Should you hold your price, or cut first?

Your best price depends on what your rival does, and theirs depends on you. That is a game, not a forecast, and this template solves it: dominant strategies, the equilibrium you will actually land on, and exactly what a truce is worth to each side.

Operations Intermediate Game Theory Pro engine

After you install, this is the model to open.

Price War: Hold or Cut?

  1. In your spreadsheet, click the Sortia icon in the strip of icons down the right-hand edge. No strip? Click the arrow at the bottom-right to open it. You can also use Extensions, then Sortia, then Open Sortia.
  2. Click Start from a template and put that name in the search box.
  3. Pick the card with that name and click Load this template. It arrives on a new tab with real numbers already in it.

This one runs on a Pro engine, and every free install includes five full-quality runs on your own numbers, shared across all five Pro engines rather than five for each. After that, Pro is $199/year.

The answer

What rational play looks like:

Equilibrium
Both cut $4M each
The truce
Both hold $8M each
Temptation
$2M per side
Verdict
Prisoner's dilemma

Cutting is each side's dominant strategy, so the game settles at both cut, $4M each, even though both holding pays $8M each. The report prices the temptation to break a truce at $2M a side: that is the number any agreement, repetition, or reputation has to outweigh. Edit the four cells to match your market and see whether the dilemma survives.

The model

A 2x2 payoff grid in $M of margin. Each cell holds both payoffs, yours then theirs, for one combination of moves.

Both holdYou $8M · Rival $8M
You hold, they cutYou $2M · Rival $10M
You cut, they holdYou $10M · Rival $2M
Both cutYou $4M · Rival $4M

Once it is in your sheet

  1. The model arrives with real numbers in it and runs as it stands, so you can press the button first and understand it second.
  2. Change the numbers to yours. The sheet marks which cells are inputs and which hold formulas, and most labels carry a note explaining the row.
  3. Press the run button at the bottom of the panel. It is labeled for the tool you are in, and the result lands on its own tab, with a written reading of it beside the figures.
