The dissertation extends the line of research in the field of patent valuation by interconnecting two main strands, the evaluation of quality of patent rights based on their characteristics on one hand, and monetary valuation of patents as assets on the other hand. Moreover, the dissertation proposes and verifies the idea that the value of a patent is driven also by the ability of its owner to use the competitive advantage gained. The aim is to identify characteristics of Czech corporate patents and their owners that affect their value and to propose a way to implement this knowledge in monetary patent valuation. The effect of several ex ante and ex post indicators on patent's life was analysed employing survival analysis methods. Factors that significantly affect the lifespan of patents of Czech companies were identified using the Cox proportional hazard model. The company’s ability to benefit from competitive advantage was measured by its return on assets and return on equity, which were described by a linear mixed model. Finally, the combined effect of patent characteristics and the firm’s ability to materialize the competitive advantage on patent renewal was analysed employing the joint model for longitudinal and censored data. The results revealed positive effect on the chance of patent renewal of patent backward citation, and the concordance level between patents' technological-class codes and those of their antecedent, i.e., documents it refers to. Conversely, the size of the patent portfolio and the number of inventors have a negative effect on the chance of patent renewal. Small and medium businesses’ patents are less likely to be renewed. The effect of the patent family size, the age of the company and the patent pendency time is time-dependent, it initially lowers the chance of renewal, but its strength gradually weakens. The economic life of patents was predicted based on the results of the joint model using Monte Carlo simulation, furthermore, the implications for monetary patent and business valuation were discussed regarding its investment value.

Empirical Essays in Institutional Microeconomics

The dissertation consists of three empirical papers in institutional microeconomics. The first paper examines the role of institutional quality in international trade, the second paper focuses on unintended consequences of intellectual property rights for social welfare, and the last one addresses the impact of banking on corporate financing and investment. An introductory chapter puts these three papers into perspective. In the first paper I analyze the role of institutions in price dispersion among cities in the European region in the 1996-2009 period. Using a number of institutional quality measures I find that the better the institutions, the lower the predicted dispersion. The result is robust to different specifications of the regression model and is consistent with a hypothesis that arbitrage, as an entrepreneurial activity and the main power behind the law of one price, is influenced by institutional quality. In the second paper I use a large data set of U.S. patents applied for between 1980 and 2007 by 22 large technology companies to study development of strategic patenting over time and across industries. Using two complementary methods I reveal strong evidence against the hypothesis of more strategic patenting after 1995. Contrary to the expectations, aerospace patents appear to be on average...
