The capital structure of companies has given rise to many works of analysis of its determinants. The research has evaluated the relevance of the determinants of managers’ options when making a decision on the type of financing. The present study evaluates the effects on debt, of the...

This paper develops an empirical approach using econometric techniques for panel data which aims to contribute to the reduction/elimination of the deviation between the book and market value of firms. Based on 20 of the firms with the largest number of patents granted between 1996 and 2006, the...

Given a panel of oil producing countries, we show that a higher oil concentration is associated with an increase in economic growth through capital efficiency in: (i) countries with medium and low income per head from East Asia & Pacific and Latin America & the Caribbean, classified as followers...

This study re-evaluates the impact of natural resources on growth using panel data and a factor-efficiency accounting framework. The resource-curse thesis is dismissed as capital efficiency is improved by geographically-concentrated natural resources, which hinder institutional quality in recent...

In this study we re-evaluate the impact of natural resources on economic growth. The reassessment is based on a growth model where, using panel-data analysis, natural-resource variables (geographically diffused and concentrated) affect the efficiency gains of labour and capital in production. We...

Since Hsiao [1986]’s work, many surveys have appeared, providing the researcher with the necessary tools for fully enjoying the advantages of panel data in terms of both microeconometric and macroeconometric studies. This survey has this very aim and, in a sense, offers no novel contribution,...

This paper examines the relationship between Foreign Direct Investment (FDI) and international trade. Specifically, the relationship between the stocks of inward FDI and outward FDI, and Imports and Exports in the Portuguese economy. This paper also studies some technical problems associated...

Although the conventional R&D-patents relationship is a long stand and relatively undisputed issue within the innovation literature, the reverse causality, in particular, the potential for a negative impact of patents over R&D has only recently received wide attention boosting interesting...

The impact of foreign direct investment (FDI) on host country market concentration has been a controversial issue, both at the theoretical and the empirical levels. Most existing empirical studies point to a positive relationship, enhancing the negative effects of FDI on competition conditions,...

Human capital is identified as one of the main determinants of economic growth and plays an important role in the technological progress of countries. Nevertheless, existing studies have to some extent neglected the importance of human capital on growth via the interaction it can have with a...
