摘要 Abstract of the paper	An online firm competes with two local offline firms when market sizes in term of demand intercepts are different, and online transaction suffers a distaste cost but benefits from a lower unit cost. Third-degree online price discrimination is shown to be welfare-improving when the scale of the cross demand parameter is large, even though the total quantities of either online or offline products are unchanged. However, if the online firm competes with a chain-store firm who sets uniform prices in all local markets, allowing online price discrimination is always welfare-worsen. Extensive discussions on the case of different slopes and multiple local markets are also provided.
