In the choice between alternative environmental policy instruments, economists tend to favor policies capable of attaining cost-efficiency, but other considerations may be more important to stakeholders. We perform a choice experiment modeled on Swedish water and marine policy to estimate preferences for different policy instruments among citizens and municipal civil servants. Both the modal citizen and the modal civil servant prefer direct regulation and subsidies to nutrient trading. Moreover, nutrient trading is unlikely to deliver sufficiently large cost savings for civil servants to prefer it to other instruments. These results are consistent with the apparent reluctance to adopt water quality trading in Europe.
