The Provision of Ecosystem Services by Agriculture – a Spatially Explicit DEA Approach AgEcon
Kapfer, Martin; Hübner, Rico; Eckstein, Karin; Ziesel, Sigrid; Kantelhardt, Jochen.
According to the concept of ecosystem services, agriculture not only provides commodities but also cultural and regulating services. While it is easy to value commodity production by market prices, the valuation of cultural and regulating services is complex because of their public good character. Non-parametric approaches such as the Data Envelopment Analysis (DEA) allow for estimating the contribution of agriculture to such services. However, it is not enough to know the extent of ecosystem services provided; it is also necessary to be aware of which farmers provide these services and where they are provided. In this paper, we suggest a plot-specific approach combining GIS analysis and DEA models. This allows a spatially explicit assessment of...

A Microeconomic Model for Subsidies Allocation: the Case of Belarus AgEcon
Svetlov, Nikolai M.; Kazakevich, Iryna A..
The paper develops a microeconomic methodological framework that allows approaching subsidy allocation across the types of assets and impact of subsidies on agricultural outputs and profits. The methodology is based on a non-parametric production frontier estimation. The empirical application is made to 1084 Belarusian corporate farms. The results suggest targeting governmental support at grain and milk production. In this case, 4.14 trillion Belarusian roubles of subsidies increase the overall profit of the sample farms by 1.46 trillion. In the case of targeting, the farms with higher overall efficiency are more sensitive to the support and are able to absorb larger amount of subsidies. The opposite is true in the absence of targeting.
