While the empirical evidence tends to support some predictions of the life-cycle theory, a number of puzzles remain: an ageing-consumption, an ageing-saving, a saving-capitalisation and a saving-longevity puzzles have been put forward in the literature. This paper analyses the links between...

This paper analyses the impact of welfare systems and longevity on savings. It develops a life-cycle model embodying social transfers (health care and pension expenditures) and changes in longevity to determine the level of household savings. We simulated an aggregate saving equation and derived...

This paper examines the channels through which ageing will shape the main economic factors that in turn affect potential growth; identifies current policy settings that may in fact amplify the adverse impact of demographic trends; and sets out policy reforms that will work to temper the effects...

The combination of demographic factors and an increase in education has caused a significant rise of university graduates’ unemployment in the MENA region. The article provides a prospective cost- effectiveness analysis of the impact of alternative labor market policies using a dynamic general...

We show, in contrast with Stiglitz, that an inegalitarian long run equi- librium can emerge in a Solow growth model framework, with linear consumption function. We then interpret this result in line with marxian economics. We extend the results by incorporating some features of the...

The aim of this paper is to show that inequalities of wealth can be necessary conditions to explain the apparition and rise of a capitalistic system. We try to highlight Marx's insights on primitive accumulation. Our dynamic framework is consistent with Roemer's idea of endogenous class...

We reinvestigate the issue of excess comovements of commodity prices initially raised in Pindyck and Rotemberg (1990). While Pindyck and Rotemberg and following contributions consider this issue using an arbitrary set of control variables, we develop our analysis using recent development in...

Econometrics has strongly evolved in recent years on both the methodological level as well as in terms of applications. This article presents the different econometric methods (time series econometrics, information panels, models of duration,...) and their applications for the enterprise: demand...

As both speculative and hedging financial flows into commodity futures are expected to link commodity price formation more strongly to equity indices, we investigate whether these processes also create increased correlation amongst the commodities themselves. Considering U.S. oil and gas...
