M.Com. (Finance and Investment Management) / The latest financial crisis that began in 2007 in the USA and spread to Europe, Africa and other continents has highlighted the importance of liquidity and its role in financial markets. One of the most commonly accepted mathematical models used in financial markets is the Black and Scholes option pricing model (BSM model). The assumptions in the BSM model have again been questioned during the current crisis and, in particular, the assumption of an unending risk-free supply of liquidity. This report reviews this assumption in the South African financial markets with local market participants. These views are polled through the use of a questionnaire to gauge these participants' views on liquidity using proxies or factors that impact overall liquidity. The results showed significantly different perspectives depending on the role of the participant as either market maker or price taker. The overall liquidity proxies used showed that local market participants believe these proxies impact liquidity. The view that liquidity is an unending commodity and thus priced as riskless was disputed by local market participants. The practical significance of the research problem in the local context should provide local participants with some insight into local perceptions on liquidity that may provide some practical tools when pricing or trading instruments in the local market.

Exchange traded funds (ETFs) have increased significantly in popularity since they were first introduced in 1993. However, there is still much that is unknown about ETFs in the extant literature. This dissertation attempts to fill gaps in the ETF literature by using three related essays. In these three essays, we compare ETFs to closed ended mutual funds (CEFs) by decomposing the bid-ask spread into its three components; we look at the intraday shape of ETFs and compare it to the intraday shape of equities as well as examine the co-integration factor between ETFs on the London Stock Exchange and the New York Stock Exchange; we also examine the differences between leveraged ETFs and unleveraged ETFs by analyzing the impact of liquidity and volatility. These three essays are presented in Chapters 1, 2, and 3, respectively. Chapter one uses the Huang and Stoll (1997) model to decompose the bid-ask spread in CEFs and ETFs for two distinct periods—a normal and a volatile period. We show a higher adverse selection component for CEFs than for ETFs without regard to volatility. However, both ETFs and CEFs increased in magnitude of the adverse selection component in the period of high volatility. Chapter two uses a mix of the Werner and Kleidon (1993) and the Hupperets and Menkveld (2002) methods to get the intraday shape of ETFs and analyze co-integration between London and New York trading. We find two different shapes for New York and London ETFs. There also appears to be evidence of co-integration in the overlapping two-hour trading period but not over the entire trading day for the two locations. The third chapter discusses the new class of ETFs called leveraged ETFs. We examine the liquidity and depth differences between unleveraged and leveraged ETFs at the aggregate level and when the leveraged ETFs are classified by the leveraged multiples of -3, -2, -1, 2, and 3, both for a normal and a volatile period. We find distinct differences between leveraged and unleveraged ETFs at the aggregate level, with leveraged ETFs having larger spreads than unleveraged ETFs. Furthermore, while both leveraged and unleveraged ETFs have larger spreads in high volatility, for the leveraged ETFs the change in magnitude is significantly larger than for the unleveraged ETFs. Among the multiples, the -2 leveraged ETF is the most pronounced in its liquidity characteristics, more so in volatile times.

Cette thèse analyse les conséquences de l’intégration d’un milieu bancaire conventionnel pour une banque islamique. Elle est composée de trois chapitres. Un premier traité de la conformité Sharia des banques islamiques. Cette conformité est assurée par un comité de supervision éthique. Nous détaillons le rôle et les tâches de ce comité de supervision éthique et montrons comment les contraintes réglementaires internationales ainsi que la pénurie éventuelle de personnels compétents pour alimenter ces sharia boards incitent la banque islamique à externaliser ce contrôle de conformité Sharia. En se proposant sur modèle théorique inspiré de Kornai, Maskin and Roland (2003), ce premier chapitre examine ainsi l'impact de l'externalisation de ce comité sur le business model de la banque islamique. Le deuxième chapitre est essentiellement empirique : nous comparons l'efficacité des deux modèles de banque, l’un internalisant (l’autre externalisant) le processus d’examen/ validation de la conformité Sharia. Pour procéder à cette étude empirique, nous examinons un échantillon d'une centaine de banques qui se divise en deux groupes de banques un premier qui externalise le contrôle de conformité Sharia et le deuxième l'internalise. Nous montrons que les banques sont plus efficaces lorsqu'elles externalisent ce processus de conformité. Finalement, un troisième chapitre traite la question de la création de liquidité au sein des deux banques, conventionnelle et islamique. Dans ce chapitre nous développons un modèle théorique inspiré de Diamond (2007) et nous comparons la création de liquidité de ces deux banques. Nous mettons en évidences les contraintes qui pèsent sur la banque islamique, elles se manifestent dans la structure du bilan des banques islamiques, un bilan qui présente un volume important d'actifs tangibles. On montre que la structure de ce bilan limite la possibilité pour les banques islamiques de concurrencer les banques conventionnelles et ainsi remet en cause leur capacité à intégrer un milieu bancaire conventionnel. / This dissertation analyses the consequences of the integration of an Islamic bank into a conventional banking environment. The dissertation is composed of three chapters. The first examines the Islamic banks' compliance, which is ensured by a supervisory ethical committee. We examine the role and the tasks of this committee in detail, showing how international regulatory constraints, as well as a general lack of individuals with the required skills to sit on the Sharia boards, provide incentives for the Islamic bank to outsource the monitoring of Sharia compliance. Basing our study on a theoretical model, inspired by Kornai, Maskin and Roland (2003), this first chapter analyses how the outsourcing of this committee has an impact on the business model of the Islamic bank. The second chapter is largely empirical; we compare the effectiveness of two bank models, one in which the Sharia compliance validation process is internal, and one in which it is external. To test this empirical study, we analyze a sample of around 100 banks which are divided into two groups, one which outsources the Sharia compliance and monitoring and one which internalizes this process. We show that banks are more effective when they outsource the compliance monitoring process. Finally, the third chapter approaches the question of liquidity creation within two types of bank: Islamic and conventional. In this chapter, we develop a theoretical model inspired by Diamond (2007) and we compare the liquidity creation process in these two banks. We demonstrate the constraints that burden the Islamic bank, shown by the high volume of tangible assets in their balance sheets. We demonstrate that the structure of this balance sheet limits the possibilities for Islamic banks to compete with conventional banks, and thus brings into question their capacity to integrate a conventional banking environment.

