Images of private forces in Iraq—killed and mutilated in Fallujah, implicated in prisoner abuse at Abu Ghraib, and shooting up civilian vehicles—have provided a dramatic illustration of the role private security companies (pscs) now play in U.S. military operations. Though the United States’ use of contractors on the battlefield is not entirely new, the increased number of contractors deployed and the use of private security forces to perform an escalating number of tasks has created a new environment that poses important trade-offs for U.S. policy and military effectiveness and for U.S. relations with other states. This article outlines the history of U.S. contractors on the battlefield, compares that with the use of private security in Iraq, discusses the benefits and risks associated with their use, and proposes some trade-offs that decision-makers in the United States should consider while contemplating their use in the future.  相似文献

Public concern about the earnings‐related Canada Pension Plan has forced the Canadian government to move toward fuller funding, a new investment policy, and changes to benefits and administration. Together, the three initiatives, and particularly the first two, amount to a modest degree of marketization. The assumption behind the reform is that the Canada Pension Plan will remain public and mandatory but the change will create a board and an investment policy which are more sensitive to market pressures and less amendable to government interference. The Canada Pension Plan is one of three tiers of support for the elderly in retirement. It is a contributory social insurance scheme which protects against loss of income. The other two are a social allowance (Old Age Security) as well as an income tested benefit (Guaranteed Income Supplement) which provide basic income support and employment based retirement pension plans as well as group and individual registered retirement savings plans which supplement the other two tiers on a voluntary basis. This article examines the reform of the Canada Pension Plan. After a brief examination of Canada's retirement benefits in an international context, the article summarizes recent debates in Canada, government policies to develop fuller funding and new investment strategies, and reflections on possible developments in the future.  相似文献

Abstract

This paper provides a comprehensive evaluation of market segmentation and lender/purchaser specialization in the primary and secondary mortgage markets. It describes and assesses the 1990 Home Mortgage Disclosure Act (HMDA) data, which for the first time provide detailed information on the borrower and neighborhood racial and income characteristics of mortgage loan originations and securitizations in the primary and secondary mortgage markets. Evidence presented in the paper indicates that home purchase loan origination rates for black applicants—and, to a lesser degree, Hispanic applicants—appear to be significantly lower than those of other racial or ethnic groups. Similarly, the HMDA data reveal that home purchase mortgage origination rates in predominantly minority census tracts are significantly lower than those in predominantly white neighborhoods. The HMDA data also indicate a striking reliance of black borrowers on government‐backed forms of mortgage credit.

The paper further reveals that secondary market loan purchase distributions arrayed by borrower and neighborhood characteristics generally reflect those of home mortgage originations. The borrower and locational characteristics of home purchase loans acquired by the Government National Mortgage Association (GNMA) directly reflect that agency's legislated specialization in government‐backed loans, whereas the characteristics of loans acquired by Fannie Mae and Freddie Mac for the most part derive from the borrower and geographic composition of conventional home purchase loan originations. Findings of analyses of HMDA data raise concern regarding the access of minority and low‐income households and neighborhoods to mortgage finance. Those results also raise some question as to whether the federally chartered agencies in the secondary market are adequately promoting the availability of mortgage credit to low‐ and moderate‐income and minority households.  相似文献
