Engines of Growth in the U.S. Economy

There is good reason to believe that R&D influences on TFP growth in other sectors are indirect.For R&D to spill over, it must first be successful in the home sector.Indeed, observed spillovers conform better to TFP growth than to R&D in the upstream sectors.Sectoral TFP growth rates are thus interrelated.Solving the intersectoral TFP equation resolves overall TFP growth into sources of growth.The solution essentially eliminates the spillovers and amounts to a novel decomposition of TFP growth.The top 10 sectors are designated engines of growt led by computers and office machinery.The results are contrasted to the standard, Domar decomposition of TFP growth.Spillovers;input-output;sources of growth

Outsourcing of Services and the Productivity Recovery in U.S. Manufacturing in the 1980s and 1990s

Manufacturing productivity growth recovered during the 1980s and 1990s, while other sectors, particularly services, did not. In the same period U.S. manufacturing has engaged in the "outsourcing" or "contracting-out" of service functions. Has the recovery of manufacturing been accomplished by industrial reorganization - sloughing off sluggish services - rather than technical progress? We analyze this question by reducing service inputs to their constituent elements of material inputs. Service productivity growth is thus imputed to the goods sectors, reducing the recovery of manufacturing productivity growth in the 1980s by one fifth. The recovery lasted through the 1990s, when high productivity performers in manufacturing have been relatively successful at outsourcing sluggish services.Measurement of Economic Growth;Aggregate Productivity

Universality in the Gross-Neveu model

We consider universal finite size effects in the large-N limit of the continuum Gross-Neveu model as well as in its discretized versions with Wilson and with staggered fermions. After extrapolation to zero lattice spacing the lattice results are compared to the continuum values.Comment: Lattice2004(theory

X-Ray Eclipse Timing in the LMXB EXO0748-676

Orbital period changes are an important diagnostic for understanding low mass X-ray binary (LMXB) accretion-induced angular momentum exchange and overall system evolution. We present our most recent results for the eclipse timing of the LMXB EXO0748-676. Since its discovery in 1985 it has apparently undergone three distinct orbital period "epochs", each characterized by a different orbital period than the previous epoch. We outline the orbital period behavior for EXO0748-676 over the past 18 years and discuss the implications of this behavior in light of current theoretical ideas for LMXB evolution.Comment: 4 Pages, 3 Figures, Submitted to the X-Ray Timing 2003: Rossi and Beyond conference, November 200
