TL;DR: In this article, the authors examine sensitivity of the estimated relationship between innovation and firm performance using a knowledge production function approach and carry out comparisons in a number of ways, such as using the same data source, an identical model but different data sources, different classifications of firms performance, different classes of innovation and the two main different subpopulations of the business sector.

TL;DR: In this paper, an empirical analysis of knowledge capital and performance heterogeneity at the firm level is presented, which applies new econometric methods to extensive data on innovation and innovative activities.

TL;DR: Applying a knowledge production function that gives the relationship between innovation input, innovation output and productivity, this paper finds to a very large extent a common cross-country story for knowledge intensive manufacturing firms.

TL;DR: In this paper, the authors present an econometric analysis of the impact of collaboration with universities on the innovative output of firms and illustrate the differences that emerge from robustness checks, based on different matching estimators and samples.

TL;DR: In this article, the authors present a comprehensive description and analysis of the international trading activities of firms based on novel and detailed Swedish data and provide robust evidence of selection operating from market to market which is consistent with that low productive firms are confined to markets with low productivity thresholds.
