A study of nearly 80,000 European firms finds that when corporate tax rates rise, high-productivity domestic companies get more productive while low-productivity ones slide — the tax acts as a filter.
Recessions are not all bad. Weak companies fail, strong ones get room to grow — what economists call Schumpeterian creative destruction. For the past two decades, though, governments have kept bailing firms out, so large-scale destruction has barely happened.
A tax hike as a sieve
A researcher named Nguyen looked at a smaller version of that filter: raising corporate tax rates. The logic is simple — if the taxman takes more, you have less to spend, so you have to squeeze more output out of less.
He went through the books of almost 80,000 European companies and found that yes, after a tax hike firms do raise their productivity. But not all of them.
Who gets stronger, who falls behind
He sorted the firms by how productive they were before the tax went up. The capable ones sit on the left, the struggling ones on the right. After the hike, the left side keeps climbing, while the right side, starved of internal cash, slides down.
In other words, the tax itself picks winners: it pushes resources toward the efficient firms and drives the inefficient ones toward the exit.
The multinational back door
The pattern does not hold for multinationals. Faced with a higher tax bill, they do not tighten up and get efficient — they just move production to another country.
So the next time a boss complains about high taxes, tell him only companies weaker than their rivals need to worry. For the fitter ones, a tax hike just makes them grow faster.
Why it matters
The familiar claim that higher taxes choke the economy turns out not to be uniform: it squeezes out the least efficient firms while pushing the most efficient ones up a notch. What matters is not the tax itself but which end of the productivity ranking you sit on.
