Incentives and anonymity principle : crowding out toward users

In our model, an agent produces an outcome by a costly effort and then distributes it among heterogeneous users. The agents̕ payoff is the weighted sum of the users ̕shares and the coefficient reflecting their heterogeneity. When the agent neglects users ̕heterogeneity the game leads to an anonymous allocation. Otherwise, the equilibrium distribution is non- egalitarian but more efficient. Low performing agents reduce inequality among users by delivering an egalitarian service, while intermediate or high performing agents tend to prefer (but not always) delivering an unequal service, thereby breaking the anonymity principle. Incentives do matter regarding the crowding effect toward users.
