DEREGULATION AND THE VOLATILITY OF UK STOCK PRICES

This paper examines the behaviour of the UK stock market for significant changes in volatility over the four years surrounding Big Bang i.e. 27 October, 1986 when the market was substantially deregulated. The main findings are that after Big Bang but prior to Black Monday, the UK stock market was no more volatile than prior to Big Bang, but that after Black Monday, the UK market was more volatile than prior to Big Bang even after adjusting for increases in global volatility.     

Modeling and Forecasting the Sales of Technology Products

Managers in technology product markets require sales response models that provide substantive insights into the effects of marketing activities as well as reliable sales forecasts. Such markets are characterized by frequent introductions and withdrawals of multiple models by different companies. Thus, the data available on the performance of any individual model is scarce. A second characteristic is that the effects of product attributes and marketing activities could change over time as different types of consumers participate in the market at different points in time. Given sparse data, it becomes critical to specify a model that allows pooling of information across brand-models while at the same time providing brand-model specific parameters. We accomplish this via a hierarchical Bayesian model specification. Further, to capture the effects of changing consumer preferences over time, we specify a time varying parameter model. Our modeling framework therefore, integrates a hierarchical Bayesian model within a time varying parameter framework to develop a dynamic hierarchical Bayesian model. We employ data on digital cameras in the U.S. market to estimate the parameters of our proposed model. We use thirty-three months of national level data on the digital camera market with the data series beginning very close to the inception of this product category. We find that while there is little variation in reliance of benefits by early adopters, the second wave of adopters focus on Ease of Use followed by later adopters who rely on Storage and Image Quality. Looking at the elasticities of demand with respect to the various benefits, we find that at around the halfway point of our data series, the industry as a whole would have been better off investing in increasing image quality rather than storage if costs associated with the two are equal. However, at the end of the time horizon both benefits appear to have about equal impact. Further, the relative benefits of improving these attributes vary across brands and points in time. We then generate single period and multiple period ahead sales forecasts. We make different assumptions about information availability and find that the average (across brand-models and time) MAPE ranges from 7.5 to 14.5% for the model. We provide extensive comparisons of our model with 4 potential alternatives and find that our model outperforms these alternatives on the nature of substantive insights obtained as well as in forecasting out-of-sample especially when there is a very short time window of data.     

Managing Channel Profits: The Role of Managerial Incentives

The existing literature has examined how manufacturers can enhance profits by employing specific channel structures and channel coordination mechanisms. In this paper, we examine the implications of strategically designed managerial incentives for channel performance in a duopoly. We first analyze how equilibrium outcomes (especially manufacturer profits) are altered when the manufacturers provide their channel managers with strategically designed incentives. Following that, we examine how optimal channel structure decisions are altered when manufacturers provide their managers with strategic incentives, i.e., we examine how strategic incentives moderate optimal channel structure decisions. In contrast with the existing literature, we find that an asymmetric channel structure with one manufacturer employing a profit-maximizing retailer and the other integrated manufacturer providing strategic incentives for the channel manager in charge of pricing, is an equilibrium outcome under certain conditions. We then compare how the implications of strategic incentives differ from those of channel structure decisions and channel coordination initiatives, and discuss when and why strategic incentives yield superior outcomes from the manufacturer’s perspective. Our results shed light on the sparsely researched role of managerial incentives in the channel context.     

Canadian business perspective on nafta

This article presents some of the major criticisms concerning Mexico's entry into the NAFTA. Then it addresses these criticisms from the Canadian business executives’ point of view using data gathered from those currently doing business and not currently doing business in Mexico. The major concerns, costs, and benefits to Canadian firms have been identified. Candid comments from the business executives are contrasted with those views frequently portrayed in the popular press.     

A Comparative Analysis of the Use of Corporate Advertising in the United States and Japan

This article outlines one possible approach that companies can use to identify candidate countries for standardized international advertising campaigns. By clustering countries based on their similarity economically, culturally, and in their media availability and usage, marketers can identify those in which similar campaigns may be successful. In this paper, 40 countries were clustered into six groups within each of which standardization could be attempted. Discriminant analysis provided validation for the appropriateness of this six cluster solution. The implications of these results are discussed and directions for future research based on this approach are suggested.     

Understanding consumers’ social networking site usage

Abstract

The purpose of this research is to examine consumer motivations to use social networking sites (SNSs) for three distinct activities: (1) general SNS usage, (2) the joining of a business’s SNS page and (3) clicking on an advertisement on a SNS. To assist with this exploration we draw upon the decomposed theory of planned behaviour as a theoretical lens and conduct a mixed-method study that utilises both an empirical investigation as well as qualitative focus group interviews in order to delve deeper into specific reasons why individuals engage in SNS activities. Results show that a number of antecedents such as attitude, compatibility, relative advantage, complexity, normative influences and self-efficacy come into play when determining SNS usage activities. However, specific antecedents may vary according to the explicit activity under investigation. This study’s main contribution involves advancing our understanding of consumer behaviour as it relates to SNS activities by examining not only antecedents to intention but also attitude, subjective norms and behavioural control. Other contributions include additional development of the SNS literature, integrating SNSs into a classical theoretical framework and providing valuable insights and implications for both practitioners and researchers alike.     

Investigating the effects of a line extension or new brand introduction on market structure

Market structure has been characterized by the locations of brands in the perceptual space of households (perceptual map) and the importance weights associated with the attributes of this map. It is hypothesized that a line extension or a new brand introduced into this market could potentially affect the brand locations or the importance weights. We show how a simple extension of a recent approach to market structure analysis enables us to empirically identify which, if any, of these two aspects of market structure is affected by the line extension or new brand. An empirical application to the detergent product market is provided.

Balancing Profitability and Customer Welfare in a Supermarket Chain

We investigate the impact of price discrimination by a large Chicago supermarket chain. First we measure the impact of the chain's current zone-pricing policy on shelf prices, variable profits and consumer welfare across its stores. Using the chain's database to simulate a finer store-specific micro-pricing policy, we study the implications of this policy on profits and welfare. We show how a store-pricing policy that is constrained to offer consumers at least as much surplus as a uniform chain wide pricing policy still enables the retailer to generate substantial incremental profits.To ensure our pricing problem exhibits a well-defined optimum, we use the parsimonious, mixed-logit demand function that allows for flexible substitution patterns across brands and also retains a link to consumer theory. We discuss the issue of price endogeneity when estimating the demand parameters with weekly store-level data. Standard instrumental variables techniques used to account for such endogeneity also seem to increase the magnitudes of own-price elasticities thereby offsetting the problem encountered by previous researchers of predicted prices from a demand model exceeding those in the actual data.
