The main objective of this research is to develop a model that shows how far the migration process can go on in this context.Agriculture, construction, personal services, as spatially constrained, create a share of labour demand that cannot be delocalised and demographic change brings about an increase in the demand for personal services that can be provided easily by low skill migrant workers. But it is less clear what is going to happen in the other sectors of the economy.In manufacture, substitution of national workers with immigrants is going on, but at the same time delocalisation is also going on.Although it is less evident, the same is happening in the service sector.In the first part of our research we will make a very strong assumption: all domestic workers can be substituted by immigrated workers, one by one i.e. the only limit to migration is given by the domestic demand for labour.So far we would like to develop a model that show us how far the process of delocalisation can go on. It means to identify the share of labour that has to be located inside the country, given its domestic demand.The methodology consists in separating the productive and the distributive labor component of each sector splitting the labor coefficients in two parts: one related to the part of the work that can be done in isolation and one to the work that should be provided face to face. Then by using an I/O approach we will estimate the share of labour that must be located inside the country. The second step consists in rejecting the above assumption and working in a more detailed way on the structure of labour skills that will be necessary after the hypothetical delocalisation process has been completed. This structure should be compared with the structure of labour skills provided by migrants.The country chosen for our exercise is Italy.
