Measure‐valued processes for energy markets

open access: yesMathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Epistocracy and the Commitment Problem

open access: yesPhilosophy &Public Affairs, EarlyView.
ABSTRACT The epistocracy debate has turned largely on the character of the electorate—what voters know, whether competence filters can be designed well, and what filtered selection produces. Another strand has focused on the legitimacy of epistocratic justifications. I ask instead about the equilibrium effects of the institution.

The edible brown alga Sargassum fusiforme (Fucales) at the southern distributional limit in mainland Japan has declined on coasts facing the open ocean, showing reduced size and density

open access: yesPhycological Research, EarlyView.
SUMMARY The status of the edible brown alga Sargassum fusiforme (Fucales) in Kagoshima in 2025, located at the southern distributional limit in Kyushu, mainland Japan, was investigated to assess whether its populations were stable or declining, based on comparisons with herbarium specimens and records from previous studies conducted between the 1960s ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...
