posit s s that agen t s making d e e cisions on different t ypes of tr a a nsactions d d o so in a c c ostly way .for exampl e e , farmers deciding s e e ll a parti c c ular crop t o whom bas e e their dec i sions not o o nly on the price they expect to r eceive in e e ach market choice but also on ad d d itional co s s ts related to transac t ing in the s s e markets.
i want to u s s e a pictur e e to illust r ate it. fo r example, g g iven some m m arket chan n n els, farme r s’ choices can be reg a a rded as eq u u ilibrium b e e tween the s s urplus and the additi o o nal costs t hat relate d d to transa c c ting .espe c c ially in d e e veloping c o o untries, h i gh-value c r op produce r s fully pa r ticipate i n n the marke t and the t r ansaction c c ost has be e e n the hard constraint to farmers.furthermo r e, farmers’market ch o o ices can b e e taken as a a choice di l emma of tr a a nsaction c o o st and pro d d uction sur p p lus. conse q q uently, th e e scientifi c c question o o f this res e e arch is ho w w transacti o o n cost aff e e cts plante r s’ choices.
