While one of the largest companies in the city quickly adopted the new technology for almost all its production, few others followed suit. Based on further investigation, the researchers conjectured that take-up was slow because employees were resisting the new technology. Cutters were paid per piece, with no incentive to reduce waste, and were concerned that the new die would slow them down and reduce their incomes. The IGC cities research programme explores the challenges of urbanisation in the developing world and the potential of cities to act as drivers of economic growth. The IGC's cities research programme is led by Edward Glaeser (Harvard University) and Gharad Bryan (London School of Economics and Political Science). 45 projects and nine events have been funded through the IGC cities programme. The IGC energy research programme analyses the role that energy plays in shaping the growth of developing countries. Within the Energy research theme, the IGC has worked on 55 projects and organised four events. The energy programme is headed by Professor Michael Greenstone (Massachusetts Institute of Technology) and Professor Nicholas Ryan (Yale University). The IGC holds a number of events throughout the year with the purpose of discussing a wide range of economic growth-related issues, sharing the findings of its research, and stimulating policy debates within the IGC's four thematic focus areas: cities, energy, state effectiveness, and firms. IGC events focus on combining research and policy and feature speakers from IGC's network of researchers and policymakers from Africa and South Asia. The IGC's flagship events are “Growth Week”, its annual conference in London, and a series of smaller regional and thematic conferences held in the UK, Africa, and South Asia with the aim of forging collaborations between policymakers and academics. In addition, a number of in-country research dissemination and policy events and workshops are held every year. The IGC also holds a number of public lectures at the London School of Economics and Political Science.
