Private transfers with incomplete information: A contribution to the "altruism-exchange motivation for transfers" debate

We examine the role of altruism in determining optimal transfers from a principal (a mother) to selfish agents (her children) in return for attention services. Transfer-attention contracts are studied in a setting in which informational asymmetries arise from the inability of a parent to determine the extent of her children's selfishness. We find a predominating exchange motive for transfers in the symmetric informational regime we study. However, both altruism and exchange are important motives under asymmetric information. We show that altruism facilitates transfer-attention exchange arrangements with certain trade partners under incomplete information, but diminishes trade with others.
