Farmers’ acceptance of further strengthening of private certification systems AgEcon
Mondelaers, Koen; Garreyn, F.; Steurbaut, W.; Van Huylenbroeck, Guido.
In their continuous quest for ecologic improvements, private voluntary certification initiatives might undermine the willingness to continue of the participating farmers. In this research, the ecologic contribution and the farmers’ acceptance of changing the pesticide policy of a private certification initiative is presented. To measure the perceived farmers’ disutility, the choice preference technique is used. We can conclude that there is room for ecologic improvements but that farmers are in general change averse, primarily because of the fear that price compensation will remain largely absent.

Effect of changes in the institutional structure of irrigation water property rights on the willingness to pay of farmers for water: case of Tunisia AgEcon
Frija, Aymen; Chebil, Ali; Speelman, Stijn; Van Huylenbroeck, Guido.
This paper assesses the economic value of changes in the attributes of farmers’ irrigation water property rights in Tunisia. Changes on attributes generated by the transfer process of the property rights from the collective to the individual level in addition to changes in “constitutional” attributes were integrated into three scenarios. The valuation was conducted using the Contingent Valuation Method through the elicitation of individuals’ willingness to pay. Results show positive willingness to pay values for all scenarios. However, farmers of the studied region are shown willing to pay more for changes in the constitutional attributes. Furthermore their willingness to pay appears to be most affected by their perceptions concerning the organization and...

Modelling the effects of an abolition of the EU sugar quota on internal prices, production and imports AgEcon
Nolte, Stephan; Buysse, Jeroen; Van der Straeten, Bart; Claeys, Dakerlia; Lauwers, Ludwig H.; Van Huylenbroeck, Guido.
We apply a spatial price equilibrium model of the world sugar market to simulate an abolishment of the EU quota system in 2015/16. To overcome the normative nature of the approach, we calibrate the model by attaching a non-linear cost term to each trade flow. This is in some regards similar to positive mathematical programming. We suggest an economic interpretation and an econometric specification of the cost term. Production in the EU increases to almost 16 million tons. Twelve member states increase production, seven reduce it. Preferential imports are significantly reduced. Simulated effects are found to be more pronounced the higher the world market price.

Impact of the ‘Family-firm life cycle’ on the Management Processes Involved in Sustainable Glasshouse Horticulture AgEcon
Taragola, Nicole; Van Lierde, Dirk; Van Huylenbroeck, Guido.
In Flanders glasshouse vegetables and ornamental plants are typically produced at family businesses. At this type of businesses the objectives and long-term firm developments are influenced by the so called ‘family-firm life cycle’. In many cases the firm shows a life cycle that corresponds with the life cycle of the entrepreneur. The objective of the paper is to test the hypothesis that the ‘family-firm life cycle’ will have an impact on the personal and business characteristics, objectives and the quality of the management processes involved in sustainable glasshouse horticulture. As sustainable horticulture integrates the three P’s (People, Planet, Profit) special attention is paid to human resource, environmental and financial management. Data for the...

The sampling bias in multi-agent simulation models AgEcon
Buysse, Jeroen; Frija, Aymen; Van der Straeten, Bart; Nolte, Stephan; Lauwers, Ludwig H.; Claeys, Dakerlia; Van Huylenbroeck, Guido.
For practical considerations, it is in some case impossible to simulate MAS models at population level. The current paper shows that MAS models applied to samples with heterogeneous costs of interactions between agents have biased results. Heterogeneous costs of interactions in MAS models can come from the spatial dimension in MAS models or from fixed costs per interaction. The paper presents two correction procedures to remove the sampling bias and to increase the reliability of the outcome. The correction procedures can be very promising for future applications of MAS models because it becomes possible to deploy more complex models without bias on more detailed datasets that are only available at sample level, which will be the case for country- or...

Spatial Modelling of Water Availability and Choice of Crop Production in a River Basin AgEcon
Chellattan Veettil, Prakashan; Van Huylenbroeck, Guido.
This paper analyze the problems of water resource allocation and crop choice in a river basin using spatial analytical tools. Spatial variability of water availability is modelled by the product sum model. Here the water availability at any farm Z(xj) is a joint spatio-temporal environment and socioeconomic process. Water availability is estimated using spatial econometric tool. Here the spatial weight matrix (W) is constructed by taking water user associations (WUA) as boundaries. The choice of a crop is explained using spill over model in which the choice of a crop is influenced by the choice of neighbouring farmers. Here the spatial lag model is modified to adapt the latent variable (y*) which has a binary outcome.

