Forecasting models for the U.K. pig sector
Calvert, Neill W. (1989) Forecasting models for the U.K. pig sector. PhD thesis, University of Nottingham.
In this thesis, forecasting models for the UK pigmeat sector are built using various methodologies with particular interest being paid to the relative forecasting ability of time series models compared with the performance of biological and econometric methodologies. The main determinant of the supply of pigmeat in the UK is the size of the breeding herd, the quantity of meat itself being directly attributable to the number of fat pigs slaughtered and to a lesser extent cullings of older sows and boars from the breeding herd. These three key variables are the ones modelled in this thesis. Prior to building forecasting models an explanation is given of the system underpinning the pig sector, in terms of the biology of the breeding herd pig, the mechanism of how supply responds to prices, and consideration of the well documented 'pig cycle'. Thus, the workings of the biological and economic mechanisms are described in the context of an equilibrium framework before the relevant models are built.
