This cumulative dissertation relates three core objects of investigation within mass communication research by means of the economy. a) Economic news: News topics, tone, consonance, and volume; b) Economic sentiment: Evaluations and expectations for the economic situation of the general public and economic experts; c) Economic behavior: Purchase intention, sales and corporate advertising expenditures. Economic news not only reports on the economy but can also influence its development, since the public as well as corporate sentiment and behavior are the link between economic news and the real‐world economy. Citizens who make well‐informed economic decisions are critical for an economy. Economic sentiments of private and corporate decision makers influence entrepreneurial behavior, such as investment behavior. Advertising expenditures are part of the marketing investments of a company and in turn are essential for the funding of media systems.
