Past CO2 emissions cause cost and reduce wealth in the future. The present value of these costs measure the wealth borrowing from the future and countries differ considerably in their share and time profile of past CO2 emissions. Here we calibrate an integrated assessment model to data on past economic and climate development to estimate the social...
Chapter
Full-text available
The chapter assesses the role of nature's diverse values in supporting social-ecological transformations towards more just and sustainable futures. This is approached as a two-fold and mutually complementing task: a) assessing the diverse values that have been considered in developing and creating visions for, and scenarios of the future, particula...
Article
Full-text available
Small-scale fisheries often operate under conditions of regulated open access; that is, the fishery is subject to natural or regulatory constraints on fishing technology, including regulations of fishing gear and fishing practices, but typically there is no direct regulation of catches. We study how an increase in harvesting efficiency changes the...

We study optimal harvesting of a renewable resource with stochastic dynamics. To focus on the effect of risk aversion, we consider a resource user who is indifferent with respect to intertemporal variability. We find that a constant escapement strategy is optimal, i.e. the stock after harvesting is constant. Under common specifications of risk aver...

Full-text available
Historical patterns of the Eastern Baltic cod stock recruitment show a shift from a regime with high reproductive potential before the early 1980s to a regime with low reproductive potential since then. This shift can be attributed to increasingly unfavorable environmental conditions for cod reproduction at that time: critical salinity and oxygen l...
Article
Full-text available
The Baltic fisheries are in distress. In the Central Baltic, fisheries management is challenged by reduced cod stock productivity, and altered species interactions. Here, we use an age-structured, ecological–economic multispecies model, which includes latest biological and economic knowledge, to advance our understanding of optimal fisheries manage...
Article
Ecolabels are supposed to reduce the information asymmetry between producers and consumers, but they may also produce a warm glow of “green” behavior. We design discrete choice experiments to measure the relative importance of these motivations for choosing ecolabeled seafood products. We find that choice probability increases if the product carrie...

Radiation management (RM) has been proposed as a conceivable climate engineering (CE) intervention to mitigate global warming. In this study, we used a coupled climate model (MPI-ESM) with a very idealized setup to investigate the efficacy and risks of CE at a local scale in space and time (regional radiation management, RRM) assuming that cloud mo...

This paper introduces endogenous technological change in a Hotelling-Herfindahl model of natural resource use to study the recent developments in the U.S. natural gas industry. We consider optimal forward-looking technology investments, and study implications for the order of extraction of conventional and shale gas, and a backstop technology, and...
Article
Full-text available
Building on the epidemiological SIR model, we present an economic model with heterogeneous individuals deriving utility from social contacts creating infection risks. Focusing on social distancing of individuals susceptible to an infection we theoretically characterize the gap between private and social cost of contacts. Our main contribution is to...

Abstract Improving the health of coastal and open sea marine ecosystems represents a substantial challenge for sustainable marine resource management, since it requires balancing human benefits and impacts on the ocean. This challenge is often exacerbated by incomplete knowledge and lack of tools that measure ocean and coastal ecosystem health in a...

We study how income inequality affects the social value of a dynamic public good, such as natural capital. Our theory shows that both intra- and intertemporal inequality affect the social value of public natural capital. The direction and size of the effects are driven by the degree of substitutability between the public and private consumption goo...
Article
We develop a bioeconomic model to analyze the long-run supply of fish and find that steady-state supply can have multiple bends in an age-structured setting. We parameterize the model using data for the Eastern stock of Atlantic Bluefin tuna during the predominantly open access period (1950 to 2006). The numerical Bluefin supply curve bends backwar...

We characterize intertemporal utility functions over heterogeneous goods that feature (i) a constant elasticity of substitution between goods at each point in time and (ii) a constant intertemporal elasticity of substitution for at least one of the goods. We find that a standard, stationary intertemporal utility function is consistent with these tw...

This paper sets up a dynamic model to study the distributive effects of privatizing an open access resource. We show that with or without discounting, privatization is not always Pareto improving. We further derive conditions under which the poor are made worse off when private use rights are equally distributed compared to a situation with open ac...

