ENSO impacts on low wind power events: A long‐term data‐driven analysis using TabNet

open access: yesEnergy Conversion and Economics, EarlyView.
Abstract As power systems transition towards decarbonised energy mixes with increasing wind penetration, prolonged low‐wind‐power (LWP) events have emerged as a critical source of adequacy risk. However, a comprehensive analysis of LWP events remains constrained by the scarcity of long‐term historical wind‐power generation records in regions with high ...

Gandy Direct-Limit Theorem: Polynomial-Time Prediction on Operator-Generated Networks

open access: yesIEEE Access
Predictive analytics increasingly runs over structures that grow without bound, such as logistics networks, digital twins, and knowledge graphs, where queries carry hard latency budgets yet the deployed guarantees are only statistical. We develop a worst-

Envelope theorems for non-smooth and non-concave optimization [PDF]

open access: yes, 2012
We study general dynamic programming problems with continuous and discrete choices and general constraints. The value functions may have kinks arising (1) at indifference points between discrete choices and (2) at constraint boundaries. Nevertheless, we establish a general envelope theorem: first-order conditions are necessary at interior optimal ...

The envelope theorem: numerical examples

open access: yes, 2014
The envelope theorem is used to solve maximization problems in the fields of microeconomics and finance. It is a fundamental result in the calculus of variations and is therefore often used in large deviations research.

Automating Food Production: Evidence From the Dutch Food Industry

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Automation technology has the potential to replace a significant part of the labour force in the food industry. With data from 2002 to 2023, I investigate the causal treatment effects of the adoption of automation technology in the Dutch food industry. Automation technology in the food industry is used in a variety of tasks, such as logistics,

Poisson enveloping algebras and the Poincaré–Birkhoff–Witt theorem

open access: yesJournal of Algebra, 2017
Poisson algebras are, just like Lie algebras, particular cases of Lie-Rinehart algebras. The latter were introduced by Rinehart in his seminal 1963 paper, where he also introduces the notion of an enveloping algebra and proves --- under some mild conditions --- that the enveloping algebra of a Lie-Rinehart algebra satisfies a Poincaré-Birkhoff-Witt ...

Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

Accounting for the Evolution of China's Production and Trade Patterns

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We study the evolution of China's production and trade patterns during its integration into the global economy. Using firm‐level microdata, we document how production and exports shifted across industries and within industries across firms.

Cross‐Prudence and Optimal Prevention

open access: yesInternational Economic Review, EarlyView.
ABSTRACT In this paper, we study optimal prevention in the presence of a correlated nonfinancial background risk. Under positive correlation, cross‐prudence in the nonfinancial attribute reduces optimal prevention. We establish this result in the most direct extension of the standard prevention problem with binary marginal distributions and show that ...

Conceptualising post‐growth to advance corporate sustainability research: A comparative literature review

open access: yesInternational Journal of Management Reviews, EarlyView.
Abstract This comparative literature review explores how an expanding body of interdisciplinary post‐growth literature aligns, extends or challenges ecocentric Corporate Sustainability (eCS) research in management (i.e., rooted in systems thinking, emphasising planetary boundaries, ecological limits and embeddedness).
