The Price and Welfare Consequences of the British Sugar Act of 1846
研究1846年英国糖税法案对消费者和殖民及非殖民生产者的价格与福利影响，发现与奴隶制经济体贸易加剧带来了英国消费者福利提升和效率改善。
Research on trade liberalization frequently overlooks the effects on third-party welfare. This paper studies a historically tragic third-party consequence of a special case of tariff reform: the British Sugar Act of 1846. Using a new database of monthly observations of prices and import volumes for the period 1840–1853, I estimate the price and welfare effects of the passage of the Sugar Act for consumers and colonial and noncolonial producers. Considerable consumption gains for British consumers and a reduced deadweight loss were derived from the intensification of trade with the slave economies.
