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...

The empirical evidence currently available in the literature regarding the effects of a country's IMF program participation on its output growth is rather mixed. To shed new evidence on this issue, in this paper we specify a state- dependent panel data model accounting in particular for program...

This paper introduces the concepts of time-specific weak and strong cross section dependence. A double-indexed process is said to be cross sectionally weakly dependent at a given point in time, t, if its weighted average along the cross section dimension (N) converges to its expectation in...
