Regional incentive bidding
A Socratic walk-through of regional incentive bidding — reasoned out one step at a time, not lectured.
The question we started with
THE QUESTION #Why does every region offering a bigger subsidy to win the same factory leave them all poorer than offering none?
A company announces it will build one plant, somewhere in the country. Six regions want it. Each offers tax relief, free land, a training grant. The offers climb. One region wins, hands over a great deal of public money, and holds a ribbon-cutting.
Here is the thing worth sitting with. Suppose no region had offered anything at all. The company would still have built its one plant, somewhere. Somebody would still have won. So what did all that money buy the regions, taken together?
Reasoning it through
REASONING #Let us be careful, because there is a real argument on the other side and we should not knock it down cheaply. A subsidy might genuinely be worth paying if the plant brings a region benefits the company itself does not capture — workers who learn skills they carry elsewhere, suppliers who cluster nearby, a labour market that lifts. Economists call those agglomeration effects, and they are not imaginary. If they are large, a region that pays to attract the plant may come out ahead even after the cheque clears.
But hold that thought and ask a different question: what is the bidding doing, as distinct from the subsidy?
Consider two regions, identical, and one plant. Suppose the plant is worth 100 to whichever region hosts it. Neither bids: one of them gets it — for the reasons that actually decide these things, ports, workforce, motorways — and keeps its 100. Now let one region think privately: if I offer 10, I probably swing it, and 90 is better than a coin flip. Perfectly sound reasoning. But the other region can reason exactly the same way, and will. So the first offers 10, the second offers 20, the first offers 35. Where does it stop?
Ask what stops it, honestly. Each region keeps bidding as long as winning at the current price beats losing. That is true right up until the price approaches the full 100. Whatever the region was going to gain, the bidding hands to the firm — and the plant is still built in exactly one place, most likely the same place it would have gone anyway. Notice the shape: every individual bid was rational, and the collective result is that the regions bought nothing they did not already collectively have.
Do you see what makes this a collective-action problem rather than simple bad judgement? The good in question — the plant — is fixed in supply. The bid is not a payment for creating something; it is a transfer that only changes who gets a thing that already exists. Competitive bidding for a fixed prize does not increase the prize. It relocates the surplus from the bidders to the seller. Each region, acting alone, cannot fix this: unilaterally refusing to bid just means losing while the others still pay. Only a rule binding all of them can.
Two complications keep this honest. First, the winner is not necessarily the region that values the plant most — it may be the one that most overestimated it, or the one whose politicians most needed a ribbon to cut. That is the winner's curse, and it means the winning bid is systematically likelier to be too high. Second, the empirical magnitudes here are genuinely contested: measuring how many jobs a given incentive package actually caused, as opposed to accompanied, is hard, and reasonable economists disagree about it. What is not contested is the structural point about the bidding.
And this is why such rules exist. The European Union's state-aid regime constrains what member states may offer to attract investment, which is precisely an agreement among the bidders not to bid each other up. That is the tell: if bidding were straightforwardly good for the bidders, they would not have negotiated a treaty restraining themselves from it.
The analogy
THE ANALOGY #Picture a charity auction where the item on the block is a bucket of the bidders' own money. Everyone in the room contributed to the bucket; one person will walk out with it. Bid nothing, and someone still takes it home — the bucket does not evaporate. But once bidding starts, each raise is rational for the raiser, and the auctioneer — who contributed nothing — pockets the proceeds. The room ends the evening with the same bucket and less cash than it started with.
the factory, unlike the bucket, is not purely a transfer — it really does produce something, and the firm really can choose to build it in another country or not at all, so the regions are not quite bidding for a prize with a fixed address.
Clarifying the model
THE MODEL #That crack in the analogy is where the serious version of the argument lives, so let us look at it rather than past it. If the alternative is that the plant goes abroad or is never built, then the bidding is no longer purely a transfer among the regions — it may be buying real activity. The strength of the case therefore turns entirely on how mobile the investment truly is, and firms have every incentive to present a decision that was effectively already made as one still hanging in the balance. The information asymmetry is the firm's greatest asset in the negotiation.
A second refinement: none of this says subsidies are always waste. It says the competitive part is. A region that would rationally offer 10 for a plant worth 100 to it has made a defensible investment; a region that offered 95 because five rivals were in the room has not, and the difference between those two numbers went to the firm, not to any region's residents.
The misconception worth correcting gently is that the winning region has been outsmarted by the others. It has not. It has been outsmarted by the structure. Every region played well and the group lost — which is the signature of a collective-action problem, and the reason the remedy is never "bid smarter" but always "agree a limit."
A picture of it
THE PICTURE #How to readstart at the rounded node at the top. Take the diamond and notice that both labelled branches lead to the same action — that is what makes bidding a dominant strategy. Follow the escalation to the two boxes it produces: the plant is sited, and the money leaves, with a back-edge returning to the same question for the next plant. The lower path is the only exit: a binding pact reached before the question is ever asked.
What became clearer
WHAT CLEARED #The loss is not caused by any region bidding badly. It is caused by a fixed prize being auctioned among parties who each gain from raising — so the surplus flows to the firm by the mechanics of the auction, whoever wins. The remedy therefore cannot be found inside the auction; it has to be an agreement standing outside it.
Where to go next
ONWARD #- Clawback clauses and job-guarantee conditions: attempts to make an incentive contingent rather than unconditional.
- Tax competition between countries, and the reasoning behind a global minimum corporate rate.
- Whether agglomeration benefits are large enough to justify subsidies at all, absent any rival bidders.
