Exposure to Left‐Tail Risk, Risk Appetite, and Mutual Fund Flows
Financial Review, EarlyView.ABSTRACT Using a measure of aggregate tail risk, we show that a fund's sensitivity (exposure) to tail risk negatively affects the fund flows and the fund's performance. Further, a fund's tail risk sensitivity relates positively to the left‐tail risk measures of the fund.

The Short and the Long of It: Stock‐Flow Matching in the US Housing Market
International Economic Review, EarlyView.ABSTRACT From 2006 until 2020, the probability of selling a house in the U.S. declined sharply after listing for 2 weeks. Moreover, sales within the first 2 weeks of listing (“quick sales”) and sales happening afterward (“slow sales”) behaved differently over the housing cycle.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces
International Statistical Review, EarlyView.Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Stein complements in compact Kähler manifolds
Mathematische AnnalenGiven a projective or compact Kähler manifold X and a (smooth) hypersurface Y, we study conditions under which $X \setminus Y$ could be Stein. We apply this in particular to the case when X is the projectivization of the so-called canonical extension of the tangent bundle $T_M$ of a projective manifold M with Y being the projectivization of $T_M ...

Governance Gambit: The Unforeseen Impact on Disclosure Quality
Journal of Business Finance &Accounting, EarlyView.ABSTRACT Extensive research in earnings management has focused on understanding managerial bias and its impact on disclosure quality. This study extends this literature by introducing a model of earnings management with dual oversight mechanisms. The first is internal supervision, such as internal controls and audit committees, which operates before ...

Journal of Applied Entomology, EarlyView.ABSTRACT Reliable laboratory rearing of Frankliniella occidentalis is critical for experimental consistency in entomological research. This study validates and optimises three small‐scale rearing systems initiated from a single female thrips using various organic fruits, flowers and pollen as feed, along with moist cotton, blotting paper and ...

An Integral Representation of Functions on Stein Manifold
, 2000 利用文献 [1 ]在 Cn空间中建立抽象积分表示的思想及 Henkin和 Leiterer在文献 [2 ]中构造的Stein流形上积分核的方法 ,将 Stein流形上已有的一些积分表示进行拓广 .得到 Stein流形上具逐块光滑边界的相对紧开集 D上 f连续且 -f也连续的一个抽象积分表示 ,这个积分表示的特点是含有m个可供选择的 Leray截面和 m个可供选择的实参数 ,当适当选取其中的 Leray截面和实参数时 ,不但可得到 Stein流形上已有的 B- M公式、Leray- Stokes公式 ...

Uniform estimates of solutions for @-equations on Stein manifolds [PDF]
, 2005 众所周知Stein流形是一个极其重要的流形,在Stein流形上有很多非常数的全纯函数.Cn就是一个Stein流形,所以在Stein流形上研究多元复分析是很自然的.积分表示方法是多元复分析的主要方法之一,它的主要优点是象单复变数的Cauchy积分公式一样便于估计.过去人们已经得到了许多Cn以及Stein流形上为解@--方程所需的积分公式,由此也得到了一些(0,q)型微分形式的@--方程解的Hölder估计和一致估计.在前人的基础上作者利用Demailly和Laurent--Thiebaut[8 ...

Bott-Chern harmonic forms on Stein manifolds
, 2018 Let M be an n-dimensional d-bounded Stein manifold M, i.e., a complex n-dimensional manifold M admitting a smooth strictly plurisubhar-monic exhaustion ρ and endowed with the Kähler metric whose fundamental form is ω = i∂∂ρ, such that i∂ρ has bounded L∞
