Discrete-Time Valuation of American Options with Stochastic Interest Rates

Review of Financial Studies 1995 8(1), 193-234
We develop an arbitrage-free discrete time model to price American-style claims for which domestic term structure risk, foreign term structure risk, and currency risk are important. This model combines a discrete version of the Heath, Jarrow, and Morton (1992) term structure model with the binomial model of Cox, Ross, and Rubinstein (1979). It converges (weakly) to the continuous time models in Amin and Jarrow (1991, 1992). The general model is “path dependent” and can be implemented with arbitrary volatility functions to value claims with maturity up to five years. The model is illustrated with applications to long-dated American currency warrants and a cross-rate swap from the quanto class.

Closed-end Country Funds and U.S. Market Sentiment

Review of Financial Studies 1995 8(3), 879-918
[Closed-end country funds can trade at large premiums and discounts from their foreign asset values (NAVs). Investigating this anomaly, we find that individual fund premiums move together, primarily because of the comovement of their stock prices with the U.S. market. Moreover, an index of country fund premiums differentiates size-ranked U.S. portfolio returns and forecasts country fund stock returns. These findings suggest that international equity prices are affected by local risk. In particular, we show that country fund premium movements reflect a U.S.-specific risk, which may be interpreted as U.S. market sentiment.]
