Dispersion in German Manufacturing Industries
نویسنده
چکیده
Empirical research has shown tremendous productivity di erences, even within narrowly de ned industries. A great host of studies is explainsing this productivity disparity by factors such as idiosyncratic technology shocks, input price di erences, management skills, or international trade. Although these explanations are undoubtedly important, the current paper suggests that product diversi cation strategies of rms can also play an important role. Using a matched producer-product panel dataset of German manufacturing industries over the period 2003-2006, we nd that the average degree of product diversication across industry establishments is positively related to within-industry labor productivity dispersion. JEL classi cation: L11, L22, L25

Entry, Exit and Productivity: Empirical Results for German Manufacturing Industries Using panel data from Spain Farinas and Ruano (IJIO 2005) test three hypotheses from a model by Hopenhayn (Econometrica 1992): (H1) Firms that exit in year t were in t-1 less productive than firms that continue to produce in t. (H2) Firms that enter in year t are less productive than incumbent firms in year t. (...
متن کاملProduct Substitutability and Productivity Dispersion
Tremendous differences in producer productivity levels exist, even within narrowly defined industries. This paper explores the influence of product substitutability in an industry on this disparity. When consumers can easily switch between producers, relatively inefficient (highcost) producers cannot profitably operate. Thus high-substitutability industries should exhibit less productivity disp...
