Climate change impacts and market driven adaptation: The costs of inaction including market rigidities
No full textIn this paper we present a simple impact assessment exercise conducted with a
CGE model with two purposes. Firstly, we address a specific criticism raised
against IAMs: that of “overly optimistic” representation of adaptation processes
that brings, as a consequence, the implicit conclusion of a tendency to
underestimate climate change damages. We show that introducing rigidities in
adaptation processes the general results of the economic damage assessment
performed do change, but not substantively. We conclude that although a more
difficult adaptation increases as expected the damages (in our specific case,
globally by 20%, but at high temperature levels), this is not sufficient to drastically
change the overall picture. On the one hand this highlights robustness of the
results obtained with respect to adaptation processes. On the other hand, it shows
that the autonomous market adaptation mechanisms embedded in CGE models
explain only marginally low climate change costs. These are in fact due to
omission of other impacts because of their proven difficulty to be modelled, such
as: extreme events, damages due to ecosystem services’ losses, as well as major
disruptions due to the existence of tipping points.
Secondly, we also verify whether the assessments performed with CGE models
produce lower climate-change cost estimates than IA models using reduced-form
climate change damage functions. We show that, in fact, when the same impact
categories are considered across the two methodologies, damage estimates do not
differ significantly at the global level
Climate Change Feedback on Economic Growth: Explorations with a Dynamic General Equilibrium Model
Full text linkHuman-generated greenhouse gases depend on the level of economic activity. Therefore, most climate change studies are based on models and scenarios of economic growth. Economic growth itself, however, is likely to be affected by climate change impacts. These impacts affect the economy in multiple and complex ways: changes in productivity, resource endowments, production and consumption patterns. We use a new dynamic, multi-regional Computable General Equilibrium (CGE) model of the world economy to answer the following questions: Will climate change impacts significantly affect growth and wealth distribution in the world? Should forecasts of human-induced greenhouse gases emissions be revised, once climate change impacts are taken into account? We found that, even though economic growth and emission paths do not change significantly at the global level, relevant differences exist at the regional and sectoral level. In particular, developing countries appear to suffer the most from climate change impacts.Computable General Equilibrium Models, Climate Change, Economic Growth
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Micro-macro feedback links of agricultural water management: Insights from a coupled iterative positive Multi-Attribute Utility Programming and Computable General Equilibrium model in a Mediterranean basin
No full textMost water conservation policies will target agriculture, the largest human consumptive use and that concentrating the marginal (i.e. least productive) uses of the resource. Adaptation to irrigation rationing policies at the micro level will have an impact on agricultural outputs and propagate to the rest of the economic sectors at a regional and supra-regional (macro) scale. As the economy transitions towards new equilibrium commodity prices, the relevant prices for agriculture will change and this will in turn affect irrigators' decisions. This paper proposes an iterative coupling between a decentralized, non-parametric Positive Multi-Attribute Utility Programming representation of irrigators and a regionally-calibrated Computable General Equilibrium model to assess interlinkages (i.e. two-way feedbacks) between the micro- and macro-economy. Results from an application to irrigation water charges in the Murcia Region in Spain show that the coupled micro-macro model yields lower abatement costs as compared to the stand-alone micro model

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
