Michael Porter's Five Forces Model
The IBISWorld United States database includes reports on more than 700 industries. These reports are based loosely on Michael Porter's Five Forces model and may be helpful for students doing industry analyses. For example, the Products & Markets section of the reports typically discuss demand determinants, while the Competitve Landscape section covers topics such as barriers to entry, the basis of competition, and industry concentration.
IBISWorld is a licensed Rod Library database and can be accessed directly at this URL which works from on-campus and off-campus (will be prompted for UNI CatID if off-campus): http://www.library.uni.edu/gateway/owl/ibisworld-united-states
A second licensed database, the Small Business Reference Center, also includes industry reports. Some reports published by Datamonitor include explicit Five Forces analysis. A full text search for "five forces" turns up reports such as Breakfast Cereals Industry Profile, for example. This database also can be accessed from the Business Portal and Databases A-Z.
Other databases listed under the Industries & Markets tab on the Business Portal may lead to industry/market reports or articles from academic journals, trade journals, and business magazines that would be useful in five forces analysis of a given industry.
