Sub-Saharan Africa has been far more severely affected by AIDS than any other part of the world. The United Nations reports that 29.4 million adults and children are infected with the HIV virus in the region, which has about 10% of the world's population but more than 70% of the worldwide total of infected people. This report discusses this issue in detail, including the cause of the African AIDS epidemic, the social and economic consequences, response and treatment, and U.S. policy.

This report discusses issues debated in the 107th Congress while is considering various proposals to amend the Endangered Species Act of 1973 (ESA). Major issues in recent years have included changing the role of science in decision-making, changing the role of critical habitat, reducing conflicts with Department of Defense activities, incorporating further protection for property owners, and increasing protection of listed species, among others. In addition, many have advocated including significant changes to ESA regulations made during the Clinton Administration in the law itself.

The idea of replacing our current income tax system with a “flat-rate tax” is receiving renewed congressional interest. Although referred to as “flat-rate taxes,” many of the current proposals go much further than merely adopting a flat-rate tax structure. Some involve significant income tax base broadening while others entail changing the tax base from income to consumption.

This report discusses the funding authorizations for programs in the Higher Education Act (HEA). This legislation, administered by the U.S. Department of Education (ED), authorizes the federal government’s major student aid programs, as well as other significant initiatives.

Proposals to replace all or part of the income tax, proposals for national health care, and a proposal to finance America’s war effort have sparked congressional interest in the possibility of a broad-based consumption tax as a new source of revenue. A value-added tax (VAT) or a national sales tax (NST) have been frequently discussed as possible new tax sources. Both the VAT and the NST are taxes on the consumption of goods and services and are conceptually similar. Yet, these taxes also have significant differences. This issue brief discusses some of the potential policy implications associated with these differences.

The United States recognized the independence of all the former Soviet republics by the end of 1991, including the South Caucasus states of Armenia, Azerbaijan, and Georgia. The United States has fostered these states' ties with the West in part to end the dependence of these states on Russia for trade, security, and other relations. The FREEDOM Support Act of 1992 provides authorization for assistance to the Eurasian states for humanitarian needs, democratization, and other purposes. In the aftermath of the September 11, 2001, terrorist attacks on the United States, the Administration appealed for a national security waiver of the prohibition on aid to Azerbaijan, in consideration of Azerbaijan's assistance to the international coalition to combat terrorism. Azerbaijani and Georgian troops participate in stabilization efforts in Afghanistan and Iraq, and Armenian personnel serve in Iraq.

Over the past decade, worldwide production of illicit drugs has risen dramatically: opium and marijuana production has roughly doubled and coca production tripled. Street prices of cocaine and heroin have fallen significantly in the past 20 years, reflecting increased availability. Despite apparent national political resolve to deal with the drug problem, inherent contradictions regularly appear between U.S. anti-drug policy and other national policy goals and concerns. The mix of competing domestic and international pressures and priorities has produced an ongoing series of disputes within and between the legislative and executive branches concerning U.S. international drug policy. One contentious issue has been the Congressionally-mandated certification process, an instrument designed to induce specified drug-exporting countries to prioritize or pay more attention to the fight against narcotics businesses.

The Bush Administration issued its plan for a national energy policy on May 16, 2001. The plan was controversial, characterized by some as leaner on conservation and renewables than Democratic proposals, and predisposed to trade off environmental considerations to increase supply. Comprehensive energy legislation was introduced in the Senate by both parties by late March (S. 388, S. 389, S. 596, S. 597). Bills reported by several House committees (H.R. 2436, H.R. 2460, H.R. 2511, and H.R. 2587) were combined in a single bill, H.R. 4, passed by the House, August 1, 2001. The House version of H.R. 4 would require a 5 billion gallon reduction in light-duty truck and SUV fuel consumption and would open the Arctic National Wildlife Refuge (ANWR) to leasing.

On April 9, 2001, the President requested $7.3 billion in discretionary budget authority for the Environmental Protection Agency (EPA) for FY2002, $512.0 million (or 7%) less than the FY2001 funding level of $7.8 billion. The request would not have continued funding of about $500 million for activities earmarked for FY2001, and contained provisions shifting more enforcement responsibilities to the states. Popular wastewater infrastructure funding, state roles, and the future of Superfund were some of the predominant topics. On July 17, the House Appropriations Committee recommended $7.545 billion,$229 million more than requested (H.R. 2620, H. Rept. 107-159).

The Federal Railroad Administration of the U.S. Department of Transportation is the primary federal agency that promotes and regulates railroad safety. To implement its safety responsibilities, the Federal Railroad Administration uses numerous strategies including the Safety Assurance and Compliance Program, field inspections; and to help improve its regulations, the administration uses the Railroad Safety Advisory Committee. This report contains information on the Federal Railroad Administration's Safety Program, railroad safety statistics, key reauthorization issues, and related information.

Some Members of Congress have expressed interest in the feasibility of using a value-added tax (VAT) to either replace all or part of the income tax or finance health care reform. A VAT is imposed at all levels of production on the differences between firms' sales and their purchases from all other firms. Policymakers may be interested in the following aspects of a VAT: revenue yield, international comparison of composition of taxes, vertical equity, neutrality, inflation, balance-of-trade, national saving, administrative cost, intergovernmental relations, size of government, and public opinion.
