Separate waste collection in mountain municipalities. A case study in Campania

This paper aims to analyse the impact of land characteristics (i.e. altimetry and housing dispersion) on separate waste collection, with a focus on mountain municipalities. The high spatial heterogeneity of the driving factors of separate waste collection allows traditional techniques, such as OLS, to offer only a partial depiction of the situation, missing important information. In this view, we perform the Geographically Weighted Regression (GWR), which allows to control for the local determinants of waste management. Our data cover 550 municipalities of Campania, in Southern Italy. We control for a set of morphological and socio-economic variables, drawn from official records for 2012. Our results show that the relationships between land characteristics and separate waste collection are not constant over space. Moreover, they suggest that in the presence of non-modifiable factors (such as land characteristics) local governments should act on citizen motivations, promoting awareness on environmental issues, and should implement time-saving collection methods.     

Pricing used books on Amazon.com: a spatial approach to price dispersion

This paper estimates a spatial autoregressive (SAR) model of price dispersion using publicly available internet bookselling data. It uses a semiparametric adaptive estimator that does not require the usual Gaussian assumption of maximum likelihood (ML) estimators. The results suggest that both price competition and seller heterogeneity are key drivers of the observed price dispersion. The paper finds that sellers with large sales volume, newly established sellers and US mainland states-based sellers tend to price lower. The identified significant spatial interaction is evidence of spatial price competition. Controlling for everything else, a seller asks a lower price when large sellers charge relatively high prices, which is also evidence of price-based selling and undercutting.

Consumer avoidance of specially priced items during social coupon redemption

Social coupons (SCs) (e.g., Groupon) differ from traditional or regular coupons (RCs) in that they require consumers to make a prepayment to receive substantive discounts. As the general rule of SCs prohibits double-promotion, SC consumers tend to engage in certain avoidance behaviors when experiencing another promotion (i.e., specially priced for selected items). The results across two scenario-based experiments reveal that SC consumers (vs. RC consumers) have a greater tendency to avoid specially priced items when redeeming a coupon for hedonic consumptions, but not for utilitarian consumptions. Such avoidance is due to one’s motivation to minimize the perception of deal waste.     

Understanding the antecedents of consumers' attitudes towards doggy bags in restaurants: Concern about food waste,culture, norms and emotions

Based on a qualitative study with 20 respondents in France and 20 respondents from the Czech Republic, this study aims to better understand how consumers’ concern about food waste, culture, social norms and emotions contribute to consumers’ attitudes and behaviors related to doggy bags. Results highlight a double paradox between conflicting norms and emotions: personal norms encourage not to waste while salient social norms encourage leaving leftovers; asking for a doggy bag generates immediate shame while leaving leftovers produces anticipated regret and guilt. Finally, the study sheds light on obstacles to overcome for the adoption of this social innovation.
