The effects of mean reversion on dynamic corporate finance and asset pricingChu, Kai-cheung., 朱啟祥. January 2012 (has links)
This thesis aims to investigate the effects of mean reversion on dynamic corporate finance decisions and stock pricing.
In Chapter 1, a continuous-time real option model of mature firm that produces product with exogenous mean reverting price is developed to study the firm’s optimal exit and leverage policies. Simulation results show that both liquidation and bankruptcy triggers are negatively related to the long run price levels, while the speed of mean reversion interacts with the long run price level to affect the firm’s exit decisions in two opposite directions depending on the level’s relative magnitude to total operating expenses (the firm’s instantaneous operation costs plus coupon payments). Regarding the leverage policy, apart from showing the static tradeoff result that firm uses more debts when the current revenues are high, the model exhibits at high long run price levels low-debt scenarios that are analogous to the pecking order prediction, suggesting that both static tradeoff and pecking order effects coexist under a mean reversion environment. Because equity values increase more vigorously with prices than debt values do, the tradeoff effect is overwhelmed and the resulting optimal leverage ratios are generally decreasing with the current price levels.
Chapter 2 extends the model in Chapter 1 to derive the closed-form expression of the firm’s equity beta. Because expected stock returns are linearly related to the equity beta by model assumption, several implications to the cross-sectional behaviors of stock returns are obtained. First, it is predicted that firms with mean reverting characteristics should earn lower average returns than others without. The model further reveals the coexistence of positive book-to-market and leverage premiums to stock returns. Most importantly, due to the possession of bankruptcy option by equity holders, high distress risk stocks are expected to earn lower average returns than otherwise similar but low distress risk stocks. This provides an extra dimension to study the ‘distress premium puzzle’. Finally to verify the model predictions, empirical tests using historical market and accounting data from CRSP and COMPUSTAT are conducted, and supportive results are generally obtained. / published_or_final_version / Economics and Finance / Doctoral / Doctor of Philosophy

Essays on international asset pricing under segmentation and PPP deviationsChaieb, Ines. January 2006 (has links)
This dissertation comprises two essays. The first essay develops and tests a theoretical model that provides new insights when markets are partially segmented and the purchasing power parity (PPP) is violated which seems to be the case for the majority of national markets. The theoretical part derives closed form solutions for asset prices and portfolio holdings. Particularly, we show that deviations from PPP in mildly segmented markets induce a new form of systematic risk, termed segflation risk, and in equilibrium investors require compensation for this risk. A strong feature of the model is that it provides a theoretical framework for testing important issues; such as, pricing of foreign exchange risk and world market structure. The model also nests several existing international asset pricing models and thus provides a framework to distinguish empirically between competing models. The empirical part of the essay provides an empirical validation of the model for eight major emerging markets. The results give support to the model and point to the importance of the segflation risk which is statistically and economically significant. / The second essay uses our theoretical model to address the question of whether the IFC investable indices are priced globally or locally. Indeed S&P/IFC provides two emerging market indices: the IFC global index (IFCG) and its subset the IFC investable index (IFCI). Since the IFCI is fully investable, both the academic and practitioners implicitly assume that this subset of emerging markets is priced in the global context. This is a critical assumption for corporate finance decisions and portfolio management. Hence, this essay investigates the pricing behavior of the IFCI index returns using a conditional version of our model that allows for segmentation and PPP deviations. The results suggest that local factors are important in explaining returns of the IFC investable indices and that the return behavior of IFCI indices is similar to that of the IFCG.

