Identifying wastewater management tradeoffs: costs, nearshore water quality, and implications for marine coastal ecosystems in Kona, Hawai‘i
Untreated and minimally treated wastewater discharged into the environment have the potential to adversely affect groundwater dependent ecosystems and nearshore marine health. Addressing this issue requires a systems approach that links land use and wastewater management decisions to potential impacts on the nearshore marine environment via changes in water quality and quantity. To that end, […]
Read MoreThe Effects of Utility Revenue Decoupling on Electricity Prices
Revenue decoupling (RD) is a regulatory mechanism that allows adjustments of retail electricity rates for the regulated utility to recover its required revenue despite fluctuations in its sales volume. The U.S. utility data in 2000–2019 reveals that RD is associated with about a 4-percentage point higher growth rate of residential electricity prices within the first year after […]
Read MoreThe unintended consequences of increasing returns to scale in geographical economics
Increasing returns to scale is the basis for many powerful results in economics and economic geography. But the limitations of assumptions about returns to scale in economic growth theories are often ignored when applied to geography. This leads to an unintentional bias favoring scale and mistaken conclusions about geography, scale and growth. Alternatively, this bias […]
Read MoreAustralia’s Forgotten Copper Mining Boom: Understanding How South Australia Avoided Dutch Disease, 1843–1850
Abstract: Great Britain established the new colony of South Australia (SA) in 1834, and migration from Britain to the colony began in 1836. After seven turbulent years, the discovery of two large deposits of copper at Kapunda (1843–4) and Burra (1844–5) renewed the colony’s economic prospects. Over the 1845–50 period, SA supplied roughly 9 per […]
Read MoreThe Economics of Health and Migration
Abstract: Migration and health are intimately connected. It is known that migrants tend to be healthier than non-migrants. However, the mechanisms for this association are elusive. On the one hand, the costs of migration are lower for healthier people, thereby making it easier for the healthy to migrate. Empirical evidence from a variety of contexts shows […]
Read MoreProducing valuable information from hydrologic models of nature‐based solutions for water
UHERO’s Leah Bremer and a group of international collaborators shed light on ways that ecosystem service modeling can better support real-world decision making through attention to the type of decision maker and to the salience, legitimacy, and credibility of information generated.
Read MoreThe local labour market effects of light rail transit
Many US cities have made large investments in light rail transit in order to improve commuting networks. I analyse the labour market effects of light rail in four US metros. I propose a new instrumental variable to overcome endogeneity in transit station location, enabling causal identification of neighbourhood effects. Light rail stations are found to drastically improve […]
Read MorePriority watershed management areas for groundwater recharge and drinking water protection: a case study from Hawai‘i Island
Worldwide, water utilities and other water users increasingly seek to finance watershed protection and restoration in order to maintain or enhance water quality and quantity important for drinking water supply and other human use. Hydrologic studies which characterize the relative effectiveness of watershed management activities in terms of metrics important to water users are greatly […]
Read MoreEffects of land cover and watershed protection futures on sustainable groundwater management in a heavily-utilized aquifer in Hawai‘i
Groundwater sustainability initiatives, including sustainable yield and watershed policy protection policies, are growing globally in response to increasing demand for groundwater, coupled with concerns about the effects of climate and land-cover change on groundwater supply. Improved understanding of the impacts of watershed management on groundwater yields and management costs—particularly in the broader context of climate […]
