The paper examines the extent to which tourism in the Great Barrier Reef and Wet Tropics World Heritage Areas can be said to be sustainable. To do this it provides a definition of sustainable tourism for protected areas, in terms of ecological economics criteria. Tourism, and its management, in the two World Heritage Areas is described, and the outcomes are assessed against the definition of sustainable tourism. The available data is not sufficient to permit a definitive overall assessment. However, a favourable interim verdict appears justified against environmental criteria in the case of the Great Barrier Reef. There is in both cases a dearth of suitable data for proper assessment against economic criteria. The criteria proposed and the assessment exercise reported provide a contribution to developing ways to evaluate sustainable tourism.     

Buyer-supplier relational characteristics and joint decision making

This paper explores propositions dealing with the influence of buyer-supplier relational characteristics on their joint decision making. Specifically, the proposed conceptual framework focuses on the link between three relational constructs (trust, commitment, relationship maturity) and two types of joint decision making (strategic and tactical). Strategic decisions are those that “expand the pie” for both parties (integrative decisions), and tactical decisions are those that “divide the pie” between the two parties (distributive decisions). We propose that the effect of relational characteristics on joint decision making is likely to be moderated by the characteristics of the supplier organization (such as team orientation) and its environment (such as competitive intensity). We conclude with a brief discussion of the implications and possible extensions of the theoretical model.     

Insurance Market Effects of Risk Management Metrics

We extend the classical analysis on optimal insurance design to the case when the insurer implements regulatory requirements (Value-at-Risk). Presumably, regulators impose some risk management requirement such as VaR to reduce the insurers’ insolvency risk, as well as to improve the insurance market stability. We show that VaR requirements may better protect the insured and improve economic efficiency, but have stringent negative effects on the insurance market. Our analysis reveals that the insured are better protected in the event of greater loss irrespective of the optimal design from either the insured or the insurer perspective. However, in the presence of the VaR requirement on the insurer, the insurer's insolvency risk might be increased and there are moral hazard issues in the insurance market because the optimal contract is discontinuous.     

University of Texas Roundtable on Financing and Managing Energy Investments in a Low‐Price Environment

During the past 18 months, the U.S. oil industry has seen oil prices plunge from well over $100 a barrel to under $30. In a session that was part of a recent Private Equity Conference at the University of Texas in Austin, the CEO of a small independent producer and a representative of a large global oil and gas company discussed the challenges of financing and operating energy companies in today's low‐price environment with the director of energy research at a brokerage firm, the senior partner responsible for the natural resource investments of a well‐known private equity firm, and the head of the oil and gas restructuring practice of a national law firm. The panelists appeared to reach a consensus on at least the following three arguments:

Optimal portfolios under worst-case scenarios

In standard portfolio theories such as Mean–Variance optimization, expected utility theory, rank dependent utility heory, Yaari’s dual theory and cumulative prospect theory, the worst outcomes for optimal strategies occur when the market declines (e.g. during crises), which is at odds with the needs of many investors. Hence, we depart from the traditional settings and study optimal strategies for investors who impose additional constraints on their final wealth in the states corresponding to a stressed financial market. We provide a framework that maintains the stylized features of the SP/A theory while dealing with the goal of security in a more flexible way. Preferences become state-dependent, and we assess the impact of these preferences on trading decisions. We construct optimal strategies explicitly and show how they outperform traditional diversified strategies under worst-case scenarios.     

Virtual schools

Virtual schools have already made their appearance. This paper examines the factors which promote or slow the spread of virtual schools. Technological change, economic rationalism, and the suitability of conventional schools for the information age are identified as reasons for the continued growth of virtual schools. Conversely, the identification of an appropriate pedagogy, the lack of required teaching skills, concerns for the reshaping of human values, socialisation, and the continued need for student supervision are seen as reasons why virtual schools will not rapidly overtake conventional ones. It is concluded that virtual schools will continue to increase in the 21st century, and that appropriate planning must be made for their impact.
