Stock returns and the Miller Modigliani valuation formula: Revisiting the Fama French analysis

Fama and French (2006) use the dividend-discount model to develop the role of expected profitability, expected investment, and the book-to-market ratio as predictors of stock returns. One reported empirical result is anomalous. The valuation model establishes that the comparative static relation between expected returns and expected investment is negative, yet it appears to be positive and insignificant. We show that the posited valuation relations apply at the firm level, and not at the per share level at which they were tested. Once the variables are measured at the firm level, all the Fama French predictions are validated.     

Interrelationships between environmental dependencies: A basis for tradeoffs to increase autonomy

General managers of large industrial plants in Israel were asked to evaluate the effects of environmental dependencies on their freedom of action. It was found that most segments of the environment were perceived as homogeneous—affecting the firms' autonomy in similar ways. Different components of government, however, were perceived as having conflicting interests both within the segment and with other segments of the environment. When a segment of the environment is heterogeneous, it is possible that managers use a tradeoff strategy, in which pressures generated by one component of the environment can be used as a means to reduce pressure of the other components.     

Entrepreneurial Orientation and International Performance: The Moderating Effect of Decision‐Making Rationality

This research examines how entrepreneurial orientation (EO) influences international performance (IP) of the firm taking into account the moderating effect of decision‐making rationality (DR) on the EO–IP association. Such an investigation is significant because it considers the interplay of strategic decision‐making processes supported by the bounded rationality concept in the entrepreneurship field. Drawing from a study on activities of 216 firms in the United States and United Kingdom, the evidence suggests that DR positively moderates the EO–IP association. The findings suggest that managers can improve IP by combining EO with rational (analytical) processes in their strategic decisions.     

Testing the growth option theory: the profitability of enhanced momentum strategies in Australia

Recent literature relates growth option theory to various return regularities. Sagi and Seasholes (2007) (S&S) develop a model that explains momentum profitability using growth option theory. We test the model’s predictions in the Australian market by examining three momentum strategies. Two of these strategies examine the profitability of momentum strategies conditioned on stocks characteristics, whereas the third conditions on previous market returns. Our results are largely supportive of the S&S model. As predicted by S&S, the two strategies that use firm‐specific characteristics yield a higher profit than a simple momentum strategy. The third strategy that conditions on the previous market return also leads to differences in momentum profitability between bull and bear markets, but these differences are small and largely insignificant.
