Superintegrability of the monomial Uglov matrix model
European Physical Journal C: Particles and FieldsIn this paper we propose a resolution to the problem of $$\beta $$ β -deforming the non-Gaussian monomial matrix models. The naive guess of substituting Schur polynomials with Jack polynomials does not work in that case, therefore we are forced to look ...

Market Uncertainty, Investor Sentiment, and the Beta Premium
Financial Review, EarlyView.ABSTRACT This paper provides new insights into how time‐variation in the beta premium is related to popular measures of market uncertainty and sentiment; specifically, the CBOE's VIX and the sentiment index of Baker‐Wurgler (2006). We show that the beta premium: (1) increases nonlinearly with uncertainty, rising significantly only when VIX exceeds a ...

Driving Navigation in Older Adults Across the Alzheimer's Disease Continuum
Journal of the American Geriatrics Society, EarlyView.ABSTRACT Background and Objectives To examine whether time from amyloid positivity (amyloid time), a continuous measure of biological Alzheimer's disease (AD) progression, is associated with differences in navigation‐related driving behaviors among older adults.

Simple representations of BPS algebras: the case of $$Y(\widehat{\mathfrak {gl}}_2)$$ Y ( gl ^ 2 )
European Physical Journal C: Particles and FieldsBPS algebras are the symmetries of a wide class of brane-inspired models. They are closely related to Yangians – the peculiar and somewhat sophisticated limit of DIM algebras. Still they possess some simple and explicit representations.

Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT Leveraging over 40 million residential electricity billing records from more than one million meters in Ethiopia, we test whether consumers respond to marginal prices at kink points under an increasing block tariff (IBT). We exploit a unique institutional setting in which two distinct billing systems (manual postpaid and automated prepaid ...

Journal of High Energy PhysicsWe reinvestigate the Calogero-Sutherland-type (CS-type) models and generalized hypergeometric functions. We construct the generalized CS operators for circular, Hermite, Laguerre, Jacobi and Bessel cases and establish the generalized Lassalle-Nekrasov ...

Marital Dissolution, Repartnering, and the Realization of Fertility Desires in Sub‐Saharan Africa
Population and Development Review, EarlyView.Abstract Women who experience union disruption in sub‐Saharan Africa tend to have lower fertility than those in stable unions. It remains unclear, however, whether this pattern reflects lower fertility desires, constrained opportunities to achieve desired fertility, or both.
