The Effects of Advertising Media on Sales of Insurance Products: a Developing-Country Case

The effects of advertising media on sales of insurance products: a developing-country case S. A. Aduloju Department of Insurance and Actuarial Science, University of Lagos, Lagos, Nigeria A. O. Odugbesan Formerly of Department of Business Administration, University of Lagos, Lagos, Nigeria, and S. A. Oke Department of Mechanical Engineering, University of Lagos, Lagos, Nigeria Abstract Purpose – Characterized by declining goodwill and exemplified sharp drop in gross premium, the Nigerian insurance industry, in recent times, has experienced turbulent economic challenges that necessitated re-engineering of its core activities.However, advertising and sales are core activities, which are important predictors of stability and growth in the insurance industry. Consequently, the purpose of this paper is to examine the impact of advertising on sales of insurance products. Design/methodology/approach – An empirical investigation is carried out using a survey that utilizes quest ionnaires, interviews, and field observation as major research instruments. A total of 71 insurance companies in Nigeria, which represent the total operating insurance companies in Nigeria at the time of study, were surveyed.With 100 scientifically selected subjects sampled, descriptive analysis was employed to understand the relationship and the strength of such relationships. Findings – It was found that advertising had effects on sales volume and improved public image. However, the choice of advertising medium, the message, and the format are critical ingredients of a successful advertising program in the insurance industry. Research limitations/implications – The insurance industry in Nigeria was studied from a holistic viewpoint due to the need to present reliable and detailed information for decision makers.However, limitation in achieving this relates to the reluctance of respondents to release information for the study. Practical implications – The impli cation of this research is that proper control of advertisement budget vis-a` -vis the expected sales volume could be made. Thus, organizations could spend budgets more effectively on growth enhancing projects instead of excessive wastage of funds on advertisement. Originality/value – This paper seems to be the first original work that concerns the impact of advertising on sales in the Nigerian insurance industry.As such, it bridges a gap that is opened for investigations. It may be of great value to decision making seeking for control tools. Keywords Insurance, Nigeria, Advertising media, Sales management Paper type Research paper 1. Introduction Over the years, there has been tremendous decline in the goodwill of the Nigerian insurance industry as a result of poor performance in the payment of insurance claims. The sharp drop in gross premium exemplifies this problem. Randle (2003) estimated a decline of more than 89. 4 percent in the 1999/2000 comparative periods.This decl ine may have worsened as a result of the global economic crisis. There is therefore the need to advertise insurance products in order to increase sales. Unfortunately, no reliable records exist on the impact of advertising on sales of insurance products, thus suggesting its strong need. The need to examine the impacts of advertising on sales volume is further strengthened by the significant value of the total premiums generated in Africa, which originated in South Africa (84 percent) while only an insignificant value (16 percent) is partly contributed by Nigeria.Thus, with the enormous advertising expenditures, it becomes necessary to know if such expenditures justify sales volume obtainable from the advertisement efforts. Luo and Donthu (2005) identified advertising media and spending inefficiencies in generating sales, and concluded that top 100 marketers’ advertising spending in print, broadcast, and outdoor media are not efficient and could bring in 20 percent more sales. Sadly, the case relating to insurance products was not treated. Also, there is a strong need for understanding the impacts of advertising on sales volume.Furthermore, although empirical evidence in major markets of the world shares a significant relationship between advertisement and sales volume, there is no reliable data and information on the subject in developing countries such as Nigeria. The absence of this information provides a wide gap and poor understanding on the effectiveness of advertisement on sales. The purpose of the study is to investigate the impact of advertising on the sales of insurance products. Advertising ranks among the major tools of promotion in general and awareness in particular.The study investigates if there are good advertising opportunities insurance industry can make use of, and examine the various advertising media commonly used by the insurers with particular reference to Nigeria. How would the customers know that a particular product will satisf y some needs unless such is communicated to them? As a pivot of economic development, insurance certainly has a major role to play. The issue now is that the sector performance is far below expectation. An important question is why?Is there any inherent difficulty in growing and promoting this business in developing world? Very many