Signaling Game Experiments", Journal of Applied Econometrics, Vol. 27, 
No. 7, 2012, pp. 1037-1058.

The data are in two files. Both are provided in two formats, Excel (.xlsx)
and plain text (.txt). "high_cost_entrants" contains the data for
experiments with high-cost entrants. "cost_cost_entrants" contains the data
for experiments with low-cost entrants.

The two .xlsx files are zipped in the file lkl-data-xlsx.zip. The two text
files are zipped in the file lkl-data-txt.zip. The text files are ASCII
files in DOS format, so Unix/Linux users should use "unzip -a".

In "high_cost_entrants", there are 4360 observations. In
"low_cost_entrants", there are 9136 observations. Both files have 13
variables (columns). The variables are:

1. Experimental session number.

2. Experimental cycle number.

3. Experimental period number (within a cycle).

4. Team ID. In this paper, we focus on individual decision-making instead of
   team decision-making, so a team has only one Player A and one Player B.

5. Player A (Monopolist) ID.

6. Player B (Entrant) ID.

7. Player A's type, which is 1 if A is a high-cost type and 2 if A is a
   low-cost type.

8. Player B's choice, which is 1 if B chooses OUT and 2 if B chooses IN.

9. Player A's output (or price) choice.

10. Player A's payoff in the current period.

11. Player B's payoff in the current period.

12. Player A's gender, which is 0 if male, 1 if female, and 2 if unknown.

13. A indicator variable for experimental treatment given by
    100*exper+10*ctx+pitts, where exper is 1 if the session recruits
    experienced subjects and 0 otherwise, ctx is 1 if the session uses
    natural language (meaningful context) for instructions and 0 otherwise,
    and pitts is 3 if the session was conducted at the University of
    Pittsburgh and 0 if it was conducted at the Ohio State University.
