Is Carl Icahn Good for Long-Term Shareholders? A Case Study in Shareholder Activism

The increase in activist campaigns by entrepreneurial investors and hedge funds in the past decade has raised considerable debate about their benefits for average shareholders. Although critics have longed charged that the proposals for change by such active investors typically do not increase the longer-run efficiency and values of the targeted companies, more recent studies have provided evidence of success, both in terms of increasing the market value of such companies and achieving at least some of the investors' expressed objectives. This article attempts to add to these findings by examining the case of a single well-known investor, Carl Icahn, whose career as a shareholder activist now spans at least three decades. The authors report, first of all, that Icahn's targets have included companies from a remarkable variety of industries, and that his stated objectives have varied with the industries of the targets. Although more of Icahn's targets appear to have been overleveraged than underleveraged, a significant minority have had payouts ratios that were judged to be too low and more cash than they needed. In terms of Icahn's effect on other shareholders, the authors report a significant positive stock price reaction—on the order of 10%—to the announcement of Icahn's taking a position in the target firm. When examining the subsequent performance of the target firms, the authors found a very large difference between those firms that were either taken private or acquired (within 18 months)—over a third of the target companies—and those that remained independent. The authors report that although the acquired group achieved significant positive stock market returns, the firms that remained independent suffered very negative (-60%) returns. Although Icahn's proposed changes could be responsible, as critics charge, for the performance of the latter group, the authors suggest that the success of many of these companies in fending off Icahn without enacting most of his proposed reforms is a more plausible explanation. At the same time, the authors report that Icahn was successful in achieving at least one of his stated objectives in well over half of the cases in which the target companies remained independent.     

The Effects of Relative Changes in CEO Equity Incentives on the Cost of Corporate Debt

We examine how effort and risk incentives embedded in CEO equity incentives are related to the cost of debt and the role credit worthiness plays in this relationship. Our empirical approach addresses a number of unanswered questions in the literature by examining the sources and effects of co‐movements in CEO incentives, whether the proportionality of these movements is rationally priced, and whether the effects are concentrated among bonds with greater likelihood of default. Our findings confirm that effort and risk incentives are rationally priced by bond market participants. We also show that significant cross‐sectional effects are more pronounced for speculative bonds, implying that previously documented links between equity incentives and the cost of debt may not be generalizable to all debt issues.     

National Culture and the Valuation of Cash Holdings

Prior studies document that national culture traits are systematically related to cash holdings and attribute this to managerial cultural predispositions. However, it is possible that these preferences reflect investors’ cultural preferences and that managers are simply catering to investors’ preferences. It is also not clear whether the cash holding effects previously documented are value maximizing. By examining the impact of national culture traits on cash valuation, we are able to provide insight into these questions. Specifically, we examine the effect of three national culture traits – individualism, uncertainty avoidance and long‐term orientation – on firm cash valuation. Our results suggest that the previously observed effects of cultural traits on cash holdings and attributed to managerial cultural biases do not reflect investors’ preferences and are not value maximizing.     

Pakistan's agricultural exports,determinants and its potential: an application of stochastic frontier gravity model

The most important and imperative objective of the developing nations is rapid economic growth and exports are generally considered as an engine for economic growth. Being an agro-based economy, agriculture exports play pivotal role not only in economic growth but also in socioeconomic uplifting. This study aims at evaluating main determinants of agricultural exports of Pakistan by applying stochastic frontier gravity model over the period of 1995–2014 for a sample of 63 countries. In addition, the study also analyzes whether there is any untapped export potential between Pakistan and the trading partners in agriculture sector. The results confirm the consistency of gravity model for agriculture exports of Pakistan. Likewise, the estimates also point out that bilateral exchange as well as tariff rates also effect agriculture exports. The study has also incorporated the effect of common border, common culture, colonial history and preferential trading agreements by including their respective dummies. The study confirms the significance of each factor, except common language, with their respective magnitude. Moreover, technical efficiency estimates reveal that Pakistan has great export potential with neighboring, Middle Eastern and European countries.     

