Subject-defined vs. experimenter-defined conflict

Algebras defined by homomorphisms

Let $mathcal{R}$ be a  commutative ring with identity, let $A$ and $B$ be two $mathcal{R}$-algebras and $varphi:Blongrightarrow A$ be an $mathcal{R}$-additive algebra homomorphism. We introduce a new algebra $Atimes_varphi B$, and give some basic properties of this algebra. Generalized $2$-cocycle derivations on $Atimes_varphi B$ are studied. Accordingly, $Atimes_varphi B$ is considered from th...

The Life Cycle Model with Recursive Utility: Defined benefit vs defined contribution

We analyze optimal consumption and portfolio choice when the agent takes the market as given, with applications to pension insurance. First, we recall the results for the conventional additive and separable expected utility model. We explain why this model is not viable in a temporal context. As a consequence, when confronted with real data this theory meets with several conflicting implication...

Self-Terminated vs. Experimenter-Terminated Memory Search

In most free-recall experiments, participants are given a preset amount of time to search memory. Recently, several studies have examined retrieval in an open-interval design in which the participant, not the experimenter, determines when to terminate memory search. The present study performs the first direct comparison between participant-terminated and experimenter-terminated retrieval. No di...
