Decomposing the sales promotion bump accounting for cross-category effects

Extant research on the decomposition of unit sales bumps due to price promotions considers these effects only within a single product category. This article introduces a framework that accommodates specific cross-category effects. Empirical results based on daily data measured at the item/SKU level show that the effects of promotions on sales in other categories are modest. Between-category complementary effects (20%) are, on average, substantially larger than between-category substitution effects (11%). Hence, a promotion of an item has an average net spin-off effect of (20 − 11 =) 9% of its own effect. The number of significant cross-category effects is low, which means that we expect that, most of the time, it is sufficient to look at within-category effects only. We also find within-category complementary effects, which implies that competitive items within the category may benefit from a promotion. We find small stockpiling effects (6%), modest cross-item effects (22%), and substantial category-expansion effects (72%). The cross-item effects are the result of cross-item substitution effects within the category (26%) and within-category complementary effects (4%). Approximately 15% (= 11% / 72%) of the category-expansion effect is due to between-category substitution effects of dependent categories.     

中国制造的创意运动

在上世纪50年代的美国，如果你想推销产品，就要通过电视去做：早年香烟公司尤其热衷于这个新媒体，有时会获得令人惊奇的成果：国际香烟品牌“Old Gold”的广告就用了这样的一个广告：“Old Gold”牌长腿版香烟包装在布幕前翩翩起舞，再配上配音员的吟诵：“由香烟人制造，不是医生？”这当然是因为没有人想他们的香烟是由医生制造的!     

BIG QUESTIONS IN AUSTRALIAN ECONOMIC HISTORY: FROM THE OUTSIDE LOOKING IN1

The conventional story of Australian economic history is worth challenging. Rather than just assuming a national economy with conventional turning points such as Federation, economic historians would do well to investigate more complex processes like the interplay between regions, races and development, and the changing patterns of interaction with the outside world. The big question for economic historians is whether in the future they can undertake economic research which informs history and so contributes to the national debate.     

Socio-economic and demographic determinants of consumer problem perception

Studies on consumer satisfaction, dissatisfaction, and complaining behaviour provide no consistent picture of the socio-economic and demographic characteristics of the consumers involved. This study indicates that consumers with different socio-economic characteristics perceive and experience different numbers and types of consumer problems.Younger people experience more problems with commercial information. Persons of lower income and full nest families report more problems with usage costs and product quality. Problems with after-sales service are more often experienced by male and upper class consumers. Differences in problem perception may affect subsequent satisfaction, dissatisfaction, and complaining behaviour.

Sozioökonomische und demographische Einflüsse auf die Wahrnehmung von Verbraucherproblemen

Zusammenfassung Untersuchungen zur Zufriedenheit, zur Unzufriedenheit und zum Beschwerdeverhalten von Konsumenten ergeben kein konsistentes Bild der sozioökonomischen und demographischen Eigenschaften der untersuchten Konsumenten. Die vorliegende Studie deutet darauf hin, daß Konsumenten mit unterschiedlichen sozioökonomischen Eigenschaften sich hinsichtlich der Anzahl und der Art der wahrgenommenen Verbraucherprobleme unterscheiden.Jüngere Verbraucher empfinden mehr Probleme mit kommerzieller Information. Verbraucher mit niedrigerem Einkommen und Familien mit Kindern nehmen mehr Probleme mit den Gebrauchskosten und mit der Produktqualität wahr. Probleme mit dem Kundendienst treten dagegen häufiger bei männlichen Konsumenten und solchen aus höheren Schichten auf. Unterschiede in der Problemwahrnehmung wirken sich auf die Zufriedenheit und das Beschwerdeverhalten von Konsumenten aus.

A segmentation study of pedestrian weekend activity patterns in a central business district

Initiatives for the regeneration (or renewal) of Central Business Districts (CBD) could benefit from knowledge about how pedestrians interact with the environment. This study examined both cross-sectional and sequential information embedded in weekend activity patterns of pedestrians in the CBD of Hiroshima City (Japan). A multidimensional sequence alignment method was used that accounted for the types of facilities where pedestrians stopped, and whether or not stops occurred in the main street. A subsequent cluster analysis identified five distinctive pedestrian segments. The findings illustrate that, despite the complexities underlying pedestrian behavior, meaningful regularities in activity patterns can be found.     

Within-person variation in affective commitment to teams: Where it comes from and why it matters

Teamwork is crucial to organizational success and commitment to teams is an important predictor of team-related behaviors. However, theorists and researchers have typically assumed that commitment levels are generally stable within-persons, increasing or decreasing as a result of substantial organizational changes. This position is at odds with the evidence of systematic and regular intraindividual fluctuations in personal attributes and workplace behaviors. We draw upon affective events theory to present a model explaining how certain events and dispositions produce vacillations in affective reactions which, in turn, are likely to create within-person variation in affective commitment to teams (WPVC_teams). We further propose that WPVC_teams enhances prediction and explanation of intraindividual fluctuations in work behavior and, interindividually, moderates the relationship between level of commitment and behavior.     

China's Banking Reform

This article discusses the main problems facing the Chinese banking system and concludes that, despite serious problems, the risk seems small that, in the near future, a financial crisis will occur that will pose severe problems for the international financial system. An internal financial crisis, however, could occur. Without government support, the economic viability of many of China's banks is questionable. The government and central bank authorities acknowledge the situation and have taken some steps toward reform. The most serious threat to the banking system lies in the accumulation of non-performing loans (NPLs)--many of them policybased loans extended by state-owned banks to money-losing state-owned companies with little expectation that they would be completely repaid. China has been taking measures to keep the problem from worsening and has created four asset management companies to dispose of NPLs that still have value. Since the Chinese economic reforms began in 1978, Chinese authorities have made significant progress in modernising their banking system, although they still have a long way to go. However, there are several ameliorating factors that still keep its financial and foreign exchange system viable. China's continued high rate of growth and high savings rate have funneled deposits into the banking system, while a $20-30 billion annual trade surplus together with an inflow of foreign direct investment at about $40 billion per year have resulted in an accumulation of foreign exchange reserves exceeding $200 billion. China does not carry an unusually heavy debt burden, either domestic or international, although its short-term borrowing in foreign currencies has been increasing. China does not currently face a serious risk of either a domestic or international liquidity crisis--unless, of course, a severe and prolonged world recession occurs that adversely affects Chinese exports as well as the inflow of foreign direct investment.
