Non-Binding Voluntary Agreements

In reality, most voluntary agreements with polluters (VAs) are not enforceable in the sense that no legal tools are available to enforce Örmsí commitments. We examine whether such VAs are able to achieve an e¢ cient level of environmental protection when they are obtained under the legislative threat of a pollution quota. We show that they can improve social welfare relative to legislative intervention when lobbying Congress is very e§ective and when the polluter and the regulator do not discount future costs and beneÖts heavily. These Öndings suggest that VAs should be used selectively, taking into account sector characteristics and the degree of ináuence of lobbying on Congress.

Voluntary Agreements under Endogenous Legislative Threats

The paper analyzes the welfare properties of voluntary agreements (VA) with polluters, when they are obtained under the legislative threat of an alternative stricter policy option. In the model, the threat is an abatement quota. Both the threat and its probability of implementation are endogenous. The latter is the outcome of a rent-seeking contest between a green and a polluter lobby group influencing the legislature. We show that a welfare-improving VA systematically emerges in equilibrium and that it is more efficient than the pollution quota. We also discuss various VA design aspects.Environmental policy, voluntary agreements, bargaining, legislatures, rent seeking, rent-seeking contests

Does foreign environmental policy influence domestic innovation? Evidence from the wind industry

This paper examines the relative influence of domestic and foreign renewable energy policies on innovation activity in wind power using patent data from OECD countries from 1994 to 2005. We distinguish between the impact of demand-pull policies (e.g., guaranteed tariffs, investment and production tax credits), as reflected by wind power capacities installed annually, and technology-push policies (government support to R&D). We show that inventors respond to both domestic and foreign new capacities by increasing their innovation effort. However, the effect on innovation of the marginal wind turbine installed at home is 28 times stronger than that of the foreign marginal wind turbine. Unlike demand-pull policies, public R&D expenditures only affect domestic inventors. A simple calculation suggests that the marginal million dollars spent on R&D support generates 0.82 new inventions, whereas the same amount spent on the deployment of wind turbines induces, at best, 0.06 new inventions (0.03 locally and 0.03 abroad)

Distributional effects of road pricing: Assessment of nine scenarios for Paris

The starting point of this paper is to consider that there is no general answer to the question of the equity of urban road pricing. We therefore simulate and compare the distributional effects on commuters of nine toll scenarios for Paris, assuming that utility is nonlinear in income. We show that the distributional pattern across income groups depends crucially on the level of traffic reduction induced by tolling. Stringent tolls are more favourable to low-income motorists. Equity effects also vary with toll design. Compared to a reference scenario which uniformly charges all motorists driving within Paris, an inbound cordon toll is detrimental to low-incomes. Conversely, granting a rebate to low CO2 emission cars slightly improves their situation while an exemption for Paris residents is neutral. Surprisingly, it matters little for social equity whether toll revenues are allocated to all commuters or solely to public transport users.Road pricing, Distributional effects, Income effects, Equity

The political economy of emission tax design in environmental policy

In actual environmental policy, the design of actual pollution emission taxes differs significantly with the optimal Pigovian tax. In particular, earmarking prevails and actual taxes are usually combined with regulation. Furthermore tax rates are generally too low to significantly influence polluters' behavior. The paper develops a political economy model to explain these design parameters: the tax rate, earmarking pattern and whether the tax is combined with a regulation. An incumbent government selects these parameters under the influence of a green and a polluters' lobby groups. An earmarked tax is introduced in equilibrium which rate is lower than the regulatory shadow price when the status quo regulation is imperfectly enforced and if the green lobby is sufficiently weak

The cost efficiency of voluntary agreements for regulating industrial pollution: A Coasean approach

This paper deals with the cost efficiency of target-based voluntary agreements for reducing industrial pollution. These agreements are contracts between a public body and an industrial association including the collective commitment of the industrial sector to reach a pollution abatement objective. In this respect, cost efficiency properties of these VAs are determined by the way burden sharing is carried out between individual firms at the implementation stage of the contract. To address this question, we develop a Coasean (neo-institutional) model which assesses the ability of the VA's burden sharing scheme based on inter-firm bargaining to minimise transaction costs. In a first part, we present the nature of the problem and discuss why a Coasean approach is suitable to deal with our question. In the next two parts, the analytical framework is presented. The assessment is carried out in the last part. In comparison with economic instruments and command and control approaches, we show that VAs are cost efficient in the following context: very large shared uncertainty about pollution abatement techniques, concentrated industrial sectors in which the heterogeneity in pollution abatement activities and costs is low

The Clean Development Mechanism and the International Diffusion of Technologies: An Empirical Study

The Clean Development Mechanism (CDM) is expected to stimulate the North-South transfer of climate-friendly technologies. This paper provides an assessment of the technology transfers that take place through the CDM using a unique data set of 644 registered projects. It provides a detailed description of the transfers (frequency, type, by sector, by host country, etc.). It also includes an econometric analysis of their drivers. We show that transfer likeliness increases with the size of the projects. The transfer probability is 50% higher in projects implemented in a subsidiary of Annex 1 companies while the presence of an official credit buyer has a lower – albeit positive – impact. The analysis also yields interesting results on how technological capabilities of the host country influence technology diffusion in the CDM.Kyoto Protocol, Clean Development Mechanism, International Technology Transfer

Technology transfer by CDM projects: A comparison of Brazil, China, India and Mexico

In a companion paper [Dechezleprêtre, A., Glachant, M., Ménière, Y., 2008. The Clean Development Mechanism and the international diffusion of technologies: An empirical study, Energy Policy 36, 1273–1283], we gave a general description of technology transfers by Clean Development Mechanism (CDM) projects and we analyzed their drivers. In this paper, we use the same data and similar econometric models to explain inter-country differences. We focus on 4 countries gathering about 75% of the CDM projects: Brazil, China, India and Mexico. Sixty eight percent of Mexican projects include an international transfer of technology. The rates are, respectively, 12%, 40% and 59% for India, Brazil and China. Our results show that transfers to Mexico and Brazil are mainly related to the strong involvement of foreign partners and good technological capabilities. Besides a relative advantage with respect to these factors, the higher rate of international transfers in Mexico seems to be due to a sector-composition effect. The involvement of foreign partners is less frequent in India and China, where investment opportunities generated by fast growing economies seem to play a more important role in facilitating international technology transfers through the CDM. International transfers are also related to strong technology capabilities in China. In contrast, the lower rate of international transfer (12%) in India may be due to a better capability to diffuse domestic technologies.
