Complementarity among International Asset Holdings: Do Banks Have a Special Role?

This paper studies the pattern and structure of cross-border bilateral financial asset holdings. By utilizing an extended dataset and employing a variant of gravity models, we find strong evidence for the presence of complementarities among bank loans, shortand long-term debts, and portfolio equity holdings. The complementarities can be explained by common factors of standard gravity models such as economy size, state of development, and information cost proxies, as well as bilateral trade in goods and services. However, we also find the presence of a direct channel of complementarities among financial asset holdings that cannot be explained by these gravity factors. We proceed to investigate whether the complementarities can be characterized by the models that predict a special role of banks in alleviating information asymmetry. We find supporting evidence for this hypothesis in that international bank lending tends to increase the volume of portfolio asset holdings. This acceleration effect of bank lending is stronger for destination countries with higher degrees of ‘law and order,’ which suggests that cross-border bank lending may not lead to capital market integration, despite reduced information cost, if there is no appropriate infrastructure to facilitate portfolio investment. By investigating the structure of bilateral asset holdings, we also find positive evidence for the information role of banks. The share of bank lending decreases with increasing state of development of destination countries measured by per capita GDP and human capital accumulation, but increases with increasing distance, suggesting that information cost may play an important role in determining the structure of cross-border asset holdings.Cross-border asset holdings; Financial integration; Bank lending

Does Licensing Resolve Hold Up in the Patent Thicket?

In a patent thicket licensing provides a mechanism to either avoid or resolve hold up. We study the choice between ex ante licensing to avoid hold up and ex post licensing to resolve it. Firms’ choice of licensing contract is studied in the context of a patent portfolio race. We show that high expected blocking leads to ex ante licensing while ex post licensing arises if expected blocking is low but realized blocking is high. Also, ex ante licensing reduces firms’ R&D incentives. A sample selection model of licensing is derived from the theoretical model. In this framework theoretical predictions on effects of blocking are tested with data from the semiconductor industry. We show that licensing helps firms to resolve blocking. However, licensing is not a cure all: it decreases as fragmentation of property rights increases and arises mainly between large firms with similar market shares. Using a treatment effects model we also confirm the prediction that ex ante licensing reduces the level of R&D investment

Incentives for Quality over Time – The Case of Facebook Applications

We study the market for applications on Facebook, the dominant platform for social networking and make use of a rule change by Facebook by which high-quality applications were rewarded with further opportunities to engage users. We find that the change led to quality being a more important driver of usage while sheer network size became less important. Further, we find that update frequency helps applications maintain higher usage, while generally usage of Facebook applications declines less rapidly with age

The Use of Trademarks in Empirical Research: Towards an Integrated Framework

This paper represents an early attempt to develop an integrated framework linking empirical studies that make use of trademark statistics. Despite its youth, this field of scholarly activity has already accumulated a critical mass of papers that allow us to draw first general conclusions about the trademark lifecycle and its impact on organisational functioning. Based on a systematic review of 64 articles with some elements of empirical trademark analysis, five broad research areas have been identified, namely: the determinants of trademark deposits; the relationship between trademarks and innovation processes; the role of trademarks in differentiating product offerings; the strategic use of trademarks; and the impact of trademarks on firm performance. Within each category, a more detailed aggregation of articles has also been proposed. Overall, the analysis has shown that the performance-based perspective currently dominates the research landscape, with studies on trademark deposits and the trademark-innovation link to follow. At the same time, there is still little known about micro-foundations of a company's trademarking behaviour; the use of trademarks and other intellectual property rights in a complementary way and its effect on value transference; as well as the performance implications of differentiation strategy. This paper considers these and other findings to outline directions for future research
