Well, the tax cut provided no immediate incentive to raise wages. It did, however, give companies that benefited from the tax cut a strong political incentive to claim that the tax break was the reason for bonuses or wage hikes they would have given in any case. Why not? They want the tax cut to look good, since it’s good for them. And hyping its benefits is a cheap way to make a de facto campaign contribution to an administration that can do a lot to help companies it likes, say by removing pesky safety or environmental regulations.

In other words, the whole “bonuses thanks to tax cut” story was bogus, and obviously so. Yet much of the media fell for it.

There was also a big element of innumeracy involved. Most people have no idea just how big the U.S. economy is; if you say “company X just hired 1000 workers” or “company Y just gave 5000 workers a $1000 bonus” they imagine that these are big stories, when in reality they’re just noise in an economy where around 5 million workers are hired – and an almost equal number quit or are fired – every month.

The numbers we have so far show that the much-hyped bonuses are trivial – less than $6 billion, or 0.03% of GDP – while stock buybacks have been more than $170 billion. And many of those bonuses would probably have happened anyway, whereas stock buybacks are running far above historical levels.

Furthermore, the surge in stock buybacks suggests that the long run effect of the tax cut on wages will be small. Remember that the chain that should lead to trickle-down begins with lower taxes -> higher investment. If companies use the cuts to buy back stocks, not add to plant and equipment, the wage-growth story doesn’t even get started.

So the real news about the tax cut is that it is – I know you’ll be shocked – mainly a giveaway to corporations. Who could have predicted?
