Choices of television programs is viewed as a process of deciding among a set of alternative goods with zero prices. A choice model can thus be based purely on individuals' preferences for various characteristics of a set of shows available, incorporating the option of not watching if all shows are too dissimilar to these desires. The shows are first grouped according to salient characteristics and a preferred value for each characteristic is estimated for each potential viewer. A perceived position of each show is similarly estimated and watching is shown to decline as similarity between preferred show and available alternatives declines. The choice model predicts show choice better than simpler models based on aggregate audience measures or on network loyalty, but the explanatory power is weak; some suggestions for improvement are made. 相似文献
Recent research has provided important insights on consumers’ preferences for prepayment mechanisms and on its impact on consumption of a given product or service. However, little is known about how prepayment influences future purchases of goods and services. We consider this question in a contractual setting within the services industry, involving different purchasing decisions over time. Based on a large-scale empirical test, we find that prepay customers make fewer changes to their cross-buying levels (i.e., the number of different services they buy from the company) from one contractual period to another, and that this effect is more salient for the firm's new customers. We propose possible explanatory mechanisms for this effect. For instance, based on mental budgeting theory, we suggest that prepayment customers may set mental budgets and track expenditures against this budget leading them to resist further investments. Alternatively, prepayment customers may be more certain about their consumption behavior leading to fewer changes over time.
A model of how institutional investors evaluate and allocate business to brokers shows a complex pattern of influences. The broker's ability to execute transactions at appropriate prices is basic, but this combines with research and sales force performance to build a relationship that affects over-time allocation of business. It is difficult to separate relationship and selling performance, and relationship is subject to considerable decay. Research ability has a weak effect on business allocated on the basis of trading, while trading ability does affect business allocated on the basis of research. 相似文献
This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself. 相似文献
