The Effect of Mandatory Employer-Sponsored Insurance (ESI) on Health Insurance Coverage and Labor Force Utilization in Hawaii: Evidence from the Current Population Survey (CPS) 1994-2004

Using data from the Current Population Surveys, we examine the impact of Hawaii’s mandatory employer-sponsored insurance on health insurance coverage and employment structure in Hawaii. We find empirical evidence of three phenomena. First, private employer-sponsored insurance coverage for full-time workers (more than 20 hours per week) is more prevalent in Hawaii, other things held constant, than in other states and the U.S. as a whole. Second, there is avoidance of the employer-mandate in Hawaii by skirting the 20 hour rule, which changes the both the distribution of employment and the distribution of employment-based insurance coverage by hours worked. Third, Hawaii workers who match with part-time jobs without employer-sponsored health insurance obtain publicly provided health insurance or military coverage with higher probability than their counterparts elsewhere in the U.S. These results suggest that employer mandates induce both higher rates of coverage and labor market sorting.

Mitigating Runoff As Part of an Integrated Strategy for Nearshore Resource Conservation

This report first presents theoretical considerations for integrated resource management of forested watershed and nearshore resources, then estimates current economic benefits from nearshore resources (beaches and reef) as well as expected economic benefits, in the form of preserved nearshore resource benefits, from conservation of forest resources.

Optimal Management of a Renewable and Replaceable Resource: The Case of Coastal Groundwater

Endogenous Substitution Among Energy Resources and Global Warming

The theory of resource extraction has focused primarily on extraction when there is a single, homogeneous demand for the resource. In reality, however, we observe the simultaneous extraction of different resources such as oil, coal, and natural gas and multiple demands such as trasportation, residential and commercial heating, and electricity generation. This paper develops a model with multiple resources and grades and multiple demands. The model is simulated with extraction cost, estimated reserves, and energy demand data for the world economy. It is shown that if historical rates of cost reduction in the production of solar energy are maintained, more than 90 percent of the world's coal will never be used. The world will move from oil and natural gas use to solar energy. Global temperatures will rise by only about 1.5–2 degrees centigrade by the middle of the next century and then decline steadily to preindustrial levels, even without carbon taxes. These results are significantly lower than those predicted by the Intergovernmental Panel on Climate Change and suggest that the case for global warming may be seriously overstated.

Identifying Long-run Cointegrating Relations: An Application to the Hawaii Tourism Model

Abstract Cointegration analysis has gradually appeared in the empirical tourism literature. However, the focus has been exclusively on the demand side, neglecting supply influences and risking endogeneity bias. One reason for this may be the difficulty identifying structural relationships in a system setting. We estimate a demand-supply model of Hawaii tourism using a theory-directed sequential reduction methodology suggested by Hall, Henry, and Greenslade (2002). The resulting model illustrates the viability of such an approach as well its challenges.

The Contribution of the University of Hawai‘i to Hawai‘i’s Economy in 2003

The University of Hawai‘i had its beginnings in 1907 as a college of agriculture and mechanical arts and became the territoryís Land Grant College, a designation that remains today. With the establishment of the College of Arts and Sciences in 1920, the College of Hawai‘i became a University. Enrollment growth in the early years was slow, but the close of World War II and increased educational demand fueled by returning GIís increased the Universityís enrollment to over 5,000 students in the 1950s. Statehood and the establishment of the University of Hawaiëi as the ìstate university marked the beginning of a period of accelerating enrollment that resulted in the formation of a large diverse system. In 1965, the State Legislature created a statewide system of community colleges and placed it within the University of Hawaiëi. In 1970, the University of Hawai‘i at Hilo was founded. In 1989, West O‘ahu College, an upper division institution opened in 1976, was renamed the University of Hawai‘i-West O‘ahu. The flagship Manoa campus became the University of Hawai‘i at Manoa.

Tax Incentives in Tourism: Hawaii’s Hotel Remodeling and Construction Tax Credits

Fiscal incentives are widely used by governments around the world to attract private investment in “preferred” industries, including tourism. Incentives are often granted to offset actual or perceived differences in the cost of doing business in different political jurisdictions whether the cost differences arise from tax differences or from differences in transportation, labor, or other costs. Incentives raise the return to capital thereby making investment in a location more attractive.

Aging, Pension Income, and Taxes in Hawaii Report to the State of Hawaii Tax Review Commission

Over the foreseeable future, the number of retirees will grow much more rapidly than the number of workers.  The percentage of Hawaii’s population 65 and older is projected to increase from 13% in 2000 to 24.5% in 2030 and to nearly 30% by 2075. Currently there are about 22 persons 65 and older for every 100 persons of working-age (20-64).  By 2030 that number will more than double to 45 seniors for every 100 persons of working age.

Environmental Valuation and the Hawaiian Economy

Economic planning and policy analysis are commonly criticized for their failure to properly account for adverse effects of economic development on the environment and other interactions between nature and the market economy. The limited and piecemeal curbs on land development projects, e.g. as provided by environmental impact requirements, fail to diagnose the major negative impacts of the economy on development and to direct available resources to the most serious environmental problems in a cost-effective manner.

Inter-district Water Allocation with Conjunctive Use

Constrained conjunctive-use for endogenously separable water markets: managing the Waihole-Waikane aqueduct

An internal solution to an optimal control problem involving conjunctive-use of surface and groundwater may be inapplicable if water is not sufficiently fungible across space and time. We provide a more general solution and apply it to the problem of allocating a limited amount of water from the Ko‘olau mountains to two Oahu water districts separated by those mountains. The solution involves initially allocating all of the mountain water to the district supplied by groundwater but eventually allocating all of the water to the district supplied by surface water. The conditions for an internal solution hold only in the intervening years when some mountain water is allocated to each district.
