A perspective on credit derivatives

This contribution offers an explanation of credit derivatives as a group of financial instruments having a common purpose being the managing of credit exposures, and thus credit or default risk. This paper explores the links between their economic and financial manifestations and the legal bases for their widespread application. To ensure an understanding of the purposes served by each of the main types of credit derivatives, a detailed scrutiny of individual instruments is undertaken. Issues relating law and economics to trading in this type of derivative are investigated, then pricing issues and empirical evidence are considered. A summary brings together the range of features bearing upon the effective development of a market in these financial instruments.

Scaling the volatility of credit spreads: evidence from Australian dollar eurobonds

The linear rescaling of the variance of an asset's return is used by many asset pricing models when an annualised risk coefficient is required. However, this approach may not be appropriate for time series, which are not independent and identically distributed (IID). This paper investigates the scaling relationships for daily credit spreads, from January 1995 to May 1998, between AAA-, AA-, and A-rated Australian dollar denominated Eurobonds with maturities of 2, 5, 7, and 10 years. The credit spread return all display similar scaling properties with the estimated standard deviation, based upon a scaling at the square root of time, significantly underestimating the actual level of risk predicted from a normal distribution. These results have implications for risk managers and trading of credit spread instruments.

CO2 credit or energy credit in emission trading?

Emission trading is a good concept and approach to tackle global warming. However, what “currency” or “credit” should be used in the trading has remained a debatable topic. This paper proposed an “Energy Credit” concept as an alternative to the “CO₂ credit” that is currently in place. From the thermodynamic point of view, the global warming problem is an “energy balance” problem. The energy credit concept is thought to be more thermodynamically correct and tackles the core of the global warming problem more directly. The Energy credit concept proposed can be defined as: the credit to offset the extra energy trapped/absorbed in the earth (and its atmosphere) due to the extra anthropogenic emission (or other activities) by a country or company. A couple of examples are given in the paper to demonstrate the concept of the Energy credit and its advantages over the CO₂ credit concept.

Micro-credit programs and land distribution: a note

"Micro-credit" has come to refer to a popular extension strategy---usually in the agricultural sector---whereby a government or NGO extends credit at favorable rates to poorer borrowers, with repayment being supported by some kind of mortgage on the borrower's social capital. In the commonest case, eligibility is determined by the borrower's wealth, as indexed by his/her landholding. This note shows that, with an imperfect land market, the response to such a program will be to fragment landholdings which are smaller than a certain threshold, while larger holdings remain unaffected. Thus the pattern of landholding will tend to become more polarized.

Culture-specific variation in the flavor profile of soymilks

A modified quantitative descriptive analysis (QDA) method was used to determine sensory profiles of 8 soymilk products: 3 manufactured in Australia, 3 manufactured in Singapore, 1 manufactured in Malaysia, and 1 manufactured in Hong Kong. A panel (n= 7) was selected, trained in descriptive profiling of soymilk, and developed a soymilk language that was used to evaluate the flavor attributes of the soymilk products. A repeated-measure ANOVA showed highly reproducible panel performance, and significant differences in soymilk attributes among all soymilks. A principal component analysis (PCA) revealed 2 main groupings among the soymilks that corresponded to cultural origin: Australia and Asia (Singapore and Hong Kong/Malaysia). Products from Australia were significantly stronger in milky, astringent, salty notes and pale in color, while products from Asia were significantly stronger in beany, cooked beans, sweet, and pandan notes (P < 0.05). In addition, the Asian soymilks could be separated into 2 subgroups, with Singaporean soymilks having deeper color, greater viscosity, and less green flavor than Hong Kong/Malaysia soymilks. Australian produced soymilk is bovine-milk-like compared with Asian soymilk, presumably due to bovine milk being the primary source of milk in Australia. We conclude that culture-specific flavor preferences are a determining factor in flavor profiles of soymilks from geographically distinct regions.

