To investigate whether there is a similar relationship between R&D intensity and growth in high-tech and non-high-tech small and medium-sized enterprises (SMEs), we examine two samples of SMEs in manufacturing industries, applying the two-step estimation method. Our findings are that R&D...

<title>Abstract</title> Using two step method, namely probit regressions and dynamic estimators, and on the basis of two sub-samples of Portuguese SMEs: 1) 495 young SMEs; and 2) 1350 old SMEs, this study seeks to verify if age is a important factor of the relationships between determinants and profitability....

This paper analyses the relationship between growth opportunities and debt of quoted Portuguese companies using various panel estimators. The results show a cubic relationship between growth opportunities and debt. When companies' growth opportunities are low and high, the relationship between...

This article uses quantile regressions to study the relationship between the growth of Portuguese small and medium enterprises (SMEs) and its determinants. To control a sample selection bias, we use a two-step estimation. In the first stage, we verified that past growth, size, age, R&D...
