Zusammenfassung Gibt es in einem räumlichen Markt einzelwirtschaftliche und/oder gesamtwirtschaftliche, wohlfahrtstheoretische Anreize zur vertikalen Integration zweier Marktstufen in einer organisatorischen Einheit (Konzern)? Zur Beantwortung dieser Frage wird ein Modell vorgestellt, in dem...

Recent research has indicated that livestock producers who want to manage risk and diversify their operations should invest in the stock market. This research evaluates whether or not a portfolio of publicly held companies that are first handlers of pork products would provide pork producers...
