Is demand for polluting goods manageable? an econometric study of car ownership and use in Mexico
Full text linkCharging for social marginal costs is efficient regardless of price elasticities, but the importance of getting prices"right"is greater the more manageable, or elastic, the demand. In efficient pollution control programs, options to make cars cleaner are combined optimally with demand conservation. The roles played by"cleaner cars"as compared with"fewer trips"are determined by empirical parameters: cheap, clean technologies would imply a great role for cleaner cars, while high demand elasticities lead to a greater role for demand reduction. In seminal research, evisence was found to support the hypothesis that demand for commodities such as gasoline should have lower price elasticities and higher income elasticities in developing than in industrial countries. The authors estimate a model of gasoline demand and car ownership in Mexico, using a panel of annual observations by state. Key features they introduce are instrumental variables on different data and the treatment of (1) possible dynamics, (2) measurement errors in the data, and (3) unobserved characteristics in individual states. They use tests of serial correlation in the residuals to model the dynamics properly. The resulting model is one of almost immediate adjustment, with a short-term price elasticity for gasoline close to the long-term estimate of -0.8. The model displays elasticities that are lower (for income) and higher (for price) than those hypothesized, and are within the range of elasticities found in industrial countries. Byproducts of the model: The elasticity of car purchases with respect to gasoline prices is positive. Scrappage decisions are affected by income and by car and gasoline prices. And these elasticities are not significantly different in the richer states. For policy purposes, these findings do not support"elasticity pessimism"The use of car services is sensitive to pricing, which suggests that consumers, for some of their demand, have reasonably good alternatives to car services. Consideration of external costs - such as accidents, congestion, air pollution, and road damage - thus involve considerable demand conservation.Inequality,Transport and Environment,Energy and Environment,Economic Theory&Research,Environmental Economics&Policies
Demanda e resposta
No full textThe present article is about the binomial demands and responses under the perspective of the process as a bilateral tutelage where the author as well as the defendant require an initial demand which delimits the whole jurisdictional activity: The author expects the defendant's reluctancy to be declared and injustified. The defendant on the other hand claims his contraposition to the demander's intention is just. Therefore, the State will have intervene in order to fairly indicate which posture should prevail and by doing so pacify the dispute.O artigo trata do binômio demanda e resposta sob a perspectiva do processo como tutela bilateral, onde tanto o autor quanto o réu deduzem uma demanda inicial, que delimita toda a atividade jurisdicional. O autor objetiva que a resistência do réu seja declarada injustificada e cesse, por seu turno, o réu pretende a declaração de que é justa a sua contraposição a pretensão do demandante. De tal forma, o Estado virá intervir para, imparcialmente, indicar qual postura há de prevalecer, pacificando o conflito
Education and earnings inequality in Mexico
Full text linkEducation attainment levels increased dramatically for Mexico's labor force in the 1980s and early 1990s. In parallel, the country experienced a pronounced increase in earnings inequality from 1984-94, reflected in a higher dispersion of wages and an absolute decline in the real incomes of less educated, poorer Mexicans. This increased wage dispersion presents policymakers with a tradeoff between efficiency considerations (favoring increased spending on higher education) and equity considerations (favoring a more equal distribution of per student spending) in the allocation of fiscal resources to education. The author concludes that the best way to deal with this equity-efficiency tradeoff is to encourage greater private participation in higher education. His main findings are that: a) The accumulation of human capital during 1984-94, as proxied by education attainment, was accompanied by a more equal distribution of education attainment levels over that period and, thus, exerted an equalizing effect on the distribution of incomes. The increased income inequalityobserved over that period appears to be caused by an increased rate of skill-based technological change, whose transmission to Mexico and other developing countries may have been facilitated by the increased openness of their economies. b) The greater dispersion of wager observed in Mexico during the past decade raised the rates of return on investing in higher education, reversing the traditional pattern where primary education exhibits the highest rates of return. c) The social rates of return across levels of schooling were more uniform in 1994 than in 1984, suggesting a more efficient assignment of education spending. At the same time, the distribution of spending on education became more egalitarian, as per student spending in higher education declined markedly compared with per student spending at the primary level. This surprising coincidence in the pattern of spending on education was only possible because Mexico started out with a very distorted resource allocation in education that was both highly inequitable