A Splitting Architecture for Exact Reduced Coulomb Friction

Computer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

When do proxy advisors improve corporate decisions?

Economic Inquiry, EarlyView.
Abstract This paper studies the impact of proxy advisors on shareholder decision‐making. We posit two assumptions: (i) the board is at least as well informed as any individual shareholder; (ii) shareholders can condition their information acquisition on the proxy advisor's (PA) recommendation.

Ethnic Groups' Access to State Power and Group Size

Economics &Politics, EarlyView.
ABSTRACT Ethnic‐based political inequality is widespread, yet its underlying drivers remain poorly understood. This paper shows that an ethnic group's relative size is a key correlate of its access to central executive power. Using data on 575 groups across 181 countries from 1946 to 2021, and restricting attention to non‐dominant groups, I document a ...

Innovation and the great divergence

The Economic History Review, EarlyView.
Abstract Recent historical national accounting data show that the timing of the Great Divergence hinges on the different trends in north‐west Europe and the Yangzi Delta region of China. Although north‐west Europe only pulled ahead of the Yangzi Delta after 1700, both the positive trend of GDP per capita in north‐west Europe after 1700 and the negative
