An in-store experiment on the effect of accessibility on sales of whole grain and white bread in supermarkets.

The effect of convenience on bread sales was investigated over two periods in two supermarkets. During period 1 (week 43-49, 2013) whole grain bread was presented conveniently near the entrance whereas white bread was located further away (healthy first) in one of the supermarkets whereas white bread was located near the entrance in the other supermarket (healthy last). During period 2 (week 5-9, 2014) this order was reversed. The number of units of five categories of bread, including whole grain and white bread, was registered per day.

本研究针对两家超市的两个时段，调研了购物便利性对面包销量的影响。在时段1（2013年第43至49周），其中一家超市将全麦面包（whole grain bread）陈列在入口附近的便捷位置，而白面包（white bread）则放置于较远区域（健康优先策略）；另一家超市则将白面包陈列在入口附近，全麦面包置于较远处（健康后置策略）。在时段2（2014年第5至9周），两家超市的面包陈列顺序均进行了反转。研究人员每日对包括全麦面包与白面包在内的五大类面包的销售单元数量进行了登记统计。
