Structural and technological change in the European periphery: The case of Portugal
Pessoa, Argentino - Faculdade de Economia, Universidade do Porto - 2013
In the past Portugal managed to grow at a significant rate, but the pace has getting slower and slower from decade to decade, until becoming practically stagnant in the first decade of the 21st century. This stumpy growth together with the current debt crisis has fed the rhetoric of structural...

A tale of two countries: a directed technical change approach
Leite, Duarte; Afonso, Óscar; Silva, Sandra - Faculdade de Economia, Universidade do Porto - 2014
It is widely recognized that scientific research has a dramatic impact on economies since it is crucial to foster technological knowledge. Today’s migratory movements and concentration of highly educated population and population with high scientific potential in developed countries play an...

Costly Investment, Complementarities, International Technological-Knowledge Diffusion and the Skill Premium
Afonso, Óscar; Neves, Pedro; Thompsom, Maria - Faculdade de Economia, Universidade do Porto - 2010
We examine the behavior of the skill premium in a two-country general equilibrium growth model assuming (i) technological-knowledge diffusion; (ii) internal costly investment in both physical capital and R&D; and (iii) complementarities between intermediate goods in production. We find that these...

Costly Investment, Complementarities and the Skill Premium
Afonso, Óscar; Thompson, Maria - Faculdade de Economia, Universidade do Porto - 2009
We propose a new framework to analyse the wage premium behaviour. Building on Acemoglu and Zilibotti (2001), we introduce physical capital and two assumptions: (i) internal costly investment in both capital and R&D; (ii) complementarities between capital goods in production. We find that, for...

Numerical computation for initial value problems in economics
Afonso, Óscar; Vasconcelos, Paulo B. - Faculdade de Economia, Universidade do Porto - 2006
We summarise Runge-Kutta type methods for the solution of ordinary differential equations in models of economic dynamics. In this work we are going to present explicit Runge-Kutta type methods, a family of methods to solve numerically systems of ordinary differential equations, without the need...

Explaining Differences in the Productivity of Capital Across Countries in the Context of ‘New’ Growth Theory
Nell, Kevin S.; Thirlwall, A.P. - Faculdade de Economia, Universidade do Porto - 2014
The purpose of this paper is to explain differences in the productivity of capital across countries taking 84 rich and poor countries over the period 1980-2011, and to test the orthodox neoclassical assumption of diminishing returns to capital. The marginal product of capital is measured as the...

Price-Channel Effects of North-South Trade on the Direction of Technological Knowledge and Wage Inequality
Afonso, Óscar; Aguiar, Álvaro - Faculdade de Economia, Universidade do Porto - 2005
This paper develops a general equilibrium endogenous growth model that emphasizes the mechanisms, other than market size, through which trade-induced North-South technological knowledge diffusion influences the direction of technological progress and, thus, the path of intra and inter-country...

Effects of Learning-by-doing, technology-adoption costs and wage inequality
Leite, Rui; Afonso, Óscar - Faculdade de Economia, Universidade do Porto - 2008
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...
