Aggregation in large dynamic panels
Pesaran, Mohammad Hashem; Chudik, Alexander - 2011
This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

Infinite dimensional VARs and factor models
Chudik, Alexander; Pesaran, Mohammad Hashem - 2007
dynamic systems. Restrictions on the coefficients of an unrestricted VAR are proposed that are binding only in a limit as the … number of endogenous variables tends to infinity. It is shown that under such restrictions, an infinite-dimensional VAR (or … IVAR) can be arbitrarily well characterized by a large number of finite-dimensional models in the spirit of the global VAR …
