Interpersonal interaction in public goods contexts is very different in character to its depiction in economic theory, despite the fact that the standard model is based on a small number of apparently plausible assumptions. Approaches to the problem are reviewed both from within and outside economics. It is argued that quick fixes such as a taste for giving do not provide a way forward. An improved understanding of why people contribute to such goods seems to require a different picture of the relationships between individuals than obtains in standard microeconomic theory, where they are usually depicted as asocial. No single economic model at present is consistent with all the relevant field and laboratory data. It is argued that there are defensible ideas from outside the discipline which ought to be explored, relying on different conceptions of rationality and/or more radically social agents. Three such suggestions are considered, one concerning the expressive/communicative aspect of behaviour, a second the possibility of a part‐whole relationship between interacting agents and the third a version of conformism.

Climate change scholars generally urge that CO2emissions need to be cut rapidly if we are to avoid dangerous risks of climate change. However, climate change mitigation policies are widely perceived to have regressive effects — that is, putting a higher financial burden as a proportion of household income on poor than on rich households. This is one of several major barriers to the adoption of effective mitigation policies. They would also have considerable social justice implications requiring significant welfare state responses. We assess the claim that climate change policies have regressive effects by comparing different types of mitigation policies. We will argue that many of these are indeed likely to have regressive distributional implications but that there are several policy options to counteract regressive effects.

"Since the 1980s, there has been explosive growth in the use of experimental methods in economics, leading to exciting developments in economic theory and policy. Despite this, the status of experimental economics remains controversial. In Experimental Economics, the authors draw on their experience and expertise in experimental economics, economic theory, the methodology of economics, philosophy of science, and the econometrics of experimental data to offer a balanced and integrated look at the nature and reliability of claims based on experimental research. The authors explore the history of experiments in economics, provide examples of different types of experiments, and show that the growing use of experimental methods is transforming economics into a genuinely empirical science. They explain that progress is being held back by an uncritical acceptance of folk wisdom regarding how experiments should be conducted, a failure to acknowledge that different objectives call for different approaches to experimental design, and a misplaced assumption that principles of good practice in theoretical modeling can be transferred directly to experimental design. Experimental Economics debates how such limitations might be overcome, and will interest practicing experimental economists, nonexperimental economists wanting to interpret experimental research, and philosophers of science concerned with the status of knowledge claims in economics." --Amazon.com
