Turbulence-reduced high-performance scenarios in Wendelstein 7-X
Nuclear FusionIn the Wendelstein 7-X (W7-X) stellarator, turbulence is the dominant transport mechanism in most discharges. This leads to a ‘clamping’ of ion temperature over a wide range of heating power, predominantly flat density profiles where hollow profiles ...

Farmers' pro‐social motivations and willingness‐to‐accept in markets with public goods
American Journal of Agricultural Economics, EarlyView.Abstract To explain how some farmers' decisions may diverge from profit‐maximization, we incorporate proactive social preferences for public goods in an expected utility framework, in addition to reactive risk preferences to uncertainty. We offer empirical evidence that proactive preferences influence farmers' decisions alongside reactive preferences ...

Nuclear FusionMONKES 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.

Envisioning the Future of Work: From Ideas to Reforms
British Journal of Industrial Relations, EarlyView.ABSTRACT Two different theoretical perspectives concerning technology and the future of work are examined. One is linked to mainstream economics, whereas the other is associated with critical (‘post‐work’) discourse. Ideas about work—its nature and impacts on well‐being—matter in both perspectives.

Bulletin of Economic Research, EarlyView.ABSTRACT This paper examines how labor‐supply responsiveness, captured by the inverse Frisch elasticity, shapes wage inequality in the presence of directed technical change and automation. We develop a dynamic general equilibrium model with task‐based production, heterogeneous labor, and endogenous R&D.

Collision frequency dependence of polarization current in neoclassical tearing modes
, 2012 The neoclassical polarization current, generated when a magnetic island propagates through a tokamak plasma, is believed to influence the initial stage of the neoclassical tearing mode evolution.

Economic activity during extreme events
Canadian Journal of Economics/Revue canadienne d'économique, EarlyView.Abstract Although extreme weather events, natural disasters or infrastructure failures potentially have important economic effects, quantifying these effects over small areas and fine time intervals has been difficult because of the fairly coarse scales available in most data sources. This paper surveys the use of relatively new and finely grained data

Effect of Magnetic Axis Shift on Neoclassical Transport in Helical Torus [PDF]
, 2003 Neoclassical transport for large helical device (LHD) configurations is studied by solving the bounce-averaged Fokker-Planck equation. Numerical code employed in the present paper (CHD1) is much faster and more efficient than existing transport codes ...

The Heterogeneous Impact of Children on Maternal Employment: Evidence From East and West Germany
Economics of Transition and Institutional Change, EarlyView.ABSTRACT This study investigates the causal effect of fertility on female labour market outcomes in East and West Germany. We use twin births as an exogenous variation for family size. Our results suggest a negative relationship between the number of children and maternal labour market outcomes.
