In this paper the issue of mathematical programming and optimization has being revisited. The theory of optimization deals with the development of models and methods that determine optimal solutions to mathematical problems defined. Mathematical model must be some function of any solution that...

The aim of this paper is to investigate the issue of R&D investment and the market value of the firm. This idea dating back from Arrow paper, later developed by Paul Romer but in the area of economic growth. Zvi Griliches (1979), first introduced the production function, which later would be...

The issue of institutional support for innovations in Latin American countries has been examined in this paper. We use aprirori theoretical knowledge on this issue in order to derive one econometric model out of a theoretical framework. The influence on human capital variable on innovations...

In this paper the issue from personnel economics such as work intensity has been investigated. George Akerlof back in 1976 argued that the real life failed to correspond to the standard general equilibrium model set by Arrow-Debreu. In the real life information is neither complete nor it’s...

In this paper the issues from the personnel economics has been investigated. The issues such as training of workers from Becker’s human capital theory and their association with the workers’ productivity. In the second part of the paper the issue of grooming has been investigated in relation...

In this paper we use pooled cross-sectional (longitudinal data) in a sample of 10 Balkan countries. The period we cover is from 1950-2009 data are for population and economic growth. In the theoretical part we present optimal intergenerational model of population growth. The optimal population...
