The first aim of this research is to provide a novel methodology using a full set of “ex-ante” alternatives aimed at investigating migration choices under a RUM (Random Utility Model) approach. Using laboratoryexperiments, we will assess the empirical relevance of the RUM approach to migration. One of the most interesting by-products of such an approach is to test directly the validity of the Independence of Irrelevant Alternatives (IIA) hypothesis, which is often used inRUM models of international migration. We will also uncover the role of the main determinants of migration intentions and the specific role of pre-migration information. We will measure through lab-in-the-field games, the individual risk aversion andtime preferences . We will integrate these parameters to estimate the role of these additional individual characteristics in influencing the propensity to move and the location choice.
