I saw your advert in the paper Vytorin Statin CBPP's projections lie above CBO's extended baseline scenario largely because they account for the lower revenues resulting from the American Taxpayer Relief Act that policymakers enacted in January to replace the so-called "fiscal cliff." They lie below CBO's alternative fiscal scenario because they assume policymakers will follow current laws and policies (which include the expiration of some tax cuts under ATRA) without making changes that constrain deficits further or, on the other hand, cutting taxes or expanding programs without offsetting the costs.
