This paper deals with the detection of the non-invertibility in moving average (MA) models. We derive an inequality for MA processes. This inequality establishes bounds for the la-weighted sum of the autocorrelations of processes with positive real unit roots depending on the structure of the...

Uniform{price assignment games are introduced as those assignment mar- kets with the core reduced to a segment. In these games, for all active agents, competitive prices are uniform although products may be non-homogeneous. A characterization in terms of the assignment matrix is given. The only...
