OBJECTIVE The aim of this study was to formulate an objective clinical and geometric relationship between Cobb angle and the difference between the lengths of convex and concave sides (convexo-concave vertebral difference) of the structural curve in scoliosis. Is it possible to express Cobb angle in such a way that it could be visualized as a length, especially while planning for surgical corre...

In this paper a re-examination of the original time-series data sets used by Professor Douglas and associated researchers to establish the existence of an aggregate production function is undertaken. Particular attention is paid to the issue of whether the data provide deductive support for the ‘Laws of Production’ as claimed by Douglas (1948). Various statistical methods are used to analyse th...

In this paper we examine whether nonlinearities in the aggregate production function can explain parameter heterogeneity in the Solow (1956) growth regressions. Nonlinearities in the production technology are introduced by replacing the linear Cobb-Douglas specification with the more general CES specification. We justify our choice of production function by showing that in the context of cross-...

Although a number of different models have been suggested for the process that brings workers and firms together in the labour market, none of these performs well in empirical studies of the aggregate matching function. Empirically, the most successful functional form is Cobb-Douglas, for which there are no microfoundations in the existing literature. I present a new model for the matching proc...
