Solving for x gives x =8/15 = 0.533. This means that the executive will win about<br />

53 per cent on salary, and the company will lose about 53 per cent (i.e. win about<br />

47 per cent), which is almost a 50–50 compromise between the low and high figures<br />

they negotiated earlier, only slightly favoring the executive.<br />

This compromise ensures that both the company and the executive will end up<br />

with exactly the same total number of points after the equitability adjustment:<br />

40 + 35(.533) = 80 − 40(.533) = 58.7.<br />

On all other issues, either the company or the executive gets its way completely (and<br />

its winning points), as it should since it valued these issues more than the other side.<br />

Thus, AW is essentially a winner-take-all procedure, except on the one issue on<br />

which the two sides are closest and which, therefore, is the one subject to the equitability<br />

adjustment. On this issue a split will be necessary, which will be easier if<br />

the issue is a quantitative one, like salary, than a more qualitative one like title and<br />

responsibilities. 7<br />

Still, it should be possible to reach a compromise on an issue like title and responsibilities<br />

that reflects the percentages the relative winner and relative loser receive<br />

(53 per cent and 47 per cent in the example). This is certainly easier than trying to<br />

reach a compromise on each and every issue, which is also less efficient than resolving<br />

them all at once according to AW. 8<br />

In the example, each side ends up with, in toto, almost 59 per cent of what it desires,<br />

which will surely foster greater satisfaction than would a 50–50 split down the middle<br />

on each issue. In fact, assuming the two sides are truthful, there is no better split for<br />

both, which makes the AW settlement efficient.<br />

In addition, it is equitable, because each side gets exactly the same amount above<br />

50 per cent, with this figure increasing the greater the differences in the two sides’<br />

valuations of the issues. In effect, AW makes optimal trade-offs byawardingissues<br />

to the side that most values them, except as modified by the equitability adjustment<br />

that ensures that both sides do equally well (in their own subjective terms, which<br />

may not be monetary). On the other hand, if the two sides have unequal claims or<br />

entitlements—as specified, for example, in a contract—AW can be modified to give<br />

each side shares of the total proportional to its specified claims.<br />

Can AW be manipulated to benefit one side? It turns out that exploitation of the<br />

procedure by one side is practically impossible unless that side knows exactly how<br />

the other side will allocate its points. In the absence of such information, attempts at<br />

manipulation can backfire miserably, with the manipulator ending up with less than<br />

the minimum 50 points its honesty guarantees it (Brams and Taylor 1996, 1999b).<br />

While AW offers a compelling resolution to a multi-issue dispute, it requires careful<br />

thought to delineate what the issues being divided are, and tough bargaining to<br />

⁷ AW may require the transfer of more than one issue, but at most one issue must be divided in the<br />

end.<br />

⁸ Aprocedurecalledproportional allocation (PA) awards issues to the players in proportion to the<br />

points they allocate to them. While inefficient, PA is less vulnerable to strategic manipulation than AW,<br />

with which it can be combined (Brams and Taylor 1996, 75–80).
