I am a Ph.D. candidate in Economics at Purdue University working with Professor Stephen Martin. Prior to attending the Ph.D. program at Purdue, I earned a BA in Mathematics and Economics from Berea College in Berea, KY.
My research interests include Industrial Organization, Corporate Finance, Health Economics, International Economics, and Applied Econometrics. Currently, my research focuses on mergers & acquisitions, innovation, health industries, and diffusion of know-how across borders.
As a Ph.D. candidate, I have taught Principles of Economics and Macroeconomics at Purdue University, and have been named the Distinguished Graduate Student Instructor based on student evaluations.

"The Impact of Mergers and Acquisitions on Innovation"
I analyze the impact of acquisitions on innovation employing the fixed effects negative binomial modeling approach. I find that, consistent with the efficiency gains argument, merging firms generate more useful knowledge at a lower cost after the merger. Further, mergers involving a large and a small firm, compared to any other combination, produce the highest number, as well as the most widely cited set, of patents, likely due to easing of financial constraints. Finally, among merging firms, complementarity of ex-ante innovative agendas fosters a higher level of innovation after the merger. Results are economically large and robust to numerous sensitivity checks.

"A Perfect Recipe for Disaster: A Retrospective Analysis of the Boston Scientific and Guidant Merger"
Boston Scientific posted a loss of $4.26 billion in the quarter following its acquisition of Guidant. Fortune magazine described the deal as the second worst deal ever. To this day Boston Scientific is writing off goodwill associated with overpaying for Guidant. I retrospectively analyze the outcomes of this merger, along with its impact on market shares and consumer welfare. I explore how the largest acquisition in the medical devices industry changed the market structure, competition, and innovative activity of the surviving and the rival firms. By studying a case of a single acquisition, I am able to dig deeper and gain insights on the characteristics of the merging entities and the processes through which useful resources are combined and duplicates are eliminated that may have led to undesirable post-acquisition outcomes. Lessons learned from this example will be useful in deepening our understanding of why mergers fail and will be valuable from the regulation point of view.
"Taxes and Firm Value – Evidence from the Ex-Dividend Day Stock Price Behavior"
This paper analyzes the behavior of ex-day stock prices when one of the imperfections is naturally removed as a result of the U.S. tax legislation and attempts to observe if the ex-day price drop is affected by taxes. The new law, by equating the capital gains tax with taxes paid on dividends, provides for an ideal condition under which the interaction between the ex-day price behavior and taxes can be examined by comparing the test-statistic developed by Elton and Gruber (1970) from the periods before and after the new tax law was enacted. Consistent with the tax-effect hypothesis, I find that the price change (from the day before the ex-day to the ex-day)-to-dividend ratio increased significantly after the elimination of preferential tax treatment of capital gains. Moreover, this evidence also contrasts the short-term trading hypothesis, since the new law did not change the tax incentives of short-term traders. The fact that I observe a significant change shows that the market is not dominated by short-term traders; instead the marginal stockholders are individual investors.
