The operation of the coinsurance arrangement is examined under different loan contracts. It shows that, if the IMF ´ s objective is to safeguard its resources and be concerned about the welfare of the borrower, an ex ante loan contract is more likely to create the right incentives than an ex post loan contract. Such contracts highlight the need for precommitment to contend with the Samaritan ´ s dilemma and time inconsistency, and state-contingent repayment schemes to deal with King Lear ´ s dilemma.   Paper submitted to the special issue " Recent Developments in International Money and Finance " edited by Ronald MacDonald http://www.economics-ejournal.org/economics/discussionpapers/2007-26 JEL D82 JEL F02 JEL F33 JEL G22
