Think about an public sale that takes place between three bidders. The merchandise in query? An envelope crammed with cash. All three bidders make use of groups of analysts that try to establish how a lot cash is within the envelope, based mostly on quite a lot of proof that isn’t necessary for this analogy. Every bidder thus arrives at an estimate of the truthful worth of the envelope. Then they place a single sealed bid. The very best bidder out of the three will get the envelope.
What bidding technique would you use? Right here’s a foul one: Simply bid what your crew of analysts calculates because the anticipated worth of what’s within the envelope. The explanation that is dangerous is named the winner’s curse. If every bidder comes up with an estimate of truthful worth and bids that quantity, the winner would be the one with the best estimate of truthful worth. In different phrases, you’ll solely win in case your estimation of the envelope’s worth is increased than everybody else’s, and because you’re all the time paying precisely what you’re hoping to achieve, you’ll are inclined to lose in the long term.
Permitting for lots of approximation, this example describes free company in main league baseball. Each free agent has an unknowable quantity of anticipated future manufacturing. Groups make use of armies of analysts who try to estimate that manufacturing. Then, armed with that data, they make contract gives to that free agent, in competitors with different groups.
As I mentioned, there’s a ton of approximation and simplification happening right here. Gamers aren’t envelopes crammed with cash. Staff context issues. Gamers don’t have to just accept the best bid. Tax regimes aren’t equal, and non-monetary incentives matter, too. Contracts are complicated, and there’s no requirement that they be the identical variety of years, have the identical variety of choices, no commerce clauses, or something of the type. There’s no agreed-upon common worth system; totally different gamers current totally different worth to totally different groups.
However that doesn’t imply the abstracted case has no use. As we method the commerce deadline, I feel there’s one clear one: dispelling the parable that groups refuse to surrender a lot to commerce for a participant who simply signed an enormous free agent deal — in spite of everything, in the event that they valued them sufficient for a blockbuster, they might have simply supplied a much bigger contract, proper? That’s a fantastic soundbite, so that you hear it on a regular basis, nevertheless it doesn’t jive with established financial concept.
The fashion of contract negotiation the place a number of bidders submit bids and a single vendor chooses one among them could be stylized as an public sale. “Public sale” may sound like a bizarre approach to describe it, however when you cease to consider it, it makes good sense. It’s a manner for a number of bidders to make use of their willingness to pay to distinguish themselves to a vendor.
The basic public sale you consider is an English public sale. There’s an auctioneer, and a few outdated folks with monocles and paddles. The value retains going up unit by unit; when you worth one thing greater than the present bid value, it’s optimum to bid extra for it. In concept, the value will proceed to go up till the bidder with the second-highest valuation of the merchandise being auctioned reaches their high valuation and drops out of the bidding. The bidder who has the best valuation then wins the public sale, paying solely sufficient to outbid the valuation held by the second-highest bidder.
A fast instance: let’s say that we’re bidding for a Cal Ripken Jr. baseball card. I feel it’s value $250, you assume it’s value $200, and Meg Rowley thinks it’s value $600. Beneath $200 {dollars}, everybody’s bidding. You drop out at $200. I drop out at $250, leaving Meg the successful bidder at both $250 or $251, relying on who bid $250 first. The bidder with the best valuation gained, and the value they paid is the valuation held by the bidder with the second-highest valuation. (A nit-picky tutorial apart: For those who assume that bids could be made in any increment, the successful bidder pays a fraction of a cent greater than the second-highest bidder’s valuation. That’s why it’s expressed because the second-highest valuation; a bid of $250.00000001 is shut sufficient to $250 that there’s no level in distinguishing.)
It doesn’t matter whether or not Meg thought the cardboard was value $300, $650, or $10,000. The second-highest bidder’s valuation units the value. That’s not how free company works. If Staff A gives Participant X a $100 million contract, Staff B can’t eavesdrop on the telephone line and say “$101 million” just for Staff A to counter with “$102 million” and so forth. Comparatively few gives are made. Typically talking, they’re made with out actual data of what the opposite events are doing. When Staff A gives that $100 million contract, they don’t have any manner of figuring out whether or not different groups are in the identical ballpark as them. Possibly the next-highest supply is $80 million. Possibly there’s already a $130 million supply on the desk.
Earlier than I get into the meat of my argument, it’s value making one factor clear: Cash isn’t a proxy for anybody’s worth. There’s no manner round modeling it that manner in these easy abstractions, however they’re simply that: abstractions. They aren’t an ideal mirror for the true world. To give you a mannequin, you need to have some form of single-unit measure of worth, and I’m utilizing {dollars} for the sake of simplicity. That’s not actual life. The optimum quantity to supply somebody in trade for his or her companies taking part in baseball doesn’t say something about their “value”; it’s simply financial (and free agent contract) shorthand.
Let’s return to free company. The easiest way to explain these negotiations, for the needs of defining a generic sport, is a first-price sealed-bid public sale. On this fashion of public sale, bidders submit a single sealed bid with out data of different bids. The vendor then selects the best value and sells the great to that bidder for that value. It’s not fairly an ideal match – negotiation occurs after bids have been submitted, and groups continuously submit a number of gives over time – nevertheless it’s a very good first-order approximation. And the established technique is decidedly not “bid what you assume the great being auctioned is value.”
Let’s speak about why. Assume our three-bidder envelope state of affairs from above. Additional assume that the worth of the envelope is $100, and that the three groups bidding for the envelope have analysts who independently calculate their very own expectation of that worth. These calculations are randomly distributed round $100, with a normal deviation of 15 proportion factors.
Within the case the place every crew bids 100% of their calculated worth, they every win a 3rd of the time (clearly). On common, the sale value is 112.7% of $100 – oof! Think about being a kind of groups of analysts and suggesting this plan to your boss. “We’re going to bid in an public sale. We’ll win a 3rd of the time. On common, we’ll be overpaying by 12.7%. Oh, and we’ll solely pay lower than the envelope is value 12.5% of the time that we win.” That is an clearly abysmal plan.
The clear drawback right here is that you simply shouldn’t bid an quantity such that you simply’ll by no means be enthusiastic about successful. For those who all the time pay 100% of what you assume a factor is value, the one manner you find yourself successful is that if a) you undervalue the merchandise in query and b) each of your rivals on this sport do as effectively, and by greater than you probably did. That doesn’t occur fairly often. A greater technique is to bid an quantity decrease than you assume the merchandise is value, however nonetheless near the worth, as a way to nonetheless win some proportion of the time with out paying vastly greater than its worth.
To do a bit higher than broad generalizations, I wrote a Python script that simulates this public sale. That’s the place I obtained the 112.7% quantity, in addition to the 12.5%. That’s with every of the three groups bidding 100% of their calculated worth within the public sale. To determine different methods, I can simply change the bid.
For instance, if Staff A bids 88.8% of its estimate whereas the opposite two groups bid 100% of theirs, issues change meaningfully. Now the outcomes appear to be this:
Implied Values, Staff A 88.8%
Staff
Bidding Technique
Hit Fee
Common Worth Paid

