Using the capability approach as conceptual framework, the present study examines empirically the effect of job characteristics on subjective well-being. First, I suggest a measurement model for four latent job characteristics, using a confirmatory factor analysis. Then, I examine the job...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors, spanning the space of Engel curves. Once the common factors are estimated via approximate principal components, we identify them by imposing...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors and we estimate a base of the factor space by means of approximate principal components. We assume that the extracted factors span the same space...
