Economic assessment of ethanol production in Bolivia, considering a scenario without expansion of ethanol production (SB1) and another scenario with expansion of production (SB2), until year 2030. Calculation of economic indicators: Net Present Value, net future value, Internal Rate of Return, Simple Payback Period, discounted payback period for both scenarios. A parametric sensitivity analysis considering variations every 10% (until reaching +30% and -30%) for certain variables and measuring the impact of such variations on the result of the net present value.