Price Awareness and Consumers’ Use of Deals in Brand Choice

There is evidence that consumer knowledge of prices is limited, implying that, on occasions, consumers may not be fully informed of prices when making a brand purchase. On such occasions, how do consumers make their brand choice decision? One possibility is that consumers use their expectation of prices. This raises an interesting question. To what extent is brand purchase either a function of preferences and posted prices or, of preferences and expectation of brand prices? Another important issue relates to the role of displays and features in simplifying consumer brand choice. First, do promotions cause consumers to restrict their attention to only promoted brands? Second, do promotions affect the price aware consumers more than the price unaware consumers? Our study uses scanner data on ketchup and peanut butter categories to answer the foregoing questions. We find that between 40 and 50% of the purchases are made by consumers using expectations of prices rather than posted prices. Consumers using price expectations may be thought of as being “unaware” of prices. We also find that promotions cause some consumers to focus exclusively on promoted brands, and this effect is greater on the price aware consumers than on the price unaware consumers. Our findings have an important bearing on the rationality of consumer expectation of prices, especially of the promoted brands. Price aware consumers act as a check against firms promoting without accompanying price cuts.     

Is cultural distance a bane or a boon for cross-border acquisition performance?

Literature has offered diverse explanations of the relationship between cultural distance and acquisition performance, pointing to both positive and negative effects. In this paper, we build on these findings and attempt to reconcile the conflicting research streams. We suggest that the effect of cultural distance on cross-border acquisition performance depends on the level of acquisition experience of the acquirer. More internationally experienced acquirers are more likely to be aware of cross-border acquisition pitfalls and are more skilled at resolving acquisition related conflicts; this allows the acquirer to benefit from cultural differences, ultimately leading to higher acquisition performance. Performance of culturally distant cross-border acquisitions launched by inexperienced acquirers is lower because such acquirers are unlikely to have a culturally sensitive anti-conflict action plan, which affects the ability of the acquirer to benefit fully from cultural distances. Albeit we stipulate that experience with domestic acquisitions affects positively the relation between cultural distance and acquisition performance, we do not find support. We empirically test our model with a comprehensive database of 1223 cross-border acquisitions launched during the 2009–2010 period.     

Systems GMM estimates of the Feldstein–Horioka puzzle for the OECD countries and tests for structural breaks

A systems GMM estimation method is used to estimate the Feldstein–Horioka equation from 1960 to 2007 with a panel of 13 OECD countries. It is found that the Feldstein–Horioka puzzle exists in a weaker form with a much reduced saving retention coefficient. The Bretton Woods agreement in particular seems to have weakened the Feldstein–Horioka puzzle by significantly improving international capital mobility. In comparison the Maastricht agreement seems to have improved capital mobility only by a small magnitude. The Blundell and Bond systems GMM method and structural break tests of Mancini-Griffoli and Pauwels are used in this paper.     

Intellectual property,pharmaceutical MNEs and the developing world

The paper examines the structure of pharmaceutical R&D funding, spillovers and public–private-academic research linkages in the developing countries. The paper also examines several policy options aimed at mitigating the trade off between the twin and often conflicting objectives of preserving incentives for the multinational enterprise (MNE) innovation and making patented drugs accessible to the poor countries at affordable prices. The paper argues for a vastly expanded size and scope of public-academic-nonprofit funding of R&D, whose results could become a global public good. Finally, the paper suggests that the international business scholars further explore the implications of the strong private–public-academic linkages found in the pharmaceutical research combined with the trends towards open innovation and economic development.     

US inflation and consumption: A long-term perspective with a level shift

This article examines the existence and stability of the consumption function in the United States of America (US) beginning in the 1950s. In order to obtain a stable long run relationship, we have introduced two innovative elements into the analysis of the life-cycle of the consumption function with wealth effects: 1) a shift level break in the cointegrating relationship, and 2) using inflation as an additional explanatory variable. By implementing a well structured estimation strategy, we found that after taking the level shift into account, a cointegrating equation, including inflation, exists and is more stable for the critical sub-samples than traditional consumption function models.
