The experiment will involve male participants in the age group of 18-35 years, selected from the sampled villages of Patna-Rural district of Bihar, India. Participants or subjects will be selected from Upper Caste and Scheduled Caste categories. Each session will consist of three to four groups of four individuals playing a simple public good game: every player will be given a fixed amount of money/goods and will be asked to contribute towards a common pool. The treatment variations are along two basic dimensions: the composition of the group and the nature of the good in terms of which the endowment and pay-offs are defined. We now discuss the two differentiating criteria in more details.
In homogenous sessions, all four subjects participating in the session will be from the same caste group, either Upper Caste (UC, henceforth) or Scheduled Caste (SC, henceforth). In heterogeneous sessions, two of the players will belong to the SC category, while the remaining two will be from UC category. The caste composition in each group will be common knowledge, though the game itself will be anonymously played.
A standard money based public good game cannot possibly invoke associative distaste since the act of sharing itself is absent. As a result, we introduce a variant of the public good game where subjects play with biriyani (a delightful self-contained meal with substantial aspiration value in India) instead of money. a substantial aspiration value in India. Thus, in our experiment there will be three kinds of goods in terms of which sessions will be differentiated.
