520    This dissertation is composed of three chapters. The first
       two chapters look at the productivity of knowledge workers
       who experience changes in the composition of their peers. 
       The third chapter examines compensation differences for 
       executives located in different labor markets. In each 
       case, the context in which the workers are working is 
       important for their productivity or compensation 
520    Chapter one uses large pharmaceutical mergers to 
       understand the importance of inventor networks for 
       research productivity. I compare the pre and post merger 
       patenting productivity of inventors working on different 
       types of drugs. I find that inventors working in areas 
       where the firm they are merging with is stronger have 
       larger increases in productivity as measured by both 
       patents per inventor per year and citations per patent 
520    Chapter two is joint work with C. Kirabo Jackson. Using 
       student examination data linked to longitudinal teacher 
       personnel data, we document that a teacher's students have
       larger test score gains when she experiences an 
       improvement in the quality of the other teachers in her 
       same grade and school. These spillovers are strongest for 
       less experienced teachers, persist over time and teachers 
       perform best when they are the weakest of their peer group
       --- suggesting a peer learning interpretation. 
       Conditioning on historical peer quality reduces the 
       explanatory power of individual teacher effects by twenty 
       percent 
520    In chapter three, I look at the link between location and 
       the compensation of the top executives of S&P 1500 firms. 
       I show executives working for firms headquartered in 
       metropolitan areas with more headquarters and more 
       headquarters in the same industry have higher compensation
       relative to similar executives in other cities. 
       Differences by industry headquarters persist even after 
       controlling for average levels of executive compensation 
       in each metropolitan area. I also find that executive 
       turnover is lower in cities with fewer headquarters in the
       same industry, executives who do leave are less likely to 
       find a top position at another S&P 1500 firm, and CEO's 
       are less likely to be outsiders
