A major empirical interest is whether a permanent change in economic fundamentals produces a growth effect. However, a direct time series analysis of this hypothesis may not always be feasible due to a lack of such events. This paper explains why a test regarding the long run effect of a...

This paper concentrates upon the short-term changes in the exchange rate that might be considered as 'clouding' more fundamental changes. We focus on week to week changes in nominal bilateral exchange rates. The main concern of this paper is an attempt to identify the sources of exchange rate...

In strictly competitive games, equilibrium mixed strategies are invariant to changes in the ultimate prizes. Dixit & Skeath (1999) argue that this seems counter-intuitive. We show that this invariance is robust to dropping the independence axiom, but is removed if we drop the reduction axiom.

Suppose, following Kreps & Porteus (1978), that an agent values information not only to make contingent plans but also for itself; that is, intrinsically. What, then, is the relationship between an agent's attitude towards information and her attitude towards risk? If an agent always prefers more...

In a carrot game for a player, that player must help his opponent in order to get a desired response. In a stick game for a player, that player must hurt his opponent to get a desired response. We show that most all smooth monotonic two player games can be classified as: carrot for both, carrot...
