Avoiding a catastrophic climate-change event is a global public good characterized by several dimensions, notably heterogeneity between the parties involved. It is often argued that such heterogeneities between countries is a major obstacle to cooperative climate policy. We use a stylized game mimicking basic features of the climate-change dilemma...
This paper compares price stabilization (such as feed-in tariffs) versus quantity-based policies in supporting the deployment of renewable energy sources to produce electricity (RES-E) under uncertainty. We challenge a widespread view among RES-E supporters claiming that price stabilization provides more investment security and therefore triggers m...
We report the protocol relative to the experimental project "Sanctions and international interaction improve cooperation to avert climate change",which connected through the internet pairs of laboratories from Kiel and Bonn (Germany) and Moscow and Tomsk (Russia). The connection was realized through Z-Tree. Each research session comprised 24 partic...
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...
This paper centers on whether the timing of the regulator's commitment to an environmental policy affects the firms' behavior concerning the adoption of an advanced abatement technology. Our experimental design mimics an industry with small asymmetric polluting firms regulated by either emission taxes or permits. We compare two different timing reg...

Am 20. September hat die Bundesregierung die Einführung eines nationalen CO2-Preises
beschlossen. Sie hat sich dabei für eine Preisregulierung entschieden, die ab dem Jahr 2026
weitgehend durch eine Mengenregulierung ersetzt wird. Der vorliegende Artikel schlägt
vor, Preis- und Mengenziel von Anfang an zu kombinieren und so Planungssicherheit zu

We experimentally test the truth-telling mechanism proposed by Montero (2008) for eliciting firms' abatement costs. We compare this mechanism with two well-known alternative allocation mechanisms, free and costly allocation of permits at the Pigouvian price. Controlling for the number of firms and the firms' maximal emissions, we find that, in line...
Im Verkehrssektor sind die Emissionen in den letzten Jahren gestiegen statt gesunken. Schnelle Entscheidungen und innovative Mobilitätskonzepte sind notwendig, damit Städte klimafreundlicher werden können. Haben sich Kommunen aber einmal festgelegt, ist der Umstieg auf einen alternativen Ansatz mitunter schwierig und teuer – es können Pfadabhängigk...
We study differences in behavior across countries in a labor market context. To this end, we conducted a bilateral gift-exchange experiment comparing the behavior of subjects from five high-income OECD countries: Germany, Spain, Israel, Japan and the USA. We observe that in all countries, effort levels are increasing while rejection rates are decre...
This study investigates the impact of communication on outcomes in Cournot duopoly and triopoly experiments. Communication is implemented by two different devices, a ‘standardized-communication’ and a ‘free-communication’ device. Using both students and managers as subjects, we find that managers behave in a similar way under both communication dev...
Standard double auctions perfectly mimic the neoclassical idea about the functioning of markets. The efficiency of the market outcome and speed of adjustment towards equilibrium have been studied in the literature to validate economic expectations. However, only a few real world examples outside the financial sector exist. In 2000, Germany implemen...
The paper analyzes the relationship between CO2 mitigation policy and promotion policies designed to deploy renewable energy sources for electricity production (RES-E). If an emission cap is the only policy target, an optimal mix consisting of high and low carbon use of fossil fuels, deployment of RES-E, and energy savings can best be achieved by e...
Emissions trading has been established as an important instrument of pollution control in many world regions. However concerns have been raised whether or not emission-trading schemes may distort competition either on the permit market itself or on related output markets. In this paper we review tradable emission-allowance schemes with special refe...
We show that for a broad class of technologies the relationship between policy stringency and the rate of technology adoption is inverted U-shaped. This happens when the marginal abatement cost (MAC) curves of conventional and new technologies intersect, which invariably occurs when emissions are proportional to output and technological progress re...
We study optimal fishery management in an age-structured, bio-economic model where two age classes can be harvested independently. We show that the optimal amount of catch differs with age classes, and we derive conditions under which it is optimal to harvest only one age class. Our main policy implication is that optimal age-structured harvesting...
One key problem regarding the external validity of laboratory experiments is their duration: while economic interactions out in the field are often lengthy processes, typical lab experiments only last for an hour or two. To address this problem, we introduce novel internet treatments lasting more than a month, and we compare it to the corresponding...
We present a model of a multispecies fishery, and we show the following. (i) Consumer preferences for seafood diversity can trigger a sequential collapse of fish stocks under open‐access fishery. (ii) The stronger the preferences are for diversity, the higher is the need for coordinated multispecies regulation. (iii) Second‐best optimal management...
