Abstract [en]

This paper is an empirical analysis of knowledge capital and performance heterogeneity at the firm level. We apply new econometric methods to extensive data on innovation and innovative activities in Swedish manufacturing. A number of interesting results emerge. First, the results show that knowledge capital, defined as the ratio of innovation sales to total sales, is found to be a significant factor contributing to performance heterogeneity among firms. This relationship holds even when we control for human capital, type of output, firm size. and the entry. merger., partial closure or exit of firms. Second. knowledge capital rises with innovation input. the firm's internal knowledge for innovation, and co-operation on innovation with domestic universities. Third, when controlling for differences in innovation investments and human capital, knowledge-intensive firms are not more innovative than labor-intensive or capital-intensive firms. Fourth, organizational rigidities in innovation projects and a lack of appropriate investment sources for innovative activities are found to have a negative impact on productivity. Finally, we find a positive association between an outspoken aggressive innovation strategy, customers and a firm's internal resources for innovation and the size of innovation investment.

Abstract [en]

This doctoral thesis consists of five self-contained essays.Common themes that unify the essays are the conditions for innovative engagements and the effort to endogenize innovations into the explanation of profitability, productivity and growthin manufacturing and service production. The purpose is to explore the importance of innovation in explaining heterogeneity in the performance of firms. The traditional analysis of the relationship between research and developmentand productivity is extended and developed by using, on the onehand, firm-level data not previously available and, on theother, a modern state-of-the-art econometric framework.

Essay I. Methods and results are reviewed and stylized facts presented regarding the return on innovation. The limitations of the data and methods used in mainstream literature are discussed. A set of firm-level observations recently made available and a multiple knowledge production function analysis have been used to clarify the role of innovation in explaining performance heterogeneity among manufacturing firms inSweden.

Essay II. The relationships between innovation and productivity among manufacturing firms in Finland, Norway and Sweden are studied. The main purpose is to investigate the contributions of firm-level innovation in creating the large observed differences in aggregated productivity growth between Norway on the one hand and Finland and Sweden on the other.

Essay III. The focus of this essay is threefold. One, since innovation has been found to be a major contributor to productivity growth in manufacturing, we seek to find whether there is any evidence for the notion that service industrie shave a lower propensity to be innovative or that they are less efficient in deriving benefits from innovations. Second, we consider what real productivity growth does, and what the measurement methods do to produce the reported weak growthrates in services. Third, given that intermediate services have been found to be one of the fastest growing input factors inmanufacturing, largely reflecting the replacement of internally provided activities by externally produced outputs, we examine what the impact of outsourcing is on productivity growth in manufacturing. The essay brings a comparative perspective to these issues by analyzing the firm-level data on innovativeactivities and economic performance in knowledge-intensive manufacturing and service firms in Sweden.

Essay IV.This essay investigates the sensitivity of estimated relationships between innovation and firm performance. The essay compares the sensitivity of results with regards to different types of models, estimation methods, measures of firm performance, classification of firms, type of innovations and data sources. The analyses are performed on both the level and growth rate of firm performance, and theinfluence of outliers is explored.

Essay V. The role of capital structure and external financing in innovation and production is studied. Results from different model specifications are explored. A preferred dynamic model with flexible adjustment is used for an inter-country and an intra-country comparison of the determinants of the optimal mix between debt and equity as wellas the rate of change towards an optimal capital structure.
