During the next 15 years, globalization, demographic imbalances between OECD and developing countries, and interstate and civil conflicts will fuel increasing international migration, much of it illegal. Migration will have positive and negative consequences for sending and receiving countries alike. Other countries' responses to migration issues will affect migration pressures on the United States and a broad range of US economic and security interests.
In its 1996 report, the Defense Science Board (DSB) recommended that the Pentagon invest an additional $3 billion to strengthen defenses of its information networks. This report was viewed by some as unrealistic and prophetic by others, but in all cases it faced a readership with a very uneven appreciation of the effects of disruptive technology and dicontinuous change. The defense establishment has increased its intellectual capital on the subject of Defensive Information Systems (DIO) considerably since 1996. However, it has yet to fully accomodate the realities of an information intensive future in its architecture, processes, and investments. Technology has continued to evolve and the problems have become much more difficult and complex. DoD must now accomplish more than anyone could have imagined in 1996. Perhaps more important is the dawning realization that incremental modifications to our existing institutions and processes will not produce the adaptation we need.

The United States and its allies face a diverse set of challenges to collective security. These include regional or state-centered threats (such as regional aggressors); transnational threats (including terrorism, international crime, drug trafficking, and illicit arms trafficking); the proliferation of weapons of mass destruction and their means of delivery; and the spread of dangerous technologies (including non-safeguarded, dual-use technologies). Additional challenges include threats to the environment and public health (e.g., new infectious diseases), and from foreign intelligence collection, failed states, and other states that tolerate or actively engage in human rights abuses, ethnic cleansing, or acts of genocide that can endanger regional stability by sparking civil wars and refugee crises.
This paper provides an introduction to forecast uncertainty in empirical economic modeling. Forecast uncertainty is defined, various measures of forecast uncertainty are examined, and some sources and consequences of forecast uncertainty are analyzed. Empirical illustrations with the U.S. trade balance, U.K. inflation and real national income, and the U.S./U.K. exchange rate help clarify the issues involved.
In this paper, we investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. In particular, we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only internationally traded asset, and we compare this welfare level with that obtained under complete asset markets. The welfare cost of incomplete markets is negligible if agents are very patient and shocks are not very persistent, but this cost is dramatically larger if agents are relatively impatient and shocks are highly persistent. For realistic cases in which agents are very patient and shocks are highly persistent (that is, the discount factor and the first-order autocorrelation are both near unity), the welfare cost of incomplete markets is highly sensitive to the specific values of these parameters. Finally, using a non-linear solution algorithm, we confirm that a two-country production economy with endogenous labor supply has qualitatively similar welfare properties.

The National Intelligence Council (NIC) held a conference on 23 February 2001 in cooperation with the Federal Research Division of the Library of Congress on "North Korea's Engagement—Perspectives, Outlook and Implications." The conference featured discussion of seven commissioned papers that are published in this report. Sixty government and nongovernment specialists participated in the conference. Following is a brief summary of the views of the specialists.
The Under Secretary of Defense (AT) requested that the DSB form a brief study of ongoing Navy and Air Force programs aimed at developing advanced laser guided weapon targeting pods for their tactical aircraft. This request for a DSB Task Force was occasioned by Congressional interest in the possibilities of a Joint development and production program for these pods.

The task forces see a spectrum of threats to the homeland emerging. The 2000 summer study begins a series of studies byt he Defense Science Board aimed at assisting the Department of Defense and the Intelligence Community in defining their roles in protecting the nation from unconventional attacks on the United States. Other studies now planned as part of this series of studies include Defense Against Chemical Warfare Attack: Countering the Strategic Nuclear Threat in the 21st century; a follow-up study on Intelligence on Threats to the Homeland; and a second study on the issues associated with Defense Against Biological Warfare Attack. The focus of all these DSB studies is on identifying the technology and operational capability needed to protect the homeland. It is not on the assignment of roles and missions for employing said capabilities. Significant recommendations are made in these reports including suggestions for implementation.

The Under Secretary of Defense (Acquisition, Technology and Logistics), recognizing the crucial importance of weapons platform fuel usage to U.S. military capability, requested that the Defense Science Board form a task force on Improving Fuel Efficiency of Weapons Platforms. Asked to consider existing or emerging technologies that could significantly improve platform efficiency, the task force also examined institutional barriers that exist and must be overcome to understand and capture the full advantages of more efficient military systems.

In late 1998 the Undersecretary of Defense (Personnel Readiness), the Director, Defense Research and Engineering, and the Joint Chiefs of Staff requested the Defense Science Board to create a task force on training and education. Drs. Joe Braddock and Ralph Chatham were appointed co-chairmen. The task force met periodically throughout 1999 and early 2000. This document is the report of our deliberations.
