The second section provides the definition of a recession as well as the determination process for declaring a recession. It also provides information on the timing of all recessions since 1980. The third section summarizes the legislative history of federal extensions of unemployment benefits. It includes information on the permanently authorized extended benefit (EB) program as well as information on temporary unemployment benefit extensions. It also includes a brief discussion on the role of extended unemployment benefits as part of an economic stimulus package. The fourth section provides figures examining the timing of recessions and statistics that may be considered for determining extending unemployment benefits. The fifth section briefly discusses previous methods for financing these temporary programs. In particular it attempts to identify provisions in temporary extension legislation that may have led to increases in revenue or decreases in spending related to unemployment benefits.
