a game theoretic approach for pricing greening and social welfare policies in a supply chain with Government Intervention
Journal of Cleaner Production, 2018Co-Authors: Mohammadreza Sinayi, Morteza RastibarzokiAbstract:Abstract It is undeniable that every organization and company will eventually need to move toward sustainability if they wish to survive and remain competitive. In order to attain sustainability, it is very important to optimize all its dimensions at the same time. In this paper, we consider a two-tier model consists of a supply chain and Government that Government in a higher level role as a leader for the whole supply chain. For both levels, three dimensions of sustainability, namely economic, social and environmental dimensions, are defined and each is considered in modeling. In this paper, consumer surplus is considered as an indicator of social welfare for the social dimension of sustainability, and for the first time, consumer surplus is modeled based on two variables that one is price and other is greening level of the product. Our findings show how the consumer surplus may increase as product price rises. Our findings also show that cooperation between the manufacturer and retailer always lead to produce a greener product, increase the profit of the entire supply chain and increase consumer surplus of customers. Also in models with Government Intervention, the Government imposes (pays) a lower (greater) tax (subsidy) on the final price of the product. We also find that the retail price in the cooperation models always is not lower than that in the noncooperation models which contrasts with the result of ‘double marginalization’. Results also show that different Government policies have significant impacts on the profit of the supply chain members as well as on the environment. Incorporating a fraction of consumer surplus in the Government utility function has a greater effect on the supply chain members' profit, and on the green degree of the product, than considering environmental concerns. We also propose a contract to coordinate the decentralized supply chain.

Government Intervention efficiency wages and the employer size wage effect in zimbabwe
Journal of Development Economics, 1997Co-Authors: Ann D VelenchikAbstract:Abstract This paper uses matched employer-employee data from a survey of 201 manufacturing firms and 1609 of their workers conducted in Zimbabwe in the summer of 1993. The results indicate that there is a substantial premium associated with employment in larger firms, and that this premium cannot be explained by differences in worker quality and job characteristics, nor is it eliminated by controlling for unionization, minimum wages or other forms of Government Intervention. The size premium is much larger for white collar than for blue collar workers. These differentials are also found to be substantially larger than those estimated for other developed and developing countries. The analysis uses the data about firm characteristics to explore a number of efficiency wage-based explanations of the size differential, and finds results which are consistent with, but not conclusive proof of, hiring, turnover, and morale based notions of efficiency wages.

mass migration unions and Government Intervention
Journal of Public Economics, 1994Co-Authors: Christoph M Schmidt, Anette Stilz, Klaus F ZimmermannAbstract:The widening gap between the dismal economic situation in the less developed economies and the economic prospects of migrants to Western economies has generated a potential for mass migration. At the same time, the developed economies have experienced high and persistent unemployment among their unskilled workers who would have to compete with new immigrants. We use a model that distinguishes labor markets by skill and concentrate on the imperfectly competitive mechanism of wage determination in the unskilled labor market to demonstrate that additional immigration might be beneficial precisely because of potential replacement effects. If the wages of skilled workers are positively affected by additional unskilled labor, this may lead to higher employment and output. Our results thus qualify standard economic reasoning based on competitive models or on the literature on rural-urban migration in developing countries.

green supply chain coordination considering Government Intervention green investment and customer green preferences in the petroleum industry
Journal of Cleaner Production, 2020Co-Authors: Xiang Zhang, H Abaid Ullah M YousafAbstract:Abstract Supply chain players in emissions-intensive industries are not likely to be motivated to make appropriate green improvements because significant investment is required for innovation and process improvement. This study aimed to analyze green supply chain coordination through which high supply chain performance can be achieved and green improvements and customer green preferences are considered. We proposed a two-part tariff (TPT) contract involving Government Intervention in terms of tax or subsidy. We demonstrated that the proposed TPT contract can achieve global supply chain optimization and aid in achieving green improvement. We further illustrated that the optimal green improvement degree is influenced by green technology investment, Government Intervention, and additional demand from customer green preferences. We showed that stronger Government Intervention may not always lead to higher green improvement and Government should switch from taxes to subsidies in the high green investment cost scenario. Moreover, the Government can benefit from low-cost green technologies. This study indicates that appropriately planned Government Intervention can increase the supply chain performance and aid in achieving sustainable goals.
