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...

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...

We propose a model where both R&D and ICT investment feed into a system of three innovation output equations (product, process and organizational innovation), which ultimately feeds into a productivity equation. We find that ICT investment and usage are important drivers of innovation in both...

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated...

There is growing evidence that firms increasingly adopt open innovation practices. In this paper we investigate the impact of two such external knowledge acquisition strategies, buy and cooperate, on firm's product innovation performance. Taking a direct (productivity) approach, we test for...

This paper examines the impact of the Dutch R&D tax incentives program, known as WBSO, on the wages of R&D workers. In our model these wages are partly determined by the governments WBSO tax disbursements. We construct detailed firm- and time specific R&D tax credit rates as a function of the...

This paper presents an econometric analysis of the characteristics of firm’s cooperating with universities using Community Innovation Survey (CIS) data for 14 European countries. Our model incorporates three groups of variables which could be related to the probability to cooperate with...

This paper examines the impact of the Dutch R&D tax incentives program, known as WBSO, on the wages of R&D workers. In our model these wages are partly determined by the governments WBSO tax disbursements. We construct detailed firm- and time specific R&D tax credit rates as a function of the...

Using direct information on financial constraints from questionnaires, rather than the commonly used balance sheet information, this paper presents evidence that, controlling for traditional factors as size, market share, cooperative arrangement, and expected profitability, financial constraints...

Research and development is a crucial activity in the innovation process. Not every firm is in a position to overcome constraints to R&D, such as costs. Those that perform R&D must choose between forming a partnership with other firms, governmental organisations, universities or doing it...
