We exploit the restrictions of intertemporal portfolio choice in the presence of non-financial income risk to design and implement tests of hedging that use the information contained in the actual portfolio of the investor. We use a unique dataset of Swedish investors with information broken...

We relate the degree of investor portfolio focus to the broader urban economic context of the household. Using a detailed panel of investors in Sweden over the period 1995 to 2000, we find that the level of investor diversification, as measured by number of stocks in the portfolio and by the...

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...

We study holdings in merger and acquisition (M&A) targets by financial conglomerates in 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...

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...

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 examine how shareholder investment horizons influence firms’ payout decisions. We find that US firms held by short-term institutional investors have a higher propensity to buybacks shares instead of using dividends. Firm managers seem to respond to the preferred payout policy of investors...

We study IPOs by focusing on the degree of portfolio diversification of the shareholders taking the company public. We argue that a less diversified shareholder has more to gain from taking the company public and would be more willing to accept a lower price for the sale of its shares, i.e....

We study how competition in the mutual fund industry affects stock market liquidity. We argue that mutual fund families operate as multi-product firms, jointly choosing fees, performance and number of funds and sharing common research facilities. The family-based organization generates economies...

We study the puzzle of portfolio underdiversification and proximity investment from a novel perspective, linking it to the process of urbanization. We find that urban portfolios are more focused – i.e., less diversified and more concentrated in ‘close’ stocks. We explain it in terms of the...
