Measuring Frame Evolution: Smoothed Temporal Framing Trajectories in Complex Policy Debates

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 5, Page 1688-1714, September 2026.
Abstract The European Union faces long‐term governance challenges in contested domains, such as migration management, health data sharing, and facial recognition technology. Across these fields, political debates are shaped by shifting ways in which actors frame problems and solutions. Understanding how such framing contests evolve over time is crucial

The Mixed Gamble of Competitive Dynamics in Family‐Controlled Firms

open access: yesJournal of Management Studies, Volume 63, Issue 6, Page 2509-2577, September 2026.
Abstract We extend the mixed gamble perspective to explain how family‐controlled firms frame and evaluate the difficult trade‐off between potential gains and losses in financial wealth (FW) and socioemotional wealth (SEW) when pursuing portfolio‐level strategic initiatives, as captured by competitive aggressiveness and complexity.

A Conditional Tail Expectation Type Risk Measure for Time Series

open access: yesJournal of Time Series Analysis, Volume 47, Issue 5, Page 967-983, September 2026.
ABSTRACT We consider the estimation of the conditional expectation 𝔼(Xh|X0>UX(1/p)), provided 𝔼|X0|<∞, at extreme levels, where (Xt)t∈ℤ$$ {\left({X}_t\right)}_{t\in \mathbb{Z}} $$ is a strictly stationary time series, UX$$ {U}_X $$ its tail quantile function, h$$ h $$ is a positive integer and p∈(0,1)$$ p\in \left(0,1\right) $$ is such that p→0$$ p\to ...

Testing for Unspecified Periodicities in Binary Time Series

open access: yesJournal of Time Series Analysis, Volume 47, Issue 5, Page 984-997, September 2026.
ABSTRACT Given random variables Y1,…,Yn$$ {Y}_1,\dots, {Y}_n $$ with Yi∈{0,1}$$ {Y}_i\in \left\{0,1\right\} $$ we test the hypothesis whether the underlying success probabilities pi$$ {p}_i $$ are constant or whether they are periodic with an unspecified period length of r≥2$$ r\ge 2 $$.

Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series

open access: yesJournal of Time Series Analysis, Volume 47, Issue 5, Page 998-1012, September 2026.
ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...
