Using choice modeling, we explore willingness to pay for rhino horn among existing and potential future consumers in Vietnam. We find that wild‐sourced horn, harvested humanely from the least rare species, is the most highly valued product. Furthermore, consumers are willing to pay less for rhino horn products under a scenario where international trade is legalized compared to the current situation of illegal trade. We discuss the potential implications of our findings on rhino poaching and international trade policy.

Comprehensive Investment (CI) may provide an indicator of future changes in a country's per capita consumption. The authors explore the utility of the CI indicator for Australia by constructing CI data since 1861 and by estimating their relationship with changes in future consumption over periods of 50 years ahead. The CI measures include changes in natural, produced and human capital, and make allowance for exogenous technological progress. The results are used to consider how Australia's natural capital exploitation influenced the consumption of future generations. Further, the authors gauge if low CI relative to other leading OECD countries resulted in lower consumption levels in Australia over time than feasible, had it saved more.

Impacts of regional productivity growth, decoupling and pollution leakage. Regional Studies. This paper examines the issues of decoupling regional economic growth and pollution and the extent to which pollution effects spillover regional/national borders. Specifically, a UK, regionally disaggregated, computable general equilibrium (CGE) model is used to investigate the relationship between economic growth and the level of CO₂ emissions posited by the ‘environmental Kuznets curve’ (EKC) conjecture using production accounting principle (PAP) and consumption accounting principle (CAP) environmental accounting methods. The simulation results suggest that at the regional level the existence of an EKC relationship depends on the source of regional growth and the how this relationship is specified.
