Durabuild Inc., a US-based, family-owned construction company with affiliates in France, wants to recapture the high growth levels that it enjoyed in France in the decades following World War II. The founder’s grandson reflects on the economic factors that affected growth there and in the United States during that midcentury period and beyond, and he discusses with the current president (his father) whether the company should now consider expanding into China. This case explores the Solow growth model as it sheds analytic light on how various economic factors affect productivity.
