This study offers several new perspectives on the effects of competition in takeover contests on bidder returns. Using a more extensive database than existing studies and employing several different measures of success in takeovers, we find that success in competitive acquisitions decreases shareholder wealth relative to both failure and success in observed single-bidder takeovers. Further, we consider and test hypotheses regarding bidder returns, including hypotheses suggested by the preemptive bidding theory. In general, our results neither support the preemptive bidding theory nor the hypotheses linking the method of payment and the observed level of competition. We also test hypotheses relating to returns across the multiple events in a multiple-bid contest that competition among bidders generates. The results of these tests underscore the importance of timing as well as success of a bid to the bidder's subsequent performance.

This paper examines foreign institutional investors’ portfolio allocation and performance in US securities. We test how information immobility, proxied by information barriers between the investors’ home markets and the US, influences portfolio strategies. Consistent with theoretical predictions, foreign institutional investors’ total investment in the US is negatively related to information immobility. Similarly, information immobility is a significant driver of portfolio under-diversification across industries. Industry concentration has declined over time, consistent with declining search costs. Industry-concentrated portfolios outperform more diversified portfolios for both foreign and US institutional investors. Concentration especially helps institutional investors with the easiest access to information.

Cross-bolding occurs when listed corporations own securities issued by other corporations. We analyze the effect of cross-holdings on market capitalization and return measures as well as implications for econometric testing of asset pricing theories. We show that cross-holdings generally distort standard market return and risk measures. The magnitudes of such distortions are calculated for simulated economies by using a variety of cross-holding patterns. In addition, cross-holdings are shown to induce nonstationarity in the covariance matrix of security returns. We examine the effect of this nonstationarity for estimating efficient frontiers and factor structures. We also discuss the implications for risk-return estimates in equilibrium asset pricing models.

We investigate determinants of international diversification in institutionally managed portfolios from more than 60 countries. Survey-based country-specific variables on cross-cultural behaviors help to explain both home bias and diversification among foreign equities. In particular, investment funds from countries characterized by higher uncertainty avoidance behavior display greater home bias and are less diversified in their foreign holdings. Portfolios from countries with higher levels of masculinity and long-term orientation display lower levels of home bias, and portfolios from countries with higher levels of masculinity are more diversified abroad. Portfolios from culturally distant countries invest less abroad and underweight culturally distant target markets. The economic significance of cultural variables is high and comparable in magnitude to geographical distance, a consistent influence on foreign diversification in prior studies. Culture impacts investor behavior directly and not merely though indirect channels such as legal and regulatory framework.

Using data on security holdings for 10,771 institutional investors from 72 countries, we test whether concentrated investment strategies result in excess risk-adjusted returns. We examine several measures of portfolio concentration with respect to countries and industries and find that portfolio concentration is directly related to risk-adjusted returns for institutional investors worldwide. Results suggest, in contrast to traditional asset pricing theory and in support of information advantage theory, that concentrated investment strategies in international markets can be optimal.
