Human embryonic stem cell (hESC) research has sparked incredible scientific and public excitement, as well as significant controversy. hESCs are pluripotent, which means, in theory, that they can be differentiated into any type of cell found in the human body. Thus, they evoke great enthusiasm about potential clinical applications. They are…

Owen-Smith et al. (this issue) answer the question about expanding funding for human pluripotent stem cell (hPSC) research decisively and emphatically. They conclude that the U.S. federal government should expand funding in volume and scope, and stabilize it through regularity. According to Hurlbut and Robert, If the clear goal of policy should…

This paper articulates a citation-based approach to science policy evaluation and employs that approach to investigate the impact of the United States' 2001 policy regarding the federal funding of human embryonic stem cell (hESC) research. We evaluate the impact of the policy on the level of U.S. hESC research, the U.S. position at the knowledge…

Innovation inducement prizes have been used for centuries. In the United States, a recent federal policy change--the America COMPETES Reauthorization Act of 2010--clarified and simplified a path by which all federal agencies can offer innovation inducement prizes, thus intensifying interest in how government agencies can most effectively design…

Using data from a new household survey on environmental attitudes, behaviors, and policy preferences, we find that current weather conditions affect preferences for environmental regulation. Individuals who have recently experienced extreme weather (heat waves or droughts) are more likely to support laws to protect the environment. We find…

About 75 percent of U.S.-trained, noncitizen PhDs in science and engineering work in the United States after graduation, and 54 percent of those who stay take postdoctoral positions. The probability of postdoctoral participation is substantially higher for temporary visa holders than for permanent visa holders because of visa-related restrictions…

Governments across the world are investing large amounts of money in scientific research, often with the belief that such investments will increase economic growth--yet the scientific evidence for this belief is, as Colin Macilwain notes, "patchy." Science agencies are charged with identifying and funding the best science, yet there is little…

This study empirically examines a prominent justification for public subsidies of emerging technologies: that stimulating demand for them provides opportunities for learning by doing. Even if firms learn from their experience, subsidies are still second best to pricing negative externalities if firms can appropriate the benefits of learning. I…

These are interesting days in the scientific, social, and political debates about human embryonic stem cell research. Pluripotent stem cells--cells that can, in principle, give rise to the body's full range of cell types--were previously derivable only from human embryos that were destroyed in the process. Now, a variety of somatic cell types can…

We examine the effect of gaining prescription drug insurance, as a result of Medicare Part D, on use of prescription drugs and other medical services for a nationally representative sample of Medicare beneficiaries. Given the heightened importance of prescription drugs for those with chronic illness, we provide separate estimates for elderly in…

Urbanization almost invariably accompanies development, and the cities of India and China are experiencing spectacular increases in population. The concentration of millions of people in a small mass creates challenges for public policy, especially in the areas of basic infrastructure, public health, traffic congestion, and often law enforcement…

All industrialized countries are grappling with a common problem--how to provide assistance of various kinds to their rapidly aging populations. The problem for countries searching for models of efficient and high-quality long-term care (LTC) policies is that fewer than a dozen countries have government-organized, formal LTC policies. Relatively…

Voluntary environmental programs (VEPs) are institutions for inducing firms to produce environmental goods beyond legal requirements. A comparative perspective on VEPs shows how incentives to sponsor and participate in VEPs vary across countries in ways that reveal their potential and limitations. Our brief survey examines conditions under which…

Slow economic growth since the end of the U.S. recession in June of 2009 has not yet translated into increases in employment large enough to meaningfully reduce the rate of unemployment. Because expansionary macroeconomic policy has been pursued on both the fiscal and monetary fronts, it appears at first glance that the hands of government at this…

Since U.S. economic growth began to slow in 2006, both the Bush and Obama Administrations have enacted a number of fairly costly programs designed to stimulate the economy and employment growth. Because many of these programs are fairly new, there has been little comprehensive examination of their impacts, but initial analysis suggests that these…
