Critical Literature Review


1.1 Importance of Critical Literature Reviewing:

Critical literature review refers to assess the value of proposed area of research under different circumstances and contingencies rather than just describing it in the light of previous research. In order to undertake proposed area of research a critical literature review that explores the benefits and weaknesses of under discussion topic along with contingencies in which the construct behave differently especially in the case of management studies where numerous moderating variables affect the relationships is important. Though one can expect that academic authors do not lie or swindle their readers but still some hidden layers are found in academic writings Saunders et al., (2009). So to clear the picture about the construct, one should explore all these hidden layers as well. Moreover, critical literature review not only studies the evidences and logics behind the concept but also tried to find significance, viewpoints and interpretations to conclude in this respect Wallance & Wray (2006). This implies that in order to increase understanding about the topic one should explore both positive and negative aspects and where and on what grounds researchers are disagree to each other. In doing so, critical analyses of their empirical evidences along with methodology to interpret results, significance and how they tackle the limitations are important. This will allow finding the gap about that topic that is needed to explore in this context. In conclusion critical literature review is necessary to understand the proposed topic and to explore the gap that you can fill to add your contribution.

1.2 Balanced Critical Literature Review:

In the case of Sarah’s project, she put overemphasis on the benefits and limitations of complexity theory in her both attempts respectively. In her first attempt she presented complexity theory as effective organizational change strategy that can be used to prescribed practice. Additionally she did not provide significant empirical evidences to her review that arise the question in the mind of reader that on what ground prescribed practice of complexity theory can be assumed. She did not consider opposite arguments as limitations and contingencies to the implementation of complexity theory. On the other hand in her second attempt again she overemphasis to the weaknesses of complexity theory while assuming that complexity theory can not be use to prescribed practice due to its limitation. Her both attempts show one side of picture more prominently rather than describing both possibilities and limitations of complexity theory to prescribed practice.  Her tutor suggest her to adopt balance strategy and advise her neither to assume complexity theory as best prescribed practice nor to assume that it can not be used as prescribed practice exclusively. There are circumstances and contingencies to which complexity theory can be or can not be used as prescribed practice. Her tutor wants to consider both aspects along with empirical evidences rather than showing prejudice to one aspect only.

What Sarah needs to do?

In producing balanced critical literature review Sarah needs to adopt critical perspective to her readings. She can use to highlight the important statements and arguments in this respect. She should look precisely that this readings can help him or not and dialogue about the statement of author with herself to explore the issues. Try to summarize the reading into own words and compare how her understandings has been changed after this reading. On the other hand content selection of critical review is also important as it provides the background information about proposed topic in previous literature. However, critical balanced literature review does not follow or approve a concept but also include limitation of proposed area of research. While the approach should be balanced and include authenticity and weaknesses of construct under different contingencies rather than just approving or criticizing the proposed theory. So, Sarah should include the circumstances in which complexity theory is applicable and the factors that restrict it to be used as prescribed practice.

Saunders et al., (2009) has provided important check box to know hoe much critical is your literature review and its structure. In Sarah’s literature review, she relates her topic to previous researches but does not include both strengths and weaknesses at once. Her first attempt includes only strengths while in her second attempt only weaknesses were addressed. Literature review includes subjective opinions from different authors and converse about objective assessment of other’s work. Though her second draft was quite critical but overemphasis on weaknesses of complexity theory that the reader infers that complexity theory can not be used as prescribed practice. She did not include her own ideas about prescribed practice of complexity theory that also makes it difficult to address the gap within that study that needs to explore. For instance, without such objective opinion it is difficult to explore the circumstances in which complexity theory can be or can not be used as prescribed practice. On the other hand Sarah’s literature review mostly relies on one study of Burnes (2005) and do not narrow the concept of complexity theory from a broader view. Her literature review does not contain a clear title around which focus of study should make.

PREDICTORS OF EFFECTIVE CELEBRITY ENDORSEMENT 

2.1 Reason to select the topic:

Today firms are using famous celebrities and stars in order to endorse their products and services in view that popularity of that star can be used to attract customers to buy their products or services. Elberse (2007) suggests that in current scenario, advertisers are seeking the innovative ways to attract the targeted consumers while using celebrities is successful strategy in this respect. Shipmen (2000) reported that about 25% of US advertisements use celebrities to endorse their products or services. The idea came into my mind as result of discussion with my one friends from Pakistan after viewing the advertisement in which famous bollywood star Katherina Kaif endorse the bottled juice “SLICE” manufactured in Pakistan. Slice is successfully endorsed by Katherina and increase the sales volume of juice significant. Even most of the people especially from villages call it with Katherina’s bottle rather than its name Slice. On the other hand I also found myself using various cloth brands in response of advertisement in which my favorite celebrity wears that particular cloth. This implies that famous stars or celebrities can attract consumers to buy that product, if they are viewed using or advising to use that product. However, it is also viewed that different celebrities impact differently through endorsement to consumers’ buying behavior. This indicates that extent of effective celebrity endorsement is also contingent to the attributes o used celebrity that needs to explore further. So, all these statistics and inspiration from celebrities to buy that product or service stimulates me to explore the construct in respect of factors that can lead to successful celebrity endorsement.

