Career

Goodhardt began his career working as a statistician for Attwood Panels, and later Aske Research with Andrew Ehrenberg. From 1981-95 he was Sir John E Cohen Professor of Consumer Studies at The City University Business School.

Apart from being the Chairman of the Board at the Ehrenberg-Bass Institute for Marketing Science, Gerald Goodhardt was Emeritus Professor, City University; Visiting Professor, Kingston University and also a Visiting Research Associate, South Bank University. Formerly Sir John E Cohen Professor of Consumer Studies, and Dean of the City University Business School, Gerald has spent 20 years in industry and commerce prior to 20 years as an academic. He has served as Chairman of the Market Research Society (Gold Medalist in 1969 and 1996) and as Honorary Secretary of the Royal Statistical Society. Gerald was also founding President of the Market Research Benevolent Association, published extensively in marketing and statistical journals, mainly in quantitative aspects of consumer behaviour and the audience's use of broadcast media.

Research

In the early 1980s, with Andrew Ehrenberg and Chris Chatfield, he extended the NBD model to account for brand choices. Finally published in 1984 the NBD-Dirichlet model of brand choice successfully modeled the repeated category and brand purchases within a wide variety of markets. [2] 'The Dirichlet', as it became known, accounts for a number of empirical generalisations, including double jeopardy, the duplication of purchase law, and natural monopoly. [3] It has been shown to hold over different product categories, countries, time, and for both subscription and repertoire repeat-purchase markets. [4] It has been described as one of the most famous empirical generalisations in marketing. Independently, Schmittlein, Bemmaor and Morrison published the same model in Marketing Science and showed a variety of its statistical properties, in particular when it reduces to the simple NBD model. [5] They labelled the univariate model as Beta Binomial/Negative Binomial Distribution. The model has since been extensively applied both by academics and marketing research consultancy firms.

<span class="mw-page-title-main">Consumer behaviour</span> Study of individuals, groups, or organisations and all the activities associated with consuming

Consumer behaviour is the study of individuals, groups, or organisations and all the activities associated with the purchase, use and disposal of goods and services. Consumer behaviour consists of how the consumer's emotions, attitudes, and preferences affect buying behaviour. Consumer behaviour emerged in the 1940–1950s as a distinct sub-discipline of marketing, but has become an interdisciplinary social science that blends elements from psychology, sociology, social anthropology, anthropology, ethnography, ethnology, marketing, and economics.

In marketing and consumer behaviour, brand loyalty describes a consumer's persistent positive feelings towards a familiar brand and their dedication to purchasing the brand's products and/or services repeatedly regardless of deficiencies, a competitor's actions, or changes in the market environment. It can also be demonstrated with other behaviors such as positive word-of-mouth advocacy. Corporate brand loyalty is where an individual buys products from the same manufacturer repeatedly and without wavering, rather than from other suppliers. Loyalty implies dedication and should not be confused with habit, its less-than-emotional engagement and commitment. Businesses whose financial and ethical values rest in large part on their brand loyalty are said to use the loyalty business model.

Neuromarketing is a commercial marketing communication field that applies neuropsychology to market research, studying consumers' sensorimotor, cognitive, and affective responses to marketing stimuli. The potential benefits to marketers include more efficient and effective marketing campaigns and strategies, fewer product and campaign failures, and ultimately the manipulation of the real needs and wants of people to suit the needs and wants of marketing interests.

Double jeopardy is an empirical law in marketing where, with few exceptions, the lower-market-share brands in a market have both far fewer buyers in a time period and also lower brand loyalty.

The following outline is provided as an overview of and topical guide to marketing:

Brand awareness is the extent to which customers are able to recall or recognize a brand under different conditions. Brand awareness is one of two dimensions from brand knowledge, an associative network memory model. It is a key consideration in consumer behavior, advertising management, and brand management. The consumer's ability to recognize or recall a brand is central to purchasing decision-making because purchasing cannot proceed unless a consumer is first aware of a product category and a brand within that category. Awareness does not necessarily mean that the consumer must be able to recall a specific brand name, but they must be able to recall enough distinguishing features for purchasing to proceed. Creating brand awareness is the main step in advertising a new product or bringing back the older brand in light.

The AIDA marketing model is a model within the class known as hierarchy of effects models or hierarchical models, all of which imply that consumers move through a series of steps or stages when they make purchase decisions. These models are linear, sequential models built on an assumption that consumers move through a series of cognitive (thinking) and affective (feeling) stages culminating in a behavioural stage.

The hedonic music consumption model was created by music researchers Kathleen Lacher and Richard Mizeski in 1994. Their goal was to use this model to examine the responses that listening to rock music creates, and to find if these responses influenced the listener's intention to later purchase the music. The article begins with a discussion of why the issue of music consumption is important. Music is then explored as an aesthetic product, prior to a discussion of what hedonic consumption is, as well as its origins, and concludes with an in-depth look at the model itself.
