This dissertation is composed of two empirical studies on risk management. The first part is an empirical study on income risk and portfolio choice of investors. Recent theoretical work has shown that uninsurable labor income risk likely reduces the share of risky asset investment. Little empirical work has been done to examine this effect. This empirical study on the issue has three novel features. First, the long labor income history in NLSY79 is used to estimate the labor income risk. Second, the study distinguishes between permanent and transitory labor income risk, and estimates them for individuals. Third, I explicitly consider human capital as a component of the portfolio. Human capital is treated as a risk-free asset and estimated using signal extraction technique to labor income data. The study finds strong empirical support for the theory that labor income risk significantly reduces the share of risky assets in the portfolio of an investor. Furthermore, as economic theory suggests, permanent income risk has a significant effect on portfolio choice while transitory income risk has little effect. The second part of the dissertation is an empirical study on the interest rate risk management of banks. Using a rolling sample of bank holding companies from 1986 to 2002, the study investigates how banks adjust their balance sheet maturity structure according to their perception of current and future interest rate changes. Banks tend to lengthen the maturity of net assets when the yield curve is steeply sloped and shorten it when they expect the interest rate to increase in the future. To account for the off-balance-sheet activity effect on interest rate risk exposure, the sample is divided into those with high and low interest rate derivative activities. For banks with little off-balance-sheet interest rate derivative activities, the cross-sectional variation in their responsiveness of maturity structure to interest rate changes explains the stock market risk and (open full item for complete abstract)

The purpose of this study is to explore the current trends in levels of coopetition within the craft beer industry, as assessed by their engagement in collaborative efforts with their competitors in multiple geographic markets. While it is well documented that coopetition exists in small and medium-sized enterprises, especially craft breweries, it has not been studied at multiple geographical levels. The aim is to increase the scope of research and provide richer evidence of coopetitive efforts between organizations at local, regional, national levels. This study employed a non-experimental quantitative research method, using archival numerical data retrieved from publicly available databases to compare relationships between amounts of coopetition at the local, regional, and national level in the United States among breweries and 1) brewery age, 2) market saturation, 3) industry maturity, and 4) consumer social media ratings. All results other than brewery age vs. local coopetition had statistically significant relationships p < .05 and p < .01. All correlation coefficients (rs) were positive; most correlation were strong, with only market saturation at the local and regional level, and social media ratings at the national level, being of moderate strengths. These results suggest that coopetition is a beneficial practice for craft breweries. Leaders of these organizations may want to be intentional about which competitors they engage with regarding their geographic location to keep a competitive advantage in their industry.

Master of Technical and Scientific Communication, Miami University, 2003, English

To satisfy one of the requirements for the Master of Technical and Scientific Communication (MTSC) degree from Miami University, I performed a 16-week internship with Jenzabar, a higher education software provider in Cincinnati, Ohio. The purpose of this internship report is to report on and analyze the importance of effective communication in a newly merged company. The internship consisted of one major project in which Paul Anderson's Problem-Solving Model was used to update and revise content for the Jenzabar CX Web site. Additionally, this report discuses several smaller projects and looks at the limitations and expectations of communication at this company and how it affected the document development process.
