Isolating the climate change impacts on air-pollution-related-pathologies over central and southern Europe – a modelling approach on cases and costs
2019
Air pollution has important implications for human health and associated external costs to society and is closely related to climate change. This contribution tries to assess the impacts of present (1996-2015) and future (2071-2100 under RCP8.5) air pollution on several cardiovascular and respiratory pathologies and estimate the difference in the costs associated with these health impacts on the European population. For this, air quality data from the regional chemistry-climate modelling system of the Weather Research and Forecasting (WRF) model coupled with Chemistry (WRF-Chem) are used, together with some epidemiological information from the European Commission. The methodology considered…
Spatial Localization in Manufacturing: A Cross-Country Analysis
2009
This paper employs a homogenous firms' database to investigate industry localiza- tion in European countries. More specifically, we compare, across industries and countries, the predictions of two of the most popular localization indices, i.e., the Ellison and Glaeser index (Ellison and Glaeser, 1997) and the Duranton and Over- man index (Duranton and Overman, 2005). We find that, independently from the index used, localization is a pervasive phenomenon in all countries studied, but the degree of localization is very uneven across industries in each country. Furthermore, we find that the two indices significantly diverge in predicting the intensity of the forces generating localization with…
Morphological similarities between DBM and a microeconomic model of sprawl
2010
JEL classification : C61; C63; D62; R21; R40; International audience; We present a model that simulates the growth of a metropolitan area on a 2D lattice. The model is dynamic and based on microeconomics. Households show preferences for nearby open spaces and neighbourhood density. They compete on the land market. They travel along a road network to access the CBD. A planner ensures the connectedness and maintenance of the road network. The spatial pattern of houses, green spaces and road network self-organises, emerging from agents individualistic decisions. We perform several simulations and vary residential preferences. Our results show morphologies and transition phases that are similar…
Dynamic Models of International Environmental Agreements: A Differential Game Approach
2012
This article provides a survey of dynamic models of international environmental agreements (IEAs). The focus is on environmental problems that are caused by a stock pollutant as are the cases of the acid rain and climate change. For this reason, the survey only reviews the literature that utilizes dynamic state-space games to analyze the formation of international agreements to control pollution. The survey considers both the cooperative approach and the noncooperative approach. In the case of the latter, the survey distinguishes between the models that assume binding agreements and those that assume the contrary. An evaluation of the state of the art is presented in the conclusions along w…
Decisions, externalitats i economia pública en un context de localització
2009
In this paper, we propose a learning application of the theory of market failure as part of a degree in Economics. They are new contexts in which adapt existing knowledge. Even a small contribution from our clasrrom experience, we can say that one side is extremely motivating for students and the other opens a new methodological framework in which student participation in learning becomes crucial.
Justice et inégalités: un amendement à la théorie de John Rawls
1992
National audience; On se demande si les principes de justice de Rawls ne sont pas exagérément inégalitaires, malgré leur côté "juste". On examine donc ce qu'il advient de l'optimum de Rawls, le maximin, quand de l'aversion pour l'inégalité" apparaît. Le maximin consiste à se placer sur un certain point de la courbe d'efficience, en admettant une certaine dose d'inégalité, pourvu que l'on donne le maximum possible aux plus défavorisés. On tient compte d'externalités en reprenant la notion d'envie sous la forme d'une aversion pour l'inégalité, essentiellement de la part des plus défavorisés. On ne peut plus raisonner sur la courbe frontière des rémunérations possibles et on démontre la validi…
The impact of corruption on sport demand
2020
PurposeThe article presents an empirical analysis that evaluates the effects of a systemic corruption scandal on the demand in the short and the long run. In 2006, the Calciopoli scandal uncovered the match rigging in the Italian soccer first division. The exemplary sportive sanction of relegating the primary culprit to the second division imposed further negative externalities on the other clubs. Should we prefer the sportive sanction on the team or the monetary fines for the club?Design/methodology/approachWe estimated two log-linear models of the demand side (stadium attendance) using a fixed effect estimator, on two panel data set made of all the Italian soccer clubs in the first and se…
Prices and Pareto optima
2006
We provide necessary conditions for Pareto optimum in economies where tastes or technologies may be nonconvex, nonsmooth, and affected by externalities. Firms can pursue own objectives, much like the consumers. Infinite-dimensional commodity spaces are accommodated. Public goods and material balances are accounted for as special instances of linear restrictions.
Valuing the unmarketable: an ecological approach to the externalities estimate in fishing activities
2013
In a rapidly changing world, sustainability, if it can be said to exist at all, is concept that has attained mythic status, often pursued and rarely reached. In order to improve our capability to cope with environmental problems, adopting an Ecosystem Approach has been suggested. One of the major challenges in the implementation of this new paradigm relates to control of externalities. The recognition and quantification of externalities is often cast as valuing the unmarketable, and there are several approaches that have been proposed. Here, we analyze the opportunity to “feed” the economic valuation with ecological concepts. From an ecological perspective, the energy required to sustain a …
The marketplace of ideas and its externalities: Who pays the cost of online fake news?
2023
Since the nineteenth century, thanks to J.S. Mill, an argument against limiting the freedom of expression has been gaining ground, namely that the truth of an argument is the result of free competition between different ideas in a “marketplace of ideas” and that this competition can yield an approximate form of the truth or a robust argument. In this paper I will argue that Mill’s model of the marketplace of ideas is an “idealised” model because it assumes that there is a subject who seeks to know in a detached manner, without being influenced by his or her expectations, needs, ideologies, or biases. However, the metaphor of the marketplace of ideas is still relevant because it also harbour…
