Hassle Costs and Price Discrimination: An Empirical Welfare Analysis
研究了汽水在可重复灌装和不可重复灌装瓶子中的销售，发现价格敏感的消费者更不在意购买可重复灌装瓶的不便，零售商可利用此细分市场进行价格歧视；若取消可重复灌装瓶，消费者福利和利润将分别下降12.61%和4.21%。
This paper studies a market where soda is sold in both refillable and nonrefillable bottles. Purchasing refillables is inconvenient but cheaper. Using a discrete choice model, I find that price-sensitive customers put less weight on the inconveniences of purchasing refillables. This implies that a retailer can target lower prices to price-sensitive customers using the refillable segment. I evaluate the overall welfare consequences of this market segmentation and find that both customer welfare and profits would decrease (by 12.61 and 4.21 percent, respectively) if the refillables were removed, as there would be an important market-shrinkage effect.
