A violation of monotonicity in a noncooperative setting

Montero, Maria; Vidal-Puga, Juan - 2012

A power measure is monotone if a player with a larger weight is assigned at least as much power as a player with a smaller weight in the same weighted majority game. Failure of a power index to satisfy monotonicity is often considered a pathological feature. In this paper, we show that...

A, B, C’s, (and D’s) for understanding VARs

Fernández-Villaverde, Jesús; Rubio-Ramírez, Juan … - 2005

The dynamics of a linear (or linearized) dynamic stochastic economic model can be expressed in terms of matrices (A, B, C, D) that define a state-space system. An associated state space system (A, K, C, S) determines a vector autoregression (VAR) for observables available to an econometrician....
