This paper examines one of the fastest growing industries in our world today, the ICT industry. We assess the sensitivity of a firm’s investment to a set of financial determinants, by developing a flexible adjustment dynamic model. In particular, we examine the degree to which a firm’s liquidity influences firm investment and whether firm size and firm specialization have any additional implications. Moreover, the effect of the dot-com burst is also considered. For a panel of ICT and non-ICT US companies listed on the NASDAQ stock exchange, the results reveal the following: (1) all firms are sensitive to the availability of internal funds; (2) investment intensity decreases with firm size; (3) and leverage negatively affects investment for ICT firms.  相似文献

This article presents the methodology and results for measuring the knowledge intensity of manufacturing industries based on the knowledge-related characteristics of their workforce. The measures link information from the Occupational Information Network project (from the US Department of Labor) and the Occupational Employment Statistics (from the Bureau of Labor Statistics) to produce industry-specific knowledge intensity measures. The new measures overcome the main issues posed by the industry-average R&D share in total sales variable, often used as a proxy for knowledge intensity in the literature.  相似文献

Stores develop customized assortments based on localization characteristics. In terms of performance analysis, these changes make it more difficult to analyse store performance. This adjustment procedure entails an internal benchmarking which needs small samples to control regional and assortment effects. This paper explores the influence of competitive environment and store neighbourhood characteristics on store efficiency by using three data envelopment analysis (DEA) models. This research is illustrated by using real data from a French supermarket retail chain at the product category level. It is shown that the two-steps DEA model is a relevant analysis tool to take into account location aspects. It presents a discriminant power strong enough to derive managerial implications with small samples.  相似文献

Objectives:

Atazanavir (ATV) and darunavir (DRV) are protease inhibitors approved for HIV treatment in combination with ritonavir (/r). The objectives of this study were to compare persistence (time to treatment discontinuation/modification), adherence, and healthcare costs among patients with human immunodeficiency virus (HIV) initiating ATV/r or DRV/r.

Methods:

This retrospective cohort study used commercial and Medicaid administrative insurance claims data. Patients initiating ATV/r or DRV/r from 2006–2013 with continuous enrollment for ≥6 months before and ≥3 months after initiation were included. Patients were followed from initiation until discontinuation/modification (≥30 day gap in ATV or DRV or initiation of a new antiretroviral medication), during which time adherence (proportion of days covered [PDC], with PDC ≥80% or 95% considered adherent) and per-patient per-month (PPPM) total healthcare costs were measured. DRV/r patients were propensity score matched to ATV/r patients at a 1:1 ratio to achieve balance on potentially confounding demographic and clinical factors. Commercial and Medicaid samples were analyzed separately, as were antiretroviral (ART)-naïve and experienced patients.

Results:

The final samples comprised 2988 commercially-insured and 1158 Medicaid-insured patients. There were no significant differences in hazards of discontinuation/modification between the ATV/r or DRV/r cohorts. With respect to odds of being adherent, the only marginally significant result was comparing odds of achieving PDC ≥80% among ART-naïve Medicaid patients, which favored ATV/r. All other adherence comparisons were not significant. Although ATV/r cohorts tended to have lower PPPM costs, the majority of these differences were not statistically significant.

Conclusions:

Patients with HIV treated with either ATV/r or DRV/r had similar time to treatment discontinuation/modification, adherence, and monthly healthcare costs. Results were similar across the pre-specified sub-groups. These findings are useful not only as an insight into clinical practice, but also as a resource for healthcare providers and payers evaluating treatment options for HIV+ individuals.  相似文献

Increasingly, govemments and firms take clusters of related business as a starting point to formulate policies and strategies, which aim at enhancing innovation. There appear, however, to be quite some different conceptions of what clusters are, In the first part of this paper and attempt is made to clarify the cluster concept by defining the relevant dimensions of clusters. In the second part, each of these dimensions is related to possible industrial policies and firm strategies. Practical illustrations will be given from different European countries and firms. The dimensions and related policies and strategies form a menu of possibilities from which actors can choose those elements that are most relevant for their specific situation. Thus, tailor-made policies and strategies can be devised and implemented.  相似文献
