"Business Model Evaluation: Quantifying Walmart's Sources of Advantage." Strategic Entrepreneurship Journal (forthcoming).1932-4391http://nrs.harvard.edu/urn-3:HUL.InstRepos:13135315We develop an analytical framework on the basis of the economics of business performance to provide quantitative insight into the link between a firm's business model choices and its profit consequences. The method is applied to Walmart by building a qualitative representation of its business model and mapping that representation on an analytical model that quantifies the company's sources of advantage over time. The analysis suggests that the effectiveness of a particular business model depends not only on its design (its levers and how they relate to one another) but also, most importantly, on its implementation (how the levers are pulled).en-USbusiness modelcompetitive advantageprofitJournal Article2014-10-2410.1002/sej.1190
