The results show that, the equilibrium output and the optimal social welfare under the RD investment subsidy policy are both less than those under the product subsidy policy; the optimal RD investment under the RD investment subsidy policy is less than that under the product subsidy policy; and the RD product subsidy has a more obvious incentive effect on firm RD investment. Under the background of the leading edge of technology of foreign firms, the product subsidy policy drawn up by the government to encourage RD innovation of domestic firms is more effective than the RD investment subsidy policy.展开更多

Such losses are asymmetrically distributed within the various regions of the country. Meter tampering (fraud), meter bypassing by regular consumers (theft) and irregular hookups to the network by unlawful consumers are the most predominant forms of irregularities. Part of it which is caused by non-technical losses is being passed on to the consumers through the tariffs they pay. This paper presents an overview of the current situation related to non-technical losses in Brazil involving: quantification, regional asymmetry, nature and stratification, tariff management, and strategies employed to its reduction. Advanced measurement techniques provided by smart-grids can significantly reduce them. It is suggested a potential reduction of 60%. An innovative way of using these indicators in order to identify irregularities is briefly presented in this work.展开更多
