Revisiting the Party Paradox of Finance Capitalism: Evidence from Switzerland, Sweden and the Netherlands

The 'party paradox' thesis claims that centre-left parties have a genuine interest in pro-shareholder corporate governance reforms, while centre-right parties oppose such reforms. Based on case studies of Switzerland, Sweden, and the Netherlands, I test the accuracy of this thesis and find that it does not apply to either of these cases: in Switzerland pro-shareholder reforms were made possible by centre-right not centre-left support; In Sweden and the Netherlands pro-shareholder reforms were marginal, because a broad coalition uniting centre-right and centre-left opposed them. My findings show therefore that the 'party paradox' is not a universal phenomenon and that most micro-level explanations of this phenomenon are inaccurate. In order to explain in which cases a party paradox will emerge, we need to add the nature of relations between employees and employers (cooperative vs. confrontational) as a determinant of centre-left preferences.Corporate governance, legal reform, Switzerland, Sweden, the Netherlands

Lattice model of three-dimensional topological singlet superconductor with time-reversal symmetry

We study topological phases of time-reversal invariant singlet superconductors in three spatial dimensions. In these particle-hole symmetric systems the topological phases are characterized by an even-numbered winding number $\nu$. At a two-dimensional (2D) surface the topological properties of this quantum state manifest themselves through the presence of $\nu$ flavors of gapless Dirac fermion surface states, which are robust against localization from random impurities. We construct a tight-binding model on the diamond lattice that realizes a topologically nontrivial phase, in which the winding number takes the value $\nu =\pm 2$. Disorder corresponds to a (non-localizing) random SU(2) gauge potential for the surface Dirac fermions, leading to a power-law density of states $\rho(\epsilon) \sim \epsilon^{1/7}$. The bulk effective field theory is proposed to be the (3+1) dimensional SU(2) Yang-Mills theory with a theta-term at $\theta=\pi$.Comment: 5 pages, 3 figure

Irreducible compositions of degree two polynomials over finite fields have regular structure

Let $q$ be an odd prime power and $D$ be the set of monic irreducible polynomials in $\mathbb F_q[x]$ which can be written as a composition of monic degree two polynomials. In this paper we prove that $D$ has a natural regular structure by showing that there exists a finite automaton having $D$ as accepted language. Our method is constructive.Comment: To appear in The Quarterly Journal of Mathematic
