The present chapter examined the behavior of relative wage rate, productivity of labor, and total factor productivity growth (TFPG) and also attempted to explore the causal relationship between relative wage rate and productivity of labor as well as relative wage rate and TFPG in food and beverage industry in India over the period 1980–1981 to 2017–2018. The result of Sen (2003) approach of endogenous structural break suggests that the series of relative wage rate, productivity of labor, and TFPG follows trend stationary process. A significant break is found for all the three aforementioned variables, being 1984–1985 for relative wage rate and productivity of labor whereas 2007–2008 for TFPG. For the three variables, growth rate has increased after the break. Bidirectional causality between relative wage rate and productivity of labor as well as relative wage rate and TFPG is evident.

This chapter introduces the development of the Indian pharmaceutical industry (IPI) in different phases such as till the 1970s, with the modification of the Indian Patent Act 1970, i.e. after the 1970s, with the trade liberalisation and the signing of Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement and in the product patent regime, i.e. since 2005. This chapter also discusses the position of IPI in the global economy along with the top medicine-producing countries in the world. The objectives of the present study are presented separately with the firm-level data, state-level data as well as All India and global-level data. All the research questions are also presented in this chapter related to the firm-level data, state-level data as well as All India and global-level data. Then the relevance of the present study in the existing literature is discussed considering each of the book chapters separately while outlining the structure of the present study.
