Trade-offs and implicit preferences in human mate selection

Two novel to domain research methods - choice modelling and the implicit Association Test (IAT) - were applied to measure trade-offs and implicit preferences in human mate preferences. Collectively, findings from four experiments supported the explanatory superiority of Sexual Strategies Theory as a model of between sex and within sex variability in mate preferences.

Predicting time trade-off health state valuations of adolescents in four Pacific countries using the assessment of quality-of-life (AQoL-6D) instrument

Objectives: Pacific Obesity Prevention in Communities (OPIC) is a community-based intervention project targeting adolescent obesity in Australia, New Zealand, Fiji, and Tonga. The Assessment of Quality of Life Mark 2 (AQoL-6D) instrument was completed by 15,481 adolescents to obtain a description of the quality of life associated with adolescent overweight and obesity, and a corresponding utility score for use in a cost–utility analysis of the interventions. This article describes the recalibration of this utility instrument for adolescents in each country.

Methods: The recalibration was based on country-specific time trade-off (TTO) data for 30 multiattribute health states constructed from the AQoL-6D descriptive system. Senior secondary students, in a classroom setting, responded to 10 health state scenarios each. These TTO interviews were conducted for 24 groups, comprising 279 students in the four countries resulting in 2790 completed TTO scores. The TTO scores were econometrically transformed by regressing the TTO scores upon predicted scores from the AQoL-6D to produce country-specific algorithms. The latter incorporated country-specific “corrections” to the Australian adult utility weights in the original AQoL.

Results: This article reports two methodological elements not previously reported. The first is the econometric modification of an extant multi-attribute utility instrument to accommodate cultural and other group-specific differences in preferences. The second is the use of the TTO technique with adolescents in a classroom group setting. Significant differences in utility scores were found between the four countries.

Conclusion: Statistical results indicate that the AQoL-6D can be validly used in the economic evaluation of both the OPIC interventions and other adolescent programs.

Trade-off manipulations in the development of negotiation decision support systems

Our model of negotiation for constructing Negotiation Decision Support Systems is based upon Principled Negotiation and uses trade-off manipulations in order to provide decision support. A resulting system, Family_Winner, was constructed using several information systems techniques. Trade-off Maps (a variant of Constraint Diagrams) are used to represent trade-off opportunities, while an empirically derived formula calculates the amount of compensation given to the ratings of issues remaining in dispute. The Issue Decomposition Hierarchy embedded in the system allows for the incorporation of sub-issues. Family_Winner was originally built for use in Australian Family Law. We believe our model can be extended for use in various other domains.

Family_Winner has been evaluated in the areas of industrial relations, international disputation and company disputes. Results from our evaluation suggest the system works satisfactorily in these domains. We conclude this paper by describing future projects that will develop and extend Family_Winner's functions and applicability.

Chinese construction industry performance after entry into the world trade organization

The Chinese construction industry has had significant activity in the international market in the last decade following the entry into the World Trade Organization (WTO). However the degree of activity and the sector performance is still relatively uncertain. A review of the literature in this field indicates that there is very little rigor in relation to adoption of quantitative measurement and performance indicators for internationalization, in particular for the measurement of the degree of internationalization specifically related to the international construction sector at both firm and country level. In addition the estimation of the influence and status of a country's construction activity in the international market has not been considered. There are useful indicators that we can borrow and consider from mainstream economics literature, such as, Dunning's Eclectic Paradigm (based on the ownership (0), location (L) and internalization (1) advantages of a firm) and Low et al.'s OLI+S Model (based on the Ownership, Location, Internalization and Specialty). Through an analysis of the attributes of the Chinese construction industry and a discussion on trends for the last decade, this paper proposes to develop a new model by adapting the Dunning model and acknowledging the significance of "Specialty" to measure the degree of internationalization both at the firm and country level. The International Level and Status Index was generated to measure the level and status of a country's construction industry in the international market by adopting the Depth Index (revenue composition), Height Index (top enterprises) and Width Index (fields involved). The key finding is that the degree of internationalization of Chinese construction industry and the status and influence of Chinese construction industry in the international market has not increased quickly. Surprisingly even though China had expectations of high growth after entry to WTO it has in fact declined. Contrarily, both of them declined in the early years after the accession to WTO.

Trade and industrial policy in developing countries : what scope for interfaces between agent-based models and computable-general equilibrium models

How best to assess trade and industrial policy in developing countries is a controversial question that unlocks a host of modelling complexities. Large computable general-equilibrium (CGE) models dominate many economic policy debates, but recent developments in the field have demonstrated that it is by no means clear that they give reliable results to questions of how trade reforms affect the poor. Over the last decade or so, a new approach to modelling complex systems has emerged using agent-based models (ABMs). This paper explores the question of whether ABMs are useful for economic policy-makers seeking to quantitatively model the effects of trade and industrial policies and whether constructive interfaces could be developed between CGE models and ABMs. The paper argues that in developing economic policy, ABMs can and should be used in conjunction with CGE models and that there is much to be gained from a greater understanding of the strengths and weaknesses of different modelling approaches, and what domains are most appropriate for their use. It concludes with some reflections on the reasons for the success of CGE approaches and ways in which ABMs could be made more widely understood and used among economists.

Maritime archaeology and trans-oceanic trade : a case study of the Oranjemund Shipwreck Cargo, Namibia

Routine sand dredging for alluvial diamonds at Oranjemund on the southern coast of Namibia exposed remnants of a long forgotten Portuguese merchant ship believed to have wrecked in the 1530s. The rescue excavations yielded over 40 tons of cargo consisting of thousands of gold and silver coins, tons of copper and lead ingots, and large quantities of ivory together with food refuse, part of personal possessions and the superstructure of the ship. This paper discusses the cargo from the shipwreck. The varying provenances show that overland inter-and intra-regional networks fed into the maritime trade between Europe and the Indian sub-continent. As such, the wreck is a lens through which we can view what was happening on the seas as well as on land. Finally we consider wider issues raised by this discovery relating to the protection and management of such material wherever it may be found in future.

Fiscal policy and US-Canadian trade

A factor-augmented vector autoregressive (FAVAR) model is applied to determine the effects of a rise in US government expenditure on the United States and Canadian economies. The results obtained reasonably characterize the effect of a rise in US government spending to the United States and Canadian economies emphasizing the role of the traded goods sector.

The recognition and protection of well-known trade marks in Indonesia

Legal context The recognition and protection of well-known marks in Indonesia has improved over the last few years for a variety of reasons.

Key points First, the Asian Crisis resulted in the creation of a Commercial Court, which is a clear improvement over the previously responsible District Courts. Secondly, the increasingly frequent publication of court decisions has improved transparency and consistency of those decisions. Well-known marks are now clearly protected against use for similar goods/services. Protection is extended to dissimilar goods/services by applying Article 16(3) TRIPS directly or by arguing that registration occurred in bad faith. Nevertheless, decisions thus far concern almost exclusively revocation and invalidity of registrations. Civil remedies such as damages and interim injunctions are hardly used, because the outdated civil procedural law has not familiarised judges with such legal instruments. Clearing the register of infringing registrations is another matter of concern. Cancellation for non-use for three consecutive years can be difficult, because the plaintiff is required to provide evidence of the last use in the production of the goods/services rather than in the course of trade more generally.

Practical significance While it has become much easier to protect well-known marks in Indonesia, much work remains to be done regarding the procedural framework of civil infringement proceedings and regarding the clearing of the register.
