Title:Optimal consumption choice with intolerance for declining standard of living PDF Logo
Authors:Riedel, Frank
Issue Date:2007
Series/Report no.:Working papers // Institute of Mathematical Economics 394
Abstract:Duesenberry introduced the notion of a ratchet investor who does not tolerate any decline in her consumption rate. We connect the demand behavior of such an agent to the behavior of standard time-additive agents. A ratchet investor demands the running maximum of the optimal plan a conventional time-additive investor with lower initial wealth would choose.
