R* with respect to n for the various cases examined. The following diagrams illustrate, schematically, the patterns of variation with respect to n.
(I) Straight-line depreciation, balanced stock, physical capital Case (I):
(The arrows show the influence of growth and financial capital on R*.) Case (2): .l
o n years
(Dotted arrows show the influence of changes in a-the greater is the value of a, the faster is the approach to 00. The function is not defined at l+r = a.) Case (4): This case cannot be shown in a general diagram because it depends on the ratio, min. Its value approaches that of (2) as m « n) --+ O. (II) Reducing-balance depreciation, balanced stock, physical capital Case (1):
80 THE ACCOUNTANT IN A GOLDEN AGE Cases (2) and (3) are similar to those for straight-line depreciation but, for n > 2, Rh < R*.
