Persistent demand from people who have been denied the blessings of parenthood has created an assisted-reproduction market that stretches around the globe and encompasses hundreds of thousands of people. In the United States alone, nearly 41,000 children were born via in vitro fertilization (IVF) in 2001. Roughly 6,000 came from donated eggs, and almost 600 were carried by surrogate mothers. U.S. legislators have been reluctant to regulate this market. As a result, there are no national policies for IVF, which requires creating--and often discarding--embryos, or for many other technologies. State laws vary widely, and many states have no legislation on these subjects whatsoever. Although fertility specialists generally seem delighted to practice in an unregulated gray area, a modicum of regulation and the establishment of agreed-upon norms could lead to substantially lower prices, wider access, and an expansion of the market to the millions who have not yet sought out assisted reproduction. Among those millions are fertile individuals seeking to ensure that they'll be able to produce offspring in the future. For example, the technology already permits young women to freeze their eggs, thus preserving their fertility (in case, for instance, they marry late in life). The fertility trade is in some ways analogous to the markets for personal computers and DVD players, which were initially considered luxury items but migrated to the mass market, earning manufacturers the revenues to finance further innovation. A widening of availability and the introduction of property rights, rules, and institutional policies would make the marketplace more sensitive to the social, medical, and ethical issues that are emerging from the science. For example: Should there be age limits on infertility treatment? Should new procedures be subject to rigorous testing? It is time for U.S. society to begin discussion of these complex questions.  相似文献

Quality of life has been measured in many different ways for patients with chronic medical conditions. What is unique about the approach used here is that it uses suicide rates as a relatively objective measure of quality of life within the population of dialysis patients. Using a Heckman selection model, we estimate the relative suicide rates across patients undergoing both hemodialysis and peritoneal dialysis. Our empirical results show that patients on hemodialysis have relatively lower suicide rates after controlling for other factors. Specifically, our results indicate that 141 fewer suicides will occur for every 1,000 patients shifted from peritoneal to hemodialysis. Prior estimates of the higher costs of the latter modality yield an estimated expenditure of $42,043 per suicide avoided.  相似文献

The present study tests the theory that states can impact the size of the grants they receive (per capita) from the federal government by becoming pivotal players in the federal electoral (primary/caucus) process. That is, by rearranging their presidential primary and caucus dates, states can play an important role in determining the field of candidates for the two major political parties in the United States. States are then likely to be rewarded within the budgetary process at the federal level, which begins with the executive branch. Results from a simultaneous equation system suggest that the impact of the average movement of primaries/caucuses in the sample period (10.36 days closer to 1 January) results in an increase of federal grants of $362 million to $1.2 billion (over a two-year period) for the average state. These results are consistent with the current pattern in the American political process of more front-ended presidential primaries and caucuses.  相似文献

By now, most executives are familiar with the famous Year 2000 problem--and many believe that their companies have the situation well in hand. After all, it seems to be such a trivial problem--computer software that interprets "oo" to be the year 1900 instead of the year 2000. And yet armies of computer professionals have been working on it--updating code in payroll systems, distribution systems, actuarial systems, sales-tracking systems, and the like. The problem is pervasive. Not only is it in your systems, it's in your suppliers' systems, your bankers' systems, and your customers' systems. It's embedded in chips that control elevators, automated teller machines, process-control equipment, and power grids. Already, a dried-food manufacturer destroyed millions of dollars of perfectly good product when a computer counted inventory marked with an expiration date of "oo" as nearly a hundred years old. And when managers of a sewage-control plant turned the clock to January I, 2000 on a computer system they thought had been fixed, raw sewage pumped directly into the harbor. It has become apparent that there will not be enough time to find and fix all of the problems by January I, 2000. And what good will it do if your computers work but they're connected with systems that don't? That is one of the questions Harvard Business School professor Richard Nolan asks in his introduction to HBR's Perspectives on the Year 2000 issue. How will you prepare your organization to respond when things start to go wrong? Fourteen commentators offer their ideas on how senior managers should think about connectivity and control in the year 2000 and beyond.  相似文献
