[ES] Los acuerdos internacionales negociados bajo la Convención Marco de las Naciones Unidas sobre el Cambio Climático no han modificado la tendencia al alza de las emisiones de gases de efecto invernadero. Desde la economía ecológica crítica, este artículo busca estimular el debate sobre si la actual Agenda Climática Global (ACG) está siendo eficaz o, por el contrario, necesita un giro de 180 grados, como sugieren investigadoras e investigadores críticos sobre política y gobernanza climáticas, que señalan a una ACG que alimenta el capitalismo como la causa de su fracaso. En otras palabras, estas autoras y autores sostienen que las reglas que rigen la economía capitalista mundial también están moldeando la ACG. Estas reglas se fundamentan en el imperativo del crecimiento económico que beneficia a una élite minoritaria al tiempo que estimula un metabolismo socioeconómico en constante expansión, responsable de la crisis socioecológica planetaria. El artículo subraya el cambio ocurrido en los principios rectores de la política climática a partir de la década de 1980, cuando el crecimiento se convirtió en un objetivo político global incuestionable en la esfera de la gobernanza internacional. En un contexto de emergencia climática donde la evidencia muestra una correlación positiva entre el PIB mundial y las emisiones, analizar críticamente la ACG dado su empeño en promover una economía verde pro-crecimiento bajo el paraguas del desarrollo sostenible se convierte hoy en una tarea ineludible., [EN] International agreements negotiated under the UN Framework Convention on Climate Change have not changed greenhouse gas emission trends. From a critical ecological economics perspective, this article pursues to further stimulate the debate on whether the current Global Climate Agenda (GCA) is being effective or, in contrast, needs a U-turn, as suggested by researchers on climate policy and governance who critically point to a GCA fueling capitalism as the cause behind its failure. In other words, these authors argue that the rules driving the world capitalist economy are also shaping the GCA. Such rules build on the growth imperative benefitting an elite minority while entailing an ever-expanding socioeconomic metabolism being responsible for the planetary socioecological crisis. The paper underlines the occurrence of a shift in the guiding principles of climate politics from the 1980s onwards when economic growth became an unquestionable global political objective at the international governance level. In a context of climate emergency where evidence shows a positive correlation between global GDP and emissions, critically analyzing the GCA due to its promotion of a growth-oriented green economy under the umbrella of sustainable development (SD) becomes an unavoidable task.

A range of empirical approaches to representing preference heterogeneity have emerged in choice modelling. Researchers have been able to explore the differences which selection of a particular approach makes to welfare measures in a particular dataset, and indeed have been able to implement a number of tests for which approach best fits a particular set of data. However, the question as to the degree of error in welfare estimation from an inappropriate choice of empirical approach has not been addressed. In this paper, we use Monte Carlo analysis to address this question. Given the high popularity of both the random parameter logit (RPL) and latent class models among choice modellers, we examine the errors in welfare estimates from using the incorrect model to account for taste preference heterogeneity. Our main finding is that using an RPL specification with log-normally distributed preferences seems the best bet.

Despite the vital role of utility functional form in welfare measurement, the implications of working with incorrect utility specifications have not been examined in the choice experiments (CE) literature. This paper addresses the importance of the specification of both non-monetary attributes and the marginal utility of income. Monte Carlo experiments have been conducted wherein different attribute specifications and assumptions for the Cost parameter –that is, different functional forms of utility– have been assumed to generate simulated choices on which Multi-Nomial Logit and Mixed Logit models have been estimated under correct and incorrect assumptions about the true, underlying utility function. The inferred values have been compared with the true ones directly calculated from the true utility specifications. Results show that working with simple experimental designs and continuous-linear specifications makes attribute specification irrelevant for measuring attribute marginal values regardless of the true effects the attribute has on utility.
