CSR have also been well researched upon. Innovation and Technology: The role of innovation in fostering and sustaining economic growth of nation states is now fairly well established. Innovation is the commercial introduction of new processes and products, essentially by firms. There are two different aspects of innovation that has merited the attention of researchers. First, is the generation of innovation and second is its diffusion within the economy. It was initially believed that the generation and diffusion of innovation happened in splendid isolation by the firm through its investments in R&D. However, towards the beginning of the 1990s, this view of generation and diffusion of innovation has undergone many radical changes. A number of research studies reflective these five concerns or dimensions are currently undertaken at the centre. Labour, Employment and Social Security: Research in CDS on this theme has a long history with a wide canvass, that is continuously evolving both in terms of research themes and methodological approaches. In line with the prevailing economic structures of early 1970s research in CDS had contextualised the structural transformation including agrarian transformation in Kerala and focused on questions of agrarian structure and labour relations; emerging industrial workforce and industrial relations; and labour market outcomes. Macroeconomic performance: Studies under this theme can be classified into those focusing on long term macroeconomic performance of Indian economy and those analysing short run macroeconomic issues such as monetary policy and inflation. Studies belonging to the first category focused on issues like long term growth performance of Indian economy. These studies made an attempt to identify and explain the growth phases of Indian economy. One study tries to explain these growth phases in terms of cumulative causation emerging out of positive feedback between producer services sectors and manufacturing sector. Another study examines the role of the crisis, change in economic policy regime and export performance in the growth trajectory of Indian economy. A third one analysed the relationship between public policy and economic growth in the Indian context. Migration: Linkages between migration, economic growth, income distribution, and social change. Plantation Crops: Research on plantation sector in CDS is being undertaken at the instance of the National Research Programme on Plantation Development sponsored by the Ministry of Commerce. The programme is expected to undertake policy oriented research on all aspects of plantation sector in India and help research capacity building. Politics and Development: Studies in this
