A CROSS‐COMMODITY APPRAISAL OF DEMAND‐RAISING RESEARCH BENEFITS: PORK AND CHICKEN IN AUSTRALIA
开发了一个多商品模型来评估提升某商品需求的研究收益，应用于澳大利亚猪肉和鸡肉产业，发现考虑跨商品效应时猪肉生产者收益更大、消费者收益更小。
A multi‐commodity model is developed for evaluating the gains from research which raises the demand for a commodity, and applied to the pig and chicken industries in Australia. The major finding is that the gain to pork producers is larger, and the gain to consumers smaller, with a cross‐commodity consideration than without. Bigger differences in results are observed with larger values of the cross‐price elasticity between pork and chicken, and with a larger shift in demand for chicken. However, the aggregate benefits to the Australian pig industry are not significantly affected by price changes in the market for chicken. The implication of the analysis is that, by ignoring the cross‐market feedback between commodities closely related in consumption, consumers (or taxpayers) of the commodity experiencing a rise in demand may bear a higher‐than‐optimal outlay on public research directed to increasing the demand for that commodity.
