The Uruguay Round Agricultural Agreement of 1993 has been recognized

as one of the ‘‘defining moments’’ (Potter and Ervin 1999: 53) of twen-

tieth-century agricultural policy reform. Emphasizing the link between

domestic agricultural policies and international trade, it committed signa-

tories to reducing domestic subsidies, except for support provisions that

are categorized as non-trade-distorting. These, termed ‘‘Green Box’’ poli-

cies, were ‘‘hotly debated in the negotiations’’ (Josling et al. 1996: 206).

Indeed, looking inside the Green Box reveals room for interpretation regarding the impact of the Uruguay Round on the liberalization of agri-

cultural trade.
