Learning, Signaling, and Social Preferences in Public-Good Games
Provedor de dados: 7
Autores: Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Ahn, T. K.; Florida State University and Korea University; tahn@fsu.edu.
This study compares the empirical performance of a variety of learning models and theories of social preferences in the context of experimental games involving the provision of public goods. Parameters are estimated via maximum likelihood estimation. We also performed estimations to identify different types of agents and distributions of parameters. The estimated models suggest that the players of such games take into account the learning of others and are belief learners. Despite these interesting findings, we conclude that a powerful method of model selection of agent-based models on dynamic social dilemma experiments is still lacking.

Irrigation experiments in the lab: trust, environmental variability, and collective action

Research on collective action and common-pool resources is extensive. However, little work has concentrated on the effect of variability in resource availability and collective action, especially in the context of asymmetric access to resources. Earlier works have demonstrated that environmental variability often leads to a reduction of collective action in the governance of shared resources. Here we assess how environmental variability may impact collective action. We performed a behavioral experiment involving an irrigation dilemma. In this dilemma participants invested first into a public fund that generated water resources for the group, which were subsequently appropriated by one participant at a time from head end to tail end. The amount of resource...

Collective action and the risk of ecosystem regime shifts: insights from a laboratory experiment
Provedor de dados: 7
Autores: Schill, Caroline; The Beijer Institute of Ecological Economics, The Royal Swedish Academy of Sciences; Stockholm Resilience Centre, Stockholm University; caroline.schill@beijer.kva.se; Lindahl, Therese; The Beijer Institute of Ecological Economics, The Royal Swedish Academy of Sciences; Stockholm Resilience Centre, Stockholm University; therese.lindahl@beijer.kva.se.
Ecosystems can undergo regime shifts that potentially lead to a substantial decrease in the availability of provisioning ecosystem services. Recent research suggests that the frequency and intensity of regime shifts increase with growing anthropogenic pressure, so understanding the underlying social-ecological dynamics is crucial, particularly in contexts where livelihoods depend heavily on local ecosystem services. In such settings, ecosystem services are often derived from common-pool resources. The limited capacity to predict regime shifts is a major challenge for common-pool resource management, as well as for systematic empirical analysis of individual and group behavior, because of the need for extensive preshift and postshift data. Unsurprisingly,...

Introducing Ecological Dynamics into Common-Pool Resource Experiments
Provedor de dados: 7
Autores: Janssen, Marco A; School of Human Evolution and Social Change, Arizona State University; Marco.Janssen@asu.edu.
Case-study analysis shows that long-lasting social&amp;#8211;ecological systems have institutional arrangements regulating where, when, and how to appropriate resources instead of how much. Those cases testify to the importance of the fit between ecological and institutional dynamics. Experiments are increasingly used to study decision making, test alternative behavioral models, and test policies. In typical commons dilemma experiments, the only possible decision is how much to appropriate. Therefore, conventional experiments restrict the option to study the interplay between ecological and institutional dynamics.  Using a new real-time, spatial, renewable resource environment, we can study the informal norms that participants develop in an experimental...

Influence of     Crepidula fornicata     on suspended particle dynamics in coastal systems: a mesocosm experimental study
Provedor de dados: 5
Autores: Grasso, Florent; Carlier, Antoine; Cugier, Philippe; Verney, Romaric; Marzloff, Martin.
In coastal environments, strong feedback can exist between benthic fauna and sediment dynamics. Benthic populations can modify sediment dynamics through biofiltration and bioturbation, while hydro- and sediment dynamics directly determine local environmental conditions for benthic organisms. However, these complex feedbacks are difficult to study in situ. Here, we carried out mesocosm experiments to characterize the effects of a benthic species (the gastropod Crepidula fornicata) on mud dynamics under hydrodynamic conditions representative of their natural habitat. Different experimental tests related to the inclusion (or not) of dead or live crepidula reveal that biofiltration can increase particle settling up to 40%. Flocculation, which is strengthened...

Experimental ecology: A key to understanding fish biology in the wild
Provedor de dados: 5
Autores: Suquet, Marc; Rochet, Marie-joelle; Gaignon, Jean-louis.
Because of natural complexity, field studies are often inconclusive with regards to the ultimate cause of a given change observed in wild animal populations. As a consequence, there is scope to develop an Experimental Ecology Approach (EEA). In this paper, we favour the use of experimental ecology studies to evaluate the effects of environmental factors on fish biology. We identify the advantages of EEA: disentangling the effects of several factors and identifying their respective roles, generating artificial scenarios and increasing our capability to collect and analyse data. This study emphasises the constraints of this approach: fish biological performances may be altered by rearing conditions, by domestication and by the prevention of some behaviours....

An Experimental Analysis of Compliance in Dynamic Emissions Markets
Provedor de dados: 31
Autores: Stranlund,   John K.; Murphy,   James J.; Spraggon,   John M.
Two important design elements for emission trading programs are whether and to what extent firms are able to bank emissions permits, and how these programs are to be enforced. In this paper we present results from laboratory emissions markets designed to investigate enforcement and compliance when these markets allow permit banking.  Banking is motivated by a decrease in the aggregate permit supply in the middle of multi-period trading sessions. Consistent with theoretical insights, our experiments suggest that high permit violation penalties have little deterrence value in dynamic emissions markets, and that the main challenge of enforcing these programs is to motivate truthful self-reports of emissions.

Imperfect Enforcement of Emissions Trading and Industry Welfare: A Laboratory Investigation
Provedor de dados: 31
Autores: Stranlund,   John K.; Murphy,   James J.; Spraggon,   John M.
This paper uses laboratory experiments to investigate the performance of emission permit markets when compliance is imperfectly enforced. In particular we examine deviations in observed aggregate payoffs and expected penalties from those derived from a model of risk-neutral payoff-maximizing firms. We find that the experimental emissions markets were reasonably efficient at allocating individual emission control choices despite imperfect enforcement and significant noncompliance. However, violations and expected penalties were lower than predicted when these are predicted to be high, but were about the same as predicted values when these values were predicted to be low.  Thus, although a standard model of compliance with emissions trading programs tends to...

Analysis of the Environmental Effects of the Burning of the Straw for Energy Purposes
Provedor de dados: 111
Autores: Macak, Miroslav.
Long-term using of fossil fuels has caused global climatic changes. Using of the renewable energy sources based on the field crop biomass can be considered as a tool allowing compensating the negative consequences of the fossil fuels. Among different types of biomass based fuels the straw baled in the form of square bales plays an important role. Until now the research pays only small attention to the environmental effects related to the using of the straw for energy purposes.  The aim of the paper was to analyze the effect of moisture content of the straw used for energy purposes. The straw has been baled to the form of large square bales. The straw bales were burned in special boiler. The quality of incineration process was monitored for different straw...