This paper focuses on policies and regulations on open economies to achieve financial stability and social welfare. In the first chapter, I develop a dynamic model to study optimal liquidity regulations for multiple assets with differing levels of liquidity. I show that optimal macroprudential policies are affected by both asset liquidity and the multi-asset structure. Lower asset liquidity amplifies drops in asset prices and tightens the collateral constraint during financial crises, thus raising macroprudential taxes to discourage holding. With multiple assets, the marginal benefit of investing in one asset is affected by the future cross-price elasticities of all assets. Quantitatively, optimal macroprudential policies increases welfare by introducing a portfolio with more liquid assets and less borrowing. However, the Basel III reform deteriorates welfare, as agents overaccumulate liquid assets. In the next chapter, I focuses on the welfare analysis of currency depreciation through endogenous R&D where the economy faces a trade-off between the gain from export and disinvestment of technology. I show that real depreciation decreases welfare when productivity is endogenous, as the long-term bust due to sluggish productivity dominates the short-term boom in consumption and output. In the final chapter, I study the optimal monetary policy in this framework. The optimal policy is a targeting rule of inflation, output gap, and the terms of trade, considering the trade-off between the international purchasing power and the cost of importing R&D. The variation of the optimal monetary policy is larger than the standard Taylor rule and the optimal monetary policy under exogenous productivity.

El presente estudio analiza cuál es el impacto que tienen los requerimientos de encaje en los créditos bancarios destinados a actividades productivas. Se tiene en consideración la particularidad del sistema financiero peruano, que se caracteriza por poseer un alto nivel de dolarización y concentración. Por ello, se busca determinar cómo interactúan los requerimientos de encaje por moneda y ciertas características de cada banco, tales como la liquidez, el tamaño del banco y la rentabilidad, ante cambios en el instrumento de política. Luego de aplicar un modelo de paneles dinámicos diferenciando por moneda se encontró la presencia de heterogeneidad en las respuestas de los bancos. Los principales resultados demostraron que los bancos más grandes y con mayor liquidez mitigan mejor los cambios del encaje en moneda extranjera en los créditos en la misma moneda. De igual manera, los bancos más líquidos y rentables son menos sensibles ante cambios en el encaje en moneda nacional. / This study analyzes the impact of reserve requirements on banking credit for productive activities. It takes into account the particularity of the Peruvian financial system, which is characterized by having a high level of dollarization and concentration. Therefore, it seeks to determine how the reserve requirements by currency and certain characteristics of banks interact with each other, such as liquidity, bank size and profitability, to change in the policy instrument. After applying a dynamic panel model differentiating by currency, the presence of heterogeneity in bank’s responses was found. The main results demonstrated that largest and most liquid banks better mitigate the changes in the reserve requirement in foreign currency in credits in the same currency. Similarly, the most liquid and profitable banks are less sensitive to changes in reserve requirement in national currency. / Trabajo de investigación

This study investigated the impact of the levels of liquidity of Initial Public Offering (IPO) stocks on the long-run performance of IPOs over a five year period. In addition the study sought to investigate if the levels of liquidity of IPO stock were significantly higher than non-IPO stock. The methodology used was the calendar time portfolio approach based on the Fama-French regression equation. The study found that over a five year period IPOs did not underperform or over-perform the market. In addition the study found that the liquidity levels of IPOs were not significantly higher than non-IPOs. While the lower liquidity levels help explain the fact that the IPOs did not underperform the market, they do not indicate the existence of a liquidity risk premium on the Johannesburg Stock Exchange (JSE). / Dissertation (MBA)--University of Pretoria, 2011. / Gordon Institute of Business Science (GIBS) / unrestricted
