A contingent valuation study of scuba diving benefits: Case study in Mu Ko Similan Marine National Park, Thailand

Abstract Coral reefs, a major source of marine tourism, are under threat worldwide due to human activities. There is an urgent need for information that could be used to promote efficient marine park management. In this study the economic benefits associated with scuba diving in Mu Ko Similan Marine National Park, Thailand, is estimated using a single- and double-bounded dichotomous choice contingent valuation survey design. The results indicate that divers are willing to pay about US

Traditional production activities and resource sustainability

This paper conducts tests of the export-led growth and the import-compression hypotheses for four less developed countries (LDCs) – India, Nigeria, Fiji and Papua New Guinea (PNG). Based on Johansens multiple cointegration test preceded by unit root tests, we test for cointegration between real output, exports and imports. Non-rejection of cointegration between the variables excludes the possibility of Granger non-causality and suggests at least one way Granger causality. Real output, exports and imports are found to be cointegrated in two of the countries and the resulting error-correction models suggest that Granger causality runs from exports and imports to real output in these cases. Exogeneity tests are conducted for exports with respect to real output. However, while the assumption of weak exogeneity is validated in two of the countries, the null hypothesis of super exogeneity is rejected. The test results therefore cast doubts on policy recommendations for the LDCs based on the export-led growth hypothesis.

Customary marine tenure systems and sustainable fisheries management in Papua New Guinea

Environmental economics, which used to be on the periphery of the economics discipline, is fast becoming mainstream as concern for the environment grows. Practitioners in other disciplines (e.g. engineering, science, natural resource management, social sciences) are increasingly faced with environmental problems that have an economic component. This invaluable book fills an important gap in the literature by teaching both economists and non-economists how to use economic tools to address environmental problems.

The effects of foreign direct investment on Indonesian economic growth, 1970-1996

This paper investigates the effect of income inequality on health status. A model of health status was specified in which the main variables were income level, income inequality, the level of savings and the level of education. The model was estimated using a panel data set for 44 countries covering six time periods. The results indicate that income inequality (measured by the Gini coefficient) has a significant effect on health status when we control for the levels of income, savings and education. The relationship is consistent regardless of the specification of health status and income. Thus, the study results provide some empirical support for the income inequality hypothesis.
