In this thesis, we extend Bai and Perron's (1998, Econometrica, pp. 47-78) method fordetecting multiple breaks to nonlinear models. To that end, we consider an unstable univariatenonlinear least squares (NLS) model with a limited number of parameter shifts occurring atunknown dates. In our...

Endogenous growth requires that non-reproducible factors of production be either augmented or eliminated. Attention heretofore has focused almost exclusively on augmentation. In contrast, we study factor elimination. Maximizing agents decide when to reduce the importance of non-reproducible...

Perpetual growth requires offsetting diminishing returns to reproducible factors of production. In this article we present a theory of factor elimination. For simplicity and clarity, there is no augmentation of non-reproducible factors, thus excluding the standard engine of growth. By spending...