Who`s complaining? Using MOSAIC to identify the profile of complainants

Purpose – The purpose of this article is to bring together established research in the field of consumer complaint responses: to contextualise this research into the area of complaints about advertising in Australia; and to empirically test the proposition that it is possible to construct a profile
of complainants about advertising in Australia.

Design/methodology/approach – Postcodes obtained from the Advertising Standards Board complaints database were entered into Pacific micro marketing MOSAIC software, which uses data at the postcode level to cluster individuals into homogeneous groups.

Findings – Characteristics shared among consumers who engage in “amplified voicing” include above average income levels, above average disposable income levels, higher than average education levels, professional and associate professional occupations, middle- to late-middle-aged household heads and above average representation of working women. Their interests tend towards culture, technology, entertaining, sport, food and fashion.

Research limitations/implications – Complainants seem to be unrepresentative of those most likely to be disadvantaged by “unacceptable” advertising. It is suggested that it now falls to advertising professionals and marketing academics to encourage greater involvement of all members of Australian society in the current complaints process and build wider understanding of practices that contravene the regulatory system.

Originality/value – This study investigates the effects of advertising on consumers and hence on society in general, and examines the changing nature and structure of the advertising self-regulatory system in Australia. Though based on fieldwork in Australia, it provides an international perspective, and is potentially transferable to other societies.

Partners of problem gamblers who present for counselling: demographic profile and presenting problems

This study examined the characteristics of partners of problem gamblers. The study participants were 440 partners, who sought help in a 12-month period from the publicly-funded Break Even counselling services in the state of Victoria, Australia. The analyses revealed that the partners of problem gamblers were far from an homogenous group, with having to face the consequences of another person's problematic gambling seeming to be the only common characteristic. Almost one-third (29.6%) of clients were male and with the exception of financial problems, which were more likely to be reported by females, the presenting problems were similar. When compared to all Victorians aged 15 years and over, greater proportions of male and female partners of problem gamblers were participants in the labour force.

Reconstruction of the refractive index profile of planar waveguides using ray tracing analysis

We propose a method for refractive index profiling based on measuring coordinates and angles of laser beams passing across the waveguide layer. Calculations are performed by solving an integral equation using new global optimization methods.

Reassessing Grameen Bank's micro credit programme for poverty alleviation in bangladesh : a new perspective

Rural finance has been a mltior policy in alleviating poverty in developing countries. Of specific interest are the micro credit programmes that target the poorest segment of the population. Despite some successes in particular settings, the efficacy of micro credit programmes has been a mltior concern in recent years. This paper evaluates the success of the Grameen Bank, the premier micro credit provider in rural areas in Bangladesh in the context of contemporary development philosophies. Only a few studies have evaluated the performance of the Grameen Bank from a poverty alleviation perspective. Many have evaluated the efficiency of the Grameen Bank's micro credit programmes using attributes such as the repayment rate. In this paper, we add a new dimension to the literature by arguing that if poverty alleviation is the ultimate objective, then the bank's micro credit programme should be assessed from the borrowers' perspective. Rural credit should be conceptualised not as just an input to production but as a mechanism for rural transformation. Our analysis reveals that while Grameen Bank is an efficient provider of micro credit in rural Bangladesh, its programmes fall short of achieving poverty alleviation for a multitude of borrowers and reshaping the process is hence a critical imperative.

Who are they? A profile of complainants about advertising in Australia

Advertising expenditure in Australia has almost doubled in the last 10 years even though some advertisements maybe ''unacceptable." We investigated consumer complaint responses specifically within the area of advertising in Australia. Our findings indicate that these complainants to be older, more highly educated and more likely to be female, than the population at large.

A profile of complainants about advertising in Australia: an agenda for research

Investigation of consumer complaint responses within the area of advertising in Australia stems from the suggestion that the more money spent on advertising in a country the greater the need for consumer protection from 'unacceptable' advertising. This research will allow the formulation of strategies to enable more effective marketing communications.
