PRODUCTION CHOICE IN THE ENGLAND AND WALES DAIRY SECTOR

This paper seeks to develop the understanding of the ways in which factors other than price influence the production decisions of dairy farmers. A theoretical model based on a profit function is used to emphasise the way in which changes in the farm's technological environment will influence its production choices. The theoretical model is used as the basis of an empirical study of production choice in the England and Wales dairy sector. Elasticities and factor biases are reported.     

MANAGEMENT AND SIZE ECONOMIES IN THE ENGLAND AND WALES DAIRY SECTOR

Analyses of size economies in the England and Wales dairy sector have generally been made on the basis of comparisons of input-output measures. These measures have been classified according to input use and farm size and have led to conclusions about efficiency and structural change. This paper examines the influence of managerial ability on economies of size using econometrically estimated long-run average cost (LAC) functions from Milk Marketing Board data for 1980/1. The results show that the LAC curve is U-shaped though skewed to exhibit greater economies than diseconomies of size. Better managed farms are shown to produce any given level of output at lower average cost. Moreover, they have larger optimal levels of output.     

HERD SIZE AND UNIT COSTS OF PRODUCTION IN THE ENGLAND AND WALES DAIRY SECTOR

This paper examines the relationship between herd size and unit costs of production in the England and Wales dairy sector. Following the two-stage estimation procedure of Dawson & Hubbard (1987), longrun average cost (LAC) functions are estimated from cross-section data for five separate years between 1976/7 and 1986/7. Results show that the LAC curves are U-shaped but highly skewed, implying that considerable economies of size are present at low output levels but diseconomies at larger levels are much less marked. Over time, technological change in particular has been shifting the LAC curves downward and to the right and away from the sector's long-run equilibrium. The differential shift of cost curves, depending on the size of production, implies that technological change has been biased in favour of larger herds.     

THE EVOLUTION OF AGRICULTURAL EXTENSION IN ENGLAND AND WALES PRESIDENTIAL ADDRESS

This paper traces the evolution of agricultural extension in England and Wales and reflects on the reasons for the changes which have occurred in its structure, direction and funding. It describes the change from an extension to a consultancy organisation, analyses the effects of such a change, and examines some of the early mistakes in undertaking it. Questions are raised about whether advice paid for by the client improves the focus of extension and enhances the effectiveness of the relationship between adviser and client. It also questions whether Government policies towards agriculture could be equally well carried out by contracting out the work of extension to the private sector.     

FORECASTING MILK OUTPUT IN ENGLAND AND WALES*

This paper evaluates the ablility of an autoregressive integrated moving average (arima) model to forecast monthly milk output before and after the imposition of quotas in April 1984. In the post quota period the standard arima model is modified to a ‘discontinuity’ model allowing the quota to be represented explicitly. It is concluded that for a medium term forecast this is preferable to the standard arima model, whilst for one period ahead forecasts the models are equally good.     

A FORECAST OF MILK SUPPLY IN ENGLAND AND WALES

This paper reports the problems encountered in applying Markov Chain analysis to the Permanent sample of milk producers in England and Wales, and presents predictions obtained for producer numbers and milk output, by regions, for the years 1970/71 and 1975/76. As a consequence of the “pool of entrants” problem, dificulties arise both in estimating the required transition probabilities and in forecasting producer numbers. Solutions to these, and to other problems concerned with obtaining prediction of milk output, from those of producer numbers, are proposed. It is forecast that producer numbers will decline by 18 per cent and 33 per cent by 1970/71 and 1975/76 respectively, with the largest proportional decline occurring among smaller producers. Two forecasts are made of milk supply and these are compared with estimates made by the Milk Morltetiiic Board.     

MARKETING BOARDS AND PRICE FUNDS IN UGANDA, 1950–1960*

Economic development is inextricably linked with the economic institutions of today and yesterday. A study of the policies and practices of these institutions may provide some understanding to the problems of today and tomorrow. This paper investigates the economic eflects of the Lint (Cotton) and Coffee Marketing Boards and their Price Assistance Funds in Uganda between 1950 and 1960. These institutions stood at the very centre of economic life for the vast majority of Ugandan Afiicans and therefore may be expected to have exerted considerable influence over their perception of the economic world. Uganda, along with so many other nations, is just emerging into the world of money, prices, and marketing, just as it has but recently achieved political independence. Indeed, Uganda, though possessing certain historical idiosyncrasies of its own, could almost be an archetypal low income, primary producing country. Now seeking economic development under an African administration, its development eforts must be perceived as prefaced on the earlier institutions of Britain's tutelage.     

