          <dc:description>This research project analyzes the effect of a change in the reference point and the endogenous decision to reveal the reference point on the real effort provided in a real effort laboratory experiment. Absolute differences in the performance in a repeated math task are endogenously or exogenously revealed or not revealed at all participants in a group, before participants redo the math task again.

This experiment ran in the experimental software "zTree"

The dataset contains the following folders:

- "Instruktionen": The instructions that where handed out to the experiments' participants, regardless of the treatment that was run.
- "zTree": The zTree source code that was used or running the individual sessions.
- "Daten": The experimental data of thirteen (13) sessions, held between May 30th and June 21st in 2016.</dc:description>

          <dc:description>This research project analyzes monetary intertemporal choices when trading-off individual and income that is donated. Donations have the form of warm glow of giving, while income decisions are elicited in a convex time budget constraint. Treatment conditions vary the urgency of the donation. 

This experiment ran in the experimental software "oTree"

The dataset contains the following folders:


	 "Ablaufplan": The instructions for the experimenter
	 "Instruktionen": The instructions that where handed out to the experiments' participants for three different treatments T1, T2 and T3
	 "oTree": The oTree source code that was used for running the individual sessions.
	 "Daten": The experimental data of four (4) sessions, held between February 3rd and February 12th in 2020.
	 "Spende": Receipts of the donations that were made to "SCM (Christoffel Blindenmission)"
