To foster R&D activities, German industry lobbyists and policymakers are discussing the introduction of tax incentives for R&D in small and medium enterprises (SME) — all the more because Germany is one of just six of the 35 OECD members without indirect R&D support. Based on a critical assessment of the arguments provided, we conclude that international experiences with R&D tax incentives are not as promising as often suggested. An appropriate transfer into the German tax system, considering its specificities, appears to be technically difficult. The high level of heterogeneity of German SMEs population suggests that not every SME requires R&D to be innovative, because empirical evidence shows multiple diverse innovation patterns that demand other forms of support. Acknowledging the existing range of SMEs, we propose that instead of introducing R&D tax incentives, the debate should be focused on how to strengthen and develop the existing innovation policy mix for SMEs. 相似文献

The empirical finding that exporting firms are more productive on average than non‐exporters has provoked a large theoretical literature based on models such as Melitz ( 2003 ), where more productive firms are more likely to overcome costs associated with trade. This paper investigates how closely the productivity heterogeneity framework fits the data from a firm‐level survey that includes information on export destinations and firm characteristics such as productivity. We find a high degree of unpredictable idiosyncratic participation in export markets by firms and a relatively weak positive correlation between the extent of a firm's export market participation and its export sales. We find that a small number of standard gravity variables provide a close fit to the country‐level determinants of trade but that greater variation results in more difficulty in explaining firm‐specific factors driving exporting behaviour. We also illustrate some elements of the dynamics over time in firm exporting patterns by destination. We show that lagged exporting activity has a significant effect on a firm's current exporting profile. 相似文献

Urgent issues such as climate change have drawn increasing attention from finance scholars. Most research has situated a corporate response within the context of the environmental, social and governance performance. However, other disciplines express concerns around environmental degradation within broader frameworks, such as the Planetary Boundaries framework. We highlight the different conceptualisations of ESG and planetary boundaries and call for further research that links finance research to the Planetary Boundaries framework. We describe how contributions in the Accounting & Finance Special Issue on Environmental Finance advance research in this area and explore implications for future research that responds to the imperatives of remaining within Planetary Boundaries. 相似文献

This article compares empirically the several measures of individual vulnerability to poverty proposed in the literature, in order to understand which is the best signal of poverty that can be used for policy purposes. To this aim, the Receiver Operating Characteristic (ROC) curve, the Pearson and Spearman correlation coefficients are used as precision criteria. The results show that two groups of indexes can be identified, high and low performers, and, among the former, that proposed by Dutta et al. (2011) is the most precise. 相似文献

ABSTRACTThe care-less marketplace is a discrete site which reinforces structural inequality in the affective domain of life. Drawing on the work of pro-care feminist theory, this empirical paper explores marketplace exclusion from the perspective of economic disadvantage and its impact on relations of love, care and solidarity. Adopting a voice-centred-relational approach, this interpretative study examines the narrative accounts of a diverse group of women living in diverse poverty contexts. Articulating marketplace exclusion as a series of affective burdens, material struggles and disconnections embedded within the relational web of family, friends and community – these experiences mirror participants’ imposed exclusion in the marketplace due to chronic economic hardship. Through the diffusion of an alternative theoretical lens, affective inequality surfaces the importance of care and how it is often most visible in the lives of vulnerable consumers when it is absent or broken. 相似文献

Based on an analogy to the physical phenomenon of Brownian motion, Venkatesh Padmanabhan and Wm. E. Souder present a general purpose model to assist in the successful transfer of newly developed technologies. The model, named Techtran II, is successfully demonstrated with ten case studies showing how it helps managers develop a priori intervention strategies for improving transfer likelihoods. The results suggest that Techtran II can assist in overcoming problems in successful new product development, commercialization, transfer and user adoption. The Techtran II computer program is available to interested users and researchers. 相似文献

In this paper we examine the valuation effects and long–term performance of US multinational firms involved in forced transfers of their foreign operating assets during the 1965–88 period. The evidence suggests that the operational hedging ability of the firm to address country risk (nationalization threats) is related to the level of its intangible assets. While it is well known that firms with high levels of intangible assets prefer foreign direct investment, our results show that intangible assets have hidden properties of protection against country risk as well. We document significantly negative abnormal returns only for divesting firms with low levels of intangible assets, but not for firms with high levels of intangible assets. In addition, we show that low (high) growth firms are involved in partial (complete) withdrawals, and show that the long–term economic performance of firms choosing the complete withdrawal strategy is better than those that opt to remain. We argue that management's attempt to maintain economic links in a hostile foreign environment can be attributed in part to the firm's low growth opportunities, performance, and lack of contingent plans to address country risk. 相似文献

This paper investigates conditional return distribution characteristics for seven developed markets (DMs) and eight emerging markets (EMs). With the exception of Germany and Japan, the behavior of monthly returns of DM sample countries is similar to that of the U.S. In contrast, EM returns exhibit a substantially greater degree of serial correlation and a higher incidence of autoregressive conditional heteroskedasticity (ARCH) in monthly data. Aggregation of returns into two- and three-month holding periods decreases the significance of the ARCH effects. However, there are cross-sectional differences in the rate at which ARCH effects become insignificant. The findings of ARCH in monthly returns sample data is attributed to differences in the rate at which information arrives and is transmitted into prices in each market. 相似文献
