A Universidade de Santiago de Compostela participou, coas universidades de Tennessee e Arkansas (EE UU) e o Instituto de Investigación de Economía Agrícola de Noruega, nun estudo sobre a relación entre a lectura do etiquetado nutricional e a obesidade do que se fai eco SINC. Os resultados indican que a diferenza entre as mulleres que len as etiquetas e quen non o fan é de cerca de catro quilogramos.
International Public Preferences and Provision of Public Goods: Assessment of Passive Use Values in Large Oil Spills
With global media reporting major environmental disasters, environmental damages linked to large oil spills may go well beyond the territorial limits of affected countries, particularly in the case of passive use values. In this analysis, we compare environmental damages linked a large oil spill off the coast of Spain using an online contingent valuation survey in three different European countries: Spain, UK, and Austria. Our results show that mean willingness to pay in Spain is about 124.37€/household, 80.87€/household in the UK, and 89.08€/household for Austria (expressed in 2009 prices). Conclusions and implications of our results suggest policy makers should consider the potential importance of passive use values in the compensation process of environmental damages caused by large international oil spills, especially within the European Union.
Assessing the impact of biodiversity on tourism flows: an econometric model for tourist behaviour with implications for conservation policy
This analysis provides an example of how biodiversity can be measured by means of different indicators, and how the latter can be used to assess the influence of the biodiversity profile of a region on the tourism flows towards it. Domestic Irish tourist flows have been chosen as a case study. Results show that most of the biodiversity and landscape indicators included in the analysis turn out to be statistically significant in determining tourists’ choices regarding the duration of their trip. As a result, policies pursuing biodiversity conservation appear to have a positive impact on the regional tourism.
The selection of an appropriate forest management program is an arduous task in which opinions and information are shared. In this research, we have tried to facilitate this process by applying the Best–Worst Scaling (BWS) method in order to discriminate among the various management alternatives and to identify the management preferences stated by a group of key actors in decision making process: common property forest owners. Descriptive results from the BWS method show the ranking for preventive wildfire policies from the best (most preferred) to the worst (least preferred) policy among those evaluated by forest owners. However, and after employing a Latent Class Model, we find that common forest owners can be classified into two different classes, especially distant in terms of preferences toward forest management priorities. On one hand, one of the classes (containing older individuals) is more likely to prefer policies based on direct economic incentives and quicker returns, whereas a second class (younger) prefers other policies that also contain environmental and social spillovers or benefits. Thus, we find that BWS may be a very suitable method of elicitation of preferences in the context of decision making under multiple conflicting criteria.
We use instrumental variable methods to investigate whether the impact of parental smoking habits on their children’s smoking decisions is a causal one. We find suggestive evidence of same-sex role models in two-parent households: mothers play a more crucial role in determining their daughters’ smoking decisions, whereas fathers’ smoking habits are primarily imitated by their sons. This same-sex parent–child link is no longer at play for teenagers living in single-mother households, for whom the influence of their only cohabiting parent turns out to be predominant independently of gender.
