Price and yield effects of spill‐overs in international agricultural research: evidence from ICRISAT and Australia
研究了国际农业研究（如ICRISAT）对发展中国家生产力提升的溢出效应如何影响澳大利亚的高粱和鹰嘴豆价格与产量，并分析了生产者与消费者的福利变化。
Abstract International agricultural research aimed at improving productivity in developing countries also has spill‐over effects on developed countries. Research that affects the supply of commodities is also likely to affect the world price of tradeable commodities. In this paper, the effects of spill‐overs to Australia from successful cost‐reducing research into sorghum and chickpeas at die International Crops Research Institute for the Semi‐Arid Tropics (ICRISAT) aimed at developing countries are assessed. Genetic materials developed and distributed through ICRISAT are used in Australia to increase productivity. The price‐reducing effects of successful research are incorporated into the analysis of spill‐over impacts on productivity. The net effects on welfare for producers and consumers of sorghum and chickpeas in Australia and the Rest of the World (ROW) are identified. The consequences of the impacts are discussed and the implications for further funding of international agricultural research are also discussed.
