Will more regulations achieve better consumer protection?

Are more regulations in the food and agriculture industry a guarantee for improved consumer protection or are "market solutions" the better approach? For Dr. Martin Wille, permanent secretary at the Federal Ministry for Consumer Protection, Nutrition and Agriculture, "there is no question that government action is required in the interest of consumer protection". Prof. Gerhard Scherharn, University of Hohenheim, and Prof. Stefan Tangermann, University of Göttingen, make the case for "better" regulations and controls, whereas Prof. Roland Hermann, University of Gießen, and Prof. Christoph Weiss, University of Kiel, argue that consumer protection can be improved via "deregulation and market-immanent incentives".
