WORDS, DYCK PATHS, TREES, AND BIJECTIONS [PDF]

open access: yes, 2001
In \cite{BaDeFePi96} the concept of nondecreasing Dyck paths was introduced. We continue this research by looking at it from the point of view of words, rational languages, planted plane trees, and continued fractions. We construct a bijection with planted plane trees of height $\le 4$ and compute various statistics on trees that are the equivalents of

The Effects of Country Governance Quality on Corporate Sustainability and Ethical Behaviour

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT Using institutional theory, we examine how country governance affects two ESG outcomes: ESG performance and ESG controversies. With Refinitiv/LSEG data for ~146,000 firm‐years in 86 countries (2002–2023) and World Bank WGI, we apply a Mundlak within/between decomposition to test complementarity versus substitution (performance) and prevention ...

Changes in Audit Risk Responses During Times of Crisis: Evidence From Key Audit Matters in China

open access: yesInternational Journal of Auditing, EarlyView.
ABSTRACT This study examines how auditors adjust their risk responses to the COVID‐19 pandemic, an exogenous shock that heightened uncertainty and constrained access to audit evidence. Using manually collected audit‐procedure disclosures from Key Audit Matters (KAMs) for Chinese A‐share listed companies from 2017 to 2022, we employ a generalized ...

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

open access: yesJournal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Left to right maxima in Dyck Paths

open access: yes, 2021
In a Dyck path a peak which is (weakly) higher than all the preceding peaks is called a strict (weak) left to right maximum. We obtain explicit generating functions for both weak and strict left to right maxima in Dyck paths. The proofs of the associated asymptotics make use of analytic techniques such as Mellin transforms, singularity analysis and ...

Incumbent‐Born B2B Platforms: Organizational Boundary Dynamics in Platform Creation

open access: yesJournal of Product Innovation Management, EarlyView.
ABSTRACT This study examines the dynamics of organizational boundaries in B2B industry platform creation through an in‐depth single‐case study. Specifically, we address the question: How do B2B firms redefine their organizational boundaries when shifting from a pipeline model to an industry platform?

The location of the first maximum in the first sojourn of a Dyck path

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
For Dyck paths (nonnegative symmetric) random walks, the location of the first maximum within the first sojourn is studied. Generating functions and explicit resp. asymptotic expressions for the average are derived.
