We use data for 20 manufacturing sectors at the 3-digit SIC level. This study also provides the first comprehensive examination of sources of growth, which allows one to decompose total factor productivity growth, separating out technical efficiency changes from technological progress. We find that ...

For both the two finite difference goedesic model schemes we set [Math Processing Error]μ=1 and [Math Processing Error]ν=0.25, while [Math Processing Error]ϵ=0.05 for the second order model. Further, ’GMFD 1ord’ exploits the linear CFL condition [Math Processing Error]Δt=λΔx, ...

Let mu(M,D) be the self-affine measure generated by an expanding integer matrix M is an element of M-2(Z) and an integer three-element digit set D = {(0, 0)(T), (alpha, beta)(T), (gamma, eta)(T)}. In this paper, we show that if 3 vertical bar det(M) and 3 (sic)...
Land use metrics were developed from a number of sources and examine land use parameters for more than 10,000 sites in more than 1O0 four-digit SIC classes within North America. The new metrics focus on revenue generated per land area, jobs created per land area and toxic and hazardous ...
