Effects of alternative pricing structures on electricity consumption and payments in the commercial and industrial sector
Abstract: We investigate the distributional and welfare impacts when commercial and industrial (C&I) electricity end users face a dynamic pricing structure as opposed to a constant volumetric price with demand charge on individual users’ peak usage. While demand charge does not necessarily reduce the system-wide peak, it often constitutes a large share of C&I users’ […]
Read MoreSea level rise risk interactions with coastal property values: a case study of O‘ahu, Hawai‘i
Abstract: Climate change-induced sea level rise (SLR) will affect a range of coastal assets and prompt difficult decisions about coastal land use across the world. Several recent studies find that current and projected SLR is associated with relatively lower property values. We contribute to this growing body of research with a case study of O‘ahu, […]

Read MoreEmbracing TOU: Nudges, Rates, and Renewable Energy
By Michael Roberts, Nori Tarui and Ethan Hartely Hawaiian Electric Company is about to embark on a significant experiment: a pilot program introducing time-of-use (TOU) pricing. Designed to reduce electricity prices during daylight hours when solar power is abundant and increase them during the evening when the sun sets and demand rises, this initiative could […]
Read MoreManaging retreat for sandy beach areas under sea level rise
Abstract: Sea level rise (SLR) is projected to impact approximately one billion people by 2100. For many coastal communities, retreat is the most viable long-term option due to exposure risk under SLR and increased coastal hazards. Our research analyzes the costs of retreating coastal development at an iconic beach in Hawaiʻi that is experiencing severe […]
Read MoreWhat’s a (Better) Beach Day Worth? Economic Valuation of Changes in Waikīkī Beach Characteristics
Abstract: Whether beach nourishment, an established beach management measure, is justified depends on its benefits and costs. We apply a discrete choice experiment at Waikīkī Beach on Oʻahu with mixed logit and latent class models to evaluate recreationists’ willingness to pay for changes in beach width and water clarity as well as the preferences for […]
Read MoreOpen Access Renewable Resources, Urban Unemployment, and the Resolution of Dual Institutional Failures
This paper investigates how poverty reduction and natural resource preservation can be simultaneously achieved in a small open dual economy with urban wage rigidity, open access rural resources, and rural-urban migration. An increase in the export tax rate on the rural resource good increases urban unemployment in both the short run and the long run with resource […]
Read MoreYou can’t always get what you want: Protectionist policies with the transport sector
This paper incorporates key stylized facts about the transport sector into the conventional international oligopoly model and explores how protectionist policies perform differently when transport costs are endogenous and subject to the backhaul problem (i.e., the imbalance of shipping volume in outgoing and incoming routes). A country’s protectionist policies, which benefit domestic firms and harm foreign firms in the […]
Read MoreWhat do families in Hawaiʻi use electricity for?
By Nori Tarui and Pratistha Gyawali CDA Project Dashboard IntroductionThe dashboard illustrates Hawaiʻi’s residential electricity usage based on the 2019 Residential Energy Use Survey, a residential appliance saturation survey conducted by Hawaiian Electric Company. UHERO applied the conditional demand analysis (CDA), which is a statistical method to estimate average annual consumption associated with each appliance […]
