Asymmetric effects of online consumer reviews

Consumers tend to seek heuristic information cues to simplify the amount of information involved in tourist decisions. Accordingly, star ratings in online reviews are a critical heuristic element of the perceived evaluation of online consumer information. The objective of this article is to assess the effect of review ratings on usefulness and enjoyment. The empirical application is carried out on a sample of 5,090 reviews of 45 restaurants in London and New York. The results show that people perceive extreme ratings (positive or negative) as more useful and enjoyable than moderate ratings, giving rise to a U-shaped line, with asymmetric effects: the size of the effect of online reviews depends on whether they are positive or negative.

The concept of 'economic activity' in the EU treaty: from ideological dead-ends to workable judicial concepts. Research Paper in Law 06/2011

[From the Introduction]. The economic rules, or put more ambitiously, the economic constitution of the Treaty,1 only apply to economic activities. This general principle remains valid, even if some authors strive to demonstrate that certain Treaty rules also apply in the absence of an economic activity,2 and despite the fact that non-economic (horizontal) Treaty provisions (e.g. principle of nondiscrimination, rules on citizenship) are also applicable in the absence of any economic activity.3 Indeed, the exercise of some economic activity transcends the concepts of ‘goods’ (having positive or negative market value),4 workers (even if admitted in an extensive manner),5 and services (offered for remuneration).6 It is also economic activity or ‘the activity of offering goods and services into the market’7 that characterises an ‘undertaking’ thus making the competition rules applicable. Further, it is for regulating economic activity that Article 115 TFEU, Article 106(3) TFEU and most other legal bases in the TFEU provide harmonisation powers in favour of the EU. Last but not least, Article 14 TFEU on the distinction between services of general economic interest (SGEIs) and non-economic services of general interest (NESGIs), as well as Protocol n. 26 on Services of General Interest (SGIs) confirm the constitutional significance of the distinction between economic and non-economic: a means of dividing competences between the EU and the member states. The distinction between economic and non-economic activities is fraught with legal and technical intricacies – the latter being generated by dynamic technological advances and regulatory experimentation. More importantly, however, the distinction is overcharged with political and ideological significations and misunderstandings and, even, terminological confusions.8

Controle judicial de políticas públicas no Brasil : limites da intervenção do poder judiciário na execução de políticas públicas para efetivação dos direitos fundamentais sociais à prestação

O Controle judicial das políticas públicas necessárias para a efetivação dos direitos constitucionais sociais à prestação é tema muito polêmico na atividade jurisdicional brasileira. Há os que defendem a intervenção irrestrita na tarefa de impor à administração pública a qualquer custo a efetivação das políticas públicas de sua competência. Contudo o nosso trabalho defende que a intervenção do Poder Judiciário no controle de políticas públicas é possível, segundo comando constitucional contido no artigo 3º da Carta Magna, mas com limitações para evitar a violação do princípio da separação dos poderes. Para demonstrar a nossa concepção sobre o tema partimos da definição e da natureza dos direitos fundamentais sociais e sua concepção na ordem constitucional brasileira. Analisamos as principais funções dos direitos fundamentais, concentrando a nossa atenção na função prestacional, ou direito a prestação em sentido estrito. Nesse particular passamos a discutir as questões que envolvem a efetivação dos direitos fundamentais sociais, a partir de sua eficácia jurídica e social até aos aspectos referentes a sua concretização. Salientamos que a efetivação dos direitos fundamentais sociais “derivados” passa por uma atividade legislativa de conformação antes de sua efetivação e que os “originais” poderiam ser concretizados imediatamente, sem se descurar da necessidade de outra atividade legislativa de destinação dos recurso públicos através da lei orçamentária, na foi ressaltado que deveria ser tomado como um dos critérios para essa destinação o princípio do “mínimo existencial”. Analisamos a tese recorrente de defesa da administração para justificar a não efetivação dos direitos sociais à prestação, a denominada “tese da reserva do possível”, salientamos que embora relevante, não era absoluto esse argumento. Contudo a atuação jurisdicional no controle das políticas públicas, não pode fugir da atenção aos princípios da razoabilidade e da proporcionalidade.
