Procura final de energia em Portugal: Existe evidência sobre a presença de memó...
Belbute, José ManuelA persistente escalada do preço dos combustíveis fósseis à qual está associada uma enorme volatilidade de curto prazo, assim como as crescentes preocupações com as emissões de gases com efeitos sobre as alterações climáticas, alimentou nos últimos anos a discussão e as preocupações de política, do seu desenho e eficácia, sobre as possibilidades de substituição das fontes energéticas. O presente artigo pretende...
Final energy demand in Portugal: How persistent it is and why it matters for en...
Pereira, Alfredo Marvão; Belbute, José ManuelThe objective of this paper is to analyze the degree of persistence of final energy demand in Portugal. Our results suggest the presence of a strong level of persistence for aggregate final energy demand. Final demand for gas is the most persistent component of energy demand, while the final demand for coal is the least persistent. In turn, final demand for petroleum and biomass tend to have levels of persisten...
Is the Euro-Area Core Price Index Really More Persistent than the Food and Ener...
Belbute, José ManuelThe purpose of this paper is to measure the degree of persistence of the overall, core, food and energy Harmonized Indexes of Consumer Prices for the European Monetary Zone (HICP-EAs) and to identify its implications for decision-making in the private sector and in public policy. Using a non-parametric approach, our results demonstrate the presence of a statistically significant level of persistence in four HIC...
Qualidade de Vida: Uma análise à escala local
Belbute, José Manuel Madeira; Marques, João; Carvalho, Jorge; Castro, Eduardo Anselmo; Pinto, Maria Luis; Gomes, PedroO tema deste artigo enquadra-se no âmbito do projecto “Custos e Benefícios, à escala local, de uma Ocupação Dispersa”. Esta investigação assenta a sua problemática na dispersão e procura chegar a conclusões e recomendações sobre o fenómeno do alastramento da dispersão; e sobre cenários desejáveis de evolução da ocupação dispersa existente, no que respeita à infra-estrutura e/ou à mobilidade e/ou à carga constru...
On the Relation Between the Endogenous Growth Rate of the Economy and the Dynam...
Belbute, José Manuel Madeira; Brito, PauloIn this paper we study a simple endogenous growth model in which the two engines of growth are the exogenous technical progress in dematerialization and the accumulation of a renewable natural resource. The model is also labeled as been "endogenous" as the rate of growth of natural capital is endogenously determined and should lie between zero and the rate of technical progress. In this context, it is possible ...
On Intertemporal Dependent Preferences with regard Environmental Goods and Serv...
Belbute, José Manuel Madeira; Brito, PauloThis note extends the standard theory of intertemporal consumer preferences with regard environmental goods and services. It proposes an intertemporal dependent preferences framework that generates a “persistence effect” consistent with consumer’s environmental friendly behaviours. Given the present civilizational and cultural pattern of preferences, consumers need to endure a learning-by-consuming process to f...
Literacia Económica entre alunos Universitários
Belbute, José Manuel Madeira; Sousa, Miguel Rocha deIt is widely recognized the important role played by human capital, knowledge and innovation for the establishment of the basic conditions for permanent economic growth. On particular aspect of this general issue interests us in particular; the level of economic literacy among young students who arrive at the university to get a degree not only in economic sciences (Economics, Management, etc) but also in other...
Constraints on Dematerialisation and Allocation of Natural Capital along a Sust...
Belbute, José Manuel Madeira; Rodrigues, João; Domingos, Tiago; Conceição, PedroThis paper extends the neoclassical growth model with natural capital by introducing two new concepts: allocation of natural capital and materialization. We consider that anthropogenic environmental impact is correlated with the throughput of the economy (materialisation). Materialisation is the material throughput per unit of economic activity. We capture the effect of the reduction of this throughput demateri...
Estabilidade Local em Problemas de Controle Óptimo com duas variáveis de Estado...
Belbute, José Manuel MadeiraO presente trabalho procura demonstrar que as condições exigidas por Dockner no teorema 3, mesmo para o caso da sociedade evidenciar impaciência face ao futuro (caso em que r > 0) podem fazer surgir não só os 4 valores próprios apenas com parte real a que o teorema se refere, como também dois pares de complexos conjugados sendo que dois deles têm parte real positiva e dois parte real negativa. Com isso, as traj...
