    This paper devel­ops par­tial-iden­ti­fi­ca­tion and infer­ence for treat­ment effect para­me­ters and the rank­ings of treat­ments in an instru­men­tal vari­able frame­work while impos­ing alter­na­tive monot­o­nic­ity restric­tions. In par­tic­u­lar, we con­sider a dis­crete, multi-val­ued treat­ment, a binary out­come, and a dis­crete, pos­si­bly multi-val­ued instru­ment. We use a lin­ear pro­gram­ming for­mu­la­tion to present a flex­i­ble frame­work and to develop gen­eral results for char­ac­ter­iz­ing the testable restric­tions and the sharp iden­ti­fi­ca­tion of treat­ment effect para­me­ters and the rank­ings of treat­ments in terms of these para­me­ters that fol­low from impos­ing instru­ment exo­gene­ity while addi­tion­ally impos­ing alter­na­tive monot­o­nic­ity restric­tions on how the treat­ments depend on the instru­ments and how the out­comes depend on the treat­ments. Our results nest both ordered and unordered treat­ments. We fur­ther char­ac­ter­ize lead­ing spe­cial cases of our gen­eral analy­sis. We develop meth­ods for simul­ta­ne­ous infer­ence about the con­sis­tency of the observed data with our restric­tions and the treat­ment effect rank­ing when the dis­tri­bu­tion of the observed data is con­sis­tent with our restric­tions. We illus­trate our method­ol­ogy with empir­i­cal appli­ca­tions to the encour­age­ment design of Behaghel, Cre­pon and Gur­gand (2014) inves­ti­gat­ing the effects of pub­lic vs pri­vate job search assis­tance; the RCTs with one-sided non-com­pli­ance of Angrist, Lang and Ore­opou­los (2009) inves­ti­gat­ing the effects of alter­na­tive strate­gies on aca­d­e­mic per­for­mance of col­lege stu­dents and of Blattman, Jami­son, and Sheri­dan (2017) inves­ti­gat­ing the effects cash incen­tives and ther­apy on reduc­ing crime in Liberia; and the RCT with close sub­sti­tutes of Kline and Wal­ters (2016) inves­ti­gat­ing the effects of alter­na­tive early child­hood pro­grams.
