dot-coms in 2000 or houses in 2006. But standard indicators are well above historically normal levels, and a reversion toward those norms could be painful.
About that plummet: If there was any news item behind it, it was Friday’s employment report, which showed a significant although not huge rise in wages. Now, rising wages are a good thing. In fact, the failure of wages to rise much until now has been a deeply frustrating deficiency in the otherwise impressively durable economic recovery that began early in the Obama administration.
But we’re now seeing fairly strong evidence that the U.S. economy is nearing full employment. The low measured unemployment rate is only part of the story. There’s also the growing willingness of workers to quit their jobs, something they don’t do unless they’re confident of finding new employment. And now wages are finally rising, suggesting that workers are gaining bargaining power, too.
Again, this is all good news. But it does mean that future U.S. growth can’t come from putting the unemployed back to work. It has to come either from growth in the pool of potential workers or from rising productivity, that is, more output per worker.
Yet with baby boomers retiring, growth in the U.S. working-age population, especially in prime working years, has slowed to a crawl, while productivity growth has been disappointing. Together, these factors suggest an economy likely to grow only half as fast as Trump promises.
Did the markets believe Trump? At the very least, they’ve been acting as if the U.S. economy still had lots of room to run; throwing cold water on that belief should mean both higher interest rates and lower stock prices, which is what we’re seeing.
But should we be worried about something worse than a mere downshift in growth?
Well, asset prices do look high: A widely used gauge of stock valuations puts them at a 15-year high, while a conceptually similar measure says that housing prices have retraced a bit less than half the rise that culminated in the great housing bust.
Individually, these numbers aren’t that alarming: Stocks, as I said, don’t look nearly as overvalued as they did in 2000, housing not nearly as overvalued as it was in 2006. On the other hand, this time both markets look overvalued at the same time, at least raising the possibility of a double-bubble burst like the one that hit Japan at the end of the 1980s.
And if asset prices take a hit, we might expect consumers – who have been spending heavily and saving very little – to pull back.
Still, all of this would be manageable if key policymakers could be counted on to act effectively. Which is where I get worried.
It’s surely not a good thing that Trump got rid of one of the most distinguished Federal Reserve chairs in history just before markets started to flash some warning signs. Jerome Powell, Janet Yellen’s replacement, seems like a reasonable guy. But we have no idea how well he would handle a crisis if one developed.
Meanwhile, the current secretary of the Treasury – who declared of Davos, “I don’t think it’s a hangout for globalists” – may be the least distinguished, least informed individual ever to hold that position.
So are we heading for trouble? Too soon to tell. But if we are, rest assured that we’ll have the worst possible people on the case.
