Stochastic impulse control with discounted and ergodic optimization criteria: A comparative study for the control of risky holdings [PDF]

We consider a single-asset investment fund that in the absence of transactions costs would hold a constant amount of wealth in the risky asset. In the presence of market frictions wealth is allowed to fluctuate within a control band: Its upper (lower ...

Semi‐automated assessment for NatureServe subnational conservation status ranks for state floras

Applications in Plant Sciences, EarlyView.
Abstract Premise Conservation status ranks measure the potential risk of extinction for species at global, national, and subnational levels, taking into account rarity, threats, and trends. These assessments are largely incomplete due to funding and resource limitations.

Growth dynamics, skeletochronology, and histovariability of the theropod dinosaur Berthasaura leopoldinae

The Anatomical Record, EarlyView.
Osteohistological sampling on different bones of theropod dinosaur documents discrepant age record, growth, and metabolism. This could result unprecise paleobiological inferences if samplings are based on single bones. However, multi‐bone sampling can attenuate these discrepancies, helping to infer growth dynamics and physiology of these extinct ...

Optimal Time to Sell in Real Estate Portfolio Management [PDF]

This paper examines the properties of optimal times to sell a diversified real estate portfolio. The portfolio value is supposed to be the sum of the discounted free cash flows and the discounted terminal value (the discounted selling price).

Coverage generosity of novel anti‐rheumatic drugs in Medicare Advantage and stand‐alone Part D plans

Arthritis &Rheumatology, Accepted Article.
Objective To examine coverage of self‐administered disease‐modifying anti‐rheumatic drugs (DMARDs) in Medicare Part D. Methods Using 2022‐2026 Part D formulary data, we assessed coverage of the following DMARD classes that treat relapsed rheumatoid arthritis (RA): tumor necrosis factor (TNF) inhibitors, T‐cell co‐stimulatory modulator, Interleukin‐6 ...

Bounding Rationality by Discounting Time [PDF]

, 2009
Consider a game where Alice generates an integer and Bob wins if he can factor that integer. Traditional game theory tells us that Bob will always win this game even though in practice Alice will win given our usual assumptions about the hardness of ...

Avoiding Extinction: Equal Treatment of the Present and the Future [PDF]

Equal treatment for the present and the future was required in two axioms introduced in Chichilnisky [12] [15]. We provide a characterization of the decision criterion that satisfy the axioms and show that the two axioms are equivalent to physical limits

Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Cost-utility analysis of interferon beta-1a (Avonex and Cinnovex) for relapsing remitting multiple sclerosis

Journal of Pharmacoeconomics and Pharmaceutical Management, 2018
Background: Cinnovex is a biosimilar form of intramuscular (IM) interferon beta-1a (IFNβ-1a) manufactured in Iran for management of multiple sclerosis (MS). The present study aimed to determine the cost-utility of Cinnovex versus Avonex for patients with
