There is a range around reference prices, the so-called latitude of price acceptance, where consumers seem insensitive to changes into prices, with these ranges being wider for buyers of private brands. This paper analyses objective price gap between two product alternatives as a main driver of consumer behaviour. Therefore, the authors shed light on whether the price gap conditions consumer-switching behaviour and at what point the price gap triggers a switching pattern.

Shopping data on two product alternatives of olive oil were obtained from a household scanner panel of Spanish consumers (607 households) with weekly price tracking, and multilevel regression models were performed.

The results suggest that the price gap has a fundamental effect on the consumers' choice. In this case, up to 1 euro/litre the demand seems almost inelastic; beyond that price gap, the demand for the finer product plummets.

This study focussed on olive oil products. The research needs to be extended other food products.

The authors contribute to the literature by documenting how the price context measured in terms of a price gap is a relevant stimulus in consumer choices, with a focus on the change in price sensitivity between product alternatives when competing brands are not involved but private brands are.

This chapter examines the delicate balance achieved by apex courts in new democracies when dealing with impunity for rights violations during times of transitional justice. While international law has clearly rejected amnesties for past rights violations, domestic politics sometimes incorporate amnesties as part of larger peace settlements. This puts courts in the difficult situation of balancing the competing demands of law and politics. Courts have achieved equipoise in this situation by adopting substantive interpretations and procedural approaches that use international law’s rights-based language but without implementing international law’s restrictions on amnesties. In many cases, courts do this without acknowledging the necessarily pragmatic nature of their decisions. In fact, oftentimes courts find ways of avoiding having to make any substantive decision, effectively removing themselves from a dispute that could call into question their adherence to international legal norms that transcend politics. In doing so, they empower political actors to continue down the road toward negotiated peace settlements, while at the same time protecting the courts’ legitimacy as institutions uniquely situated to protect international human rights norms – including those they have effectively deemphasized in the process.

This study aims to identify how Spanish consumers’ extrinsic preferences for food have evolved by examining the extant literature on food preferences in Spain, focusing on food-related attributes and food-related values.

This study is based on a synthetic review of the extant academic literature on Spanish consumer preferences for food-related attributes and food-related values from the mid-20th to the 21st century. This study uses key economic and social milestones that are most likely to influence food value chain actors to show how consumer preferences have evolved over the study period.

Spanish consumer food attribute preferences expanded as the food sector of the nation continued to grow, and value preferences showed a similar pattern from the mid-20th to the 21st century. The drivers of these preferences were trust, lifestyle, education (campaigns), sociodemographic factors and purchasing power.

Evaluating the extant literature’s contribution to consumer preferences for food-related attributes and values is important because it can aid in understanding the hierarchy and variety of consumers’ food preferences as well as the factors that drive these preferences. To the best of the authors’ knowledge, this study is the first to explore how Spanish consumer preferences evolved between the mid-20th and 21st centuries.
