Using firm-level data from five developing countries--Brazil, Ecuador, South Africa, Tanzania, and Bangladesh--and three industries--food processing, textiles, and the garments and leather products--this article examines the importance of various sources of knowledge for explaining productivity...

Using Dutch data we empirically investigate how financing and innovation vary across firm characteristics. We find that when firms face financial constraints, debt financing and innovation choices are not independent of firm characteristics, and R&D slows down. In the absence of financial...

The purpose of this guideline is to provide ideas and technical advice on how to measure the effectiveness of Science, Technology and Innovation Programs (STIP). The paper addresses the specific challenges of evaluating STIP, from the assessment of the intervention logic to the choice of the...

In order to catch up with the current technological frontier, firms, especially in developing countries, try to acquire technological advancement through internal R&D efforts, as well as through external technology-sourcing activities. This study tests whether these two sources of technology...

This paper proposes a method to implement maximum likelihood estimation of the dynamic panel data type 2 and 3 tobit models. The likelihood function involves a two-dimensional indefinite integral evaluated using "two-step" Gauss-Hermite quadrature. A Monte Carlo study shows that the quadrature...

Almost all empirical research that has attempted to assess the validity of the Porter hypothesis has started from reduced-form models, e.g. by using single-equation models for estimating the contribution of environmental regulation (ER) to productivity. This paper addresses the Porter Hypothesis...

In this paper we evaluate the effectiveness of R&D tax incentives in Quebec, using manufacturing firm data from 1997 to 2003 originating from R&D surveys, annual surveys of manufactures and administrative data. The estimated price elasticity of R&D is -0.10 in the short run and -0.14 in the long...

This paper looks at the effectiveness of R&D grants for Canadian plants that already benefit from R&D tax credits. Using a non-parametric matching estimator, we find that firms that benefited from both policy measures introduced more new products than their counterparts that only benefited from...
