Optimizing equity and efficiency in the aerial firefighting resource allocation problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This study addresses the aerial firefighting resource allocation problem, formulated as the strategic prepositioning of a heterogeneous aerial firefighting fleet across capacity‐constrained airbases. A novel bi‐objective model is proposed that simultaneously optimizes efficiency (aggregate risk‐weighted accessibility) and equity (minimized ...

A hybrid robust‐stochastic optimization approach for green hydrogen production planning under wind power forecast uncertainty

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from

Body size, functional form and environmental correlates of maximum longevity in marine‐occurring fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Maximum longevity varies widely among marine‐occurring fishes, but the form of its relationship with body size and the contribution of broad environmental gradients remain uncertain. We analysed 757 species, using maximum length as the primary size metric and completed mass only in sensitivity analyses.

Macroprudential Policy in the Euro Area

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract This paper examines the development and impact of macroprudential policies in the euro area. We construct a novel index that captures the stance of macroprudential policy, and we highlight its main stylized facts since the inception of the euro in 1999. We combine a narrative approach and a structural VAR method to show that both unanticipated

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Networked Regional Resilience: Diffusion of Risk and Adaptation Across Interconnected Regions

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT Regions face not only direct exposure to economic and physical shocks but also indirect consequences of actions in interconnected regions. This paper examines how socio‐spatial networks shape regional resilience to contagious shocks through dynamic feedback between risk diffusion and adaptation diffusion.
