Ñopo, Hugo; Alberto Chong y Juan Camilo Cárdenas (2008). Stated Social Behavior and Revealed Actions: Evidence from 6 Latin American Countries Using Representative Samples. Inter-American Development Bank, Publications (Working Papers) 4575.

The paper explores the link between what people say they prefer to do and what they actually do. Using data from an experimental project exploring trust and pro-sociality for representative samples of individuals in six Latin American capital cities, the paper links the results of these experiments with the responses obtained from representative surveys to the same participating individuals. Individuals with higher agreement with a set of pro-social statements are those more willing to contribute and collaborate to the social welfare in the community, and what people say is linked to what people do. This supports the idea that the inclusion of subjective controls in the lefthand- side in an empirical specification does carry useful information.
