Oil price shocks and the Portuguese economy since the 1970s

This paper assesses empirically the effect of oil price shocks on Portuguese aggregate economic activity, industrial production and price level. We take the usual multivariate VAR methodology to investigate the magnitude and stability of this relationship. In doing so, we follow the approach presented in the recent literature and adopt different oil price specifications. We conclude that, as for most industrialized countries, the nature of this relationship changed in the mid-1980s. Furthermore, we show that the main Portuguese macroeconomic variables have become progressively less responsive to oil shocks and the adjustment towards equilibrium has become increasingly faster.

The transformation of work? A quantitative evaluation of changes in work in Portugal

This report is made for the Work Package 15 of WORKS project and tries to develop more information on the Portuguese situation in the work structures changes in the recent years. It starts with an analysis of socio- economical indicators (Macro economical indicators, Employment indicators, Consumption, Technology at the workplace, Productivity), and then approaches the situation in terms of work flexibility in its dimensions of time use and New forms of work organisation. It traces employment in business functions with a sectoral and occupational approach, and analyses the occupational change in South Europe with particular relevance to Portugal (skill utilisation and job satisfaction, occupational and industrial mobility, quantitative evaluation of the shape of employment in Europe. Finaly are analysed the globalisation indicators.

Return Migration, Self-Selection and Entrepreneurship in Mozambique

Does return migration affect entrepreneurship? This question has important implications for the debate on the economic development effects of migration for origin countries. The existing literature has, however, not addressed how the estimation of the impact of return migration on entrepreneurship is affected by double unobservable migrant self-selection, both at the initial outward migration and at the final inward return migration stages. This paper uses a representative household survey conducted in Mozambique in order to address this research question. We exploit variation provided by displacement caused by civil war in Mozambique, as well as social unrest and other shocks in migrant destination countries. The results lend support to negative unobservable self-selection at both and each of the initial and return stages of migration, which results in an under-estimation of the effects of return migration on entrepreneurial outcomes when using a ‘naïve’ estimator not controlling for self-selection. Indeed, ‘naïve’ estimates point to a 13 pp increase in the probability of owning a business when there is a return migrant in the household relative to non-migrants only, whereas excluding the double effect of unobservable self-selection, this effect becomes significantly larger - between 24 pp and 29 pp, depending on the method of estimation and source of variation used.

Perfil lipídico e fatores biológicos e ambientais : o papel da atividade física

RESUMO - Introdução: A inatividade física é um dos determinantes major das doenças crónicas não transmissíveis sendo a quarta maior causa de mortalidade no mundo, nomeadamente para as doenças vasculares. A prática regular de atividade física produz adaptações vasculares responsáveis por efeitos benéficos na prevenção e tratamento dos diferentes fatores de risco vascular, nomeadamente através do seu efeito no metabolismo das lipoproteínas. Objetivos: Analisar a interferência da atividade física no perfil lipídico de uma população residente em Portugal. Métodos: Estudo observacional descritivo transversal exploratório com 1027 indivíduos (idade: 18 aos 80 anos, 49% mulheres). Os dados foram analisados em SPSS (versão 20), tendo-se utilizado métodos de estatística descritiva e de análise bivariável entre os factores de risco vascular e as variáveis do perfil lipídico e ainda uma análise multivariável de regressão logística binária para medir a razão de riscos pelo odds ratio. O nível de significância foi estabelecido em 5%. Resultados: Na análise da relação entre atividade física e os biomarcadores do perfil lipídico verificou-se que existem benefícios no que diz respeito ao aumento dos níveis de HDL e de apoA1 e na diminuição dos níveis de TG com a prática regular de atividade física. Conclusões: A atividade física apresenta um papel importante na regulação do perfil lipídico evidenciando a necessidade de implementar estratégias multissectoriais de prevenção dos fatores de risco vascular, nomeadamente na área dos estilos de vida saudáveis que são fundamentais para a prevenção destas condições de saúde e para gerar ganhos em saúde.
