Used during my MBA studies at Pfeiffer University in Charlotte, North Carolina, the book was alwys helpful and provided me the necessary insights into the economical theory. I alredy learned the content back in Germany during my first business administration studies. Nevertheless, the American studies are more oriented towards the practical approach, so it provided me a good help to build the bridge between the economic theories, and the hands-on practical approach. We all sweated sometimes sitting over complicated formulas, but this book makes it easy to understand. A great help, as mentioned before. There is in the meantime a newer version on the market, but this one was fine for me, too. When you look for a good, solid help to understand the basics on how everything flows together, this book is a great resource!
