This article discusses the limitations of present methods of analyzing the coverage of advertising schedules and presents a technique for obtaining additional information from traditional measures of schedule coverage. This technique models entire patters of audience exposure to commercials by means of a compound Bernoulli distribution that can be estimated from reach and frequency data. Knowledge of the complete pattern of audience exposure to advertising schedules assists the media analyst in selecting optimally effective advertising schedules and consequently enhances the probability of conducting a successful advertising campaign.  相似文献

This article identifies the extent to which buying environment characteristics, which are not directly related to price or product information, are currently available on online apparel websites and whether e-tail stores which use high levels of buying environment characteristics on their websites have a beneficial association with financial performance. A content analysis of 96 online apparel websites was employed. The overall extent to which current online websites provide buying environment characteristics appears to be low and providing more information in relation to the five characteristics was positively related to company profitability.  相似文献

Der fl?chendeckende Glasfaserausbau in Deutschland ist mit hohen Kosten verbunden. Insbesondere die Anschlüsse in dünn besiedelten Gebieten lassen die Kosten steigen. Die Autoren berechnen verschiedene M?glichkeiten der Kostenaufteilung.  相似文献

How do bankruptcy laws as formal institutions affect entrepreneurship development around the world? Do entrepreneur-friendly bankruptcy laws encourage more entrepreneurship development at a societal level? We posit that if bankrupt entrepreneurs are excessively punished for failure, they may give up potentially high-return but inherently high-risk opportunities to start new businesses. Amassing a cross-country database from 29 countries spanning 19 years (1990-2008), we find that lenient, entrepreneur-friendly bankruptcy laws are significantly correlated with the level of entrepreneurship development as measured by the rate of new firm entry.  相似文献

We analyse the consequences on agricultural markets of enlargement of the European Union (EU) to include the Czech Republic, Hungary, and Poland. We produce a market outlook up to 2010 for two enlargement scenarios assuming different policy restrictions on grain and dairy production in the acceding countries. Accession of the three Central and Eastern European countries (CEECs) leads to a permanent but moderate decrease in EU prices for most commodities. In the three acceding CEECs, domestic prices increase drastically, final consumption of agricultural products decreases in most instances, while production increases. Higher domestic prices in the CEECs reduce exports of most commodities to non‐union countries. Consequently, excess supplies are placed in stocks or exported to the original 15 member countries. Supply management mechanisms in the dairy and grain sectors would reduce the build‐up of surpluses in the new member states, but limit their ability to take advantage of the expanded market. Accession of the three CEECs would increase the CAP budget over its proposed maximum if area payments are extended to incoming crop producers.  相似文献

To make a pay system a source of reinforcement for contribution and give people an opportunity to participate in a reward program each year without the stigma of becoming “too expensive,” firms might consider making less than 100% of the total amount increase distributed to an individual a permanent part of his base salary. A part of the raise could be in effect for, say, a year.  相似文献

This paper develops a simple model of sequential innovations with a diversity of research lines. Competitive strategies of firms for R&D are analyzed at each stage in a sequence of innovations. We compare two alternative regimes of enforcing patent law, as a mechanism to provide adequate incentives for R&D at each stage. The regime that protects the research line gives monopoly rights to an entire line of research, hence limiting the utilization of the previous knowledge and retarding subsequent innovations. The other regime protects the product, which facilitates the use of previous knowledge at the expense of providing inadequate protection to the ideas embodied in the product, and results in underinvestment in the first stage.  相似文献

Non‐profit organizations often seek volunteers to help staff a fundraising event. In the present research, an experimental study assessed volunteering time decisions for a fundraising event following manipulations of opportunity cost valence, opportunity cost avoidability and question order involving donating time and donating money. Opportunity costs represent foregone alternatives sacrificed (e.g. working) when engaging in an activity (e.g. volunteering), with valence of the opportunity cost indicating the appeal (positive or negative) of the foregone alternative and avoidability of the opportunity cost suggesting how easy it would be to forgo the alternative. Prospective donors are often asked to consider both volunteering time and contributing money, and these two questions posed to individuals can be varied in terms of order. The results of the experiment revealed that individuals intended to volunteer the most time when an opportunity cost was negative and avoidable. The lowest time donation intentions occurred when an opportunity cost was positive and less avoidable with individuals also being asked about donating money prior to being asked to donate time. The results highlighted the importance to non‐profit firms of considering opportunity costs potential volunteers face and suggested care in structuring the order of questions involving time and money posed to those individuals.
