Technical change at the farm level or changes in input prices often entail that the firm's supply function changes. These changes can take place in numerous ways. This paper presents a methodology that increases the consistency in supply responses across various sets of agricultural products and...

In this contribution we first present a methodology for integrated assessment of agricultural systems (SEAMLESS Integrated Framework), illustrate its application in an integrated assessment of high commodity prices and then discuss its flexibility and limitations. From there we take a broader...

Ongoing bilateral trade negotiations between the Mercosur group and the EU since 2000 on agricultural products served as incitement to analyse the impacts of possible outcomes. The objective of this paper is to quantitatively assess impacts of bilateral liberalisation scenarios on EU25 and...

General economic developments as well as recent fundamental changes in the Common Agricultural Policy will likely impact significantly on the European farm structure. Although a decline of total farm numbers continues to be the general observation, important differences occur across regions and...

This paper gives an overview on current and prospective modelling challenges for agricultural partial equilibrium (PE) models focussing on EU policies. Starting from a certain policy context, the paper highlights the current capabilities and limitations of existing PE models and, if available,...

Foreign direct investment (FDI) is known as a very relevant driver of economic growth and has found increased attention in recent trade research. Existing theories differ, however, in their conclusion regarding the relation between trade in goods and FDI: they appear to be either complements or...

The paper introduces a general methodological approach for the estimation of constrained optimisation models in agricultural supply analysis. It is based on optimality conditions of the desired programming model and shows a conceptual advantage compared to Positive Mathematical Programming in...

We formulate and estimate a farm level simulation model of agricultural crop production, and apply it to a scenario with increasing yield variability. The objective function is of the mean-variance utility type with a positive mathematical programming (PMP) cost function, and it is estimated...

Addressing competition in Germany’s dairy sector, this paper investigates imperfect competition on the raw milk market. By using the conjectural variation approach to determine dairy processors market power towards raw milk producers, regions in Germany with a high degree of imperfect...

We develop a Bayesian framework for estimating non-stationary Markov models in situations where macro population data is available only on the proportion of individuals residing in each state, but micro-level sample data is available on observed transitions between states. Posterior...
