Farm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in inves...

Rural farms are typically energy-intensive facilities with relatively low energy efficiency. In this sector, the introduction of renewable energies and integrated resource management technologies has been slower than in domestic industrial sector. The sources was an important step past, but they currently insufficient, as do not allow for adequate management. development new solutions control i...

in this paper, non parametric data envelopment analysis (dea) was subjected to the energy data of wheat producers in punjab state, india, and technical, pure technical and scale efficiencies were calculated for farms both category wise and zone wise. the main objective was to determine the strength of the correlation between non-parametric efficiencies and indices such as energy ratio and speci...

Transplantation of isolated germ cells from a fertile donor male into the seminiferous tubules of infertile recipients can result in donor-derived sperm production. Therefore, this system represents a major development in the study of spermatogenesis and a unique functional assay to determine the developmental potential and relative abundance of spermatogonial stem cells in a given population o...

This paper addresses the adequacy and perspectives of multi-agent system (MAS) models in the context of policy support for agricultural policy makers. The paper starts illustrating what MAS are and how they may be used. The general presentation is followed by the description of an exemplary spatial dynamic model of a large number of interacting farms (agents). This model is simulated for differ...

Hepatitis E virus (HEV) is a causative agent for hepatitis. HEV is transmitted via the fecal-oral route through contaminated drinking water and induces zoonotic infections through eating uncooked and undercooked meat of deer, wild boar, and swine. In Japan, genotypes 3 (G3) and 4 (G4) are prevalent in domestic swine. Here, we examined the genetic variation among HEVs derived from swine fecal sa...

INCE 1974, FOLLOWING PUBLICATION of Schuh’s “The Macroeconomics of Agriculture,” much research effort has been devoted to determining whether and how monetary policy affects the farm sector. One of the more active areas of interest has been the question of whether changes in the money stock affect the farm! nonfarm product relative price ratio. The reason for this particular interest, as descri...
