Estimating the Opportunity for Load-Shifting in Hawaii: An Analysis of Proposed Residential Time-of-Use Rates

Hawaii’s largest electric utility, Hawaiian Electric Company (HECO) and its subsidiaries recently proposed a Time of Use (TOU) pricing scheme for residential rates. The TOU scheme has three tiers of prices: daytime, on-peak, and nighttime. The proposed rates have the highest cost during the on-peak period from 5pm to 10pm. For Oahu, the lowest cost is at nighttime, from 10pm to 9am. The difference between high and low rates is $0.33/kWh. For Maui and Hawaii Island, the lowest cost is during the daytime, 9am to 5pm. The difference between high and low rates are $0.35/kWh and $0.50/kWh, respectively. It is not stated whether the rates will be implemented as an opt-in, opt-out or mandatory program. This report summarizes literature on time varying pricing for residential rates to inform Hawaii’s electricity stakeholders, including ratepayers and policy-makers, of the potential impacts and considerations regarding the potential for TOU pricing in Hawaii.

By the Time I Get to Arizona: Estimating the Impact of the Legal Arizona Workers Act on Migrant Outflows

In 2007, the State of Arizona passed the Legal Arizona Workers Act (LAWA) which required all employers to verify the legal status of all prospective employees. Replicating existing results from the literature, we show that LAWA displaced about 40,000 Mexican-born people from Arizona. About 25% of these displaced persons relocated to New Mexico indicating that LAWA had externalities on adjoining states.

UHERO County Forecast: Counties Share Positive Outlook, But Face Individual Challenges

Hawaii’s four counties are moving steadily forward, accommodating new visitors, restoring lost jobs, and growing household incomes. Prospects remain good for the next few years, supported by health in the US economy, local labor markets, and construction. Growth rates will begin to trend lower, as each county converges toward its trend path and as construction moves to, and then beyond, the next cyclical peak.

How Hawaii’s State Government Shares Transient Accommodation Tax Revenues With Its Local Governments

Many states in the U.S. give unrestricted financial support to their local governments. The reasons some state governments provide aid and others do not, and why a particular mode of revenue sharing is adopted remain unclear. This paper examines Hawaii’s recent effort at developing a model to allocate the state’s transient accommodation tax revenues between the State and the county governments. The paper documents the process and explains the rationale behind the model.

Filipino 2040: Environmental Resources, Shocks, and National Well-Being

The contribution of the environmental-resource sector to national well-being is the sum of natural resource depletion and environmental degradation. Inasmuch as existing resource stocks are below efficient levels, better enforcement of existing laws as well as policies that incentivize sustainable use are needed. Similarly, progressive royalty assessment of mineral resources can incentivize exploration without transferring the bulk of resource rents to private interests. In the case of pollution, the key is to face firms with the full costs of their production, e.g. through emission taxes and/or cap and trade systems. Calculating total depletion and degradation (TDD) will facilitate the calculation of green national income (GNI), a more inclusive metric of national well-being. In the same way, simultaneous optimization of disaster management policies in the face of climate change can facilitate a further improvement in national well-being, this time measured as comprehensive national income (CNI).

Cost-Benefit Analysis of Disaster Mitigation Infrastructure: The Case of Seawalls in Otsuchi, Japan

Disaster management problems often pose the same types of challenges that environmental governance problems do; they involve decision-makers at various levels and can transcend political boundaries. We conduct a benefit-cost analysis of a disaster adaptation strategy in Otsuchi, which was undertaken shortly after the 2011 Tohoku earthquake and tsunami devastated the region. Results indicate that present value net benefits from the planned seawall are positive, even if expected damages are low, provided that the wall is capable of reducing damage by at least 50%. A hybrid method of governance may, however, be effective at increasing the benefit-cost ratio.

Sustainable Agriculture Irrigation Management: The Water-Energy-Food Nexus in Pajaro Valley, California

The water-energy-food (WEF) nexus is quickly becoming one of the most critical global environmental challenges of the twenty first century. However, WEF systems are inherently complex; they typically are dynamic and span multiple land or agro-ecosystems at a regional or global scale. Addressing this challenge requires a systems approach to optimal and sustainable resource management across multiple dimensions. To that end, using Pajaro Valley (California) as a case study, our research aims to (1) highlight synergies and tradeoffs in food and water production, (2) build a dynamic framework capable of examining intertemporal resource relationships, and (3) detail the steps required to develop incentive-compatible financing of the resulting management plans when benefits are not distributed uniformly across users. Using a stylized model, we find that in the long run, inland growers benefit from the halting of seawater intrusion (SWI) due to overpumping of groundwater. We also calculate that the water provided by the proposed College Lake Multi-Objective Management Program—a plan designed to halt SWI and support sustainable water and agricultural development in the region—will generate net revenue of $40-58 million per year, compared to an annualized cost of less than $3 million. An equal cost-sharing plan would be desirable if the benefit of the project exceeded $1,268 per year for each well owner. Since this may not necessarily be the case for smaller well owners, one possible alternative is to allocate costs in proportion to expected benefits for each user.

A Review of the Current State of Research on the Water, Energy, and Food Nexus

The idea of the water-energy-food nexus was launched in earnest since at least the Bonn2011 Nexus Conference, when the German Federal Government organized the international Conference “The Water Energy and Food Security Nexus – Solutions for the Green Economy” to contribute to the United Nations Conference on Sustainable Development (Rio+20). According to the background paper prepared by Hoff for the Conference, the concept of the water-energy-food nexus emerged in the international community in response to climate change and social changes including population growth, globalization, economic growth, and urbanization (Hoff 2011). These issues are causing increased pressure on water, energy and food resources, presenting communities with an increasing number of tradeoffs and potential conflicts among these resources which have complex interactions. For example, demands for water, energy and food are estimated to increase by 40%, 50% and 35% respectively by 2030 (US NIC 2012). Although various nexus-related conferences, research initiatives and projects have been held around the world under such circumstances, water-energy-food nexus policy has not yet been initiated in Japan.

The Economic Value of Groundwater in Obama

Worldwide, freshwater is important not only for direct consumption but also for its role in the production of a variety of goods and services. For example, water is used for cooling nuclear reactors and as an input for the production of energy via hydroelectric processes. Freshwater also is essential for the production of food, including crops and livestock. Recognizing these synergies and identifying tradeoffs are key components of water-energy-food (WEF) nexus research (Taniguchi et al., 2013; Loring et al., 2013; Giampietro et al., 2014). In this study, we focus on Obama City, Japan, where groundwater is used directly for domestic and commercial consumption and for melting snow. Stored groundwater also provides an indirect benefit: submarine groundwater discharge (SGD) from the aquifer supports the nearshore ecology, including a locally important fishery. Using this case study, we document some common challenges that arise when undertaking WEF research and outline an example of an integrated approach that combines multiple modes of analysis to overcome those obstacles.

Creating Tourism Improvement Districts to Raise Stable Funding for Destination Marketing and Promotion

Tourism Improvement Districts (TIDs), modeled after the more well-known Business Improvement Districts (BIDs), are increasing rapidly in the U.S. With enabling legislation from state and local governments, TIDs allow hoteliers in a tourist destination to ban together to impose compulsory assessments on nearly all the hotels in the district in order to raise money to fund destination marketing. To date, research on TIDs have come almost exclusively from destination marketing organizations (DMOs), travel associations, TIDs, and consultants with vested interest in the formation and expansion of TIDs. This paper synthesizes information from available reports and attempts to provide a more balanced view of the role of TIDs in destination tourism marketing and promotion.
