The theory of island biogeography and the stability of oceanic reef fish communities

Journal of Fish Biology, EarlyView.
Abstract Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland ...

Short selling ETFs and market performance

Journal of Financial Research, EarlyView.
Abstract We examine short selling activity in leveraged Exchange‐Traded Funds (ETFs) and its impact on underlying index performance. Using a novel measure of ETF short exposure, which includes long positions in inverse leveraged ETFs, we document that high short exposure is associated with positive performance in the subsequent period.

Uninformative news, limited attention and institutional investors

Journal of Risk and Insurance, EarlyView.
Abstract Using the universe of transaction‐level data in the U.S. corporate bond market around uninformative downgrades, we find an abnormal increase in trading volume, abnormal bond returns, and a subsequent reversal. On the contrary, we do not find a reversal for abnormal bond returns associated with informative rating actions.

Inertia Versus Adaptation: Relational Resilience in Buyer–Supplier Relationships Facing Extreme Disruption

Journal of Supply Chain Management, EarlyView.
ABSTRACT This research introduces the concept of relational resilience, which reflects the dynamic capacity of a buyer–supplier relationship to absorb external shocks and continue its core function of exchange. Guided by structural inertia theory (SIT), the research explores how relationship age, exchange volume, and multiplexity contribute to ...

Optimal Portfolio Choice With Cross‐Impact Propagators

Mathematical Finance, EarlyView.
ABSTRACT We consider a class of optimal portfolio choice problems in continuous time where the agent's transactions create both transient cross‐impact driven by a matrix‐valued Volterra propagator, as well as temporary price impact. We formulate this problem as the maximization of a revenue‐risk functional, where the agent also exploits available ...
