A Panel Study of Firm Growth among SMEs in Networks

An underlying assumption in SME literature, as well as among policymakers, is that networks are good per se especially for SMEs. Through accessing and utilising external resources in the network, the SME can overcome some of the assumed disadvantages of limited size. Thus networking is assumed to enhance small firm performance and thereby small firm growth. This article investigates this assumption. Analysis of panel data ascertains that a substantial number of SMEs are actively networking and that the level of networking has been maintained over a five-year period. In spite of this there is no evidence of associated short-term benefits such as growth in employment or growth in total sales resulting from the networking activities. The analyses suggest, however, that networking is associated with high growth in the geographic extension of markets, which suggests that networking sustains long-term objectives of the firms.     

Optimal Timing of Climate Change Policy: Interaction Between Carbon Taxes and Innovation Externalities

This paper addresses the impact of endogenous technology through research and development (R&D) on the timing of climate change policy. We develop a model with a stock pollutant (carbon dioxide) and abatement technological change through R&D, and we use the model to study the interaction between carbon taxes and innovation externalities. Our analysis shows that the timing of optimal emission reduction policy strongly depends on the set of policy instruments available. When climate-specific R&D targeting instruments are available, policy has to use these to step up early innovation. When these instruments are not available, policy has to steer innovation through creating demand for emission saving technologies. That is, carbon taxes should be high compared to the Pigouvian levels when the abatement industry is developing. Finally, we calibrate the model in order to explore the magnitude of the theoretical findings within the context of climate change policy.      

Toward efficiency in the crude-oil market

The ‘official’ (OPEC) prices of crude oil before the collapse in the oil market in the mid-1980s can be interpreted as contract prices and analysed on the basis of the theory of futures (or forward) markets. This paper uses the generalized method of moments estimation technique to test for efficiency in the relationship between the official prices and the ex-post spot prices at the time of delivery. Efficiency is rejected for the sample period 1978–1985 as a whole, but evidence is found of improvements over time. Further, the GMM Wald and Hansen tests, although asymptotically equivalent, are shown to differ greatly when applied to a small sample of monthly oil price data.     

Personal attitudes in the assessment of the future of science and technology: A factor analysis approach

In 1996, the second German Delphi study (“Delphi '98”) was started. The Delphi '98 is a two-round Delphi expert survey being conducted by the Fraunhofer Institute for Systems and Innovation Research (ISI) on behalf of the German Federal Ministry of Education, Research, Science, and Technology (BMBF). The study was published in February 1998, and is now getting into its implementation phase. Its inherent focus is on the development of science and technology in 12 thematic fields in the next 30 years. To arrive at a better understanding of the influence of personal attitudes towards general developments in natural environment and society, the respondents were asked in the first round of the Delphi survey for their personal opinion towards several megatrends concerning the natural environment, economic, sociological, and political developments. Over 2,300 answers led to a very solid database, which gives insights into the general attitudes of the German R&D experts. On some topics, there is a high consensus, whereas in others, opposite opinions coexist. These results may serve as the database for a factor analysis leading to the identification of five different expert types. This paper examines the crucial question of whether different patterns in assessing the future development in science and technology by expert types can be observed. In general, it turned out that differences in personal attitudes towards megatrends do not influence the estimation of developments in science and technology. However, differences exist in specific topics and the distribution of the five experts types among the respondents differs significantly in the 12 fields.     

Explanatory factors for participation in formal standardisation processes: Empirical evidence at firm level

In contrast to the long tradition of empirical research into the innovation activities and R&D collaboration of companies, the issue of standardisation has been analysed mostly in theoretical approaches. This paper presents an empirical analysis of the participation of German companies in formal standards development organisations. It becomes clear that company size has a significant positive effect on the probability of a participation in standardisation. We focus further on two aspects, on R&D as input and export intensity as performance indicator, in order to explain the likelihood to join formal standardisation processes. Both the R&D intensity and the export activities exhibit an inverse U relationship. Obviously, even participating in standardisation processes requires a certain absorptive capacity, but R&D and export intensive companies expect more disadvantages, like unintended knowledge spill-overs, from joining formal standardisation processes and, therefore, stay away. In addition, export activities increase the likelihood to join formal standardisation processes up to a certain level, although companies with very high export shares expect less benefit from joining formal standardisation processes. Finally, some policy conclusions are derived.

Firm Size and Wages in Germany – Trends and Impacts of Mobility

The analysis of firm-size wage differentials in Germany, using data from the German Socio-Economic Panel, firstly corroborates the finding that wages rise with firm-size and shows that the rank order of mean wages between firm-size classes is stable for the period 1984–1993. Secondly, the most important novel results are as follows: (i) wage differentials between firm-size classes increased during the period investigated after controlling for individual attributes and computing with deflated values; (ii) average levels of the qualification of employees have diverged noticeably between small and large firms; (iii) movers from small to larger firms have to accept wages below the average pay of incumbents with comparable attributes in the new firms: (iv) movers to smaller firms, however, retain a portion of their higher wages in larger firms; and (v) wage differentials between smaller and larger firms decline with increasing unemployment.     

Egalitarian Wage Policies and Long-Term Unemployment

How does a centrally imposed egalitarian wage policy affect unemployment, when workers differ with respect to productivity? The effect on total unemployment is found to be ambiguous. Egalitarian wages encourage job creation because increased profits derived from the most productive workers more than outweigh reduced profits derived from the least productive workers. Short-term unemployment is reduced. On the other hand, firms respond by raising their reservation productivity. Some workers are left almost completely unemployable. Long-term unemployment rises. Less inequality in the wage distribution is obtained at the expense of more inequality in the distribution of unemployment.     

Office location decisions, modal split and the environment: the ineffectiveness of Norwegian land use policy

An examination of five Norwegian companies’ decisions to locate/relocate reveals that the new locations are in accordance with policy objectives of reduced car commuting and related environmental improvements. Still, most companies ended up with new locations that increase car commuting significantly, compared both to the situation before relocation and to the alternative location that was eliminated only at the last stage in the selection process. This paradox may be explained by a double policy failure: First, current policy instruments are not oriented towards the parameters that companies themselves consider as key selection criteria for office location. Second, policy instruments do not adequately address factors that determine the share of car commuting for a given location.
