The Oder (Szczecin) Lagoon in the southern Baltic Sea is a heavily eutrophicated and degraded coastal ecosystem. We applied a systems approach framework to critically evaluate whether existing water-management measures achieve water-quality objectives for the river and lagoon systems. Our simulations reveal that the existing water-quality objectives for the river and the coastal waters are not sufficiently complementary. We suggest new water-quality threshold concentrations, which are in agreement with the European Water Framework Directive, and we calculate acceptable maximum nutrient loads for the Oder River. These calculations suggest that external nutrient-load reductions in the river basin alone seem insufficient to achieve good water quality in the...

Parametric or Nonparametric Approaches to the Estimation of Marginal Cost in Dairy Production? A Comparison of Estimation Results
Provedor de dados: 31
Autores: Wieck,   Christine; Heckelei,   Thomas.
This paper compares various nonparametric models for the estimation of farm specific marginal costs function in the dairy sector. Specifically, locally weighted regression approaches using theory-consistent cost function frameworks as polynomials in the nonparametric approach are applied. A comparison of average marginal cost levels as well as marginal cost distributions across farms illustrates the different approaches.

Regional Distribution of Short-Run, Medium-Run and Long-Run Quota Rents Across EU-15 Milk Producers
Provedor de dados: 31
Autores: Moro,   Daniele; Nardella,   Michele; Sckokai,   Paolo.
This paper evaluates the distribution of short- and long-run marginal costs and quota rents across the EU-15 milk producers, by estimating a system of cost and input share equations on a panel data of dairy farms from 1996 to 2001. Regional and geographical location and the size of milk operations have been considered as the major factors affecting marginal costs. The results on quota rents highlights that Italian and Greek dairy farmers receive the highest economic rent (260 €/ton), while in Portugal the lowest (101 €/Kg) at least in the short-run. This is an indication that Italian and Greek milk supply would be the least 'sensitive' to a reduction in the intervention price. Several countries show negative long-run quota rents, indicating that in the...
