Amihud and Lev (1981) are widely cited as providing evidence that managers, unless closely monitored by large block shareholders, will attempt to reduce their employment risk through unrelated mergers and diversification. These corporate strategies, however, may not be in shareholders' interests. Reconsidering the agency assumptions underlying Amihud and Lev's study and the methodology they used, we develop hypotheses regarding the association between ownership structure, board vigilance, corporate strategy, and corporate performance from management theory and test them using Amihud and Lev's data from the 1960s and new data from the 1980s. Neither study supports the conclusions of Amihud and Lev, nor the agency theory belief that monitoring efforts by principals affect the strategic behaviors of agents or the performance of firms that they manage. © 1998 John Wiley & Sons, Ltd.  相似文献

We quantify, using data from the World Bank’s Enterprise Surveys and the World Economic Forum’s Global Competitiveness Index, the empirical relationship between global competitiveness and R&D investment activity as well as the independent relationship between global competitiveness and R&D investments across geographic regions of economic development. We also explore alternative measures of the effectiveness of R&D investments. Our findings suggest that R&D investments are a possible policy target variable in high-income regions for policy makers to consider for increasing firms’ global competitiveness.

In this study, we find that foreign firms cross-listed in the US issue significantly more and better-quality management earnings forecasts after their home countries sign the Multilateral Memorandum of Understanding Concerning Consultation and Cooperation and the Exchange of Information (MMoU), a nonbinding arrangement established by the International Organization of Securities Commissions to enhance the cross-border enforcement of securities laws. Specifically, we find that after the MMoU, relative to their domestic counterparts in the US, foreign firms cross-listed in the US are not only more likely to issue management earnings forecasts but also issue them more frequently. They also tend to issue better-quality earnings forecasts, as measured by lower surprise, higher precision, greater timeliness, more disaggregation, lower optimism and fewer errors. We find that the observed effects of the MMoU signing are stronger for cross-listed firms from countries with weaker institutional environments, resulting in greater enforcement concerns after the MMoU, and for firms with less foreign institutional ownership before the MMoU. Collectively, our findings support the conjecture that after a US-listed foreign firm's home country enters the MMoU, the firm has more incentives to engage in voluntary disclosure due to greater concerns about regulatory enforcement and increased information demand from investors.  相似文献
