This paper examines the role of the financial sector in renewable energy (RE) development. Although RE can bring socio-economic and environmental benefits, its implementation faces a number of obstacles, especially in non-OECD countries. One of these obstacles is financing: underdeveloped financial sectors are unable to efficiently channel loans to RE producers. The influence of financial sector development on the use of renewable energy resources is confirmed in panel data estimations on up to 119 non-OECD countries for 1980–2006. Financial intermediation, in particular commercial banking, has a significant positive effect on the amount of RE produced, and the impact is especially large when we consider non-hydropower RE such as wind, solar, geothermal and biomass. There is also evidence that the development of the RE sector has picked up significantly in the period since the adoption of the Kyoto Protocol.

This paper addresses the design of corrective taxation schemes to manage multiple, interacting stocks. In the setting of irrigation-induced salinity, a collective groundwater stock aliments a set of individual rootzone salt stocks. It is shown that the policy maker does not need to base the tax rule on the individual salt stocks. Indeed, taxes based on the level of input and on the collective stock induce the agents to achieve the socially optimal irrigation path. An even simpler instrument is sufficient if the policy-maker's goal is to reach optimality at the steady state only.

The goal of this paper is to analyze whether reforming groundwater pricing has the potential to encourage water conservation and assess its impacts on crop production and producer income in rural China. Household-level water demands are estimated so that adjustments at both the intensive and extensive margins are captured. The results show that a large gap exists between the cost of water and the value of water to producers. Simulation analysis shows that reforming water pricing can induce water savings. However, the price of water needs to be raised to a relatively high level. We also find that the value-based policy is more effective than the cost-based policy since it generates larger water savings, given the same increase in the average price of water. While raising the price of water negatively affects crop production and crop income, higher water prices do not adversely affect the distribution of household income.

We use a choice experiment to evaluate a hypothetical irrigation water pricing regime in Karnataka State, India. The proposed regime includes increasing the availability of water in the dry season, increasing irrigation frequency, water sharing with downstream water users, set against the introduction of a semi-volumetric irrigation price. The majority of farmers chose the status quo (SQ) option. Given the large heterogeneity in farmers’ SQ water availability, irrigation practices and current water tax payments, the SQ could not be given a unique baseline interpretation. This poses a potential problem for choice model estimation. By coding the individual SQ situation of farmers, we observed considerable increase in the explanatory power of the choice experiment models. The results may be of general interest for choice experiments of environmental goods and services with heterogeneous spatial distribution, heterogeneous respondents and/or contentious policies that are expected to elicit considerable SQ response.

Given the extensive discussion of China's air pollution and urban income inequality problems, relatively little attention has been paid to any relationship which may exist between the two. This paper seeks to do so, by exploring the existence of environmental equity in China. Specifically, we first calculate traditional measures of urban income inequality (the Gini coefficient and Theil's T and L indices) for the years 1995 and 2004. Then, we estimate ‘pollution-adjusted’ incomes using China-based health functions and economic valuation studies, and recalculate the income (or now welfare) inequality measures. The results indicate that as pollution cleanup efforts gain traction over time, the regressive consequences of pollution may diminish. We thus conclude with an encouraging note for developing countries: improving welfare distribution can coexist with an improving environment.

This study examines, with a focus on regional environmental states in China, whether regional latecomers suffer the domestically created ‘pollution haven’ effect through the interjurisdictional competition for polluted industries within China, or enjoy the spillover effect of nationwide progress in environmental management and technology, using the analytical framework of the environmental Kuznets curve. The study found that the regional latecomer's advantage was verified in the case of wastewater, while its disadvantage was identified in waste gas and solid waste. We speculate that the contrasting result on regional latecomer's effects between wastewater, waste gas, and solid waste comes from the difference in policy performances: the well-designed water pollution control may have regional latecomer's enjoy the spillover effect of nationwide progress, while the ineffective control of air and solid waste pollution may cause a ‘pollution haven’ effect through the interjurisdictional competition for polluted industries on regional latecomers.
