Equation (4.11) gives the following five Sefficiency definitions:
• iMacroSE = Inflow MacroSE S (ic = 1): the ratio of useful Macro-Outflow to
useful Macro-Inflow
• cMacroSE = Consumptive MacroSE S (ic = 0): the ratio of useful Consumption
to Macro-TUF s
• iMesoSE = Inflow MesoSE S (ic = 1): the ratio of useful Meso-Outflow to useful
Meso-Inflow
• cMesoSE = Consumptive MesoSE S (ic = 0): the ratio of useful Consumption to
Meso-TUF s
• iMicroSE = cMicroSE = MicroSE: the ratio of useful Consumption to useful
Micro-Inflow
Examples for the above terminologies:
• Macro-Outflow = ET + NR + VD + RP
• Meso-TUF = VA + OS + PP – (RF + RP)
• Micro-Inflow = Meso-Inflow = VA + OS + PP
Based on Eq. (4.9), the following beneficial 3ME equations can be written:
MacroS E b =
E T + N R + ic(V D + R P)
V U + O S + P P − (1 − ic)(V D + R P)

(4.12)
Equation (4.12) gives the following five bSefficiency definitions:
• iMacroSE b (ic = 1): the ratio of beneficial Macro-Outflow to beneficial MacroInflow
• cMacroSE b (ic = 0): the ratio of beneficial Consumption to Macro-TUF b
• iMesoSE b (ic = 1): the ratio of beneficial Meso-Outflow to beneficial Meso-Inflow
• cMesoSE b (ic = 0): the ratio of beneficial Consumption to Meso- TUF b
• MicroSE b : the ratio of beneficial Consumption to beneficial Micro-Inflow
Equation (4.11) and Eq. (4.12) give eight important indicators, namely, iMacroSE,
cMacroSE, iMesoSE, cMesoSE, iMacroSE b , cMacroSE b , iMesoSE b , cMesoSE b .
