DECISION MAKING TO MIGRATE AMONG PORTUGUESE ADOLESCENTS : A CASE OF COMPLEMENTARY OF ECONOMETRIC AND PSYCHOLOGICAL PERSPECTIVES FOR THE STUDY OF SOCIAL PHENOMENA.

Abstract : The aim of the present work was to show the complementarity of econometric and psychological approaches for the study of social phenomena through the study of migration decision making in Portuguese adolescents. Results concerning the relationship between intent to migrate and three other factors: two economic factors, namely wage differential and employment opportunity (first study), and a non economic, social factor that is called the network factor (second study). The hypotheses tested in this study were derived from econometric models. They were that of a main effect of the three factors and that of interactions between wage differential and job opportunities, between network factor, wage differential and job opportunities. The study was an application of the Functional Theory of Cognition. Study 1 showed that (a) the intent to migrate was higher when job opportunities were high and wage difference was high, and (b) the two factors interacted in a multiplicative way. Study 2 showed that: (a) the intent to migrate was higher in the network condition, (b) the effect of wage differential was higher when employment opportunities were good than when they were poor, and vice-versa, (c) the effects of wage differential and employment opportunities were higher in the network condition, and (d) the way in which employment opportunities altered the effect of wage differential varied as a function of the network factor. These findings hold independently of gender and social economic status of participants.
