The aim of this study is to analyse whether the receipt of public R&D funding determines firm's R&D strategy selection. This issue is crucial, as previous studies have shown that each R&D strategy is associated to a higher, or lower, innovation performance. We consider three R&D strategies – make, buy, make–buy – and three different sources of public funding – regional, state and other (such as EU). The model estimation is performed through a multinomial logit model with random effects with a sample of 457 large firms for the period 1992–2005, taken from the Spanish Survey of Business Strategies. The main finding is that the source of the funding influences whether firms select the make, buy or make–buy strategy. Additionally, because of the panel structure of the sample, we observe that the effect of public funding on the R&D strategy selection lasts longer for state and regional funds than for other funds. 相似文献

We estimate the pass-through from market interest rates to bank interest rates using heterogeneous panel cointegration techniques to address heterogeneity at the bank level in the Czech Republic. The results indicate heterogeneity in bank pricing in the short, but not in the long term. Mortgage rates and firm rates typically adjust to money market changes, but often less than fully in the long run. Large corporate loans have a smaller mark-up than small loans. Consumer rates have a high mark-up and do not exhibit a cointegration relationship with money market rates even in the long run. Next, we examine how bank characteristics determine the nature of interest rate pass-through in a cross-section of Czech banks. We find evidence for relationship lending, as banks with a stable pool of deposits smooth interest rates and require a higher spread as compensation. Large banks are not found to price their products less competitively. Greater credit risk increases vulnerability to money market shocks. 相似文献

The aim of this paper is to review the usefulness of the software CAQDAS QSR—Nvivo-6 in a PhD. Thesis, which consisted of
finding the long-term psychological effects of experiences of imprisonment and torture for political reasons in their Chilean
survivors. For this research, it was created and administered an in-depth interview to 60 survivors, from which outcome was
9900 paragraphs, coded into 784 categories. The software QSR Nvivo-6 threw a report of frequencies, which were compared quantitatively
using Pearson’s χ
2 square test and cluster analysis. We conclude that the software facilitates the development of qualitative thematic content
analysis, simplifying the coding, analysis and display of data. In Addition, it is very useful when working with large quantities
of information, promoting the reliability and validity of studies. However, other aspects are also required to ensure the
rigor of a qualitative study. 相似文献

Electronic commerce (EC) is not new for some European Union countries, but in others, such as Spain, it is only at the developmental stage. Now that Spain has joined the third phase of the economic and monetary union, Spanish companies' internationalization and the progressive change in the Spanish consumers' buying habits are determining the search for new business strategies. Starting with an analysis of the Spanish business environment, followed by an internal scanning of small and midsized Spanish companies, this paper will analyze the viability of EC as a new business strategy. 相似文献

The number of social media posts that expose company integrity violations has increased dramatically. In response, some companies empower employees to respond to customer blogs, which requires employees to recognize the customer's perspective. We show that attentional bias modification can be used to prime employees of two global Fortune 100 companies with a self-sufficiency or empathy bias. The results indicate that narrative transportation, or the extent to which employees mentally enter the world evoked by a customer's story, mediates the effect of attentional bias on two relevant psychological ownership dimensions: acknowledgment of responsibility and willingness to respond. Participants with a self-sufficiency bias neither acknowledge responsibility nor want to respond. However, participants primed with an empathy bias take responsibility for the customer's case and respond to the integrity violation. We find evidence for two boundary conditions of this effect: (1) it strengthens when the employee perceives the customer's financial vulnerability as high and (2) it weakens when the customer is impolite in the blog post. 相似文献

Empirical research has recently paid considerable attention to the role of environmental factors in explaining regional variations in entrepreneurial activity. However, cognitive models have not usually included these factors in their analyses. Therefore, the main objective of this study is to identify some of the environmental cognitive elements that may explain regional differences in start-up intentions. Thus, an entrepreneurial intention model is developed, theoretically based on the planned behaviour approach, institutional economic theory and social capital theory. The empirical analysis is carried out using structural equation techniques over a sample of 549 final year university students from two Spanish regions (Catalonia and Andalusia). Results confirm that valuation of entrepreneurship in each region helps explain regional differences in entrepreneurial intentions. As expected, social valuation of the entrepreneur was higher in the more developed region (Catalonia), positively affecting perceived subjective norms and behavioural control. In Andalusia, the influence of perceived valuation of the entrepreneur in the closer environment was more important, affecting attitude towards the behaviour and subjective norms. These results explain some of the differences in the pool of potential entrepreneurs in each region. They also justify the need by public-policy decision-makers to promote more positive entrepreneurial values in relatively backward regions. 相似文献

Most transition countries used tax‐supported wage norms in the early 1990s, as a part of their market liberalization programmes. This article analyses how a firm‐level tax (or subsidy) on deviations from a pre‐set wage norm may promote employment by rotating the labour demand curve perceived by the workers’ union around the value of the norm. We derive the conditions under which it yields a positive employment effect. We test the effect of the norm on the wages on a sample of Polish firms in 1990 and 1991. The data support the role of the wage norm on the position of the perceived labour demand curve and the role of the tax rate on its slope. 相似文献

Federally regulated or insured lenders in the United States are mandated to require flood insurance on properties that are located in areas at high risk of flooding. Despite the existence of this mandatory flood insurance requirement, take‐up rates for flood insurance have been low, and the federal government's exposure to uninsured property losses from flooding remains substantial. Meanwhile, the value of capital at risk varies significantly with flood events and changing risk perceptions, which necessitates mechanisms that stabilize these dynamics. In this article we discuss how a scenario of complete insurance uptake, under various risk attitudes, affects the value of properties in the 100‐year and 500‐year flood zones. Our results indicate that an increase in flood insurance uptake may provide such a mechanism by lowering the value of capital at risk in the flood zone consistently, independent of homeowners' risk attitudes. We apply an empirical adaptive agent‐based model to examine the capitalization of insurance costs, risk premiums, and their interaction in housing prices. Our approach combines widely‐used empirical hedonic analysis with the computational economic framework. We highlight the usefulness of our method in capturing the marginal implicit price of homeowners' preferences that may change over time and separately assess the effect of various factors and policies on property values, illustrating the agent‐based modeling as a valuable complement to traditional hedonic analysis. 相似文献
