Abstract
Discounting in experimental bargaining games has typically been implemented by shrinking
the pie along the game path. How one should implement real world discounting in a
laboratory setting to imitate real world trade-o s is not obvious, and the procedure chosen
may impact on experimental outcomes. In this study we analyze whether the main results
found in Ochs and Roth (1989) replicate well when using delayed mobile phone payments to
implement discounting.

Experimental Design

Experimental Design
Laboratory experiment: 2X2 design - 2 and 3 period finite alternating bargaining games; With shrinking pie methodology and real time delay methodology.
Observational unit: average behavior in blocks of 10 human subjects. Subjects are kept within blocks and unique subjects are used in all treatments.
Random matching of subjectsFollow up treatments:

We have added an additional 5 treatments:
-2 period alternating bargaining game with .6 discount factors for both players
-2 period alternating bargaining game with .9 discount factors for both players
-2 period alternating bargaining game with 1 week delay discount factors for both players.

Following two treatments are implemented in real time, meaning that disagreement causes the bargaining to be delayed by one week before resuming. Implemented on Mturk.
-2 period alternating bargaining game with 1 week delay discount factors for both players.
-3 period alternating bargaining game with 1 week delay discount factors for both players.
within a block in each new game.
