Effect Of Weather Delays On Shareholder Value: Evidence From The Airline Industry, Jayendra Gokhale, Sunder Raghavan Jun 2015

Effect Of Weather Delays On Shareholder Value: Evidence From The Airline Industry, Jayendra Gokhale, Sunder Raghavan

Publications

Airlines measure service quality based on different factors such as on-time performance, delays and cancellations, mishandled baggage and denied boardings. Among the above factors, recent studies show that long delays and cancellations have a major impact on airlines bottom line not only in terms of current costs but also in terms of loss of future revenue. Finance literature tells us that stock prices reflect the present value of future cash flows. In this paper we use event study methodology to examine how weather delay and cancellations affect current stock market returns for our sample airlines. We find some evidence that …


Does Defensive Medicine Reduce Health Care Spending?, Scott Barkowski Feb 2015

Does Defensive Medicine Reduce Health Care Spending?, Scott Barkowski

Publications

The medical community often argues that physician fear of legal liability increases health care spending. Theoretically, though, the effect could be positive or negative, and empirical evidence has supported both cases. Previous empirical work, however, has ignored the fact that physicians face risk from industry oversight groups like state-level medical licensing boards in addition to civil litigation risk. This paper addresses this omission by incorporating previously unused data on punishments by oversight groups against physicians, known as adverse actions, along with malpractice payments data to study state-level health care spending. My analysis suggests that health care spending does not rise …

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, A. Stolzer, Anthony Brickhouse, Antonio Cortes, Dan Mccune, Jayathi Raghavan, David Freiwald

Publications

The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …


New Environmental Demands And The Future Of The Helsinki−Tallinn Freight Route, Olli-Pekka Hilmola, Harri Lorentz, Dawna L. Rhoades Jan 2015

New Environmental Demands And The Future Of The Helsinki−Tallinn Freight Route, Olli-Pekka Hilmola, Harri Lorentz, Dawna L. Rhoades

The environmental friendliness of short sea shipping has been justified in Europe by the ensuing lower congestion at hinterlands and unneeded large-scale infrastructure investments on roads and railways. However, the attractiveness of short sea shipping is about to change. This is because of increasing environmental regulations (International Maritime Organization (IMO) sulfur regulation in the Baltic Sea and planned CO2 emissions trading) and increased world market oil prices. In this research, we analyze this potential change using data envelopment analysis on the existing transportation chain alternatives in the Helsinki (Finland)−Tallinn (Estonia) short sea route (chains using either roro, ropax or container …
