Most studies indicate Hollywood's economic and financial leadership in the movie markets from the 1910s onward. There is a shortfall in the literature concerning the analysis of the efficacy of other minor film industries. This article examines the Italian film industry in the 1990s and beginning of the twenty‐first century. The research suggests that the Italian film industry is very risky and unpredictable, but while the extreme uncertainty surrounding the business is offset by the considerable economic success that Hollywood movies achieve at the box office, as indicated by previous literature contributions, a different business scenario emerges in Italy. The value of this article is first represented by the data used—provided by the Osservatorio of Cinecittà—which is unique and has not been published before. © 2016 Wiley Periodicals, Inc.  相似文献

The productive and allocative theories predict that education has positive impact on health: the more educated adopt healthier life styles and use more efficiently health inputs, and this explains why they live longer. We find partial support for these theories with an econometric analysis on a large sample of Europeans aged above 50 documenting a significant and positive correlation among education years, life styles, health outputs and functionalities. We however find confirmation for an anomaly already observed in the United States, namely the more educated are more likely to contract cancer. Our results are robust when controlling for endogeneity and reverse causality in IV estimates with instrumental variables related to quarter of birth and neighbours’ cultural norms.  相似文献

In this article, I try to answer three questions: (1) How do relationship lending and transaction lending vary over the cycle? (2) How do economic systems that are more “bank oriented” perform compared to “market-oriented” systems? (3) What are the consequences on relationship banking of the recent structural bank regulation reforms adopted to separate specific investment and commercial banking activities? Building on some recent evidence, the main conclusions are as follows: (1) Relationship banks protect their clients in normal downturns; (2) when recessions coincide with a financial crisis, countries that rely relatively more on bank financing tend to be more severely hit; (3) the effects of structural bank regulation initiatives on relationship banking are uncertain.  相似文献

We compare two instruments to regulate a monopoly that has private information about its demand or costs: fixing either the price or quantity. For each instrument, we consider sophisticated (screening) and simple (bunching) mechanisms. We characterize the optimal mechanisms and compare their welfare performance. With unknown demand and increasing marginal costs, the sophisticated price mechanism dominates that of quantity, whereas the sophisticated quantity mechanism may prevail when marginal costs decrease. The simple price mechanism dominates that of quantity when marginal costs decrease, but the opposite may arise if marginal costs increase. With unknown costs, both instruments are equivalent.  相似文献

Objective: The objective of this analysis was to estimate the relative cost-effectiveness of Actikerall1 (5-FU-SA) vs cryotherapy in a secondary care setting in the UK, for lesion-directed treatment in patients with actinic keratoses (AK) of the face and scalp.

Methods: The model was a simple decision tree, with a 6-month time horizon. The perspective was that of the UK National Health Service (NHS). Modeled treatment effects included reported per-patient histological clearance and recurrence rates. Cost inputs comprised professional consultation time and cost of medication. Health-related utility estimation followed previously published methodology. Adverse events were not modeled. The key data and model structural assumptions followed expected UK practice. One-way and probabilistic sensitivity analyses were conducted to assess structural and parameter uncertainty.

Results: 5-FU-SA was found to be less costly (?£204) and more effective (+0.001 QALY) in base case and sensitivity analyses. In the probabilistic analysis there was 100% probability of being cost-effective over cryotherapy at £20,000 willingness to pay. Cost of professional time was a key driver of the model outcome. 5-FU-SA remained dominant across a range of scenario analyses, including exploration of assumptions around setting of care.

Limitations: The time horizon of the analysis was short and data were not extrapolated beyond the duration of the clinical trial; however, this approach is consistent with likely follow-up of an AK patient. The clinical outcomes observed in the trial were based on a large proportion of cryotherapy patients undergoing an additional cycle of treatment; this may not occur or be required in an experienced secondary care setting.

Conclusion: 5-FU-SA could be considered as a cost-effective choice for treatment of AK lesions of the face and scalp in secondary and mixed care settings in the UK. Use of 5-FU-SA in patients who would otherwise be managed with cryotherapy has the potential to result in cost savings.  相似文献

This study investigates how knowledge diffusion occurs in a globally dispersed supply network, wherein buying firms and suppliers often do not have strong relationships and competitive tensions prevail. We elaborate the Network of Practice (NoP) view by examining a global supply network in the food sector that is as an exemplar of high global dispersion. This paper provides several novel insights into global knowledge diffusion. We introduce the NoP concept of homophily into the field of supply chain management to explain knowledge diffusion within global supply networks. We take a longitudinal perspective to show that although prior contractual ties (relational homophily) and co‐location (location homophily) initially drive knowledge diffusion, in the long‐term, shared practices (practice homophily) are the principal driver of knowledge diffusion. We demonstrate that buying firms’ assurance of procedural justice, together with the predominance of geographically dispersed suppliers and the emergence of nexus members, can help dampen supplier resistance to knowledge diffusion. The study shows that knowledge diffusion in a global supply NoP occurs in two complementary forms—broadcasting forums and action groups—which vary in breadth, depth, and tie diversity. Ultimately, we present vertical (buyer‐supplier), horizontal (suppliersupplier), and diagonal (non‐competitive) relationships as important refinements of the NoP view that characterize a global supply NoP. Overall, our findings offer a path for buying firms to establish adequate online infrastructure to support the emergence of decentralized and self‐organized knowledge diffusion in a globally dispersed supply network.  相似文献
