Multiple goals in farmers’ decision making: The case of sheep farming in Western Greece AgEcon
Sintori, Alexandra; Rozakis, Stelios; Tsiboukas, Kostas.
Management strategies and performance differ among farmers, as a result of different, multiple and often conflicting goals. Many approaches to building farm level models that incorporate multiple goals have been developed over the years, most of which share a common weakness. The determination of the goals to be used as attributes in the utility function is the result of a highly interactive process with the individual farmer, often difficult to implement. In this study, we use a non-interactive methodology, described in recent literature, to elicit the utility function of selected sheep farmers in western Greece, since farmers often appear reluctant to answer straightforward questions about their goals and preferences. Τhe results indicate that sheep...

Modeling Greenhouse Gas Emissions on Diversified Farms: The Case of Dairy Sheep Farming in Greece AgEcon
Sintori, Alexandra; Tsiboukas, Kostas.
Agricultural activity has been identified as a considerable source of Greenhouse Gas (GHG) emissions. Emissions from ruminant livestock farms are produced particularly due to CH4 emissions from enteric fermentation. Dairy sheep farming is the most important livestock production activity in Greece, characterized by a high degree of farm diversification. This paper addresses the issue of the evaluation of GHG emissions of Greek dairy sheep farms, through the use of a whole farm mathematical programming model that uses farm level data and optimizes total gross margin. Mathematical programming models are an appropriate tool, when addressing complex issues, such as GHG emissions. The analysis is undertaken on different farm types, instead of a representative...

Assessing economic incentives for dairy sheep farmers: A real options approach AgEcon
Tzouramani, Irene; Sintori, Alexandra; Liontakis, Angelos E.; Alexopoulos, George.
New policy measures have been introduced to transform Greece’s agriculture into a more modern and environmentally friendly agriculture. Adopting new technology and environmentally friendly production systems involves risk and uncertainty, which in turn stress the need for well designed policy schemes. This study attempts to examine the effects of income variability upon the decision to adopt new technology and environmentally friendly production systems by introducing the real options analysis to dairy sheep farming in Greece. The real options procedure revealed that the investment in new technology in dairy sheep farms under organic scheme is profitable. Attractive economic incentives that are offered by the applied agricultural policy to young farmers...

MODELLING ECONOMIC ALTERNATIVES FOR TOBACCO PRODUCERS: THE CASE OF SHEEP FARMING AgEcon
Tzouramani, Irene; Karanikolas, Pavlos; Alexopoulos, George; Sintori, Alexandra; Liontakis, Angelos E..
After the introduction of the new tobacco regime, many regions in Greece, formerly specialized in tobacco cultivation, are now facing serious threats of economic and social decline. Sheep farming is considered by many analysts as a viable alternative to tobacco. This study analyses the financial performance of sheep production and the risk that producers are taking. Through a stochastic efficiency analysis with respect to a function we explore the economic viability of conventional and organic sheep farming; key factors determining the economic outcome of these activities are also investigated. Both organic and conventional sheep farming appear as viable alternatives. The viability of organic farming lies, mainly, in organic payments. Conventional farming...

Policy implementations for organic agriculture: A real options approach AgEcon
Tzouramani, Irene; Liontakis, Angelos E.; Sintori, Alexandra; Alexopoulos, George.
Organic farming has experienced a vast increase within the EU, despite the fact that it implies greater risk and uncertainty than that of conventional farming. This is the result of the increased environmental concern and the rising demand for quality food, which led to the implementation of the organic policy scheme. Nevertheless, the production of organic fruits, including cherries, is still limited in the EU. Farmers will adopt this alternative farming system only if the support provided by the existing policy regime out weights the increased risk and uncertainty. This study explores the effectiveness of the current policy measures for the production of organic cherries in Greece, using the real options methodology. The framework of real options...

Assessing agricultural policy incentives for Greek organic agriculture: A Real options approach AgEcon
Tzouramani, Irene; Sintori, Alexandra; Liontakis, Angelos E.; Alexopoulos, George.
The adoption of organic agriculture or livestock involves risk and uncertainty, and to overcome this, well designed schemes are required. Are the current support measures attractive for farmers who wish to convert to organic? At first, this study tries to assess the optimal investment trigger for a new comer into organic dairy sheep farming system and secondly, to evaluate the investment profitability of an existing organic farmer in his attempt to improve his farm. Results indicate that the framework of real options analysis is an appropriate form of analysis if the question of investment profitability is examined under risk and uncertainty and the role of economic subsidies offered to organic farmers is assessed.