factors have been put forward for this performance, and it should be mentioned that it is not the intention of this study to discuss them. It is important, however, to find out the effectiveness of the choice of advertising media on the sales volume of insurance organizations. A study of this nature may prove to be of immense benefit to industry managers on how to make positive impression about their business and product given the dynamic nature of our socio economic environment.Past studies reveal a fairly strong relationship between advertising investments and sales. Twedt and Knitter (1964) observed some relationships between larger investments in pri nt media and profits. Sturgess and Young (1981) identified the direct relationship between sales and advertising expenditures as more relevant to a company’s performance variables than any other test of communication effectiveness of advertising. Perreault and McCarthy (2000) admit that one of the methods of measuring advertising effects is to evaluate sales.Schultz and Wittink (1976) revealed that although some studies have reported a positive influence of primary advertising on primary demand, no conclusive empirical evidence has been brought to bear on the major premise. It is therefore the goal of the current work to bridge this important gap. The effects of advertising media JRF 10,3 The paper is sectioned into the following: introduction, methodology, data analysis, and conclusion. The introduction provides an insight into the significance of the problem and the need to bridge the knowledge gap.Section 2 presents the methodology, which provides the framework for the pre sented study. In Section 3, data analysis is presented based on the results of the survey instruments. Section 4, the final section, provides concluding remarks. 2. Methodology The aim of this research is to carry out an empirical investigation of the extent to which advertising affects sales. This is a survey research whose objectives are to find answers to the following research questions, and test the relevant hypotheses. This section presents the methodological approach adopted to gather relevant data necessary for this study. . 1 Study population, sampling design, and research instrument The Nigerian Insurance Digest, 2006 indicates that there were 96 insurance companies operating in Nigeria as at December 31, 2006. No available records confirm that new companies have been formed since, except for the issues of mergers and acquisitions that characterized the recapitalization/consolidation exercise. A total of 71 companies have since emerged from this exercise. The study populat ion embraced all the staff engaging in marketing, public relations, and advertising in these 71 insurance companies.Most of these companies are direct insurers since they deal directly with the members of the public. Reinsurance companies, though, also engage in advertising activities, were excluded from this study because their impact or contact with the members of the public is indirect. Since it would not be feasible to contact all the staff that represents the population for the study, sampling method was used, and the study was limited to Lagos state, the commercial center of Nigeria. A sample of 100 subjects selected from some insurance companies in Lagos was used.The sampling method was used to avoid bias in the selection procedure, and to achieve maximum precision for a given outlay of resources. Essentially, two research instruments were used: questionnaire and interview. For the questionnaire, 100 copies were distributed to respondents selected from various insurance compa nies in Lagos, Nigeria. In order to ensure high response ratio, the questionnaires were administered personally. To achieve this a number of contacts have been made to the management of those companies soliciting for their cooperation.Also, diligent care was exercised to avoid ambiguity in drafting the questionnaire. Personal interview was conducted with selected executives in the insurance companies (Dillion et al. , 1994). The face-to-face contact with respondents assisted in obtaining high quality data since more information is communicated between human beings communicating directly with each other than using other means. 2. 2 Method of data analysis The research proposed to use such descriptive statistics as simple percentages to compute the data obtained.For hypothesis testing, coefficient of correlation would be employed. Lucey (2002) highlights the benefits of using correlation coefficient when trying to analyze independent and dependent variables in order to understand the relationship between them. The correlation coefficient reveals the strength of such The effects of relationships. advertising media 2. 3 Restatement of research questions The research questions are as follows: RQ1. Is a company’s failure to use advertising a result of lack of good advertising opportunities?RQ2. Do the results of other promotional tools affect the use of advertising? RQ3. Is the use of advertising dependent on the measurability of its results? RQ4. Is there any relationship between advertising expenditure and sales figure? 2. 