Applying a bio-economic whole farm model we assess the impact of price and weather risk as well as different risk management strategies on the variability of the income in Swiss suckler cow production. We consider different on-farm risk management strategies such as the flexible adjustment of herd size, fodder composition and feed stocks, as well as an income insurance. Our results show that wi...

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

Decomposition methods suggest major contributors to variability in returns to New York dairy farms are purchased feed quantities and milk production; milk price variability contributes substantially less. Decomposing the Gini measure of income inequality indicates that milk revenues and purchased feed expenditures contribute most to farm return inequality over time.

From 1985 to 2002, most Federal conservation dollars going to farm operators have been to retire land from crop production. Yet most U.S. farmland (850 million acres) remains in active production. The Farm Security and Rural Investment (FSRI) Act of 2002 sharply increased conservation funding and earmarked most of the increase for working-land payment programs (WLPPs). The design and implementa...

Agriculture is important to New Zealand's economy. Like other primary producers, New Zealand strives to increase agricultural output while maintaining environmental integrity. Utilising modelling to explore the economic, environmental and land use impacts of policy is critical to understand the likely effects on the sector. Key deficiencies within existing land use and land cover change models ...

This paper tests whether structural change in US agriculture is an important channel to TFP growth and evaluates the relative impact of (i) public research and education policies, (ii) private R&D and market forces, and (iii) government farm programs on structural change. We specify a structural econometric model, fit it to US state aggregate data, 1953–1982, and use the associated reduced-form...

The present paper investigates how a storage unit, coupled with a wind farm could influence the economic operation of the power system. For this reason two optimization algorithms are implemented, where the storage capacity is assigned certain costs and is able to vary in size. The objective of the first optimization is to identify the optimal power infeed as well as the necessary battery capac...
