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...

We build a general equilibrium model with renewable (non-polluting) and non-renewable (polluting) resources to analyze the interaction and compatibility between economic growth and a cleaner environment. The study is in two phases: (i) resource extraction/production costs are constant; (ii)...

Using a longitudinal database (1996--2003) at the plant level, this article analyses the causal nexus between international trade engagement and productivity in Portugal. By applying the propensity score matching and a differences-in-differences estimator, the learning-by-exporting hypothesis is...

Using panel estimation, this paper shows that higher oil abundance does not hinder crude producers' growth. This sample controls for specificities of oil economies, but the usual cross-section `curse' result is found—it disappears allowing for unobserved effects. The chosen model controls for...

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 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...

This paper builds an endogenous growth model of directed technical change with vertical and horizontal R&D and scale effects at the industry level to study an analytical mechanism that is consistent with the observed cross-country pattern in the skill structure, the technology structure and...

Abstract We propose an endogenous growth model with elements of new political economy in order to study the effects of political institutions and political rivalry on human capital accumulation and income inequality. Relating to the increasing literature on the relationship between income...
