This paper uses a leading UK supermarket’s loyalty card database to assess the effectiveness and impact of the 2004 UK reduced salt campaign. We present an econometric analysis of purchase data to assess the effectiveness of the Food Standard Agency’s (FSA) ‘reduced salt campaign’. We adopt a general approach to determining structural breaks in the time series of purchase data, using unit root tests whereby structural breaks are endogenously determined from the data. We find only limited evidence supporting the effectiveness of the FSA’s reduced salt campaign. Our results support existing findings in the literature that have used alternative methodologies to examine the impact of information campaigns on consumer choice of products with high salt content.

食用富含盐的产品：英国减少食盐运动的影响。

本文使用英国一家领先的超级市场的​​会员卡数据库来评估2004年英国减盐运动的有效性和影响。我们提供对购买数据的计量分析，以评估食品标准局（FSA）的“减盐运动”的有效性。我们采用一种通用方法来确定购买数据时间序列中的结构性断裂，使用单位根检验，从而根据数据内生地确定结构性断裂。我们发现只有有限的证据支持FSA减盐运动的有效性。我们的结果支持文献中已有的发现，这些发现已使用替代方法来研究信息运动对消费者选择含盐量高的产品的影响。
