As variáveis sócio-demográficas são um dos fatores que mais influenciam a escolha dos formatos de varejo do consumidor para a compra de alimentos. Ao analisar essas variáveis e a provável associação com a compra de alimentos, é possível desenhar um perfil dos consumidores que...

The Lower Tagus River Valley has been affected by severe earthquakes comprising distant events, as in 1755, and local earthquakes, as in 1344, 1531, and 1909. The 1909 earthquake was located NE of Lisbon, near Benavente, causing serious damage and many losses. Mw 6.0 has been assessed for this...

We decompose annual average years of schooling series for Portugal into different schooling levels series. By estimating a number of vector autoregressions, we provide measures of aggregate and disaggregate economic growth impacts of different education levels. Increasing education at all levels...

A multimove sampling scheme for the state parameters of non-Gaussian and nonlinear dynamic models for univariate time series is proposed. This procedure follows the Bayesian framework, within a Gibbs sampling algorithm with steps of the Metropolis–Hastings algorithm. This sampling scheme...

Typically, studies on regional wage differentials are based on ordinary least squares (OLS) estimates. Quantile regression is an alternative approach which allows...

Unlike previous studies, in this paper we estimate the contribution of covariates for the regional wage decomposition components along the wage distribution employing a method first described in 2009 by S Firpo, N Fortin, and T Lemieu (<i>Econometrica</i> <b>77</b> 953–973). We consider the case of...

This paper studies the time series effect of changes in liquidity on optimal portfolio allocations. Using a nonparametric approach, we are able to handle models that are analytically intractable. Specifically, we directly estimate optimal portfolio weights for a CRRA investor as functions of...

In this paper we use two alternative approaches to study the extent of gender wage discrimination in Portugal. Both methods involve the estimation of wage equations for males and females and the Blinder [1973] and Oaxaca [1973] decomposition. However, to take into account possible sample...

We decompose an annual average years of schooling series for Portugal into different schooling levels series. By estimating a number of vector autoregressions, we provide measures of aggregate and disaggregate economic growth impacts of different education levels. Increasing education at all...

Este artigo tem por objectivo analisar a mobilidade geográfica em Portugal tendo como domínio de referência a distância da deslocação. Tanto quanto é do nosso conhecimento, este é o primeiro trabalho que aborda esta questão em Portugal. A análise é efectuada com base num modelo logit...
