This contribution concerns models and theories of structural economic dynamics. The theories and models analyzed in the paper follow two different approaches, circular and vertical, in the analysis of structural dynamics. The content of this contribution is essentially methodological. This work...

Herbert Simon (1962) has treated the notion of complexity arguing that hierarchy is clearly an essential feature of complex systems. Yet, Simon states that the systems are not organized in a hierarchy in a simple way, because if they were, would be fully decomposed, while they are "nearly...

Structural analysis is the main topic of this paper and structural change is a dominant theme of the present work. The analysis of structural models and of theories of structural changes carried out in this paper has a double meaning. On the one hand, it allows to pick up several essential...

The study of structural changes is the theme of this work, where structural changes are correlated primarily with changes in the structure of production, which are caused by the evolution of technical progress and organizational changes in production. The analysis of models and theories of...

Structural change indicates essentially a qualitative transformation and evolution of the economic systems, usually marked by technological progress and organizational changes. Technological factors, knowledge, institutions are all elements that contribute to the process of structural change....

In this paper I will examine the growth models of Romer (1986) and Lucas (1988) which constitute an important first core to the endogenous growth theory, in order to understand the characteristics, to highlight the relationship between knowledge and economic growth and / or emphasize the...

Many claim that fluctuations in US private savings help to create and to sustain global imbalances because of their influence on the current account deficit. To test this claim, this paper investigates the determinants of aggregate household savings using a panel of 18 developed countries for...

This article investigates how wealth and capital gains affected household consumption in the USA in the period 1989-2004. The empirical evidence brought so far by a large literature that investigates the role of wealth shocks on consumption is mixed, due to the low quality of the data more...

This article investigates how wealth affected household consumption in the USA in the period 1989-2007. Previous empirical results are mixed, mostly because of the low quality of the data more readily available. We combine information from the Consumer Expenditure Survey and the Survey of...

How does household wealth influence consumption? The empirical evidence brought so far by the literature is unclear, mostly because of the low quality of the data more readily available: aggregate data, cross sections and panel datasets lacking important variables all present major shortcomings...
