| Among other applications, self-feeding has been used to study food preferences in fish allowing them to choose between feeders with different food content. Preference tests assume that (i) trigger actuations are motivated by appetite, (ii) fish can learn which feeder contains which food and discriminate between feeders solely on the basis of their content, and (iii) in groups of fish, the triggering preferences is representative for the individuals of the group. We studied individual triggering behaviour in four groups of 14 Atlantic cod (length of 34 +/- 2 cm, weight of 424 +/- 102 g, mean +/- SE, water temperature comprised between 7-8 degrees C) that were first given the choice between two self-feeders with identical content (Period 1 of 14 days) and... |

| Recent social spending inflation in China has led to its growth rate far exceeding that of income and other consumption. In this paper, we estimate private returns to social spending, such as higher social status and larger social network that serve as certain functions. In almost all specifications we find that gift spending has significant private returns, but the returns are biased towards richer households. Upon comparing different measures of centrality, we also find that social connections are more accurately characterized when weighted by their intensities (values), capturing their role in mobilizing scarce resource in the network. Furthermore, social status and network may change long-term income trajectory and the resulted consumption. However,... |
