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 the link between a firm's quality of governance and its alliance activity. We consider alliances as a commitment technology that helps a company’ Chief Executive Officer overcome agency problems that relate to the inability to ex ante motivate division managers. We show that...

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...

We study the link between portfolio choice and different college-based interaction – defined as the one that relates the portfolio choice of an investor to that of the other investors who went to the same college. We explain it in terms of a common cultural imprinting and the development of...

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...

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 study the impact of style representation on portfolio choice using the choices of the Swedish population in their retirement accounts. We show that investor choice depends on how funds are grouped in the menu (“styles”). An exogenous increase in the style representation increases...

Trading generates not only information about the payoff of the assets traded, but also information about the traders themselves. Over time this information creates reputation. By using a unique dataset on the Treasury bond market we derive a measure of reputation. This is then used to group...
