Intergenerational Games with Dynamic Externalities and Climate Change Experiments

Dynamic externalities are at the core of many long-term environmental problems, from species preservation to climate change mitigation. We use laboratory experiments to compare welfare outcomes and underlying behavior in games with dynamic externalities under two distinct settings: traditionally studied games with infinitely-lived decision makers, and more realistic intergenerational games. We show that if decision makers change across generations, resolving dynamic externalities becomes more challenging for two distinct reasons. First, decision makers’ actions may be short-sighted due to their limited incentives to care about the future generations’ welfare. Second, even when the incentives are perfectly aligned across generations, increased strategic uncertainty of the intergenerational setting may lead to an increased inconsistency of own actions and beliefs about the others, making own actions more myopic. Access to history and advice from previous generations may improve dynamic efficiency, but may also facilitate coordination on noncooperative action paths.

UHERO County Forecast: Neighbor Island Tourism Still Has Room to Grow

After a rather soft 2014, the counties are poised for better performance over the next several years. Tourism will see additional healthy gains on the Neighbor Islands for the next two years, before rising occupancy and costs begin to bring down growth rates, something that has already occurred on Oahu. Construction, which has disappointed so far, will become a significant contributor to growth. Gains in employment have brought unemployment rates down substantially, and moderate expansion of jobs and income will continue, helping to solidify the local spending leg of the economic expansion.

Factors Affecting EV Adoption: A Literature Review and EV Forecast for Hawaii

Electric Vehicles (EVs) reduce or negate gasoline or diesel use in vehicles through integration with the electric grid. Both plug-in hybrid electric vehicles (PHEVs)—which can draw from a battery as well as liquid fuel—and battery electric vehicles (BEVs)—solely powered through electricity—provide the opportunity for power-sharing with the electric grid and can potentially ease the integration of sources of intermittent renewable energy. This is a potentially important technology to help reduce greenhouse gas (GHG) emissions, local air pollution, and vehicular noise.


In this paper, we review studies informing the factors that affect EV adoption. We also review and harmonize studies that develop forecasts of EV adoption over time. We select a set of forecasts that represent low, reference, and high EV adoption and apply them to Hawaii-specific EV and car sales data to provide a preliminary forecast of potential EV adoption in Hawaii.

Do Energy Efficiency Standards Hurt Consumers? Evidence from Household Appliance Sales

We examine the effect of energy efficiency standards on the clothes washers market using a constant-quality price index constructed from same-model price changes for a significant majority of clothes washer models sold in the United States between 2001 and 2011. We find constant-quality prices fell over time, while quality increased, particularly around times energy standards changed. We estimate total welfare changes by assuming the difference between average price and constant-quality price indicates average quality. Further examination shows product entry and exit are associated with changes federal standard for energy efficiency. With policy changes implicitly coordinating entry and exit, average vintage sharply falls when standards change. Controlling for individual model and time effects, we find that lower average vintage is associated with more rapidly falling prices, an effect we attribute to increased competition. We also find a strong relationship between clothes washer prices and average vintage of the same manufacturer, which indicates cannibalism explains much of the declining price of clothes washers over time. We apply the same methodology to other appliances (clothes dryer, room air conditioners and refrigerators) which did not experience simultaneous efficiency standard changes between 2001 and 2011. We see the same cannibalism in the market for clothes dryers, but not for room air conditioners or refrigerators. We also find notable improvements both in the characteristics of clothes washers that directly improve energy efficiency and those that promote convenience and space-saving. Energy efficiency standards appear to facilitate more rapid innovation and price declines.

