English to Russian Social Sciences Idioms / Maxims / Sayings the close case

Sensing that capital costs did not have the same impact on profitability as operating expenses, management in a close case might choose an owned over a leased facility, a flat rate that encouraged use of its facilities and hence required their expansion over a capital-conserving peak surcharge, a plant with heavy initial cost but light maintenance over a less expensive plant that would require greater outlays for maintenance over its lifetime, excessive backup or “fail safe” devices, zero queuing, and so on—many of these being practices dear to the engineer’s heart anyway.

Even assuming that the bias operates only in the close case, the cumulative inefficiencies traceable to it could be quite substantial.