and inefficient. As Mexico's policymakers are on the way to correcting these distortions, the opportunities for avoiding the equity-efficiency tradeoff within Mexico's centralized education framework will become progressively exhausted. d) There is little reason to expect the pace of technological change, which appears mainly responsible for raising wage dispersion and the relative returns on higher education, to abate. Efficiency considerations dictate that Mexico should respond by devoting more resources to higher education. However, the federal budget, which traditionally has financed the lion's share of higher education costs in Mexico, is unable to accommodate additional spending on higher education, while spending cuts elsewhere in the education sector are bound to raise serious equity questions. Thus, to avoid falling behind in terms of human capital accumulation, greater private sector participation is necessary, at least, in terms of cost recovery from the main beneficiaries of higher education.Decentralization,Teaching and Learning,Environmental Economics&Policies,Public Health Promotion,Curriculum&Instruction,Teaching and Learning,Environmental Economics&Policies,Health Monitoring&Evaluation,Gender and Education,Curriculum&Instruction
Demanda efetiva e desenvolvimento regional
Full text linkThis paper aims at rescuing the relationship among effective demand, market development, innovation, productivity and regional development. In the author’s point of view, the contemporary regional literature usually overestimates the link between innovation and development, ignoring the fact that effective demand is the real basis on which the market system and the labor division is structured. Trying to prove this point of view the author formalizes the “Smith’s dilemma” and shows that the sole solution of this game that maximizes the benefits of all players is easily achieved after the development of a regional “export basis”.Neste trabalho buscamos resgatar a relação entre demanda efetiva, mercantilização, inovação, produtividade e desenvolvimento regional. Quer nos parecer que a literatura recente sobre o tema, a despeito de reconhecer os elos finais da corrente suprarreferida, usualmente subestima a centralidade – e, no limite, a anterioridade – da demanda efetiva na impulsão inicial dos processos de desenvolvimento. Para corroborar nosso ponto de vista, formalizamos, com ajuda da Teoria dos Jogos, o que denominamos “dilema de Smith” e procuramos demonstrar que a solução adequada do mesmo pressupõe a adoção de estratégias do tipo “base de exportação” teorizada por Douglass Nort

Modelos de predição de séries temporais aplicados à demanda de energia elétrica da Califórnia
Full text linkOrientador: Pr. Dr. Luiz Eduardo S. OliveiraMonografia (especialização) - Universidade Federal do Paraná, Setor de Ciências Exatas, Curso de Especialização em Data Science & Big Data.Inclui referênciasResumo: O trabalho mostra duas técnicas de predição de séries temporais, o tradicional ARIMA e a de deep learning chamada LSTM, aplicadas à demanda por energia elétrica na Califórnia. As bases de dados contêm a demanda residencial por energia elétrica, baixadas do site do departamento de energia dos Estados Unidos e tratada pelo autor. Foram separadas duas bases de dados para realizar as predições, demanda hora por hora e demanda média diária. O método ARIMA se mostrou mais eficiente para a predição de demanda por hora enquanto o modelo LSTM foi mais eficiente para a predição de demanda diária. O trabalho mostra também que o modelo de deep learning é mais eficiente para predições com bases de dados de maior tamanho do que o modelo tradicional ARIMA.Abstract: The paper shows two time series prediction techniques, the traditional ARIMA and the deep learning one called LSTM, applied to the electricity demand in California. The databases contain residential electricity demand, downloaded from the US Department of Energy website, and handled by the author. Two databases were separated to perform the predictions, hourly demand, and daily average demand. The ARIMA method proved to be more efficient for predicting hourly demand while the LSTM model was more efficient for predicting daily demand. The work also shows that the deep learning model is more efficient for predictions with larger databases than the traditional ARIMA model

Incisiones (cárcavas) en el nivel supraforestal de la Sierra de la Demanda (Sistema Ibérico): Morfología y significación
No full textIn this paper the author studies the incisions that appear above timberline in Sierra de la Demanda (Iberian System, Spain). These are isolatedly localized on the heads of ravines and on the slopes connecting with the drainage network. They reveal, together with other processes, the important erosion that these areas tolerate. The incisions can be consequence of the drainage network evolution and readjustement, reinforced by other local factors such as faults, a deep mantle of screes or deforestation.En este articulo se estudian un conjunto de incisiones que surgen en el nivel supraforestal de la Sierra de la Demanda (Sistema Ibérico). Estas se presentan en las cabeceras de los barrancos y vertientes deforma aislada, conectando con la red principal. Manifiestan, junto con otros procesos, el importante grado de denudación que soportan los sectores elevados de la Sierra. Las incisiones parecen ser consecuencia de la evolución y reajuste de la red fluvial: demandina, como consecuencia de la conjunción de una serie de factores (existencia de fallas, un manto de derrubios muy erosionable, deforestación)
