Willingness to pay for electric vehicles and their attributes

This article presents a stated preference study of electric vehicle choice using data from a national survey. We used a choice experiment wherein 3029 respondents were asked to choose between their preferred gasoline vehicle and two electric versions of that preferred vehicle. We estimated a latent class random utility model and used the results to estimate the willingness to pay for five electric vehicle attributes: driving range, charging time, fuel cost saving, pollution reduction, and performance. Driving range, fuel cost savings, and charging time led in importance to respondents. Individuals were willing to pay (wtp) from $35 to $75 for a mile of added driving range, with incremental wtp per mile decreasing at higher distances. They were willing to pay from $425 to $3250 per hour reduction in charging time (for a 50 mile charge). Respondents capitalized about 5 years of fuel saving into the purchase price of an electric vehicle. We simulated our model over a range of electric vehicle configurations and found that people with the highest values for electric vehicles were willing to pay a premium above their wtp for a gasoline vehicle that ranged from $6000 to $16,000 for electric vehicles with the most desirable attributes. At the same time, our results suggest that battery cost must drop significantly before electric vehicles will find a mass market without subsidy.     

Critical thinking in the public accounting profession: aptitudes and attitudes

The public accounting profession has called for enhanced critical thinking skills in accounting graduates. However, critical thinking is a term which does not enjoy a universally-accepted definition. This study attempts to identify the critical thinking competencies essential to success in public accounting, and articulates those competencies to facilitate future research aimed at curricular change to meet the needs of the profession. The findings reveal that the profession uses the term critical thinking to refer to a broad set of competencies which includes both cognitive and non-cognitive attributes, attitudes, and behaviors. These competencies are presented as an operational definition of critical thinking useful to accounting education researchers.     

Shapley value and disadvantageous monopolies

At least one monopoly in a two-sector model must be advantageous, according to the Shapley value. If the elasticity of substitution is a constant at least equal to one, then each monopoly has an advantage if the other sector is not monopolized. For elasticity of substitution less than one, monopoly may be disadvantageous, depending on the distribution parameter.     

Repressed inflation in the Soviet Union: A temporary equilibrium approach

The Soviet economy is modeled by means of temporary general equilibrium theory. Three temporary equilibrium states are distinguished. In Walrasian equilibrium, all markets clear. Under repressed inflation, there is excess consumer demand for goods marketed by the state, while consumer demand is deficient in the underconsumption regime. The dynamics of these temporary equilibrium states are studied and the dynamic adjustment equations fitted to Soviet data. Simulation of the model offers an explanation for the tendency of the inventories/cash balances ratio to fall since 1965.     

The future of the Affordable Care Act: will we abandon health care reform?

With obstacles to the Affordable Care Act (ACA) growing, nurses need to continue to educate themselves about the ACA and the issues it is designed to address. While it has many shortcomings, the ACA invests in creating a new infrastructure that holds the potential to improve care quality and contain costs. Health economist Victor Fuchs suggests three areas must change if we are to have a health care system that is quality focused: information, infrastructure, and incentives. The current health care legislation is noble and lays a basis for future structural cost containment. The health care system continues to unravel as our politicians remain polarized over reform efforts. We must engage or we will never find solutions, never see reform.     

Physicians’ use of medical technology: an analysis of the introduction and subsequent failure of drug-eluting stents

Using data on cardiac patients in Florida hospitals from 2003 to 2007, we analyse the adoption and deadoption of a major new medical technology, drug-eluting stents (DESs). The Food and Drug Administration approved DESs in April 2003 and physicians rapidly adopted the new technology. In March 2006, a presentation was made at the American Cardiology Conference which showed that patients receiving DES in real-world settings suffered higher rates of mortality and myocardial infarction than those receiving stents without drugs. We examine the utilization of DES from April 2003 to the end of 2007. Using a hospital fixed-effects model, we find that board-certified and top-trained physicians were initially quicker to adopt DES. Over time, this effect dissipated and top-trained physicians were less likely to use DES by the time new clinical trials indicated they could be problematic. After the news, board-certified and top-ranked physicians were less likely to change their behaviour. Physicians’ own experience also contributes to the use of technology and the effects are stronger for non-board-certified physicians. We conclude that even within hospitals, physician training and experience play an important role in explaining differences in rates of technology use.     

Core and value for a public-goods economy: An example

An example of a public-goods economy with a continuum of agents is presented in which the Shapley value does not lie in the core.
