This model generalizes some existing possibilistic saving models and from them, by a particularization, one can obtain new saving models. In the paper, sufficient conditions are set for the presence of potential risk to increase optimal saving levels and an approximation formula for optimal saving is demonstrated. Particular models for a few concrete expected utility operators are analyzed for triangular fuzzy numbers and CRRA-utility functions.<\/jats:p>","DOI":"10.3390\/axioms9010017","type":"journal-article","created":{"date-parts":[[2020,2,10]],"date-time":"2020-02-10T11:48:51Z","timestamp":1581335331000},"page":"17","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Optimal Saving by Expected Utility Operators"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8536-5636","authenticated-orcid":false,"given":"Irina","family":"Georgescu","sequence":"first","affiliation":[{"name":"Academy of Economic Studies, Department of Economic Cybernetics, Pia\u0163a Romana No 6 R 70167, Oficiul Postal 22, 010552 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jani","family":"Kinnunen","sequence":"additional","affiliation":[{"name":"Department of Information Systems, \u00c5bo Akademi University, Tuomiokirkkotori 3, 20500 Turku, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"465","DOI":"10.2307\/1879518","article-title":"Saving and uncertainty: The precautionary demand for saving","volume":"82","author":"Leland","year":"1968","journal-title":"Q.
