Career

Professor 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, Professor 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 [2] the NBD-Dirichlet model of brand choice successfully modeled the repeated category and brand purchases within a wide variety of markets. '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, Bemmaor [5] [6] and Schmittlein, Bemmaor and Morrison [7] 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. They labelled the univariate model as Beta Binomial/Negative Binomial Distribution (NBD/BB in Bemmaor 1981 and BB/NBD in Schmittlein, Bemmaor and Morrison 1985). The model has since been extensively applied both by academics and marketing research consultancy firms.

Marketing is the process of exploring, creating, and delivering value to meet the needs of a target market in terms of goods and services; potentially including selection of a target audience; selection of certain attributes or themes to emphasize in advertising; operation of advertising campaigns; attendance at trade shows and public events; design of products and packaging attractive to buyers; defining the terms of sale, such as price, discounts, warranty, and return policy; product placement in media or with people believed to influence the buying habits of others; agreements with retailers, wholesale distributors, or resellers; and attempts to create awareness of, loyalty to, and positive feelings about a brand. Marketing is typically done by the seller, typically a retailer or manufacturer. Sometimes tasks are contracted to a dedicated marketing firm or advertising agency. More rarely, a trade association or government agency advertises on behalf of an entire industry or locality, often a specific type of food, food from a specific area, or a city or region as a tourism destination.

Marketing research is the systematic gathering, recording, and analysis of qualitative and quantitative data about issues relating to marketing products and services. The goal is to identify and assess how changing elements of the marketing mix impacts customer behavior.

In marketing, market segmentation is the process of dividing a broad consumer or business market, normally consisting of existing and potential customers, into sub-groups of consumers based on shared characteristics.

Market research is an organized effort to gather information about target markets and customers: know about them, starting with who they are. It is an important component of business strategy and a major factor in maintaining competitiveness. Market research helps to identify and analyze the needs of the market, the market size and the competition. Its techniques encompass both qualitative techniques such as focus groups, in-depth interviews, and ethnography, as well as quantitative techniques such as customer surveys, and analysis of secondary data.

Consumer behavior is the study of individuals, groups, or organizations 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.

<span class="mw-page-title-main">Advertising management</span> Part of the advertising industry

Advertising management is a planned managerial process designed to oversee and control the various advertising activities involved in a program to communicate with a firm's target market and which is ultimately designed to influence the consumer's purchase decisions. Advertising is just one element in a company's promotional mix and as such, must be integrated with the overall marketing communications program. Advertising is, however, the most expensive of all the promotional elements and therefore must be managed with care and accountability. Advertising management process also helps in defining the outline of the media campaign and in deciding which type of advertising would be used before the launch of a product.

<span class="mw-page-title-main">Brand loyalty</span> Marketing term for a consumers emotional attachment to a given brand

In marketing, brand loyalty describes a consumer's positive feelings towards a 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 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.

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. Brand awareness 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. 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.

In probability and statistics, the Gompertz distribution is a continuous probability distribution, named after Benjamin Gompertz. The Gompertz distribution is often applied to describe the distribution of adult lifespans by demographers and actuaries. Related fields of science such as biology and gerontology also considered the Gompertz distribution for the analysis of survival. More recently, computer scientists have also started to model the failure rates of computer code by the Gompertz distribution. In Marketing Science, it has been used as an individual-level simulation for customer lifetime value modeling. In network theory, particularly the Erdős–Rényi model, the walk length of a random self-avoiding walk (SAW) is distributed according to the Gompertz distribution.
