This dissertation study attempts to understand excessive buying, a phenomenon of both theoretical and practical interest. I define excessive buying as "an individual type of buying behavior whereby consumers repetitively spend more than they should based on financial considerations". I develop a conceptual typology of excessive buying, building on the time-inconsistent preferences and automaticity theory. The new typology categorizes five specific types of excessive buying behavior: 1) habitual, 2) possessive, 3) remedial, 4) rewarding, and 5) out-of-control. Based on past literature and the typology, I generate scale items to capture the conceptual and logical variance in excessive buying. Psychometric properties of the scale are tested via Confirmatory Factor Analysis using a student and random adult sample. Nomological validity of the scale is confirmed by testing hypotheses formulated based on hedonic shopping values and the self-defeating behavior theory. The empirical analyses suggest that excessive buying results from stress, using shopping as an escape from reality, and little consideration for the potential outcomes of one's current behavior. Excessive buying leas to both financial problems and negative emotions.

This dissertation is an empirical study of demand and supply in differentiated products markets using supermarket scanner data on two particular product categories - canned tuna and hot-breakfast cereals. First, I study the impact of retailers' price promotions on consumer demand and retailer profits in the canned-tuna product category. Since canned tuna is storable, I examine whether consumers stock up during sales. The results suggest that only a limited amount of stockpiling exists in this product category. Since inventory is not very important, consumer demand is thus modeled by a static demand model with a random-coefficients-nested-logit specification, which is estimated by the Markov Chain Monte Carlo method. The unit-sales decomposition results show that on average 36% of the demand response to price promotions comes from brand-switching, so market expansion effects due to consumers switching from the outside good and to higher quantities usually dominate the brand-switching effect. Using the demand estimates, I compute optimal retail prices assuming that stores are local monopolists and choose prices to maximize static category-level profits. I find that regular prices at "high-low" stores are typically at or slightly below the optimal prices, but that regular prices at "every-day-low-price" stores are substantially below the optimal prices. These results suggest that retail price levels and price promotions are more likely related to local market conditions such as retail competition. In addition, I study the effects of store-brand (SB) entry on the demand elasticities of incumbent national brands (NB), consumers' substitution patterns for national and store brands, and the implications for consumer welfare in the hot-breakfast-cereals product category. A random-coefficients model of consumer demand is estimated by the generalized-method-of-moments approach. The empirical findings are: (1) After the entry of SB's, demand becomes more elastic for non-imitated NB's, and either more elastic or shows no change for imitated NB's; (2) in general, substitution patterns for NB's and SB's are asymmetric, i.e., when the prices of their favorite products increase, most NB buyers tend to substitute to other NB products, but SB buyers will substitute to the corresponding imitated NB's; (3) the increase in consumer surplus due to SB entry is trivial for an individual consumer, but the aggregate benefit could be quite substantial.

This study is focused on identifying cultural typologies of the Indian population group. These typologies or dimensions are analysed from a consumer behaviour perspective with strong implications for marketers who need to take cognisance of these typologies when developing new product offerings and devising marketing campaigns targeted at this population group. The consumption behaviour of Indians are compared and contrasted with the other predominant race groups in South Africa (namely Whites, Blacks and Coloureds), in terms of expenditure and buying power. Further, an analysis of Indian culture typologies provides marketers with insight into cultural issues that have a bearing on the development of marketing strategies. The findings that have emerged from this study are important for various reasons. Over 75% of the total Indian population live in KwaZulu-Natal (Census 1996). Further, compared to other race groups, the Indian population has a high rate of urbanisation with 96.8% of the population living in metropolitan areas (ibid.). Education levels supercedes those of the Black and Coloured population groups with 30.4% of Indians having completed matric and l0.4% having furthered their education (South Africa in Transition: StatsSA). In keeping with this trend, in comparison with the other race groups, Indians have a high penetration of English spoken as a first language (93.2%). While 21% of the Indian population are characterised as middle to upper income earners, occupying LSM's 6 to 10, Indian households in the Durban Metropolitan area have more earners (33.2%) per household in comparison to the Black and White population groups (Stats South Africa). In addition, an increasing number of Indian women are entering the workforce and are becoming more active in decision-making. Findings related to Indian culture have unearthed that while Indian culture has imbibed a global culture as far as dress, entertainment and lifestyle are concerned, traditional beliefs and values, including that of religion, are steadfastly held onto. However, this dissertation also finds that the Indian population group is highly materialistic and great attention is focussed on the accumulation of possessions. Further, materialism within the Indian population, is seen as a reflection of status. / Thesis (MBA)-University of Natal, Durban, 2002.

Using a simple linear regression model for estimation could give misleading results about the relationship between Yt, and Xt, . Possible problems involve (1) feedback from the output series to the inputs, (2) omitted time-lagged input terms, (3) an auto correlated disturbance series and, (4) common autocorrelation patterns shared by Y and X that can produce spurious correlations. The primary aim of this study was therefore to use the Box-Jenkins Transfer Function analysis to fit a model that related petroleum consumption to disposable income> The final Transfer Function Model z1t=)C(1-w1 B)/((1-δ1 B) B^5 Z(t^((x) +(1-θ1 B)at significantly described the data. Forecasts generated from this model show that petroleum consumption will hit a record of up to 4.8636 in 2014 if disposable income is augmented. There is 95% confidence that the forecasted value of petroleum consumption will lie between 4.5276 and 5.1997 in 2014. / Thesis (M. Com. (Statistics) North-West University, Mafikeng Campus, 2005
