For example, cost sharing for soil moisture-sensing technology or for irrigation technology updates are examples of subsidies. In such cases, targeting the right users and objectives can be critical, even challenging, in situations of information asymmetries. Even if well targeted, subsidy programs can be effective but they are also costly to the regulator. Moreover, if fine-scale spatial targeting is needed to achieve desired environmental goals, subsidies may be difficult to implement as they typically involve a voluntary signup to the incentive.