The applicability of the risk-free rate proxy in South Africa : a zero-beta approach.Charteris, Ailie. January 2009 (has links)
Thesis (M.Comm.)-University of KwaZulu-Natal, Pietermaritzburg, 2009. / The Capital Asset Pricing Model (CAPM), despite criticism and debate regarding its validity, remains the most widely employed model to estimate the cost of equity for use in capital budgeting decisions, both in the U.S. and in South Africa. The risk-free rate specified in the model is generally estimated with the use of a government security, but there is some concern as to the appropriateness of this practice in the South African market. An alternative approach was derived by Black (1972), known as the minimum-variance zero-beta portfolio returns; but the suitability of this parameter in the South African market has not yet been examined.
The objective of this study therefore is to determine the best method to estimate the risk-free rate for applications of the CAPM in South Africa. A set of theoretical requirements that an asset must closely satisfy to be considered a suitable proxy for the risk-free rate are derived, with the most commonly employed proxies being compared to these criteria to ascertain their appropriateness. The zero-beta portfolio returns are computed, in conjunction with the rate that investors have historically viewed as the minimum required return, denoted by the intercept of the CAPM. Hypothesis tests of the equality of the two estimates of the risk-free rate and the minimum required return are conducted, as well as a comparison of the forecasting accuracy of the model using the different risk-free rate values.
The results of the analysis indicate that the South African proxies diverge substantially from the criteria, and are likely to overstate the true-risk-free rate. In complete contrast to this, the hypothesis tests reveal that the proxies understate the intercept estimate, whilst the zero-beta portfolio returns closely approximate this value. This finding that the zero-beta portfolio returns, which are larger than the proxy yields, are more suitable appears counter-intuitive given the goal to identify the minimum return from investing. This result can possibly be explained by the fact that the CAPM intercept represents the average of the riskless lending and borrowing rates, whilst the proxy only denotes the former. The borrowing rate is likely to be higher than the lending rate; thus giving reason for the average being greater. However, the possibility also remains that the results observed may be a consequence of the incorrect specification of the market portfolio, that the tests employed are inapt, or that the model itself is inappropriate.
The forecasting analysis confirms the greater accuracy associated with employing the zero-beta portfolio returns as the risk-free rate compared to the use of a proxy, but the improvement is small. Thus the choice for the practitioner is whether the increase in accuracy is justified by the difficulty and time involved with estimating the zero-beta portfolio returns.

The international capital asset pricing model : empirical evidence for South Africa.Peerbhai, Faeezah. January 2011 (has links)
An integral component of all corporations‘ financial operations is the determination of the cost of equity of the firm. This input is required in many financial decision making processes, and the correct estimation of this value is therefore a very important issue. The Capital Asset Pricing Model (CAPM) of Sharpe (1964) and Lintner (1965) has filled this gap since its inception, and has been extensively used by both corporations and individuals in their estimation of expected return. Whilst the standard form of this model is intuitive and simple in its implementation, an additional issue faced when utilising it in the current day is that of global financial integration. Whilst the CAPM is suitable for use in a market which is completely segmented from the rest of the world, this is often not the case as the barriers across countries have gradually declined, with the result that much of the world is now internationally integrated.
This therefore led to two extensions of the CAPM to the international environment by both Solnik (1974) and Grauer, Litzenberger and Stehle (1976). Whilst both are referred to as International CAPM (ICAPM) models, the difference lies in that Solnik‘s (1974) model incorporates the presence of exchange rate risk, whilst the Grauer, Litzenberger and Stehle (1976) one does not. This study therefore provides an analysis of the suitability of these two models to the South African environment, along with a comparison of the relative performances of each model against that of the standard CAPM model. The three different methods of analysis used are: the unconditional approach, a conditional GARCH approach, as well as the cost of equity approach. The analyses are applied to the data which consists of all listed firms on the JSE from 1990 up to 2010, with multiple methods of evaluation employed, such as information criteria and forecasting, in order to provide a robust analysis of all three models.
The results of the analysis vary across the different methods used, however since a significant amount of evidence was found of the International CAPM models, it can be concluded that an international asset pricing model should be used instead of a domestic one. In the choice between the single-factor ICAPM model and the multifactor ICAPMEX, even though use of the Grauer et al (1976) model would not be inappropriate, it was concluded that use of Solnik‘s (1974) ICAPMEX model would be the best suited to the South African financial environment, as the presence of exchange rate risk factors in an asset pricing model is found to be an important inclusion which may lead to better cost of equity estimates. / Theses (M.Com.)-University of KwaZulu-Natal, Pietermaritzburg, 2011.
