We contribute to the understanding of marine reserves and the management of renewable resources with uncertainty. We show that the key benefit of reserves is that they increase resilience, or the speed it takes a population to return to a former state following a negative shock. Resilience can...

Analytical results for steady-state values of the biomass that maximises the sum of inter-temporal economic profits (dynamic bMEY) are derived in terms of a generalised harvesting function. The conditions under which dynamic bMEY exceeds the biomass that maximises the sustained yield (bMSY) are...

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...

The causes of overfishing are reviewed along with deficiencies in top-down input-regulated fisheries management. An alternative is the three pillars of fisheries policy intended to ensure sustainable, economically viable fisheries and marine ecosystems. The first pillar are incentives that...

Using energy data over the period 1981–2011 we find that US biofuels subsidies and production have provided a perverse incentive for US fossil fuel producers to increase their rate of extraction that has generated a weak green paradox. Further, in the short-run if the reduction in the CO2...

Using data from what was once one of the world’s largest capture fisheries, the northern cod fishery, the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump-diffusion process. Counterfactual analysis shows that with a stochastic environment an...

We examine how scarcity pricing can be used to assist with urban water demand management in Sydney in low rainfall periods using an estimated aggregate daily water demand function. Modelling shows that current water supplies and water prices are inadequate to prevent Sydney reaching critically...

The paper analyses how barriers to communication across social groups affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labour, social barriers to communication are shown to...

The paper estimates an aggregate daily water demand for Sydney using rainfall, temperature, and price data from 2001 to 2005, and a dummy variable to account for reductions in demand following the introduction of water restrictions in October 2003. Analyses based on the estimated price...

The paper analyzes how social barriers to communication affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labor, a negative relationship is shown to exist between social...
