    Abstract: This paper develops a dynamic industry model in which firms compete to acquire customers over time by disseminating information about themselves under the presence of random shocks to their efficiency. The properties of the model’s stationary equilibrium are related to empirical regularities on firm and industry dynamics. As an application of the model, the effects of a decline in the cost of information dissemination on firm and industry dynamics are explored.
    Keywords: Information, industry dynamics, entry and exit, firm growth

    Abstract: This paper adapts the Crepon, Duguet, and Mairesse (1998) approach to estimate the relationship between innovation and productivity and the realities of innovative activities in developing countries. Panel data for Argentina during the period 1998-2004 to estimate a structural model in which different types of firms’ innovative behavior—including in-house activities and the incorporation of external technologies—feeds into the probability of achieving successful results in product and process innovation, which in turn explains labor productivity. The endogeneity of this three-stage process is controlled for. The results suggest that all types of innovative activities are relevant to explain success in product and process innovation, and both are important factors to explain labor productivity. Moreover, investing systematically in R&D implies an extra payoff in labor productivity. These results suggest that investing in different types of innovative activities—and not only in R&D—and doing in-house activities systematically contribute to firms’ innovative and economic performance.
