THE PRINCIPAL PURPOSE of this dissertation was to determine the interspatial and intertemporal price effects that devaluation transmits between two international competitive markets transacting a homogeneous commodity. The thesis examines and explains international price-spread movements between futures markets in the United States and Great Britain during Sterling crisis periods. Typically, most of the work that has been done in the areas of international finance and economics has addressed itself solely to the static case in which goods or assets are priced and transacted for immediate delivery. The approach of this thesis differs considerably from previous studies in that the element of time is introduced into the analysis of a two-country, one asset model. Another interesting aspect of this study is that commodity futures are metamorphic and can take the form of either an investor's or speculator's asset, or a producer's or consumer's good. The thesis begins by describing the evolution of commodity futures exchanges, the institutional structure of futures markets, and the economic and legal aspects of futures trading. It then focuses on the static and dynamic elements of arbitrage theory. The theory of arbitrage is formulated within the context of the conditional statements regarding time and space, and certainty and uncertainty. Four general types of arbitrage models are formulated: (I) Static One-Period Arbitrage Under Certainty (II) Dynamic Two-Period Arbitrage Under Certainty (III) Static One-Period Arbitrage Under Uncertainty (IV) Dynamic Two-Period Arbitrage Under Uncertainty From these models a general arbitrage incentive model is developed. This model serves to measure empirically through time the interspatial price relationships between the New York and London Cocoa Exchanges during the Sterling Devaluation of 1967 and during Sterling crisis periods in which devaluation was not realized. In the cross-sectional time series investigation of devaluation's price effects on the joint cocoa futures markets of London and New York, it was found that certain types of arbitrage activity are ignited by arbitrageurs' expectations that a currency parity change will disturb the interspatial equilibrium basis between London and New York. Empirical evidence indicates that a premium spread between international markets can be interpreted as market anticipation of a permanent upward shift in the interspatial equilibrium basis. A cross-sectional time trend analysis was also conducted on the interspatial spread behavior during different crisis periods in which devaluation was not realized: the 1957 September crisis, the 1961 July crisis, the 1965 November-December crisis, the 1965 July-August crisis, and the 1966 July-September crisis. The results indicate that only when devaluation expectations are present will the interspatial spread compound its premium motion during a Sterling crisis. After examining the non-devaluation Sterling crisis periods, it was concluded that
