食品在其效用方面具有一些可能导致市场失灵的特殊性质:负效用信息暴露的延滞性、负效用的不可逆性、消费者对食品未来正效用与负效用的贴现率的非对称性以及食品效用信息的客观隐藏性。据此可分析得出:食品新技术可能的潜在负效用越大、该负效用产生的概率越大、负效用信息暴露越滞后、确认负效用信息所需试验成本越低、新技术所带来的显性福利增量越小,则该新技术的完全自由放任式市场推广方案就越有可能劣于政府依据试验结果审批后再市场推广的方案。本文结果支持对食品新技术推广给予更严格的政府规制。
Food has some special properties in terms of their utility that may lead to market failure: the delay of the exposure of negative utility information, the irreversibility of negative utility, the asymmetry of consumers’ discount rate of positive and negative effect on food future, and food utility information Objective hidden. Based on this analysis, it is concluded that the greater the potential negative effect of the new food technology, the greater the probability of negative effect and the more delayed the exposure of negative effect information. The lower the test cost for confirming the negative effect information, the new technology brings The smaller the incremental explicit benefit, the more likely the complete laissez-faire program of the new technology is to be outperformed by the government’s re-marketing plan based on trial results. The results of this article support tighter government regulations on the promotion of new food technologies.
