TL;DR: In this article, the authors present a model which includes several starting points to enhance the efficiency of certification systems and the corresponding labels, such as reducing auditors' dependence, intensifying liability, increasing reputation effects, and minimizing audit costs.

TL;DR: The results show that although health is an important aspect for both functional food and organic food consumption, these two forms of consumption were influenced by different understandings of health: organicFood consumption is influenced by an overall holistic healthy lifestyle including a healthy diet and sport, while functional food consumption is characterized by small "adjustments" to lifestyle to enhance health and to increase psychological well-being.

TL;DR: A database analysis of the German certification system Quality and Safety (QS) and a workshop with the QS-certification bodies conducting 85% of all agricultural audits seek to deduce the first empirical hypotheses concerned with the connection between the reliability of third-party certification and the institutional framing of standards.

TL;DR: In this paper, the authors developed a comprehensive causal model to analyse data from 13,074 German consumers gathered through the representative German National Nutrition Survey II (Nationale Verzehrsstudie II).

TL;DR: In this paper, a review of marketing research for organic food consumption is presented, enabling the identification of research strengths and deficits, and the most investigated topics are cost to the consumer and consumer value and benefits.
