A bijection between bargraphs and Dyck paths [PDF]
Discrete Applied Mathematics, 2018 Bargraphs are a special class of convex polyominoes. They can be identified with lattice paths with unit steps north, east, and south that start at the origin, end on the $x$-axis, and stay strictly above the $x$-axis everywhere except at the endpoints. Bargraphs, which are used to represent histograms and to model polymers in statistical physics, have

The Economic History Review, EarlyView.Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

Combinatorics of generalized Dyck and Motzkin paths
, 2022 We relate the combinatorics of periodic generalized Dyck and Motzkin paths to the cluster coefficients of particles obeying generalized exclusion statistics, and obtain explicit expressions for the counting of paths with a fixed number of steps of each ...

European Management Review, EarlyView.ABSTRACT Multi‐sided platform (MSP) models have become more relevant for incumbent companies, requiring them to develop MSP engagement strategies. This study sheds light on the complex process incumbents undergo in developing platform strategies. Adopting an inductive research design, we conducted interviews with 37 decision‐makers across 35 incumbent ...

Paving the way for incumbents' digital transformation. A review and research agenda
European Management Review, EarlyView.Abstract Digital transformation is reshaping the competitive landscape by forcing incumbent firms to rethink their strategies, organizational structures, and business models. While a substantial body of literature has explored digital transformation in specific sectors, focusing on various factors and organizational mechanisms, there remains a lack of ...

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

Journal 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.

Calibrated representations of the double Dyck path algebra
, 2023 The double Dyck path algebra $\mathbb{A}_{q,t}$ and its polynomial representation first arose as a key figure in the proof of the celebrated Shuffle Theorem of Carlsson and Mellit.