4 Research hypotheses The hypotheses stated will be used to test the relationship between sales figures and advertising figures (Asika, 2006). The statistical procedure is to state the null hypothesis (H0), which is to be followed by the alternative hypothesis (H1).While a H0 is a statement that no change has occurred from the condition specified, the H1 is a reversal of a H0. Thus, if in hypothesis testing, a H0 is rejected, then, the H1 will be accepted: H0. There is no relationship between advertising expenditure and sales figure. H1. There is a relationship between advertising expenditure and sales figure. 2. 5 Research design The research uses explorative research design in order to gain insights into the subject studied. The research design is that of descriptive survey.It is meant to assess the importance attached to advertisement by insurance organizations. Specifically, the research design would reveal availability of good advertising opportunities for insurance firms, factors affecting a firm’s decision to use advertising, relationship between advertising and company’s performance in terms of sales volume, and justification of advertising expenditure, using profit as the bottom line. 3. Data analysis In Section 2, it was mentioned that empirical investigation would be carried out on the extent to which the choice of advertising medium affects sales.The summaries of the results of the survey q uestions, and how these answer the stated research questions are presented in this Section 3. In fact, we will like to find out whether a company’s failure to use advertising is a result of lack of advertising opportunities, whether the use of advertising is dependent on the measurability of its results, and whether there is any relationship between advertising expenditure and sales figure. These results also attempt to seek support for the hypothesis stated. 3. 1 Response rate and respondents’ characteristicsA total of 100 copies of the questionnaire were distributed to respondents. The challenges of recapitalization in the insurance industry, and subsequent rearrangements including the necessary formalities made the task of getting JRF 10,3 audience difficult. A total of 84 questionnaires were collected out of which two were found unusable for the purpose of analysis. The response rate of 48 percent was thus achieved. The results were analyzed with the use of the fol lowing statistical procedures: (1) the frequency distribution of some parameters; (2) the percentages of the parameters studied; and 3) bar charts were also used for further illustration of some of the results obtained. The first five questions of the questionnaire deal with the characteristics of the respondents, specifically their bio data. These are presented in Table I. Out of the 82 respondents analyzed, 50 are males while 32 are females. The sample members were conveniently selected at random, rather than based on quota. Since 61 percent of the respondents are males and 39 percent are females, should one conclude that 61 percent of the workforce in the insurance industry is male and 39 percent female?This is an interesting possibility due to the fact that a good number of females prefer to be self-employed in order to care for their home responsibilities. From Table II, majority of the respondents are 40 years and below, an overwhelming 89 percent (i. e. 44 percent for below 3 0 years, and 45 percent for age bracket 31-40). About 11 percent of the respondents are above the age 41, while none of the respondents is over 60 years. This analysis suggests that productive and dynamic personnel marketing and public relations functions of these insurance companies.The analysis shows 43 single and 39 married persons indicating 52 and 48 percent respondents, respectively (Table III). This is a fair distribution. From Table IV, 46 of the 82 respondents possess higher national diploma and degrees, 14 respondents possess higher degrees in form of MSc/MBA, and 16 respondents possess professional qualifications.

Marital status of respondents Single Married Total 43 39 82 52 48 100 The fact that only six respondents (a mere 8 percent) possess national diploma and below shows that marketing and public relations job in the insurance industry is taken over by professionally and academically qualified personnel. From Table V, 71 respondents (which is 87 percent) have not more than ten years working experience, while those having more than 16 years working experience constitute only 4 percent. None of the respondents however, have worked more than 25 years. 3. Descriptive statistics of the sample responses In presenting the data obtained in response to section B of the questionnaire, we will use tables of percentages as well as bar charts. A cumulative of 91 percent agree that insurance is necessary for socio-economic development while a mere 4 percent disagree (Table VI). One may conclude that majority of the respondents believe that insurance has a vital role to play in an economy. Here, again, Table VII shows that 91 percent agree that the Nigerian public is apathe tic toward insurance purchase, while a mere 5 percent could not agree. A total of 69 respondents (20 ? 9) agree that the level of insurance sales in the country is not encouraging, which is 84 percent of the respondents (Table VIII). On the other hand, 10 percent of the respondents disagree. This naturally confirms the response presented in Table VII indicating that the Nigerian public is apathetic toward insurance purchase.

