Our work looks for empirical evidence for the theoretical work proposed in the past. We use cross-country data from 1960 to 2002 to validate those principles. More precisely, our objective is to quantify the extension of life expectancy improvement that can be explained by the ever increasing...

We develop a general equilibrium endogenous growth model in which final goods can be produced either in the Non-Observed Economy (NOE) or in the Official Economy (OE). In particular, by solving transitional dynamics numerically towards the unique and stable steady state, we show that, by...

In the dominant literature, the technological-knowledge bias that drives wage inequality is determined by the market-size channel. We develop an endogenous growth model with two technologies in which: a specific quality of labour, low or high-skilled, is combined with a specific set of...

This paper studies a non-degenerate price distribution for the homogeneous good within a model of endogenous directed technical change. A probability density function is analytically derived and shown to be related to the technology and innovation parameters of the model.

The Perpetual Inventory Model (PIM) assumes that, in each period, an arbitrary constant fraction of technological-knowledge stock is lost. We give a theoretical background to the PIM by showing that the technological-knowledge accumulation follows a dynamic process with an endogenous...

The recent widening of intra-country wage inequality in favour of high-skilled labour has been attributed by some authors to Skill-Biased Technological Change (SBTC) and by others to International Trade (IT) liberalization. As few empirical studies have tried to assess both explanations across a...

The explanation of the recent increase in intra-country wage inequality in favour of high-skilled labour has been dominated by two explanations: skill-biased technological change (SBTC) and international trade (IT) liberalization. Since few empirical studies have tried to assess both...
