Abstract:
Although computers are universal in the classroom, nearly twenty million children in the United States do not have computers in their homes. Surprisingly, only a few previous studies explore the role of home computers in the educational process. Home computers might be very useful for completing school assignments, but they might also represent a distraction for teenagers. We use several identification strategies and panel data from the two main U.S. datasets that include recent information on computer ownership among children -- the 2000-2003 CPS Computer and Internet Use Supplements (CIUS) matched to the CPS Basic Monthly Files and the National Longitudinal Survey of Youth 1997 -- to explore the causal relationship between computer ownership and high school graduation and other educational outcomes. Teenagers who have access to home computers are 6 to 8 percentage points more likely to graduate from high school than teenagers who do not have home computers after controlling for individual, parental, and family characteristics. We generally find evidence of positive relationships between home computers and educational outcomes using several identification strategies, including controlling for typically unobservable home environment and extracurricular activities in the NLSY97, fixed effects models, instrumental variables, and including future computer ownership and falsification tests. Home computers may increase high school graduation by reducing non-productive activities, such as truancy and crime, among children in addition to making it easier to complete school assignments.

Abstract:
We study the association between order flow and exchange rate returns in five years of high-frequency intraday data from the leading interdealer electronic broking system, EBS. While the association between order flow and exchange rate returns has been studied in several previous papers, these have mostly used relatively short spans of daily data from older bilateral dealing systems and, usually, transaction counts instead of actual trading volume. Using a substantially longer span of recent high-frequency data and measuring order flow as actual signed trading volume, we find a strong positive association between order flow and exchange rate returns at frequencies ranging from one minute to one day, and a more modest but still sizeable association at the monthly frequency. We find, however, no evidence that order flow has predictive power for future exchange rate movements beyond, possibly, the next minute. Focusing on the behavior of order flow and exchange rates at the time of scheduled U.S. economic data releases, we find that the surprise components of these announcements are associated with order flow at high frequency immediately after the data releases. This finding seems inconsistent with a simple efficient markets view of how a public news announcement is incorporated into prices.

3. A Flexible Finite-Horizon Identification of Technology Shocks

Working Paper

Abstract:
Recent empirical studies using infinite horizon long-run restrictions question the validity of the technology-driven real business cycle hypothesis. These results have met with their own controversy, stemming from their sensitivity to changes in model specification and the general poor performance of long run restrictions in Monte Carlo experiments. We propose a alternative identification that maximizes the contribution of technology shocks to the forecast error variance of labor productivity at a long, but finite horizon. In small samples, our identification outperforms its infinite horizon counterpart by producing less biased impulse responses and technology shocks that are more highly correlated with the technology shocks from the underlying model. For U.S. data, we show that the negative hours response is not robust to allowing a greater role for non-technology shocks in the forecast error variance share at a ten year horizon.

4. International Risk-Sharing and the Transmission of Productivity Shocks

Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to efficient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that a standard international business cycle model with incomplete asset markets augmented with distribution services can account quantitatively for these properties of real exchange rates. Distribution services, intensive in local inputs, drive a wedge between producer and consumer prices, thus lowering the impact of terms-of-trade changes on optimal agents' decisions. This reduces the price elasticity of tradables separately from assumptions on preferences.

5. Can Long-Run Restrictions Identify Technology Shocks?

Abstract:
Gali's innovative approach of imposing long-run restrictions on a vector autoregression (VAR) to identify the effects of a technology shock has become widely utilized. In this paper, we investigate its reliability through Monte Carlo simulations using calibrated business cycle models. We find it encouraging that the impulse responses derived from applying the Gali methodology to the artificial data generally have the same sign and qualitative pattern as the true responses. However, we find considerable estimation uncertainty about the quantitative impact of a technology shock on macroeconomic variables, and little precision in estimating the contribution of technology shocks to business cycle fluctuations. More generally, our analysis emphasizes that the conditions under which the methodology performs well appear considerably more restrictive than implied by the key identifying assumption, and depend on model structure, the nature of the underlying shocks, and variable selection in the VAR. This cautions against interpreting responses derived from this approach as model-independent stylized.

Abstract:
In 2001, the Under Secretary of Defense for Acquisition, Technology and Logistics (USD(AT)) directed the Defense Science Board (DSB) to study the precision targeting of air-delivered munitions. The results of the 2001 Task Force were well-received within Office of the Secretary of Defense (OSD), and in June 2003, USD(AT) directed the DSB to study the closely related topic of “integrated fire support in the battlespace.” In this new study the 2003 Task Force applied an approach and methodology similar to the 2001 effort but focused instead on ground-based fires, sea-based fires, and close-air support.

Institution:
Board of Governors of the Federal Reserve System
Abstract:
In February 2003, the Office of the Deputy Under Secretary of Defense for Industrial Policy, ODUSD(IP), produced Transforming the Defense Industrial Base: A Roadmap. This report identified the need for systematic evaluation of the ability of the defense industrial base to develop and provide functional, operational effects-based warfighting capabilities. The Defense Industrial Base Capabilities Study (DIBCS) series is a systematic assessment of critical technologies needed in the 21st century defense industrial base to meet warfighter capabilities, as framed by the Joint Staff's functional concepts. In addition, the DIBCS series provides the basis for strengthening the industrial base required for 21st century warfighting needs. This report addresses the third of those functional concepts, Force Application.

8. Defense Science Board Report on Corrosion Control

Publication Date:

Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
Weapons system readiness and safety are among the highest priority challenges for the Department of Defense (DoD). As it continues to receive a large number of mission taskings, it is imperative that DoD equipment be maintained at an acceptable level of material condition so that it may be employed safely and effectively when required, often in harsh and physically demanding environments. However, both the material condition and safety of DoD equipment are routinely being undermined by the effects of corrosion. The dollar cost of corrosion to DoD has been estimated by the Government Accountability Office (GAO) to be $10-20 billion per year. Aggressive action is needed at every stage in the life cycle of this equipment — during design, materials selection, construction, operation, and maintenance — to reduce the negative effects of corrosion.

10. The Vertical Lift Industrial Base: Outlook 2004-2014

Publication Date:
07-2004
Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
The vertical lift industrial base still is being shaped by government and industry responses to the Nunn-McCurdy cost breaches of 2001 and the unintended consequences of Department-endorsed teaming arrangements that resulted in an interlocked industrial base that restricted Department and industry flexibility. The Department's budget-driven remanufacture strategy in the 1990s produced a series of sole-sourced relationships, leaving few real competitive opportunities among the helicopter prime contractors to force technology refresh cycles. With limited competition, few new platform contracts, and declining government technology investments, industry was left little incentive to invest in independent research.
