The paper describes OptiHab study, done in the framework of the MARIE project. The objective of OptiHab is to provide technical and economic information to optimize the energy renovation of residential sector in Catalonia, ensuring the comfort of the users. The information of the study gives the criteria to develop regional strategies and policies to improve the energy efficiency of the residen...

We investigate an automobile supply chain where a manufacturer and a retailer serve heterogeneous consumers with electric vehicles (EVs) under a government’s price-discount incentive scheme that involves a price discount rate and a subsidy ceiling. We show that the subsidy ceiling is more effective in influencing the optimal wholesale pricing decision of the manufacturer with a higher unit prod...

The government as a policy maker wishing to promote remanufacturing and proper disposal of hazardous old products which are harmful to environment has taken many actions, ranging from carbon regulation and financial incentives such as trade-in subsidy. However, carbon tax can result in loss of profit for firms to some degree, so the government has to give other subsidy to balance the profits an...

We assess different policies for reducing carbon dioxide emissions and promoting the innovation and diffusion of renewable energy. We evaluate the relative performance of policies according to incentives provided for emissions reduction, efficiency, and other outcomes. We also assess how the nature of technological progress—whether it occurs through learning by doing or R&D investment, and the ...

Ecosystems are differentially open to subsidies of energy, material and organisms. This fundamental ecosystem attribute has long been recognized but the influence of this property on community regulation has not been investigated. We propose that this environmental attribute may explain variation in the strength of trophic cascades among ecosystems. Simply because of gravity, we should predict ...

Under perfect competition on the output market, first best technology subsidies in the presence of learning by doing are justified by knowledge spill overs that are not accounted for by individual companies. First best output subsidies are thus depending directly on the learning effects and are, if applicable, positive. Considering electricity markets, a setting of imperfect competition is more...

Despite some empirical evidence to the contrary, government subsidies to higher education are usually presumed to be inequitable because college-educated workers earn more than less educated workers. Using a simple model of educational choice with endogenous wages and two worker types, I obtain strong results concerning this conflict between effi ciency and equity —namely that equity and effi c...

The Affordable Medicines Facility for malaria (AMFm) was conceived as a global market-based mechanism to increase access to effective malaria treatment and prolong effectiveness of artemisinin. Although results from a pilot implementation suggested that the subsidy was effective in increasing access to high-quality artemisinin combination therapies (ACTs), the Global Fund has converted AMFm int...
