Spiro Stefanou


Dr. Stefanou's research activities address themes of competitiveness and growth, and related policy implications.  His research revolves around how firms make decisions when current decisions impact future production possibilities.  How firms choose to adopt effective technologies and their capabilities to extract the maximum potential from these technologies is a key feature of these frameworks. Investment and innovation patterns, firm learning, and capacity utilization are key features of these investigations.  The policy stories associated with the dynamic capabilities and productivity have wide interest since growth can come from firms wasting fewer resources or adapting their size to extract the full potential of technologies in place, and/or firms looking to push the technological envelope.
