520    This dissertation studies various aspects of economic 
       environments that are characterized by the presence of 
       externalities. Chapters 2 and 3 deal with the production 
       and dissemination of knowledge, and knowledge 
       externalities between R&D-performing manufacturing firms. 
       Chapter 4 turns to a market characterized by network 
       externalities, and studies the provision of advertisements
       to consumers by a broadcasting duopoly 
520    In chapter 2, I test the hypothesis that the mobility of 
       scientific and technical personnel is a conduit for 
       knowledge spillovers among innovative firms. Using a 
       variant of the standard Tobin's Q equation, I show that 
       firms who have access to large pools of externally created
       knowledge in their industrial and technological 
       neighborhoods enjoy additional market value as a result of
       higher scientific labor mobility, while they suffer from 
       higher mobility whenever external knowledge is limited. 
       Specifically, a percentage point increase in the mobility 
       rate increases market value by 1% to 3.1% through 
       spillovers for a firm facing the average spillover pool. 
       This effect is largely offset by a negative impact of 
       comparable magnitude 
520    In chapter 3, I study the relationship between firm size 
       and R&D productivity for a large panel of U.S. 
       manufacturing firms. I employ two measures of a firm's R&D
       performance: number of citations received per patented 
       innovation, and the number of citations received per 
       dollar of R&D expenditures. I find that citations received
       per patent exhibits no dependence on firm size, but 
       citations received per R&D dollar decreases with it. A 
       quantile regression analysis suggests that citations per 
       patent falls with firm size at the highest quantiles of 
       its conditional distribution, while showing positive 
       dependence on firm size otherwise 
520    Chapter 4 studies a model of advertising on competing 
       broadcasting channels, a market characterized by two-sided
       network externalities. Advertising is considered a 
       nuisance, but it may also intensify price competition 
       among producers depending on how information is 
       disseminated among consumers. Two classes of equilibria 
       are identified, and exclusive dealings emerge 
       endogenously. Equilibria with complete exclusivity offer 
       higher revenues for broadcasters. Surprisingly, in 
       equilibria with higher information surplus, total consumer
       surplus is necessarily lower and producer surplus is 
       higher