LONG-RUN AVERAGE COST CURVES IN THE ENGLAND AND WALES DAIRY INDUSTRY - REPLY

Burton, Ozanne and Collinson (1993) present an interesting comment on the issue of long-run average cost (LAC) in the dairy industry. Since their results essentially substantiate the conclusions of Hubbard (1993), the following points are offered as further thoughts which may be of relevance in any subsequent analysis and estimation.     

QUARTERLY ESTIMATES OF THE DEMAND AND PRICE STRUCTURE FOR MEAT IN NEW SOUTH WALES

Multiple regression estimates of demand and price relationships for fresh beef, lamb and mutton in the N.S.W. livestock auction, wholesale, and retail markets during the period from January 1951 to June 1963 are presented. The results show that direct price elasticities of demand were negative, and of greatest absolute value in the retail market. Mutton is shown to have been a close substitute for beef and lamb, but the latter were not close substitutes with respect to price.     

MARKETING BOARDS AND PRICE FUNDS IN UGANDA, 1950–1960: A COMMENT

In a recent of this Journal, three authors have undertaken a critical survey of the operations of the Uganda Marketing Boards and associated Price Funds in the decade after 1950.*     

COOPERATIVES – UNDER PERFORMERS BY NATURE? AN EXPLORATORY ANALYSIS OF COOPERATIVE AND NON-COOPERATIVE COMPANIES IN THE AGRI-BUSINESS SECTOR

This paper sets out to determine whether agricultural cooperative companies in the UK are more likely to underperform when compared with non-cooperative companies in the same sector. The research indicates, that on the basis of profitability, capital gearing and liquidity, there were no significant differences between the two groups. For the business operational efficiency indicators of sales/working capital ratios, and creditor ratios, there were also no significant differences although, for the indicators of stock turnover and debtor ratios, cooperatives were seen to have significantly higher rates when compared with the non-cooperative companies. The findings of this research reveal that cooperatives do not perform differently to non-cooperatives, despite being required to balance member needs with the attainment of corporate goals.     

AN APPLICATION OF MARKOV CHAINS TO FARM TYPE STRUCTURAL DATA IN ENGLAND AND WALES

Markov Chain methods of projection are applied to farm type structural data derived from the returns in the Annual June Agricultural Census in England and Wales. Three sets of projections, using different assumptions, are made of the numbers of holdings by farm type in 1969 and of the movement of holdings between farm type during 1968/69. These are compared with the actual Census returns for 1969. Use of a four-year average transition probability matrix gives the best overall results on the basis of that comparison and this matirx was then used to project farm type structure in England and Wales for 1971 and 1973. These projections indicate that between June 1969 and June 1973 the number of all holdings with 275 or more standard man days (SMD) will decline; those classified as Mixed, Livestock, and Pigs and Poultry are likely to show the largest proportional declines. Some 50 per cent of holdings are likely to be below the 275 SMD limit. Since the assumptions made may not be fulfilled in every respect, it is unlikely that the outcome in 1971 and 1973 will be precisely as predicted, but the pattern and direction of the projections are likely to hold.     

LIVESTOCK PRODUCTION POLICIES AND MEAT PROCESSING MARGINS: THE CASE OF NEW ZEALAND, 1967-1988*

The New Zealand export meat industry has been through a considerable number of changes in the 1980s. The deregulation of export slaughter facilities, Supplementary Minimum Prices, Producer Board intervention, declining livestock numbers and domestic cost pressures have all affected the performance of the domestically based processing sector. Major changes in market access and demand have influenced off-shore marketing operations, particularly for sheepmeats. Additionally, there has been a change in the type of meat exported with a greater proportion of further processed product shipped in recent years. As an example of the impact of these developments on livestock producers, the producer share of the United Kingdom wholesale market return for a representative prime lamb carcase has fallen from 40 per cent in 1978 to 25 per cent in 1988. In this article the pattern of intervention in the New Zealand pastoral meat industries from the mid-1960s is detailed, emphasising the different environments of the beef and sheepmeat enterprises. Then the principal factors influencing domestic processing margins for these products are empirically examined. Alternative model specifications and alternative estimation techniques are compared and contrasted. The results of these analyses are discussed in terms of the historical patterns of assistance and structural change, and in terms of current rationalisation pressures on the meat processing sector.
