It is clear that the successful management of water resources must take into account the influence of policies affecting the irrigated agriculture sector. Among these, the importance of the Common Agricultural Policy (CAP) and of the Water Framework Directive (WFD) is well recognised. In...

Most trade between the European Union (EU) and the Central and Eastern European Countries (CEEC) is inter-industrial in nature, based on comparative advantages. However, recent studies have uncovered structural changes in the nature of trade, the most unexpected being the rapid increase in...

This note shows in what circumstances output persistence may invert the pattern of the electoral cycle when inflation expectations are of the adaptive or rational type and the government preferences are quadratic over output and inflation

A análise dos resultados eleitorais em Portugal, quer ao nível das eleições legislativas quer das autárquicas, reconhece, de um modo geral, a existência de zonas geográficas onde a influência dos diversos partidos, sobretudo de alguns dos principais, parece ser mais evidente. Sendo certo...

As relações que existem entre alguns aspectos económicos, nomeadamente o crescimento, e alguns aspectos políticos, nomeadamente o nível de democracia, foram alvo de algum interesse teórico e também empírico (Alesina e Perotti, 1994; Alesina e Rodrik, 1994; Alesina et al., 1996; Barro, 1996). Neste...

It is rather evident that there is much more (statistical) information about objective aggregates, such as inflation, output or unemployment than that concerning subjective aggregates, such as well-being, satisfaction, confidence or even expectations. Due to its characteristics, fuzzy logic can...

This paper proposes novel methods for the construction of tests for models specified by unconditional moment restrictions. It exploits the classical-like nature of generalized empirical likelihood (GEL) to define Pearson-type statistics for over-identifying moment conditions and parametric...

O 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...

This note presents some of the consequences due to the possibility of having early elections. First of all, elections, whether exogenously or endogenously determined, are relevant to challenge the well known neutrality principle of economic policies under rational expectations. Furthermore, in...

Dynamic panel data (DPD) models are usually estimated by the generalized method of moments. However, it is well documented in the DPD literature that this estimator suffers from considerable finite sample bias, especially when the time series is highly persistent. Application of the...
