The availability of health data has implications for individual patients, health-care systems and policymakers, yet despite advances in information management, patient health records to a large extent are still scattered and difficult to retrieve. A research team at the W. P. Carey School of Business created a database of patient information that aggregates information about disease and treatment from physicians, clinics and hospitals without compromising confidentiality. The database has been useful to health-care planners and public health researchers — and is a model of local innovation as the nation moves toward the regional health information sources.

The Supreme Court is expected to rule next month whether Grokster, a Napster-like file-sharing network for downloading music and other digital entertainment, can be held liable for facilitating copyright infringement. But even if the music industry wins the case, two marketing professors at the W. P. Carey School of Business argue that it will ultimately lose if it keeps fighting consumers. Their research suggests that trying to stem music downloads through legal action and technology is likely to cost the industry more business than it preserves.

Tax breaks are widely promoted by economic development agencies and the business lobby as an effective tool to promote corporate investment. Cities use the offer of tax breaks to lure development - often to prevent neighboring communities from landing the companies with the most potential for creating jobs or sales. The practice is hotly debated, yet despite the controversy public officials appear unlikely to abandon it. An accounting scholar at the W. P. Carey School examined one form of tax incentive - corporate income tax breaks - and found evidence that in fact, the increased investment public officials hope to buy infrequently comes to pass.

For the last 30 years, especially during elections, investors have speculated about the apparent link between stock market behavior and the U.S. presidential election cycle. To the observer, returns seem to be higher during the second half of a president's term than the first. Is it true, or has this phenomenon been merely an intriguing coincidence? A W. P. Carey School of Business finance professor analyzed market behavior going back to 1803 and confirmed that the pattern is real. The reasons why are not so clear.

Donald Trump's weekly pronouncement "You're fired!" makes for blockbuster TV ratings, but as a model for performance evaluation it leaves much to be desired. That's the opinion of W. P. Carey School of Business management professor Robert L. Cardy. His new book, "Performance Management: Concepts, Skills and Exercises," steers managers away from the bellowing/bullying model and toward a cooperative structure in which employees take a more active role. The goal is to make both judges and the judged partners in professional development, for the greater good of the organization.
