This dissertation presents five research essays evaluating the performance of managed funds in light of the investment strategy and manager characteristics exhibited by institutional investment companies. An analysis of investment performance with respect to a fund managers strategy provides important information in determining whether performance objectives have been achieved. There are a number of different types of investment strategies managed funds may adopt. However, the primary dichotomy is on the basis of whether the portfolio manager implements either an active or index approach. Active managers attempt to outperform the market through the use of price-sensitive information, whereas a passive manager's objective is to replicate the returns and risk of a target benchmark index. The evaluation of investment manager characteristics is also evaluated. This is motivated on the basis that asset management entities place significant emphasis on both the articulation and differentiation of their investment style relative to competitors, and selling the strengths of their portfolio management skills (in terms of past performance) as well identifying the key individuals comprising their investment team and their unique attributes. For active equity managers, the methods used in constructing portfolios and implementing the investment strategy include security selection, in terms of 'top-down' or 'bottom-up' strategies, value-biased, growth-biased or style-neutral strategies, and portfolios exhibiting market capitalisation biases (i.e. preferences to large or small-cap securities). In terms of active bond portfolio management, the most common strategies include duration management and yield curve positioning. Active managers' strategies are likely to extend beyond stock selection, in particular, where the fund manager adjusts the portfolio's composition in anticipation of favourably capitalising on future movements in the market. For index managers, replication of both the returns and risk of the underlying index may be achieved through either full-replication of constituent stocks comprising the index, or through non-replication techniques (stratified sampling and/or optimisation). Each essay provides a unique contribution to the literature with respect to the performance of active and index funds, as well as an analysis of funds that invest specifically in domestic equities, domestic fixed interest, and diversified funds that invest across the broad spectrum of asset classes. The origins of the performance evaluation literature are ascribed to Cowles' (1933) pioneering work, and the literature has given increasing attention to the topic. However the most fundamental issue considered in almost all previous studies of managed fund performance is the extent to which actively managed portfolios have earned superior risk-adjusted excess returns for investors. The literature has overwhelmingly documented (with a small number of exceptions) that active funds have been unable to earn superior returns, either before or after expenses (e.g. Jensen (1968), Elton et al. (1993), Malkiel (1995), Gruber (1996)). While the international evidence is supported by the few Australian managed fund studies available, Australian research remains surprisingly scarce. This is perplexing considering the sheer size of the investment industry in Australia (around $A717 billion as at 30 June 2001) and the importance placed on the sector with respect to successive Federal Governments' retirement income policies. The objectives of this dissertation therefore involve an analysis of managed fund performance with respect to differences in investment strategies (i.e. active and index), as well as providing an analysis of funds invested in equities, bonds and diversified asset classes (or multi-sector portfolios). The first essay evaluates the market timing and security selection capabilities of Australian pooled superannuation funds. These funds provide institutional investors with exposure to securities across many different asset classes, including domestic and international equities, domestic and international fixed interest, property and cash. Surprisingly, the specific analysis of multi-sector funds is scarce in the literature and limited to Brinson et al. (1986, 1991), Sinclair (1990), and Blake et al. (1999). This essay also evaluates performance for the three largest asset classes within diversified superannuation funds and their contribution to overall portfolio return. The importance of an accurately specified market portfolio proxy in the measurement of investment performance is demonstrated, where the essay employs performance benchmarks that account for the multi-sector investment decisions of active investment managers in a manner that is consistent with their unique investment strategy. This approach rectifies Sinclair's (1990) analysis resulting from benchmark misspecification. Consistent with the literature, the empirical results indicate that Australian pooled superannuation funds do not exhibit significantly positive security selection or market timing skill. Given the evidence in the literature surrounding the inability of active funds to deliver superior returns to investors, lower cost index funds have become increasingly popular as an alternative investment strategy. Despite the significant growth in index funds since 1976, when the first index mutual fund was launched in the U.S., research on their performance is sparse in the U.S. and non-existent in Australia. The second essay provides an original analysis of the Australian index fund market, with specific analysis applicable to institutional Australian equity index funds offered by fund managers. While indexing is theoretically straightforward, in practice there