Juan valdez, a coffee farmer in colombia, sells his coffee to cafe emporium, a u. s. firm which specializes in gourmet coffee blends. what must be true of this arrangement? when juan and other farmers in colombia sell their coffee beans to foreigners, they gain in the short run, but in the long run will only impoverish their nation as a whole. juan thinks he is better off with this contract, but in reality the wealthy american buyer is taking advantage of juan's naiveté. while this arrangement is good for juan, he would be even better off if the government had negotiated the contract because they could have gotten a better price for juan. all three of these statements must be true. none of these statements must be true.
