Observability in locally vague environments

Contracting in Vague Environments∗

This paper investigates the implications for contracting problems with adverse selection of assuming a more general information structure than usual. The paper applies a choice theoretic framework introduced in Olszewski (2007) and Ahn (2008) a special case of the vague environments in Vierø (2009a) to a canonical principal-agent model with hidden information. The vague environment reflects tha...

Fuzzy Sets and Vague Environments

In this paper we propose a natural approach to handle imprecise numbers as they arise for example from measurements. Fuzzy sets turn out to be a canonical representation for such imprecise numbers that are induced by taking diierent tolerance or error bounds into account. Fuzzy sets are induced by scaling factors that describe the magnitude of the imprecision. On the other, the scaling factors ...

VAGUE RINGS AND VAGUE IDEALS

In this paper, various elementary properties of vague rings are obtained. Furthermore, the concepts of vague subring, vague ideal, vague prime ideal and vague maximal ideal are introduced, and the validity of some relevant classical results in these settings are investigated.

Vague Existence Implies Vague Identity

Vague parts and vague identity

We propose that not all such arguments are on a par. The first section of the paper distinguishes dialectically effective from dialectically ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness – specifically, an argument against objects that are indeterminate in what parts they have – which promises to be dialectically e...
