This paper contains a critical assessment of the claim that NNP can be used for welfare comparisons. The analysis assumes that national accounts are comprehensive (in particular ‘greened’ by taking into account environmental amenities and natural resource depletion), but does not assume optimal resource allocation. The general conclusion is that greater NNP corresponds to welfare enhancement only if net investment flows are revalued. Real utility-NNP and real measurable NNP made comparable across time by means of a consumer price index allow for such revaluation, and thus indicate welfare improvement.

Genuine saving is a measure of net investment in produced, natural and human capital. It is a necessary condition for weak sustainable development that genuine saving not be persistently negative. However, according to data provided by the World Bank, resource-rich countries are systematically failing to meet this condition. Alongside the well-known resource curse on economic growth, resource abundance might have a negative effect on genuine saving. In fact, the two are closely related, as future consumption growth is limited by insufficient genuine saving now. In this paper, we apply the most convincing conclusion from the literature on economic growth – that it is institutional failure that depresses growth – to data on genuine saving. We regress gross and genuine saving on three indicators of institutional quality in interaction with an indicator of resource abundance. The indicators of institutional quality are corruption, bureaucratic quality and the rule of law. We find that reducing corruption has a positive impact on genuine saving in interaction with resource abundance. That is, the negative effect of resource abundance on genuine saving is reduced as corruption is reduced.

Gold is frequently mined in rainforests that can provide either gold or forest benefits, but not both. This conflict in resource use occurs in Ghana, a developing country in the tropics where the capital needed for mining is obtained from foreign direct investment (FDI). We use a dynamic model to show that an ad valorem severance tax on gross revenue can be used to internalize environmental opportunity costs. The optimal tax must equal the ratio of marginal benefits from forest use to marginal benefits from gold extraction. Furthermore, the tax should increase (decrease) when adjusted net return on all other assets in the economy is higher (lower) than the growth in the price of gold. Empirical results suggest that the 3 per cent tax rate currently used in Ghana is too low to fully represent the external cost of extraction (i.e., lost forest benefits).

In the framework of the Harris–Todaro model we introduce a production–production externality and assume that the activity in the urban sector negatively affects (pollutes) the rural sector. As a means of reducing pollution a tax is imposed on the production of the polluting sector and the distributional and employment effects, as well as the national income aspects of such a tax, are explored. We take two versions of the Harris–Todaro model, the short run, where only labour is mobile between the rural and the urban sector, and the longer run, where all factors of production are intersectorally mobile. Our findings indicate that taxation will reduce pollution, may favour employment in the rural sector, and under certain conditions will also reduce unemployment, particularly in the longer run. National income will be generally enhanced if the share of the agricultural output in national income is higher than the share of manufactures.

Environmental conservation requires society to consider the trade-off between allocating resources to productive activities and pollution control activities. Therefore, it is informative to measure the effect of environmental regulations on firms' productivity. This paper attempts to estimate the impact of environmental regulations on Korean manufacturing industries. Despite being key inputs in the manufacturing process, raw materials have often been excluded from the cost function due to the lack of price data. A restricted cost function is used to improve the reliability of parameter estimates. Empirical results indicate that environmental regulations caused a 12 percent decline in the average annual rate of productivity growth over the period 1982–93.

Mumbai, the largest metropolitan city in India, generated 6,256 tons of waste per day in 2001. It is the responsibility of the Municipal Corporation of Greater Mumbai (MCGM) to provide Municipal Solid Waste (MSW) management services; however, the MCGM is not able to handle the increasing quantity of waste. As a result, waste litters all over the place giving rise to health and environmental problems. Hence, there is a need to involve private sector and community participation in waste management. In this paper, a linear programming model is developed to integrate different options and stakeholders involved in MSW management in Mumbai. Various economic and environmental costs associated with MSW management are taken into consideration while developing the model.

The effects of economic development on the exploitation of renewable resources are investigated in settings where property rights are ill defined or not enforced. This paper explores potential conservation implications from labor and product market developments, such as enhanced transportation infrastructure. A model is developed that predicts individual fish catch per unit effort based on characteristics of individual fishermen and the development status of their villages. The econometric model is estimated using data from a cross-sectional household survey of artisanal coral reef fishermen in Minahasa, Indonesia, taking account of fishermen heterogeneity. Variation across different villages and across fishermen within the villages is used to explore the effects of development. Strong evidence is found for the countervailing forces of product and labor market effects on the exploitation of a coral reef fishery.

This paper estimates maximum sustainable yield and maximum economic yield from Schaefer and Fox surplus production bioeconomic models to find evidence of biological and economic overfishing, and their consequences in Gulf of Thailand demersal fisheries. The paper examines alternative policy instruments to reduce overfishing. The discussion emphasizes strengthening fishery management for implementing limited access, and a combination of co-management, and decentralization of fisheries management. The use of license fees that serves as a double dividend tax to reduce fishing effort and fund monitoring and enforcement has been proposed as one of the possible economic instruments.
