英文文献摘要：
The main objective of this study was to analyze the effect of advertising on social welfare in a perfectly competitive market where the level of advertising is chosen by a social planner. The theoretical model revealed that social planner sponsored advertising that increases the equilibrium price of the advertised good can increase society’s welfare if the effect of advertising in consumers’ utility is higher than the consumer welfare reducing price effect (producer welfare is increased by the same amount as the reduction in consumer welfare). The empirical illustration focuses on the U.S. state of South Carolina “buy local” food products campaign. The findings suggest that this government sponsored advertising campaign increases total welfare.

本研究的主要目的是分析在完全竞争市场中广告对社会福利的影响，其中广告水平是由社会策划者选择的。理论模型显示社会规划者赞助广告,增加了广告的均衡价格会增加社会福利,如果效果好广告的消费者的效用高于消费者福利减少价格效应(生产者福利增加了相同数量的减少消费者福利)。这个实证案例集中在美国南卡罗来纳州的“购买本地食品”运动上。调查结果表明，政府赞助的广告活动增加了总福利。
