Topics • 3 ways of constructing aggregate GDP from industry accounts • the role of IT-producing, IT-using and non-IT industries in U.S. productivity growth 1995-2000 vs. 2000-2005 • the contribution of labor input in the productivity revival Information Technology and the American Growth Resurgence Jorgenson, Ho and Stiroh (2005) Industry Origins of the American Productivity Resurgence, Jorgenson, Ho, Samuels and Stiroh (2007), Economic Systems Research
Industry gross output production function: Value added of industry j: j=1,…85 using the SIC
3 ways of describing aggregate GDP • aggregate production function • GDP = V1 + … + Vn = f(K,L,Tagg) • -aggregate ppf • GDP = Vppf(V1, … ,Vn) = f(K,L,Tppf) • -Domar-aggregation over industries • GDP = Vppf(V1,V2,…,Vn) • = f(K1,…Kn,L1,…Ln,T1,…Tn)
Aggregate GDP from Production Possibility Frontier; translog index of industry value added: Focus on 3 industry groups:
Comparing aggregate production function GDP = V1 + … + Vn = f(K,L,Tagg) aggregate ppf GDP = Vppf(V1, … ,Vn) = f(K,L,Tppf)
Domar aggregation over industries. Aggregate TFP growth is the sum of industry TFP growth and reallocation of capital and labor.
Sources of Growth GDP = Vppf(V1, … ,Vn) = f(K,L,Tppf) GDP = f(KIT, KnonIT, LCollege, LnonCol,Tppf)
