Previous meta-analyses examined hypothetical bias studies with the aim of identifying characteristics of stated preference (SP) design that potentially reduce hypothetical bias. However, previous meta-analyses combined observations for both public and private goods in their models. In this paper, we argue that eliciting values for public and private goods should be considered in separate models. Individuals’ behaviours, the choice of mechanism and the efficiency of mitigation techniques are specific to each type of good.
Enjeux économiques du développement durable
Cet axe regroupe la recherche adressant la transition de nos économies vers une économie plus verte. De la réduction des gaz à effet de serre, l’électrification du transport, la gestion durable des ressources naturelles, l’impact environnemental des exploitations agricoles à la santé des animaux ne sont que des exemples des sujets de recherche couverts. La recherche se concentre sur les principaux acteurs économiques, à savoir les individus et les firmes, qui évoluent dans un environnement changeant.
A Bayesian non-neutral stochastic input distance function model is used to examine whether output specialization has an impact on the economic performance of vegetable producers in Benin. Specialization is assumed to have an effect on the production frontier itself, as well as on the distance of each producer's observed data to this frontier (technical efficiency). A derivative-based measure of economies of scope is obtained by exploiting the duality between the shadow cost and the input distance functions.
This study examines the relationship between market participation and agricultural tech- nology adoption. Using data collected in 2017 from 542 sorghum household farms in Mali, a triple hurdle model that integrates the three following separate stochastic deci- sions: improved sorghum varieties adoption, market participation and marketed quantity is proposed to investigate the underlying process of market participation. Results indicate that the adoption decision plays a key role in market participation and marketed quan- tities.
Analyzing production systems from a circular economy (CE) perspective helps pinpoint interventions to reduce the ecological footprint by reducing the use of resources, waste recovery, prolonged usage of products, recycling and reuse. Few studies exist on the measurement of the CE at the micro-level. Also, available metrics propose indicators that study only certain aspects of the CE’s socio-economic metabolism leaving other important components of the CE concept.
