Krasovskii’s Passivity

open access: yesIFAC-PapersOnLine, 2019
In this paper we introduce a new notion of passivity which we call Krasovskii's passivity and provide a sufficient condition for a system to be Krasovskii's passive. Based on this condition, we investigate classes of port-Hamiltonian and gradient systems which are Krasovskii's passive.

Passive investors, not passive owners

open access: yesJournal of Financial Economics, 2014
Passive institutional investors are an increasingly important component of U.S. stock ownership. To examine whether and by which mechanisms passive investors influence firms' governance, we exploit variation in ownership by passive mutual funds associated with stock assignments to the Russell 1000 and 2000 indexes.
