    En els debats sobre política mediambiental, la necessitat d'eliminar les subvencions mediambientalment nocives ha rebut poca atenció. Aquestes subvencions solen augmentar la grandària i la intensitat de la contaminació de les activitats econòmiques, sovint sense una clara compensació dels beneficis socials. L'impacte ambiental de les subvencions directes, o en el pressupost, ha estat àmpliament reconegut. Però les subvencions indirectes o fora de pressupost (no visibles en els pressupostos del govern) són almenys igual d'importants. La investigació realitzada sobre aquest tema és escassa, però aquest estudi mostra els resultats de les emissions de gasos d'efecte hivernacle (GEH) i dels acidificantes derivats de les subvencions fora de pressupost als Països Baixos i, en particular, mostren que els subsidis en l'agricultura, l'energia i els transports contribueixen de manera important a les emissions de GEH. Una política climàtica eficaç, per tant, ha de considerar l'eliminació de les subvencions fora de pressupost.En los debates sobre política medioambiental la necesidad de eliminar las subvenciones medioambientalmente dañinas ha recibido poca atención.

Such subsidies typically increase the size and pollution intensity of economic activities, often without clear, compensating social benefits. The environmental impact of direct or on-budget subsidies has been well recognized. Indirect or off-budget subsidies, not visible in government budgets, are at least as important. Research on this topic is scarce. This research reports findings on greenhouse gas (GHG) and acidifying emissions arising from off-budget subsidies in the Netherlands and show that subsidies particularly in agriculture, energy and transport contribute importantly to GHG emissions. Effective climate policy therefore needs to consider removal of off-budget subsidies

    Abolishing GDP

    Get PDF
    Expectations and information about the growth of GDP per capita have a large influence on decisions made by private and public economic agents. It will be argued here that GDP (per capita) is far from a robust indicator of social welfare, and that its use as such must be regarded as a serious form of market and government failure. This article presents an update on the most important criticisms of GDP as an indicator of social welfare and economic progress. It further examines the nature and extent of the impact of GDP information on the economy, revisits the customary arguments in favour of the GDP indicator, and critically evaluates proposed alternatives to GDP. The main conclusion is that it is rational to dismiss GDP as an indicator to monitor economic progress and to guide public policy. As is clarified, this conclusion does not imply a plea against growth, innovation or national accounting

    A procedure for globally institutionalizing a 'beyond-GDP' metric

    Altres ajuts: Acord transformatiu CRUE-CSICUnidad de excelencia María de Maeztu CEX2019-000940-MIf governments are serious about meeting environmental and social goals, they should overcome dominance of the GDP indicator in political discourse. Institutionalizing a beyond-GDP metric would be an essential step, in interaction with a shift in the direction of an "agrowth" paradigm. For a significant step forward, a permanent UN panel could be charged to explore the options and prepare a metric for global implementation. This essay outlines the choice spectrum and provides criteria and guidelines for the metric-selection process. It is suggested that the panel considers four critical dimensions of potential alternatives, namely means versus ends, objective versus subjective information, aggregate index versus multiple indicators, and monetary versus other units. In deciding about each dimension, serious attention needs to be given to the psychological-communicative appeal of the resulting options, so as to guarantee a fluent uptake of the selected beyond-GDP metric in society, media and politics. The combined environmental and inequality crises at national and global scales make this the right time to finally translate a respectable history of beyond-GDP thinking into practical action

    Harvesting and Conversation in a Predator-Prey System

    Get PDF
    Optimal harvesting of prey in a predator-prey ecosystem is studiedunder the condition that the existence of the predator has value. Predators (birds) and humans (fishers) compete for prey (shellfish). The behavior of the system is studied and conditions for optimal control are deduced. Various optimal harvesting rates are identified for particular ecosystem characteristics, harvesting costs, the discount rate value, and value functions for birds. These optimal harvest rates are constant harvesting, at levels possibly leading to the extinction of birds, or oscillating harvesting, giving rise to oscillating stocks of birds and shellfish. The approach path towards an optimal regime is shown qualitatively and consists of alternating between harvesting maximally and not harvesting at all

    Global environmental change, local land use impacts and socio-economic response strategies in coastal regions

