Summary

You'll be in groups of 10 and play 10 rounds. You'll be randomly matched with someone each round. Each round has 100 objects A and 100 objects B. You'll bargain to split them. You have an outside option for A, randomly chosen between 0 and 100. For B, your outside option is zero, but you have a multiplier 0.7, 0.8, 0.9, 1, 1.1, 1.2, or 1.3. The objects are interdependent, and you cannot agree on split of objects B without agreeing on split of objects A.

You'll make offers for both types of objects {A,B} together. An offer shows how many objects you offer to the opponent. Opponent’s offer shows how many objects are offered to you.

You can accept or reject active offers. If accepted, the objects are distributed.

Bargaining ends an offer is accepted, time runs out, or one of the players decides to end it.

Earnings are calculated based on the number of objects you agree on

If the number of objects A is greater or equal to the outside option:

Earnings (in ECU)= Number of objects A + Multiplier x Number of objects B

If the number of objects A is smaller than the outside option:

Earnings = 0 ECU

One round will be randomly selected for payment at the end. Each ECU earned equals 0.03 pounds.
