    Dairy farms without quotas in Belgium: estimation and simulation with a flexible cost function (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: This paper evaluates the farm-level supply and income effects from removing milk quotas and reducing producer prices with increasing direct compensatory payments. Using a panel of Belgian dairy farms, we first estimate a multi-output multi-input flexible cost function that generates a U-shaped marginal cost curve for each farm of the sample. We then embed each farm cost function in a profit-maximisation programming model that is built and calibrated for each farm in the sample. Accounting for farm heterogeneity, the simulations show how dairy farms without quotas may respond differently to changes in prices and structural changes that may take place within the dairy sector. A quota removal with a 20 per cent reduction in milk prices keeps aggregate milk supply and farm income at about the same level of the 2006 reference year.

    How has the EU milk quota affected patterns of herd-size change? (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: This paper analyses the impact of milk quotas on the size structure of dairy herds in two major EU milk-producing member states, Germany and the Netherlands, using Markov chain models. Four mobility indicators characterising structural change are developed and calculated. Structural change in the dairy sector as measured by the mobility measures is found to be affected by the milk quota scheme. In the quota period, mobility out of dairying is lower, but the overall and upward mobility increase. This effect is stronger in the Netherlands than in West Germany.

    Modelling pig sector dynamic adjustment to livestock epidemics with stochastic-duration trade disruptions (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: We use a stochastic dynamic programming model to simulate the market implications of alternative foot and mouth disease scenarios in the Finnish pig sector. The model considers the dynamics of animal stock adjustment and price movements when the duration of export disruptions is unknown. Explicit treatment of these issues is crucial in the economic analysis of livestock epidemics, especially if there is a risk of a prolonged export ban. Results suggest that the risk of a prolonged ban increases disease losses considerably. It also increases economic benefits from production adjustments.

    Is embedding entailed in consumer valuation of food safety characteristics? (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: Consumers' preferences for food safety characteristics are investigated with a particular focus on the existence of an embedding effect. Embedding exists if consumer valuation of food safety is insensitive to scope. We conduct between-attribute external tests for embedding in two choice experiments concerning the value of food safety attributes in minced pork and chicken breasts. We find no evidence of embedding neither when using food safety attributes that are not close substitutes and which exhibit both private and public good characteristics, nor when using food safety attributes that are closer substitutes and which have primarily private good characteristics.

    Using graphical probability analysis (Bayes Nets) to evaluate a conditional DNA inclusion (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: This paper discusses the analysis of cases in which the inclusion or exclusion of a particular suspect, as a possible contributor to a DNA mixture, depends on the value of a variable (the number of contributors) that cannot be determined with certainty. It offers alternative ways to deal with such cases, including sensitivity analysis and object-oriented Bayesian networks, that separate uncertainty about the inclusion of the suspect from uncertainty about other variables. The paper presents a case study in which the value of DNA evidence varies radically depending on the number of contributors to a DNA mixture: if there are two contributors, the suspect is excluded; if there are three or more, the suspect is included; but the number of contributors cannot be determined with certainty. It shows how an object-oriented Bayesian network can accommodate and integrate varying perspectives on the unknown variable and how it can reduce the potential for bias by directing attention to relevant considerations and distinguishing different sources of uncertainty. It also discusses the challenge of presenting such evidence to lay audiences.

    Balancing rights and values in the Italian Courts: a statistical and conceptual analysis (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: The concept of balancing is of central importance in the assessment of legislative choices and in constitutional review. In conformity with the global tendency, balancing is increasingly used in judicial practice as an argumentation technique for solving legal disputes; more and more, judges of all levels ground their decisions on the balancing of individual rights, interests, principles, needs, and values. Legal science has formulated theoretical and formal models to explain the argumentation structure of balancing and the criteria governing the argumentation process, but, in the absence of a conceptual model that encompasses all elements in play and enables a comparative mechanism to be abstracted, mapping instances of judicial practice to abstract theories is still difficult. In this context, the objective of the project described here is to allow the logic of judicial practice emerge from cases, verifying from the bottom up the assumptions of theoretical models. Starting off from a broad analysis of Italian cases, the paper aims at analysing the object of this operation, i.e. what is `balanced' and what is the nature of this process. The research was conducted by analysing the so-called `massime' (case law abstracts) of the Italian High Courts (Constitutional Court, Supreme Court, Council of State) of the administrative courts (Regional Administrative Tribunals) and of a selection of lower court decisions. The methodology is divided into an initial phase of documentary collection and storage, a second phase of conceptual modelling and a third phase of data analysis.

    Agricultural policy in an uncertain world (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: This paper briefly reviews the current food situation and provides some historical perspectives on its evolution over time. It documents the important effects of agricultural productivity. It also evaluates the role of externalities, uncertainty and policy in the agricultural sector. The analysis stresses the joint role of uncertainty and externalities in the analysis of efficiency issues in the agricultural sector. Implications for farm management and agricultural policy are discussed.

    Looking into the future of agriculture in a changing climate (2011)
    Oxford University Press
    Details
    Publication Date: 2011-11-24
    Description: Looking into the future of agriculture raises three challenging questions: How can agriculture deal with an uncertain future? How do local vulnerabilities and global disparities respond to this uncertain future? How should we prioritise adaptation to overcome the resulting future risks? This paper analyses the broad question of how climate change science may provide some insights into these issues. The data provided for the analysis are the product of our new research on global impacts of climate change in agriculture. The questions are analysed across world regions to provide some thoughts on policy development.
