Inequality in exposure to air pollutants: A new perspective.

In research and policy design we mainly use a 'population weighted average concentrations' perspective to study changes in air quality, to evaluate if past policies have been effective, or to assess the impact of future air quality plans. This angle is useful and informative, but sometimes masks other important patterns. In this paper we propose to add, to the existing population weighted average point of view, a new indicator that brings to the fore the 'inequalities' in exposure. This inequality indicator is based on the Gini coefficient, usually applied in Economics and here considered to evaluate if exposure to air pollutants is equally distributed among population. A case study for this new indicator is then proposed, to assess the evolution of exposure to air pollutants in Europe from 2000 to 2018, in terms of both average exposure and inequality levels. The results show that using only average exposure metrics can mask other interesting patterns, and confirm the benefits of including this alternative perspective into the analysis.

Exploring the influence of consumer characteristics on veal credence and experience guarantee purchasing motivators.

In Europe, in the last decades, public administration has encouraged extensive livestock farming systems, usually related to high quality meat and the preservation of endangered local breeds. Nevertheless, its continuity in the near future should be based on adapting it to the market requirements. This paper investigates consumers' preferences heterogeneity towards veal attributes, as well as the linkage between a wide range of consumer traits and attributes that motivate purchasing of veal with unique characteristics. Main method of analysis included a choice experiment method. Findings showed that regional origin and health information play a stronger role than tenderness degree guarantee at the moment of choice. Moreover, regional origin is more relevant when it is linked to a local breed. Nevertheless, heterogeneous preferences have been detected. In contrast to the general trend, one-person households attach greater importance to the presence of a high degree of tenderness guarantee. Furthermore, younger consumers value more this guarantee, while expert consumers do not.
