Static tradeoff theories, which do not explicitly treat the impact of transaction costs, do not explain the policy of asymmetry between frequent small debt transactions and infrequent large equity transactions. Nor do these theories explain why the debt ratio is allowed to wander a considerable distance from its alleged static optimum, or how much of a distance should be tolerated. We offer a class of diffusion models that mimic this behaviour in a stochastic-dynamic framework and are designed to optimize a financing strategy using any static tradeoff theory as input. The models developed reveal the determinants of the size and frequency of equity transactions and the range of values over which leverage variations are tolerated in four generic scenarios. They also yield a new formulation of the cost of capital that recognizes stochastic transaction costs and a penalty for deviation from any static-optimal leverage. Our class of models augments the pecking order theory, provides a flexible quantitative framework for its implementation as a decision tool, and facilitates the formulation of additional hypotheses for its empirical validation. Symmetrically, our results show the importance of dynamic factors in designing and interpreting empirical tests of static tradeoff theories. The results presented have important implications for the role played by static tradeoff theories in a stochastic-dynamic framework. One such implication is that the static-optimal leverage has no direct effect on the firm's leverage policy in this setting. The target leverage for refinancing transactions is different from the static-optimal leverage, and the mean leverage is generally different from both. As a consequence, the latter cannot be used to estimate the former. Another implication is that even when the mean leverage equals the static optimum, mean reversion is not an optimal behaviour and therefore not a legitimate test for the existence of a static tradeoff in a dynamic context. Still another implication is that wide variations in leverage ratios cannot be interpreted as evidence of leverage indifference. It follows that the pecking order theory is consistent with static tradeoff theories and does not require the assumption of leverage indifference.  相似文献

This article develops a theory concerning the choice between standard promotion practices and up‐or‐out contracts. Our theory is based on asymmetric learning and promotion incentives. We find that firms employ up‐or‐out contracts when firm‐specific human capital is low and standard promotion practices when it is high. We also find that, if commitment to a wage floor is feasible and effort provision is important, up‐or‐out is employed when low‐ and high‐level jobs are similar. These results are consistent with many of the settings in which up‐or‐out is typically observed, such as law firms and academia.  相似文献

Using design and communication principles, this study uses a content analysis design to evaluate all active blogs from the 2011 Fortune 500 list (n = 125). The results indicate that corporate America has only modestly incorporated the dialogic principles into their blogs. Current corporate blogs are well-designed as far as making them searchable and easy to navigate; however, the blogs are mostly being used to provide information in a one-way manner rather than creating an open dialogue with consumers. While blogging can enhance relationships with stakeholders, corporate communicators must strive to develop legitimate conversations with their blog readers.  相似文献

Qualitative input–output (IO) analysis can be considered mostly in terms of a graph-theoretic formulation, which involves the construction and use of an adjacency matrix, derived from a binary transformation of the IO coefficient matrix. Classical attempts at qualitative IO analysis have derived the structure from the direct IO coefficient table. In more recent attempts, greater sophistication has been achieved by incorporating a degree of quantification into the qualitative analysis. Also, the concept of important coefficients (IC) has been used for the construction of the adjacency matrix. The present study is carried out along these lines for the Indian economy.  相似文献

For current status data, L IN , O AKES and Y ing (1998) proposed a procedure for estimation of the regression parameters in the additive hazards model that makes clever use of martingale theory. However, one of the outstanding problems posed in the paper was the issue of efficient estimation, as their estimators do not attain the semiparametric information bound. In this paper, we explore this issue and provide a characterization of the NPMLE. We conduct efficiency comparisons between the NPMLE and the procedure of L IN et al . (1998) analytically and numerically through analysis of a dataset from a tumorigenicity experiment.  相似文献

American depositary receipts (ADRs) are negotiable instruments representing foreign company shares traded in US dollars in the US capital market. We present comparative analyses of the pricing and aftermarket performance of Initial Public Offerings (IPOs) by ADRs and a matching sample of US firms over the 1990–2001 period. Offered by large, well-known multinationals, ADR IPOs go through a detailed scrutiny, and incur significant costs, during the pre-IPO period to recast financial statements in conformity with SEC rules and the US GAAP. This mitigates the information asymmetry between the IPO firm and investors. We categorize the ADR issuing country as developed or emerging, and our sample includes several cases of privatization of state owned corporations. The analyses indicate that (1) ADR IPOs are significantly less underpriced than comparable US IPOs; (2) IPOs from developed countries are more underpriced; and (3) Privatization IPOs are less underpriced than non-privatizations. The lower underpricing of ADR IPOs persists even after differential IPO attributes, the traditional proxies for information asymmetry and, the unique characteristics associated with ADR IPOs, are accounted for. We conclude that extant literature offers only partial explanation for this puzzling phenomenon.  相似文献

The paper employs a sample of listed Indian manufacturing firms over the period 1995–2004 to examine the factors influencing the concentration of bank debt in total debt. The results indicate that the factors vary by firm size. Small to medium-sized firms have a high concentration of bank debt. The results support the reputation view that firms face differential debt choice as they grow larger. When evaluating bank regulations, policymakers need to consider the importance of the reputation-building service which banks provide to businesses.  相似文献
