The paper analyses optimal investment in physical and human capital when the (exogenous) rate of population growth changes. The growth model describes a closed economy with overlapping generations and homogeneous human capital. The optimal growth path is characterized by two groups of optimality...

The paper presents probability models to recover information on migration flows from incomplete data. Models are used to predict migration and to combine data from different sources. The parameters of the model are estimated from the data by the maximum likelihood method. If data are incomplete,...

This paper addresses the question of how to formally represent the spatial structure of an observed origin-destination-specific pattern of interregional migration flows. Such a representation allows an analyst to compare the spatial structures of different migration regimes and contrast their...
