A letter report issued by the Government Accountability Office with an abstract that begins "In 2008, GAO reported that 1,088 oil industry mergers occurred between 2000 and 2007. Given the potential for price effects, GAO recommended that the Federal Trade Commission (FTC), the agency with the authority to maintain petroleum industry competition, undertake more regular retrospective reviews of past petroleum industry mergers, and FTC said it would consider this recommendation. GAO was asked to conduct such a review of its own to determine how mergers and market concentration--a measure of the number and market shares of firms in a market--affected wholesale gasoline prices since 2000. GAO examined the effects of mergers and market concentration using an economic model that ruled out the effects of many other factors. GAO consulted with a number of experts and used both public and private data in developing the model. GAO tested the model under a variety of assumptions to address some of its limitations. GAO also interviewed petroleum market participants."

A letter report issued by the Government Accountability Office with an abstract that begins "To better assist veterans with service-connected disabilities seeking employment, in 2005, the Departments of Labor (Labor) and Veterans Affairs (VA) signed an agreement to coordinate employment services for disabled veterans. Around the same time, VA rolled out a redesigned employment program for these veterans, known as the Five-Track program, which also established an employment coordinator position and job resource labs. To help Congress understand the status of these initiatives, GAO was asked to provide information on (1) the progress in implementing the 2005 agreement and challenges to implementation, (2) the status of implementation of VA's Five-Track program and challenges posed by recently returning veterans, and (3) the role of employment coordinators and job resource labs in serving veterans. To obtain this information, GAO interviewed Labor and VA officials and national veterans' service organizations, and conducted site visits in five states."

A letter report issued by the Government Accountability Office with an abstract that begins "Since the 1970s, the roles of women as both students and athletes have changed in higher education, with female enrollment surpassing male enrollment, and female athletic participation showing gains as well. These changes have generated public interest in whether women participate in athletics at comparable levels to men and whether men's opportunities have decreased as a result of the increased opportunities for women. Under the Comptroller General's authority, GAO assessed the extent to which the numbers of men's and women's intercollegiate sports teams and participants at 4-year colleges have changed from the 1991-1992 through 2004-2005 school years."