We study pure indirect reciprocity by setting up a modified dictator game with three players A, B, and C acting sequentially. Subject A takes a share of a pie and passes the rest to subject B, while B divides the rest between herself and C. We find that this consecutive three-person dictator game increases generosity compared with the traditional t...
In this paper we make use of a unique dataset collected in the central train station of Kiel, Germany. A group ticket is used by individual proposers who search for co-travelers to share the ride with shortly before the train departure. The bargaining behavior resembles the Ultimatum game to the extent that proposers request a fixed price for a sha...
We investigate the optimal exploitation of methane hydrates, a recent discovery of methane resources under the sea floor, mainly located along the continental margins. Combustion of methane (releasing CO2) and leakage through blow-outs (releasing CH4) contribute to the accumulation of greenhouse gases. A second externality arises since removing sol...
This article provides the main insights into the debate on instrument choice between price and quantity control instruments for emissions control. Price control refers to the emission taxes or charges. Quantity control mainly refers to the cap and trade. The focus within this theme is on imperfect information about abatement costs, resulting in the...
Many important environmental policies involve some combination of emission controls and ambient environmental quality standards, for instance SO2 emissions are capped under Title IV of the U.S. Clean Air Act Amendments while ambient SO2 concentrations are limited under National Ambient Air Quality Standards (NAAQS). This paper examines the relative...
Fish stocks can be considered as natural capital stocks providing harvestable fish. Fishing at low stock sizes means borrowing from the natural asset. While fishing a particular quantity generates immediate profits and income, an interest rate has to be paid in terms of foregone future fishing income, as the fish stock's reproductive capacity remai...
This paper presents an experimental investigation of environmental policy instruments on the incentives to adopt advanced abatement technology in tradable permit markets. Our design, based on Requate and Unhold (2001), involves an industry with small regulated asym- metric firms. We consider three auction-allocation policies: auctioning o permits t...
The question of whether alcohol and tobacco are consumed as complements or substitutes is crucial for determining the side-effects of anti-smoking policies. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco, and subsequently calculating cross-price effects. However, this traditional approach...
We study the impact of learning by doing, learning spill-overs, and imperfect competition in a model with two types of electricity producers, an oligopolistic sector of polluting fossil-fuel utilities and a competitive fringe of non-polluting generators of electricity from renewable energy sources (RES-E). Furthermore we consider an upstream indust...
Many environmental problems, notably arising from agriculture, can be classified as non-point source pollution problems. In this paper we present results of an experimental study on the performance of three mechanisms designed to deal with such problems: collective fining, random fining, and a tax-subsidy scheme. We find that the fining schemes ind...
This study extends a bilateral gift-exchange experiment by Clark et al. (2010). We investigate how the provision of either quantitative or qualitative information on the average wage paid in all worker–employer relationships impacts the wage set by employers and worker performance. We find that information on the average wage reduces (increases) bo...
We report on an experiment conducted to evaluate the effects of varying the way in which market information is presented to
participants in laboratory Cournot duopolies. We find that the most standard variations, which are the use of a profit table
or a profit calculator, yield indistinguishable performance. However, the addition of a best-response...
In this paper we survey recent developments on the incentives through environmental policy instruments to adopt advanced abatement
technology. We further investigate repercussions on R&D. First we study the case where the regulator makes long-term commitments
to policy levels and does not anticipate the arrival of new technology. We show that taxes...
This article reports results from Cournot duopoly and triopoly experiments with different subject pools: German students, Malaysian students and Malaysian managers. We find that Malaysian managers perform significantly more collusively than Malaysian students. We also find that country matters insofar as German students perform significantly more c...
The Common Fisheries Policy (CFP) of the European Union has neither lived up to its aim of enhancing the sustainability of fish stocks nor that of improving the economic competitiveness of the fishing industry. This paper discusses the failure of the CFP from a biological, economical, legal and political perspective.
This article discusses German and European climate policy, inquiring mainly whether the ambitious goals the EU has set itself can be achieved via the instruments presently employed for the purpose and whether these instruments are efficient. In particular we discuss shortcomings of the European emission trading system, we further level criticism at...
We report results from a Cournot triopoly experiment conducted with different subject pools: German students, Malaysian students, and Malaysian managers. We find that Malaysian students perform significantly more competitively than both Malaysian managers and German students. Moreover, the Nash equilibrium point quite accurately describes the behav...
This paper considers the performance of ambient environmental quality and emissions (effluent) policies in settings where the ability of the receiving environmental media to assimilate pollution is stochastic, for instance a river with variable streamflow. Our main findings are: (i) ambient environmental quality policies welfare dominate emission p...
