Agri-environmental policy is modelled as a social welfare maximisation problem that recognises the potential trade-off between increased environmental benefit and increased cost of monitoring compliance. Moral hazard arises because monitoring does not detect all those who fail to comply with...

Agro-biodiversity can provide natural insurance to risk-averse farmers by reducing the variance of crop yield, and to society at large by reducing the uncertainty in the provision of public-good ecosystem services such as e.g. CO2 storage. We analyze the choice of agro-biodiversity by...

This article examines a self-enforcing contract between a risk-neutral principal and a risk-averse agent who is able to hold up values ex post. It shows that risk aversion and variance can only partly explain the contract's incentive intensity. Ex post bargaining power and outside options will...

Several empirical findings have challenged the traditional trade-off between risk and incentives. By combining risk aversion and limited liability in a standard principal-agent model the empirical puzzle on the positive relationship between risk and incentives can be explained.
