Home is where the hurt is: an econometric analysis of injuries caused by spousal assault

Using data on injuries presenting at the emergency departments of participating hospitals in the Australian state of Queensland we examine the nature of injuries resulting from spousal assault and compare them to injuries from nonspousal assault and accidental injuries. We ask: who are the persons most vulnerable to spousal assault?, Are spousal assault injuries more (or less) severe than injuries from nonspousal assault and accidental injuries? Do the recorded figures for assault injuries on women understate the true number of assault injuries, and if so, by how much?

Community discussions: a vision for cutting the costs of end-of-life care

Palliative care involvement with patients with advanced disease has demonstrated significant cost savings at end of life (EOL). These financial benefits are largely due to improved EOL decision making. Assisting patients and families to examine their values and determine their preferences makes it possible to match patient goals with appropriate care. Often, comfort-oriented care is favored, avoiding the costs of medically aggressive, often futile, technology-driven interventions. Community-based EOL care discussions would demonstrate increased cost reductions while facilitating significant patient and family satisfaction with care.     

On the potential economic costs of cutting carbon dioxide emissions in Portugal

The objective of this paper is to estimate the impact of reducing carbon dioxide emissions from fossil fuel combustion activities on economic activity in Portugal. We find that energy consumption has a significant impact on macroeconomic activity. In fact, a 1 ton of oil equivalent permanent reduction in aggregate energy consumption reduces output in the long term by €6,340. More importantly, and since carbon dioxide emissions are linearly related to the amounts of fuel consumed, our results allow us to estimate the costs of reductions in carbon dioxide emissions. We estimate that a uniform standard for reducing carbon dioxide emissions from fossil fuel combustion activities would lead to a marginal abatement cost of €95.74 per ton of carbon dioxide. This is a first rough estimate of the potential economic costs of policies designed to reduce carbon dioxide emissions. At this level one may conclude that uniform, across the board reductions in carbon emissions would have a clear negative effect on economic activity. Hence, at the aggregate level there is clear evidence for a trade-off between economic performance and a reduction in carbon emissions. This opens the door to the investigation of the scope for policy to minimize the costs of environmental policy and regulation.

HMO coverage of cosmetic procedures: Response to market competition

Theory suggests that insurance policies should not cover purely cosmetic procedures. This paper attempts to explain empirical variation in coverage of a purely cosmetic procedure. Health maintenance organizations (HMOs) are modeled in a Cournot competition with two decisions—the number of policies and the limits placed on medical care utilization. Comparative statics for an individual market suggest, first, that restrictiveness is positively associated with the number of HMOs. Second, restrictiveness is positively associated with the predisposition to demand managed care products. Third, each effect is strengthened by increasing the other parameter. Restriction of tattoo ablation, a purely cosmetic procedure, is examined empirically. The first and second predictions are supported at low levels of predisposition and numbers of HMOs, while the third prediction is not supported. The data were obtained under a grant from the Office of Technology Assessment (HMO Laser Procedure Coverage) and a University of Michigan Rackham Pre-Doctoral Fellowship (InterStudy and County Business Patterns).     

Journey to Magnet: cost vs. benefits

As hospitals and health systems strive to be an "Employer of Choice", one important goal for their nursing leaders has been the decision to embark on their journey of becoming a designated Magnet facility. Approximately 12 months ago, conversations with a few chief nursing executives uncovered a hot topic concerning the achievement/designation of Magnet status and specifically its cost benefits. With more and more hospitals obtaining Magnet status, these nurse leaders did not know how other organizations felt about their journey including outcomes and were very interested in learning more details about their colleagues' experiences.     

Differentiability of the cost functions is equivalent to strict quasiconcavity of the production functions

The assumption that cost functions are differentiable with respect to input prices is equivalent to the assumption that production functions are strictly quasiconcave.     

Endogenously chosen travel costs and the travel cost model: an application to mountain biking at Moab,Utah

The travel cost model is frequently used to estimate net willingness to pay for recreation at remote sites by using the visitor's travel costs as a proxy for the price of recreation. However, some concern has been raised over the validity of using the visitor's stated travel costs as a proxy for price. This paper addresses some of these concerns, by examining the possible over-estimation of consumer surplus due to endogenously chosen travel costs. This paper extends past theoretical work for the linear model by developing a correction for endogenously chosen travel costs in more commonly used nonlinear models such as the Poisson or count data model. Also provided is the first empirical test of the presence of endogeneity and an estimate of the magnitude of the error from ignoring endogeneity in travel costs. After applying this test and the correction to data that was gathered for mountain biking at Moab, Utah the estimate of consumer surplus falls from US $153 to US $135, which is a 12% reduction.     

The costs of uncoordinated regulation

Patents encourage firms to undertake research and development by protecting innovator revenues from competition. Controls on pollution of the environment are intended to close the gap between the private and social costs of natural resource use. This paper examines the incentives that are created by the interaction of these two separate pieces of regulation. A model is developed that shows how an incumbent, patent-holding firm can take advantage of environmental regulation to exclude rivals from her market.     

The macroeconomic costs of conflict

Macroeconomic costs of conflict are generally very large, with GDP per capita about 28 percent lower ten years after conflict onset. This is overwhelmingly driven by private consumption, which falls by almost 25 percent ten years after conflict onset. Conflict is also associated with dramatic declines in official trade, with exports (imports) estimated to be 58 (34) percent lower ten years after conflict onset. The onset of conflict often also induces significant refugee outflows to neighboring non-advanced countries in the short run, and relatively small but very persistent refugee outflows to advanced countries over the long run. To alleviate reverse causality concerns between GDP and conflict onset, we control for pre-conflict GDP forecasts from the IMF World Economic Outlook and show that similar results are obtained with and without pre-conflict GDP forecasts.
