The internationalization of firms from emerging markets has been studied mainly from the perspective of large firms. Smaller and younger international firms based in emerging markets suffer from underrepresentation in the literature. This study sheds light on the internationalization of emerging market SMEs, focusing on Colombian textile and apparel exporters. Using mixed research methods, it illustrates the role of firm age in influencing internationalization strategy. It examines 1165 export contracts by 50 SMEs, discussing export intensity, speed, and geographic scope using recurrence analysis and cluster analysis. It contributes to international entrepreneurship by exploring new empirical evidence and examining it using a novel methodological approach.  相似文献

This article assesses the possibilities of using consumer innovation in the electricity sector, which is slow‐moving, yet faced with huge challenges and opportunities to become “smart” and “low carbon.” We study the benefits of engaging innovative consumers (“lead users”) in product, service, and business innovation in terms of (a) the capacity of lead user‐consumers to innovate in the highly regulated electricity market, (b) the attractiveness of such lead‐user generated ideas for mainstream consumers, (c) the usefulness of lead‐user engagement for companies in the energy industry, and (d) the usefulness of lead user engagement for the necessary broader societal transition processes. We conclude that consumers can stimulate industry‐wide innovation even in challenging contexts like “smart” and “low‐carbon” solutions and the highly regulated energy industry. Lead user‐consumers can also articulate societal and social responsibility concerns that are relevant for the entire market.  相似文献

Based on the theory of organizational design and on the theory of knowledge, this paper analyzes how the traditional variables which define a firm's organizational structure (formalization, complexity, and centralization) influence knowledge performance (the degree to which a firm generates knowledge internally and uses it to reach a competitive advantage). The paper tests three hypotheses using a sample of 164 large Spanish firms. The results show that organizational complexity and centralization exert a positive and a negative influence, respectively, on knowledge performance, which confirms the two hypotheses related to these variables. However, the analysis reveals no empirical evidence to confirm the hypothesis according to which formalization and knowledge performance have a positive relationship.  相似文献

Aims: To evaluate the cost-effectiveness of antimicrobial stewardship (AS) program implementation focused on critical care units based on assumptions for the Spanish setting.

Materials and methods: A decision model comparing costs and outcomes of sepsis, community-acquired pneumonia, and nosocomial infections (including catheter-related bacteremia, urinary tract infection, and ventilator-associated pneumonia) in critical care units with or without an AS was designed. Model variables and costs, along with their distributions, were obtained from the literature. The study was performed from the Spanish National Health System (NHS) perspective, including only direct costs. The Incremental Cost-Effectiveness Ratio (ICER) was analysed regarding the ability of the program to reduce multi-drug resistant bacteria. Uncertainty in ICERs was evaluated with probabilistic sensitivity analyses.

Results: In the short-term, implementing an AS reduces the consumption of antimicrobials with a net benefit of €71,738. In the long-term, the maintenance of the program involves an additional cost to the system of €107,569. Cost per avoided resistance was €7,342, and cost-per-life-years gained (LYG) was €9,788. Results from the probabilistic sensitivity analysis showed that there was a more than 90% likelihood that an AS would be cost-effective at a level of €8,000 per LYG.

Limitations: Wide variability of economic results obtained from the implementation of this type of AS program and short information on their impact on patient evolution and any resistance avoided.

Conclusions: Implementing an AS focusing on critical care patients is a long-term cost-effective tool. Implementation costs are amortized by reducing antimicrobial consumption to prevent infection by multidrug-resistant pathogens.  相似文献

The survival pattern of Swedish commercial banks during the period 1830--1990 is studied by parametric and non-parametric event-history methods. In particular we study the sensitivity of the conclusions reached with respect to the model used. It is found that the hazard is inversely U-shaped, which means that models that cannot allow for this type of hazard run into difficulties. Thus two of the most popular approaches in the analysis of event history data, the Gompertz and the Weibull models produce misleading results regarding the development of the death risk of banks over time. As regards the effect of explanatory variables on survival, on the other hand, most models are found to be robust and even in cases of misspecified baseline hazards, the estimated effects of the explanatory variables do not seem to be seriously wrong.  相似文献

Family Background and Economic Status in Finland   总被引:3,自引:0,他引:3  
The importance of family background for economic outcomes is analyzed, using a Finnish data set. The estimates for intergenerational and sibling correlations in earnings are comparatively low. By estimating the magnitude of family influence conditional on parental earnings, children with poor parents are found to have lower intergenerational elasticities, while the sibling resemblance is higher. Children with rich parents have higher intergenerational elasticities and the sibling resemblance is also higher, except for daughters. The results also indicate that the largest share of the intergenerational correlation is transmitted through observed characteristics, such as education and, in particular, occupation.

In the article are given examples showing how, by using musical notation in registering (complicated) developments, considerably more qualitative variables may be taken into account than we were used to; furthermore, the temporal element may be represented with a degree of precision that corresponds to our needs. In case of cross-sectional data modifications of musical notation may be used. However, we have to recognize that there are also variables, maybe important ones, that — for several reasons — cannot be registered with a very high precision. Other complications are hinted at. The method described is rather a working method by means of which to improve the basis for a further quantitative analysis than a method suitable for showing final research results.  相似文献
