Examples include long-run risk\u2013return relationships in dynamic asset pricing models and components of marginal utility in external habit formation models. This paper provides identification conditions for positive eigenfunctions in nonparametric models. Identification is achieved if the operator satisfies two mild positivity conditions and a power compactness condition. Both existence and identification are achieved under a further nondegeneracy condition. The general results are applied to obtain new identification conditions for external habit formation models and for positive eigenfunctions of pricing operators in dynamic asset pricing models.<\/jats:p>","DOI":"10.1017\/s0266466614000668","type":"journal-article","created":{"date-parts":[[2014,10,9]],"date-time":"2014-10-09T07:44:46Z","timestamp":1412840686000},"page":"1310-1330","source":"Crossref","is-referenced-by-count":13,"title":["NONPARAMETRIC IDENTIFICATION OF POSITIVE EIGENFUNCTIONS"],"prefix":"10.1017","volume":"31","author":[{"given":"Timothy M.","family":"Christensen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,10,9]]},"reference":[{"key":"S0266466614000668_ref9","doi-asserted-by":"publisher","DOI":"10.1017\/S0266466610000368"},{"key":"S0266466614000668_ref24","volume-title":"Linear Operators Leaving Invariant a Cone in a Banach Space","author":"Kre\u012dn","year":"1950"},{"key":"S0266466614000668_ref7","unstructured":"Christensen T.M .