Assessing the impact of the EU Common Agricultural Policy pillar II support using micro-economic data AgEcon
Buysse, Jeroen; Verspecht, Ann; Van Huylenbroeck, Guido.
The paper uses the case of Flemish investment support to make a quantitative analysis of pillar II support based on micro-economic data from the FADN and the administrative dataset of the investment support fund. A dynamic panel estimation quantifies the effect of support for settingup young farmers, structural investment support and support for investments on farm diversification, animal welfare or environmental investments.. The results show that investment support for farm diversification and structural support increase the total output and the income. Environmental investment support increase costs and decrease the farm income without a significant impact on output. The conclusion for the national debate is that the structural and the diversification...

EFFICIENCY ANALYSIS OF SMALL SCALE WOOL PRODUCTION IN THE FORMER TRANSKEI, SOUTH AFRICA AgEcon
Haese, M.D.; Calus, Mieke; Kirsten, Johann F.; Van Huylenbroeck, Guido; Bostyn, F..
Specialising in wool production could be a good opportunity for farmers in the former Transkei to upgrade to fully commercial and economic viable enterprises. This paper investigates the efficiency of the current practices of wool producers in three villages. Two of those villages are beneficiaries of the LandCare project of the National Department of Agriculture, and receive help on technical matters and marketing. The analysis shows that in the two villages beneficiary of the Land Care project the technical, allocative and economic efficiency of the wool production is higher than in the third village. In the latter, the technical efficiency of some of the farms is still good, but the difference is made in the marketing of the wool.

Diversification as a Survival Strategy for Marginal Farms an Exploratory Research AgEcon
Vernimmen, Tom; Bourgeois, Marie; Van Huylenbroeck, Guido; Meert, Henk; van Hecke, Etienne.
One of the common strategies in rural development programmes is to support the adoption of new on-farm activities. The rationale behind this is that farm diversification is a way to assure an appropriate level of income for the farmers. Through interviews with 49 relatively small farmers, the possibilities for diversification as a survival strategy are assessed. The analysis is mainly based on a classification of development pathways by Bowler (1992). Few forms of diversification appear to be successful as a survival strategy in case of economic problems. Only off-farm employment seems to be effective in this respect. The introduction of new activities on marginal farms is hampered by lack of financial and human capital. On the other hand, diversification...

Fertilization: trade-offs between manure abatement and plant productivity AgEcon
Van der Straeten, Bart; Buysse, Jeroen; Marchand, Fleur L.; Lauwers, Ludwig H.; Claeys, Dakerlia; Van Huylenbroeck, Guido.
In 2005, 30% of the Flemish farms faced a manure excess, while at aggregated level still 9.7% of the emission rights were unused. This means that, despite the various possibilities, Flemish farmers do not succeed in an effective exchange of manure between farms. In current paper is shown how inorganic fertilizer use influences the use and exchange of organic nitrogen. Because of the mutual interdependency between organic and inorganic nitrogen emission rights (or quota), inorganic nitrogen use limits the emission rights for organic nitrogen. Utilisation of these emission rights are analysed as a trade-offs choice between plant productivity (use of inorganic nitrogen) and manure disposal, as the major abatement alternative of manure production. Farmers...

Testing Asymmetric Price Transmission in the Vertical Supply Chain in De-regulated Rice Markets in Bangladesh AgEcon
Alam, Mohammad Jahangir; Begum, Ismat Ara; Buysse, Jeroen; McKenzie, Andrew M.; Wailes, Eric J.; Van Huylenbroeck, Guido.
Market liberalization at the domestic level and at the boarder level has been a dominant feature of market reforms in most developing countries including Bangladesh during the last two decades. A pre-requisite for producers and consumers to benefit from this new and changing market environment is the ability of market to function efficiently at their spatial or through the value chain dimensions which are very often constrained by different factors. The vertical integration of grain markets plays a crucial role in improving the welfare of the producers and the consumers. Therefore, the better the market integration, the lesser the intervention required by the government. There was a widely-held belief about the domestic markets in Bangladesh on possible...

Multifunctional Agriculture: How to Provide Incentives to Farmers? AgEcon
Van Huylenbroeck, Guido.
In this paper we anlyse the meaning of multifunctionality at farm level. After defining the concept, a number of examples are given to illustrate problems in delivery of non-commodity outputs. Based on a general micro-economic model, it is shown that farmers' behavior will depend on personal characteristics as well as on relative prices. Next, Instruments to give incentives to farmers to engage in the delivery of non-commodity outputs are discussed as well as the possibility of collective action. The paper ends with some conclusions and recommendations for further research and discussion.