A
88.8%
14.0%
104.6%
32.7%
B

43.0%
110.6%
17.9%
C
100%
43.0%
110.6%
17.9%
A fast explainer on the columns: bidding technique refers to what proportion of their calculated truthful worth a given crew bids within the public sale. Hit charge is how continuously a given crew wins. Common value paid is what proportion of true worth (100%) every crew pays, on common, throughout all its successful bids. Discount proportion is the share of successful bids that present constructive worth, i.e. the place the successful bid is lower than 100%.
Now, Staff A’s technique seems meaningfully higher to me than their two rivals. They’re successful auctions much less continuously, positive, however successful wasn’t so nice when it was nearly by no means a very good deal. If this can be a repeated sport (many auctions over time), like free company, you’d count on Staff B and Staff C to rein of their methods. What in the event that they, too, began bidding 88.8% of their estimate in an try to rein in prices?
Implied Values, All Groups 88.8%

100.1%
51.2%
C
88.8%
33.3%

51.2%
That 88.8% determine wasn’t chosen at random; it’s the ratio that, on this instance, produces an anticipated price of roughly 100% for every bidder if all of them comply with the identical rule. Roughly 50% of the time, the value paid finally ends up being a discount, which follows logically. If you wish to counter the winner’s curse, you need to bid lower than your anticipated worth, and that holds for everybody concerned within the bidding.
This isn’t what economists name a steady equilibrium. Now that Staff A’s rivals are bidding much less aggressively, Staff A can bid even much less aggressively than the rivals and seize some anticipated income, at the price of successful the public sale much less continuously:
Implied Values, Staff A Conservative

99.3%
54.5%
C
88.8%
37.4%

54.5%
Now, on common, is that this deal value it for Staff A? If all they care about is maximizing extra worth, positive. In the event that they’re concentrating on some minimal quantity of worth added – think about this previous yr’s Giants, who had cash to spend and wished so as to add some gifted gamers with it – being extra passive than breakeven is perhaps a foul technique, as a result of it has an opportunity of leaving you with nothing.
Apparently, Staff A bidding much less aggressively makes Staff B and Staff C’s outcomes look higher, even with a static bidding technique of 88.8%. As Staff A will get even much less aggressive, issues proceed to look rosier:
Implied Values, Staff A Opportunistic

Possibly that’s a Tampa Bay fashion of technique. Are available low, figuring out you’ll normally miss. While you do hit, you’re in all probability clearing a very good deal. Alternatively, if one of many bidders will get extraordinarily conservative, perhaps it is sensible for an additional bidder to get aggressive to take benefit:
Implied Values, Staff B Aggressive

52.9%
100.0%
51.7%
C
88.8%
40.0%
56.7%
57.7%
Staff A’s timid bidding signifies that the winner’s curse is lessened. Loads of occasions, Staff B will win not as a result of it has the best valuation, however as a result of Staff A simply isn’t competing sufficient. That opens room to get increasingly aggressive in bidding relative to modeled worth. Now Staff B is successful the public sale a full half the time with out dropping cash on common.
You may mess around with this fashion of study endlessly. Staff C may even have room to get much less aggressive themselves at this level, since they’re typically going to beat Staff A anyway. In the event that they again off, they will win a ton of auctions whereas nonetheless getting significant constructive worth on those they win:

