I examine local bias in hedge fund portfolio selection, using Section 13-F original and confidential holding filings. Using Coval and Moskowitz (1999) measure, I find that local bias is present among U.S.-based hedge funds. The holdings of funds are on average 20-67 km closer to hedge funds than the market. I also find that size and leverage of a company serve as determinants of local bias, with the preference of hedge funds for smaller and more levered local companies. I suggest an alternative model for assessment of local bias that yields results further supporting the hypothesis of the existence of local bias among hedge funds. I do not find a positive effect of local bias on performance. Moreover, in some periods I find a strong negative effect of local bias both on raw and risk-adjusted returns. I argue that these findings suggest that the origins of local bias should not be looked for in information asymmetry, and rather may be attributed to perceived informational advantage, flight to familiarity, and some endogenous factors of hedge fund locality.

abstract: Recent research finds that there is significant variation in stock market participation by state and suggests that there might be state-specific factors that determine household stock market participation in the United States. Using household survey data, I examine how accounting quality of public companies at the state level affects households’ stock market participation decisions. I find that households residing in states where local public companies have better accounting quality are more likely to invest in stocks. Moreover, those households invest greater amounts of their wealth in the stock market. Cross-sectional tests find that the effect of accounting quality on stock market participation is more pronounced for less affluent and less educated households, consistent with prior findings that lacking familiarity with and trust in the stock market is an important factor deterring those types of households from stock investments. In state-level tests, I find that these household outcomes affect income inequality, which is less severe in states where high public-firm accounting quality spurs more stock market participation by poorer households. Conversely, in states where public firms have lower accounting quality, stock market participation among poorer households is less common, and a larger share of high equity returns accrues to richer households, exacerbating income inequality. / Dissertation/Thesis / Doctoral Dissertation Accountancy 2020

I examine how political geography affects firms' cost of debt. Policy risk, measured by proximity to political power reflected in firms' position in the country's political map, is negatively related to corporate bond ratings and positively related to firms' cost of debt. I find firms' policy risk can be mitigated by engaging in corporate political strategies like making campaign contributions or lobbying. Consistent with the view that such political strategies effectively protect firms against uncertainty about future policies, I find policy risk has less of an impact on the cost of debt of firms that support more powerful and well-connected politicians in the legislative co-sponsorship network or that spend more money on lobbying. Using a sample of state pension funds' equity holdings, I find that state pension funds exhibit not only local bias but also bias towards politically connected stocks. These politically connected local firms held by state pension funds do not exhibit better performance compared with their local benchmarks not held by these funds before the holding period, and the overweighting of politically connected local firms is negatively related to pension fund returns. My results do not support the information advantage hypothesis that state pension funds exhibit overweighting of local firms because they have an information advantage about home-state firms. I further examine the factors that explain local bias from political perspectives. My results show that local bias is related to public policy integrity and local politicians' congressional connections.

One of the main tenets of finance is diversification. Investors choose their portfolios so as to diversify away their idiosyncratic risk. In four essays included into this dissertation the implications of less than perfect diversification on investors’ performance and asset pricing are investigated. In Essay I we examine one particular instance in which diversification may play a role in a non-portfolio type of investment: the IPO. In an IPO, a set of potentially non-diversified investors – the existing shareholders – reduce their holdings of a company, listing the company and selling part of its shares. Our contribution is to show how portfolio diversification of controlling investors in private companies affects the IPO process. We demonstrate that companies sold by more diversified shareholders are less likely to be taken public, but when doing so they are priced more favourably. In Essays II and III we investigate the impact of incomplete diversification and imperfect risk-sharing on asset returns. Our argument is that the smaller shareholder base a firm has, the larger the fraction of company idiosyncratic risk on average its investors have to carry, and the higher return they would demand for that. We demonstrate that there is a negative and significant relationship between companies’ shareholder base and stock returns as well as between changes in shareholder base and stock returns. This effect is more pronounced for younger companies, but remains significant for seasoned companies as well. Applying our analysis to corporate events we demonstrate that abnormal performance following the repurchase can be partially explained by the reduction in the shareholders base resulting from repurchase. In Essay IV I investigate the motives behind one of the most puzzling examples of investors’ underdiversification – the local bias. Contrary to the predictions of classical financial theories, investors on aggregate overweight stock of proximate companies in their portfolios. I demonstrate that being placed in new community, individual investors not only soon become biased towards companies with establishments in this new locality, but they also obtain superior returns from these investments. Investing into the local stocks, therefore, is to a large degree rational. / Diss. Stockholm : Handelshögskolan, 2005 S. ii-vi: sammanfattning, s. 1-134: 4 uppsatser
