The presence of transaction costs in trading implies a non-linear adjustment process of real exchange rates towards Purchasing Power Parity (PPP). This may make the traditional tests for PPP using a linear framework, which generally tend to refute the PPP hypothesis, unreliable. This study...

This paper proposes a new procedure to test for a unit root in a nonlinear framework, with three separate contributions. First, the study proposes a modification of the ESTAR model to account for cases where the adjustment mechanism towards equilibrium is not symmetric. Second, we develop a...

Survey data from 10 OECD countries are used to model household water demand. Statistically significant results include: (1) an inelastic average price response is estimated for every country; (2) households not charged volumetrically consume more water than households that are; (3) household...

This paper analyses productivity, profitability and efficiency by climate zone for the WA grains industry over the past 30 years. More specifically, following the studies by the Department of Agriculture and Food of Western Australia (2011) and Che, et.al (2012), this paper uses the Törnqvist...

Analysing Vietnam's rice export policy and recent export ban in the context of rising food prices, this study combines insights from a regionally-disaggregated or 'bottom-up' CGE model and a micro-simulation using household data. Three main conclusions are drawn. First, although there is little...

This paper re-examines the sources of inequality in Vietnam, a transitional economy with large reductions in poverty from recent and dramatic economic growth, but vastly unequal gains across ethnic groups. Using an instrumental variable approach to provide consistent estimators of explanatory...

Australia supports the control of tuberculosis in Papua New Guinea for reasons of aid effectiveness and a desire to decrease the chance of importing tuberculosis to Australia. This paper analyses the case for this support using both cost-utility and cost-benefit analysis. We reach three...

This paper presents the results of the first natural experiment in the stated preference literature that tests for the stability of environmental values in the event of a catastrophic natural disaster. Two subsequent choice experiment surveys were conducted in Southeast Queensland, a region of...

This study aims to provide an estimate of non-consumptive use and non-use values for controlling invasive pest species in Queensland’s bioregions. Bioregions are geologically and ecologically distinct land areas. Bioregion specific values are estimated to assist the development of landscape...

The aim of the study was to understand public understanding of biosecurity and provide an estimate of the non-consumptive use and non-use benefits to be derived from enhanced biosecurity measures in the Southeast Queensland region. A public survey was conducted there during January 2011 using...
