SUPPLY RESPONSES IN CROP AND LIVESTOCK PRODUCTION

This paper is concerned with regression models of time series data, where the data relate to market level aggregates not to individual farms or groups of farms. It presents ideas and preliminary explorations rather than final results. Some aspects of Nerlove's agricultural supply response model are examined, and some conceptual and practical problems discussed. Two general models are then proposed, one for annual crops and one for livestock products. In the time available little empirical work could be undertaken, so that the usefulness, or otherwise, of the thoughts and models presented rests on rather little evidence.
