We study the effects of financial innovation in a model of endogenous information acquisition. We determine the conditions under which the introduction of a derivative written on an existing stock increases or decreases the incentive to purchase information. We show that financial innovation produces some effects which hold across informational structures and others which differ. The former coincide with the few empirical results that are robust in the literature (effects on prices, risk premia, and volatility), while the latter coincide with the ones that differ experiment by experiment (effects on volume, correlation between volume and volatility, and market informational efficiency).

We study how a firm's decision to offer bonds of various maturities affects the portfolio allocations of institutional investors. We argue that because of lower information-collection costs, institutional investors tilt their portfolios towards firms that offer bonds of various maturities. We show that this translates into lower bond yields, both in the primary and in the secondary bond markets.

Commercial banks acquire inside information about the firms they lend to. We study the impact of this informationally privileged position on the borrowing firm using a broad panel of U.S. firms over the 1993–2004 period. We measure the strength of the bank-firm relationship by bank-firm proximity, size of the loan, and the lender's insider potential. We show that a stronger relationship, by inducing better monitoring, improves the borrower's corporate governance. Simultaneously, it makes the bank a potentially more informed agent in the equity market. This information asymmetry increases adverse selection for the other market participants and lowers the firm's stock liquidity. This trade-off between improved corporate governance and greater information asymmetry affects the firm's value. Our results have normative implications for the role of banks in the development of financial markets.

We study the impact of contractual incentives on the performance of mutual funds. We find that high-incentive contracts induce managers to take more risk and reduce the funds' probability of survival. Yet, funds with high-incentive contracts deliver higher risk-adjusted return, and the superior performance remains persistent. The top incentive quintile of funds outperforms the bottom quintile by 2.70% per year. Moreover, high-incentive winner funds from one year have a positive alpha of 0.41% per month in the following year. Focusing on funds' holdings, we show that active portfolio rebalancing is the main channel through which incentives increase performance. The Author 2008.

This article studies one of the potential causes of the financial market bubble of the late 1990s: the herding behavior of mutual funds. We show that the incentives contained in the mutual funds' advisory contracts induce managers to overcome their tendency to herd. We argue that investing in bubble stocks amounts to herding and contracts with high incentives induce managers to diverge from the herd, thus reducing their holding of bubble stocks. The differential exposure to bubble stocks significantly impacted the funds' performance both in the period prior to March 2000, as well as afterwards.

Traditional portfolio balance theory derives a downward sloping currency demand function from limited international asset substitutability. Historically, this theory enjoyed little empirical support. We provide direct evidence by examining the exchange rate effect of a major redefinition of the MSCI Global Equity Index in 2001 and 2002. The index redefinition implied large changes in the representation of different countries in the MSCI Global Equity Index and therefore produced strong exogenous equity flows by index funds. Our event study reveals that countries with a relatively increasing equity representation experienced a relative currency appreciation upon announcement of the index change. Moreover, stock markets that are upweighted (downweighted) feature a higher (lower) permanent comovement of their currency with the basket of other MSCI currencies.

We exploit the merger between BlackRock and Barclays Global Investors to study how changes in expected ownership concentration affect the investment behavior of funds and the cross-section of stocks worldwide. We find that funds with open-end structures and large exposure to commonly held stocks begin avoiding these stocks following the merger announcement. This leads to a permanent change in the composition of institutional ownership and a negative price and liquidity impact. We confirm these results in a large sample of global asset management mergers. Our findings suggest that market participants behave strategically in response to changes in expected financial fragility.

We study holdings in M&A targets by financial conglomerates which affiliated investment banks advise the bidders. We show that advisors take positions in the targets before M&A announcements. These stakes are positively related to the probability of observing the bid and to the target premium. We argue that this can be explained in terms of advisors, privy to important information about the deal, investing in the target in the expectation of its price to increase. We document the high profits of this strategy. We also document a positive relationship between the advisory stake and the deal characteristics. The advisory stake is positively related to the likelihood of deal completion and to the termination fees. However, these deals are not wealth-creating: there is a negative relation between the advisory stake and the viability of the deal. These results provide new insights into the conflicts of interest affecting financial

We study the role of institutional investors in cross-border mergers and acquisitions (M&As). We find that foreign institutional ownership is positively associated with the intensity of cross-border M&A activity worldwide. Foreign institutional ownership increases the probability that a merger deal is cross-border, successful, and the bidder takes full control of the target firm. This relation is stronger in countries with weaker legal institutions and in less developed markets, suggesting some substitutability between local governance and foreign institutional investors. The results are consistent with the hypothesis that foreign institutional investors act as facilitators in the international market for corporate control; they build bridges between firms and reduce transaction costs and information asymmetry between bidder and target. We conclude that cross-border portfolio investments of institutional money managers and cross-border M&As are complements in promoting financial integration worldwide.

We study the effects of the controlling shareholders' portfolio diversification on the initial public offering (IPO) process. Less diversified shareholders have more to gain from taking their firm public, and are more willing to accept a lower price for shares. We test these hypotheses using the data on all IPOs in Sweden between 1995 and 2001. Using detailed information on the portfolio composition of shareholders in private and public firms, we construct several proxies of their portfolio diversification and relate them to the probability of the IPO and the underpricing. We show that the less diversified individual shareholders, especially those with lower wealth, sell more of their shares at the IPO. Firms held by less diversified controlling shareholders are more likely to go public, and exhibit higher underpricing. These effects are economically and statistically significant, while the diversification of noncontrolling shareholders has no effect. Our findings suggest that diversification of controlling shareholders plays a prominent role in the IPO process.
