The present study investigated the effect of taxing high-energy dense products and subsidizing low-energy dense products on changes in calorie consumption. More specifically, we hypothesized that 'more impulsive' individuals were less influenced by such pricing strategies compared to 'less impulsive' individuals. Contrary to our hypothesis, results showed that 'more impulsive' individuals adjusted their calorie consumption with regard to price changes whereas 'less impulsive' participants were less influenced by price changes. Furthermore, taxing high-energy dense products was more successful in reducing calorie consumption than subsidizing low-energy dense products.
本研究调查了对高能量密集型产品征税和对低能量密集型产品补贴对卡路里消耗变化的影响。更具体地说，我们假设“更冲动”的个体比“不那么冲动”的个体受这些定价策略的影响更小。与我们的假设相反，结果表明，“更冲动”的个体根据价格变化调整了他们的卡路里摄入量，而“不那么冲动”的参与者则较少受到价格变化的影响。此外，对高能量密集型产品征税比补贴低能量密集型产品更能成功地减少卡路里摄入。
