Abelson's research has focused on public policy, foreign policy in both Canada and the United States. Think tanks are his specific area of interest.
Think tanks The influence and number of think tanks increased in the United States in Canada in the 1970s. The mandate of these nonprofit policy research organizations was to produce research and expert analysis to better inform those involved in making public policy. Abelson and others traced how think tanks came to resemble advocacy organizations by promoting ideological perspectives and prescriptive public policy options. In 2012, Abelson described this shift as the emergence of the "advocacy think tank".
The Washington Post cited Abelson, who had said that these new think tanks established in Washington, DC "tended to be less scholarly but increasingly political and are more likely to be tied to the fortunes of a party or a wing within a party". He has examined how
think tanks influence public policy and foreign policy in both the United States and Canada. ==Publications==
