We analyze reputation in a game between a large player and a continuum of long-lived small players in which state variables affect players' payoffs. The large player's type is private information. We give conditions under which in every Nash equilibrium a very patient large player will get almost the largest payoff consistent with the small players choosing a best response in a large finite truncation of the game. While our results apply to the time inconsistency problem of optimal government policy, we show that for the durable goods monopoly reputation may fail to improve the monopolist's payoff ; Marco Celentani gratefully acknowledges the financial support of DGICYT, Grant PB92-0245 and of HCM Programme, grants ERBCHBICT 940975 and CHRXCT 940458.

We consider a two-country model in which international risk-sharing is beneficial. Even though complete contingent markets exist to trade private wealth, the fact that fiscal policy voting decisions have an impact on contingent wealth prices implies that government spending will be inflated in good states and deflated in bad ones, with the following general implications: (i) Prices of contingent wealth are distorted; (ii) Volatility of public spending increases; (iii) Incomplete insurance arises. An example shows that apart from the increase in the volatility of public spending, it is also possible that average spending increases in both countries. These distortions are shown to be stronger the more similar the two countries are in ex ante terms . We compare the decentralized system with a fiscal union contrasting eqUilibrium properties in terms of government spending and allocation of risk.

International business transactions pose the problem of deterring bribing of public officials by foreign firms. We first analyse a convention styled after the OECD's 'Convention on Combating Bribery of Foreign Public Officials in International Business Transactions', which requires signatory countries to proceed against firms that have bribed public officials of any foreign country. We then study the case in which the convention requires signatory countries to proceed against firms that have bribed public officials of signatory countries only. We argue that the second type of convention is more likely to ensure the enforcement of penalties.
