This paper extends the cross sectionally augmented panel unit root test proposed byPesaran (2007) to the case of a multifactor error structure. The basic idea is to exploitinformation regarding the unobserved factors that are shared by other time series in additionto the variable under...

Since campaign finance reform is usually motivated by the concern that existing legislation can not effectively prevent campaign contributions to 'buy favors', this paper assumes that contributions influence political decisions. But, given that it is also widely recognized that interest groups...

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...
