    Tariff Rates, Offshoring and Productivity: Evidence from German and Austrian Firm-Level Data

    This paper studies the impact of trade liberalization in terms of tarif cuts within the Eastern European enlargement on German and Austrian firm productivity. Unique matching of data from 1994 to 2003 suggests that tarif reductions raise parent firm productivity significantly. A ten percentage point decrease in tarif rates can lead to total factor productivity gains of up to 2 percent. The data allow distinction between three types of tarifs: output, intra-firm and input tarif rates. The size of the results strongly depends on the type of tarif and country analyzed

    Exports and Productivity: An Empirical Analysis of German and Austrian Firm-Level Performance

    This paper studies the relationship between export activities and firm-level productivity. Unique matching of German and Austrian micro data from 1994 to 2003 suggests that exporters are more productive by around 40 percent compared with non-exporters. Moreover, beside other analysis techniques, instrumental variable estimations suggest that exporting causes a rise in firm-level productivity. That is, the annual average growth rate of an exporting firm's productivity is between about 1 and 1.5 percent higher than that of non-exporters. It allows the conclusion that, against other findings of existing studies, both directions hold: more productive firms self-select themselves into export markets and being active in foreign markets boosts firm-level productivity

    IDENTIFYING MECHANISMS OF HOST PLANT SPECIALIZATION IN \u3cem\u3eAPHIS CRACCIVORA\u3c/em\u3e AND ITS BACTERIAL SYMBIONTS

    Many insects form close relationships with microbial symbionts. Insect symbionts can provide novel phenotypes to their hosts, including influencing dietary breadth. In the polyphagous cowpea aphid, Aphis craccivora, the facultative symbiont Arsenophonus improves aphid performance on one host plant (locust), but decreases performance on other plants. The goal of my thesis was to investigate the mechanism by which Arsenophonus facilitates use of locust. First, I assembled an Aphis craccivora-Arsenophonus-Buchnera reference transcriptome to conduct RNAseq analysis, comparing gene expression in aphids feeding on locust and fava, with and without Arsenophonus infection. Overall, few transcripts were differentially expressed. However, genes that were differentially expressed mapped to a variety of processes, including metabolism of glucose, cytoskeleton regulation, cold and drought regulation, and B-vitamin synthesis. These results imply that Arsenophonus is producing B-vitamins, which might be deficient in locust. In a second set of experiments, I used qPCR to test whether symbiont function across host plants might be mediated by bacterial titer. I measured relative Arsenophonus abundance across plants, and found Arsenophonus titer was variable, but generally greater on locust than fava. In summary, my results suggest that Arsenophonus synthesis of B-vitamins should be further investigated and may be mediated by bacterial titer

    Innovation and the International Firm Structure: Theory and Evidence from German Firm-Level Data

    Get PDF
    This paper studies the impact of innovation on the organizational structure. The theoretical framework predicts that a larger parental pool of knowledge raises the probability of oshoring. This holds in a national as well as an international context. However, when the producer loses territorial protection, the changeover from non-integration to integration is delayed. Employing data on German rms investing in Eastern Europe nds empirical evidence for the theoretical predictions. The results are robust to dierent measurements and an instrumental variable regression.offshoring; innovation; firm structure
