RESEARCH AND DEVELOPMENT IN SMALL AND MEDIUM-SIZED ENTERPRISES: THE ROLE OF FINANCIAL CONSTRAINTS AND PUBLIC FUNDING 总被引:7,自引:0,他引:7
Dirk Czarnitzki 《Scottish journal of political economy》2006,53(3):335-357
This paper presents microeconometric evidence on financing constraints for research and development activities in German small‐ and medium‐sized firms (SME). Special attention is paid to the role of public research and development (R&D) subsidies. For this purpose SMEs in West and East Germany are compared because these regions are very different in their supply of public R&D funding. The empirical evidence suggests that West German SMEs are financially constrained in their R&D activities by both internal and external resources. In East Germany, firms are not sensitive to external constraints, possibly due to high public R&D subsidies. The results show that R&D in East Germany is to a large extent driven by public subsidies and that the usual financial market mechanisms are dysfunctional with respect to R&D in this region. 相似文献

The purpose of this paper is to investigate the impact of externalities on pricing decisions by a public or a private regulated firm selling both final and intermediate goods. The externalities generate feedbacks in demand that affect both consumers and producers. The model is very general in that it does not impose constant returns to scale on private production, allows for distributional effects of both the publicly determined prices and private sector profits, and captures the general equilibrium effects of public pricing. Socially optimal pricing rules are derived, and the relation of the results with previous models of pricing in the presence of externalities is investigated. 相似文献

Der Beitrag vermittelt einen grundlegenden überblick über die Bedeutung des Vertrauens im Rahmen der ?konomischen Theorie.
Zun?chst werden ausgew?hlte Ans?tze im Rahmen der betriebswirtschaftlichen Vertrauensforschung diskutiert. Um eine strukturierte
Analyse zu erm?glichen, erfolgt eine differenzierte Betrachtung hinsichtlich der neoklassisch und institutionen?konomisch
fundierten Perspektive einerseits sowie der sozio?konomischen Perspektive andererseits. Die Diskussion um den Stand der Forschung
wird abgerundet durch einen überblick über empirische Ergebnisse der ?konomischen Vertrauensliteratur. Um noch offene Fragen
im Rahmen der Forschung zu adressieren, werden im Anschluss die unterschiedlichen Objekte des Vertrauens analysiert, differenziert
nach personalen Vertrauen und Systemvertrauen. Zum Abschluss gilt es die Verhaltensrisiken herauszuarbeiten, die mit Vertrauensbeziehungen
einhergehen und die Grenzen des Vertrauens in Organisationen zu beleuchten. 相似文献

This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis
is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals
that the development over time of the cross-country variation in productivity performance differs across sectors as well as
across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation
of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis
that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity.
Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific
steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively.
We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization
play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.

This paper presents a simple model which illustrates the possible policy- and welfare-implications of endogenous product selection in the postal sector. The cost of a unit of mail depends on its "quality" (e.g., speed of delivery) and on the type and location of the addressee (firms, urban households, and rural households). Senders have inelastic demands and differ in their willingness to pay for quality. Addressees are passive but their utility may affect social welfare. Two operators play a two-stage game, first choosing qualities and then prices. We first show that the equilibrium with two private (profit maximizing) operators results in an inefficient provision of quality. Then, we consider the mixed (Nash) equilibrium with one private and one (welfare maximizing) public operator. If the budget constraint of the public firm is not binding, this equilibrium is shown to be first-best efficient even if social welfare accounts for the utility of addressees. If the budget constraint is binding, the mixed equilibrium is not efficient but yields a higher level of welfare than the private equilibrium. Finally, we study the impact of minimum quality standards within our setting. 相似文献

An analysis of the impact of migration to the United States on the sending community and on the labor market in the receiving country is presented based on a case study of Las Animas, Mexico. "As the community becomes increasingly involved in migration, tendencies can be identified regarding changing migration patterns, class differentiation among villagers, impact of migration on village economy, and the changing role of Mexican workers in California labor markets. Results indicate the importance of social networks in determining the outcome of migration; while migration is individually rational, it is a factor of stagnation for village economy, and it helps reproduce segmented California labor markets." 相似文献

In analyzing firm entry and exit across Belgian manufacturing industries, this paper presents evidence that import competition and foreign direct investment discourage entry and stimulate exit of domestic entrepreneurs. These results are in line with theoretical occupational choice models that predict foreign direct investment would crowd out domestic entrepreneurs through their selections in product and labor markets. However, the empirical results also suggest that this crowding out effect may be moderated or even reversed in the long-run due to the long term positive effects of FDI on domestic entrepreneurship as a result of learning, demonstration, networking and linkage effects between foreign and domestic firms. 相似文献
