We propose a method for spatial principal components analysis that has two important advantages over the method that Wartenberg (1985) proposed. The first advantage is that, contrary to Wartenberg's method, our method has a clear and exact interpretation: it produces a summary measure...

The sign of worker remittances in growth regressions is heavily disputed in the literature. Comparing two growth regressions with different signs for the remittance variable we show that collinearity with the lagged dependent variable might indicate that collinearity should be investigated...

We show empirically that aid given to poor developing countries enhances growth and reduces emigration once several dynamically interacting effects of aid are taken into account in a system of equations. We estimate equations for net immigration flows as a share of the labour force and GDP per...

In this paper, we combine the export-led and import-led growth hypotheses in a growth model in which the importation of foreign capital goods and the demand elasticities of own export products explain the growth opportunities and the technical progress of developing countries. This model, based...

We are interested in the relation between Gini coefficients of education, educational variables, and growth. We specify a system of 14 difference equations with lagged dependent variables in education variables, as well as a growth regression, auxiliary equations for savings and investment...
