The economic analysis of regulation is a broad topic, with implications for environmental protection, communications and technology policy, public health, immigration, national security, and other areas affecting risk and welfare in society. This chapter covers only a portion of the relevant ground, focusing on the following essential topics: First, what do we mean by “economic analysis” and what do we mean by “regulation”? Second, why has this topic become an important one, not only the United States, but in most advanced democracies? Third, why is economic analysis and regulation a contested, even contentious, aspect of modern regulatory activity? Finally, and most important, how is economic analysis structured into regulatory decision-making, and how might existing arrangements evolve over time?

Market Situation

A project of a new milk drying unit processing 4800 kg/h of fresh milk into milk powder with expected steam consumption of 1000 kg/h (equivalent to ca. 2.6 GJ/h) was assessed. In this paper, investment profitability of this project was analyzed combining mathematical modeling, market analysis, and parametric sensitivity study. Aspen Plus was used as the simulation environment to determine values of key process variables—major streams, mass flows, and energy consumption. Co-digestion of cattle manure in an adjacent biogas plant was considered to provide biogas to partially or completely substitute natural gas as an energy source. As biogas composition from potential co-digestion was unknown, variable methane content from 45 to 60 mol.% was considered. In the next step, thorough economic analysis was conducted. Diverse effects of biogas addition depending on market prices, biogas treatment costs, and biogas methane content were simulated and evaluated. In a market situation closest to reality, biogas mixing to boiler fuel decreased simple payback period from 11.2 years to 5.1 years. However, if biogas treatment costs were high (final biogas price equal to or above 0.175 EUR/m3), the simple payback period was increased two- to sixfold, making the analyzed project practically unfeasible.

This paper uses both survey and anecdotal data of members of the Roxbury Biodynamic Farm, the second largest CSA in the United States, to present a theory of demand for CSA membership. Included in the discussion is consideration of the evidence that there is a direct relationship between production method and demand, usually a shibboleth in traditional economic analysis. Further exploration considers the possibility that over time participation influences the very nature of demand for CSA membership, and hypothesizes that this dynamic demand is a necessary but insufficient condition for the sustainability of CSA.</span></span></p>

Based on the nutrient uptake of the criolla potato (Solanum phureja var. Galeras), the critical nutritional levels were determined on a farm in the Carrizal district of the municipality of Granada (Cundinamarca). Five fertilizing treatments were used: 0 fertilization (control), commercial control (CC), proposed recommendation + 50% (PR + 50%), proposed recommendation (PR), proposed recommendation - 50% (PR - 50%); organized with a random complete block design with three repetitions and repeated measurements over time; in each one, the material and nutrient absorption were evaluated in four phonological stages; in which the harvest, yield and profitability were measured. It was observed that the dry material increased rapidly until 113 days after planting (dap) and was higher in treatments CC and PR + 50% with 8,818 and 7,743 kg ha-1 , respectively. The statistical analysis showed that the elements: N, P, K, Ca, Mg, S, Zn, Cu and B did not present significant differences over time after 77 dap in treatments CC and PR + 50%. There were no significant differences in yield for treatments CC and PR + 50% but there were significant differences between these treatments and the others. The economic analysis showed that treatment CC had the highest profitability, confirming this as the critical level for the Galeras variety in Granada (Cundinamarca).

In Bangladesh, traditional technologies like Dole, Auri, Bamboo Gola, Motka, and Plastic bag are widely used in rice storage. Hot and humid weather of the country favors the growth of insects in these which are not functional for rice storage. Recently, hermetic bag (HB) GrainPro and PICS bags are suggested for rice storage without being subjected to economic analysis in the country. Very few empirical studies on the economic analysis of storage technologies were conducted at laboratory and field conditions. In it, losses of rice storage using traditional technologies and HB were evaluated to judge the economic effects of these. Moreover, determinants of storage benefit were analyzed for different devices and econometric modeling was formulated to have the understanding the benefit of reduced loss by storage over time. These benefits were found to increase with time meaning that a farmer gained more benefit by storing longer period in HB. Results showed that economically feasible and attractive in investing these technologies at a discount rate of 12 percent by using financial analytical tools like net present value (NPV) and benefit-cost ratio (BCR) of different storage technologies. The results also indicate that gain of storage clearly increased over time. Considering BCR, Plastic drum use in rice storage is the most profitable storage technology followed by GrainPro and PICS Bag for consumption. Regression analysis of treatment and time effect of storage indicated that percentage profit per month is found the highest in GrainPro bag followed by PICS bag, Dole, Plastic bag and Motka, respectively. Promotion of PICS and GrainPro bags in rice seed storage would be more cost-effective and economically feasible to farmers.

Abstract Adobe is an old material used in construction but over time, this construction system has lost space and preference among population. Hence, the need to seek alternatives as professionals in the construction area to encourage the use of the Adobe technique has raised. Thus, the present study made a cost of the items involved in the construction of houses from the adobe based on the theoretical references. In addition, it established a unit price analysis that identifies the particularities of this system focusing on an analytical, descriptive-conclusive methodology whose data are analysed from the results of applying a survey (n = 96) to the inhabitants of the rural sector of Cuenca and construction experts (n = 11). The average price of the construction of houses with Adobe is $ 38,357.23 dollars for a house of 150 m2 taking into account that the real costs and the construction activity are sensitive to changes in the population and market prices.
