This paper formally investigates the factors that relate to the deviations of brand's actual loyalty levels from theoretical norms in packaged goods markets. An aggregate measure of brand loyalty, share of category requirements, commonly tracked by marketing managers is used for this analysis. The comparison is conducted against the estimated share of requirements provided by the well established Dirichlet model of purchasing behavior. We posit that a brand's positioning strategy and marketing mix can influence the magnitude and the direction of the deviation from the norm. We use a two step modeling procedure where we first compute the deviation from the norm for each brand and subsequently conduct a regression analysis of this brand-level data to test the proposed hypotheses. We find that on average, brands that cater to some market niche, are bought in higher quantities, have lower prices, promote to a lesser extent, and have shallower price-cuts and enjoy higher than expected loyalty levels. We discuss possible implications of these results and offer guidelines that managers can use to better assess both the actual and the theoretical loyalty levels of their brands.  相似文献

This article considers the neglected legacies of the Lancashirecotton industry and their impact on the U.K. outdoor trade.Studies of the decline of the Lancashire cotton industry afterthe Second World War have concentrated on the collapse of coarsecotton spinning and weaving, largely ignoring the impact ofthe knowledge and skills related to the finishing trades. Theexamination of the evolution of rainwear, coatings, and high-performancefabrics in the nineteenth century provides a backdrop to a studyof the innovation process that emerged in the U.K. outdoor tradeafter 1960. It shows that there was a path dependency betweenthe skills that resided in Lancashire’s finishing tradesand coating and fabric innovation for outdoor products. Thisarticle explores both the legacy and the ways in which the networksof innovation functioned as the U.K. outdoor trade expanded.  相似文献

Experimental analysis of choice   总被引:2,自引:1,他引:2  
Experimental choice analysis continues to attract academic and applied attention. We review what is known about the design, conduct, analysis, and use of data from choice experiments, and indicate gaps in current knowledge that should be addressed in future research. Design strategies consistent with probabilistic models of choice process and the parallels between choice experiments and real markets are considered. Additionally, we address the issues of reliability and validity. Progress has been made in accounting for differences in reliability, but more research is needed to determine which experiments and response procedures will consistently produce more reliable data for various problems.Sawtooth SoftwareDecision Research  相似文献

This paper examines the after-market for initial public offerings (IPOs), particularly the security valuation effects of structural differences in available information. There is a diversity of information among issuing firms at the time of their offering and particularly under certain market conditions. Because this diversity decreases with time and after-market trading, the IPO market provides an ideal setting for testing errors due to differential information levels in early after-market valuation of IPO firms. We find evidence that during “hot” market conditions and for firms characterized by low levels of available information, the market values of issuing firms are more likely to be overestimated in the immediate after-market. We also find positive overestimation of market values to be more likely for larger IPOs and for those marketed by the less prestigious underwriters.  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

Spending on existing housing is important not only for the building materials, building products, and construction markets but also for the macroeconomy. It accounts for about half of total spending on housing capital. The new construction, home improvement, maintenance, and repair markets use overlapping distribution channels, labor, and capital inputs. The various segments of the housing industry touch many other industries and exhibit different patterns over the course of the business cycle. Understanding the unique characteristics of these segments helps business economists and macroeconomists in planning and interpreting changes in the economy as well as estimating better forecasting models.  相似文献

Modeling Methods for Discrete Choice Analysis   总被引:2,自引:3,他引:2  
This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.  相似文献
