"leadership meets soft budget"

In this paper, it is shown that real indeterminacy of stationary equilibria generically arises in most matching models with perfectly divisible fiat money. In other words, the real indeterminacy follows from the condition for stationarity of money holdings, and surprisingly it has nothing to do with the other specifications, e.g., the bargaining procedures, of the models. Thus if we assume the divisibility of money in money search models, it becomes quite difficult to make accurate predictions of the effects of some policies.

Soft budgets and local borrowing regulation in a dynamic decentralized leadership model with saving and free mobility

This paper considers a simple dynamic decentralized leadership model with local borrowing and regional productivity enhancing investment. The central government is benevolent but cannot commit. The local governments strategically act while accounting for the ex post motive of the central government. We then investigate inefficiency in the subgame perfect equilibrium. We analyze the effect of central control on local borrowings. It is revealed that the central control is of no use. The model is extended to the case with residential mobility which gives different policy implications
