Standard of Living

Abstract: Amartya Sen reconsiders the idea of ‘the standard of living’. He rejects the more conventional economic interpretations in terms of ‘unity’ and of wealth or ‘opulence’, and suggests an interpretation in terms of the ‘capabilities and freedoms’ that states of affairs do or do not allow. His argument is conceptual, but it refers to a wide range of examples. In elaborations of it, John Muellbauer explains how parts of it might be applied; Ravi Kanbur discusses the difficulties raised by choice ex ante, under uncertainty, and choice ex post; Keith Hart discusses the ways in which one might think about living standards in societies in which there is a substantial amount of what he calls ‘self provisioning’ outside the market; and Bernard Williams reflects on some of the moral and political implications of Sen’s argument. There is a bibliography of most of the more important works on the subject. The book will be of interest to economists, sociologists, students of development and moral and political philosophers; it will also be of interest to those concerned with public policy.

Why exactly is commitment important for rationality

Abstract: Gary Becker and others have done important work to broaden the content of self interest, but have not departed from seeing rationality in terms of the exclusive pursuit of self-interest. One reason why committed behavior is important is that a person can have good reason to pursue objectives other than self interest maximization (no matter how broadly it is construed). Indeed, one can also follow rules of behavior that go beyond the pursuit of one's own goals, even if the goals include non-self-interested concerns. By living in a society, one develops possible reasons for considering other people's goals as well, which takes one beyond an exclusive concentration on one's own goals, not to mention the single-minded pursuit of one's own self interest. The recognition of other people's goals may be a part of rational thought. If rational behavior may depart from the relentless pursuit of one's own goals, commitment has to be important in a theory of rationality. Furthermore, seeing the role of commitment in human behavior can have explanatory importance in allowing us to understand behavior patterns that are hard to fit into the narrow format of contemporary rational choice theory. Commitment is, thus, important both for practical reason and for causal explanation.

Sraffa, Wittgenstein y Gramsci

Abstract: Two distinct but interrelated issues are investigated here The first concerns Sraffa's critical role in contemporary philosophy through his pivotal influence on Wittgenstein The intellectual origins of this profound influence can be traced to the philosophical interests of the activist political circle in Italy (clustered around the journal L'Ordine Nuovo) to which both Sraffa and Antonio Gramsci belonged The second inquiry concerns the influence of Sraffa's philosophical views on his economics Sraffa's economic contributions can be much better understood by paying attention to the way Sraffa changed the nature of the questions asked, rather than seeking different answers to already established questions

On Happiness and Human Potentials: A Review of Research on Hedonic and Eudaimonic Well-Being

Abstract: ▪ Abstract Well-being is a complex construct that concerns optimal experience and functioning. Current research on well-being has been derived from two general perspectives: the hedonic approach, which focuses on happiness and defines well-being in terms of pleasure attainment and pain avoidance; and the eudaimonic approach, which focuses on meaning and self-realization and defines well-being in terms of the degree to which a person is fully functioning. These two views have given rise to different research foci and a body of knowledge that is in some areas divergent and in others complementary. New methodological developments concerning multilevel modeling and construct comparisons are also allowing researchers to formulate new questions for the field. This review considers research from both perspectives concerning the nature of well-being, its antecedents, and its stability across time and culture.

Agricultural sustainability and intensive production practices

Abstract: A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.

Dynamics of dark energy

Abstract: We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent progress made towards understanding the nature of dark energy. We review the observational evidence for the current accelerated expansion of the universe and present a number of dark energy models in addition to the conventional cosmological constant, paying particular attention to scalar field models such as quintessence, K-essence, tachyon, phantom and dilatonic models. The importance of cosmological scaling solutions is emphasized when studying the dynamical system of scalar fields including coupled dark energy. We study the evolution of cosmological perturbations allowing us to confront them with the observation of the Cosmic Microwave Background and Large Scale Structure and demonstrate how it is possible in principle to reconstruct the equation of state of dark energy by also using Supernovae Ia observational data. We also discuss in detail the nature of tracking solutions in cosmology, particle physics and braneworld models of dark energy, the nature of possible future singularities, the effect of higher order curvature terms to avoid a Big Rip singularity, and approaches to modifying gravity which leads to a late-time accelerated expansion without recourse to a new form of dark energy.