exist potential difficulties in exactly matching the return of the underlying index. Therefore the magnitude of tracking error is likely to be of concern to investors. This essay documents the existence of significant tracking error for Australian index funds, where the magnitude of the difference between index fund returns and index returns averages between 7.4 and 22.3 basis points per month for funds operating at least five years. However, there is little evidence of bias in tracking error, implying that these funds neither systematically outperform or underperform their benchmark on a before cost basis. Further analysis documents that the magnitude of tracking error is related to fund cash flows, market volatility, transaction costs and index replication strategies used by passive investment managers. The third essay presents evidence of the performance of U.S. mutual funds, where attention is given to both active and index mutual funds for which the applicable benchmark index is the S&P 500. This essay examines both the magnitude and variation of tracking error over time for S&P 500 index mutual funds. The essay documents seasonality in S&P 500 index mutual fund tracking error, where tracking error is significantly higher in the months of January and May, together with a seasonal trough in the quarters ending March-June-September-December. Statistical evidence indicates tracking error is both positively and significantly correlated with the dividend payments arising from constituent S&P 500 securities. In terms of a performance comparison between actively managed and index funds, active funds on average are found to significantly underperform passive benchmarks. On the other hand, S&P 500 index mutual funds earned higher risk-adjusted excess returns after expenses than large capitalisation-oriented active mutual funds in the period examined. These results suggest the S&P 500 is consistent with capital market efficiency, implying an absence of economic benefit accruing to the average investor utilising actively managed U.S. equity mutual funds. The fourth essay presented in the dissertation examines the performance of Australian investment management organisations with direct reference to their specific characteristics and strategies employed. Using a unique information source, performance is evaluated for actively managed institutional balanced funds (or diversified asset class funds), Australian share funds and Australian bond funds. Performance is evaluated with respect to the investment strategy adopted, the experience and qualifications held by investment professionals, and the tenure of the key investment professionals. This essay also evaluates the performance of senior sector heads to determine the skills of individuals driving the investment process, even though these individuals may migrate to competitor organisations. The essay finds evidence that a significant number of active Australian equity managers earned superior risk-adjusted returns in the period, however active managers perform in line with market indices for balanced funds and Australian bond funds. A number of manager characteristics are also found to predict risk-adjusted excess returns, systematic risk and investment expenses. Of particular note, performance of balanced funds is negatively related to the institution's age and the loyalty of non-senior investment staff. Performance is also found to be significantly higher for managers that predominantly operate their portfolios using a bottom-up, stock selection approach. Interestingly, the human capital of managers, measured as the years of tertiary education undertaken, does not explain risk-adjusted excess returns. Systematic risk is positively related to an institutions age and negatively related to both senior manager loyalty and the implementation of bottom-up portfolio management strategies. In terms of management expenses, fees are directly related to the Australian equities benchmark allocation, the years of tertiary education, the number of years service (loyalty) for non-senior investment professionals and the total years experience of senior money managers. This concluding essay also documents that changes in top management have significant performance effects. In the 12-month period after a change in fixed income director or chief investment officer, performance is significantly lower and significantly higher, respectively. There is no significant difference in performance where changes in top management occur for Australian equities. The years of service (loyalty) provided to asset management firms by equities directors is inversely related to risk-adjusted return. The fifth and final essay examines the investment performance of active Australian bond funds and the impact of investor fund flows on portfolio returns. This essay represents a significant and original analysis in terms of its contribution to the literature, given the absence of Australian bond fund performance analytics and also the limited attention provided in the U.S. Both security selection and market timing performance is evaluated using both unconditional models and conditional performance evaluation techniques, which account for public information and the time-variation in risk. Overall, the results of this essay are consistent with the U.S. and international mutual fund evidence, where performance is found to be consistent with an efficient market. While actively managed institutional funds perform broadly in line with the index before expenses, the paper documents significant underperformance for actively managed retail bond funds after fees. The study also documents that retail fund flows negatively impact on market timing coefficients when flow is not accounted for in unconditional models.

