Households face earnings risk which is non-normal and varies by age and over the income distribution. We show that allowing for these rich features of earnings dynamics, in the context of a structurally estimated life-cycle portfolio choice model, helps to rationalize the limited participation...

Cet article propose une estimation de la production potentielle et un modèle d’écart de production au Liban en utilisant plusieurs méthodes statistiques comme la méthode de la tendance linéaire, le filtre d’Hodrick-Prescott et la méthode de la tendance segmentée. Dans la mesure où le...

We examine the effect of uncertainty arising from policy-shock volatility on yield-curve dynamics. In contrast to the assumption of many macro-finance models, policy-shock processes appear to be time varying and persistent. We allow for this heteroskedasticity by constructing a no-arbitrage...

The gravity model has become an efficient tool in the analysis of international economic relations due to its theoretical derivation and ability to explain these relationships. The contending issue now is the appropriate specification and estimation techniques. This paper presents a review of...

The structure of wages and wage determinants has always received attention in economic theories and policies. During the liberalized era, despite labour productivity, market based policies have gained importance in determining the wages. In the present study, the following issues are addressed:...

A dynamic panel data model is considered that contains possibly stochastic individual components and a common fractional stochastic time trend. We propose four different ways of coping with the individual effects so as to estimate the fractional parameter. Like models with autoregressive...
