The goal of this paper is to test whether changes in the marketing margin between the farm and the retail prices can result in an asymmetric relationship between the farm and the retail prices in the rice market of Taiwan. By separating the transaction cost variation into two regimes, this paper utilizes a two-regime TVECM with the error correction term serving as the threshold variable to crea...

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...

OBJECTIVE This qualitative study used a case study approach to explore the potential of farm-to-school programs to simultaneously improve children's diets and provide farmers with viable market opportunities. DESIGN Semistructured interviews were the primary data collection strategy. SETTING Seven farm-to-school programs in the Upper Midwest and Northeast regions of the United States. PAR...

Th e aim of the research was the comparison of economic feasibility of most common conventional and organic farm production in Slovenia. Th e methodology of an integrated deterministic technologic-economic simulation system KARSIM 1.0 (DSM) application for cost analysis and decision-making support on farms is described in this article. Th e direct simulation model result is an individual conven...

The dairy industry in northern Victoria faced dramatic changes between 2001/02 and 2002/03. Drought resulted in a substantial decrease in availability, and subsequent increase in price, of irrigation water and supplementary feed. Most farms recorded substantial net cash flow deficits. Prior to 2002/03, a project had been established using case studies and a spreadsheet model to examine potentia...

Climate change and energy security concerns have driven the development of policies that encourage bioenergy production. Meeting EU targets for the consumption of transport fuels from bioenergy by 2020 will require a large increase in the production of bioenergy feedstock. Initially an increase in 'first generation' biofuels was observed, however 'food competition' concerns have generated inter...

In some uniform price auctions, the auctioneer retains flexibility to adjust the total quantity sold after receiving the bids. Would such an auctioneer be better off committing to a fixed quantity and reserve price? Not necessarily. In the simplest possible model, this paper shows that auctioneer expected profit and social welfare are each strictly higher in all equilibria given adjustable supp...

Honduras has established itself as the leading producer of pond-raised shrimp in Central America. Although this activity already represents the third staple of the national economy, relatively few economic analyses have been conducted to date. For this study, data on production of farm-raised shrimp were collected from 21 farms. Data are from the year 1997. Information was collected on technica...