Accompanied by the enormous losses cause by the worldwide economic recession and Internet bubbles, venture capital industry at the same time is faced with another crucial problems: for a venture capital firm, what characteristics should a venture capitalist possess? How does these characteristics influence the behaviors of the venture capital firms and venture capitalists themselves? As everyone knows, venture capital firms differ significantly in business strategies and fund sources, thereby give rise to the difference of venture capital firms in selecting the characteristics of venture capitalists. Therefore, universal traits and characteristics of venture capitalists are difficult to find out. In the circumstances, venture capital firms must understand how venture capitalists characteristics may influence investment behaviors and strategies. By means of the analysis of the characteristics of venture capitalists and venture capital firms, this study tries to find out the important factors affecting the behaviors of venture capitalists. Through the empirical research towards the Taiwan venture capitalists, several findings are presented in this study. As finding shows, some characteristics of venture capital firms such as firm age have a great influence on the behaviors of venture capitalists. Moreover, from the insignificance of some factors examined in this study, we conclude that there are still some structural factors influencing the behaviors of venture capitalists.

In two unrelated papers, we examine different aspects of mutual fund performance and other issues. In the first chapter, we look at exchange-traded funds (ETFs) and how they differ from index funds in performance and tracking error. Using daily data and a more comprehensive sample than past research, we find abnormal returns associated with the ETFs are higher than the alphas of the index funds in most cases. The results are much more prevalent in funds that follow the S&P 500 than funds that do not. When examining the tracking errors, we find index funds are able to track their indexes much better than ETFs and domestic ETFs are better than ETFs that track international indexes. In our most significant finding, we find that tracking error affects fund flow in the following period. While fund flows are generally increasing for both ETFs and index funds, funds that track their respective index better increase their net assets by a larger percentage than funds that track their index less well. In the second chapter, we look at the differences in performance and characteristics of mutual funds as they relate to the manager's gender. Using a larger sample and different techniques than have been used in the past, we find some differences in our matched comparison which suggest female managers have a lower risk tolerance than males. Females also tend to hold a higher number of assets (stocks) and fewer assets in their top 10 holdings than do male managers. In, pooled regressions, we find weak, but significant evidence that current female fund managers, when analyzed as a group, show slightly lower performance than male managers. We then analyze performance within funds over time. Our most consistent result is that when changing the composition of fund management, regardless of gender, the new management has significantly greater performance than prior management. We also find some evidence, although not conclusive, that the percentage of female managers managing a fund is negatively related to the fund's performance over time. Finally, we find the determinants of abnormal returns cannot be attributed to the fund manager's gender.

Den kvalitativa studiens syfte var att undersöka ledarskapets betydelse för arbetsmotivationen. Tio semistrukturerade intervjuer genomfördes. Dessa analyserades genom en induktiv tematisk analys som resulterade i fyra huvudteman. Arbetets motivationsfaktorer, med de tillhörande underteman syftet med arbetet, frihet, utveckling och utmaning, samt lönens betydelse. Organisationsledarskap, handlade om att ha insyn och riktning, samt styrning. Chefsegenskaper beskrevs utifrån två underteman närvaro och stöd, samt tillit. Motiverande arbetsbeteende om medarbetares identifikation med organisationen. Resultaten går i linje med tidigare forskning och visar sammantaget att olika ledarskapsbeteenden upplevs influera medarbetarnas arbetsmotivation. Inre- och yttre motivationsfaktorer, samt olika ledarskapsegenskaper upplevdes också vara en väsentlig del av arbetsmotivationen. / The purpose of the qualitative study was to examine the importance of leadership for work-motivation. Ten semi-structured interviews were conducted. These were analyzed through an inductive thematic analysis which resulted in four main themes. The factors of work motivation, resulted in four sub-themes, the purpose of the work, freedom, development and challenges, as well as the meaning of the salary. Organizational leadership was about having insight, direction and steering. The manager characteristics was described on the basis of two sub-themes which were presence and support, as well as trust. Motivating work behavior and identification with the organization. The results are in line with the previous research and together showed that different leadership behaviors can influence work-motivation. Internal- and external motivation, and various leadership qualities, were also perceived to be an essential part of work-motivation.

