More than a year after a court invalidated its “net neutrality” rules on broadband Internet service providers (ISPs), the Federal Communications Commission (FCC) decided to extend public-utility (Title II) regulation on broadband services. This paper uses traditional event analysis of the movements in the values of major communications and media companies’ equities at key moments in the FCC’s path to this decision to estimate the financial market’s assessment of the likely effects of regulation on ISPs, traditional media companies, and new digital media companies. The results are surprising: the markets penalized only three large cable companies to any extent, and even these effects appear to have been short-lived. The media companies, arguably the intended beneficiaries of the regulations, were unaffected. 相似文献

This study examines vertical integration in the Japanese movie industry. I estimate an admission price equation, and a moviegoing
demand equation derived from a discrete choice model of product differentiation. In order to overcome identification problems,
this study exploits a panel structure dataset. My results show that the price of vertically integrated theaters tends to be
higher than nonintegrated theaters, but it appears to be due to the inherent high quality of vertically integrated theaters.
On the other hand, vertically integrated theaters are more popular among consumers and have higher attendance than nonintegrated
theaters. Even after controlling the theater fixed effects, attendance for vertically integrated theaters is still larger
than nonintegrated theaters. That is, the integration of producers/distributors and theaters is likely to be a source of economic
efficiency. Policy implications are also proposed. 相似文献

Patientenindividuelle Verblisterung - Eine hohe Arzneimittelsicherheit für Patienten, Bewohner und Pflegende, therapiegerecht
und lückenlos dokumentiert – verblisterte Medikamente erleichtern nicht nur die Compliance und verbessern somit die Heilungschancen
von Patienten. Das Pflegepersonal profitiert gleicherma?en. Denn es bleibt ihm mehr Zeit für die individuelle Betreuung der
Bewohner. Das zumindest versprechen die Blisterzentren. 相似文献

Using data aggregated from seven papers that study repeated play in standard ultimatum games with either stranger or absolute
stranger matching, we show that the behavior of responders changes with experience. High offers are more likely to be accepted
with experience and low offers are more likely to be rejected. At the individual level, there is a negative relationship between
the likelihood that a given offer is accepted and the size of the preceding offer. We compare the results with predictions
generated by static models of distributional preferences, implicitly dynamic models of preferences with reciprocity, and explicitly
dynamic models of adaptive learning. The data is most consistent with models of preferences with reciprocity. 相似文献

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield,
concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance
analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are
used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes
or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or
impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the
main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division
of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric
technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR.
It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future
research could lead. 相似文献

This paper investigates pricing issues in class-based networks. Classes of packets having lower impatience and longer average
delay receive monetary compensations. The inter-class price differential is determined by the inter-class compensations. The
paper also presents rules for allocating network resource to each class. The corresponding payoff (disutility share) for each
class is driven by the Shapley Value of the associated cooperative game. 相似文献

We use daily price data from the Egyptian stock market and a Loser portfolio of 20 IPOs from the late 1990s that experienced
dramatic 1-day price falls in the period 2004 to 2007 to estimate a 2-way fixed effects model of CARs. Observable covariates
are company size and turnover growth and unobservables company and period fixed effects. Our results provide evidence of significant
price reversal over the first 40 post-event days. Firm size is negatively correlated with post-event CARs, consistently with
the argument that small firms have a stronger tendency to price-reverse due to greater informational opacity. But permanent,
unobservable company-specific factors, account for a much larger percentage of post-event variation in stock prices and indicate an underlying
heterogeneity in investor responses to initial price falls not uncovered before in the literature. Strong negative company
effects following a price fall are found to presage reinforcing ‘long term’ price falls and strong positive company effects to presage countervailing ‘long term’ price reversals. At the extremes these company effects are sufficiently large to suggest that a trading strategy
based on them would be profitable. 相似文献
