We derive a class of utility functions that are equivalent with respect to a well-defined functional form. We study the case of constant relative risk aversion (of some order) to investigate on different equivalence relations in order to determine the, possibly infinite, number of equivalence...

International and national investors are often exposed to real wealth risks, stemming from volatile asset prices and inflation uncertainty, making it difficult to stabilize consumption patterns. However, investors can enter futures markets to hedge against these risks. The paper develops a...

This paper constructs an intertemporal model of the spot and forward markets for foreign exchange and shows that in equilibrium the forward market is unbiased, i.e., the forward rate is equal to the expected spot rate which will prevail in the market next period. This holds true as long as the...

We examine risk taking when the bank's preferences exhibit smooth ambiguity aversion. Ambiguity is modeled by a second-order probability distribution that captures the bank's uncertainty about which of the subjective beliefs govern the financial asset return risk. Ambiguity preferences are...

This paper examines the optimal production and export decisions of an international firm facing exchange rate uncertainty when the firm's preferences exhibit smooth ambiguity aversion. Ambiguity is modeled by a second-order probability distribution that captures the firm's uncertainty about...