The interesting thing is that 24 percent could not state whether or not the insurance industry performance depends on the performance of the other sectors.Here, respondents were allowed to choose more than one factor they considered as responsible for the low sales of insurance products. In order of frequency, low level of awareness, poor industry image, high level of illiteracy, and low per capital income top the list with 73, 57, 45, and 45 percent, respectively (Table X). These factors are represented on the bar chart (Figure 1).

One may assert that while marketing principles are universal, their application to categories of products varies. All the respondents confirm that their companies have marketing or public relations department (Table XII). This shows that the issue of marketing or public relations is given adequate attention with staff assigned specific responsibilities.An overwhelming 93 percent of the respondents agree that their companies engage in one form of advertising or the other (Table XIII). It shows that companies could no longer be content with the provision of goods and services alone, they also see the need to inform the general public of their existence and the benefits they offer to the society. From Table XIII already discussed above, six respondents confirm that their companies do not engage in any form of advertising. In response question 9 on the questionnaire asking for the reasons, they pointed to the factors shown in Table XIV.Out of the six respondents, three chose â€Å"preference for other promotional tools,† four chose â€Å"high cost of advertising,† and two chose â€Å"difficulty in measuring advertising Low income Low awareness Illiteracy Religion Response Number Percentage Yes No Total 55 27 82 67 33 100 The effects of advertising media Figure 1.

This means there may be good advertising opportunities, but measuring the effect of advertising on sales is a problem. In response to the question on advertising objectives, 72 percent of the respondents chose â€Å"inform the public about the company,† 55 percent chose â€Å"increase sales,† and 52 percent chose †Å"improve company’s image† among the major objectives of advertising (Table XV).From the above analysis, increase in sales is the leading advertising objective, apart from giving information about the company. Ranking in frequency, newspapers, radio, and magazines are the most favored advertising media with 79, 59, and 49 percent, respectively (Table XVI). These and other media used are presented on the bar chart (Figure 2). The analysis above indicates that 51 percent of the respondents reveal that developing advertising activities is a joint responsibility of the company’s staff and the advertising agencies (Table XVII).About 41 percent of the respondents show that it is entirely the work of advertising agencies while only 8 percent state that it is an internal responsibility. The report shows that insurance companies in developing their advertising program actively seek for the inputs of the advertising agencies. While only 5 percent of the respondents could n ot decide, a cumulative of 83 percent agree that the success of advertising activities depends on the integration of all marketing promotional tools. While no respondents strongly disagree, 12 percent disagree (Table XVIII).The 83 percent in agreement point to the fact that there is the need for integration of all marketing communications in order to achieve good result.

