An Assessment of the Effectiveness of Anti-Poverty Programs in the United States
We assess the effectiveness of means-tested and social insurance programs in the United States. We show that per capita expenditures on these programs as a whole have grown over time but expenditures on some programs have declined. The benefit system in the U.S. has a major impact on poverty rates, reducing the percent poor in 2004 from 29 percent to 13.5 percent, estimates which are robust to different measures of the poverty line. We find that, while there are significant behavioral side effects of many programs, their aggregate impact is very small and does not affect the magnitude of the aggregate poverty impact of the system. The system reduces poverty the most for the disabled and the elderly and least for several groups among the non-elderly and non-disabled. Over time, we find that expenditures have shifted toward the disabled and the elderly, and away from those with the lowest incomes and toward those with higher incomes, with the consequence that post-transfer rates of deep poverty for some groups have increased. We conclude that the U.S. benefit system is paternalistic and tilted toward the support of the employed and toward groups with special needs and perceived deservingness.
Do Estate and Gift Taxes Affect the Timing of Private Transfers?
Proposals to alter the estate tax are contentious and have been debated largely in an empirical vacuum. This paper examines time series and cross-sectional variation to identify the effects of gift and estate taxation on the timing of private transfers. The analysis is based on data from the 1989, 1992, 1995, and 1998 waves of the Surveys of Consumer Finances. Legislative activity during this period reduced the tax disadvantage of bequests relative to gifts. Moreover, the magnitude of this reduction differed systematically across identifiable household categories. We find that households experiencing larger declines in the expected tax disadvantages of bequests substantially reduced inter vivos transfers relative to households experiencing small declines in the tax disadvantages of bequests. This implies that the timing of transfers is highly responsive to applicable gift and estate tax rates. These conclusions are based both on simple comparisons of the probability of giving across different time periods and groups, and on empirical specifications that control for a variety of potentially confounding factors, such as systematic changes in the fraction of wealth attributable to unrealized capital gains. The results also provide evidence of a systematic bequest motive for some high-wealth households.

Changing Climate and Land Use: Consequences for 100-Year Flooding in the Lamprey River Watershed of New Hampshire
Helping the Working Poor: Employer- vs. Employee-Based Subsidies
In the United States and Europe there has been renewed interest in subsidizing firms that employ disadvantaged workers as a means of addressing poverty and other social problems. In contrast, the prevailing practice is largely to provide social welfare benefits directly to individuals. Which approach is better? We re-examine the relative merits of employee- versus employer-based labor market subsidies and conclude there are good reasons to continue to rely on the direct, employee-based approach. In practice, low-wage workers are seldom either low-skill or low-income workers. Furthermore, workers who might quality for a firm-based subsidy are reluctant to so identify themselves for fear of being stigmatized or labeled as needy. Thus, employer-based subsidy programs have lower participation rates and correspondingly higher per capita expenditures than employee-based subsidy programs
Mapping and Legal Implications of Future Flooding in the Lamprey River Watershed of New Hampshire Due to Changes in Land Use and Climate
At Sea Test 2 deployment cruise : cruise 475 on board R/V Oceanus September 22 – 26, 2011 Woods Hole –Woods Hole, MA
The R/V Oceanus, on Cruise 475, carried out the deployment of three moorings for the
Coastal and Global Scale Nodes (CGSN) Implementing Organization of the NSF Ocean
Observatories Initiative. These three moorings are prototypes of the moorings to be used
by CGSN at the Pioneer, Endurance, and Global Arrays. Oceanus departed from Woods
Hole, Massachusetts on September 22, 2011 and steamed south to the location of the
mooring deployments on the shelf break. Over three days, September 23-25, Oceanus
surveyed the bottom at the planned mooring sites, deployed the moorings, and carried out
on site verification of the functioning of the moorings and moored hardware. Oceanus
returned to Woods Hole on September 26, 2011.Funding was provided by the National Science Foundation

Continuous 1.3-Million-Year Record of East African Hydroclimate, and Implications for Patterns of Evolution and Biodiversity
The transport of moisture in the tropics is a critical process for the global energy budget and on geologic timescales, has markedly influenced continental landscapes, migratory pathways, and biological evolution. Here we present a continuous, first-of-its-kind 1.3-My record of continental hydroclimate and lake-level variability derived from drill core data from Lake Malawi, East Africa (9–15° S). Over the Quaternary, we observe dramatic shifts in effective moisture, resulting in large-scale changes in one of the world’s largest lakes and most diverse freshwater ecosystems. Results show evidence for 24 lake level drops of more than 200 m during the Late Quaternary, including 15 lowstands when water levels were more than 400 m lower than modern. A dramatic shift is observed at the Mid-Pleistocene Transition (MPT), consistent with far-field climate forcing, which separates vastly different hydroclimate regimes before and after ∼800,000 years ago. Before 800 ka, lake levels were lower, indicating a climate drier than today, and water levels changed frequently. Following the MPT high-amplitude lake level variations dominate the record. From 800 to 100 ka, a deep, often overfilled lake occupied the basin, indicating a wetter climate, but these highstands were interrupted by prolonged intervals of extreme drought. Periods of high lake level are observed during times of high eccentricity. The extreme hydroclimate variability exerted a profound influence on the Lake Malawi endemic cichlid fish species flock; the geographically extensive habitat reconfiguration provided novel ecological opportunities, enabling new populations to differentiate rapidly to distinct species
