We provide a rationale for ambiguous communication. We do so by considering a cheap talk game in which a (possibly ambiguity averse) sender (S) able to randomize according to unknown probabilities faces an ambiguity averse receiver (R). We show that under fairly general circumstances, there exist equilibria featuring Ellsbergian communication strategies that allow both S and R to obtain a highe...

The Working Papers should not be reported as representing the views of the Banco Central do Brasil. The views expressed in the papers are those of the author(s) and do not necessarily reflect those of the Banco Central do Brasil. This paper characterizes ambiguity averse preferences in the absence of the completeness axiom. We axiomatize multiple selves versions of some of the most important ex...

We show that an increase in uncertainty about the probability of being audited (ambiguity) increases tax compliance for ambiguity-averse taxpayers but reduces compliance for ambiguity lovers. Because experimental evidence reveals considerable heterogeneity with respect to ambiguity preferences, we conclude that fostering uncertainty about the probability of being audited may not be an effective...

Readers are sensitive to the fact that verbs may allow multiple subcategorization frames that differ in their probability of occurrence. Although a verb s overall subcategorization preferences can be described probabilistically, underlying non-random factors may determine those probabilities. One potential factor is verb semantics: Many verbs show sense differences, and a verb s subcategorizati...

Abstract The present paper deals with a syntactic ambiguity in Numenius’ Fr. 30, 9 and proposes new reading. According to most scholars, this fragment Numenius tries identify Egyptian gods human souls descending into generation. Instead, I argue that, since theology psychology are different topics 3, is rather talking about the interrelation of process metempsychosis.

Graphophonemic conversion rules are posited by models of word reading in order to handle reading of unknown letter strings such as nonwords. Graphophonemic conversion is thought to be relied upon by readers especially in more transparent orthographies such as Greek. Here we test the hypothesis that Greek nonwords are read using rules, by exploiting a case of orthographic ambiguity found in Gree...

This study presents the first two ERP reading studies of comma-induced effects of covert (implicit) prosody on syntactic parsing decisions in English. The first experiment used a balanced 2 × 2 design in which the presence/absence of commas determined plausibility (e.g., John, said Mary, was the nicest boy at the party vs. John said Mary was the nicest boy at the party). The second reading expe...

I present a semantic analysis of collective-distributive ambiguity, and resolution of such ambiguity by model-based reasoning. This approach goes beyond Scha and Stallard [17], whose reasoning capability was limited to checking semantic types. My semantic analysis is based on Link [14, 13] and Roberts [15], where distributivity comes uniformly from a quantificational operator, either explicit (...