Die vorliegende Dissertation ist in drei Themenblöcke unterteilt. Im Mittelpunkt des ersten Themenblocks steht die vergleichende Analyse der Fondsregulierung in den USA und Deutschland/der EU in Bezug auf Derivate und Verschuldung vor, während und nach der Finanzkrise 2007-2009. Ziel ist es, anhand der Darstellung der geltenden Regulierung und ihrer Anwendbarkeit auf die hypothetische Nutzung von Credit Default Swaps (CDS) durch Anleihefonds, aufzuzeigen, wie viel Flexibilität Fonds in beiden Ländern haben. Insgesamt ist der aus der Fondsregulierung erwachsende Spielraum im Hinblick auf den Einsatz von Derivaten und Verschuldung für Fonds in beiden Ländern hoch, so dass Fonds unbeobachtet ihre Zusammensetzung in Richtung risikoreicherer Kapitalanlagen lenken könnten. Der zweite Themenblock beschäftigt sich empirisch mit der Frage, in wie weit Fonds ihre Flexibilität tatsächlich ausnutzen. Als Erstes wird dabei untersucht, wie hoch das Verlustpotential der größten Fonds in den USA und Deutschland aus CDS ist. Ferner wird analysiert, ob Fondskommentare in Jahres- und Halbjahresberichten bezogen auf deren Nutzung von CDS mit den tatsächlichen CDS-Beständen konsistent sind. Basierend auf den Resultaten ist es zu empfehlen, nicht nur bestehende Regeln im Hinblick auf die spekulative Anwendung von Derivaten angemessen zu verschärfen, sondern auch die Publizitätspflichten in beiden Ländern weiter zu standardisieren. Unter Heranziehung umfangreicher Fondscharakteristika, insbesondere Managercharakteristika, untersucht der dritte Themenblock, was die Entscheidung der US Anleihefonds CDS zu benutzen, deren Nutzung zu erweitern sowie die Nutzungsweise beeinflusst. Ferner werden die exakten Typen von CDS, die von Anleihefonds gehalten werden, wie z. B. long oder short CDS, die sich auf Einzelnamen oder Gruppen von Titeln beziehen, aufgezeigt. / The thesis consists of three parts. The first part analyzes the regulation at the time surrounding the 2007-2009 financial crisis and after with respect to leverage and derivative holdings for mutual funds in the U.S. and Germany/the EU. After presenting a detailed overview of U.S. and German/European regulations, this study thoroughly compares the levels of flexibility funds have in both countries. All analyses reveal that under existing derivative and leverage regulation, funds in both countries are able to increase risk by using derivatives up to the point at which it is possible for them to default solely due to investments in derivatives. This makes the issue of regulation highly relevant for the public and regulators. The second part builds upon the first and empirically investigates the level of credit derivatives use by funds together with their communication toward investors. Firstly, the loss potential arising from investments into CDS for a sample of large U.S. and German mutual funds is analyzed. Secondly, it is investigated whether comments on CDS use contained in periodic fund reports are consistent with the disclosed CDS holdings. Based on the results, it seems advisable that regulators in both countries tighten rules restricting the speculative use of derivatives by funds to a reasonable level, as well as implement more standardized disclosure policies. The third part analyzes what determines whether U.S. corporate bond funds decide to use CDS in a particular period between mid-2004 to 2010, to which extent they use them and how, by relying on various fund characteristics including an extended set of manager variables. In addition, the types of various credit derivatives that funds use (e.g. long and short CDS on single-name or multi-name underlying positions) are presented. The results suggest that the characteristics of fund managers affect a fund’s risk taking via derivatives, in addition to fund fundamentals.

