Aim of the model
The aim of PRIDE is to provide an integrated assessment of policy instruments for cost-efficient climate mitigation. The model represents utility and profit-maximizing economic sectors that are relevant for energy-economic mitigation policy, i.e. households, production, fossil and renewable energy firms and fossil resource owners. Furthermore, a government imposes policy instruments (taxes, subsidies, permits, quotas, feed-in-tariffs, etc.) in order to achieve climate protection. The model is calibrated at a global scale in order to consider the dynamics of fossil resource supply appropriately.
Typical research questions are:
- What is the optimal policy mix (carbon pricing and technology policy) to achieve low-carbon stabilization and least costs?
- What is the performance of several second-best policies (carbon pricing only, renewable energy subsidies only, etc.) compared to the first-best policy mix?
- How do several first-best and second-best instruments influence energy prices, fossil and renewable energy rents, labor and capital income, and taxes?
Market failures integrated in PRIDE:
- Open-access atmospheric carbon budget (missing carbon price)
- Learning-by-doing spillovers
- Discount rate mark-ups in several sectors (e.g. due to insecure property rights/risk premiums)
- Imperfect competition in financial intermediation