Whether advertising success is dependent on the integration of all marketing promotional tools From Table XIX, an overwhelming majority of the respondents agree that the choice of advertising medium is critical to the success of advertising activities. This is indicated by the sum of 20 percent for â€Å"strongly agree† and 70 percent for â€Å"agree† respondents making 90 percent. While 6 percent could not decide, a mere 4 percent disagree. Insurers therefore will have to pay attention to the medium selection if their advertising objectives are to be met.In Table XX, the respondents neither â€Å"disagree† nor â€Å"strongly disagree† with the notion that the choice of message can make a difference between success and failure of any advertising activity. While only 1 percent of the respondents could not decide, 99 percent agree with the notion that the choice of message is critical to any successful advertising program. Again, insurers need to pay attention to the message in endeavoring to reach the public. JRF 10,3 About 96 percent of the respondents support the notion that advertising has made positive impact on their company performance (Table XXI).This needs no further elaboration. Owing to the importance of this issue, question 16 in section B was reframed again as question 17 with the aim of testing the genuineness of the respondents’ answer. Interestingly, as in Table XXI (which analyzed responses to question 16), 96 percent of the respondents affirm that advertising has had posi tive effects on their company’s performance (Table XXII). Specifically, 73 percent of the respondents agree that advertising leads to increased sales, the figure which is marginally exceeded by 74 percent for â€Å"favorable public image† (Table XXIII).Also 61 percent of the respondents agree that advertising leads to increased number of prospects. This is presented in the bar chart shown in Figure 3. None of the respondents picked â€Å"no† for the answer, although it was included in the three options (Table XXIV). While 76 percent of the respondents believe that advertising expenditure is justified based on the results achieved, 24 percent could Response Number Percentage Table XIX.

One may align with the fact that advertising expenditure, if properly done, is not a wasteful resource, after all.The fact that only 27 percent agree, and 37 percent could not decide in support of the notion shows that advertising agents have a long way to go in measuring up to international standard (Table XXV). About 36 percent (30 ? 6 percent) disagree that advertising professionals are performing at world standard.

Analysis of research questions In Section 3, the research questions proposed in Section 1 were restated. These research questions, four in number, are analyzed as follows based on the information received from the respondents: RQ1. Is a company’s failure to use advertising a result of lack of good advertising opportunities? To answer this question, Table XIV (already analyzed somewhere above) is hereby represented in Table XXVI. In response to question 8 on the questionnaire, six out of the 82 respondents confirmed that their companies do no advertising at all.Question 9 asked for the reasons and four options were listed as follows: (1) company’s preference for other promotional tools; (2) high cost of advertising; (3) lack of good advertising opportunities; and (4) difficulty in measuring advertising effects. From Table XXVI, none of the respondents chose option (3), i. e. â€Å"lack of good advertising opportunities† as the reason for not advertising. One can therefore conclude that there are a number of advertising opportunities in the country for companies who care to advertise: RQ2. Do the results of other promotional tools affect the use of advertising?Again, this question would be answered using the response analysis presented in Table XIV. Out of the six respondents whose companies do no advertising, three stated that it was because their companies preferred the use of other promotional tools. When compared with the sample size, which is 82, the position of the three respondents is too insignificant to infer a generalization. One could thus conclude that the results of other promotional tools do not negatively affect the use of advertising: RQ3. Is the use of advertising dependent on the measurability of its result?Using Table XXVI, out of the six respondents who confirm that their companies do not advertise, two chose â€Å"difficulty in measuring advertising effects† as the reason. Again, this position of the two respondents is too insignificant when compared with that of the entire sample size of 82: RQ4. Is there any relationship between advertising expenditure and sales figure? In answering this question, the response to question 17 in the questionnaire will be used. The response as analyzed using Table XXIII (already analyzed somewhere above) is hereby represented in Table XXVII.Response Number Percentage Table XX VI. (Repeated) Reasons why Preference for other promotional tools 3 50 some companies do not High cost of advertising 4 67 advertise? Difficulty in measuring advertising effect 2 33 From this table, advertising has a number of positive effects on the organization. Among others, 74 percent of the respondents believe it has improved public image, 73 percent believe it has increased sales volume and 61 percent believe it has increased the number of prospect visits. All these show a positive relationship between advertising and sales. 3. 4 Test of hypothesisThe hypothesis to be tested is termed the H0 – a statement that no change has occurred from the position specified for a hypothesis. If however we reject the H0, the H1 will be accepted. An H1 is a statement, which is a reversal of a H0. 3. 4. 1 Restatement of the hypothesis. H0. There is no relationship between advertising expenditure and sales figure. H1. There is a relationship between advertising expenditure and sales figu re. In order to test for this hypothesis, data obtained from some insurance companies in respect of their sales figures (gross premium incomes) and their advertising expenditures for a five-year period was used. . 4. 2 Five-year figures of premium and advertising. These are shown in Table XXVIII. Our main objective is to test whether or not there is a relationship between advertising expenditure and sales volume. The statistical tool used here is Pearson’s product moment coefficient of correlation denoted by r. This coefficient gives an indication of the strength of the linear relationship between two variables. In our case, the two variables are: (1) Advertising expenditure, which is the independent variable represented by x. (2)Sales figures (gross premium income) which is the dependent variable denoted by y.

