Multi-scaling modelling in financial markets

In the recent years, a new wave of interest spurred the involvement of complexity in finance which might provide a guideline to understand the mechanism of financial markets, and researchers with different backgrounds have made increasing contributions introducing new techniques and methodologies. In this paper, Markov-switching multifractal models (MSM) are briefly reviewed and the multi-scaling properties of different financial data are analyzed by computing the scaling exponents by means of the generalized Hurst exponent H(q). In particular we have considered H(q) for price data, absolute returns and squared returns of different empirical financial time series. We have computed H(q) for the simulated data based on the MSM models with Binomial and Lognormal distributions of the volatility components. The results demonstrate the capacity of the multifractal (MF) models to capture the stylized facts in finance, and the ability of the generalized Hurst exponents approach to detect the scaling feature of financial time series.

Three essays on financial markets

This thesis examines stock price behaviour on the New York Stock Exchange.  The thesis develops modelsto show that firms on the stock exchange are different with respect to volatility and changes in calender dates.  Moreover, the thesis shows that firm returns are affected differently by oil prices.

Panel versus GARCH information in unit root testing with an application to financial markets

In a search for more powerful unit root tests, some researchers have recently proposed accounting for the information contained in the GARCH of the innovations. However, while promising, tests with GARCH are difficult to implement, which has made them quite uncommon in the empirical literature. A computationally attractive alternative is to account not for GARCH but the information contained in a panel of multiple time series. The purpose of the current note is to compare the relative power achievable from these two information sources. © 2014 Elsevier B.V.

Control of the Australian life insurance industry: an example of regulatory externalities within the Australian financial sector 1870-1945

The regulatory environment in which the Australian life insurance industry operates has its antecedents in two major periods of legislative intervention. The first established the principle of ‘freedom with disclosure’ in the 1870s, which has since formed the basis of the regulatory approach. In the 1940s, the second refined the concept in the context of a general recognition of an interventionist approach to financial markets. It is suggested that regulation of the life insurance market in Australia came about not in response to problems associated with market failure but in reaction to external influences not directly related to conditions in the Australian life insurance industry. This was impacted not only on the timing of intervention but on the approach taken as well.

Does organisational heritage matter in the development of offshore markets? the case of Australian life insurers

The globalization of financial markets over the past decade has focused the spotlight on the responsiveness of financial firms to international pressures. Insurance markets have traditionally relied on global networks not only to expand the insurers' sphere of influence but also to support domestic business. Until relatively recently, Australian insurance companies have not played a significant role in the development of international markets. However, in the last decade of the twentieth century Australian insurers ventured overseas on a scale without precedence. This article presents an historical perspective on the internationalization of the Australian life-insurance market with a view to understanding why these firms have been classified "late starters" in the internationalization stakes. In a broader capacity it provides insights into the impediments to overseas expansion and the forces encouraging or discouraging the development of cross border networks.

Equity market price interactions between China and the other markets within the Chinese states equity markets

This study examines the cointegrating and long-term causal relationships of equity market prices in equity markets of Chinese states namely, Shanghai, Shenzhen, Hong Kong, Taiwan and Singapore. I cover the period between October 5, 1992 and March 20, 2006, taking into account both the Asian financial crisis and the opening-up of China’s equity markets in recent years. First, I analysis the cointegration by utilizing Johansen’s (1988) cointegration tests. I find that a long-term equilibrium relationship measured by cointegration has been established among Shanghai, Shenzhen, Hong Kong and Taiwanese markets and, to a lesser degree, between these markets and the Singapore market since 1998. Secondly, this study examines causality by exploring the bootstrapped Toda-Yamamoto non-causality tests. I find that there is strong evidence of a bi-directional causality between Shanghai and Shenzhen markets after 1998. Furthermore, I also find that there are more causal linkages between the Chinese states equity markets: two mainland Chinese markets, Hong Kong, Taiwan, and Singapore became more dependent on each other. The robustness of the above findings is confirmed by the use of a bootstrap test employed to test the validity of my results.

Has the Financial Services Reform Act fixed the problems with the regulation of securities and derivatives?

The Financial Services Reform Act 2001 (Cth) introduced new definitions of“derivative” and “financial product” into the Corporations Act 2001 (Cth), andreplaced the separate regulatory regimes governing futures contracts andsecurities with a single financial markets authorisation regime and a singleintermediary licensing regime. This article examines the reforms to evaluatewhether they have been successful. It is argued that there are definiteimprovements resulting from the reforms, and the scope for regulatoryarbitrage has been greatly reduced. However, numerous problems remain.There are significant differences in the regulation of securities and deriva-tives. The distinction between securities and derivatives is still based on legalcharacteristics, not economic function. There is uncertainty as to the exactscope and interaction of the definitions, particularly with respect to equityderivatives, warrants and options. The current law has thus not fullyaddressed many of the problems that existed prior to the reforms.

German corporate governance in international and European context

The main aim with this book is to provide English speaking readers with a comprehensive overview of the German corporate governance model. The authors introduce the reader to the unique features of the German Business and Enterprise Law. The book deals with the most important company organs, namely the General Meeting, the Management Board and the Supervisory Board. The unique interplay among these organs are also covered and the reader is introduced to the particular dynamics of the German two-tier board structure.Further the authors deal with the dominant role of the "German banks" and new players in the German financial markets, focusing particularly on voting rights of these institutions at companies' general meetings and appointing members to companies' supervisory boards. Accounting is shown as the documentary proof of good corporate governance. The final chapter gives an overview of corporate governance in the European Union, the OECD Principles of Corporate Governance and corporate governance in the US, the UK and Australia.

The responsiveness of LPT returns and their attributes

The Australian listed property sector has experienced substantial growth over the past decade. Relative to international property markets, Australia has the highest percentage of listed real estate and the highest proportion that makes up the total equity market in the world, hence, making it an important component of domestic financial markets. This study employs the Stone (1974) two factor asset pricing model to investigate the sensitivity of Listed Property Trust (LPT) returns to market and interest rate returns from 2000 to 2005, and the characteristics (namely, management structure, specialisation and the degree of financial leverage) that may be driving these sensitivities. Our results indicate an increase in the market risk profile of LPTs, suggesting an erosion of the defensive benefits of LPTs against stockmarket volatilities.

Structural adjustment and change in the Australian life insurance industry post demutualization

Deregulation of financial markets has been an important platform for government policy in recent times. It has been a catalyst in the expansion of financial sector. The experience of Australian life insurers during this period represents an interesting case study into the impact of regulatory transition. The lifting of restrictions changed the institutional environment within which life insurers operated. In doing so it precipitated changes in strategies and organizational structures of these financial intermediaries. An information cost framework is used to analyse the consequences of deregulation and its implications for the Australian life insurance industry in emerging global financial markets.
