Disagreement about Inflation Expectations

Analyzing 50 years of inflation expectations data from several sources, we document substantial disagreement among both consumers and professional economists about expected future inflation. Moreover, this disagreement shows substantial variation through time, moving with inflation, the absolute value of the change in inflation, and relative price variability. We argue that a satisfactory model...

the relationship between locus of control and iranian efl university students’ beliefs about language learning

this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...

Active Learning: Disagreement Coefficient

In previous lectures we saw examples in which active learning gives an exponential improvement in the number of labels required for learning. In this lecture we describe the Disagreement Coefficient —a measure of the complexity of an active learning problem proposed by Steve Hanneke in 2007. We will derive an algorithm for the realizable case and analyze it using the disagreement coefficient. I...

Learning and Disagreement in an Uncertain World∗

Most economic analyses presume that there are limited differences in the prior beliefs of individuals, an assumption most often justified by the argument that sufficient common experiences and observations will eliminate disagreements. We investigate this claim using a simple model of Bayesian learning. Two individuals with different priors observe the same infinite sequence of signals about so...