Lucey states further that a strong correlation between two variables would produce an r value in excess of ? 0. 9 or 20. 9. If the value were less than, say 0. 5 there would only be a very weak relationship between the variables. The value of our computed coefficient of correlation (r) is 0. 99.This indicates a very strong positive correlation between the two variables, i. e. advertising expenditure and sales figure denoted by x and y, respectively. The decision is that we reject the H0, which states that there is no relationship between advertising expenditure and sales figure, and accept the H1, which states that there is a relationship between advertising expenditure and sales figure. 4. Conclusions This study investigates how advertising could be used by the insurers to disseminate information on the vital role they play. The study concludes that: .The image problem and the poor sales of insurance products are not necessarily the result of the bad economy but the failure to engage in marketing communications. . Emphasizing other roles of insurance as financial intermediation and supplement to government’s efforts in providing social security will make it more attractive. . Greater benefits accrue when advertising is fully integrated into the whole mass of marketing communications. . There are good opportunities for the insurers to advertise their products, advertising practitioners have not measured up to international standards. .For good advertising output, the message and format are the joint responsibility of the insurance staff and advertising agencies. . The major advertising media used by the insurers are the newspapers and the radio. The use of the internet in Nigeria should be given due attention. . The choice of advertising medium is a critical success factor in any a dvertising activity. . The major effects of advertising on companies were found to include sales volume and improved public image. A number of obstacles militate against attainment of growth in the insurance subsector, notably, hostile economic environment.Relentless advertising campaign can take a company to the next level of growth. The research has also shown that advertising expenditure is justified going by the positive effects such expenditure has on a company’s performance. Furthermore, the message and the format have also been found to be critical ingredients of a successful advertising program. It is recommended that: . The insurance executives should realize that their activities do not end with producing good services. Passing information to the public about their services and benefits thereof must be vigorously pursued through advertising. For sustainable competitive advantage there is a need for integration of all marketing communications, as this will reduce con flicts in organizations. . A careful blend of print and electronic media is very essential in order to properly serve each market segment. . Sales persons are the ones on ground since they are always in the field. Their inputs must always be sought while designing advertising message and format. . The lack of records regarding advertising budget and actual expenses is a problem in many insurance organizations.There is a need to keep adequate records of advertising expenditure, as this is necessary for proper evaluation. . The practitioners must promote other important roles of insurance such as savings, financial intermediation and provision of social security. . In the area of image laundry there can still be mutually beneficial cooperation in the midst of competition among the insurers. . In this regard, the insurance industry as a whole should embark on an industry’s advertising in order to promote subjects of common interest.This will also reduce the overall cost of adver tising. In this work, a convenience sampling method is used. While the size of the sample is fairly large (100), a major limitation is that the sample is taken in Lagos: one state out of 36. The fact that some major towns in the country (i. e. Abuja, Port Harcourt, Kano, and Ibadan) were left out could limit the degree of representativeness of the sample. However, the fact that Lagos is home to almost 90 percent of the headquarters of insurance companies in Nigeria makes the findings of this study representative of the population.Consequently, these findings would form a platform on which companies can base some of their marketing decisions. Future research could focus on the effects of publicity and public relations on sales, and on the better methods of separating advertising effects from the total marketing effects.
