    Abstract: This paper exploits a particular facet of the US patent system, which thus far has been overlooked in the literature: the patent renewal fee scheme relating to switches from small to large entity status. Based on this observation, we are able to determine whether university patents are licensed over their enforceable lifecycle and at what point in time the licensing occurs. We find that while the funding source of patented inventions makes no difference to the propensity of an academic patent being licensed, federally sponsored patents are less likely to be licensed early compared to their non-federally funded counterparts.

    Abstract: This paper analyzes the effect of imitation on the rate of technological progress in an endogenous growth model. Quality leaders protect themselves from imitation by secondary development, which increases technological progress. Nevertheless, lower intellectual property rights protection reduces the incentives to enter the research sector which reduces innovation by outsiders. Simulations show that the net effect of increased imitation on the growth rate is ambiguous - it can be positive, negative, or inversely U-shaped, depending on the productivity of secondary research. Lower patent protection also reduces the degree of market power in the economy so that output, the wage rate, and welfare is typically increased.

    Abstract: This study compares the innovation process of a privately-owned enterprise and a state-owned enterprise in China using their patent data. Huawei and ZTE were selected for this study because they experienced the same historical environment in the same industry from the same region in China leaving their owner types as their critical difference. This study investigates the difference in the innovation process in R&D between a privately-owned and a state-owned enterprise by analyzing (1) domestic and international patent application pattern, (2) co-application and co-applicants, (3) knowledge accumulation inside Huawei and ZTE, and (4) knowledge spillover to domestic and foreign firms.
    Keywords: China, Business enterprises, Government enterprises, Telecommunication, Research & development, Technological innovations, Patent data, Privately-owned enterprise, State-owned enterprise

    Abstract: This paper studies the diffusion of knowledge and its consequences for local innovation production. In a common framework, we analyze the geographic reach of different channels of knowledge flows that thus far have been studied separately in the literature. To jointly estimate these flows, we develop and apply novel econometric techniques appropriate to the nature of the data. We find that geographic along with technological proximity to be more essential to the operation of market than to non-market channels of knowledge flows. External accessible disembodied knowledge has a strong positive effect on local innovation production as large as that of homegrown knowledge.
    Keywords: knowledge flows, patents, citations, inventor mobility, trade, non-linear regression systems

    Abstract: Objectives: To assess whether the addition of a peer testimonial to an informational mailing increases conversion rates from brand-name prescription medications to lower-cost therapeutic equivalents, and whether the testimonial’s efficacy increases when information is added about an affiliation the quoted individual shares with the recipient. Research Design and Methods: 5,498 union members were randomly assigned to receive one of three different informational letters: one without a testimonial (No Testimonial Group), one with a testimonial from a person whose shared union affiliation with the recipient was not disclosed (Unaffiliated Testimonial Group), and one with a testimonial from a person whose shared union affiliation with the recipient was disclosed (Affiliated Testimonial Group). Results: The conversion rate for the No Testimonial Group was 12.2%, which is higher than the Unaffiliated Testimonial Group rate of 11.3% and the Affiliated Testimonial Group rate of 11.7%. The differences between the groups are not statistically significant. Conclusions: Short peer testimonials do not increase the impact of a mailed communication on conversion rates to lower-cost, therapeutically equivalent medications, even when the testimonial is presented as coming from a more socially proximate peer.

    Abstract: We analyze how rebranding affects depositor discipline in a sample of Turkish banks. Depositor discipline refers to the empirical regularity that banks with higher capitalization attract more deposits at lower cost. Bank rebranding tends to increase depositor discipline, especially when there is only a small cosmetic change to the name. Rebranding a Turkish named bank into a foreign named one is associated with increased depositor discipline. In a similar manner, depositor discipline tends to decrease in the short-run if the bank rebrands from a foreign name to a Turkish one. These results suggest the presence of depositor ethnocentrism. Our main findings are robust to controls for major ownership changes and for selection effects.
    Keywords: depositor discipline; rebranding; banks
