Measuring environmental (dis)amenity value during a pandemic: Early evidence from Maryland

Capitalisation of multiple ecosystems on property prices in Auckland, New Zealand

Ecosystems and their associated services have become essential in policymaking as they often have implications for the welfare of those who live nearby. Coupled with the shift toward integrating green infrastructure, ecosystem services, and nature-based solutions in urban and environmental planning, ecosystems may capitalise on property prices. But a potential phenomenon in applications of hedonic prices models is the offsetting between amenities and disamenities values, which may result in insignificant marginal effects. Some strategies to mitigate this phenomenon involve introducing a greater categorisation of open spaces and housing submarkets typology. Hence, this paper explores the capitalisation patterns of 14 terrestrial and aquatic ecosystems across the housing market segments of Auckland, New Zealand's largest city. We used a dataset of 274 thousand sales transactions between January 2011 and December 2019. Models are estimated via OLS and unconditional quantile regressions (UQR) to account for heterogeneity, outliers and heavy-tailed distributions. UQR produce more accurate estimates of the implicit prices and lead to more effective policy recommendations. We find multiple capitalisation patterns across the prices distribution and confirm offsetting effects when ecosystems are not controlled as separate variables. This paper informs land-use decisions involving the preservation or creation of natural spaces in residential areas and improves our understanding of the interaction between their economic valuation and regional diversity.

Changes in Amenity Values after COVID‐19 Lockdowns in Auckland, New Zealand

In the fight against the COVID‐19 pandemic, New Zealand stood out with its ambitious elimination goal and the small death count per capita. The country’s strategy included full lockdown measures that were strict by international standards. In this paper we investigate whether New Zealand’s strict lockdowns brought significant changes to the dwelling price capitalisation of environmental amenities. Our results show a nuanced landscape. While before the pandemic, Auckland homebuyers were willing to pay a premium for dwellings located adjacent to open spaces, such premium either vanished or became a penalty during the lockdown phases. There was also a significant premium for dwellings within 300 m of beaches. But again such premium either decreases or becomes a penalty across the lockdown phases. In addition, we find a preference for dwellings located further away from Auckland CBD. Hence, some amenities that used to have a positive (or neutral) impact on the price of a property have now become disamenities from homebuyers’ perspective after the experience of the pandemic. This paper informs planners, policy‐makers and private actors with a better understanding of the behaviour of Auckland’s housing market under the disruptions due to the pandemic and lockdowns.
