Innovative industries are often characterized by rapid product turnover. Product longevity may be driven by both a product's position within a market as well as its position within a firm's larger product portfolio. However, we have little understanding of the relative importance of these factors in determining product turnover and how they interact as an industry evolves. Although researchers have invested substantial effort in analyzing firm survival and turnover, there are far fewer studies of the determinants of product survival and turnover. We use hazard rate models and count regression models to describe the behavior of firms and their products with a new and detailed database on the laser printer industry. We show, first, that competition and market structure variables have a large impact on both speeding product exit and delaying product entry. Second, there is some evidence that firms that have maintained a high market share for a number of years keep their products on the market longer than those with lower market share. Finally, firms with high innovative capacity tend to enter markets frequently, but withdraw their products at average rates. Firms with strong brands tend to introduce few products and withdraw their products slowly. With these findings, the paper links product entry and exit decisions to the broader literature on firm strategic and product management. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Trade negotiations occur through time and between the governments of many countries. An important issue is thus whether the value of concessions that a government wins in a current negotiation may be eroded in a future bilateral negotiation to which it is not party. We identify rules of negotiation that serve to protect the welfare of governments that are not participating in the bilateral negotiation. Our main finding is that the two central principles of GATT/WTO—nondiscrimination (MFN) and reciprocity—preserve the welfare of nonparticipating governments and therefore offer a “first-line of defense” against bilateral opportunism. 相似文献

Some African food markets can still seem to operate inefficientlyafter price liberalisation. This seems mainly due to the existenceof significant transaction costs because of small-scale operations,and is influenced by lack of grading, deficient infrastructureand information systems. It is shown in the case of retail marketsin Kinshasa that search, supervision and other difficult-to-measuretransactions costs are more important in the margin of foodproducts than the measurable marketing costs (e.g., storage,transport). It is also shown through time series analysis thatmost of the price transmission between wholesale and retailhappens in the same week and that price asymmetry, i.e., thedifferent transmission of price increases compared with pricedecreases, is present for most products. Products characterisedby relatively more standardisation and homogeneity are shownto have lower retail margins and to behave symmetrically. Amodel based on kinked demand curves and search costs might explainthis asymmetric price behaviour. 相似文献

The Economic Freedom of North America Index (EFI) is a measure of the state-level institutional characteristics that promote economic activity. We use this index as a proxy for the degree of local market segmentation and test the hypothesis that single-state, municipal bond closed-end fund mispricing can be partially explained by a state’s EFI value. Using panel data analysis we find that EFI is significant in explaining observed variability in fund mispricing. 相似文献

Product placement provides a unique advantage over traditional advertising as it can be integrated into program content through a symbiotic relationship. A content analysis of the Billboard year-end top 20 songs for Rap, Country, R&B/Hip-Hop, Adult Contemporary, Rock, and Pop over five years (2009–2013) was conducted to determine the use of celebrities, product placement, and nonbranded product mentions in song lyrics. Results found male artists used celebrity mentions and product placement more than females, Rap contained the most mentions (73% of songs), clothing and shoes was the most prevalent product category, musicians were the most common type of celebrity mentioned, and nonbranded product mentions were in 54.5% of songs. The paper concludes by discussing practical implications of utilizing branded, nonbranded, and celebrity mentions in song lyrics. 相似文献

Background:Hospitalized patients with complicated skin and soft tissue infections (cSSTI) present a substantial economic burden, and resource use can vary according to the presence of comorbidities, choice of antibiotic agent, and the requirement for initial treatment modification. REACH (NCT01293435) was a retrospective, observational study aimed at collecting empirical data on current (year 2010–2011) management strategies of cSSTI in 10 European countries.Methods:Patients (n?=?1995) were aged ≥18 years, hospitalized with a cSSTI and receiving intravenous antibiotics. Data, collected via electronic Case Report Forms, detailed patient characteristics, medical history, disease characteristics, microbiological diagnosis, disease course and outcomes, treatments before and during hospitalization, and health resource consumption.Results:For the analysis population, mean length of hospital stay (including duration of hospitalizations for patients with recurrences) was 18.5 days (median 12.0). Increased length of hospital stay was found for patients with comorbidities vs those without (mean?=?19.9; [median?=?14.0] days vs 13.3 [median?=?8.0] days), for patients with methicillin-resistant Staphylococcus aureus compared with patients with methicillin-sensitive S. aureus (mean?=?27.7 [median?=?19.5] days vs 18.4 [median?=?13.0] days) and for patients requiring surgery (mean?=?24.4 [median?=?16.0] days vs 15.0 [median?=?11.0] days). Patients requiring modification of their initial antibiotic treatment had an associated increase in mean length of hospital stay of 10.9 days (median?=?6.5) and additional associated hospital resource use. A multivariate analysis confirmed the association of nosocomial infections, comorbidities, directed treatment, recurrent infections, diabetes, recent surgery, and older age (≥65 years), with longer hospital stay.Conclusions:This study provides real-life data on factors that are expected to impact length of hospital stay, to guide clinical decision-making to improve outcomes, and reduce resource use in patients with cSSTI. 相似文献
