This paper addresses electricity transmission planning under the new industry and institutional structure of the Mexican electricity market, which has engaged in a deep reform process after decades of a state-owned-vertically-integrated-non-competitive-closed industry. Under this new structure, characterized by a nodal pricing system and an independent system operator (ISO), we analyze welfare-optimal network expansion with two modeling strategies. In a first model, we propose the use of an incentive price-cap mechanism to promote the expansion of Mexican networks. In a second model, we study centrally-planned grid expansion in Mexico by an ISO within a power-flow model. We carry out comparisons of these models which provide us with hints to evaluate the actual transmission planning process proposed by Mexican authorities (PRODESEN). We obtain that the PRODESEN plan appears to be a convergent welfare-optimal planning process. © 2017 Elsevier Ltd

The distribution of plants is associated with their different patterns of response to their environment. Mediterranean plants have evolved a number of morphological and physiological adaptations that determine their ability to survive and grow, being an effective water uptake and use important factors for drought resistance. In this article, we evaluated interspecific differences in morphology, biomass allocation, and architectural traits and their relationship with water use strategies in seedlings of seven co-occurring Mediterranean species (Anthyllis cytisoides L., Genista scorpius L. DC., Myrtus communis L., Pistacia lentiscus L., Rosmarinus officinalis L., Spartium junceum L. and Ulex parviflorus Pourr.). The results showed that morphological root features vary among species and they are significantly correlated with root hydraulic conductance and leaf gas exchange variables. Species with high specific root length (SRL) showed a low hydraulic conductance per root length (KRRL) but high specific hydraulic conductance (KAs). M. communis and P. lentiscus showed the most contrasting water use patterns with respect to the other species studied. The results are not affected when considering phylogenetic relatedness. Thus, the variability observed in root hydraulic properties and leaf gas exchange suggests important mechanisms for understanding species coexistence in water-limited ecosystems. © Springer Science+Business Media B.V. 2009.

To date, the distributive implications of incentive regulation on electricity transmission networks have not been explicitly studied in the literature. More specifically, the parameters that a regulator might use to achieve distributive efficiency under price-cap regulation have not yet been identified. To discern these parameters is the motivation for the research presented in this paper. We study how different weight parameters affect the distributive characteristics of optimal price-cap incentive regulation for electricity transmission. We find that a regulator''s use of ideal (Laspeyres) weights tends to be more beneficial for the Transco (consumers) than for consumers (the Transco). Highlights: •Distributive implications of incentive regulation on transmission networks have not been studied in the literature.•The parameters that a regulator might use to achieve distributive efficiency have so far not been explicitly analyzed.•Analyze how different weights affect the distributive characteristics of price-cap regulation in electricity transmission.•Results: ideal (Laspeyres) weights tend to be more beneficial for the Transco (consumers) than for consumers (the Transco). © 2014 Elsevier Ltd.

We analyze regulatory regimes for electricity transmission investment in the context of transformation of the power system towards renewable energy. We study three distinctive developments of the generation mix with different implications on network congestion, which may be either of temporary or permanent nature. We address the relative performance of a combined merchant-regulatory price-cap mechanism, a cost-based rule, and a non-regulated approach in these three dynamic generation settings. We find that incentive regulation with Laspeyres weights may lead to overinvestment (stranded investment) as compared to the welfare optimum benchmark. Using Paasche weights leads to acceptable results only in a case of permanent exogenous congestion increase; in contrast, if (quasi) ideal weights are used, it is possible to restore the beneficial properties that incentive regulatory mechanisms are known for in static settings. This analysis motivates further research aimed to characterize optimal regulation for transmission expansion under a transforming renewable-based energy system. © 2013 IEEE.

In Mediterranean ecosystems, fire is a strong selective agent among plants, and the different post-fire regeneration strategies (e. g. resprouting and non-resprouting) have implications for other plant traits. Because young plants of non-resprouters need to grow quickly and mature well before the next fire, we predict that they should possess leaf traits related to increased efficiency in growth and resource acquisition compared with resprouter species. To test this hypothesis, we measured specific leaf area, leaf nitrogen and carbon concentrations and leaf physiological traits, including gas exchange parameters and chlorophyll fluorescence, in 19 Mediterranean species cultivated in a common garden. Both cross-species and phylogenetically informed analyses suggest that non-resprouters have better physiological performance at the leaf level (i. e. higher photosynthetic capacity) than resprouters. All these results suggest that non-resprouter species are able to take greater advantage for vegetative growth and carbon fixation than resprouters during periods when water is readily available. The contrasted physiological differences between resprouters and non-resprouters reinforce the idea that these two syndromes are functionally different (i. e. they are functional types). © 2011 Springer Science+Business Media B.V.