    Get PDF
    This paper addresses the issue of possible land use strategies and responses in coastal zones as a consequence of global environmental change. It willfirst set out some key elements in global change that are of critical importance for the water and land management in such areas. Next, it will map outin more detail the various environmental and socio-economic repercussions of such megatrends. This will then be followed by a discussion of thenecessity to develop proper coastal zone management policy strategies in order to cope with uncertain challenges. In particular, the research needs will be addressed. The paper will then illustrate the potential of integrated coastal zone dynamic and spatial modelling and evaluation, on the basis of anempirical case study for a coastal region. Furthermore, a number of spatio-economic scenarios related to sea level issues in the Netherlands will bepresented. In this context also risk assessment is shortly discussed in relation to sea level rise

    A higher rebound effect under bounded rationality : interactions between car mobility and electricity generation

    Unidad de excelencia María de Maeztu MdM-2015-0552It is widely believed that with the right economic incentives, electrification of transport can significantly reduce CO₂ emissions by 2050. Estimates of future emissions from car transport tend, though, to ignore technological change in electricity generation and bounded rationality of consumers. In this article we address these two shortcomings by developing a novel approach that captures the dynamic interdependence between the car industry and electricity generation. We assess how incorporating realistic behaviors affects estimates of emissions from passengers cars in four models of vehicle adoption, namely with rational, myopic, habit-oriented and loss-aversive consumers. This is then combined with three behavioral models of travel distance, describing rational, habitual and loss-averse drivers. In the electricity sector, technological change occurs through installation of new power plants embodying different energy technologies. This allows us to study the impact of policies promoting renewable energy on the price of electricity, and indirectly on the rate of adoption of electric cars. The findings indicate that substituting renewable energy for fossil fuels in electricity generation by 2050 can triple the electricity price. This undermines the positive effect of subsidies on electric car adoption, with the specific effect depending on particular behaviors assumed to hold. In addition, we show that myopic and loss-averse consumers buy on average less fuel-efficient cars than rational agents. Habitual drivers tend to commute larger distances than rational ones, as they do not adjust their behavior optimally to changes in fuel prices and improvements in fuel efficiencies. These behavioral effects contribute to the rebound effect. Our findings indicate that vehicle choice and driving under rational behavior generate consistently the lowest estimates of life-cycle emissions. By ignoring more realistic behaviors consistent with bounded rationality, current studies underestimate emissions from passenger cars, in turn contributing to overly optimistic expectations about policy impacts

    Modeling Spatial Sustainability: Spatial Welfare Economics versus Ecological Footprint

    Get PDF
    A spatial welfare framework for the analysis of the spatial dimensions of sustainability is developed. It incorporates agglomeration effects, interregional trade, negative environmental externalities and various land use categories. The model is used to compare rankings of spatial configurations according to evaluations based on social welfare and ecological footprint indicators. Five spatial configurations are considered for this purpose. The exercise is operationalized with the help of a two-region model of the economy that is in line with the ‘new economic geography’. Various (counter) examples show that the footprint method is not consistent with an approach aimed at maximum social welfare.Agglomeration effects, Trade advantages, Negative externalities, Population density, Spatial configuration, Transport

    The Impact of Environmental Policy on Foreign Trade: Tobey revisited with a Bilateral Flow Model

    Get PDF
    Whereas theoretical analyses of trade and environment indicate thatrelatively strict environmental policies can have a strong impact on foreign trade, empirical studies present mixed results. This study presents new empirical results that tie together two previous empirical studies employing a multicountry econometric framework, notably Tobey (1990, 1993) and van Beers and van den Bergh (1997). Such a link is useful since most empirical studies on trade and environment use unique assumptions and models, thus making a comparison of findings very difficult if not impossible. Since Tobeys study has been particularly influential on writings in this area a statistical analysis has been performed using a data set that shares many characteristics with his study. The main improvement of the approach adopted here is the use of more disaggregate data. In addition, as the effect of environmental policy on international trade is likely to differ between sectors analyses are performed for a variety of sectors. The results provide partly support for Tobey, namely no significant effects for dirty trade. Results for total trade flows, however, show a positive effect of relatively strict environmental policy on exports. This suggests that either Tobey's policy indicator is inaccurate, or essential variables are missing in the regression model, or countries employed complementary measures such as export subsidies in combination with relatively strict environmental regulations. Sector specific regressions results allow for further comparison with Tobey and provide additional support for the previous conclusions
