Summary
Entry to the European Economic Community in 1973 brought about fundamental changes in the policy instruments applied to the United Kingdom's cereal sector. Prior to entry, grain prices were largely determined by the price of imported cereals, and farmers' revenue was protected by a system of Deficiency Payments. Once in the ECf the UK market was supported by market intervention, with the price of imports raised by a variable import levy. This period of change provided a unique opportunity to examine a commodity market undergoing a fundamental change in terms of institutional management and price behaviour. The investigation proceeds by first suggesting several anticipated developments in the period 19731979. The observed behaviour of the markets is then investigated using causality tests and spectral analysis. The expected behaviour is compared with the results, and conclusions are drawn about the effects of the institutional management of the market.
