Book Description
The value impact of the two diversification strategies, namely, international and industrial diversification strategies, is one of the vastly-researched areas in the financial economics literature. In this paper, we add to diversification literature by examining the impact of each diversification strategy on the liquidity level firms choose to hold, on the propensity of firms to save cash out of their cash flow, on the tendency of firms to over-invest their free cash flow as well as on the value investors ascribe to the marginal cash within a firm. In the first essay, using fixed effect model as well as dynamic panel data model of Blundell and Bond (1998) type system GMM, we test the hypothesis that the two diversification strategies have no impact on the level of liquidity firm hold. In sample that spans from Q1Y1999 to Q4Y2005 and a sample size of 52,262 firm quarters for the fixed effect model and 20,544 firm quarters for the dynamic panel data model, we do not find any evidence that international diversification affects the liquidity level of firms. Nor do the location specific factors of the subsidiaries of internationally diversified firms, as measured by the Economic Freedom Index, have any effect on the level of cash holdings of firms. On the other hand, we find weak evidence that industrial diversification reduces the level of liquidity of firms. In the second essay, we examine the impact of the two diversification strategies on the propensity of firms to save cash out of their cash flow using a two-step GMM Instrumental Variable Regression model using a sample that extends from Q1Y1999 to Q4Y2005 and a sample size of 79,040 firm quarters. Industrial diversification reduces the propensity of firms to save cash out of their cash flow, while international diversification does not. We also examine the impact of the two diversification strategies on the overinvestment of free cash flow. In a sample of 74,914 firm quarters for the sample period of Q1Y1999 to Q4Y2005, we find evidence that industrial diversification increases the tendency of firms to over-invest their free cash flow. The third essay looks at whether the two diversification strategies have any impact on the value investors assign to the marginal dollar within a firm. Using a sample of 73,105 firm quarters for the sample period Q1Y1999 to Q4Y2005, we find evidence that while international diversification affects the value investors ascribe to the marginal dollar within the firm positively, industrial diversification affects it negatively. We also find that investors value the marginal dollar within single-segment internationally diversified as the highest and the marginal dollar within multi-segment domestic firms as the lowest within the four diversification groups.