Nature-based solutions to insurance are in high demand. We explore the idea that natural capital has an insurance value insofar as it can mitigate the effects of uncertainty on human well-being. We present a formal model that substantiates this claim. We propose a definition for the insurance value of natural capital for a stochastic and dynamic ec...

Understanding what determines the truth-telling of economic agents towards their regulator is of major economic importance from banking to the management of common-pool resources such as European fisheries. By enacting a discard-ban on unwanted fish-catches without increasing monitoring activities, the European Union (EU) depends on fishermen's tru...

Human-induced climate change such as ocean warming and acidification, threatens marine ecosystems and associated fisheries. In the Western Baltic cod stock socio-ecological links are particularly important, with many relying on cod for their livelihoods. A series of recent experiments revealed that cod populations are negatively affected by climate...

Improving fisheries management is a key challenge in addressing the United Nations Sustainable Development Goal 2 (Zero Hunger) and support Goals 1 (No Poverty) and 14 (Life Below Water). However, sustaining the ocean's living resources has important dimensions beyond food security, such as cultural values, which might be of equal importance in som...

Full-text available
We analyze the efficiency of urbanization patterns in a stylized dynamic model of urban growth with three sectors of production. Pollution, as a force that discourages agglomeration, is caused by domestic production. We show that cities are too large and too few in number in uncoordinated equilibrium if economic growth implies increasing pollution...

Full-text available
The behavior of a fishing fleet and its impact onto the biomass of fish can be described by a nonlinear parabolic diffusion–reaction equation. Looking for an optimal fishing strategy leads to a non-convex optimal control problem with a bilinear control action. In this work, we present such an optimal control formulation, prove its well-posedness an...
Article
Full-text available
We study under which conditions a ‘window of opportunity’ for a change from an overfishing situation, with high fishing effort, but low stocks and catches, towards sustainable fishery management arises. Studying the Eastern Baltic cod fishery we show that at very low stock sizes (as they prevailed in the early 2000s) all interest groups involved in...

Full-text available
Since January 2014, the reformed Common Fisheries Policy (CFP) of the European Union is legally binding for all Member States. It prescribes the end of overfishing and the rebuilding of all stocks above levels that can produce maximum sustainable yields (MSY). This study examines the current status, exploitation pattern, required time for rebuildin...
Article
Full-text available
We explore how the intertemporal distribution of well-being affects the social cost of carbon. In contrast to the literature that studies parameters of a particular social welfare function, such as the discount rate, we shift the focus and directly assume a parametric form for the intertemporal distribution of well-being. This has the advantage of...
Article
Understanding what influences the value of nature is crucial for informing environmental policy. From a sustainability perspective, economic valuation should not only seek to determine a society's willingness to pay for environmental goods to devise an efficient allocation of scarce resources, but should also account for distributional effects to e...
Article
Full-text available
Conservation of renewable natural resources and promotion of economic growth are both sustainable development goals. Here, we study the interdependency between economic growth, international trade, and the use of renewable natural resources—under alternative institutional settings of either open access or full property rights—in an endogenous growt...

Marine ecosystems evolve under many interconnected and area-specific pressures. To fulfil society's intensifying and diversifying needs while ensuring ecologically sustainable development, more effective marine spatial planning and broader-scope management of marine resources is necessary. Integrated ecological–economic fisheries models (IEEFMs) of...
Chapter
Reliable and sustainable fisheries management needs to take species interactions into account, as well as the multiple ecological, economic, or social needs. In the Baltic Sea, we used inter- and transdisciplinary approaches to explore different management objectives. The coupled ecological–economic fisheries model was able to address different eco...

viter la contestation d'acteurs aux objectifs divers et parfois contradictoires est un défi majeur pour le développement durable et pour l'identification de politique pour la biodiversité et les services éco-systémiques. De plus, respecter les seuils d'acceptation des différents acteurs indépendamment n'est pas suffisant parce que des interactions,...
Article
We study how rights-based resource management can trigger labor reallocation and development in a dual economy. Under open access, resource users may remain trapped in poverty. Regulation of resource use generates rents that can finance labor reallocation to resource-independent production. Transferability of harvest quotas broadens the scope for l...
