Two Sided Markets

Many questions in economics can be fruitfully analyzed in the framework of matching models. Until recently, empirical work has lagged far behind theory in this area. This review reports on recent developments that have considerably expanded the range of matching models that can be taken to the data. A leading theme is that in such two-sided markets, knowing the observable characteristics of partners alone is not enough to credibly identify the relevant parameters. A combination of richer data and robust, theory-driven restrictions is required. We illustrate this on leading applications. (JEL C57, C78)

Abundant Data

Abundant data has led to new opportunities for empirical auctions research in recent years, with much of the newest work on auctions of multiple objects, including: (1) auctions of ranked objects (such as sponsored search ads), (2) auctions of identical objects (such as Treasury bonds), and (3) auctions of dissimilar objects (such as FCC spectrum licenses). This paper surveys recent developments in the empirical analysis of such auctions. (JEL D44, H82)

This is the second edition of the first comprehensive textbook about the measurement and valuation of health benefits for economic evaluation. The National Institute for Health and Care Excellence (NICE) and similar agencies around the word require cost-effectiveness evidence in the form of incremental cost per quality-adjusted life year (QALY) in order to make comparisons across competing demands on resources, and this has resulted in an explosion of theoretical and empirical work in the field. This book addresses the theoretical and practical considerations in the measurement and valuation of health benefit with empirical examples and applications to help clarify understanding and make relevant links to the real world. It includes a glossary of key terms and provides guidance on the use of different methods and instruments. This updated edition provides an-up-to date review of the theoretical basis of the QALY; the definition of health; the techniques of valuation (including ordinal); the modelling of health state values (including mapping between measures); a detailed review of generic preference-based measures and other instruments for obtaining health state utility values (with recent developments); cross-cultural issues (including the disability-adjusted life year); the aggregation of QALYs; and the practical issues surrounding the use of utility values in cost-effectiveness models. The book concludes with a discussion on the way forward in light of the substantial methodological differences, the role of normative judgements, and where further research is most likely to take forward this fascinating component of health economics.

Emotion Concepts

Emotion concepts are important. They help us to understand, experience and predict human behaviour. Emotion concepts also link the realm of the abstract with the realm of bodily experience and actions. Accordingly, the key question is how such concepts are created, represented and used. Embodied cognition theories hold that concepts are grounded in neural systems that produce experiential and motor states. Concepts are also contextually situated and thus engage sensorimotor resources in a dynamic, flexible way. Finally, on that framework, conceptual understanding unfolds in time, reflecting embodied as well as linguistic and cultural influences. In this article, we review empirical work on emotion concepts and show how it highlights their grounded, yet dynamic and context-sensitive nature. The conclusions are consistent with recent developments in embodied cognition that allow concepts to be linked to sensorimotor systems, yet be flexibly sensitive to current representational and action needs. This article is part of the theme issue ‘Varieties of abstract concepts: development, use and representation in the brain’.

Multidisciplinary Teamwork

This chapter describes philosophical and empirical work underpinning recent developments in values-based mental health assessment culminating in the 3 Keys to a Shared Approach, a UK-based project co-produced between service users and providers. Three aspects of values-based mental health assessment are described: person-centered, multidisciplinary, or strengths-based assessment. The central role of values in person-centered assessment is shown through the story of a real (biographically disguised) person and the interpretation of his story drawing on diagnostic manuals such as the DSM. Philosophical value theory suggests that values in psychiatric diagnosis reflect the diversity of our values as unique individuals. This diversity is addressed by values-based practice. The contribution of multidisciplinary teamwork to values-based assessment is then outlined as derived from the Models Project. Finally, the 3 Keys Project is described, concluding by pointing to the wider significance of the Project for mental health practice as a whole.

This paper reviews recent developments in the study of the so-called ‘double dividend’, i.e. the possibility of improving the environment and, at the same time, reducing the distortions of the tax system through revenue-neutral green taxes. The main goal of the analysis is to identify the relationship between the modeling strategy and the double dividend results. Recent modeling advances are considered at both the theoretical and the empirical levels. In particular, we note that the most significant theoretical advances have been made in the direction of allowing for imperfectly competitive markets, especially the market for labor. At the same time, we argue that empirical work, particularly on the ‘employment double dividend’, is still relatively scant and that much more needs to be done both in the direction of more realistic empirical models and of an extended sensitivity analysis of the main findings.

Shed Light

Drawing on a new materialist approach, this article discusses the concepts of the virtual and virtual topology, and their fruitfulness for historians' empirical work. It starts by following Gilles Deleuze's argument that the virtual, the transformative potential of the real, has to be distinguished from the possible, which is merely an imagined double of the given world. Embracing this premise, the article shows the potential of virtual topology to shed light on the transformation of a network in the past. It suggests that history is not only about actual and stable things, it is also a site of becomings. This idea is elaborated through an analysis that focuses on the changes in the nineteenth-century Finnish press. The virtual as a theoretical concept is combined with the methodological opportunities offered by recent developments in the digital humanities, in this case, text reuse detection.

Strength Effect

How does retrieval take place in recognition memory? A number of computational models have been developed that posit that recognition operates by a process of global matching, wherein the cue is compared to each stored memory. These cue-to-memory similarities are then aggregated to produce an index of the global similarity between the cue and the contents of memory which can then be subjected to a decision process. In this chapter, we describe a.) the theoretical rationale and successes of such models, such as their accounts of similarity and list-length effects and generalization to multiple memory tasks, b.) challenges and hurdles they have experienced, including the null list-strength effect, the mirror effect, and the extralist feature effect, and c.) recent developments, such as extensions to predictions about response latency, sources of interference outside of the study list, and integration of more realistic representations.
