Effects of a flat rate introduction: shifts in farm activity and impact on farmers' income AgEcon
Marchand, Fleur L.; Buysse, Jeroen; Campens, V.; Claeys, Dakerlia; Fernagut, Bruno; Lauwers, Ludwig H.; Van der Straeten, Bart; Van Huylenbroeck, Guido.
Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land) compared to the current historical system (payments based on individual historic entitlements). Impact on production and income of arable, dairy and cattle farms of two different flat rate scenario's, is assessed with a farm-based sector model for Flanders. The model maximizes income at farm level, calibrated to observed farming behavior in 2001-2003. Farm data can be selected by farm type, size and region, simulations could be run for specific sub sectors, size...

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.

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...

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...

ESTIMATING THE EFFECT OF WATER CHARGE INTRODUCTION AT SMALL-SCALE IRRIGATION SCHEMES IN NORTH WEST PROVINCE, SOUTH AFRICA AgEcon
Speelman, Stijn; Buysse, Jeroen; Frija, Aymen; D'Haese, Marijke F.C.; D'Haese, Luc.
In South Africa water law has recently changed, adopting the principle of water as an economic good, thus levying charges on its use. For small-scale irrigators this is an important change, because currently their water use is entirely subsidized. In the coming years, subsidies will gradually decrease and an essential expected benefit of this policy change is that water use efficiency will rise, leading to reduced consumption and possible reallocation of the water saved. The exact impact of the water pricing policy on the irrigation water use or on the farmers' production system is however unclear. This study introduces a new methodology, based on data envelopment analysis, that allows estimating the effects on the agricultural production process and water...

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...
