6521. Finding Numerical Results to Large Scale Economic Models Using Path-Following Algorithms: A Vintage Capital Example

Abstract:
This paper describes the numerical optimization methods used in Berger (2001) to find the complete time paths of key economic variables in neoclassical vintage capital models. An interior and a non-interior point method are discussed. Both of the methods are part of the general class of “path-following” algorithms. These algorithms can be efficiently applied to convex programming problems; and due to the standard shape of production and utility functions, many economic problems can be written as convex programming problems. Vintage capital models add scale and complexity to standard growth models because one must now handle the dynamics of multiple capital stocks. This increase in complexity will often prevent the discovery (or existence) of closed form solutions, making numerical solutions of the type found in Berger (2001) necessary.

6522. International Comparisons of Productivity Growth: The Role of Information Technology and Regulatory Practices

Abstract:
While information technologies (IT) are credited with the recent acceleration in productivity in the United States, many other industrial countries have not experienced a pickup in productivity growth. To explain this productivity divergence, we use panel data from 1992 to 1999 for 13 industrial countries and find that this divergence is driven in part by differences in both the production and adoption of information technologies. Based on this finding, we proceed to investigate what factors might play a role in explaining differences in IT adoption. Our results support the view that burdensome regulatory environments and in particular regulations affecting labor market practices have impeded the adoption of information technologies and slowed productivity growth in a number of industrial countries. We then develop a theoretical model with vintage capital and labor to evaluate the effect of more stringent labor market regulations on a firm's decision to adopt new technologies. We establish conditions under which a tax on firing workers delays the adoption of IT technology. These conditions occur when technological change is skill-biased and a firm must upgrade the quality of its workforce through labor turnover. The resulting delay in adopting IT technology then has negative implications for economy-wide productivity and is largely consistent with our empirical results.

6523. A Guide to Choosing Absolute Bank Capital Requirements

Author:
Mark Carey
Publication Date:

Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
Resampling implementation of a stress-scenario approach to estimating portfolio default loss distributions is proposed as the basis for estimates of the appropriate absolute level of economic capital allocations for portfolio credit risk. Estimates are presented for stress scenarios of varying severity. Implications of use of different analysis time horizons are analyzed. Results for a numeraire portfolio are quite sensitive to such variations. Although the analysis is framed in terms of recent proposals to revise regulatory capital requirements for banks, the arguments and results are also relevant for bankers making capital structure decisions.

6524. To What Extent Will the Banking Industry be Globalized? A Study of Bank Nationality and Reach in 20 European Nations

Abstract:
We model two dimensions of bank globalization – bank nationality (a bank from the firm's host nation, its home nation, or a third nation) and bank reach (a global, regional, or local bank) using a two-stage nested multinomial logit model. Our data set includes over 2,000 foreign affiliates of multinational corporations operating in 20 European nations. We find that these firms frequently use host nation banks for cash management services, and that bank reach may be strongly influenced by this choice of bank nationality. Our results suggest limits to the degree of future bank globalization.

6525. The Defense Science Board Summer Study on Defense Science and Technology

Publication Date:

Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
Technology has been and must continue to be a key enabler of military advantage, both in conflict and in situations where conflict is close at hand. Over the years, the Department of Defense (DoD) science and technology progrme has discovered, invented, harnessed, and demonstrated such enabling technologies. As industry becomes more global, as scientific endeavors in other countries become more competitive, and as affordable technology increasingly issues from commercial sources, the DoD science and technology program needs to continue to meet challenges and exploit opportunities that arise. The Defense Science Board 2001 Summer Study task force has asked to examine three aspects of the DoD science and technology program: How the Department's S investment should be spend. The level of investment in science and technology. How the military can realize the most value from this investment.

Board of Governors of the Federal Reserve System
Abstract:
The U.S. Commission on International Religious Freedom (the Commission or USCIRF) is the first government commission in the world with the sole mission of reviewing and making policy recommendations on the facts and circumstances of religious freedom violations abroad. The Commission's impact and its success in accomplishing its mission are dependent on bringing advice and accountability to U.S. foreign policy in its promotion of international religious freedom. By providing reliable information and analysis, and careful and creative policy recommendations, the Commission provides the U.S. government and the American public the tools necessary to promote this fundamental freedom throughout the world.

