While some research finds that environmental regulation of hog production reduces output by small farms, other work finds that large farms downsize to avoid regulation. None consider the potential size-bias of regulation. We show theoretically that when size-based regulations are also size-biased, large farms downsize, expand, or do neither depending on how regulations shift their marginal prod...

This paper compares various nonparametric models for the estimation of farm specific marginal costs function in the dairy sector. Specifically, locally weighted regression approaches using theory-consistent cost function frameworks as polynomials in the nonparametric approach are applied. A comparison of average marginal cost levels as well as marginal cost distributions across farms illustrate...

this study investigates issues on efficiency and elasticity of broiler production in peninsular malaysia. data from 296 broiler farms were subjected to sfa, dea and bootstrap methods for technical efficiency; translog and tobit regression analyses to estimate elasticity of production and determinants of efficiency respectively in broiler production. we found that farmers produce mean efficiency...

this study carried out for economic investigation on laying hen farms in tehran province. the data was collected through completion of questionnaire by direct interview from 41 layer farms, which were selected by stratified random sampling method in 2013. among all types of production functions, the cobb-douglas production function was selected and its coefficients was estimated and average pro...

While wind farms have no inherent storage to supply power in calm conditions, this paper demonstrates that large tidal turbine farms in channels have short-term energy storage. This storage lies in the inertia of the oscillating flow and can be used to exceed the previously published upper limit for power production by currents in a tidal channel, while simultaneously maintaining stronger curre...

In face of gradual ecological deterioration, the Chinese government has been in search of more efficient and effective mitigation policies, aiming to promote the sustainability of livestock production. However, researchers and policy makers seem to neglect a key issue: pinpoint policies are the most important, which means niche targeting is the premise before any policy design, such that better...

The objective of this study was to estimate the prevalence and identify risk factors associated with the presence of Toxoplasma gondii in pig-fattening farms from Yucatan, Mexico. A cross-sectional study was conducted with a two-stage sampling. There were 429 pigs sampled from 39 farms randomly selected. Blood samples were collected to obtain DNA and serum. The presence of IgM and IgG antibodie...

The present study entitled ‘An Economic Analysis of Production Pearl Millet in Jaipur District Rajasthan’ was carried out 2022–2023 with a sample 120 participants. findings showed that Medium-sized farms had the highest percentage respondents graduate degree, followed by Small(62.31%) and Marginal(42.75%) farms, Medium-sized(54.23%) illiterate people. In marginal size average area per hectare h...
