The Relationship between Knowledge Intensity and Market Concentration in European Industries: An inverted U-Shape

Abstract
This paper is motivated by the European Union strategy to secure competitiveness for Europe in the globalising world by focussing on technological supremacy (the Lisbon - agenda). Parallel to that, the EU Commission is trying to take a more economic approach to competition policy in general and anti-trust policy in particular. Our analysis tries to establish the relationship between increasing knowledge intensity and the resulting market concentration: if the European Union economy is gradually shifting to a pattern of sectoral specialisation that features a bias on knowledge intensive sectors, then this may well have some influence on market concentration and competition policy would have to adjust not to counterfeit the Lisbon-agenda. Following a review of the available theoretical and empirical literature on the relationship between knowledge intensity and market structure, we use a larger Eurostat database to test the shape of this relationship. Assuming a causality that runs from knowledge to concentration, we show that the relationship between knowledge intensity and market structures is in fact different for knowledge intensive industries and we establish a non-linear, inverted U-curve shape.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches

No. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.

Structural change, specialization patterns, and the productivity gap between Central and Eastern Europe and the European Union

Abstract
The transition countries of Central East Europe exhibit significantly lower productivity levels than that of the average of the 15 European Union countries. Since the outset of transition, however, this gap has clearly narrowed.
Next to technological and organisational factors it is sectoral structures which play an important role for the development and level of national productivities: in most transition economies, structural change clearly contributed positively to productivity growth. Poland is an exception here, no significant effect of structural change between sectors and industrial branches on the growth of the national productivity level could be found. The low intensity of structural adjustment in Poland in particular in the agricultural sector corresponds with a decisive role played by the sectoral pattern of specialisation within the European division of labour as determinant of the productivity gap. Hungary and to some degree also Slovenia, the country with the lowest productivity gap, exhibit similar results. Only in the cases of the Czech Republic and Slovakia remain negligible the explanatory powers of respective patterns of specialisation as productivity determinants.