Diese Dissertation besteht aus drei Essays, welche empirisch den Einfluss von Manager-Optimismus auf verschiedene unternehmenspolitische Entscheidungen untersuchen. Der Ausdruck Manager-Optimismus wird hierbei verwendet um Agenten (Manager) zu beschreiben, die im Interesse der Prinzipale (Aktionäre) zu handeln glauben, aber tatsächlich ins Positive verzerrte Vorstellungen über ihre eigenen Fähigkeiten und somit über die zukünftige Performance ihrer Firmen haben. Das erste Papier untersucht den Einfluss von Manager-Optimismus auf Ausstattungsmerkmale von Fremdkapitalverträgen. Konsistent mit nach oben verzerrten Erwartungen über die zukünftigen Cash Flows ihrer Firmen zeigt sich, dass Firmen mit übermäßig optimistischen Managern häufiger Performance abhängige Verträge nutzen und zugleich eine schlechtere Performance nach Aufnahme des Fremdkapitals aufweisen als solche mit rationalen Managern. Der zweite Artikel untersucht unternehmerisches Risikomanagement. Es stellt sich heraus, dass Firmen mit optimistischen Managern signifikant weniger wahrscheinlich Finanzderivate zur Absicherung ihrer Fremdwährungsrisiken nutzen als solche mit rationalen Managern. Dieses Verhalten ist mit einer Unterschätzung von Insolvenzkosten bzw. Kosten einer finanziellen Notlage konsistent. Der dritte Teil der Arbeit untersucht empirisch das Verhältnis zwischen Manager-Optimismus und der Nutzung von großen Abschreibungen im Rahmen von CEO-Wechseln. Nach dem Abgang von CEOs kann man häufig beobachten, dass deren Nachfolger ein so genanntes big bath accounting durchführen. Hierbei werden durch Abschreibungen Verluste dem Vorgänger zugeschrieben und Verdienste für zukünftige Performanceverbesserungen für sich beansprucht. In Übereinstimmung mit den verzerrten Erwartungen über zukünftige Cash Flows ihrer Firmen zeigt sich, dass Unternehmen, welche einen optimistischen Manager einstellen, weniger wahrscheinlich ein solches earnings bath durchführen, als Firmen, die rationale Manager einstellen. / This thesis consists of three essays that empirically investigate to what extent managerial optimism affects corporate financial policy decisions. The term managerial optimism is used to describe agents (managers), who believe to act in the principals’ (shareholders’) best interest but in fact have upwardly biased views about their own abilities and consequently about the performance of their firms. The first paper investigates the impact of managerial optimism on debt contract design. Consistent with their upwardly biased view on their firm’s future cash flow, we find that firms with overly optimistic managers are more likely to choose performance sensitive debt (PSD) contracts and show worse post issue performance than firms with rational managers. The second paper analyzes corporate risk management. We find that firms with overly optimistic managers are significantly less likely to use financial derivatives to hedge their currency exposures than those with rational managers. This behavior is consistent with an underestimation of bankruptcy or financial distress costs by overly optimistic managers. The third paper empirically tests the relationship between managerial optimism and the use of large write-offs following CEO turnover. Subsequent to CEO turnover, it is often observed that incoming CEOs engage in this so called big bath accounting. Losses incurred during the big bath are attributed to the predecessors and the incoming CEOs take credit for future performance improvements. Consistent with their upwardly biased expectations concerning future firm cash flow, we find that firms hiring optimistic managers are less likely to experience an earnings bath in the year of the turnover than those hiring their rational counterparts.
