Do consumers benefit from national-brand listings by hard discounters?
研究了德国硬折扣店Lidl增加全国性品牌后对消费者福利的影响，发现不仅Lidl自身、整个市场价格上涨，且贫困消费者损失更大。
Abstract Hard discounters are moving away from an almost exclusive private-label (PL) focus by adding a select set of big-name brands to their otherwise scanty assortments. However, to what extent consumers benefit from this strategy remains unclear. This study quantifies the consumer-welfare impact of adding a select set of leading national brands to hard discounter Lidl’s assortment in the German market. We rely on the economic concept of compensating variation , which reflects the consumer-welfare effect in monetary terms and captures the impact on consumer prices while accounting for consumers’ possible appreciation of more convenient access to big-name brands. Although hard discounters argue that adding big-name brands to their assortment benefits consumers, our results reveal unfavorable price developments, not just at the hard discounter but in the entire market. Importantly, impoverished consumers are hurt more severely, with a monetary loss due to the price increase across the 18 categories in our sample that is about five times larger than for the more affluent.
