Non-Fundamental Expectations and Economic Fluctuations: Evidence from Professional Forecasts [PDF]
It is theoretically possible that non-fundamental idiosyncratic shocks to agents’ rational expectations are a source of economic fluctuations. Studies using data on consumer and investor sentiment suggest that this is indeed a significant source of ...

Explainable deep learning self‐supervised vision transformer for fundus‐based myopia classification
Acta Ophthalmologica, EarlyView.Abstract Purpose To develop and validate a self‐supervised vision transformer (ViT) for automated three‐class classification of Normal, High Myopia (HM), and Pathologic Myopia (PM) from colour fundus photographs, with anatomically faithful interpretability. Methods A DINOv2 self‐supervised ViT was fine‐tuned using a two‐stage transfer‐learning protocol

Sunspots in global games: Theory and experiment [PDF]
, 2018 We solve and test experimentally a global-games model of speculative attacks where agents can choose whether to read, at a cost, a payoff irrelevant (sunspot) announcement.

Acta Ophthalmologica, EarlyView.Abstract Purpose To define interdevice differences in quantitative outer retinal biomarkers across three spectral‐domain (SD) optical coherence tomography (OCT) devices in geographic atrophy (GA). Methods Patients with GA prospectively underwent imaging using Spectralis (Heidelberg Engineering), Cirrus (Zeiss) and Maestro (Topcon) OCT devices ...

The Power of Sunspots: An Experimental Analysis [PDF]
We present an experiment in which extrinsic information (signals) may generate sunspot equilibria. The underlying coordination game has a unique symmetric non-sunspot equilibrium, which is also risk-dominant.

Acta Ophthalmologica, EarlyView.Abstract Purpose This study investigated the self‐perceived competence, knowledge, confidence and attitudes of the UK optometric workforce with regard to nutritional advice for patients. Methods A validated questionnaire (NUTrition COMPetence) was used to survey the optometric workforce, which was adapted to UK optometric practice and nutritional ...

Sunspots do matter: a simple disproof of Mas-Colell [PDF]
Mas-Colell conjectured that, for economies admitting a unique deterministic equilibrium, sunspot equilibria that 'matter'' would not exist.

Acta Ophthalmologica, EarlyView.Abstract Background Manual diabetic retinopathy (DR) grading may prefer certain regions and underestimate others. It is unclear if inexperienced graders' initial marking strategy reflects a specialist's marking pattern. Aims By the virtual ocular learning platform (VIOLA), we evaluated if initial DR‐lesion markings among inexperienced graders spatially

Acta Ophthalmologica, EarlyView.Abstract This systematic review and meta‐analysis synthesized the reported frequency of concurrent macular neovascularization (MNV) among selected eyes with author‐defined shallow irregular retinal pigment epithelium (RPE) elevations in age‐related macular degeneration (AMD) and chronic central serous chorioretinopathy (CSC).
