The object of this paper is to derive measures for the changes in physical labour productivity and to apply them to the case of Italy during the 1995-2000 period. Firstly, section 1, introduces the historical development of selected literature on labour productivity measurement using the notion...

Computer-owners combine complementary goods to a computer-system. They exchange data with others and between different applications. These interdependencies lead to three different network effects, which are explained in the framework of Hotelling models. In the framework of a one-dimensional...

The article addresses the question 'What makes an e-shop successful?' by providing various reference models. These reference models are for the obvious retail evolution, for quality and retail sales, for pricing and quality of products, and for pricing and quality of the sales process (i.e.,...

The paper refers to the well-known Tsukui turnpike theorem on convergence of optimal growth trajectories in the closed dynamic Leontief model to the maximum balanced growth trajectory, called turnpike. In the original proof of this theorem, the assumption that the matrix B of capital...

This paper shows that the dynamic Leontief model can be interpreted as a linear model of endogenous growth. The long-term rate of growth is determined within the economic system - either as the outcome of the saving and investment behaviour of agents or as the outcome of some planner's...

This paper is concerned with a comparison of the treatment of fixed capital in some multi-sectoral models. First, the dynamic Leontief model is investigated. Scrutiny shows that this model suffers from conceptual misconceptions which result from restrictive assumptions concerning full-capacity...

This paper is concerned with the treatment of fixed capital in multisectoral models. Five approaches and concepts developed and used by Sraffa and von Neumann, by Hicks, by Georgescu-Roegen, by Walras and by Leontief are compared. These five approaches fall into two broad categories: models with...

The purpose of this paper is to determine the main directions of integration processes in the dairy industry of Ukraine. Since Ukraine’s independence, situation in the dairy processing deteriorated substantially, that adversely impact on an activity result of dairy enterprises and...

There are many ways to measure productivity. The choice will depend on the suitability of each index to the main purpose the researcher has in mind. Whenever we are interested in 'competitiveness', the proper measure will be the inverse of the total labour embodied in one unit of final product;...

The paper aims at estimating the innovation impact of the vertical integration of knowledge intensive business services (KIBS) into manufacturing. Referring to the vertically integrated sectors of an economy allows innovative knowledge, which is transferred directly and indirectly from KIBS to...
