1. How do firms develop, grow and adjust their set of activities over time?

3. What role do interactions among a firm’s activities play in creating and sustaining competitive advantage?
To address these questions, he has employed a range of methodological approaches, including in-depth field studies of individual firms, econometric methods for large-scale data sets, formal modeling, and simulation models.
