More specifically, my empirical research finds that both exporting and innovation are important channels for industries and individual firms to promote their productivity. I then build a theoretical model that shows how heterogeneous firms determine their choices of innovation and exports, and how these choices affect their growth and consequently the aggregate economy.To obtain empirical estimates of productivity, I perform an extended Olley-Pakes estimation, which is a semi-parametric method than can efficiently remove simultaneity and endogeneity. In "Reconsidering the Learning by Exporting Hypothesis from Innovation: An Empirical Study of US Industries," I use industry-level data of US manufacturers. I find that an industry's exports can significantly improve the industry's productivity only when its employed R&D scientists and engineers exceed 6% of all domestic employees or when its R&D funds exceed 5% of sales value. In "Empirically Revisiting the Learning-by-Exporting Theory Using Data on Chilean Manufacturing Plants," I extend my study to the plant-level. Using data on Chilean manufacturing plants, I find that only among those plants with innovation investment exceeding 100,000,000 pesos, can the consecutive exporting experience as well as the exporting ratio consistently and significantly improve the plants' productivity. Put simply, a significant learning-by-exporting effect is found only when industries or plants are investing highly in their innovation. Otherwise, the learning-by-exporting effect is neither consistent nor significant.Based on this evidence, I then provide a theoretical model to explain the dynamics of exporting and innovation behavior in my job market paper, "Exports, Innovation and Production Growth: A Dynamic and Heterogeneous Firm Model with Learning and Entry Costs." I analyze a dynamic model of a firm's joint decisions to export and innovate, allowing both decisions to affect the firm's level of production in accordance with self-selection and learning-by-exporting theories of firm-level export and production dynamics. We calibrate the model using Chilean manufacturing plant data from 2005 to 2007 and find that neither self-selection nor learning-by-exporting alone can adequately explain the observed cross-sectional relationship between firm level exports and production, favoring instead a model that requires both mechanisms to work in tandem. Counterfactual policy analysis indicates that the impact of trade liberalization on an industry depends on the maturity of the industry, the rate at which liberalization occurs, and the nature of the dominant adjustment mechanism governing firm-level export-production dynamics. 2013-07-23 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1365678129 http://rave.ohiolink.edu/etdc/view?acc_num=osu1365678129 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