If groups must act with out figuring out their rivals’ technique, there’s no strong-form equilibrium to be discovered. Sport theorists have calculated what’s referred to as a Bayesian-Nash equilibrium for one type of this public sale when public sale valuations are drawn from a steady uniform distribution, however that’s not what we’re coping with right here. In any case, the proper habits for a given crew is dependent upon the habits of others, however in each case, the optimum bid is lower than 100% of calculated worth.
This is sensible intuitively. Think about a GM successful the public sale to signal an influence participant. If the “each crew bids as much as its indifference level” crowd are right, that GM’s response ought to be simply that: indifference. “I like my crew the identical as I appreciated it earlier than signing Bryce Harper as a result of I made a bid of precisely what I’m keen to pay to the purpose the place his deal has no surplus worth.” That appears dumb on its face. Groups don’t bid totally free brokers as a result of, if their bid is accepted, they’ll be detached. They do it as a result of they need to add that participant at that value. They’d desire to win versus lose the bidding. In any other case they wouldn’t bid that a lot!
If groups are performing as economically rational actors, they need to rue lacking out on free brokers pretty usually. To depart your self room to come back out forward, you need to generally miss on bargains. Groups are not any fools. They perceive this idea. I’m keen to wager that, some vital fraction of the time, groups see the phrases for a free agent who simply signed and assume “Ooh, we missed on that one.” While you’re bidding at nighttime, that must be the case if you wish to choose a successful technique in the long term.
For quite a lot of causes, this abstracted instance isn’t an ideal reflection of free company. I picked three groups moderately than 4 or 5 arbitrarily. I don’t have any specific reasoning behind my 15% commonplace deviation choice; the true variation in projections is probably going smaller than that, although I don’t have entry to crew valuation fashions to say that with any certainty. Reduce the variance time period from 15% to 7.5%, and the bidding technique that produces no extra worth strikes up from 88.8% for every crew to 94.5%. There’s nothing particular about these numbers; I’m simply utilizing them to point out how the mathematics works moderately than saying they precisely signify actuality.
The very idea that each crew has a constant valuation framework might be incorrect; all of them little doubt have some model of it, however gamers output hits and runs and strikeouts and walks, not {dollars}. It’s all very oblique, and totally different groups in all probability deal with that course of in extraordinarily totally different fashions. Do you have to account for advertising and marketing worth? Blocking a prospect? A crew’s place on the win curve?
A marquee participant modifications the equation much more. Certain, in concept you’re taking part in a repeated sport, and making good choices in the long term provides up. However every free agent is exclusive. You don’t get to bid on Harper 15 occasions and have a look at how you probably did in mixture; there’s solely one among him and he’s not a free agent yearly. That may trigger groups to diverge from “optimum” long-run habits; gamers aren’t fungible, and there actually is perhaps no changing the man you miss. What are you going to do, commerce for him?
I additionally don’t assume that the calculations are completed on the phrases I’m describing right here. Groups nearly actually don’t calculate up some grid of anticipated manufacturing worth and low cost from there. I assume it occurs extra organically: A GM goes to their crew of contract specialists and says one thing alongside the traces of “give you a contract supply for Participant X that may make us completely happy if we signal him.” Kind of wiggle room may get added based mostly on how badly the crew wants that individual participant, whether or not the proprietor is a fan, or no matter different components you possibly can consider. Sport concept by no means must explicitly come into the dialogue.
I’m not claiming that I’ve solved the equation. I don’t assume I ever will, in reality. In all probability, nobody can resolve this drawback completely. However I feel the overall conclusion is inescapable. Groups completely count on to get a constructive profit when a free agent accepts their contract supply. A significant fraction of free brokers signal offers that pay them much less per contribution than some arbitrary truthful worth, normalized throughout all free brokers, would recommend. Mathematically, it simply must be that manner.
What do you have to take away from this text? It’s mainly this: cease pondering {that a} free agent contract is an ideal reflection of precisely what the league, as a complete, thinks a given participant’s contributions are value. Nothing about the way in which free company works means that conclusion – it’s a logical fallacy. It feels like every public sale ought to discover the truthful worth of the factor being auctioned, however that’s not the way it works. Auctions discover the public sale clearing value, which typically contains some anticipated revenue for the client.
Sufficient competitors can erode that anticipated revenue to roughly zero, however even then, an expectation of zero implies that about half of the time, the client shall be getting a discount. Different groups know that, and whereas “what did this man get in free company” is a helpful information level for understanding a participant’s worth in commerce, it’s undoubtedly not the tip of the argument. If you wish to work out what groups would give as much as get a participant, don’t simply lean on precedent. Begin from first ideas and determine it out. The shortcut of “oh they have been a free agent so I can assume they’re being paid completely effectively” simply doesn’t work.
