提供产品信息是否会影响价格补贴对购买的影响？这个问题对于发展中国家的卫生产品尤其重要，在这些国家，信息宣传和价格补贴都是常见的政策工具。我们在赞比亚进行了一项现场实验，发现提供有关产品新版本的信息会显着增加价格补贴对使用的影响。单独来看，信息操纵对需求没有显着影响，而价格补贴则大幅增加了需求。然而，单独评估任何一种干预措施都无法体现两者之间的显着互补性。 (C) 2013 Elsevier B.V. 保留所有权利。
Does providing information about a product influence the impact of price subsidies on purchases? This question is particularly relevant for health products in developing countries where both informational campaigns and price subsidies are common policy instruments. We conduct a field experiment in Zambia and find that providing information about a new version of a product significantly increases the impact of price subsidies on take-up. Taken alone, the information manipulation has no significant impact on demand while the price subsidy substantially increases demand. However, the evaluation of either intervention in isolation fails to capture the significant complementarity between the two. (C) 2013 Elsevier B.V. All rights reserved.
