A group of scholars, mainly from Europe, has done extensive research on the subject of "agency" (Pollitt and Talbot 2004; Pollitt et al. 2004; Pollitt 2006; Bowornwathana 2005).
Another group of scholars, more global in membership, does comparative work on politics and politician-bureaucrat relations with regard to administrative reform (Aberbach, Putnamn, and Rockman 1981; Farazmand 1997; Peters and Pierre 2001; Bowornwathana and Poochareon 2006).
Corruption is a unifying theme that draws comparative research (Rose-Ackerman 1999; Quah 1999).
