| Results of a study of sow inventory and pig supply responses are reported in this paper. Annual time series data (1953-54 to 1974-75) were used to estimate a two equation recursive model for Australia. Tests for structural changes in sow inventory response were conducted over time for Australian data and between regions for Victorian data. Single period lags of sow inventories, pig prices and feed prices were used to estimate short-run and long-run elasticities. The results yield information on pig supply additional to that presently available in the published literature. Evidence of structural change is reflected in elasticities of sow inventory response. While the hypothesis of structural change is statistically supported for regional aggregates of... |

| Applied economists have devoted significant resources to the econometric estimation of demand and price parameters of markets for agricultural products. This paper provides a review of research in this area for the Australian domestic market. Identified publications are classified on the basis of various levels of aggregation over products and markets and are evaluated in terms of the use of economic theory, econometric methods and data. In the final section of the paper there is a discussion of some questions and problems arising from the existing literature, and the implications for future research in this area. |

| A simulated model of an auction market is developed showing the relationship between the variation in valuations, the price variation and the number of independent bidders in the market. Average prices paid in a market with two or three bidders are less than average valuations. Average prices are progressively greater than average valuations as the number of bidders increases beyond four. Some applications of this model in the Australian wool market are discussed. |