Who Really Benefits from Agricultural Subsidies? Evidence from Field-level Data

If agricultural subsidies are largely capitalized into farmland values then expanding support for agriculture may not benefit farmers who rent the land they farm. Suddenly reducing subsidies may be problematic to the extent that land values already embody expectations about future subsidies. Existing evidence on the incidence of subsidies on land values is mixed. Identification is obscured by unobserved or imprecisely measured factors that tend to be correlated with subsidies, especially land quality and time-varying factors like commodity prices and adverse weather events. A problem that has received less attention is the fact that subsides and land quality on rented land may differ from owned land. Since most farms possess both rented and owned acreage, farm-level measures of subsidies, land values and rental rates may bias estimated incidence. Using a new, field-level data set that, for the first time, precisely links subsidies to land parcels, we show that this bias is considerable: Where farm-level estimates suggest an incidence of 20 to 79 cents of the marginal subsidy dollar, field-level estimates from the same farms indicate that landlords capture just 10–25 cents. The size of the farm and the duration of the rental arrangement have substantial effects. Incidence falls by 5–15 cents per acre when doubling total operated acres, and the incidence falls by 0.1–1.2 cents with each additional year of the rental arrangement. Low incidence of subsides on rents combined with the farm-size and duration effects suggest that farmers renting land have monopsony power.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

The negative consequences of long-term exposure to particulate pollution are well-established but many studies find no effect of short-term exposure on health outcomes. The high correlation of industrial pollutant emissions complicates the estimation of the impact of individual pollutants on health. In this study, we use emissions from Kilauea volcano, which are uncorrelated with other pollution sources, to estimate the impact of pollutants on local emergency room admissions and a precise measure of costs. A one standard deviation increase in particulates leads to a 23-36% increase in expenditures on ER visits for pulmonary outcomes, mostly among the very young. Even in an area where air quality is well within the safety guidelines of the U.S. Environmental Protection Agency, this estimate is larger than those in the existing literature on the short-term effects of particulates. No strong effects for cardiovascular outcomes are found.

Sumner La Croix on PBS Hawaii Insights: Will Our Children Ever Be Able to Afford to Live in Hawaii?

There seems to be no end to the rising cost of living in Hawaii. The high prices of housing, groceries, gas and other necessities make it more and more difficult for us to live in today's paradise. But what about our children? If it's this hard to make ends meet now, what will life in Hawaii be like for future generations? UHERO's Sumner La Croix joins Daryl Huff and guests on Insights on PBS Hawaii to discuss how these issues impact the islands' middle class residents.

Hawaii Construction Forecast: Construction Building Up

Posted March 27, 2015 | Categories: Forecasts

Last year’s construction gains were smaller than anticipated. Activity will ramp up a bit this year, as Kakaako condo building intensifies and new tourism-related projects add to the mix. The more attenuated schedule of rail building and lagging single-family development will generate a lower and later peak to the current construction cycle.

Economic Impact of the Natural Energy Laboratory Hawaii Authority Tenants on the State of Hawaii

The Natural Energy Laboratory Hawaii Authority (NELHA) contracted UHERO to estimate its economic impact on the State of Hawaii. NELHA currently accommodates 37 tenants ranging from companies bottling deep sea water to solar and biofuel companies. These tenants pay close to $2 million in rent, royalties and pass through expense directly to NELHA. In addition, they employ hundreds of people, purchase goods and services from local businesses, and invest in capital improvements at NELHA.

This research determines NELHA’s contribution to local business sales, employee earnings, tax revenues, and number of jobs in Hawaii from the expenditures of its tenants in 2013. NELHA provides additional benefits to the state of Hawaii that this study does not capture but are important to consider when evaluating NELHA’s overall footprint on the economy.

Creating "Paradise of the Pacific": How Tourism Began in Hawaii

This article recounts the early years of one of the most successful tourist destinations in the world, Hawaii, from about 1870 to 1940. Tourism began in Hawaii when faster and more predictable steamships replaced sailing vessels in trans-Pacific travel. Governments (international, national, and local) were influential in shaping the way Hawaii tourism developed, from government mail subsidies to steamship companies, local funding for tourism promotion, and America’s protective legislation on domestic shipping. Hawaii also reaped a windfall from its location at the crossroads of the major trade routes in the Pacific region. The article concludes with policy lessons.
