| Conservation and restoration of native vegetation is often a gradual process which may require many years to transform an ecosystem from one vegetative state to a target ecosystem. This process is stochastic, with some changes potentially irreversible. In contrast, contracts with landholders to undertake conservation measures on their property are typically for less than ten years and often make no contingencies for re-contracting at the end of the contract period. The risk to land holders and conservation agencies of contracts not being renewed and the consequent potential loss of previous investment means including covenants in conservation contracts may be attractive to both parties. A model is developed to empirically examine the optimal dynamic... |

| The allocation of benefits from research and development of new herbicide uses is dependent on patent status. The agricultural chemical industry will preferentially invest in herbicide R&D that increases the use of on-patent herbicides from which a company can capture a price premium. The distribution of benefits from increased use of on-patent herbicide will alter over time, with grain growers benefiting at the expense of agrichemical companies once the patent expires. Public sector investment in herbicide R&D may also benefit the agrichemical industry. The size and allocation of the benefits from R&D into on-patent herbicides is analyzed using economic surplus techniques. Two case studies are examined. One involves research into the choice... |

| Paying private landholders for environmental services, rather than input-based payments, has been proposed as a way to improve the performance of contracts for conservation agencies. A challenge is that the assessment of environmental services is subjective, raising the question of how assessment accuracy impacts on landholder behaviour and contract design. A model is developed of a contract between a conservation agency and a private landholder for the provision of environmental services. The model is used to estimate the impact of inaccurate and costly assessment on the optimal landholder labour effort and the optimal incentive payment. The model shows that inaccurate and costly assessment reduces the cost-effectiveness of the contract. Application of... |
