El. knyga: Increasing Returns and Efficiency

Increasing returns to scale is an area in economics that has recently attracted much attention. The commodities produced with technology exhibiting increasing returns constitute an important component of economic activity in a modern economy. They are typically commodities produced either by a public sector or, as in the United States, by regulated utilities.
The central issue in this book addresses how to manage the public, or regulated, sector of the economy in order to achieve efficient resource allocation while maintaining the advantages of a decentralized market mechanism within the private sector. Quinzii's novel approach lies in the analysis of increasing returns by consistently using the framework of general equilibrium theory. This approach permits the welfare implications of pricing policies in the public sector without neglecting to take into account the interactions between production in the public and in the private sector, an important component of these being the effects on the distribution of income created by the need to finance the public sector. A significant contribution of this work is its analysis of the problem of financing the public sector in a way in which it is acceptable not only to individual agents but also to all sub-groups of agents as well.
The discussion and exposition of key ideas have been kept as intuitive as possible, with simple examples and a geometric approach to illustrate basic points and to motivate the readers' own intuition. While based on the research of the author, the work draws extensively on recent literature on increasing returns. Quinzii has made a special effort to relate the latest developments in the field of increasing returns with earlier economic literature, in particular the marginal price cost pricing controversy of the 1940s.

Increasing returns to scale is an area in economics that has recently become the focus of much attention. While most firms operate under constant or decreasing return to scale on their relevant range of production, some firms produce goods or services with a technology which exhibits increasing returns to scale at levels of production which are large relative to the market. These goods are an important component of economic activity in a modern economy and are typically commodities produced either by a public sector or, as in the U.S., by regulated utilities. In this study, the author analyzes increasing returns using general equilibrium theory to take into account the interactions between production in the public and the private sector, and the effects of financing the public sector on the redistribution of income.
