ResumoEste estudo buscou investigar as motivações subjacentes ao comportamento de comunicação boca a boca eletrônica (BAB-e) positiva sobre produtos, serviços e marcas no site de redes sociais Facebook, no contexto brasileiro. Para tanto, foram desenvolvidas hipóteses de pesquisa e um modelo teórico para se entender as motivações da comunicação BAB-e positiva nesse contexto. A fim de testar a validade do modelo proposto, um levantamento amostral foi conduzido com 468 usuários do site no Brasil. Os dados foram analisados por meio de modelos de equações estruturais. Os resultados sugerem como motivações significantes a preocupação com outros consumidores e o desejo de interação social, assim como os desejos de extravasar emoções positivas e de ajudar a empresa. A hipótese que previu que as recompensas econômicas afetam positivamente a comunicação BAB-e positiva não foi confirmada, assim, sugerindo que as motivações deste comportamento no Facebook são de natureza social e psicológica mais do que puramente econômica. O teste empírico deu suporte ao papel moderador da força dos laços sociais na relação entre preocupação com outros consumidores e comunicação BAB-e positiva.Palavras-chave: comunicação boca a boca eletrônica; motivações; redes sociais; sites; Facebook. AbstractThe purpose of the present study is to investigate the underlying motivations for positive electronic word of mouth (eWOM) behavior about products, services and brands by Brazilian Facebook users. Research hypotheses and a theoretical model were developed to further our understanding of positive eWOM communication motivations. A survey was conducted with 468 Facebook users in Brazil in order to empirically test the validity of the proposed model. Data was analyzed using structural equations models. Results suggest that concern for other consumers, the desire to engage in social interactions, as well as the desire to share positive emotions and help companies are significant motivations. The hypothesis which predicted that economic rewards are correlated with positive eWOM communication was not confirmed, suggesting that social and psychological motivations are more correlated with eWOM behavior than purely economic reasons for Brazilian Facebook users. The empirical test supported the moderating role of tie strength in the relationship between concern for other consumers and positive eWOM communication.

Significance Livestock supply chains account for 14.5% of global greenhouse gases (GHG) emissions. There is a consensus that approaches that improve cattle productivity while enhancing carbon sequestration can contribute to the multiple goals of improving ranchers’ livelihoods and mitigating climate change. Identifying policies that simultaneously increase productivity and sequestration is therefore critical to promote sustainable growth in the livestock sector. This paper documents the impact of training and technical assistance on pasture restoration and productivity in Brazil. We found that providing technical assistance to previously trained producers promoted pasture restoration, induced farmers to use more inputs, helped them improve their practices, and increased productivity and carbon sequestration. These findings highlight the importance of providing customized information to ranchers to help them sustainably intensify.
