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...

The conditional cash transfer program «Oportunidades» has been implemented in Mexico in order to alleviate intergenerational poverty by investing in human capital through education, health and nutrition. We estimate food and nutrient elasticities of demand with respect to income and price by...

The purpose of this paper is to assess the extent of asynchronicity in the authorisations of new genetically modified organism (GMO) events between importing and exporting countries. Based on the literature, we systemise the GMO regulatory framework and use dissimilarity and stringency indices...

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...

The objective of this paper is to present an evolution of PMP model suitable to estimate the revenue function and to provide price elasticity due to the variation of subsidies at farm level, especially if they are decoupled. This problem arises when individual data of farm households in a given...

This paper analyses relevant determinants for the probability to initiate a dispute on policy measures under the World Trade Organization (WTO) dispute settlement system. The empirical analysis differs from existing assessments by focusing on agri-food related disputes and provides a more...

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...

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...

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,...
