Transparency and cooperation in repeated dilemma games: a meta study

We use data from experiments on finitely repeated dilemma games with fixed matching to investigate the effect of different types of information on cooperation. The data come from 71 studies using the voluntary contributions paradigm, covering 122 data points, and from 18 studies on decision-making in oligopoly, covering another 50 data points. We find similar effects in the two sets of experimental games. We find that transparency about what everyone in a group earns reduces contributions to the public good, as well as the degree of collusion in oligopoly markets. In contrast, transparency about choices tends to lead to an increase in contributions and collusion, although the size of this effect varies somewhat between the two settings. Our results are potentially useful for policy making, because they provide guidance on the type of information to target in order to stimulate or limit cooperation.     

Meeting the demand: An estimation of potential future greenhouse gas emissions from meat production

Current production processes for meat products have been shown to have a significant impact on the environment, accounting for between 15% and 24% of current greenhouse gas emissions. Meat consumption has been increasing at a fantastic rate and is likely to continue to do so into the future. If this demand is to be met, technology used in production in the form of Confined Animal Feeding Operations (CAFOs) will need to be expanded. This paper estimates future meat consumption and discusses the potential aggregate environmental impact of this production if the use of CAFOs is expanded. I first separate meat into beef, chicken and pig products and estimate the elasticities associated with each product in order to forecast the world demand for meat. Using research on the environmental impact of food production in the US, which uses one of the most efficient CAFO processes in the world, I then calculate the total potential greenhouse emissions of this meat production and discuss the impact of these consumption patterns. I find that, under an expanded CAFO system, meat production in the future will still be a large producer of greenhouse gases, accounting for up to 6.3% of current greenhouse gas emissions in 2030.     

A Procedure for Negotiating Pollution Reduction under Information Asymmetry. Surface Water Quality Case

This paper considers an alternative approachto surface water quality management whensociety is faced with the need to reduce waterpollution in a region with a complicatedregulatory environment. The paper is focusedon a specific kind of negotiation betweenpolluters and an authority, leading toresolution of the problem when there is theinformation asymmetry between the authorityand the polluters, i.e., the true pollutionabatement costs are known to the pollutersonly. This paper reports a laboratory experimentalcase prepared at the Department ofEnvironmental Economics, the University ofEconomics in Prague. The comparison withtheoretical computed first-best results underconditions of full information is included.Political and economic aspects of thesuggested approach are also discussed.     

2. The Democratic Peace Myth: From Hiroshima to Baghdad

This paper examines the ideal of the democratic peace and the recent misuse of this ideal in the war on terrorism. It argues against the idea that aggressive military force can be employed to bring about the ideal of the democratic peace. By looking at John Stuart Mill's utilitarian justification of benevolent despotism for "barbarians," it examines how idealism can lead to a defense of aggressive intervention. And it considers how idealistic zeal can lead to violations of just war principles, as in the case of Hiroshima. It concludes by arguing that Kant's deontological approach is better. Kant provides us with a reason to hope that as democracy spreads, peace will spread as well. But Kant also prohibits us from using force to actualize this ideal.     

The Effect of Organic Food Labels on Consumer Attention

This paper aims to reveal consumer perceptions of organic food with a special emphasis on the labelling of organic products. The objectives were to find out, whether or not a significant difference between men´s and women´s perception existed. Two groups (88 subjects in the experimental group, 59 subjects in the control group) were shown various food labels; with organic product labelling (experimental) and without (control). Results suggest the importance of organic labelling using eye-tracking data and additional in-depth interviews to discover the importance of the labelling for participants. Based on eye-tracking data, the greatest visual attention was paid to product brand, graphic elements and organic labelling claims with additional information, such as a quantity or flavour, also being important. Additional in-depth interviews discovered that labelling, particularly of the origin, is important for most consumers. Contrary to what was expected, eye-tracking showed very little difference in the perception of organic product labelling based on gender. Although organic food is being purchased by more people, 50% of participants mentioned, during interviews, that they buy organic food only occasionally. The combination of eye-tracking and in-depth interviews shows that organic product labelling can play a role in decision-making, but regardless 27% of participants do not care about the organic quality labels or don’t pay attention to them.