6527. Report on Indonesia

Working Paper

Board of Governors of the Federal Reserve System
Abstract:
Indonesia is a country in major transition. After 40 years of authoritarian rule, a fledgling democratic system has yet fully to take root. The country's first post - authoritarian president, Abdurrahman Wahid, was impeached after two years by the parliament on the grounds of incompetence and replaced by Megawati Sukarnoputri in July 2001. The economy, imbued with corruption during the decades of state control, collapsed in 1997 and has yet to recover. Accustomed to playing a central political and economic role, the Indonesian military remains reluctant to accept civilian control and accountability for its actions. The discontent of the people of several regions with incorporation into the Indonesian state was met for decades with harsh military repression, leaving the essential issues unsolved and, in some cases, aggravated.

6528. Report on Uzbekistan

Publication Date:
05-2002
Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
The conditions for religious freedom are very poor in Uzbekistan. In addition to a highly restrictive law on religion that severely limits the ability of minority religions to function, the Uzbek government in recent years has been harshly cracking down on Muslim individuals, groups, and mosques that do not conform to government-prescribed ideas on how the Islamic faith should be practiced and expressed. This crackdown has resulted in the arrests of thousands of persons and there are credible reports that many have been and continue to be tortured in detention, torture that in some cases has led to the death of those detained. While the government of Uzbekistan does face threats to its security from certain religious groups that have used violence against it, the government's mass arrests of religious believers and reports of torture nevertheless suggest that gravely troubling religious freedom violations are occurring in that country. The Commission recognizes that Uzbekistan only recently gained independence and has not yet developed the institutions and level of civil society necessary for the full protection of human rights, including religious freedom. Nevertheless, this neither excuses nor fully explains the scale and harshness of the government's current campaign against religious freedom.

6529. Equity Prices, Household Wealth, and Consumption Growth in Foreign Industrial Countries: Wealth Effects in the 1990s

Author:
Carol C. Bertaut

Abstract:
Although most recent empirical research regarding the size and significance of the impact of changes in wealth on consumption has looked for such effects in the United States, equity prices in the 1990s rose considerably in most other industrial countries as well. This paper investigates the strength of the wealth effect across countries. Using a variety of methods, I find evidence of significant wealth effects in the United Kingdom and Canada of a size comparable to that in the United States, reflecting the importance of equities in aggregate household wealth in these countries. A significant wealth effect is also evident in Japan, but because household wealth has changed little on balance in Japan in recent years, this channel has been less important in explaining Japanese consumption growth in the second half of the 1990s. Despite a rapid appreciation in equity prices and an increase in equity ownership in the major continental European countries since 1995, equities remain a less important form of household wealth in most of these countries, and the consumption response to changes in wealth remains limited. However, in some smaller European countries where equity issuance is more common, the emerging evidence suggests that wealth effects may be more important.

6530. Financial Centers and the Geography of Capital Flows

Author:
Francis E. Warnock and Chad Cleaver
Publication Date:

Content Type:
Working Paper
Institution:
Board of Governors of the Federal Reserve System
Abstract:
We examine an assumption common in empirical work on bilateral portfolio capital flows that the countries the flows are attributed to are also the countries of the security's issuer, seller, or ultimate buyer. We do this by estimating U.S. investors' holdings of debt and equities in over 40 countries and, for the same countries, foreign investors' holdings of U.S. debt and equities. A comparison of our estimates with data from benchmark surveys provides insight into U.S. data on international debt and equity transactions. We find that, contrary to the common assumption, the data do not track the location of U.S. investment or the location of investors in U.S. assets very well. Because the U.S. portfolio flow data collection system was designed to measure cross-border transactions with foreign counterparties who are often intermediaries, the majority of the flows are attributed to financial centers. By aggregating our country-level estimates, we find that U.S. data accurately portray net inflows into U.S. equities and net outflows into foreign bonds. However, the data substantially overcount net inflows into U.S. bonds and may undercount net outflows into foreign equities. We conclude with a discussion of the implications of our findings for research on capital flows.