This study investigates the impact of pre-play communication on the outcomes in Cournot duopoly and triopoly experiments, using both students and managers as subjects. Communication is implemented by two different devices, a 'standardized-communication' and a free-communication device. We find that the effect of communication on collusion is larger...
We present the results of a framed field experiment with Ethiopian farmers that use the mountain rain forest as a common pool resource. Harvesting honey causes damage to the forest, and open access leads to over-harvesting. We test different mechanisms for mitigating excessive harvesting: a collective tax with low and high tax rates, and a tax/subs...
The economic and environmental gains expected from particular environmental policies based on allowances trading programs depend on how they are specifically implemented in the field. In this paper we focus on a tradable permit program based on a double auction market combined with an industry structure that presents heterogeneity in conventional a...
We investigate optimal abatement strategies for cumulative and interacting pollutants. We show that different decay rates can cause non-monotonic behavior in the optimal paths of emissions, the aggregate level of pollution, and even the relative optimal price for emissions. This contrasts strikingly with the case of a single pollutant. The results...
Wenn das Bundesverfassungsgericht (BVG) am 9. Dezember 2008 sein Urteil darüber verkündet, ob die geltende gesetzliche Regelung zur Pendlerpauschale verfassungswidrig ist, dann steht ihre juristische Bewertung im Vordergrund. Aktuell werden die Aufwendungen der nicht-selbständigen Arbeitnehmer und der Selbständigen für Wege zwischen Wohnung und Arb...
The question of whether two drugs – namely alcohol and tobacco – are used as complements or substitutes is of crucial interest if side-effects of anti-smoking policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and subsequently calculating cross-price effects. However,...
We study long-term incentives for regulated polluting firms to invest in advanced abatement technologies when some new technology is available but even better technology is expected for the future. Firms can invest only once. We find that, depending on the cost of adoption, all possible investment patterns can occur in social optimum. Further, a re...
We study long-term incentives for polluting and regulated firms to invest in advanced abatement technologies, when some new technology is available but an even better technology will be expected in the future. Firms can invest only once. We find that depending on the adoption fixed costs all possible combinations of investment patters can occur in...
This paper presents a cost-benefit analysis of three different use systems for the remaining cloud forests in Ethiopia which at present are being depleted at a rate of 8% per year. These use systems are traditional conversion to crop land, sustainable management of the forest (e.g. by growing high-quality semi-forest coffee), and strict protection....
We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are qualitatively different for substitutes and complements. We...
We survey the theoretical literature on pollution-reducing and resource-saving technological progress, differentiating between microeconomic partial equilibrium models and endogenous growth models. The microeconomic models serve to investigate incentives to develop and adopt environmentally friendlier technologies under different policy tools, comm...

Corruption in the public sector erodes tax compliance and leads to higher tax evasion. Moreover, corrupt public officials abuse their public power to extort bribes from the private agents. In both types of interaction with the public sector, the private agents are bound to face uncertainty with respect to their disposable incomes. To analyse effect...
We modify the traditional dictator game by introducing 3 generations A, B and C. A takes an arbitrary share of a pie and passes the rest to B. B divides the rest of the pie between her and C. We flnd that this sequential dictator game increases generosity with respect to comparable traditional dictator games. Introducing a treatment with a social i...
Der Stern-Report, der vierte IPCC-Bericht der UNO und nicht zuletzt der extrem warme Winter 2006/07 haben die Klimaproblematik wieder in de Mittelpunkt des öffentlichen Interesses gerückt. Welchen Beitrag kann und sollte Deutschland zur Lösung des Weltklimaproblems leisten? Die Antwort von Sigmar Gabriel, Bundesminister für Umwelt, Naturschutz und...
Two practical environmental policy targets are to limit aggre- gate emissions across firms and to limit pollution concentrations in the receiv- ing environmental medium. Under circumstances characterized by stochastic environmental damages, for example the case of water pollution disposed into a river with variable seasonal streamflow, the choice b...
The question of whether two drugs – namely alcohol and tobacco – are used as complements or substitutes is of crucial interest if side-effects of anti-drug policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and subsequently calculating cross-price effects. However, thi...
In this paper I survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology. A main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control. Mor...
In July 2003 the European Parliament and the Council have started a new era of environmental regulation by establishing a nationwide open emission trading system for the European Union. In this article we firstly critically discuss the institutional rules set by the EU-directive. Secondly, we analyse consequences for the national allocation plans....
