碩士 / 國立臺灣大學 / 農業經濟學研究所 / 92 / The offshore cage aquaculture is encouraged by the Taiwan government in recent years. Due to northeastern monsoon in winter and typhoon in summer, however the offshore cage aquaculture is operated under high risk. Strengthening the research and development of production technology and equipment, reducing the production cost, and introducing an insurance, are ways to enhance the competitiveness of the industry and to abate the uncertainty faced by producers.
Past studies indicate that introducing an insurance could lower the risk having by aqua-farmers. Some also point out that insurance will influence farmer’s production decisions as well. The degree of impacts depends on the risk attitudes farmers hold. Since the cobia is the major culture species in offshore cage aquaculture in Taiwan, the objectives of this research are to investigate the risk attitudes of the cobia cage aquaculture producers, and examine the impacts of implementing insurance on cobia cage aquaculture producers’ production decisions.
Our findings are as the following:
1. Under 10% significance level, the null hypothesis assuming the risk attitudes of offshore cage aquaculture producers are constant absolute risk aversion producer cannot be rejected.
2. Prior to adopting insurance, the higher the degree of risk aversion of the producer is, the lower the optimal feed input used. With insurance, all cobia cage aquaculture producers will increase the feed input.
3. When the insurance level is higher than 70%, the optimal feed input used will decrease gradually. The decrease rate is increase as the insurance level rise.
4. Under the certain insurance level, the higher the degree of the risk aversion of the producer is, the stronger the impact on the production decision.
5. If the cost of insurance is paid by the government, on the financial and social welfare concerns, the revenue insuranceis better than yield insurance. Moreover, insurance level better be under 70%.
