Capital productivity growth shows how a change in the volume of assets, such as buildings, machinery, computers and IT, and land, affect output growth. An increase in capital productivity means that a unit of capital is producing more output than in the previous year, or that the same amount of amount is being produced for fewer capital inputs.   1. Introduction. It is well known that during production processes, desirable, or good, outputs are frequently obtained alongside harmful by-products (what we call undesirable or bad outputs 2) such as water and air pollution which may lead to environmental traditional measures of productivity growth ignore undesirable outputs and this can lead to a biassed evaluation (Chung et .

A Madill yarding crane was monitored over a two-month period in in a coastal B.C. second-growth stand. Productivity, costs, and profitability were determined.

Although productivity and costs averaged m3 per productive machine hour and $/m3 respectively, marginal economics analysis showed % of J-grade logs, % of X. Productivity and Profitability of Grapple Yarding Bunched B.C. Coastal Second-Growth Timber: Author(s) or contact(s): A.J.

Two Madill yarding cranes were monitored over a 3-week period in in a stand, predominantly of Douglas fir [Pseudotsuga menziesii], where chokers were used for yarding mechanically felled and bunched second-growth timber.

Productivity, costs and profitability of the choker system were determined and compared with use of grapple systems on the same yarding by: 2.

New techniques have recently appeared that can extend the advantages of grapple yarding to fast-growing plantations. The most promising technique consists of an excavator-base un-guyed yarder equipped with new radio-controlled grapple carriages, fed by another excavator stationed on the cut-over.

This system is very productive, avoids in-stand traffic, and removes operators from positions of. PRODUCTIVITY, COSTS, AND OPTIMAL SPACING OF SKYLINE CORRIDORS OF TWO C A B L E YARDING SYSTEMS IN PARTIAL CUTTING OF SECOND-GROWTH FORESTS OF C O A S T A L BRITISH COLUMBIA by D A G RUTHERFORD, R.P.F.

Productivity in its simplest form is output per hour worked, and its recent. For an extraction distance of m, a lateral yarding distance of 43 m and a payload of m3 per turn, the yarding cycle time was estimated to about min.

The parables have been analyzed with previous reports and studies in the subjects. The results in the paper show that the case farm has maintained profitability in their growth in.

We commonly focus on labour productivity measured by output per person employed or output per person hour.; A better measure of productivity growth is total factor productivity which takes into account changes in the amount of capital to use and also changes in the size of the labour force.; If the size of the capital stock grows by 3% and the employed workforce expands by 2% and output (GDP.
