Trade credit in Europe: Financial constraint and substitution effect in crisis times
European Financial Management, Volume 29, Issue 1, Page 327-348, January 2023., 2023 Abstract This paper aims to prove whether financial rationing condition leads European enterprises to increase trade debt during the period 2008–2016 and whether companies offering deferred payments to customers obtain trade debt from suppliers. The work contributes to the existing literature by finding new empirical evidence on the substitution and ...

A generalization of Mehta-Wang determinant and Askey-Wilson polynomials [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 Motivated by the Gaussian symplectic ensemble, Mehta and Wang evaluated the $n×n$ determinant $\det ((a+j-i)Γ (b+j+i))$ in 2000. When $a=0$, Ciucu and Krattenthaler computed the associated Pfaffian $\mathrm{Pf}((j-i)Γ (b+j+i))$ with an application to the

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics
Global Change Biology, Volume 29, Issue 2, Page 308-323, January 2023., 2023 Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

The colored Jones polynomials as vortex partition functions
Journal of High Energy Physics, 2021 We construct 3D N $$ \mathcal{N} $$ = 2 abelian gauge theories on S $$ \mathbbm{S} $$ 2 × S $$ \mathbbm{S} $$ 1 labeled by knot diagrams whose K-theoretic vortex partition functions, each of which is a building block of twisted indices, give the colored ...

European Journal of Personality, EarlyView., 2020 Abstract Few studies have examined birth order effects on personality in countries that are not Western, educated, industrialized, rich, and democratic (WEIRD). However, theories have generally suggested that interculturally universal family dynamics are the mechanism behind birth order effects, and prominent theories such as resource dilution would ...

The Journal of Finance, Volume 78, Issue 1, Page 105-139, February 2023., 2023 ABSTRACT We show that over the past half‐century, innovative disruptions were central to understanding corporate defaults. In a given year, industries experiencing abnormally high venture capital or initial public offering activity subsequently see higher default rates, higher segment exits by conglomerates, and higher yields on bonds issued by the ...

Multiple Askey-Wilson polynomials and related basic hypergeometric multiple orthogonal polynomials [PDF]
Transactions of the American Mathematical Society (online),
September 2020, 2019 We first show how one can obtain Al-Salam--Chihara polynomials, continuous dual $q$-Hahn polynomials, and Askey--Wilson polynomials from the little $q$-Laguerre and the little $q$-Jacobi polynomials by using special transformations. This procedure is then extended to obtain multiple Askey--Wilson, multiple continuous dual $q$-Hahn, and multiple Al ...

Journal of the Royal Statistical Society: Series A (Statistics in Society), Volume 185, Issue 4, Page 2234-2276, October 2022., 2022 Abstract Childlessness and socio‐economic well‐being interact dynamically throughout the life course, possibly resulting in an accumulation of socio‐economic (dis)advantage. Methods commonly used to investigate this hypothesis are unable to simultaneously acknowledge that childlessness entails a heterogeneous and processual ‘non‐event’ which ...

A characterization of the Rogers q-hermite polynomials
International Journal of Mathematics and Mathematical Sciences, 1995 In this paper we characterize the Rogers q-Hermite polynomials as the only orthogonal polynomial set which is also 𝒟q-Appell where 𝒟q is the Askey-Wilson finite difference operator.
