  We study a communication game between an informed sender and an uninformed
receiver with repeated interactions and voluntary transfers. Transfers motivate
the receiver's decision-making and signal the sender's information. Although
full separation can always be supported in equilibrium, partial or complete
pooling is optimal if the receiver's decision-making is highly responsive to
information. In this case, the receiver's decision-making is disciplined by
pooling extreme states where she is most tempted to defect.