In this paper, a new Multi-Objective Evolutionary Algorithm (MOEA) named RankMOEA is proposed. Innovative niching and ranking-mutation procedures which avoid the need of parameters definition are involved; such procedures outperform traditional diversity-preservation mechanisms under spread-hardness situations. RankMOEA performance is compared with those of other state of the art MOEAs: MOGA, NSGA-II and SPEA2, showing remarkable improvements. RankMOEA is also applied to approximate the Pareto Front of a Dynamic Principal-Agent model with Discrete Actions posed in a Multi-Objective Optimization framework allowing to consider more powerful assumptions than those used in the traditional single-objective optimization approach. Within this new framework a set of feasible contracts is described, while others similar studies only focus on one single contract. The results achieved with RankMOEA show better spread and minor error than those obtained by already mentioned MOEAs, allowing to perform better economic analysis in the contracts trade-off surface.

Wildfires are an integral part of Mediterranean ecosystems; humans impact on landscapes imply changes in fuel amount and continuity, and thus in fire regime. We tested the hypothesis that fire regime changed in western Mediterranean Basin during the last century using time series techniques. We first compiled a 130-year fire history for the Valencia province (Spain, Eastern Iberian Peninsula, Western Mediterranean Basin) from contemporary statistics plus old forest administration dossiers and newspapers. We also compiled census on rural population and climatic data for the same period in order to evaluate the role of climate and human-driven fuel changes on the fire regime change. The result suggested that there was a major fire regime shift around the early 1970s in such a way that fires increased in annual frequency (doubled) and area burned (by about an order of magnitude). The main driver of this shift was the increase in fuel amount and continuity due to rural depopulation (vegetation and fuel build-up after farm abandonment) suggesting that fires were fuel-limited during the pre-1970s period. Climatic conditions were poorly related to pre-1970s fires and strongly related to post-1970s fires, suggesting that fire are currently less fuel limited and more drought-driven than before the 1970s. Thus, the fire regime shift implies also a shift in the main driver for fire activity, and this has consequences in the global change agenda. © 2011 Springer Science+Business Media B.V.

This article outlines the economics of non communicable chronic diseases (NCDs), necessary for designing evidence-based health policies to reduce the prevalence of NCDs. The main risk factors of NCDs are manmade: abuse of alcohol, tobacco, junk food, and lack of exercise. Hence we define an economic category of analysis, unwholesome goods. The analysis tackles the two dimensions of NCDs: individual and collective. The first one linked to how much NCDs are a result of consumer's choice and the second one, the recognition that NCDs are result of a complex interrelated environment at the society level, evidencing the need for a multisectoral approach. An economic analysis includes the study of 1) NCD in the context of intergenerational life cycle dynamics; 2) demand, supply, externalities, and political economy of NCD factors; 3) the incidence of lifestyle risks according to socioeconomic status, and changes under the impact of economic growth and the demographic transition. Where do the different countries lie on the development pathway? How much of the burden lies on the individual and on the collective dimensions of NCDs? What are the most effective policies for immediate application tackling both, the individual and collective dimensions? To what extent are households affected by financial catastrophe and impoverishment due to NCDs? What are the essential requirements for the health systems to respond with efficiency and efficacy to the NCDs phenomenon? Policy and research initiatives include health sector capability for NCDs, prevention of NCD factors, promotion of multisectoral approaches, and a comprehensive data initiative. Conclusions point to the need to simultaneously implement health policy and construct the necessary evidence bases. A comprehensive data initiative is proposed as needed in addition to expanding data availability in tandem with policy implementation. Finally an initiative is proposed to formulate sufficiently effective multisectoral policies and to establish the necessary links between the health sector and other sectors involved.
