Oxford Events, the new replacement for OxTalks, will launch on 16th March. The two-week OxTalks freeze period starts on Monday 2nd March. During this time, there will be no facility to publish or edit events. The existing OxTalks site will remain available to view during this period. Once Oxford Events launches, you will need a Halo login to submit events. Full details are available on the Staff Gateway.
We propose and study the concept of survey rationalizability, that we base on classical item response theories in psychology. Survey rationalizability involves positioning survey questions on a common scale such that, in the main case of attitudinal surveys, each respondent gives higher support to questions that are more aligned with her views. We first demonstrate that ideas from standard revealed preference analysis can be used to characterize when and how dichotomous surveys are rationalizable. We then show that these results readily extend to more general surveys. Furthermore, we investigate the identification of the models and extend the analysis in several directions.
