Corporate diversification is a core topic in Financial Economics. The desire to better understand why a firm elects to diversify as opposed to increase in scale is the motivation of this dissertation. To accomplish this goal I test a number of dynamic models of corporate diversification, with similar predictions, to better understand the dynamic choice to diversify. I find that several previously untested models do indeed provide insight as to why a firm would diversify (Essay One). In particular two firm traits, firm talent which I use the proxy of organization capital and asset specificity which I use the proxy of asset tangibility, are strongly related to propensity of the firm to engage in corporate diversification for the first time. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2015 / FAU Electronic Theses and Dissertations Collection
