Abstract
In the reality, most bribery happen with solicitation. However, most papers analyzing bribery do not contain solicitation. We develop a model to estimate the effect of solicitation in a collusive bribery game. Our experiment will be published on Prolific.

Experimental Design

Experimental Design
Subjects will be randomly assigned to 2 roles: Government Staff or Citizen. And they will also be randomly assigned into four treatment groups with different level of solicitation. Specifically, different level of solicitation means Government Staff can choose to send a certain fixed sentence.

Citizen have to play a game then report the result to government staff. Government staff then have to report the result to server, but he/she have the right to manipulate the result. Citizen can choose to send some tokens to government staff. And government staff has to choose whether to accept the result or not and whether to manipulate the result or not.
Experimental Design Details
Those sentence are:
1. No sentence. (Control group)
2. Hi, nice to meet you! (Irrelevent Message)
3. I want some tokens as a gift. (Ambiguous Message)
4. I want X tokens as a gift. (Government Staff can choose X) (Clear Message)
Randomization Method
Computer choose a random number to assign their role and treatment group.
Randomization Unit
Individual.
Was the treatment clustered?
No
