Ethanol Plant Investment using Net Present Value and Real Options Analyses AgEcon
Schmit, Todd M.; Luo, Jianchuan; Tauer, Loren W..
A real option analysis of dry-grind corn ethanol plants compared to a standard net present value analysis (NPV) shows that the option values increase entry prices and lower exit prices of investment and disinvestment considerably. For a large plant, the gross margin of ethanol price over the corn price for a gallon of ethanol using NPV shows that entry will occur with a $0.45 margin and shutdown will occur at a $0.38. Under a real options framework, the margins for entry and exit become $1.33 and $0.13, respectively. Under baseline conditions, a large operating plant would become mothballed at $0.18 and reactivate if margins rebounded to $0.66. Growth in the variability of ethanol margins will delay new plant investments, as well as exits of currently...

Social Cost-Benefit Analysis of Scientific Versus Traditional Shrimp Farming: A Case Study from India AgEcon
Bhattacharya, Poulomi; Ninan, K.N..
This paper attempts a social cost-benefit analysis of scientific versus traditional shrimp farming in West Bengal, India. Using primary data, the paper shows that although intensive or scientific shrimp farming yields high returns as compared to traditional shrimp farming, when the opportunity costs and environmental costs of shrimp farming including disease risk are accounted for, scientific shrimp farming loses its advantage. In fact sensitivity analysis shows that if expected benefits were to fall short by 15% and costs rise by a similar proportion, scientific shrimp farmers report higher losses than traditional shrimp farmers. But large traditional shrimp farmers continue to report positive net returns. These results are also most pronounced for small...

The Economic Feasibility of Energy Sugar Beet Biofuel Production in Central North Dakota AgEcon
Maung, Thein A.; Gustafson, Cole R..
This study examines the financial feasibility of producing ethanol biofuel from sugar beets in central North Dakota. Under the Energy Independence and Security Act (EISA) of 2007, biofuel from sugar beets uniquely qualifies as an “advanced biofuel”. EISA mandates production of 15 billion gallons of advanced biofuels annually by 2022. A stochastic simulation financial model was calibrated with irrigated sugar beet data from central North Dakota to determine economic feasibility and risks of production for a 10MGY (million gallon per year) and 20MGY ethanol plant. Study results indicate that feedstock costs, which include sugar beets and beet molasses, account for more than 70% of total production expenses. The estimated breakeven ethanol price for the...
