This paper explores the economic feasibility of secondary forest regeneration and conservation as an alternative in the campaign addressing the problem of global warming. Detailed measurements of tropical secondary forests over time, in different ecological zones of Costa Rica, are used to evaluate carbon storage models. The paper addresses key issues in the international discussion about cross- and within-country compensation for carbon storage services and illustrates a method to compute/predict their economic value over time under a variety of scenarios. The procedure is applicable to other developing countries where secondary forest growth is increasingly important.

We estimate a hedonic-pricing model using geo-coded farmland-transaction data from the Campine region, situated in the north-east of Belgium. Unlike previous hedonic studies, we use the method of unconditional quantile regression (Firpo et al., in Econometrica 77(3):953–973, 2009). An important advantage of this new method over the traditional conditional quantile regression (Koenker and Bassett, in Econometrica 46(1):33–50, 1978) is that it allows for the estimation of potentially heterogeneous effects of cadmium pollution along the entire (unconditional) distribution of farmland prices. Using a threshold specification of the hedonic-pricing model, we find evidence of a U-shaped valuation pattern, where cadmium pollution of the soil has a negative and significant impact on prices only in the middle range of the distribution, insofar as cadmium concentrations are above the regulatory standard of 2 parts per million for agricultural land. Results obtained from a probit model to classify land plots into different price segments further suggest that the heterogeneous impact of soil pollution on price can be directly related to the variety of amenities that farmland provides.

The use of individual transferable quotas in fisheries has been considered an opportunity to achieve a given total allowable catch with a maximum social benefit. One of the assumptions used in obtaining that result is that the system is in perfect compliance. The presence of violations and the need for enforcement of tradable property rights systems in fisheries has not received much attention in the literature. The incidents of non-compliance, however, may affect the performance of transferable property rights-based fisheries in unexplored ways. In this paper, we adapt previous literature on enforcing emissions trading programs to analyze a positive model of fisherman behavior that operates under a perfectly competitive individual transferable quota system, while recognizing the opportunities for violations of quota holdings, given incomplete enforcement. Considering a poorly enforced, individual transferable quota system we are able to obtain a number of implications for the current and future equilibrium of the quota market, the time paths of the fishery, and the proper design of a policy rule on total allowable catch (TAC).

This paper re-examines the openended/dichotomous choice question in the lab. It hasearlier been suggested that the dichotomous choiceformat suffers from anchoring and yea-saying.Comparing actual economic commitments for a privategood with a significant market value, we cannot rejectthe null hypothesis of equal WTP for the two formats.We conclude that problems with DC might be due toissues of how the survey is framed, not the DCquestion itself.

Both economic theory and psychological research indicate that benefit functions for reductions in health risk exposures may be conditional on current exposures. Using nitrates found in household wells, it is demonstrated that perceptions of health risks across exposure levels are affected by the individual's current exposure level, thus providing support for a conditional benefits function approach. Functions of conditional incremental benefits are estimated from a contingent valuation study of households that had been informed of their water test results. Incremental benefits reach a peak at an intermediate level of nitrates and then decline. Possible explanations for this non-convexity are provided.

This paper uses a vote-counting procedure to estimate the probability density function of the total economic impact as a parabolic function of global warming. There is a wide range of uncertainty about the impact of climate change up to 3°C, and the information becomes progressively more diffuse beyond that. Warming greater than 3°C most likely has net negative impacts, and warming greater than 7°C may lead to a total welfare loss. The expected value of the social cost of carbon is about $29/tC in 2015 and rises at roughly 2% per year.

Two new important developments in environmental and resource economics is presented—non convex dynamics of ecosystems and wealth as an indicator of sustainable development. Non convex dynamics imply existence of resilience, that is the robustness of systems to withstand exogenous perturbations. Resilience can be regarded as an insurance against flips of the system into different basins of stability. Sustainable development, according to the Bruntland report, is the provision of productive resources to future generations to make it possible for them to live as well as the present generation. Thus, the value of changes in productive assets is therefore an index of whether an economy is on a sustainable path or not. Resilience can be regarded as one such productive asset and the paper discusses how one can define the value of this asset.

Shared fish stocks migrate across borders between different countries’ exclusive economic zones. This paper discusses the individual rationality of fish-sharing agreements based on the zonal attachment of such stocks. Three types of migrations are considered: (i) a common stock that grows and reproduces and is then distributed in given proportions between two countries’ zones at the beginning of each fishing season; (ii) sub-stocks that breed and grow independently in their separate zones but spill over between zones according to relative abundance; (iii) a stock that grows and breeds in one country’s zone but migrates into the zone of another if it exceeds a certain size. It is shown that in all these cases the minor partner in a fish-sharing agreement may not have an incentive to cooperate unless he gets a larger share of the cooperative profits than that corresponds to his share of the stock. This is particularly likely to happen when the unit cost of fish does not depend on the stock. An exception could occur if stock migration depends on the stock level; the major partner could then keep the entire stock by fishing it down to a critical level.

One of the recurring themes in the sustainability literature has been the extent to which a loss of natural capital can be made up for in welfare terms by an increase in other forms of capital. This issue was raised early on in the debate on sustainability by Pearce and has never really been resolved. This paper is an empirical attempt to measure the degree of substitutability between different forms of capital. A nested CES production function is used to allow flexibility in the estimated elasticities of substitution. Also, within this specification, natural resources and other inputs are combined in different levels of the function, thus allowing for different levels of substitutability. Institutional and economic indicators are also incorporated in the production function estimated. Results show that the elasticities derived from functions involving land resources were generally around one or greater, implying a fairly high degree of substitutability. Furthermore, changes in trade openness and private sector investment have a statistically significant and direct relationship on the efficiency of production and hence on income generation. No statistically significant relationship between income and any of the institutional indicators was found.
