Experiment
This is an experiment in
3 parts
.
Rounds
This part of the experiment consists of
5 rounds
.
Players
This is an experiment for
2 players
, called player
1
and player
2
. You will be told which player you are at the start of the first round. You will not change roles during this part of the experiment: in other words, if you start off as player 1 in the first round, then you will remain player 1 in subsequent rounds.
Objects
There are
4 objects
, labelled
A
,
B
,
C
and
D
. These objects are worth
different
amounts of money to each player.
For example, object A might be the most valuable object to player 1 but the least valuable object to player 2.
The valuations are
common knowledge
, i.e. the players know the value of the objects to the
other
players as well as the value to themselves.
Choices
The 2 players take turns to choose an object.
First
to choose is player
1
, who chooses one of the 4 objects. The chosen object becomes player 1's property and cannot be chosen a second time by anyone.
Second
to choose is player
2
, who chooses one of the 3 remaining objects.
Finally
, player
2
chooses one of the 2 remaining objects, leaving just 1 object un-chosen, which becomes player
1
's property by default.
Play Order
As described above, the
play order
, which is the order in which the players choose an object, is
1221
. The play order is
the same
for each round of this part of the experiment.
Multiple Random Matchings
You will be
re-matched
at the start of each round with another person selected
at random
from the other participants. There will be a
new
random matching each round, so you may
or may not
be matched with the same person in two consecutive rounds. The matchings are random, so you are no more likely to be matched with one participant than with another.
