1 Owing to the widespread expansion of casinos, the cost of pathological and problem gambling has soared to nearly half the annual cost of drug abuse in the United States, a UI expert says in a new book.
2 The social costs of gambling, such as increased crime, lost work time, bankruptcies and financial hardships faced by the families of gambling addicts, have reached epidemic proportions, costing the economy as much as $54 billion annually, Earl L. Grinols, an Illinois economist, has written in "Gambling in America: Costs and Benefits," published this month by Cambridge University Press.
3 This compares with the estimated annual $110 billion cost of drug abuse, according to the U.S. General Accounting Office.
4 Casino gambling causes up to $289 in social costs for every $46 of economic benefit, according to Grinols: "In 2003 dollars, the cost to society of an additional pathological gambler is $10,330 based on studies performed in the mid-1990s, whereas the cost to society of an additional problem gambler is $2,945", he wrote. Accounting for the cost of raising tax dollars to cover some of these costs raises the totals to $11,304 and $3,222, respectively.
5 A former senior economic adviser to President Ronald Reagan, Grinols wrote the book because there is "a great unfulfilled need for an economist to study the costs and benefits of casinos in society and to identify which side of the ledger [is] predominant."
6 He pointed out that nearly all research on gambling consists of industry-sponsored studies ballyhooing new jobs and increased taxes.
7 His book includes economic analyses that put price tags on the inflows and outflows of gambling money.
8 On the positive side of the ledger, a casino may increase local employment and raise state and local tax revenues. In Las Vegas and Atlantic City, N.J. , where casinos primarily serve tourists, gambling creates regional jobs and an inflow of revenues.
9 However, in the Midwest and South, where casinos primarily attract a local clientele, gambling causes a net loss to the community. Not only do out-of-state casino operators remove gambling dollars from the local economy, but local employers and taxpayers must foot the bill of increased crime, personal bankruptcy, domestic violence, lost workdays, child abuse and other social costs from problem gamblers.

Saying they can no longer ignore the rising prices of health care, some of the most influential medical groups in the nation are recommending that doctors weigh the costs, not just the effectiveness of treatment, as they make decisions about patient care.
The shift, little noticed outside the medical establishment but already controversial inside it, suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent.
In practical terms, the new guidelines being developed could result in doctors choosing one drug over another for cost reasons or even deciding that a particular treatment-at the end of life, for example-is too expensive. In the extreme, some critics have said that making treatment decisions based on cost is a form. of rationing.
Traditionally, guidelines have heavily influenced the practice of medicine, and the latest ones are expected to make doctors more conscious of the economic consequences of their decisions, even though there’s no obligation to follow them. Medical society guidelines are also used by insurance companies to help determine reimbursement(报销)policies.
Some doctors see a potential conflict in trying to be both providers of patient care and financial overseers.
"There should be forces in society who should be concerned about the budget, but they shouldn’t be functioning simultaneously as doctors," said Dr. Martin Samuels at a Boston hospital. He said doctors risked losing the trust of patients if they told patients, "I’m not going to do what I think is best for you because I think it’s bad for the healthcare budget in Massachusetts."
Doctors can face some grim trade-offs. Studies have shown, for example, that two drugs are about equally effective in treating macular degeneration, an eye disease. But one costs $50 a dose and the other close to $2,000. Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug. Avastin, instead of the costlier one, Lucentis.
But the Food and Drug Administration has not approved Avastin for use in the eye, and using it rather than the alternative, Lucentis, might carry an additional, although slight, safety risk. Should doctors consider Medicare’s budget in deciding what to use？
"I think ethically(在道德层面上)we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole," said Dr. Donald Jensen.
Still, some analysts say that there’s a role for doctors to play in cost analysis because not many others are doing so. "In some ways," said Dr. Daniel Sulmasy, "it represents a failure of wider society to take up the issue."
