this paper studies the effects of the structural variables of the iranian industries sector on the welfare cost using to the structure-conduct-performance (scp) theory. in other words, we investigate the role of structural components and their effects on the size of the welfare cost in iran's industry sector. we have used the leibenstein's model to calculate the deadweight loss and then the pan...

The main objective of this research is to evaluate the social costs of monopoly in Iranian concentrated industries during 1996-2006. Leibenstein approach has been employed to evaluate the social costs. Leibenstein believed that most monopolistic industries operate inefficiently because of being in the safe margin. Hence, he proposed that the costs of inefficiency be added to the welfare triangl...

ing from its dynamic effects on the economy, the potential benefits from deregulation of an inefficiently regulated sector may be illustrated in a simplified scheme first worked out by Harberger (1954) for the estimation of welfare losses from monopoly20. In this case, the Harberger measure of welfare loss corresponds to that part of the reduction in consumer surplus which is not appropriated b...

This paper develops an analytically tractable Bewley model of money demand to shed light on some important questions in monetary theory, such as the welfare cost of inflation. It is shown that when money is a vital form of liquidity to meet uncertain consumption needs, the welfare costs of inflation can be extremely large. With log utility and parameter values that best match both the aggregate...

Abstract This introduction discusses recent developments in the Nordic welfare states as well an overview of contributions to this regional issue on states. The focuses topics demography, financing, solidarity, and migration. points a potential conflict between resource availability, user expectations, norms professionalism. Navigating ‘Bermuda triangle’ will likely require constant negotiation...

Our main aim was to identify and prioritize the obstacles to the implementation of decent work in the industry. The current research was applied in terms of purpose. It was also descriptive survey in terms of collecting data. Due to the large extent of industry sector actors, only one side of the main actors' triangle in the industrial sector in Yazd province was selected as the statistical sam...

We often need to refer to adjacent elements (e.g., vertices, edges and faces) in triangle meshes for rendering, mesh simplification and other processes. It is, however, sometimes impossible to prepare the enormous memory needed to represent element connectivity in gigantic triangle meshes. We proposed a memory efficient scheme for referring to adjacent faces around a vertex in non-manifold tria...
