Mounting evidence across different disciplines suggests that early-life conditions can have consequences on individual outcomes throughout the life cycle. Relative to other developed countries, the United States fares poorly on standard indicators of early-life health, and this disadvantage may have profound consequences not only for population…

China's one-child policy has been an unprecedented policy experiment in human history. Despite its significant achievements, the policy has induced equally significant potential problems. As problems of the one-child policy have been widely noticed and suggestions for adjustments are available, the leadership transition of China in 2012 and 2013…

China has entered into a new stage of demographic dynamics whereby population-related challenges are more complicated than ever before. The current one-child policy should be modified. However, the anticipated impacts of such a policy change should not be over-exaggerated. China's demographic challenge requires an integrated coping strategy.…

Social Security Disability Insurance (SSDI) is an essential lifeline for millions of Americans. Without it, many families would be in deep financial distress. SSDI is insurance that workers pay for through premiums deducted from their pay. In return, workers gain the right to monthly benefits if a disabling condition ends their capacity to earn a…

Current U.S. policy initiatives to improve the U.S. education system, including No Child Left Behind, test-based evaluation of teachers, and the promotion of competition are misguided because they either deny or set to the side a basic body of evidence documenting that students from disadvantaged households on average perform less well in school…

The Social Security Disability Insurance (SSDI) program is growing at an unsustainable pace. Over the past 40 years the number of disabled worker beneficiaries has increased nearly sixfold, rising from 1.5 million in 1970 to 8.2 million in 2010. Rapid growth in the rolls has put increasing pressure on program finances. The rapid rise in SSDI…

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…

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…

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…

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…

For more than 30 years the United States has unsuccessfully struggled to reform its often maligned and massively abused immigration policies. Matters went awry following the passage of the Immigration Act of 1965. There were unexpected consequences. Intended to remove the overtly discriminatory features of the "national origins" admissions system…

New Hope, an employment-based poverty-reduction intervention for adults evaluated in a random-assignment experimental design, had positive impacts on children's achievement and social behavior two and five years after random assignment. The question addressed in this paper was the following: Did the positive effects of New Hope on younger children…

Policy analyses frequently clash. Their disagreements stem from many sources, including models, empirical estimates, and values such as who should have standing and how different criteria should be weighted. We provide a simple taxonomy of disagreement, identifying distinct categories within both the positive and values domains of normative policy…

Jurisdictions are in the process of establishing regulatory systems to control greenhouse gas emissions. Short-term and sometimes long-term emissions reduction goals are established, as California does for 2020 and 2050, but little attention has yet been focused on annual emissions targets for the intervening years. We develop recommendations for…
