The Limits of ‘Geopolitical Power Europe’: Why the EU's Eastern Neighbours Keep Hedging

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This article examines the hedging strategies pursued by the European Union's (EU's) eastern neighbours – Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine – and asks why hedging has remained a recurrent foreign‐policy response despite the EU's intensified geopolitical engagement after Russia's full‐scale invasion of Ukraine.

MONKES: a fast neoclassical code for the evaluation of monoenergetic transport coefficients in stellarator plasmas

Nuclear Fusion
MONKES is a new neoclassical code for the evaluation of monoenergetic transport coefficients in stellarators. By means of a convergence study and benchmarks with other codes, it is shown that MONKES is accurate and efficient.

Central Bank Digital Currency with Collateral‐Constrained Banks

Journal of Money, Credit and Banking, EarlyView.
Abstract We analyze risks to bank intermediation following the introduction of a central bank digital currency (CBDC) competing with commercial bank deposits as households' source of liquidity. We revisit the equivalence of payment systems result, introducing a collateral constraint on banks' borrowing from the central bank.

Optimization of stellarator configurations combining omnigenity and piecewise omnigenity

Nuclear Fusion
We present a method for optimizing stellarator configurations that combine omnigenity and piecewise omnigenity (pwO). Within the OOPS optimization framework (Liu et al 2025 https://arxiv.org/abs/2502.09350 ), we introduce a mapping technique that can ...

Beyond the Wind: Mapping Externalities and Their Role in Shaping Willingness To Pay for Wind Energy

Journal of Economic Surveys, EarlyView.
ABSTRACTWind power plays a central role in global low‐carbon energy transitions, offering significant environmental benefits through reduced greenhouse gas emissions and decreased reliance on fossil fuels. Yet, local opposition to wind projects persists, often driven by perceived externalities affecting communities and landscapes. This study conducts a

Reduced electrostatic turbulence in the quasi-isodynamic stellarator configuration CIEMAT-QI4

Nuclear Fusion
CIEMAT-QI4 is a quasi-isodynamic stellarator configuration that simultaneously features very good fast-ion confinement in a broad range of β values, low neoclassical transport and bootstrap current, and ideal magnetohydrodynamic stability up to $\beta ...

Aggregate Market Power: Measurement, Drivers, and Macroeconomic Effects

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey reviews the macroeconomic literature on market power, focusing on its measurement, determinants, and macroeconomic effects. It synthesizes evidence from concentration ratios, business dynamism indicators, and markup/markdown estimates, documenting a distinct change in trends since the 1980s, especially in the United States ...

Capital‐Labour Substitution in Macroeconomics: A Survey of Mechanisms, Dynamics and Policy Insights

Journal of Economic Surveys, EarlyView.
ABSTRACT Macroeconomic conclusions often hinge on a single, hard‐to‐pin‐down parameter: the elasticity of substitution between capital and labour, σ. This survey synthesises theory and evidence on how results change once we move beyond the Cobb–Douglas benchmark (σ=1$\sigma = 1$).

Assessment of validity of local neoclassical transport theory for studies of electric-field root-transitions in the W7-X stellarator

Nuclear Fusion
The neoclassical ambipolarity condition governing the radial electric field in stellarators can have several solutions, and sudden transitions (in radius) between these can then take place. The radial position and structure of such a transition cannot be