2.2 Possible Research Question:

Following are possible research questions that would be tried to answer through current proposed study in this respect.

1.      Do using famous celebrities or stars to endorse products or services significantly affect consumers’ buying behavior?
2.      What are the attributes and factors of used celebrities that can lead to an effective celebrity endorsement?
3.      Do different types of celebrities (like athletes, entertainers or political personality) affect differently to the effectiveness of celebrity endorsement.
4.      Do different innovative media sources and advertisement technologies influence effectiveness of celebrity endorsement?

5.      Does the negative publicized information about that used celebrity affect the brand image negatively or not?

2.3 Key authors that can help to explore celebrity endorsement:

The concept of celebrity endorsement has gained the popularity among practitioners and advertisers are using celebrities endorsement significantly especially from last two decades. A number of researchers have studied celebrity endorsement with different perspective and methodologies. Silvera and Austad (2004) have studied the effectiveness of celebrity endorsement and also tried to explore the factors that can be used to predict the effectiveness of celebrity endorsement. In doing so, they use case studies about advertisements from Norway. The results from their proposed model show that attitude of viewers towards that endorser is strong predictor to the effective celebrity endorsement.

Similarly, Byrne, Whitehead and Breen (2003) have studied the case of J. Sainsbury who uses famous “James Oliver” to endorse their products successfully. It is useful study as it compares various celebrity endorsement strategies with that used by Sainsbury. They tried to explore the extent of recognition and association of consumers with James Oliver as celebrity endorser of Sainsbury.

More recently Minkove, Zhang and Trail (2011) also have tried to explore the effectiveness of celebrity endorsement in respect of types of celebrities and found that sportsmen are effective endorsers for both sports and non sports items. In doing so, they studied five characteristics including spots identification, athlete identification, celebrity fit, perceived value and intentions to purchase with respect to 42 items that are endorsed through sportsmen.

On the other hand White, Goddard and Wilbur (2009) have studied the limitations of celebrity endorsement and tried to answer that whether negative flow of information in media about used celebrity affects negatively to the image of endorsed brand in the minds of consumers or not. Their results confirm the notion that such negative flow of information about celebrities negatively transference the relationship of celebrity endorsement and brand image. Similarly a number of researchers have studied celebrity endorsement that can be use to enhance learning and to conduct research in the respect. Some of prominent studies are proposed by Biswas, Biswas and Das (2006), Choi and Rifon (2007), Erdogan, Baker and Tagg (2001), Louie and Kulik (2001) and Louie, Kulik, and Johnson (2001) etc.

2.4 Attributes of selected topic:

Raimond (1993) argued that attributes of research topic do not vary significantly but their extent of prominence. The most important part of a research project is to choose research topic as all subsequent parts are dependent on selected topic. In doing so, Saunders et al. (2009) have provided checkbox containing attributes of good research topic. They have divided these attributes into its capabilities that are related to its feasible to research and its worth to literature.

The selected topic originates from my interest towards an advertisement that stimulates me to research on it shows my fascination towards the selected topic. Precise extensive literature is available about celebrity endorsement that shows that the project can be done within time limit. Moreover, it also does not required high financial resources to conduct proposed research as questionnaire approach and focus group discussion from students are enough to conclude the results. So, the proposed research project is enough feasible to execute as it can be done under restricted resources and time and data can also be gather.

Other section of check box contains the attributes with respect to its appropriateness. Celebrity endorsement has become hot issue among researchers and firms pay huge amounts in order to endorse their products through famous faces that show a strong link of celebrity endorsement with theory and practice as well. They all are interested to know the important factors that cause to effective celebrity endorsement. Though selected topic does not address particular determinant of celebrity endorsement but still it excite to draw research questions and objectives about different predictors and factors of effective celebrity endorsement. Time has been changing and new determinants are needed to explore in the context of celebrity endorsement. For instance media sources and technology have been flourishing that provide opportunity to endorse products into different ways. So, current proposed topic has ability to produce fresh information to the literature. At last my interests in advertisement strategies completely match with the topic of celebrity endorsement that makes it worthwhile to conduct.
