Conventional wisdom suggests that subsidising biofuel production will reduce greenhouse gas (GHG) emissions. This paper shows that in many cases, and for a wide range of parameter values, this is not true. Biofuel subsidies can generate supply-side response by fossil fuel producers that...

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 explains the large differences in cross-country productivity performance by modeling and testing the effects of social barriers to communication on productivity and capital accumulation. In an optimal growth model, social barriers to communication that impede the formation of knowledge...

The paper analyses the economic payoffs from marine reserves using a stochastic optimal control model. The results show that even if the reserve and harvested populations face the same negative shocks, harvesting is optimal, the population is persistent and with no uncertainty over current stock...

Using data from what was once one of the world’s largest capture fisheries the economic value of a marine reserve is calculated using a stochastic optimal control model with a jump diffusion process. The results show that with a stochastic environment an optimal-sized marine reserve can...

The paper provides the first ex-post estimates of the effects on technical efficiency of input controls in a fishery. Using individual vessel data from the northern prawn fishery of Australia for the years 1990–1996 and 1994–2000, a stochastic production frontier is estimated to analyse the...

The paper presents the first ex-post analysis of profit and productivity of individual vessels following a vessel or licence buyback in a fishery. Using individual firm-level data for the period 1997-2000, the paper analyzes a “natural experiment" of the effects of a 1997 scheme to reduce...

Unpredictable environmental fluctuations are a major problem in fisheries. To mitigate these uncertainties, reserves are advocated to help ensure population persistence, reduce population and harvest variance and to provide a ‘hedge’ against management failures. Using recent insights from...

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...

The paper investigates institutional reforms in Vietnam and their impact on the economic performance of firms. Using the provincial competitiveness index 2006 (PCI06) and firm-level data in Vietnam in 2005, the results show that provincial competitiveness is economically and statistically...
