Research Objectives and Key Topics

This thesis investigates how the number of certification seals and the level of pretentiousness in product benefit claims affect consumers' purchase intention and willingness to pay for food products. The core research question explores whether an optimal number of seals exists that maximizes these consumer intentions, while also examining the mediating roles of perceived product quality and manufacturer conscientiousness.

• Impact of multiple certification seals on consumer perception
• Influence of product benefit claim pretentiousness
• Interaction effects between certification seals and benefit claims
• Mediating role of perceived product quality
• Mediating role of manufacturer conscientiousness perception

Excerpt from the Book

Summary of Chapters

1. Introduction: This chapter introduces the research context, specifying the key dilemma faced by brand managers regarding certification strategies, and defines the primary research objective and questions.

2. Theoretical background: This chapter reviews existing literature on certification as a signal and establishes the theoretical framework, developing hypotheses regarding the impact of multiple seals and benefit claims on consumer behavior.

3. Methodology: This chapter describes the research design, including a pre-test to determine optimal stimuli and the setup of the survey-based framed field experiment for the main study.

4. Research results: This chapter presents the empirical findings, covering data preparation, statistical analysis, and the evaluation of the conceptual model based on the collected survey data.

5. General discussion and conclusion: This final chapter interprets the research findings, relates them to existing literature, discusses academic and managerial implications, and identifies research limitations and future study recommendations.

Frequently Asked Questions

What is the core focus of this thesis?

The thesis investigates the effectiveness of product certification seals as a marketing tool, specifically examining how the number of seals and accompanying benefit claims influence consumers' purchase intentions and their willingness to pay for food products.

What are the primary themes addressed?

The research centers on consumer signaling theory, the impact of multiple quality signals, the role of perceived product quality, and the influence of manufacturer conscientiousness on consumer decision-making.

What is the central research question?

The main question is: Is there an optimal number of certification seals on the packaging of an unknown food product that maximizes consumers' purchase intention and willingness to pay?

Which methodology was employed for this research?

The author conducted a survey-based framed field experiment in a real-world retail environment (a supermarket in Augsburg, Germany), using a factorial design (number of seals x claim pretentiousness) to test the hypotheses.

What aspects does the main body cover?

The main body reviews the theoretical background, details the experimental methodology (including a pre-test), presents the statistical analysis of the experiment results, and discusses the implications of these findings.

Which keywords define this work?

Key terms include certification seals, benefit claims, purchase intention, willingness to pay, product quality perception, manufacturer conscientiousness, and signaling theory.

How did the researcher ensure the results were not biased by existing brand knowledge?

The experiment used a fictitious brand, "JamJam," which was pre-tested to ensure that consumers were unfamiliar with it and that the label did not inadvertently evoke strong preconceived associations.

How does this thesis contribute to managerial practice?

The results advise marketing managers that a "multi-seal" strategy is not necessarily an effective way to boost sales, as consumers often struggle to process multiple seals or do not assign them significant value, suggesting that focusing on the product and label quality might be more beneficial.
