The OECD has a Policy Highlight document out, summarising two forthcoming publications on the governance of land use. In it (page 17) it advocates for Land Value Tax:
If governments aim to encourage efficient land use within urban areas, they may also consider the introduction of a pure land value tax, which provides particularly strong incentives for an efficient use of the most valuable land. In contrast to property taxes, a pure land value tax does not tax sparsely built-up land less than densely built-up land. Thus, it makes it unprofitable to use expensive land at low densities and encourages densification especially in the centres of the most expensive cities.
