Die Bedeutung von Emotionen und Affekten bei ökonomischen Entscheidungen wird seit mehreren Jahren in der ökonomischen Literatur diskutiert (z. B. Rabin, 1998). Eine Erklärung der empirischen Evidenz in diesem Bereich, die über eine bloß phänomenologische Ebene hinausgeht, verlangt eine...

Within the last three years, Google has acquired YouTube and DoubleClick and has attempted to control part of Yahoo!'s search advertising business. Two of the deals have not raised antitrust concerns by competition authorities. I review these deals with a focus on consumer welfare. Consumers are...

Yet, production costs and quality both result from R&D efforts and therefore are both uncertain. I characterize the...

In a market environment with random detection of product quality, a firm can employ umbrella branding as a strategy to convince consumers of the high quality of its products. Alternatively, a firm can rely on external certification of the quality of one or both of its products. We characterize...
