Analysis of growth, price-recovery, and productivity components (continuation of 13-31) Suppose that during 2009, the market for ZP98 grew 8%. All increases in market share (that is, sales increases greater than 8%) are the result of Dransfield’s strategic actions. Calculate how much of the change in operating income from 2008 to 2009 is due to the industry-market-size factor, product differentiation, and cost leadership. How does this relate to Dransfield’s strategy and its success in implementation? Explain.
