Combining discrete and continuous mixing approaches to accommodate heterogeneity in price sensitivities in environmental choice analysis AgEcon
Campbell, Danny; Doherty, Edel; Hynes, Stephen; van Rensburg, Tom M..
Data from a discrete choice experiment aimed at eliciting the demand for recreational walking trails on farmland in the Republic of Ireland is used to explore the consequences of misspecifying the cost coefficient. To enable straightforward calculation of WTP from the distributions of the non-price coefficients, the price coefficient is typically held constant in mixed logit models. This implies that all respondents are equally price sensitive. In this paper we test the validity of this assumption. Our approach is based on a comparison and combination of discrete and continuous mixing approaches (i.e., a mixture of distributions) to uncover the unobserved heterogeneity in price sensitivities. Results from the analysis highlight that model fit and...

The effect of using labelled alternatives in stated choice experiments: an exploration focusing on farmland walking trails in Ireland AgEcon
Doherty, Edel; Campbell, Danny; Hynes, Stephen; van Rensburg, Tom M..
Discrete choice experiment data aimed at eliciting the demand for recreational walking trails on farmland in Ireland is used to explore whether some respondents reach their choices solely on the basis of the alternative’s label. To investigate this type of processing strategy, the paper exploits a discrete mixtures approach which encompasses random parameters for the attributes. We find evidence that respondents employ different processing strategies for different alternatives and differences in processing emerge between rural and urban based respondents. Results highlight that model fit and policy conclusions are sensitive to assumptions related to processing strategies among respondents

Towards Measurement of Farm Sustainability - an Irish case study AgEcon
Dillon, Emma J.; Hennessy, Thia C.; Hynes, Stephen.
Sustainability Indicators (economic, environmental and social) are developed here using Irish National Farm Survey (FADN) data over a ten-year period (1996-2006) in an attempt to measure the sustainability of Irish agriculture at the farm-level. The general concept of sustainability is discussed and the development of agricultural sustainability indicators in an Irish context described. Individual indicators are dealt with in turn and the RERC SMILE (microsimulation) model is used to demonstrate how these indicators can be mapped at electoral division level. Economic viability was found to be generally in decline over the ten-year period examined, however, when individual farming systems were taken into account, some were found to perform better than...

The extent of farmer participation in the rural environment protection scheme – what habitats are actually being protected? AgEcon
Murphy, Geraldine; Hynes, Stephen; Murphy, Eithne; O'Donoghue, Cathal.
This paper modelled the participation decision of Irish farmers in an agri-environmental scheme. It also uses the sub sample of farmers in the National Farm Survey actively participating in the scheme in 2007 to model the various biodiversity options undertaken as a function of farmer demographic characteristics, farm characteristic and habitat variables. The results of the analysis demonstrate that younger, married farmers with larger farms are more likely to participate in REPS and that the voluntary aspect of REPS can mean that not all habitat types are equally likely to be covered by the scheme. Farmers with internationally important habitats on their farm, like intact peatlands or semi-natural grasslands are more likely to participate in REPS....
