The Theoretical Framework and Methodology to Estimate the Farm Labour and Other Factor-Derived Demand and Output Supply Systems. Factor Markets Working Document No. 44, May 2013

This paper provides a conceptual framework for the estimation of the farm labour and other factor-derived demand and output supply systems. In order to analyse the drivers of labour demand in agriculture and account for the impact of policies on those decisions, it is necessary to acknowledge the interaction between the different factor markets. For this purpose, we present a review of the theoretical background to primal and dual representations of production and some empirical literature that has made use of derived demand systems. The main focus of the empirical work is to study the effect of market distortions in one market, through inefficient pricing, on the demand for other inputs. Therefore, own-price and cross-price elasticities of demand become key variables in the analysis. The dual cost function is selected as the most appropriate approach, where input prices are assumed to be exogenous. A commonly employed specification – and one that is particularly convenient due to its flexible form – is the translog cost function. The analysis consists of estimating the system of cost-share equations, in order to obtain the derived demand functions for inputs. Thus, the elasticities of factor substitution can be used to examine the complementarity/substitutability between inputs.

Identity Construction in Europe: A Discursive Approach. IES WORKING PAPER 2/2010

Proposing a discursive approach to studying identity, this paper presents Positioning Theory as a theoretical framework for conceptualizing the construction of identity in discourse. The Positioning Diamond is employed to analyse the discourse surrounding the Danish Euro referendum. The analysis reveals how identities are constructed in discourse that promotes a ‘yes’ or ‘no’ vote in the referendum, highlighting the generally implicit allocation of rights and duties to actors within a specific narrative context. The penultimate section discusses appropriate criteria for evaluating discursive accounts, distinguishing between cases in which truth, normative and ethical criteria are applicable. Finally, the paper concludes with a discussion of policy considerations and recommendations.
